Abstract

The invention relates to the field of light guide plates of display backlight units, and especially relates to a nickel alloy light guide plate cavity manufactured through using an LIGA technology. The cavity comprises a substrate, a photoresistive film coated on the substrate and an electroforming nickel layer electroform-deposited on the surface and the periphery of the photoresistive film, the photoresistive film is provided with a photoresistive pattern, and the electroforming nickel layer is provided with a plurality of uniform micropores; and the photoresistive pattern is consistent with the micropores in shape. According to the invention, light guide plates manufactured from the nickel alloy light guide plate cavity manufactured through using the LIGA technology have the advantages of high brightness, high uniformity, good surface roughness, realization of microscopic three-dimensional structure, and rapid production period; and a light cover design is utilized to design different patterns to manufacture micro lens (having arbitrary shapes, such as oval, long sector and the like) with different micro-structures, so different light guide effects are obtained.

Description

technical field [0001] The invention relates to the field of light guide plates of display backlight modules, in particular to a nickel alloy light guide plate mold core manufactured by LIGA technology. Background technique [0002] The uniformity and luminance of the display are important indicators for evaluating the display. This characteristic is determined by the backlight module. The light guide plate is the medium through which the light source propagates in the backlight module. The shape and material of the light guide plate are the key factors for the luminance and uniformity of the light source. . With the increasing requirements for display quality, the scale requirements of the optical micro-features of the light guide plate are becoming more and more fine. At present, the light guide plate in the large-size LCD backlight module uses dot printing, precision machining and electro-jet processing for the mold making part. Among them, the light guide plate pattern ...
