Graphic LCD Display Basic Structure

- Oct 13, 2017 -

The highlighted LCD screen is structurally a flat panel display part. Its basic structure is flat-shaped. Graphic LCD Display Typical highlights LCD basic structure: it mainly by the front and back Polarizer, before and after the Ito conductive glass, sealing edge and liquid crystal and other major components. Of course, Graphic LCD Display different types of highlighted LCD parts may be different, Graphic LCD Display such as: Phase Variant, PDLC, multi-steady-state highlight LCD screen without polarizer, the active matrix-type highlight LCD on the substrate on the production of active matrix circuit, etc., but all the highlighted LCD screen can be considered to be two-piece lithography with transparent conductive electrode substrate, Holding a liquid crystal layer, Graphic LCD Display sealed into a flat box, sometimes on the outside surface may be affixed with a polarizer and so on.

The liquid crystal material is the main body of the highlight LCD screen. Unlike liquid crystal materials used in different devices, liquid crystal materials are mostly made of several or even more than 10 kinds of monomer liquid crystal materials. Each liquid crystal material has its own fixed clear highlight TL and crystallization point ts. Graphic LCD Display Therefore, it is also required that each type of bright LCD screen must be used and stored in a certain temperature range between TS--TL, if the use or preservation of temperature is too low, crystallization will destroy the highlight of the LCD screen orientation layer, and the temperature is too high, Graphic LCD Display liquid crystal will lose liquid crystal State, also lost the function of LCD

This is a very flat surface of the float production of thin glass film. Surface evaporation has a layer of In2o3 and SiO2 transparent conductive layer, namely Ito film layer. Transparent conductive graphics are made by photoetching, which are composed of pixel graphics and external line graphics. Therefore, Graphic LCD Display the external line can not carry out traditional solder, only through conductive rubber strips or conductive tape and so on to connect. If scratched, cut or corroded, it will cause the device to scrap.

Polarizer is also called polarizer, made of plastic film material. Coated with a layer of optical pressure-sensitive adhesive, can be affixed to the surface of the LCD box. Graphic LCD Display The front polarizer surface also has a protective film, the use should be removed, polarizer afraid of high temperature, high humidity, in high temperature and humidity conditions will make it depolarization or foaming.

A matching film is arranged on two glass substrates, so the liquid crystal will be matched along the groove, the liquid crystal bar molecule with dipole moment changes in the arrangement state of the external electric field, so that the light of the liquid crystal display is modulated, Graphic LCD Display which shows the display effect of the bright and dark or through and not through. Each display pixel in the highlighted LCD can be controlled independently by the electric field, Graphic LCD Display and different display pixels can form different characters, numbers and graphs on the display according to the command of the control signal. Therefore, the display of the required electric field and control of the combination of display pixels to become a liquid crystal display driver and LCD controller functions.
