Abstract: A display device, a pixel compensation circuit and a driving method thereof are disclosed. The pixel compensation circuit includes: a driving transistor, an initialization circuit, a storage circuit, a first data writing circuit, a second data writing circuit, a compensation circuit and a light emitting control circuit. A first terminal of the storage circuit is coupled to the gate electrode of the drive transistor, and the first data writing circuit is configured to write a data signal to a second terminal of the storage circuit. The second data writing circuit is configured to change a potential of the second terminal of the storage circuit so that a potential of the first terminal of the storage circuit is associated with the data signal. The compensation circuit is configured to charge the first terminal of the storage circuit so that it is associated with a threshold voltage of the drive transistor.

Abstract: The present application discloses a display substrate including a base substrate; and a plurality of pixels on the base substrate. Each of the plurality of pixels in the display substrate includes a color generating layer on the base substrate; a first reflective layer surrounding at least one side of the color generating layer in plan view of the base substrate; and a second reflective layer having a light transmissive area and a light reflective area, the light transmissive area spaced apart from the first reflective layer in a direction perpendicular to the base substrate, the light reflective area configured to be spaced apart from the color generating layer in the direction perpendicular to the base substrate by an adjustable distance relative to the color generating layer. The first reflective layer is configured to reflect an incident light transmitted through the light transmissive area to the light reflective area, the light reflective area and the color generating layer are configured to direct the incident light reflected by the first reflective layer in a direction so that it may pass through the color generating layer.
