The principle of 3D stereoscopic display technology and the game application history Introduction "Go"

This article is from Zhongguancun Zol

"3d stereoscopic display" can be said to be the latest entertainment industry is quite hot topic, not only has Hollywood launched "Avatar" and other blockbuster 3D Imax, the world's major home appliances manufacturers are also actively layout ready to launch a series of 3D stereoscopic display of the player and TV and other home appliances, NVIDIA also launched support 3D Stereoscopic display card and peripheral, even SCE and Nintendo also successively published PS3 and NDS successor machine species of 3D stereoscopic display support.

This article will be a brief introduction to the principle and application of 3D stereoscopic display, to understand how 3D stereoscopic display is to reproduce the real-world stereoscopic, and 3D stereoscopic display in the game field of practical application, for the player reference.

　　The composition of stereoscopic vision

The reason why we can feel stereoscopic vision is that the human eyes are laterally and 6~7 centimeters apart, so the images seen in the left eye are slightly different from those seen in the right eye, and this difference is called " Parallax (Parallax), the brain interprets the parallax of the eyes and determines the distance and the resulting stereoscopic vision of the object.

Disparity

When viewers only look at the scene in one eye, because there is no parallax, so the three-dimensional sense will disappear with it.

　　Fundamentals of 3D Stereoscopic display

Because stereoscopic vision is based on Parallax, so the basis of 3D stereoscopic display is to reproduce the parallax by artificial means, simply to find a way to let the left and right eyes see different images, so as to simulate the stereoscopic vision. Under this foundation developed a variety of 3D stereoscopic display technology, mainly divided into two types of glasses and naked eye.

　　The origin of the 3D stereoscopic display

The 3D stereoscopic display has a long history and has appeared since the beginning of the 19th century photographic technology. The practice is to pair 2 cameras together to simulate the eyes, while taking the 2 slightly different photos, and then through the parallel line of sight, cross-line line of sight, or similar to the binoculars of the exclusive viewing equipment, and so on to see the eyes of 2 parallel photos.

　 Parallel Line of sight method: Let the eyes parallel to each other, left and right to see photos

Example of parallel line of sight method

　　Cross Line of sight: Move the binocular viewpoint closer to the eye (cross-eyed) to see the left and right side of the picture

Example of cross-gaze method

The above two methods do not need special equipment to be able to view the stereoscopic image on the general plane medium, but because it is viewed with unnatural sight, not everyone can adapt, the burden to the eye is also big, the practicality is not high.

Double mirror tube-type of the exclusive viewing equipment can clearly separate the eyes of the eye, do not need to let the viewer himself to adjust the line of sight to capture the sense of the three-dimensional, so most people can adapt, this way followed by the development of the head-mounted 3D stereoscopic display screen, through the left and right two sets of screens to see different images of the

19th century double mirror barrel exclusive viewing equipment manufactured

But the above-mentioned ways can only be viewed by one person at a time, not suitable for many people to appreciate the needs of the application.

In order to meet the needs of many people such as movies and other applications, so the follow-up also appeared with special glasses to provide multi-person viewing of the various 3D stereoscopic display, and according to the mode of operation is divided into passive and active two major categories.

"Passive 3D stereo Glasses"

Passive 3D stereoscopic glasses refer to the spectacles themselves as mere lenses + frames, and do not involve any mechanical or electronic operation. Although there are many different techniques used in these spectacles, the basic principle is that the two sets of images can only pass through the lens of one eye, allowing the left and right eye to see parallax images.

˙ Red-Blue filter 3D stereo glasses

The earliest is the use of red and blue (or red and green) filter made of 3D stereoscopic glasses, the cost of the glasses itself is very low (can be made with red and blue cellophane and cardboard), the early 3D IMAX used this way, respectively, the projection of the red filter and Blue Filter screen, and then let the viewer wear red and blue 3D Stereo glasses to watch.

Red and blue color filter 3D stereo Glasses

The red and blue color filter method can be applied to print media or general display equipment.

Batman: Clown Escape in red and blue 3D mode

Due to the red and blue filter 3D stereoscopic glasses have not correctly reproduce the original picture of the shortcomings of the color, so the following manufacturers have introduced the modified type of "colorcode 3d", the color and monochrome two sets of images are presented by the amber and blue filters, and the color stereoscopic images can be obtained because the brain automatically combines the images viewed by the eyes.

˙ polarizing 3D Stereo glasses

After the popularization of polarized technology, the company began to adopt polarized passive 3D stereoscopic glasses. The polarizer is a silicon crystal coating film (polarizing film) arranged in a shutter-like way to filter the light that would otherwise vibrate in different directions, blocking the light perpendicular to the direction of the polarizing film, allowing only the same light to pass in the direction of the polarizing film. Because the polarizer only filters the direction of the light, it does not filter the color of the light like a filter, so the color of the picture can be preserved intact.

Polarization principle

As long as the two sets of devices are used to project a vertical polarization and horizontal polarization through the polarizer, or a set of devices with a switchable polarization of the active polarizing film alternately projected vertical polarization and horizontal screen, and then let the viewer wear vertical polarizer and horizontal polarizer combination of polarized 3D stereo glasses, You can watch the stereoscopic picture.

Polarizing 3D Stereo Glasses

When applied to a liquid crystal display, it is expensive to use two overlapping LCD panels to display vertical and horizontal polarized images respectively. Alternatively, configure the vertical and horizontal polarizer on the screen surface with the odd-even staggered arrangement, each using half of the pixels to display vertical and horizontal polarized images, which is less expensive, though the vertical or horizontal resolution will be halved.

Scet display of 3D LCD TVs with staggered polarizing plates

Most of the 3D Imax in recent years have been represented by polarizing methods. However, polarizing methods must be presented using a special projector or a display device such as a screen, and therefore not suitable for print media or general display devices.

"Active 3D Stereo Glasses"

Active 3D stereoscopic glasses are achieved through the active operation of the glasses themselves to achieve the 3D stereoscopic display effect.

˙ Dual-monitor 3D stereo glasses

Dual-monitor 3D stereoscopic glasses Although can not provide multi-person viewing needs, but still even is active 3D stereo glasses of one kind, the principle of operation is very simple, through the two groups of small monitors configured in the left and right glasses to display the left and right eye screen individually, to achieve the effect of stereoscopic display. Because two separate sets of monitors must be configured, they are expensive and can only be viewed by single person. Therefore, it is often used only for special purposes, such as with head detection applications in virtual reality.

Head-mounted Display

Nintendo's Portable game console, "virtual Boy (VB), launched in 1995, is such a design.

˙ LCD 3D Stereoscopic Glasses

Liquid Crystal 3D Stereoscopic glasses is the use of active liquid crystal lens composed of 3D stereoscopic glasses, the use of liquid crystal can be used by the electric field to change the principle of light transmission, the frequency of dozens of times per second to shade the eyes of the left and right eye alternately. Play as long as the left and right eye screen alternately display, and then through the synchronous signal to allow the LCD 3D stereoscopic glasses and the screen to operate synchronously, broadcast the left eye screen to make the right eye lens black, broadcast the left eye lens to black, you can achieve the effect of stereoscopic display.

Because the liquid crystal 3D stereo glasses do not need to filter color or polarization and other special structure of the playback equipment can be presented, only need to enhance the playback equipment screen update frequency and the addition of synchronous signal sending device can be applied to large-size multi-person viewing needs, is currently the most widely used in 3D TV and other areas of livelihood entertainment. The "3d vision", which was launched by NVIDIA on the PC, as well as the recent 3D stereoscopic TV products from various appliance manufacturers, are used in this way.

As the picture is the right and left alternately play, only one eye can see the picture at the same time, so when the 3D stereoscopic display mode is turned on, the screen refresh rate will change to half the original. If you only match the existing 60 updates per second standard specifications, the screen refresh rate will be reduced to 30 times per second, so that viewers feel a noticeable flicker. So at present, each manufacturer's solution is to double the screen refresh frequency to 120 times per second to avoid flashing problems.

LCD 3D Stereoscopic glasses must be active, so the structure is more complex than passive 3D stereo glasses, although the cost of the playback equipment is lower, but the cost of glasses is much higher. In the current mainstream infrared synchronization method, it must be equipped with additional receiving control circuit and battery. And the interlaced shielding of the LCD lens will affect the brightness of the screen.

Although LCD 3D stereoscopic glasses This two years with the introduction of new products began to fever, but in the game field of application in fact has more than 20 years, the earliest is SEGA in 1986 launched SEGA Markiii/master System with the "3d glasses", Nintendo also in 198 7-year launch of the Famicom "famicom 3D system".

However, the liquid crystal 3D glasses around the design to accommodate the existing ntsc/pal specifications image tube screen, play when the brightness of the picture is strong, and the game machine at that time, there is no 3D graphics ability, can only be presented with a layer of layers, and so did not get the market favor, There are also quite a few supported games.

Although the glasses can meet the needs of many people to see together, but the need to wear special glasses when watching is still a considerable obstacle, the manufacturers put into the glasses do not need to wear the naked eye 3D stereoscopic display technology research and development.

The so-called "naked eye 3D stereoscopic display" refers to the effect that the 3D stereoscopic display can be viewed directly without wearing any special accessory in the condition of naked eyes. Although the rationale is still to allow the right and left eye to watch different images create parallax to create three-dimensional sense, but the premise is not wearing glasses, so must through the special design of the screen to achieve the goal.

Because the naked eye 3D stereoscopic display has many limitations in technology, it is mainly used for the display use of personal miniaturization, such as mobile phone, digital camera, etc., less used for large-scale display use, such as TV screen.

The open-hole 3D stereoscopic display is divided into two categories: spatial multi-work and time-sharing, according to Operation mode.

"Spatial multi-function open-hole 3D stereoscopic display"

Space Multi-function glasses 3D stereoscopic display is on the same screen, in order to split the display area (space) while showing the left and right two-eye screen (multirole) to achieve a 3D stereoscopic display effect, it is called "spatial multi-function".

˙ Cylindrical lens Type 3D stereoscopic display (lenticular Lenses)

Cylindrical lens type 3D stereoscopic display screen, is a vertical arrangement on the screen surface of the cylinder convex lens film, through the refraction of the lens to control the direction of the light, so that the left and right two eyes to receive different images to create a three-dimensional parallax appearance.

By the way the light is passing through the convex lens, the direction of travel will refract and change, so as long as the left and right eye images are staggered vertically, and then through a series of tightly arranged cylindrical lenses, you can see the respective picture.

Cylindrical lens is a long history, the scope of application is also quite extensive, including graphic printing or screen display can use this method to present 3D stereoscopic picture, the market common three-dimensional pads and other products are made using the same principle. In addition to rendering stereoscopic images, cylindrical lenses can also be used to visualize images that change with viewing angles.

"Dante's Journey to Hell" Death Special edition cover is the use of cylindrical lens printing

Because the cylindrical lens can produce a stereoscopic effect at multiple angles, it can be used for multi-person viewing applications, although there is a situation where images overlap when viewed at an inappropriate angle. The general cylindrical lens is fixed attached to the screen surface, and is arranged in a single direction, so it is not possible to switch the display mode, the level of resolution will be reduced to the original half, the picture quality will be affected by the lens refraction, the screen rotated 90 degrees will not be able to show three-dimensional sense. However, there are also manufacturers to develop a cylindrical lens to inject liquid crystals to change the focus characteristics of the technology, can turn off the lens of the refraction effect switch to the model.

˙ parallax Barrier Type 3D stereoscopic display (Parallax barriers)

Parallax Barrier Type 3D Stereoscopic display screen, is set up on the screen surface called "parallax Barrier" of the longitudinal fence-like optical barrier to control the direction of light travel, so that the left and right two eyes to accept different images produced parallax to achieve stereoscopic display effect.

Because the eyes of the left and right eye through the fence-like parallax barrier angle is different, so you will see the different parts of the back screen, as long as the left and right eye picture in the vertical staggered arrangement, you can let the eyes to the respective screen to produce three-dimensional sense.

Due to the use of masking method to achieve stereoscopic display, the screen must be divided into two left and right display, so the level of resolution will be reduced to half the original, and the brightness of the screen will be reduced. There will also be a viewing distance, angle and direction restrictions, must be in the specified distance and angle of view, the screen turn 90 degrees will not be able to show three-dimensional.

Follow-up manufacturers to develop a number of technologies to improve the Parallax barrier 3D stereoscopic display screen of the inherent limitations, such as the use of switchable liquid Crystal Film to act as a parallax barrier, can be through the LCD barrier switch to switch 2d/3d display mode, liquid crystal barrier arrangement can also be made into horizontal and vertical two directions, With the need to switch between the cross and straight take.

switchable LCD Parallax Barrier

Parallax Barrier Type 3D stereoscopic display is currently the most widely used in portable devices, including both Sharp and Hitachi in the same time after the release of Nintendo N3DS after the release of their mobile phone with parallax barrier type 3D stereoscopic display screen. Sharp's products combine liquid crystal barriers with touch-controlled films, while supporting cross-and direct-hold applications that are more N3DS-compliant, although it is not yet possible to determine whether Nintendo will be used.

"Time-sharing multi-function glasses 3D stereoscopic display"

Time Multi-function glasses 3D stereoscopic display is on the same screen, each cut half the time to alternately display (tick) left and right two-eye screen (multirole) to achieve the 3D stereoscopic display effect, so it is called "time-sharing multi-function".

˙ directional backlight time-sharing 3D stereoscopic display

The directional backlight time-of-use 3D stereoscopic display is a way to achieve stereoscopic display effect by means of a directional backlight film paired with left and right backlit light source, and a high-speed alternate way to display different images to the left and right eye respectively. Because the directional backlight film can control the direction of light injection, the left and right images can be projected into the left and right eye of the viewer.

When the backlight light source on the right side of the screen is lit, the light from the direction of the left eye is emitted through the directional backlight film to display the left eye screen. When the backlight light source on the left is on, the light in the direction of the right eye is emitted through the directional backlight film to display the right eye screen. By the high-speed alternating display of the left and right picture, the stereoscopic image can be displayed smoothly.

Because of the directional backlight mode using time-sharing multi-work, so each can be the full resolution of the Panel to display the screen, unlike the spatial multi-function can only be used to display the half of the resolution of the Panel screen. And as long as the left and right side of the backlight light source at the same time, you can switch to 2D display mode. However, since the left and right eye images are displayed in a directional manner, stereoscopic images can only be seen when viewed from the front of the screen and cannot be displayed when the screen rotates 90 degrees.

Directional backlight time-sharing 3D stereoscopic display product is still in the research and development stage.

˙ Depth-Fused 3D stereoscopic display (depth-fused 3D)

Deep Fusion 3D Stereoscopic display is the two-piece LCD panel before and after overlapping together, respectively, in front and back two LCD panels with different brightness display foreground and background image, with the depth of the body of the difference to show the field of effect.

Hitachi's deep-fusion 3D Stereoscopic display screen

Because the depth of the fusion is not like other ways to simulate two-eye parallax to create three-dimensional sense, but to make the picture really has the difference between the foreground and the background, so that the focus of the two eyes of the viewer will naturally fall in the picture position and feel the depth of field, so the eyes are less prone to fatigue when viewing. However, the angle offset is limited by the overlap of the front and rear view, so the angle of the suitable viewing is limited, and the need to overlap two LCD panels to form, so the larger the cost of large volume.

Deep-Fusion 3D stereoscopic display is not a multi-work method, the product has been a long time but the application level is limited.

Since the 3D stereoscopic display is highly entertaining, it has long been used in the entertainment industry, but due to the high cost of filming, production and broadcast, the coverage is limited. However, in recent years, the 3D display hardware and software technology gradually mature and popular, coupled with the film and home appliances manufacturers have planned a strong promotion, so since 2009 has become a hot topic.

The same is the entertainment industry, a ring of the game industry, the application of 3D stereoscopic display technology has been more than 20 years, from 1986 SEGA launched the "3d glasses", to 1987 Nintendo launched the "famicom 3D system",1995 Nintendo launched the "virtual boy",2 010 years SCE reservation through the System Software update support PS3 3D stereoscopic display function, until 2010 Nintendo scheduled to launch the "nintendo 3ds", can be said to be quite rich.

˙sega markiii/master system"3d Glasses (3D Glasses)"

SEGA in June 1986 in North America launched the SEGA MARKIII architecture with the new design of "sega Master system", and in the same year launched the first game history of 3D glasses peripheral "3d Glasses", the use of cable-connected LCD 3D stereo glasses, The SEGA MARKIII and the North American Master System must be connected via a card-type adapter, and a dedicated connection terminal is provided directly on the Japanese version of Master System.

SEGA 3D Glasses

There are 8 games that support SEGA 3D glasses:

˙ Eagle 3D (Blade Eagle 3-d_)

˙ "FireWire Action"

˙ "Maze Hunter 3D (Maze Hunter)"

˙ "Missile air defense 3D (missile Defense)"

˙ "Out Run"

˙ "Naval warfare (Poseidon Wars)"

˙ "Space Harry 3D (Harrier)"

˙ "Three-dimensional air combat 3D (Zaxxon)"

˙ Nintendo famicom"Stereo glasses (とびだせメガネ)"

In March 1987, the Get started SQUARE with the 7-brand DOG Original Group launched the 3D stereoscopic display 3D action shooting game "three-dimensional big battle (とびだせ masterpiece Stardust)" in the Red and white machine disk system, and with the game to send the attached red-blue color filter 3D Stereoscopic glasses "Stereo glasses (とびだせメガネ)".

"Three-dimensional big battle" game magnetic disc and stereo glasses

The composition of the game is very similar to the SEGA of "Space Harry", the use of the image of the deep Mercedes-Benz jumping 3D play, as long as the 3D mode and wear glasses, you can have three-dimensional level in the experience of high-speed Mercedes-Benz fun.

Because the use of low-cost red and blue color filter 3D stereoscopic display, so can be free to play with the game without additional purchase of glasses, in order to play as a selling point and support three-dimensional display of novelty features, launched at that time quite by the players attention.

˙ Nintendo famicom"famicom 3D Systems (Famicom 3D System)"

The Nintendo who loses the array, also in the SEGA 3D glasses came out in October 1987, the introduction of Famicom 3D Stereo glasses "famicom 3D system", the same is the use of cable-connected LCD 3D stereo glasses, through the plug-in Famicom peripheral expansion terminals of the adapter assembly With a strap-on head-mounted design.

Nintendo Famicom 3D System

There are 7 games that support the Famicom 3D system:

˙ Animal Science Park (アタックアニマル Gakuen)

˙ "Space Stereoscopic Warfare (コズミックイプシロン)"

˙ "JJ Big Battle (JJ)"

˙ Racing (ハイウェイスター)

˙ "Nintendo formula racer 2:3d cross-race (ファミコングランプリii 3dホットラリー)"

˙ "Space Stereoscopic Warfare (ファルシァ◇)"

˙ The Dark lord of the Shaolin Boxing (The Devil of the Shaolin Boxing dark)

˙ Nintendo "virtual boy"

The above 3D stereoscopic glasses are to purchase the surrounding way, and at that time the game machine completely does not have 3D drawing ability, can present the stereoscopic image only to have the level sense plane image, therefore the penetration rate and the support degree are not high.

In July 1995, Nintendo launched the first game console to truly support the 3D stereoscopic display, "virtual Boy (VB), developed by a minister of Nintendo, who has dominated the Game&watch and GB series of popular products, with a two-monitor design, Create a three-dimensional sense through two sets of monitors.

Virtual Boy

Virtual Boy uses a 32-bit microprocessor made by NEC to provide a certain amount of 3D drawing processing power. In order to overcome the high cost of dual-display design, Virtual Boy uses a unique red LED array scanning imaging, the left and right eye respectively configured 384 horizontally arranged red LED array, through 50 times per second of the mirror and each swing 224 times the red LED array, to constitute 384 x224 4-segment red-and-black stage images updated 50 times per second.

Although Virtual Boy provides a genuine 3D stereoscopic display, but because the red and black level of the monotonous picture does not appeal to consumers, compared to the same period of Playstation/sega Saturn is not pleasant, plus play when spectators can not be a glimpse at all, and there are rumors that Virtual boy has a negative impact on children's eyesight, so sales are poor, with only 19 games before and after a bow, is Nintendo's most ephemeral game console.

˙konami"solid eye"

KONAMI in December 2005, the PSP Card strategy game "alloy Equipment acid 2 (Metal gear acid 2)", and with the game with a special PSP with 3D stereo glasses "solid eye". The glasses are made of thin plate, with two lens holes attached, the PSP screen will be separated into two halves, when the player from the lens hole to view the screen, will be from the left and right two different images of the parallax generated three-dimensional, experience 3D stereoscopic game fun.

The game provides "alloy equipment 3: Survival battle" stereoscopic photo for players to collect appreciation, but also through the connection to download their own shooting of the battlefield photo, but also with the photo Idol magazine "sabra" Cooperation to provide sexy actress photo.

Example of 3D stereoscopic picture of "alloy equipment 4" cross-gaze method

Solid Eye adopts the double-lens parallel line-of-sight method mentioned above, but because the screen display area will become half when the 3D mode is turned on, and the eyes must be compact in front of the glasses, the interest is more than the practicality.

˙nvidia"3d vision"

NVIDIA, the PC graphics factory, was the first to publish 3D stereoscopic glasses "3d vision" for PC use at the end of 2008 and was launched in March 2009. With NVIDIA's solution for home GeForce series graphics and support from many PC game makers, players can enjoy the 3D stereoscopic display game.

3D Vision also uses the common liquid crystal 3D stereo glasses, through the USB interface of the infrared synchronous signal transmitter and PC graphics synchronization operation, paired with the monitor must support 120 times per second of the refresh rate to provide binocular stability of 60 images per second display, so for the graphics performance and display specifications There is a considerable demand.

Since 3D Vision can support 3D stereoscopic display from the driver, many of the previously launched PC games can get 3D stereoscopic display in place without needing to be updated. However, the 3D Vision set cost $199, already equivalent to the high-end graphics price, so sales are not big.

NVIDIA's follow-up with the GeForce GTX 400 series syncs with the "3d Vision surround" Technology, which supports 3 screens, provides 3-screen surround 3D stereoscopic display, but requires a higher level of hardware.

˙konami "Alloy Equipment Arcade"

3D stereoscopic display in the application of large-scale video games can be traced back to the age of 1980, as the large-scale video game machine can be tailored to the needs of the hardware, so including body sense frame, multi-screen display, 3D stereoscopic display and other applications can be said to be various, the recent more attention is KONAMI of the "alloy equipment Arcade (Metal Gear Arcade) ".

4-connected cockpit-style luxury frame

"Alloy Equipment Arcade" is the launch of the June 2008 operation of PS3 connected action game "alloy equipment Online (Metal gear online)" as the basis of the production, inherited PS3 version of the basic system, and added 3D stereoscopic display, 5.1-channel surround sound surround sound, Light gun controller + head connected body feeling operation and other new gameplay.

"Alloy equipment Arcade" uses polarized 3D stereoscopic glasses, in addition to providing 3D stereoscopic display function (can be closed), but also configured to detect the head movement of the device, so that the player can control the role of the head point of view.

˙sce"playstation 3"

The promotion of Sony, 3D spared no effort, in January 2009 at the Consumer Electronics Show (CES), the first to showcase the use of PS3 with polarizing 3D LCD TV to provide 3D gaming entertainment applications, followed by the February 2009 Taipei International Games Show the same combination. The business strategy statement held in November 2009 is a formal confirmation that all PS3 can support the 3D stereoscopic display Multimedia game entertainment function through the system Software update mode.

SCE also indicated that it will devote full effort to the development of 3D stereoscopic display game, although the "Sports Car romantic Tour 5 preface" and "Major League Baseball 09" appeared in the technology show, but has not yet determined whether formally support.

˙ Nintendo "nintendo 3ds"

March 23, 2010, Nintendo Flash release will be launched by the end of March 2011 to support the open-hole 3D stereoscopic display of the NDS successor "nintendo 3DS (N3DS, temporary)", but the text press release only mentions "Support naked 3D stereoscopic display" and "compatible with the existing NDS /NDSi Software "These two features, the rest of the details remain a mystery.

N3DS spoof scenario Diagram

NDS has become Nintendo has been the best-selling game consoles, all circles have been very concerned about the introduction of more than 5 years of NDS successor machine species of the trouble, so this n3ds published immediately aroused enthusiastic echo. Although the information published is extremely limited, it leaves more room for imagination. The open-hole 3D stereoscopic display technology which has been in existence for many years also caught the n3ds of the car, instantly became the focus of attention.

Manufacturers, including Sharp and Hitachi, who have been actively developing the 3D stereoscopic display technology, are also following the N3DS to publish their own new products, such as Sharp's high-definition glasses 3D LCD screen with integrated touch function, Hitachi publishes an eye-catching 3D LCD panel that can reduce eyestrain, all using liquid crystal vision The design of the difference barrier type.

Since Nintendo has been using Sharp's LCD screens for a long time since 1980, the likelihood of n3ds using sharp products is quite high, but Nintendo and Sharp both are lipped and are not yet confirmed.

As the successor of the N3DS has been determined to be compatible with the existing NDS/NDSI software, is expected to be able to successfully inherit the vast expanse of NDS, and the newly added open-hole 3D stereoscopic display function can bring the game what kind of change? Are there other new features that have shocked the community? All the mysteries will be announced at the E3 show in mid-June ...
