Abstract
(EN)
The present disclosure provides a display panel, comprising at least one pixel region in a display area. Each pixel region comprises: at least one first pixel, each first pixel comprising at least one display light-emitting sub-pixel and at least one near-infrared light-emitting sub-pixel, wherein the near-infrared light-emitting sub-pixel is configured to emit near-infrared light; and at least one second pixel, each second pixel comprising at least one display light-emitting sub-pixel and at least one near-infrared receiving sub-pixel, wherein the near-infrared receiving sub-pixel is configured to receive near-infrared light reflected from an external object and generate a measurement signal accordingly. The present disclosure also provides a display device comprising the display panel, and a method for determining the position of an external object using the display device.

La présente invention concerne un écran d'affichage, comprenant au moins une région de pixel dans une zone d'affichage. Chaque région de pixel comprend : au moins un premier pixel, chaque premier pixel comprenant au moins un sous-pixel électroluminescent d'affichage et au moins un sous-pixel électroluminescent proche infrarouge, le sous-pixel électroluminescent proche infrarouge étant configuré pour émettre une lumière proche infrarouge ; et au moins un second pixel, chaque second pixel comprenant au moins un sous-pixel électroluminescent d'affichage et au moins un sous-pixel de réception proche infrarouge, le sous-pixel de réception proche infrarouge étant configuré pour recevoir une lumière proche infrarouge réfléchie par un objet externe et pour générer un signal de mesure en conséquence. La présente invention concerne également un dispositif d'affichage comprenant l'écran d'affichage et un procédé de détermination de la position d'un objet externe à l'aide du dispositif d'affichage.
