Abstract

The invention discloses a display panel and a display device. The display panel comprises a first display region, a second display region and a non-display region; first light-emitting elements and second light-emitting elements, wherein the first light-emitting elements are arranged in the first display region, and the second light-emitting elements are arranged in the second display region; a first pixel circuit and a second pixel circuit, wherein the first pixel circuit is correspondingly and electrically connected with the at least one first light-emitting element, the second pixel circuit is correspondingly and electrically connected with the at least one second light-emitting element, and the second pixel circuit is located in the second display region; and a power line which comprises a first power supply structure and a second power supply structure which are electrically connected with each other, the first power supply structure is electrically connected with the first pixel circuit, the second power supply structure is electrically connected with the second pixel circuit, and at least one side of the first power supply structure is disconnected with the second power supply structure. According to the display panel, the occupied region of the power line at the local position of the display panel is reduced, and arrangement of other circuit structures is facilitated.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] In electronic devices including display panels, the pursuit of a high screen-to-body ratio with better visual experience has become one of the trends in the development of current display technologies. [0003] Taking mobile phones, tablet computers, etc. as examples, in the current full-screen solution, the display panel includes a first display area and a second display area, wherein the first display area is multiplexed as a photosensitive element integration area. At this time, photosensitive elements such as front cameras and infrared sensing elements can be arranged on the back of the first display area of ​​the display panel, and light can pass through the first display area to reach the photosensitive elements to realize corresponding functions such as front camera and infrared sensing. . [0004] In the abo...
