Problems solved by technology

However, when the fingerprint recognition is set in the non-display area, it is not conducive to the narrow frame design of the display device. When it is set on the back, the thickness of the display device increases, which is not conducive to the thinner design; and the opening on the cover or back shell may reduce the display device. Due to the rigidity of the structure, dust, water stains, etc. can easily enter the display device through the opening, which will affect the performance of the electronic devices inside the display device.

Abstract

The application discloses a touch control display panel. The touch control display panel comprises a display area, and further comprises a colored film substrate, a cover plate and a fingerprint detection electrode, wherein the fingerprint detection electrode is arranged in the display area, the fingerprint detection electrode is located between the colored film substrate and the cover plate, and the fingerprint detection electrode is used for receiving fingerprint detection signals, and generates fingerprint sensing signals according to sensed fingerprints. The touch control display panel can achieve lighting and thinning and narrow bezel design of a display device having a fingerprint detection function.

Description

Technical field [0001] This application relates to the field of display technology, in particular to a touch display panel. Background technique [0002] With the development of display technology, the security of personal information by electronic display devices has become an increasingly important performance indicator. Fingerprint recognition is a highly reliable method of identity authentication. Through fingerprint recognition, the information security of users of electronic equipment can be effectively guaranteed. [0003] Currently, electronic display devices can be equipped with fingerprint recognition sensors. Generally, the fingerprint recognition sensor is large in size and occupies a large area. In most of the existing electronic display devices with fingerprint recognition function, the fingerprint sensor is usually set in the non-display area, or placed on the back of the display device. The cover or the back shell uses an opening process to make an opening, and th...
