Abstract
The disclosure relates to the field of liquid crystal display, specifically to a display screen frame eliminating apparatus and a display device. The display screen frame eliminating apparatus comprises a light source, a light tube and a drive module. The light tube comprises an upper surface and a lower surface, and the light source is located within the light tube or under the lower surface of the light tube. The light tube enables the light emitted by the light source to dispersedly exit from the upper surface. The drive module drives the light source to emit light based on the luminous condition of the edge pixels of the display area in the display screen. In this way, the light source emits light rays similar as the edge pixels of the display area in the display screen, and the light rays dispersedly exit from the upper surface of the light tube by means of the layered light tube structure. Therefore, to the human eyes, the display influence of the frame can be eliminated in all directions, and the display effect of the display device can be improved.
