Abstract

The invention relates to a manufacturing method and application of a light guide plate die core component. A first photo-resistance layer and a second photo-resistance layer are formed on a first base material and a second base material respectively, and then a light-guiding pattern and a spreading pattern are formed in the first photo-resistance layer and the second photo-resistance layer respectively. The first female die and a second female die are obtained after the steps of conductive layer coating, electroforming and stripping. The surface of the first female can be provided with the a pattern corresponding to the light-guiding pattern of the first photo-resistance layer, and the surface of the second female die can be provided with a pattern corresponding to the spreading pattern of the second photo-resistance layer. In addition, the invention also provides a combined type light guide plate, the light guide plate die core can be manufactured into a combined type light guide plate with high translucency and the light-guiding and spreading functions, so that a combined type light guide plate capable of replacing a spreading piece, a brightening piece and / or a reflecting piece can be manufactured.

Description

technical field [0001] The invention relates to a manufacturing method of a mold core component of a light guide plate. In addition, the present invention also relates to a manufacturing method of a composite light guide plate, especially a composite light guide plate with high light transmittance and functions of light guide and diffusion. Background technique [0002] At present, the development trend of electronic products is towards light, thin, small and multi-functional. Taking thin-film liquid crystal display as an example, thinness, light weight, high brightness and light uniformity are all very important mainstream demands in the current market. How to develop and design various new types of backlight modules and light guide plates for domestic manufacturers to enhance their competitiveness with manufacturers from other countries in the international market is the direction and important topic of development in related fields. [0003] According to the prior art, m...
