  • 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.
