Abstract: The present invention provides a light guide plate and a backlight module. The light guide plate has a light incident surface that has an arc configuration. The light guide plate includes an upper surface and a lower surface that have sides that are adjacent to the light incident surface and are respectively provided with a first slope surface and the second slope surface, so that large angle light, after being subject to an effect of convergence with the arc light incident surface, is subjected to total internal reflection at the first slope surface and the second slope surface to have the light guided into the light guide plate. The light guided into the light guide plate, after transmission and reflection, projects out through a light exit surface thereby improving light utilization and increasing light coupling efficiency. Since the light guide plate having the above-described structure demonstrates an excellent effect of convergence for light of all angles, the light guide portion of the light guide plate can be structured thinner without deteriorating light coupling efficiency, thereby facilitating a design of thinning of a backlight module. The present invention provides a backlight module, which involves a light guide plate having the above-described unique structure, so that the backlight module has a reduced thickness and a bettered effect of light emission.
Abstract translation: 本发明提供一种导光板和背光模块。 导光板具有弧形配置的光入射面。 导光板包括具有与光入射面相邻的侧面的上表面和下表面，并且分别设置有第一倾斜面和第二倾斜面，使得大角度光在受到影响之后 与电弧光入射表面的会聚，在第一倾斜面和第二倾斜面进行全内反射，使光线导向导光板。 在透射和反射之后导入导光板的光通过光出射表面突出，从而提高光利用率并提高光耦合效率。 由于具有上述结构的导光板表现出对所有角度的光的会聚的优异效果，所以导光板的导光部可以被构造得更薄，而不会降低光耦合效率，从而有利于设计薄型化 背光模组。 本发明提供一种背光模块，其包括具有上述独特结构的导光板，使得背光模块具有减小的厚度和更好的发光效果。

Abstract: Disclosed are a frame, a backlight module, and a liquid crystal display device. The frame has an accommodation space which is configured to accommodate a light guide plate, and one side of the frame is provided with a reflection positioning structure, which corresponds to a light incident side of the light guide plate. The reflection positioning structure has a plurality of LED placement grooves in which LEDs are placed, and an open end of each LED placement groove is located on one side of the frame parallel to the light guide plate. Each LED placement groove is provided with an LED light outlet hole on one side thereof near the light guide plate, and the reflection positioning structure is provided with a reflective layer on one side thereof near the light guide plate. The frame of the present disclosure can reflect light leaking from the light guide plate back to the light guide plate so as to increase the light utilization efficiency.
