Abstract: A pixel driving circuit is provided. The pixel driving circuit includes an initialization circuit, a driving circuit, and a first light-emitting control circuit. A first terminal of the driving circuit is coupled to a power voltage terminal, a second terminal of the driving circuit is coupled to a light-emitting element via the first light-emitting control circuit. The initialization circuit is configured to write an initialization voltage to a control terminal of the driving circuit under control of an initialization control signal input from an initialization control line, so that the driving circuit brings a connection between the first and second terminals into a conducting state under control of the control terminal. The first light-emitting control circuit is configured to bring a connection between the second terminal and the light-emitting element into a conducting state under control of a first light-emitting control signal input from a first light-emitting control line.

Abstract: The present disclosure provides a display panel including a plurality of pixels, each of which includes at least one sub-pixel. Each sub-pixel includes a color reflection box and a control unit configured to control a color to be displayed by the color reflection box. The control unit is configured to, in the presence of ambient light, control a position of a light-entering surface of a shielding member in the corresponding color reflection box relative to a light-entering surface of a case in accordance with a display image at a corresponding position, so as to enable the color reflection box to display a color of the light-entering surface of the shielding member or a color of a colored material.
