Abstract:
1. An image display device comprising: a gate drive circuit; and pixels, each of which comprises a light emitting device, a pixel capacitor, a drive transistor, a reset transistor, and a light-on transistor; wherein a signal line is connected through the pixel capacitor to a gate of the drive transistor; a source of the drive transistor is connected to a power supply line; a drain of the drive transistor is connected to one end of the light emitting device through a source-drain path of the light-on transistor; a gate of the light-on transistor is connected to a light-on line; the other end of the light emitting device is connected to a common terminal; a source-drain path of the reset transistor is connected between the gate and the drain of the drive transistor; a gate of the reset transistor is connected to a reset line; and during a write period, a signal voltage is inputted into the signal lines, the gate drive circuit controls the reset line and the light-on line so that reset transistor is turned ON after the light-on transistor is turned ON, and then the reset transistor is turned OFF after the light-on transistor is turned OFF.
