Title
(EN) TOUCH DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE TACTILE
(ZH) 触控显示装置
Abstract
(EN)
A touch display device, comprising a protective layer, a display module, a touch layer, a fingerprint sensor layer, a back light source and a light-shielding layer, wherein the fingerprint sensor layer and the touch layer are stacked in a display area of the display device. By means of integrating the fingerprint sensor layer and the touch layer together, a fingerprint recognition function may be implemented at the same time that touch display is carried out, which not only reduces the number of production processes, but also lessens production costs and reduces the overall thickness of the display device.
(FR)
L’invention concerne un dispositif d'affichage tactile, comprenant une couche de protection, un module d'affichage, une couche tactile, une couche de capteur d'empreinte digitale, une source de lumière arrière et une couche de protection contre la lumière, la couche de capteur d'empreinte digitale et la couche tactile étant empilées dans une zone d'affichage du dispositif d'affichage. Au moyen de l'intégration de la couche de capteur d'empreinte digitale et de la couche tactile ensemble, une fonction de reconnaissance d'empreinte digitale peut être mise en œuvre en même temps que la réalisation d'un affichage tactile, ce qui permet non seulement de réduire le nombre de processus de production, mais également de réduire les coûts de production et de réduire l'épaisseur globale du dispositif d'affichage.
