Problems solved by technology

However, since the adjustment of the dot matrix has no rules at all, it must be manually adjusted according to the actual test results of the formed light guide plate
Therefore, this method often requires repeated processing of the mold workpieces required for molding to achieve a satisfactory effect, and the cost of mold production is very high.

Embodiment

[0015] A mold for improving the uniformity of light transmission of a light guide plate, the structure of which is as follows figure 1 As shown, on the surface of the molded light guide plate mold workpiece 1, the area of ​​the light-transmitting surface that needs to be molded is set with a lattice 2, and a layer of skin texture 3 is further machined in the area of ​​the lattice 2 to form the transparent surface of the light guide plate mold workpiece 1. In the light area, the required lattice 2 needs to be processed first, and then the skin texture 3 is processed, so that the light transmission of the formed light guide plate is more uniform. Lattice 2 plays the role of preliminary refraction of light, and dermatoglyph 3 refracts the light that has been refracted by lattice 2. The uniformity of the light after two refractions is much higher than that of pure The refraction effect of the lattice 2, therefore, the light transmission uniformity of the light guide plate processe...

Abstract

The invention relates to a mold for improving the transmission uniformity of a light guide plate. On the surface of a molded light guide plate mold workpiece, an area where a transmission surface is required to be formed is provided with a dot matrix; and the dot matrix area is provided with a layer of patterns, so that light transmission of the molded light guide plate is more uniform. Compared with the prior art, the mold has the advantages: the surface where the dot matrix is formed is provided with a layer of ordinary pattern surface, and the processing technic of the patterns is very easy, so that the light transmission of the molded light guide plate is more uniform, and the requirement of transmission uniformity on a product is met easily.

Description

technical field [0001] The invention relates to a light-transmitting process for a light-guiding plate, in particular to a mold for improving the light-transmitting uniformity of the light-guiding plate. Background technique [0002] At present, many display devices rely on light guide plates to guide the propagation of light, and the quality of light transmission of the light guide plates directly affects the success or failure of the entire display device. Among the various factors that affect the light transmission of the light guide plate, the uniformity of light transmission is a very important part. How to better improve the light transmittance uniformity of the light guide plate has always been a difficult problem in the industry. In response to this problem, in the industry, it is generally used to adjust the density of the lattice to achieve uniform light transmission of the light guide plate. However, since there is no law in the adjustment of the lattice, it mus...
