Light guide plate forming production method

Abstract

The invention provides a light guide plate forming production method. The light guide plate forming production method comprises the following steps of carving an original plate; performance testing; mold manufacturing, and specifically filling light guide dots with corrosion-resistant material, and forming a corrosion-resistant block after curing; connecting one side of the corrosion-resistant block fixedly with an etching plate to form a primary template; etching the primary template to obtain a secondary template; electroplating the top surface of the secondary template to obtain a metal film, wherein the back surface of the metal film clings to the secondary template; separating the secondary template from the metal film, and molding on the back surface of the metal film to obtain a mold core; forming a reflecting layer, and injecting reflecting molten metal into the lower die cavity; forming a body; forming a protective film; eliminating bright edges, and forming a frosting layer through sand blasting; removing the film; and mass production. According to the method, high consistency between the light guide dots of the finished light guide plate obtained by mass production and the original light guide dots can be ensured, and the production efficiency can be improved; the light guide plate is integrally formed to obtain the reflecting layer, and production time can be effectively shortened; and the frosting layer obtained by coarsening can effectively improve the light emitting uniformity.

Description

technical field [0001] The invention relates to the production and processing of the light guide plate, and specifically discloses a molding production method of the light guide plate. Background technique [0002] The light guide plate can diffuse the light incident from the end surface of the light guide plate to various angles, and then break the reflection condition and emit from the front of the light guide plate. The light guide plate is the core component of the surface emitting module, which is often used in displays, lamps and other products. [0003] In the prior art, light guide plates are all obtained by printing light guide dots on the back of glass, optical grade acrylic, etc. The light guide dots can only be engraved or printed after the substrate is formed, and the production efficiency is low, and each time the dots are printed or engraved, high-precision processing is required, which is difficult to process and high in production cost.

[0003] In the prior art, light guide plates are all obtained by printing light guide dots on the back of glass, optical grade acrylic, etc. The light guide dots can only be engraved or printed after the substrate is formed. The production efficiency is low, and each time the dots are printed or engraved, high-precision processing is required, which is difficult to process and high in production costs.
