  • PIXEL COMPENSATION CIRCUIT, DRIVE METHOD THEREOF, AND DISPLAY PANEL
    Publication number: 20240304135
    Abstract: Disclosed are a pixel compensation circuit, a drive method thereof, and a display panel. The pixel compensation circuit includes a drive transistor, a data write module, a first initialization module, a second initialization module, a storage capacitor, and a light-emitting device. The drive timing of the pixel compensation circuit includes a threshold voltage compensation stage in which a detected threshold voltage of the drive transistor is less than an actual threshold voltage of the drive transistor.
