LCD mainly includes TFT, UFB, TFD, STN and other types of LCD. The structure of LCD is to place liquid crystal in two parallel glasses. There are many vertical and horizontal small wires between the two glasses. The direction of rod crystal molecules is controlled by power on, and the light is refracted to produce a picture.   High brightness, The higher the brightness value of the array LCD, the brighter the picture will be without blurring. Advanced display can display clearer and higher brightness product features. We rely on polarization filters and light itself. With the practice of natural light in all corners of the world, a series of liquid crystal filters must be parallel.   The higher the contrast, the more colorful and saturated the color will be, and the higher the plane will be. On the contrary, the color change is low, the color display is poor, the image will be flattened, and the color change value is different, even higher. Compared with CRT imager, LCD dot matrix LCD display has the advantages of zero radiation, low power consumption, small heat dissipation, small volume, accurate image recovery and high character visualization.   The view of “big view” simply means that the view in front of the screen can be seen the larger the sight distance, the easier it will be; As long as the viewer changes the viewing position slightly, the picture may become blurred.

What are the characteristics of LCD?   Thin fuselage, space saving: Compared with the bulky CRT display, the LCD display only has one third of its space. Power saving, no high temperature: It belongs to low power consumption products, cannot burn completely, relative to CRT display, because imaging technology inevitably produce high temperature. No radiation, good for health: LCD is completely radiation-free, which is a good news for people who work in front of the computer all day. Soft screen does not hurt the eyes: Different from CRT technology, LCD screen will not flash, it can reduce the screen damage to the eyes, and the eyes are not easy to fatigue.
