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, dot matrix 2 is processed in the region of the light-transmitting surface to be formed, and a layer of skin texture 3 is reprocessed in the dot matrix 2 area, and the light guide plate mold workpiece 1 is formed. The light area needs to process the required dot matrix 2 first, and then process the skin pattern 3, so that the light transmission of the formed light guide plate is more uniform. The dot matrix 2 plays the role of preliminary refraction of the light, and the striae 3 refracts the light that has been refracted by the dot matrix 2 again. The uniformity of the light after two refractions is much higher than that of the simple The refraction effect of lattice 2, therefore, the uniformity of light transmission of the light guide plate processed by using the mold c...

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 transmission process of a light guide plate, in particular to a mold for improving the uniformity of light transmission of a light guide plate. Background technique [0002] At present, many display devices rely on light guide plates to guide the transmission of light, and the quality of light transmission through the light guide plates directly affects the success or failure of the entire display device. Among the various factors affecting the light transmission of the light guide plate, the uniformity of light transmission is a very important part. How to better improve the uniformity of light transmission of the light guide plate has always been a problem that plagues the industry. In response to this problem, in the industry, it is generally used to adjust the density of the dot matrix to control the uniform light transmission of the light guide plate. However, since the adjustment of the dot matrix has no rules a...
