The present application relates to a laser processing method and a laser processing system for a polarizer. The method includes: acquiring target processing parameters of a polarizer to be processed fixed on a processing platform, where the target processing parameters include target processing speed and target light output frequency; The processing speed is used to control the processing platform to work at the target processing speed; detect the current movement speed of the processing platform; adjust the current light output frequency according to the current movement speed of the processing platform and the target light output frequency. Through the above laser processing method of polarizer, segmental control can be realized on the processing pattern of the polarizer to be processed. Different segments correspond to different processing parameters, but the ratio of processing speed to light output frequency in each segment is guaranteed to be constant. , that is, the point spacing of the laser focusing spot is constant, so that the processing effect in each section is consistent, thereby ensuring the same number of processing times required for each processing direction, simplifying the control process and improving production efficiency.
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...
