Principles and structure of the Character oled character display 20x4

Tsingtek lcd display 20x4 the liquid crystal liquid crystal is a liquid capable of flowing like a fortune crystal material chemical properties of crystals . Alignment of liquid crystal molecules have a certain order, arrangement of liquid crystal molecules will change in the role of outside plant , thus affecting his chemical properties.
    LCD screen is composed of two parallel thin glass plate , the distance between the two glass is very small , is divided into small cells filled the LCD . LCD panel itself does not light , he passed backlight display lcd 20x4 screen LCD screen is lit up . Advantages of graphic lcd 128x64 screen is small, light weight, large area display , image stabilization, no radiation, low power consumption and environmental protection features . Compared with the liquid crystal display, a CRT power consumption of the liquid crystal display only one-third .
    TFT LCD screen, the abbreviation thin film transistor liquid crystal screen is the top material belonging to an active matrix type liquid crystal screen , the back has a special lamp, you can take the initiative to each individual pixel on the screen to control, which is what we said active matrix TFT, his reaction is faster , viewing angle , color saturation. TFT LCD screen by the arrangement has a memory , so it will not restore the status quo ante in the current disappears immediately and effectively improves the ability to play a dynamic picture .
