Description

Liquid crystal screen

Technical Field

The utility model relates to a liquid crystal display field, more specifically say, relate to a liquid crystal screen.

Background

The liquid crystal screen uses liquid crystal material as basic component, and the liquid crystal material is filled between two parallel plates, and the arrangement state of internal partial molecules of liquid crystal material can be changed by means of voltage so as to attain the goal of shading light and transmitting light, and can display colour image. The lcd panel has low power consumption, and is therefore popular with engineers and suitable for electronic devices using batteries.

The liquid crystal panel is one of the most important and most costly components of the liquid crystal panel. Although the color effect of a liquid crystal display is not ultimately determined by the liquid crystal panel only which component (the IC chip of the display is also critical), it is a very important part.

The liquid crystal panel mainly comprises the following eight parts:

1. backlight (or backlight module):

since the liquid crystal molecules themselves cannot emit light, in order to realize a picture, the liquid crystal display needs a special light source to provide light, and then different colors are generated by the deflection of the liquid crystal molecules. And the backlight functions to provide light energy. The prior liquid crystal screen adopts a cold cathode ray tube which is named as CCFL, the light emitting principle of the cold cathode ray tube is almost the same as that of a fluorescent lamp, and the new liquid crystal screen adopts an LED backlight source which is more energy-saving and long-life. After the lamp tube (or LED) emits light, the light is distributed to each part through the light guide plate, and all the directions of the light are concentrated to the liquid crystal molecules through the reflecting plate on the back surface. Finally, light is uniformly distributed through the prism sheet and the diffusion plate, and the situations that the central brightness is too high and the peripheral brightness is too low are avoided.

2. Two upper and lower polaroids:

the polarizer functions to allow light to pass in a single direction.

3. Two glass substrates of upper and lower layers:

the glass substrate is not only simple as two pieces of glass, but also has a groove structure on the inner side, and an alignment film is attached to the groove structure, so that liquid crystal molecules can be arranged regularly along the groove. TFT thin film transistor and color filter are adhered on two sides of the upper and lower layers of glass.

4. ITO transparent conductive layer:

its function is to provide a conductive path, divided into a pixel electrode (P-stage) and a common electrode (M-stage).

5. Thin film transistors (which we often refer to as TFTs):

the TFT-LCD, which is often referred to as a TFT, functions like a switch, and the TFT can control a signal voltage on an IC control circuit and transfer it to liquid crystal molecules, determining the amount of angle of deflection of the liquid crystal molecules, and thus is an important component.

6. Liquid crystal molecular layer:

it is the most important element for changing the polarization state of light, and the arrangement and polarization state are determined by electric force and elastic force.

7. Color filter:

the light deflected by the liquid crystal molecules can only display different gray scales but cannot provide three primary colors of red, green and blue (RGB), and the color filter consists of RGB filters, and each color and brightness can be adjusted by mixing the RGB filters. Each pixel in the liquid crystal panel is composed of 3 dots of red, green and blue, and each dot of each color has a different gray scale variation.

8. Frame glue;

it is exactly let two-layer glass substrate can be firm sticking together about in the liquid crystal display panel to with whole internal system and external "isolated", prevent that the dust from getting into the influence color effect.

The structure described above is the structure of the panel used by most of the lcd tvs and displays on the market, and some special products may use different accessories, but the overall architecture and the working principle are not greatly different; although the liquid crystal screen has many advantages, the service life of the liquid crystal screen is much shorter than that of a CRT, the aging speed is much faster, extra attention is paid when the liquid crystal screen is used usually, the protective film of the liquid crystal screen can effectively protect the chemical coating on the outer layer of the screen, the outermost coating cannot be oxidized prematurely, the protective film is torn off when a user uses the liquid crystal screen to pursue the optimal display effect, then the liquid crystal screen loses the protection of the protective film, the aging speed is accelerated, and meanwhile, dust, water stain or foreign matters are easy to adhere to the screen to influence the light transmittance of the liquid crystal screen.
