Patent ID: 7332742

Claim:
A display device comprising: a pixel region including a plurality of pixels, a source driver, a first gate driver, a second gate driver, a plurality of gate signal lines, a plurality of source signal lines, and a control signal generating circuit, wherein each of the plurality of pixels includes a light-emitting element, a first transistor for controlling video signal input to the pixel, a second transistor for controlling whether the light-emitting element emits light or not, and a capacitor for holding the video signal, wherein each of the plurality of gate signal lines is electrically connected to the first gate driver and the second gate driver, and each of the plurality of source signal lines is electrically connected to the source driver, wherein the source driver includes a pulse output circuit, a latch circuit, and a selection circuit which operates based on a source control signal outputted from the control signal generating circuit, wherein each of the first gate driver and the second gate driver includes a pulse output circuit, and a buffer circuit which operates based on a first gate control signal and a second gate control signal both outputted from the control signal generating circuit, and wherein a potential of one of the plurality of source signal lines is changed while none of the plurality of the gate signal lines is selected.
