Problems solved by technology
During normal display, the semi-transparent area can play a display role; when a photo or video needs to be taken, the camera takes photos or videos through the semi-transparent area, so that the semi-transparent area can simultaneously realize the functions of display and shooting, but existing In the technology, when the light passes through the semi-transparent area, it is easy to diffract, and the imaging effect is poor, which leads to the starburst phenomenon when the camera takes pictures. The so-called starburst refers to the uniform radial diffraction fringes in the photo centered on the point light source.

The invention discloses a display panel and a display device, the display panel comprises a first display area and a second display area, and the light transmittance of the first display area is greater than that of the second display area; the display panel comprises a color film substrate, an array substrate and liquid crystal molecules, the color film substrate and the array substrate are oppositely arranged, the liquid crystal molecules are clamped between the color film substrate and the array substrate, and the color film substrate comprises a first substrate body and a black matrix located on the side, close to the array substrate, of the first substrate body. The orthographic projection of the black matrix on the plane where the first substrate is located is not overlapped with the orthographic projection of the first display area on the plane where the first substrate is located; in the first display area, a protruding column is further arranged between the color film substrate and the array substrate, the refractive index n1 of the protruding column is larger than the refractive index n2 of the liquid crystal molecules, or the refractive index n1 of the protruding column is smaller than the refractive index n2 of the liquid crystal molecules, and the difference between n1 and n2 is larger than 0.1. The diffraction phenomenon of the first display area is improved.
Description
technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the continuous improvement of people's requirements for visual experience of electronic products, full-screen technology has become one of the research hotspots in the field of display in recent years. [0003] In the prior art, in order to realize a full screen, a high light transmittance area can be set up in the display area of the display panel to accommodate the above-mentioned photosensitive device, for example, a semi-transparent area is set on the display screen, and the camera is set under the screen and corresponding in the semipermeable zone. During normal display, the semi-transparent area can play a display role; when a photo or video needs to be taken, the camera takes photos or videos through the semi-transparent area, so that the semi-transparent area can simultaneously r...
