  • Publication number: 20260188228
    Abstract: A pixel drive circuit, which includes an adjustment sub-circuit, a drive sub-circuit, a compensation sub-circuit, a drive control sub-circuit, a first reset sub-circuit, a second reset sub-circuit, a first light-emitting control sub-circuit, a second light-emitting control sub-circuit and a storage sub-circuit. In the present application, the pixel drive circuit compensates for the leakage current at a first node during a data writing phase, enabling the drive transistor to continuously generate a drive current during a light-emitting phase. As a result, the display device employing the pixel drive circuit exhibit superior brightness performance, excellent light-emitting effects, and enhanced overall performance.

  • Publication number: 20260065873
    Abstract: A display panel and a driving method thereof, and a display apparatus are provided. The display panel includes multiple pixel units. Each data line is electrically connected to a column of the multiple pixel units. A source driving module is electrically connected to multiple data lines and outputs data signals to the multiple data lines. Each scan line is electrically connected to a row of the multiple pixel units for inputting scan signals to the multiple pixel units. A gate driving module includes multiple gate driving units and multiple voltage division units. One gate driving unit is electrically connected to one voltage division unit and one scan line. The gate driving unit outputs a driving signal to the voltage division unit to form the scan signal. In a direction away from the source driving module, voltages of the scan signals in the multiple scan lines are sequentially increased.

  • Patent number: 12387693
    Abstract: Disclosed are a gate row driving circuit and a driving method thereof, and a display substrate. The gate row driving circuit includes: an input module; a driving module, configured to connect to a pixel driving voltage output by the input module and provide a pixel power supply voltage to power a current pixel row under drive of the pixel driving voltage; a thermoelectric module, configured to perform thermoelectric conversion on operating heat when the operating heat of the driving module matches preset charging heat to obtain compensation power; and a capacitor module. The driving module is also configured to superimpose a charging voltage continuously generated by the capacitor module onto the pixel driving voltage after the thermoelectric module charges the capacitor module according to the compensation power to obtain an updated pixel driving voltage.
