Abstract (en)

A method of driving a display (600) is disclosed. The display (600) comprises an active matrix comprising a plurality of pixel circuits (100; 200), each pixel circuit (100; 200) of the plurality of pixel circuits comprising a pixel-driving transistor (102, 202), each pixel-driving transistor (102, 202) comprising a first gate (104) and a second gate (106, 206). The method comprises dimming a dimming area (602a, 602b) of the display (600) by applying a common dimming signal at the respective second gate (106, 206) of each pixel-driving transistor (102, 202) of the pixel circuits (100; 200) comprised in the dimming area (602a, 602b); and controlling a luminance level of a pixel connected to a pixel circuit comprised in the dimming area (602a, 602b) by applying a luminance signal at the first gate (104) of the pixel-driving transistor (102, 202) of the pixel circuit (100; 200).
