Abrégé
Provided are a pixel compensation circuit and method and a display apparatus, which belong to the technical field of display. In the pixel compensation circuit, a sensing circuit can sense and output an electrical signal reflecting the temperature of a light-emitting device; when determining on the basis of the electrical signal that the temperature is abnormal, a sampling circuit can sample and output a real-time driving signal which is output by a pixel circuit to the light-emitting device; and, on the basis of the real-time driving signal, a compensation circuit can compensate a data signal. Therefore, the purpose of compensating a light-emitting driving signal output by the pixel circuit to the light-emitting device on the basis of the data signal can be achieved, and the effect of the abnormal temperature on the light-emitting driving signal can be avoided, thereby ensuring normal light emission of the light-emitting device, and achieving a good display effect of a display panel.

Abrégé
Provided is a display panel, used for mitigating the problem of generative black spots caused by moisture intrusion into a display area. The display panel comprises: a substrate, a plurality of sub-pixels, power lines, and an organic insulating layer. The substrate comprises a display area and a first bezel area located on one side of the display area in a first direction. The first bezel area comprises a bending area and a first wiring area located on the side of the bending area close to the display area. The plurality of sub-pixels are located in the display area. At least some of the power lines are located in the first wiring area and are electrically connected to the plurality of sub-pixels. The organic insulating layer may be located on the side of the power lines away from the substrate. An organic slot extending in a second direction is formed in the first wiring area. The organic slot passes through the organic insulating layer. Each power line is provided with at least one sidewall extending in the first direction, and the length of the edge of an overlapping area between the orthographic projection of the at least one sidewall on the substrate and the orthographic projection of the organic slot on the substrate is greater than the minimum length of the organic slot in the first direction.
The present application discloses a display panel and a display device. The display panel comprises: a substrate, a first electrode layer, a pixel definition layer, a light emitting layer, a second electrode layer, a touch electrode layer, and a light shielding layer. The light shielding layer is located on the side of the pixel definition layer facing the substrate. Thus, among light rays emitted from the light emitting layer, a portion of light rays emitted in a direction moving away from a light exit side can be blocked by the light shielding layer, thereby reducing the amount of light leakage of the display panel. In addition, the orthographic projection of the light shielding layer on the substrate overlaps the orthographic projection of the touch electrode layer on the substrate, that is, the structure of the light shielding layer is similar to that of the touch electrode layer. In this way, the amount of ambient light blocked can be reduced, thereby reducing a leaking light ratio, and further improving the brightness adjustment effect of a display device using the display panel.
