Abstract
The present invention provides a display device. The device is provided with an opening on a film structure on a back surface of a display panel, and a fingerprint recognition module is arranged in the opening, thereby reducing distance between the fingerprint recognition module and the back surface of the display panel, to improve fingerprint recognition accuracy. In addition, the fingerprint recognition module can also be located at any position in middle range of the display panel, and is not limited to the edge region at the bottom of the display panel, so as to improve a screen ratio of the display device.
Claims14
A display device, comprising:
- a display panel having a display surface and a back surface disposed opposite to each other, wherein the display surface has a display area for displaying images;
- a thin film structure disposed on the back surface of the display panel, wherein the thin film structure is provided with an opening;
