Patent ID: 8902213

Claim:
A display device, comprising: a signal line configured to supply a variable signal to pixels, the variable signal being dependent on a luminance level of an image signal, at least one of the pixels including: a capacitor; a photo-emission element; and a transistor including an input node and an output node, the input node being configured to receive the variable signal, and said one of the pixels being configured to: execute a reset operation to apply an offset voltage to the capacitor that resets a signal stored in the capacitor; execute a signal write operation to write the variable signal in the capacitor; execute a light emission operation by the photo-emission element, the light emission being dependent upon the variable signal; execute a refresh operation that applies a fixed voltage independent of the variable signal to the input node while the transistor is in a conductive state and while a fixed non-emission voltage is applied to the photo-emission element, such that the photo-emission element does not emit light; and stop conduction of the transistor at a conclusion of the refresh operation.
