  • Pixel circuit, control method for the same and display device
    Patent number: 11335262
    Abstract: The present disclosure provides a pixel circuit, a control method for the same, and a display device. The pixel circuit comprises a pixel driving circuit, a mode selecting circuit, and a light emitting device. The pixel driving circuit is configured to output a driving current. The mode selecting circuit is configured to select a different light emitting mode according to a different mode selecting signal. The light emitting device is configured to emit light having a different brightness according to a different light emitting mode. The light emitting device comprises a first electrode structure, a second electrode structure, and a functional layer between the first electrode structure and the second electrode structure. The mode selecting circuit comprises a first switching sub-circuit and a second switching sub-circuit.
