Abstract
(EN)
A liquid crystal display panel (100) and a liquid crystal display device (1000). The liquid crystal display panel comprises an array substrate (11), a color film substrate (12), liquid crystals (13), and a fingerprint recognition module (14). The array substrate (11) is provided on the side facing a user. The liquid crystals (13) are provided between the array substrate (11) and the color film substrate (12). The fingerprint recognition module (14) is provided on the side of the array substrate (11) facing the liquid crystals (13). The fingerprint recognition module (14) comprises a thin film transistor (141) and a photodiode (142) for converting optical energy into electrical energy. The thin film transistor (141) is electrically connected to an output end of the photodiode (142).

L'invention concerne un panneau d’affichage à cristaux liquides (100) et à un dispositif d’affichage à cristaux liquides (1000). Le panneau d’affichage à cristaux liquides comprend un substrat de réseau (11), un substrat de film coloré (12), des cristaux liquides (13) et un module de reconnaissance d'empreinte digitale (14). Le substrat de réseau (11) est disposé sur le côté faisant face à un utilisateur. Les cristaux liquides (13) sont disposés entre le substrat de réseau (11) et le substrat de filtre coloré (12). Le module de reconnaissance d'empreinte digitale (14) est disposé sur le côté du substrat de réseau (11) faisant face aux cristaux liquides (13). Le module de reconnaissance d'empreintes digitales (14) comprend un transistor à films minces (141) et une photodiode (142) pour convertir l'énergie optique en énergie électrique. Le transistor à films minces (141) est connecté électriquement à une extrémité de sortie de la photodiode (142).
