LCD is the most important channel for human-computer interaction. LCD not only displays text information but also waveform information. Therefore, it is essential to compile a complete set of function libraries, it should include a series of functions such as displaying ASCII codes, strings, integer numbers, floating point numbers, Chinese characters, painting points, and draw lines.
The establishment of upper-layer functions is in
Q: What is LCD?The original text of the LCD display is liquid crystal display, which consists of the first letter of each word. The Chinese name is "LCD flat display" or "LCD display 」. The working principle is to use the physical characteristics of the liquid crystal: The arrangement becomes orderly during power-on, s
display. This has also been introduced before (see this site).and LCD display can achieve large-screen, high-precision, with the ability to achieve a large range of color performance, as a high-quality display has been widely used. Moreover, the LCD screen manufacturing technology is very mature, before long, China's production will become the first. However, liquid crystals are always fluid, must be ordered, so, with the development of extremely thi

What is liquid crystal:
Liquid crystal is a kind of polymer material, because of its special physical, chemical, optical characteristics, 20th cent
Wiki Wikipedia on the https://en.wikipedia.org/wiki/Liquid_crystal, applications of Liquid crystals section, a lot of English can not understand, only know the image of a general meaning. The use of polarizing film (high school physics to talk about the nature of light waves) liquid crystal in the electric field changes, when the power is not able to let light wa
If you have a laptop or a desktop LCD on hand, you must be pampering, right? But for that faint liquid crystal display, have you taken good care of it? Do you often touch the lovely blue screen with your hands? In fact, we often do not pay attention to the use of LCD monitor maintenance. Although the service life of LCD is up to more than 10 years, it is very important to keep careful maintenance at ordinar

Liquid crystal display with thin fuselage, save space; do not produce high temperature, low radiation, good health, the screen is not to hurt the advantages of the eye is now widely used, that everyone on the life of the liquid crystal display is not understand how long, the following small series to introduce the life
First, Color chapter(color, brightness, contrast, angle, color temperature)
First special emphasis: for any display (crt/lcd/...). ), color is always the first! The authenticity and softness of color display is the most direct feeling to the eye!
As for the brightness contrast and even the perspective of why to fall to the color section, the following will have the answer.
"Good liquid crystal display co
Inferior liquid crystal Protective film affixed to the screen, there will be a lot of bubbles, directly affect your vision. And the wear resistance is not high, the use of liquid crystal Protective film is very short. The liquid crystal
Identification of refurbished liquid crystal displays: Attention to check the appearance of the use of traces
Even if the profiteers means again superb, generally refurbished LCD display will also leave some used traces. With a closer look at the vertices of the display's border, you'll find some places with wear. Especially under the monitor base, because has been used for some time, the bottom will certa
of view, the better the viewing angle and the more applicability of the LCD display.
Because everyone's eyesight is different, so we use contrast, the greater the contrast in the maximum visual angle, the better. At present, most of the products in the market visual angle of more than 120 degrees, some products reached more than 170 degrees. What needs to be said is that in different measurements, the visual angle of the nominal value is also different, because the display manufacturers usuall
It is well known that the quality of a liquid crystal display first depends on its panel, because the quality of the panel directly affects the viewing effect of the screen, and the price of the LCD panel to account for the entire display cost more than 70%, is the main factor affecting the cost of LCD, so to choose a good liquid
Water ripple problems often occur when using a flat panel monitor. Liquid crystal display of the so-called water ripple problem, refers to the screen of dark wave interference in a form, to the user feel like a ripple on the water. Some friends said that even if the LCD has just bought water ripple phenomenon, the seller does not give a warranty or replacement.
In fact, most of the water ripple phenomeno
One, LCD panel is the largest cost
As we all know, the cost of the LCD panel itself is the most important part of the liquid crystal display. We take the market mainstream 19-inch widescreen LCD display For example, the latest updated international LCD supply price, 19-inch widescreen TN panel price of 122 U.S. dollars, relative to the 19-inch international LCD terminal price of 205 U.S. dollars, the calcu
1. Display machine without powerThis is a very simple fault, the general LCD display extension inside the power supply and external power supply two, outside the common some.Regardless of that power supply, its structure is much simpler than the CRT monitor's power supply, and the vulnerability is generally small components, such as insurance tubes, input inductors, switching tubes, voltage regulators and so on. Relatively rare failure is caused by the motherboard CPU power does not start, this
to wipe the LCD screen, it is easy to scratch the "squeamish" LCD screen. For the first type of dust, we can use Buckskin on the LCD panel gently wipe, can generally choose high-grade glasses cloth, but the effect is not the best. Fingerprints and oil stains are not as easy to clear as the former.
Misunderstanding two, clean the LCD screen with water. The use of water, liquid very easy to drop into the liquid
Screen highlights are generally refers to the LCD display can not repair the single color point. The crystal surface of the liquid crystal display is a whole cutting lens, in the process if there is a slight vibration or dust fall into the crystal structure, then this bright spot will be produced, and can not be repair
Now, most of our friends choose liquid crystal display, brand machine not to mention, the basic is 100% LCD configuration, therefore, it is necessary for everyone to introduce the best way to set the LCD display, including brightness, contrast, color temperature, resolution, geometric parameters of these basic parameters adjustment, come on, let us healthier, More comfortable using a flat panel monitor!

The meaning of dynamic contrast degree of liquid crystal display
Dynamic contrast refers to the contrast values measured by a liquid crystal display under certain circumstances, such as each area of the screen, and the contrast value of the region with the largest contrast as the contrast parameter of the product. LCD
