Ultra-polar screen era comes to the ultimate development of mobile screen

1974, the world's first mobile phone was born, but the phone does not have a screen, it is easy to make the wrong phone. 1983, the world's first screen phone was born. After entering the 21st century, mobile phones began to play an important role in our lives. The size of the phone is getting smaller, but the screen is getting bigger.

Screen as the most important, display output devices, from the original monochrome LCD display screen, to STN, CSTN display technology, and then to the TFT display, display technology almost witnessed the development of the mobile phone industry. It is such a small display device, but contains unlimited cutting-edge technology and the crystallization of human wisdom.

Mobile screen History Video

CSTN Display

CSTN is an acronym for Color STN, an STN upgraded product that is higher than the brightness and contrast of STN. Generally adopt the transmission type illumination way. When you use this type of cell phone, you will usually find a backlight on the screen, so this screen in normal and dark light environment display better than STN, CSTN is the principle of a traditional monochrome stn LCD display on a color filter, and the monochrome display matrix of each pixel into three sub pixels, The color screen can be displayed by using color filter to display red, green and blue colors. Unlike TFT, STN is passive LCD display, the highest can display 65K color. But slow response is its Achilles ' heel, and that's why many mobile phones that use this kind of screen look very slow, actually from the sluggish screen response speed.

SLCD Display

Representative Models: HTC G7 (Desire), HTC G11 (Incredible S), HTC Mozart, HTC G14 (Sensation)

SLCD is the abbreviation of splice Liquid Crystal display in English, namely splicing the special LCD screen. SLCD is a high-end derivative of the LCD, using the world's most advanced industrial-grade LCD panels, the service life of up to 60,000 hours. Comparison AMOLED,SLCD display effect is more bright, color richer, but the color reduction effect is poor, strong light mode, poor visibility, power-saving performance is not as good as the luminous amoled.

ASV Display

Representative Model: Charm M9/MX, millet mobile phone

ASV itself is not a screen material, but a technique for improving image quality. The use of ASV Technology LCD panel is designed for light reflection and transmission problems, it by adding several layers of film with special chemical coating on the screen surface of the external light processing, on the one hand, refracted into different proportions, so that reflected light to change direction and cancel each other, On the other hand, the maximum absorption of foreign light, change the wavelength and reflection of light transmission.
At present, ASV technology is almost exclusive monopoly by Sharp, the first to introduce domestic ASV is the M9 of the family, the charm of the family with the same resolution as IPhone4 640x960. The ASV screen improves the traditional TFT screen's visual angle, as well as the response speed, reduces the spacing between the particles on the LCD panel, increases the liquid crystal particle glazing circle, and makes the color display and contrast more outstanding. The lateral visual angle is slightly less than the top part of the high-end technology, and in the side of the screen easy to produce a partial color.
Using the ASV screen, the Phantom MX has the advantage of leading iphone in color, but the visual angle is not as iphone4s,ppi as iphone.

Nova Display

Representative model: LG Optimus Black

Nova is a new screen display technology that comes with the launch of LG P970-black. According to LG officials, NOVA display can reach 700 in brightness. Above the iphone 4 screen brightness of 530 guineas. It's the brightest screen on the market right now.
No matter in indoor light or outdoor strong light, can show a clear effect. In the same indoor environment, the Nova display can reduce energy consumption by 50% compared with a normal LCD screen. Since White is currently the most popular web browsing color scheme, the Nova screen can save half the power consumption of a AMOLED screen when the phone displays a full-screen screen. But in addition to high brightness and power saving, the Nova screen is not too bright, cost-effective.
