Abstract
(EN)
Disclosed are a display panel and a display device. The display panel comprises a touch sensing module (100). The touch sensing module (100) comprises: a touch unit (A1), a fingerprint sensing unit (A2), a vibration sounding unit (A3), and a common electrode (140). The common electrode (140) covers the touch unit (A1), the fingerprint sensing unit (A2), and the vibration sounding unit (A3), so as to transmit a touch signal, a fingerprint sensing signal, and a vibration sounding signal in a time-sharing manner, thereby realizing the functions of screen sound production and fingerprint recognition; moreover, punching in a front face of the display panel is not needed, thereby increasing the screen-to-body ratio.

L'invention concerne un écran d'affichage et un dispositif d'affichage. L'écran d'affichage comprend un module de détection tactile (100). Le module de détection tactile (100) comprend : une unité tactile (A1), une unité de détection d'empreinte digitale (A2), une unité de sondage de vibration (A3) et une électrode commune (140). L'électrode commune (140) recouvre l'unité tactile (A1), l'unité de détection d'empreinte digitale (A2), et l'unité de sondage de vibration (A3), de façon à transmettre un signal tactile, un signal de détection d'empreinte digitale et un signal de sondage de vibration d'une manière à partage de temps, ce qui permet de réaliser les fonctions de production de son d'écran et de reconnaissance d'empreinte digitale ; de plus, le poinçonnage dans une face avant de l'écran d'affichage n'est pas nécessaire, ce qui permet d'augmenter le rapport écran-corps.
