Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a display area, the display area comprises a first display area, a transition area and a second display area, and the sub-pixel density of the first display area, the sub-pixel density of the transition area and the sub-pixel density of the second display area are gradually increased. The first display area comprises a plurality of first sub-pixels, and the first pixel circuit for driving the first sub-pixels is located in the transition area, so that the light-transmitting area of the first display area is increased. The first sub-pixel is electrically connected with the first pixel circuit through a connecting line. The first line segment, the second line segment and the third line segment belong to different connecting lines, and the first line segment, the second line segment and the third line segment extend in the first direction and are sequentially arranged in the second direction. No gap exists between the first line segment and the second line segment and between the second line segment and the third line segment which are arranged in sequence, the light transmittance of the first display area can be improved, meanwhile, the diffraction phenomenon when light penetrates through the first display area is improved, and the optical performance of the under-screen optical device is improved.

Description

[0001] This application is a divisional application with an application date of December 2, 2019, an application number of 201911216232.X, and an invention-creation title of "a display panel and a display device". technical field [0002] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0003] 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 ratio has become the current research direction. For electronic products, the settings of optical devices such as front cameras will inevitably occupy a certain space, thus affecting the screen ratio. In order to increase the screen ratio and achieve a full screen, the researchers considered the implementation of the optical device under the screen. [0004] The optical device is...
