LED light guide plate



The role of the light guide plate is to guide the scattering direction of light to improve the brightness of the panel and ensure the uniformity of the panel brightness. The good 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 It is one of the key technologies.

The light guide plate is made by using the injection molding method to press propylene into a plate with a smooth surface. Then, using a material with high reflection and non-light absorption, the diffusion point is printed on the bottom surface of the light guide plate by screen printing. The cold cathode fluorescent lamp is located on the light guide plate. On the thick end of the side, the light emitted by the cold cathode tube is transmitted to the thin end by reflection. When the light hits the diffusion point, the reflected light will diffuse to various angles, and then destroy the reflection conditions and shoot out from the front of the light guide plate.

Sparse and dense diffusion points of different sizes can make the light guide plate 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.

The light guide plate can be divided into printing type and non-printing type according to the different process flow. The printing type is to use a high reflectivity and non-light-absorbing material on the acrylic plate. The bottom surface of the light guide plate is printed with a circle or a square by screen printing. The spread point. The non-printing type uses a precision mold to make the light guide plate in the injection molding process, adding a small amount of granular materials with different refractive indexes to the acrylic material to directly form densely distributed tiny bumps, which act like dots.

The printing method is not as effective as the non-printing method. The non-printing method has excellent effect, small number of users, high speed and high efficiency, but the technical threshold is very high. It is necessary to master precision injection molding, precision molds, optics and other technologies. At present, there are three companies in the world that are proficient in this, and the market is basically controlled by these three. According to the statistics of Taiwan IEK in 2002, the market shares are Asahi Kasei (35%), Mitsubishi (25%), Kuraray (18%), and the rest.

Most of them are light guide plates produced by printing methods. At the same time, Asahi Kasei is also the largest provider of organic glass materials, occupying more than 50% of the market. And Mitsubishi is the best in the world in terms of plexiglass production and processing technology. At present, most domestic manufacturers still use printed light guide plates as light guide components. Printed light guide plates have the advantages of low development cost and fast production. Non-printed light guide plates are more technically difficult, but they have excellent brightness.
