Description of the new type: [Technical field to which the new type belongs] This creation relates to a light guide plate and a backlight module using the light guide plate. [Previous Technology] Liquid crystal displays are widely used in modern information equipment due to their advantages such as lightness, thinness, shortness, and low power consumption. Liquid crystal display panels are important components of liquid crystal displays. Since the liquid crystal in the liquid crystal display panel itself does not have light-emitting characteristics, in order to achieve the display effect, it is necessary to provide the liquid crystal display panel with a side light source device, such as a backlight module, whose function is to supply the liquid crystal display panel with a surface with sufficient brightness and uniform distribution. light source. In response to the current requirements for lightness, thinness and shortness of electronic products', its liquid crystal display module needs to effectively use space. The light guide plate and the light source collide with each other due to force or vibration. "The white light stomach light plate group is mainly composed of a light source and a light guide plate. Among them, the light source can be set on the light guide of the light guide plate. The side of the light guide plate is to guide the transmission Direction, so that the light is uniformly emitted from the light guide and the light exit surface. Because the light emitted from the light source enters the light entrance surface of the light guide plate, the relative position of the light entrance surface of the light plate and the light source can control the luminous brightness. Therefore, in order to improve the light guide plate, The luminous brightness of the light guide plate should be close to the silk light guide plate. However, because the structure of the light source itself is more blue and the light guide is not the same as the light-emitting device, it is different from the backlight module of a conventional technology.
