Abstract
The invention provides an image display device that has an especially satisfactory display quality for animated images, and sufficiently suppresses the irregularities of display quality among pixels. The image display device includes a light emitting drive means that drives a light emitting means, based on an analog display signal inputted to the pixels, and a light emitting control switch for controlling a light-on or light-off of the light emitting means on one end of the light emitting drive means in each pixel.
Claims3
An image display device comprising:
- a pixel connects to a signal line inputting an image data signal, a reset line, a light-on switch line, an input switch line, and a power supply line, the pixel having an organic light emitting diode, an input switch controlled by the input switch line, a drive TFT to which current is supplied from the power supply line to the organic light emitting diode, a pixel capacitor arranged between the input switch and a gate electrode of the drive TFT, and a light-on switch controlled by signal on the light-on switch line,
- a signal data on the signal line is inputted to a gate electrode of the drive TFT via the input TFT switch and the pixel capacitor,
- a source of the drive TFT is connected to the power supply line, a drain of the drive TFT is connected to one electrode of the organic light emitting diode,
- the other electrode of the organic light emitting diode is connect to common terminal,
- the light-on switch is provided between the drive TFT and the organic light emitting diode,
- a reset switch which is controlled by the reset line arranged between the gate and the drain of the drive TFT, and
- a retention capacitor arranged between the gate and the source of the drive TFT.
