Patent ID: 8159427

Claim:
An image display device comprising: an image displaying area including a plurality of pixels with an OLED, including one terminal which has been grounded, said pixels being formed in a matrix form; a signal drive circuit for generating a display signal voltage to be supplied to the plurality of pixels; a signal line connected between each of pixels through which the display signal voltage is inputted to each of pixels; a first voltage line connected between each of pixels through which a first voltage is supplied to each of pixels; a second voltage line connected between each of pixels through which a second voltage is supplied to each of pixels; a drive TFT, a drain terminal of which is configured to be connected to another terminal of the OLED, and a source terminal of which is configured to be connected to the first voltage line; a reset TFT, one terminal of which is connected to a gate terminal of the drive TFT, and another terminal of which is connected to the drain terminal of the drive TFT; a memory capacitor, a first terminal of which is connected to a gate terminal of the drive TFT; an input TFT, one terminal of which is connected to a second terminal of the memory capacitor, and another terminal of which is connected to the signal line; and a drive input TFT, one terminal of which is connected to the first terminal of the memory capacitor, and another terminal of which is connected to the second voltage line; wherein each of gates of the reset TFT, the input TFT and the drive input TFT is configured to be controlled by a device outside of the plurality of pixels.
