Abstract: An image processing IC detects a fixed pattern displayed on the OEL panel within a period of time when a power supply is switched ON. A display position of the fixed pattern detected when the power supply is switched OFF is stored in a first memory, the display position of the fixed pattern stored in the first memory when the power supply is switched ON is read and sent to a driving circuit (DRV). The DRV measures element characteristics of a pixel at the display position of the fixed pattern sent from the image processing IC, compares with element characteristics of a pixel before deterioration stored in a second memory and sends a comparison result to the image processing IC. The image processing IC corrects image data input to the pixel at the display position of the fixed pattern based on the comparison result sent from the DRV.
