Problems solved by technology

[0004] However, due to the reduced sub-pixel density in the camera area, there is a significant load difference between the camera area and the non-camera area, resulting in an obvious split-screen phenomenon that affects the overall display effect

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area, the display area comprises a light sensation display area and a first display area which are arranged in the first direction, the display area comprises display sub-pixels, the light sensation display area further comprises virtual sub-pixels, and the total density of the display sub-pixels and the virtual sub-pixels in the light sensation display area is smaller than the density of the display sub-pixels in the first display area. The display panel further comprises a plurality of first signal lines which extend in the second direction and are arrayed in the first direction. The first signal lines comprise first sub-signal lines penetrating the light sensation display area and secondsub-signal lines penetrating the first display area, and the total number of the display sub-pixels and the virtual sub-pixels connected with the first sub-signal lines is equal to the number of the display sub-pixels connected with the second signal lines. The arrangement of the virtual sub-pixels can effectively compensate the load on the first sub-signal lines in the light sensation display area, so that the load difference of the first sub-signal lines and the second sub-signal lines due to the pixel density difference is reduced or even eliminated, the consistency of the load areas on thefirst sub-signal lines and the second sub-signal lines is ensured, and the display uniformity is effectively improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic light-emitting display devices have the advantages of self-illumination, low power consumption, and high brightness, and are widely used in various electronic display devices. [0003] At present, the full screen has begun to enter people's field of vision due to its stronger visual effects. However, due to the needs of display devices, especially mobile phones, which require front cameras and indicator lights, it cannot fully meet the technical requirements of the full screen. Therefore, in the prior art, the sub-pixel density of the front camera area is reduced, so that the front camera area increases the amount of light due to the reduction of the sub-pixel density, and the normal shooting function of the camera can be realized; while retaining a certain number of sub-pixels can also To meet ...
