摘要： In an organic EL display, correction is made for a difference in screen luminance between the case of measuring characteristics of OLED elements, and the case of not measuring the characteristics of the OLED elements. A data line for feeding image data items, and a detection line for measuring the characteristics of the OLED elements are connected to respective pixels. Detection of the characteristics of the OLED elements is executed by utilizing a specified period of a frame period. Because an image-displaying period is limited in a frame where measurement of the characteristics of the OLED element 11 is executed, the luminance undergoes deterioration. In order to prevent the deterioration of the luminance, an analog-to-digital converter ADC causes γ characteristic of the OLED elements in the frame where measurement of the characteristics of 11 is executed to be varied by the agency of a signal from a timing controller Tcon to the analog-to-digital converter ADC, thereby increasing luminance intensity of light emission of the OLED elements.

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： 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.
