摘要： The present invention is directed to a light guide plate, a backlight module and a display device with the light guide plate comprising a bottom surface containing space for holding light sources, a light emitting surface opposite the bottom surface and a quantum dot layer arranged in the containing space in the direction of the light emitting surface. Since the bottom surface of the light guide plate is provided with the containing space for holding the light sources, and the light sources are limited within the containing space, light diffusion due to the fact that the light sources are positioned outside the light guide plate is reduced, loss of light is reduced, and quantity of the light sources in the backlight module is reduced. Since the quantum dot layer is arranged in the containing space toward a direction of the light emitting surface, white mixed light is formed according to fluorescent effect of quantum dot materials. Further, as the quantum dots have the characteristics of high color gamut and high transmittance, display effect can be improved.
摘要翻译：本发明涉及一种导光板，背光模块和显示装置，其中导光板包括用于保持光源的底表面容纳空间，与底表面相对的发光表面和布置在其中的量子点层在发光面的方向上容纳空间。由于导光板的底面设置有用于保持光源的容纳空间，并且光源被限制在容纳空间内，所以由于光源位于导光板外侧的事实而引起的光扩散是降低了光的损失，降低了背光模块中的光源的数量。由于量子点层沿着发光面的方向配置在容纳空间中，所以根据量子点材料的荧光效果形成白色混合光。此外，由于量子点具有高色域和高透射率的特性，因此可以提高显示效果。

摘要： The present disclosure relates to a light guide plate and a fabricating method thereof, an array substrate and a fabricating method thereof, and a display device. In the light guide plate provided in the present disclosure, in a region corresponding to a first display region for arranging a gate driven circuit, more net-dots are provided or the diameter of net-dots is set to be larger, such that the luminance of outgoing light from the light guide plate in this region can be increased, thereby weakening the luminance difference between the corresponding display region and other display region.
