Abstract
An optical film layer, a backlight module, and a display device are proposed. A black shading district is disposed on a terminal of the optical film layer for preventing light produced by a light source from entering the optical film layer through the terminal of the optical film layer. In this way, light leakage will not happen since the light which partially enters the optical film layer is blocked off. Display quality of the display device, especially display quality of the display device having a narrow bezel is improved.
Claims14
An optical film layer, comprising a terminal on which a black shading district is disposed, for preventing light produced by a light source from entering the optical film layer through the terminal.
A backlight module, comprising:
- a light guide plate (LGP) comprising an incident surface and an emitting surface;
- a light source, disposed opposite to the incident surface;
- and
- an optical film layer, disposed on the emitting surface, wherein a black shading district is disposed on a terminal of the optical film layer which is near the light source, for preventing light produced by the light source from entering the optical film layer through the terminal.
A display device, comprising a display panel and a backlight module, wherein the backlight module comprises:
- a light guide plate (LGP), comprising an incident surface and an emitting surface;
- a light source, disposed opposite to the incident surface;
- an optical film layer, disposed on the emitting surface, wherein a black shading district is disposed on a terminal of the optical film layer which is near the light source, for preventing light produced by the light source from entering the optical film layer through the terminal;
- the display panel disposed on top of the optical film layer, the display panel comprising a display district, and the black shading district disposed outside of the display district.
