  • Pixel circuit and display device
    Patent number: 11114035
    Abstract: A pixel circuit and a display device. The pixel circuit includes a charging unit, a light-emitting unit and an error compensation unit; a voltage storage terminal of the charging unit is connected to a voltage input terminal of the light-emitting unit; one end of the error compensation unit is connected to the voltage storage terminal of the charging unit, a voltage at the voltage storage terminal of the charging unit is used to determine a magnitude of a current flowing through the light-emitting unit; a control terminal of the error compensation unit is configured to receive a light-emitting control signal which is used to control the light-emitting unit to emit light or stop emitting light, the error compensation unit is configured to lower the voltage at the voltage storage terminal of the charging unit when the light-emitting control signal controls the light-emitting unit to emit light.
