Problems solved by technology

[0002] In the existing technology, for full-screen display products with face recognition function, it is necessary to try to place the face recognition device under the display screen to perform face recognition under the screen. Therefore, the area for face recognition under the screen needs to meet the requirements of the display screen. High transmittance, so the display screen needs to be equipped with blind hole areas, and the blind hole areas do not have sub-pixels, so they cannot be displayed
[0003] To sum up, the existing full-screen display products with face recognition function, when the full-screen display, because the blind hole area does not emit light, there will be dark spots on the screen, and the full-screen display has display defects, which affects the overall display effect

Embodiment Construction

[0040] The embodiment of the present application provides a display panel, such as figure 1 As shown, the display area of ​​the display panel includes: a blind hole area 1 and an optical compensation area 2 surrounding the blind hole area 1; the optical compensation area 2 includes: an optical compensation sub-pixel 3 surrounding the blind hole area , and the reflective structure 4 located on the side of the optical compensation sub-pixel 3 close to the blind hole area 1; in the direction perpendicular to the plane where the display panel is located, the orthographic projection of part of the reflective structure 4 is in line with the optical The orthographic projections of the compensated sub-pixels 3 overlap.

[0041] In the display panel provided by the embodiment of the present application, since the optical compensation area is set around the blind hole area, the light emitted by the optical compensation sub-pixels in the optical compensation area can enter the blind hole...

Abstract

The invention discloses a display panel, a preparation method thereof and a display device, which are used for relieving display defects caused by non-luminescence of a blind hole area and improving adisplay effect. According to the invention, the display area of the display panel comprises a blind hole area and an optical compensation area surrounding the blind hole area. The optical compensation area comprises an optical compensation sub-pixel surrounding the blind hole area and a reflection structure located on the side, close to the blind hole area, of the optical compensation sub-pixel;in the direction perpendicular to the plane where the display panel is located, the orthographic projections of part of the reflection structures are overlapped with the orthographic projections of the optical compensation sub-pixels.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the existing technology, for full-screen display products with face recognition function, it is necessary to try to place the face recognition device under the display screen to perform face recognition under the screen. Therefore, the area of ​​face recognition under the screen needs to meet the requirements of the display screen. High transmittance, so the display screen needs to be equipped with blind hole areas, and the blind hole areas do not have sub-pixels, so they cannot be displayed. [0003] To sum up, the existing full-screen display products with face recognition function, when the full-screen display, because the blind hole area does not emit light, there will be dark spots on the screen, and the full-screen display has display defects, which affects the...
