Abstract
(EN)
A display panel (1) and a display device, the display panel (1) comprising: a drive circuit layer (120) and a light-emitting functional layer (130). A through hole is provided in a region of the drive circuit layer (120) corresponding to an under-display electronic element (2), and pixel drive circuits (121,122) corresponding to the region of the under-display electronic element (2) are provided in other display areas or non-display areas (200), thereby solving the technical problem that light transmission and display cannot be both achieved at the region of an under-display camera of an existing display panel.
(FR)
La présente invention concerne un panneau d'affichage (1) et un dispositif d'affichage, le panneau d'affichage (1) comprenant : une couche de circuit d'attaque (120) et une couche fonctionnelle électroluminescente (130). Un trou traversant est ménagé dans une région de la couche de circuit d'attaque (120) correspondant à un élément électronique sous-affichage (2), et des circuits d'attaque de pixels (121, 122) correspondant à la région de l'élément électronique sous-affichage (2) sont fournis dans d'autres zones d'affichage ou de non-affichage (200), ce qui permet de résoudre le problème technique selon lequel la transmission et l'affichage de lumière ne peuvent pas tous deux être réalisés au niveau de la région d'une caméra sous-affichage d'un panneau d'affichage existant.
