Patent ID: 10242622

Abstract:
A pixel compensation circuit, an organic light-emitting display panel and an organic light-emitting display device are provided. The pixel compensation circuit includes a first switch transistor, a second switch transistor, a third switch transistor, a fourth switch transistor, a fifth switch transistor, a sixth switch transistor, a light-emitting element, a seventh switch transistor, a storage capacitor, and a drive transistor. The first switch transistor, the fourth switch transistor, and the fifth switch transistor provide a signal on a reference voltage signal terminal to a first node and provide a threshold voltage to a gate of the drive transistor. The second switch transistor and the third switch transistor couple a signal on a first power supply terminal in real time to the gate of the drive transistor. A driving current generated by the drive transistor is protected from adverse effects caused by IR Drop on the first power supply terminal.
