The invention belongs to the technical field of light guide plate design and aims to provide a method for designing dots of a laser-processed light guide plate. The dots of the light guide plate designed by the method are linear. In the present invention, the density calculation formula D=L*S / PxPy of linear dots is newly proposed, and a two-dimensional coordinate plane with the geometric center of the light guide plate as the origin of the coordinates is successively established around this formula to determine the light-emitting area, and assign Obtain the density distribution function of the luminous area for different dot density distributions to determine the density distribution of the luminous area until the length L of the output dots. The whole process uses the VBA development tool to convert the functional language into a computer language to realize the automatic arrangement of linear dots , the whole dot distribution not only has a high degree of automation, the required development time is relatively short, and the development cost is low, but also the production process is simple, and the yield rate of production is also high. In addition, the light guide plate obtained from the dot distribution trend obtained by this method The uniformity is good and meets the 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 on a light guide plate, in particular to a method for designing dots on a laser processing light guide plate. Background technique [0002] The light guide plate is a kind of light guide that uses high-tech materials with extremely high reflectivity and non-light absorption to print light guide points on the bottom surface of the optical grade acrylic / PC sheet. The light guide principle is mainly to use the optical grade acrylic sheet To absorb the light so that the light stays on the surface of the board. When the light hits the light guide point, it passes through a variety of dense and different light guide points. The reflected light will diffuse to all angles to emit light evenly and from the front of the light guide plate. From this, it can be clearly seen that the excellent dot distribution of the light guide points of the light guide ...
