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.

Abstract: A Liquid Crystal Display (LCD) panel includes a pixel array, a scanning line driver, a common electrode driver, and a data line driver. During a current frame, the scanning lines receive a scanning signal. The common electrode driver applies a common electrode signal to the common electrode line during a time window in which the scanning line corresponding to the common electrode line receives the scanning signal. The data line driver applies a data signal to the data lines during a time window in which the scanning line driver outputs the scanning signal. The data signals of adjacent pixel rows have opposite polarities, the common electrode signal during the current frame is opposite to the common electrode signal during a next frame, and the data signals of the pixel row in the current frame have opposite polarities of the data signals applied on the pixel row during the next frame.
