LCD monitors how much you know

The liquid crystal display device (B CD) is a new display device. Since its inception in 1968, the speed of its development, the wide range of applications, have been far more than other light-emitting display devices.
Technical characteristics:
The liquid crystal is between the intermediate between the solid and liquid substances.экран lcd
General situation, it is the same and the liquid can flow, but different in different directions on its optical properties, showing similar to the nature of the crystals, so called of such substances is a liquid crystal. The use of liquid crystal electro-optic effect is made ​​into a display is LCD monitor.
Commonly used TN type liquid crystal display device has the following advantages:
(1) low operating voltage (2-6V), the match with CMOS circuits for micro-power (1μW/Cm2).QVGA LCD
(2) soft, clear handwriting; not afraid glare erosion, light, the stronger the greater the contrast, the better the effect. The small size, light weight, flat type.
(3) design and production process is simple. The size of the device could have been done, also can be made ​​very small; display content is displayed in the same plane can be done, and can also be less, and display the word operators can be designed to be nice.
(4) high reliability, long life, low-cost.
