摘要： The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.

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.

摘要： With the use of pixel control parts for controlling display elements in response to display data using a display-use voltage source and display control parts for supplying the display data to the pixel control parts, the display data is displayed on a display part. Further, the display data is corrected by detecting states of the display elements. A voltage of the display-use voltage source is preliminarily set to a fixed higher voltage, and a gray scale of the display data is elevated in response to a degradation state of the display element. Accordingly, it is possible to perform a display while maintaining the maximum brightness even when the display element is degraded. Further, the contrast can be maintained by correcting the gray scales of the display data by performing only the digital calculation.
