Because the printing network has poor uniformity of light, the processing is time-consuming, and it is revealed that the Chinese people are coated with a photoresist layer, and then Then, in the mold, the nickel-plated light guide plate can be formed and exposed, and the above methods are not in the technical field. The backlight module, the special purpose private design and the manufacturing method thereof are applied to the backlight module as the backlight module. The key components of the low-cost market demand, in order to maintain the manufacturing method of the light guide plate is subject to the research of the relevant industry. The light guide plate 1 is used to transmit the light from the source k to the light guide plate 10. At the end, the mesh point i 3 of the bottom surface 1 1 destroys the total reflection to make the front surface of the light plate 1 2 , and the manufacturing method of the conventional light guide plate is directly printed on the light guide plate to form the dot particles which are not fine enough and the ink viscosity is not easy to control. It will make it difficult to control the quality uniformity, and it is not a one-time molding, so it does not meet the demand for high mass production; and another manufacturing method, the national publication No. 5 1 4 7 6 6 patent, which precedes a plane After the photoresist is exposed and developed by the photoresist, a layer of copper crystal electroforming is used to electroform the surface of the copper seed crystal. After the nickel mold is separated from the planar substrate, the copper crystal seed is etched and removed, and the mold is removed. Ren, finally, by forming the backlight by the mold, but because the mold is manufactured through many processes (for example, electroforming, etc.) and the mold is not easy to modify; therefore, the use of the method to achieve high productivity, process simplification and Producing better optics
