Abstract:
1. A method of driving a display that includes a pixel array part, a scanner part, and a selector part, the pixel array part including scan lines, signal lines, first potential lines supplying a potential V CC , second potential lines supplying a potential V ofs , and a matrix of pixels, the selector part supplying a video signal V sig to the signal lines, the scanner part supplying a control signal to the scan lines to sequentially scan the pixels, at least one of the pixels including a sampling transistor, a first capacitor, a drive transistor, a first switching transistor, a second switching transistor and a light-emitting element, the method comprising: initializing a potential difference of the capacitor to V causing the potential difference of the capacitor to approach a threshold voltage V setting the potential of the gate of the driving transistor to V supplying an emitting current to the light-emitting element via the second switching transistor and the drive transistor, wherein the sampling transistor, the drive transistor, the first switching transistor, and the second switching transistor are p-channel type transistors, and wherein the light-emitting element is configured to emit light with a luminance dependent upon V
