摘要： An object is to eliminate fixed pattern noise due to unevenness or variation of the threshold voltages in DA converters and buffer circuits, when forming a pixel portion integrated with a peripheral driver circuit, including the DA converters, by using polycrystalline Si TFT. For that purpose, a pixel common electrodes is provided independently for each of a signal line, and an output of the buffer circuit is connected to both the common electrode and the signal electrode through a switch. With this, the variation of the threshold voltages in the buffer circuits are cancelled between the common electrode and the signal electrode, thereby enabling to remove the above-mentioned fixed pattern noise therefrom.

摘要： In a display mode, a signal driving circuit (DAC) transmits image signals to the pixels selected by a scanning circuit for display and first switches of switch units. Then, a power supply circuit supplies a current corresponding to the transmitted signal to the pixels. Then, organic EL elements provided in the pixels are driven to emit light, thereby displaying an image. In order to correct the deterioration of the organic EL elements, first, a constant current flows from a current source to the organic EL elements of the pixels selected by a scanning circuit for detection and second switches and a voltage corresponding to the constant current applied to the organic EL element is detected. The detected voltage is input to an AD converter through a buffer amplifier, and the AD converter converts the voltage into a digital value, and transmits the digital value to a signal correction control unit. When the organic EL element deteriorates, the detected digital value varies. Therefore, the signal correction control unit corrects the signal from the signal driving circuit, thereby correcting the deterioration of the organic EL element.
