Abstract
The disclosure relates to a pixel circuit, a method for driving method, a display panel, and a display device. The pixel circuit includes: a scan control circuit, a latch circuit, a charging control circuit, and a pixel electrode; the scan control circuit is configured to output a data signal to a first node in response to a gate scan signal; the latch circuit is configured to latch signals of the first node and a second node response to a signal of the first node; and the charging control circuit is configured to output a first display voltage signal to the pixel electrode in response to the signal of the first node and a charging control signal, and to output a second display voltage signal to the pixel electrode in response to the signal of the second node and the charging control signal.
