Problems solved by technology

However, because the semi-transparent area needs to realize the display function, some metal traces will be set in the semi-transparent area, and because there are gaps between the metal traces, the existence of the gap is very prone to light diffraction, and the existence of the diffraction problem will affect the camera. The normal imaging function, resulting in unclear imaging, affecting the shooting effect

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display, the display panel comprises a display area and a non-display area, the display area comprises a conventional display area and a semi-transparent display area, and the pixel density of the conventional display area is greater than that of the semi-transparent display area; the semi-transparent display area comprises a shading part and a plurality of hollowed-out parts, and the hollowed-out parts penetrate through the shading part in the direction perpendicular to the light emitting surface of the display panel; wherein the contour line between the shading part and the at least one hollow part comprises at least two first arc lines and at least one second arc line, the second arc lineis connected with the two first arc lines, the curvature of the first arc line is S1, the curvature of the second arc line is S2, and S2 is larger than or equal to 3 * S1. Thus, when the contour linebetween the shading part and the hollow part comprises the arc lines with different curvatures, the diffraction degree of the semi-transparent area can be reduced, and the shooting image quality of the semi-transparent area is improved.

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 have higher and higher screen-to-body ratios, and full screens have attracted widespread attention due to their narrow-frame or even frame-less display effects. At present, display devices such as mobile phones and tablet computers often need to reserve space for electronic photosensitive devices such as commonly used front cameras, infrared sensing devices, and fingerprint recognition devices. For example, these photosensitive devices are arranged at the top of the front of the display device, and the corresponding position forms a non-display area, thereby reducing the screen-to-body ratio of the device. [0003] In the prior art, in order to increase the screen-to-body ratio, a high light transmission area may be provided in the disp...
