AI Technical Summary
Technical Problem
Existing OLED display products suffer from severe color shift when implementing privacy protection, which affects the display effect.
Method used
Design a display panel structure in which the light-emitting device layer includes privacy sub-pixels of different areas, and corresponding openings are set on the light-shielding layer so that the sub-pixels with smaller impact on brightness attenuation under wide viewing angles are larger, thereby reducing color shift.
Benefits of technology
By optimizing the sub-pixel area and the opening design of the light-shielding layer, the difference in brightness attenuation of the display panel under different viewing angles is reduced, color shift is reduced, and the display effect is improved.

Abstract
This application discloses a display panel and a display device. The display panel includes a substrate, a light-emitting device layer, and a light-shielding layer. The light-emitting device layer is disposed on one side of the substrate and includes a plurality of first pixels distributed in a privacy pixel area. The first pixels include first privacy sub-pixels and second privacy sub-pixels of different colors. The light-shielding layer is disposed on the side of the light-emitting device layer away from the substrate. The light-shielding layer has a first opening and a second opening respectively corresponding to the first privacy sub-pixels and the second privacy sub-pixels. The projected area of a single first privacy sub-pixel on the substrate is smaller than the projected area of a single second privacy sub-pixel on the substrate. The gap area between the orthographic projection of the first opening on the substrate and the orthographic projection of the first privacy sub-pixel on the substrate is S1, and the gap area between the orthographic projection of the second opening on the substrate and the orthographic projection of the second privacy sub-pixel on the substrate is S2. S1 and S2 satisfy: S1 > S2, thereby reducing the color shift phenomenon at the side viewing angle.
