Abstract:
The present application provides a display panel and a display device. The display panel includes a gate driving circuit and a plurality of rows of pixel circuits. By electrically connecting a gate of a driving transistor in each of the pixel circuits to at least one oxide thin-film transistor, each of the pixel circuits has a low leakage characteristic, thereby realizing a low-frequency driving display of the pixel circuits. On this basis, a display time interval between two adjacent rows of the pixel circuits can be lengthened about half-frame time, thereby realizing an ultra-low-frequency driving display.
