Abstract

A display device, comprising a touch module having a first surface and a second surface; a cover plate disposed on the first surface of the touch module; a display module disposed on the touch module The second surface; the fingerprint identification element is located on the side of the display module away from the touch module; the decorative film is arranged between the display module and the fingerprint identification element. On the one hand, the decorative film can prevent the observer from seeing other structures behind the display module from the front of the display device when the display module is turned on; The penetration rate is quite high, so as to effectively sense the fingerprint generated by the touching finger at the position corresponding to the fingerprint identification element.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a display device. Background technique [0002] Fingerprint recognition technology has been widely used in various display devices, such as smart phones, tablet computers, and the like. In the existing display devices, since the fingerprint identification element is generally opaque, in order not to affect the display, the fingerprint identification element is usually arranged under the display module or in a non-display frame area. If it is arranged in the frame area, the size of the fingerprint identification element is also limited due to the limitation of the area of ​​the frame area, so that the fingerprint authentication area of ​​the display device is limited to the frame area. When the fingerprint identification element is arranged under the display module (such as the OLED display module), a black light-shielding layer needs to be provided between the display module and the...
