Problems solved by technology

However, because the light still needs to pass through the display panel to reach the camera, there will still be some problems in the photos or videos taken by the camera, such as diffraction after the light passes through the display panel, which will affect the display quality of the photos and videos taken. There is an urgent need for those skilled in the art to come up with a solution

Abstract

The invention provides a display panel and a display device. The display panel comprises a first display area, the first display area comprises a plurality of sub-pixel units, a protruding part is arranged in the first display area, the orthographic projection of the protruding part on the display panel is overlapped with the sub-pixel units, the protruding part is provided with a first side edge and a second side edge, a first driving electrode is arranged on the first side edge, and a second driving electrode is arranged on the second side edge; in the same sub-pixel unit, the first driving electrode and the second driving electrode are alternately arranged, and when different potential signals are applied to the first driving electrode and the second driving electrode, a horizontal electric field is formed between the first driving electrode and the second driving electrode; the liquid crystal molecules in the liquid crystal layer rotate in the horizontal electric field, the liquid crystal molecules do not generate obvious periodical inclination and torsion arrangement, the diffraction phenomenon generated by periodical arrangement of light through liquid crystal deflection is greatly weakened, and therefore the imaging effect 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] The rapid development of display technology has brought extraordinary experience to the display of information in people's life and work. People are pursuing higher and higher screen ratio of display panels. At present, display devices such as mobile phones and tablet computers often need to reserve space for commonly used front-facing cameras, infrared sensing devices, fingerprint recognition devices and other electronic photosensitive devices. Therefore, blind hole screens, notch screens, and water drop screens, which reserve space for cameras and sensing devices in the display area of ​​the display panel, emerged as the times require. [0003] However, people's pursuit of a true full screen has not stopped. More and more electronic photosensitive devices are integrated under the screen or inside the ...
