例如，散光膜60位于第二子背光源22邻近液晶显示屏10的表面，可以增加第二子背光源22的光线的均匀度。显示装置处于前显示模式时，第二子背光源22的光线通过散光膜60，为副显示区10B提供强度均匀的光线，以提高副显示区10B的显示画面的均匀度。For example, the diffuser film 60 is located on the surface of the second sub-backlight 22 adjacent to the liquid crystal display 10 , which can increase the light uniformity of the second sub-backlight 22 . When the display device is in the front display mode, light from the second sub-backlight 22 passes through the diffuser film 60 to provide light with uniform intensity to the sub-display area 10B, so as to improve the uniformity of the display image in the sub-display area 10B.
例如，散光膜60也可以位于第一子背光源21邻近液晶显示屏10的表面，以增加第一子背光源21的光线的均匀度。For example, the diffuser film 60 can also be located on the surface of the first sub-backlight 21 adjacent to the liquid crystal display 10 , so as to increase the light uniformity of the first sub-backlight 21 .
