Description

technical field [0001] The invention discloses a laser precision micromachining device and method for a light guide plate, belonging to the field of high-end laser manufacturing equipment and advanced processing technology. Background technique [0002] Performance parameters such as brightness and uniformity of the backlight module directly affect the image quality of a liquid crystal display (LCD). Liquid crystal displays have more and more stringent requirements in terms of brightness and chromaticity, so the requirements for backlight modules are also getting higher and higher. The role of the light guide plate is to guide the scattering direction of light to improve the brightness and control the uniformity of the brightness. Therefore, the design and manufacture of the light guide plate is one of the key technologies of the backlight module. In the process of developing the light guide plate, the performance of the light guide plate is still determined by the distribu...
