Abstract
A display device including a display panel having a display area. The display panel includes pixel circuits located in the display area. Each pixel circuit includes a driving transistor and a voltage regulating module that is configured to adjust a node voltage of the driving transistor by a voltage provided by one voltage regulating signal line of voltage regulating signal lines. The pixel circuits have data refresh frequencies including first and second frequencies. The first frequency is greater than the second frequency. When one pixel circuit performs data refreshing at the first frequency, one voltage regulating signal line is configured to provide a first voltage, and when one pixel circuit performs data refreshing at the second frequency, one voltage regulating signal line is configured to provide a second voltage not equal to the first voltage.
