  • Patent number: 10482808
    Abstract: A pixel control circuit and a control method thereof, and a display device. The pixel control circuit includes a control-signal output sub-circuit and a switch sub-circuit. An input terminal of the switch sub-circuit is electrically coupled to an output terminal of the control-signal output sub-circuit. An input terminal of the control-signal output sub-circuit is electrically coupled to a data line. The control-signal output sub-circuit is configured to: compare a voltage received by the data line with a reference voltage; and if a value of the voltage is equal to a value of the reference voltage, output a first control signal, otherwise output a second control signal. The switch sub-circuit is configured to be turned off under control of the first control signal and turned on under control of the second control signal. The reference voltage is a corresponding gamma voltage when the display panel is in a dark state.

  • Patent number: 10209601
    Abstract: Disclosed are a display substrate and a driving method thereof, and a display device. The display substrate includes a plurality of pixels, a data signal chip and a control unit. Each of the pixels includes a white sub-pixel; the data signal chip is for transmitting a set of data signals to the pixels, the set of data signals including data signals transmitted to the white sub-pixel; and the control unit controls the white sub-pixel to be in a dark state when the data signal chip transmits a predetermined set of data signals to the pixels. When the data signal chip transmits the predetermined set of data signals to the pixels, the display substrate controls the white sub-pixel to be in a dark state.
