Title
(EN) DISPLAY PANEL AND DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE ET DISPOSITIF D'AFFICHAGE
(ZH) 一种显示面板及显示装置
Abstract
(EN) Embodiments of the present application provide a display panel and a display device. 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 recognition mode and a display mode. In the fingerprint recognition mode, light passes through the second backlight module to reach the fingerprint sensor for fingerprint recognition, and in the display mode, the second backlight module and the first backlight module provide uniform backlight to the display screen. Therefore, the display panel integrates under-screen fingerprint recognition and display functions.
(FR) Des modes de réalisation de la présente invention concernent un panneau d'affichage et un dispositif d'affichage. Le panneau d'affichage comprend : un écran d'affichage, un premier module de rétroéclairage, un second module de rétroéclairage et un capteur d'empreintes digitales. Le second module de rétroéclairage présente un mode de reconnaissance d'empreintes digitales et un mode d'affichage. Dans le mode de reconnaissance d'empreintes digitales, la lumière traverse le second module de rétroéclairage pour atteindre le capteur d'empreintes digitales pour la reconnaissance d'empreintes digitales, et dans le mode d'affichage, le second module de rétroéclairage et le premier module de rétroéclairage fournissent un rétroéclairage uniforme à l'écran d'affichage. Par conséquent, le panneau d'affichage intègre des fonctions de reconnaissance et d'affichage d'empreintes digitales sous-écran.
(ZH) 本申请实施例提供一种显示面板,该显示面板包括:显示屏、第一背光模组、第二背光模组以及指纹传感器。其中,第二背光模组具有指纹识别模式和显示模式,在指纹识别模式下,光线透过第二背光模组到达指纹传感器并进行指纹识别,在显示模式下,第二背光模组与第一背光模组向显示屏提供均匀背光。从而使显示面板实现兼容屏下指纹识别与显示功能。
