Abstract
A display panel includes a transparent substrate, a visible light backlight source, an infrared backlight source, a plurality of gate lines, a plurality of display data lines, a plurality of sensing data lines, a plurality of display transistors, a plurality of display pixels, a plurality of sensing pixels, and plurality of sensing transistors. When the display transistors receive the scanning signals, the display pixels are configured to display grayscale according to the visible light and the display data signals. When the sensing transistors receive the scanning signals, the sensing pixels are configured to generate detecting signals after conducting the sensing signals to the plurality of sensing data lines. Fingerprint recognition can be implemented on the display area of display panel without extra fingerprint recognizing components so that the screen can be minimized and the smart terminals can be lighter.
