Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a display area, wherein the display area comprises a first display area, a transition area and a second display area, wherein the sub-pixel density of the first display area, the transition area and the second display area is gradually increased. The first display area comprises a plurality of first sub-pixels, and a first pixel circuit for driving the first sub-pixels is located in the transition area, so that the light transmission area of the first display area is increased. The firstsub-pixels are electrically connected with the first pixel circuit through a connecting line. Each of a first line segment, a second line segment and a third line segment belongs to a different connecting line, and the first line segment, the second line segment and the third line segment all extend in a first direction and are sequentially arranged in a second direction. There is no gap between the first line segment and the second line segment arranged in sequence, and there is no gap between the second line segment and the third line segment arranged in sequence, so that the light transmittance of the first display area can be improved, the diffraction phenomenon when the light ray penetrates through the first display area is improved, and the optical performance of an under-screen optical device 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, 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 required, the po...
