Problems solved by technology

[0003] For Organic Light-Emitting Diode (OLED), due to its self-luminous characteristics and high transmittance of the light-emitting layer, it meets the conditions of fingerprint recognition and is easy to realize fingerprint recognition under the screen, but for Liquid Crystal Display (Liquid Crystal Display) , LCD), because it requires a backlight, on the one hand, the brightness of the backlight is lower than that of the active light-emitting type of the OLED, and it needs to pass through the upper and lower polarizers and the liquid crystal panel, and its transmittance is very low, which is difficult to meet the optical requirements Fingerprint Recognition Requirements

Abstract

The embodiment of the invention provides a display panel. The display panel comprises a display screen, a first backlight module, a second backlight module and a fingerprint sensor. The second backlight module has a fingerprint identification mode and a display mode, in the fingerprint identification mode, light penetrates through the second backlight module to reach the fingerprint sensor to perform fingerprint identification, and in the display mode, the second backlight module and the first backlight module provide uniform backlight for the display screen. By arranging the second backlightmodule, the display panel can achieve the function of being compatible with under-screen fingerprint recognition and display.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Fingerprint recognition is widely used in portable electronic products, not only for screen unlocking, but also for mobile payment, etc., which increases the security of use. The area of ​​traditional fingerprint recognition is outside the screen. With the development trend of high screen-to-body ratio, for 100% full screen, there is no area on the front of the mobile phone to place the fingerprint sensor. Therefore, fingerprint recognition under the screen is the development trend of mobile phone fingerprint recognition. [0003] For Organic Light-Emitting Diode (OLED), due to its self-luminous characteristics and high transmittance of the light-emitting layer, it meets the conditions for fingerprint recognition and is easy to realize fingerprint recognition under the screen, but for Liquid Crystal Di...
