Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises light-emitting elements arranged in an array and a driving transistor electrically connected with the light-emitting elements; the display panel further comprises a substrate, a first electrode layer and a second electrode layer, the first electrode layer and thesecond electrode layer are insulated from each other, the first electrode layer and the second electrode layer are located on at least one side of the substrate in the direction perpendicular to thesubstrate, the first electrode layer comprises a first power line, and the second electrode layer comprises a second power line. A first pole of the light-emitting element is electrically connected with the first power line. A second pole of the light-emitting element is electrically connected with the first pole of the driving transistor for receiving a data signal; the second electrode of the driving transistor is electrically connected with the second power line; the control end of the driving transistor is electrically connected with the control signal line; the display panel further comprises a touch electrode, and the touch electrode multiplexes the first power line and / or the second power line. Therefore, the film layer structure of the display panel can be simplified, and the thickness of the display panel can be reduced.

Description

Technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] With the development of display technology, display panels integrated with touch functions have become a research hotspot and mainstream technology trend. In recent years, touch screen technology has gradually replaced button technology as the mainstream technology for mobile terminals and the like. Touch screen technology is a technology that determines the input information by detecting the touched position when a finger, pen, etc. touch the touch screen installed in the front of the display. At present, the application range of touch screens is very wide. The main products include touch-sensitive mobile phones, laptops and other mobile terminals, as well as man-machine display interfaces in the industrial automation industry. [0003] According to the composition structure, touch screens can be di...
