Abstract

A display panel includes a transparent substrate, a visible backlight, an infrared backlight, a gate line, a display data line, a sensing data line, a display transistor, a display pixel electrode, adetection pixel electrode, and a sensing transistor. The display panel includes a transparent substrate, a visible backlight, an infrared backlight, a gate line, a display data line, a sensing data line, a display transistor, a display pixel electrode, a detection pixel electrode, and a sensing transistor. When the display transistor receives the scanning signal, the display pixel electrode is electrically connected with the display transistor, and the gray scale is displayed according to the visible light and the display data signal. When the sensing transistor receives the scanning signal, the sensing signal is turned on to the sensing data line to sense the intensity of the infrared light reflected by the transparent substrate to generate the sensing signal. By using the display panel provided by the invention, the fingerprint identification function of the display panel can be achieved without additional fingerprint identification elements, and the display panel is helpful to display the panel without a border.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device that can realize fingerprint recognition. Background technique [0002] With the rapid development of smart terminals and mobile payments, the usage rate of smart terminals is increasing. In order to prevent the payment software of smart terminals from being stolen by others, the user verification function of smart terminals is becoming more and more important. Common verification methods include password verification, face verification, and fingerprint verification. Fingerprint verification is widely used in user verification procedures of smart terminals due to the small sampling area, low fingerprint repetition rate, and simple identification technology. [0003] A common fingerprint sampling method is to install fingerprint recognition components on smart terminals. With the development of narrow-frame touch display panels, the fingerpri...
