Abstract

The present invention belongs to the technical field of light guide plate design, and aims to provide a light guide plate netted point design method through laser processing. Light guide plate netted points designed by the above method are linear. A density computational formula of the linear netted points is that D=L*S / PxPy, two-dimension coordinate planes using a geometric center of a light guide plate as an origin of the coordinates are established successively according to the above formula, a light emitting region is determined and divided into a plurality of regions which are endowed with different netted point density distribution, and a density distribution function of the light emitting region is obtained so as to determine the density distribution of the light emitting region, until the length L of the netted points is output. According to the whole process, a function language is converted through a VBA development tool into a computer language, thus to realize automatic arrangement of the linear netted points, the whole netted point distribution is not only high in automation degree, but also is short in required development time, few in development expense, simple in production technique, and high in yield. Light guide plates obtained according to a netted point distribution tendency obtained by the above method are excellent in uniformity and meet production requirements.

Description

technical field [0001] The invention belongs to the technical field of light guide plate design, and relates to a method for designing dots of a light guide plate, in particular to a method for designing dots of a laser-processed 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 / PC board. The light guide principle is mainly to use the optical grade acrylic board To absorb light so that the light stays on the surface of the plate, when the light hits the light guide point, through various light guide points of various densities and sizes, the reflected light will spread to all angles to emit light evenly and from the front of the light guide plate It can be clearly seen from this that the excellent distribution of the dots of the light guide points of the light guide plate will directl...
