Display panel and display device

Abstract

The invention provides a display panel and a display device. A display area of the display panel comprises an optical component area, a transition area and a first display area. The display area comprises a light-emitting device and a pixel circuit, and the light-emitting device comprises a first light-emitting device located in the optical component area. The pixel circuit comprises a first pixel circuit located in the transition area. The first light-emitting device is electrically connected with the first pixel circuit through a connecting line. The pixel circuit comprises a first transistor and a second transistor, an active layer of the first transistor is located on a first silicon semiconductor layer, and an active layer of the second transistor is located on a second metal oxide semiconductor layer. The connecting line comprises a first line segment and a second line segment which are mutually connected, the first line segment is located in the optical component area, and the second line segment is located in the transition area. The connecting line comprises a first connecting line, and the first line segment in the first connecting line is located on the second metal oxide semiconductor layer. The light transmittance of the optical component area can be improved, meanwhile, the technological process can be saved, and the manufacturing cost can be reduced.

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] In electronic products such as mobile phones and tablet computers, optical components such as front cameras and infrared sensing elements occupy a certain amount of space on the front of the product and affect the screen-to-body ratio. With the introduction of the full screen concept in the display field, major manufacturers are making efforts in the field of full screen research. At present, it is generally believed that the under-screen optical component solution is a better solution that can realize a true full screen. The optical components such as the camera are arranged under the display area, and the position of the camera can be displayed normally. When the camera needs to be used, the light penetrates the display panel to reach the camera and is finally used by the camera. [0003] The electron...
