Laser processing process for light guide plate net points

Abstract

The invention relates to the technical field of light guide plate processes, and discloses a laser processing process for light guide plate net points. The laser processing process for the light guideplate net points comprises the following steps: a two-dimensional plane coordinate is built on a light guide plate to be processed; a processing area in a plane is determined; line and row arrangement densities of the processing area are determined; laser energy values needed by processing of all processing net points in the processing area are determined, that is, processing laser pulse numbersneeded by multiple processing net points are firstly determined, and laser pulse numbers needed by all processing net points are obtained through a curve fitting mode; and finally, the processing is performed. Automatic arrangement of all the processing net points in the processing area is realized through computer software; in the whole process, the automatic integration degree is high, the manual operations are few, and the process is simple; the light guide performance of the produced light guide plate is excellent; the delivery yield is higher; and the production requirements can be met.

Description

technical field [0001] The invention relates to the technical field of light guide plate technology, in particular to a laser processing technique for dots of a light guide plate. Background technique [0002] The light guide plate is a light guide member that uses a high-tech material with high reflectivity and no light absorption to print light guide points on the bottom of the optical grade acrylic plate. The principle of light guide is mainly to use the optical grade acrylic plate to absorb light. The light makes the light stay on the surface of the plate. When the light hits the light guide point, through various light guide points of different densities and sizes, the reflected light will spread to all angles to emit light evenly and emit from the front of the light guide plate. Therefore, the excellent dot distribution of the light guide points on the light guide plate directly affects the light guide effect of the light guide plate. At present, the light guide plate...
