Abstract
The invention relates to a laser processing method and system for a polarizer. The laser processing method comprises the steps that target processing parameters of the to-be-processed polarizer fixedto a processing platform are obtained, and the target processing parameters comprise the target processing speed and the target light emitting frequency; the target processing speed is used for controlling the processing platform to work at the target processing speed; the current motion speed of the processing platform is detected; and the current light emitting frequency is adjusted according tothe current motion speed and the target light emitting frequency of the processing platform. Through the laser processing method of the polarizer, segmented control can be conducted on a processing graph of the to-be-processed polarizer, different processing parameters are adopted correspondingly at different segments, however, it is ensured that the ratio of the processing speed in each segmentto the light emitting frequency is constant, that is, the point spacing of laser focusing light spots is constant, so that the processing effect in each segment is consistent, thus it is ensured thatthe number of the processing times required in various directions is constant, the control process is simplified, and the production efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of laser processing, in particular to a laser processing method and a laser processing system for a polarizer. Background technique [0002] Polarizer (Polarizer) is called a polarizer, which can control the polarization direction of a specific beam. The main function is to convert non-polarized natural light into polarized light, through the steering of liquid crystal, to control the penetration of light, and then produce the display effect of light and dark on the panel, and use the torsion characteristics of liquid crystal molecules to achieve the control of light pass degree. [0003] For the processing methods of polarizers, most of them are currently realized by laser. However, in the current process of laser processing polarizers, due to the unique polarizing properties of polarizers, the number of cuts required for cutting different processing directions of polarizers is different, the pr...
