Abstract
(EN)
A display panel (100) and a display device. The display panel (100) comprises a first driving circuit (131) and a plurality of first pixel units (120). The first pixel unit (120) comprises an image display area (121) and a light-transmitting area (122). The image display area (121) is driven by the first driving circuit (131) to provide a corresponding brightness, and is formed with a notch (124) at the edge thereof. The light-transmitting area (122) is formed in the notch (124) to allow incident light rays of the outer side directions of the display panel (100) to penetrate. The present invention improves the imaging quality of an under screen camera while guaranteeing pixel density.

La présente invention concerne un panneau d’affichage (100) et un dispositif d’affichage. Le panneau d’affichage (100) comprend un premier circuit de commande (131) et une pluralité de premières unités de pixel (120). La première unité de pixel (120) comprend une zone d’affichage d’image (121) et une zone de transmission de lumière (122). La zone d’affichage d’image (121) est commandée par le premier circuit de commande (131) pour fournir une luminosité correspondante et est formée avec une encoche (124) au niveau de son bord. La zone de transmission de lumière (122) est formée dans l’encoche (124) pour permettre la pénétration de rayons de lumière incidente selon les directions latérales externes du panneau d’affichage (100). La présente invention améliore la qualité des imageries d’une caméra sous écran tout en garantissant la densité des pixels.
