Abstract

The invention discloses a display panel and a display device. The display panel has a first display area and a second display area. The first display area is distributed with a plurality of first pixel units, and the second display area is distributed with a plurality of second pixels. units, the distribution density of the first pixel units in the first display area is smaller than the distribution density of the second pixel units in the second display area; the first display area includes a light-transmitting area and a pixel area, the first pixel units are distributed in the pixel area, and the transmission The light area includes a plurality of sub-light-transmitting areas, the pixel area includes a plurality of sub-pixel areas, and the sub-pixel areas and the sub-light-transmitting areas are alternately distributed in a first direction, and the first direction is a direction from the center of the central area to the second display area; The edge contours of the orthographic projections of the region and the sub-pixel region on the display surface of the display panel are polygonal, and if the number of sides of the polygon is greater than N, N>4. Reduce the impact of diffraction and interference effects on light uniformity, improve image quality to ensure imaging clarity while reducing diffraction in the first display area.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel and a display device. Background technique [0002] With the development of display technology, people not only require a smooth user experience for the electronic products they use, but also have higher and higher requirements for visual experience. High screen-to-body ratio has become the current research direction. For electronic products, the setting of optical devices such as front cameras will inevitably occupy a certain amount of space, thereby affecting the screen-to-body ratio. In order to increase the screen-to-body ratio and realize a full screen, researchers consider the implementation of optical devices under the screen. [0003] The optical device is arranged under the film layer where the light-emitting device of the display panel is located, that is, the optical device is arranged in the display area. When the display is r...
