Abstract
The present disclosure provides a pixel compensation circuit, a scan driving circuit and a display panel. The compensation circuit includes a first switch, its control terminal connecting to the first scanning signal, its first terminal connecting to the reference voltage, its second terminal connecting to the second terminal of the driving switch; a second switch, its control terminal connecting to the second scanning signal, its first terminal connecting to the data voltage, and its second terminal connecting to the control terminal of the driving switch and the second terminal of the first switch; a third switch, its control terminal connecting to the second scanning signal, its first terminal connecting to the voltage terminal, and its second terminal connecting to the first terminal of the driving switch, so as to eliminate the influence of the threshold voltage, improve panel display uniformity, brightness and luminous efficiency.
