    • A backlight structure comprises a light-guide plate and a light source module. There is a light-entering surface, which is a burnished surface, on one side of the light-guide plate. Besides, there is an effective light-emitting area on the light source module, and there is a distance between the centerline of which area and that of the light-entering surface. Thereby, the luminance on the bottom-left corner of the backlight structure is made identical to the luminance on the bottom-right corner by increasing the propagation ranges of the light on the bottom-left and the bottom-right corners as a result of a burnish surface as well as of asymmetrically adapting the light source module.
    • 背光结构包括导光板和光源模块。 在导光板的一侧有一个光进入表面,它是抛光表面。 此外,在光源模块上存在有效的发光区域,并且在该区域与光入射表面的中心线之间存在距离。 由此,通过增加左下角和右下角的光的传播范围,使得背光结构的左下角的亮度与右下角的亮度相同,作为 抛光表面以及不对称地适应光源模块。
