Liquid crystal display, or LCD (Liquid Crystal Display), is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of a light source or reflector. Liquid crystal displays have very low power consumption, so they are highly favored by engineers and are suitable for electronic devices that use batteries. Its main principle is to stimulate the liquid crystal molecules to produce dots, lines, and surfaces with the back light tube to form a picture. The light guide plate of the liquid crystal display is set according to the size of the display.

The function of the round acrylic light guide plate is to guide the scattering direction of the light to improve the brightness of the panel and to ensure the uniformity of the brightness of the panel. The quality of the light guide plate has a great influence on the backlight plate. Therefore, the design and manufacture of the light guide plate in the edge-lit backlight plate is one of the key technologies. The round acrylic light guide plate is made by using injection molding to press propylene into a plate with a smooth surface. Then, using a material with high reflection and non-light absorption, the bottom surface of the light guide plate is printed with diffusion points by screen printing. The CCFL or LED light-bar is located on the side of the light guide plate, and the light emitted by it is guided into the light guide plate by reflection. When the light hits the diffusion point, the reflected light will diffuse to various angles, and then it will destroy the reflection condition and shoot out from the front of the light guide plate. Utilizing various sparse and dense diffusion points of different sizes, the light guide plate can emit light evenly. The purpose of the reflective plate is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use.
LCD light guide plates can be classified according to different standards:
1) According to different shapes, it can be divided into flat plate, wedge plate and light guide plate with complex structure. The thickness of the flat light guide plate is constant, and is often used in small-size designs. The thickness of the wedge-shaped light guide plate changes linearly. Its advantages are low cost, light weight, and light source modulation.
2) According to the different production methods of light guide dots, it can be divided into printed light guide plate and non-printed light guide plate.
3) According to different light incident methods, it can be divided into edge light guide plate and direct light guide plate.
4) According to different manufacturing methods, it can be divided into injection molding light guide plate and cutting molding light guide plate.
