Abstract
(EN)
Provided is a display device comprising a light detection function. Also provided is a display device comprising a function of biometric authentication such as is typified by fingerprint authentication. Also provided is a display device comprising both a function as a touch panel and the function of biometric authentication. This display device comprises a first substrate, a light-guiding plate, a first light-emitting element, a second light-emitting element, and a photoreceptor element. The first substrate is disposed opposite the light-guiding plate. The first light-emitting element and the photoreceptor element are disposed between the first substrate and the light-guiding plate. The first light-emitting element comprises a function of emitting first light via the light-guiding plate. The second light-emitting element comprises a function of emitting second light to a lateral surface of the light-guiding plate. The photoreceptor element comprises a function of receiving the second light and converting the second light to an electrical signal. The first light includes visible light and the second light includes infrared light.

La présente invention concerne un dispositif d’affichage ayant une fonction de détection de lumière. L'invention concerne également un dispositif d'affichage ayant une fonction d'authentification biométrique telle qu'elle est caractérisée par une authentification d'empreinte digitale. L'invention concerne en outre un dispositif d'affichage ayant une fonction en tant que panneau tactile et la fonction d'authentification biométrique. Ce dispositif d'affichage comprend un premier substrat, une plaque de guidage de lumière, un premier élément électroluminescent, un second élément électroluminescent et un élément photorécepteur. Le premier substrat est disposé à l'opposé de la plaque de guidage de lumière. Le premier élément électroluminescent et l'élément photorécepteur sont disposés entre le premier substrat et la plaque de guidage de lumière. Le premier élément électroluminescent a une fonction d'émission d'une première lumière par l'intermédiaire de la plaque de guidage de lumière. Le second élément électroluminescent a une fonction d'émission d'une seconde lumière vers une surface latérale de la plaque de guidage de lumière. L'élément photorécepteur a une fonction de réception puis de conversion de la seconde lumière en un signal électrique. La première lumière comprend une lumière visible et la seconde lumière comprend une lumière infrarouge.
