摘要： 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.

摘要： An organic light emitting (OLED) display panel, a driving method thereof, and a display apparatus are provided. The OLED display panel comprises a display region including N number of pixel rows and a non-display region including a light-emitting driver circuit and a scanning driver circuit. The display region includes a first display region including N1 number of pixel rows and a second display region including N2 number of pixel rows, where N1, N2, and N are positive integers, and N1+N2=N. A pixel row in the second display region has a smaller number of pixels than a pixel row in the first display region. The light-emitting driver circuit is configured to, in scanning time S for each frame, supply a light-emitting control signal having n number of light-emitting cycles to each pixel row in the display region, where n is a positive integer.
