Patent ID: 8736525

Claim:
A display device comprising pixels arranged in a matrix form, each pixel comprising a coupling capacitor having one end directly connected to a data line; a selection transistor, having one end directly connected to a second end of the coupling capacitor, and which is switched ON and OFF by a selection line connected to a control terminal; a driving transistor, having a control terminal directly connected to the other end of the switching transistor, and one end connected to a power supply; a light emission control transistor, having one end directly connected to another end of the driving transistor, and being turned ON and OFF by a light emission control line; a current driven type light emitting element directly connected to another end of the light emission control transistor; a storage capacitor which connects a control terminal of the driving transistor and the one end of the driving transistor that is connected to the power supply; and a reset transistor that is directly connected to the one end of the light emission control transistor, the one end of the selection transistor, and the second end of the coupling capacitor, wherein the reset transistor is turned ON and OFF by a reset line; and a driver for controlling potential of each line; wherein this driver writes a data voltage, corresponding to a gradation signal supplied to the data line, to the storage capacitor via the coupling capacitor, and with the selection transistor and the light emission control transistor in an off state and the reset transistor turned on, writes a compensation voltage according to mobility of the driving transistor to the coupling capacitor.
