Problems solved by technology

When the pixel density of the area where the photosensitive element is located decreases, the brightness of the area will decrease.
Therefore, when displaying, there will be bright lines at the junction of the area where the photosensitive element is located and the normal display area, resulting in split screens and affecting the display effect

Abstract

An embodiment of the invention discloses a display panel and a display device. The display panel comprises a first display area and a second display area, the second display area comprises a first sub-display area and a second sub-display area, and the light transmittance of the second sub-display area is larger than that of the first display area. A first pixel circuit is located in the first display area, and a second pixel circuit is located in the first sub-display area. A first light-emitting repeating unit is located in the first display area and comprises at least one first light-emitting unit, a second light-emitting repeating unit is located in the second display area and comprises at least two second light-emitting units, in the same first light-emitting repeating unit, all the first sub-light-emitting elements of at least one same color are electrically connected with the same first pixel circuit, and in the same second light-emitting repeating unit, all the second sub-light-emitting elements with at least one same color are electrically connected with the same second pixel circuit. Therefore, the light transmittance of the second display area is improved, and a split screen phenomenon is 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] With the development of display technology, display panels with a higher screen-to-body ratio have received more attention. In order to increase the screen-to-body ratio, a high-transmittance area can be provided in the display area of ​​the display panel to accommodate photosensitive elements, such as front-facing cameras, infrared sensing devices, fingerprint recognition devices, and the like. [0003] Due to the limited light transmission area in the display area, in order to increase the light transmittance and improve the optical performance of the photosensitive element under the screen, the conventional setting method is to reduce the pixel density in the area where the optical device is located. When the pixel density in the area where the photosensitive element is located decreases, the brightn...
