Description of the Invention (1) Technical Field The invention provides a method for defining a pattern on a light guide plate, especially a light guide plate pattern with simple process and high pattern completion rate Of processing methods. Prior technology Backlight modules are one of the important devices of liquid crystal display products, and they have been widely used in related products such as digital cameras, mobile phones, digital personal assistants (PDAs), computer monitors, and flat-screen TVs. Generally speaking, most backlight modules are arranged on the back of a display panel, and include a light source generator, a light guide plate, a reflection sheet, a diffusion sheet, and several types of optical films or prism sheets. . The light guide plate is used to diffuse the light source generated by the light source to the display panel, the diffuser plate is used to evenly disperse the light source, and the optical film or cymbal is placed above the diffuser plate to improve the brightness and uniformity of the backlight module. The backlight module can be roughly divided into two types: "direct-underlying" and "edge light". The design of the direct type backlight module is to place the light source generator on the back of the display panel. Due to the large installation space, multiple light tubes can be used to increase the intensity of the light source. Therefore, high-brightness, large-sized display panels are generally required, such as high-brightness or outdoor-used LCD monitors or LCD TVs, which are suitable for using direct-type backlight modules as display light sources.
