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： An image display with high brightness where a long time can be secured for light emission of self-luminous elements can be implemented using only line memories.The period for the writing in of a display voltage (period for writing in of data) continues for a number of lines (three lines), and the reset pulse becomes of a “high” state. Subsequently, operation for three lines is carried out collectively during a triangular wave period (period for writing in of a triangular wave voltage), and only the light emission controlling pulse becomes of a “high” state. During the period for the writing in of a triangular wave voltage, the writing in of a triangular wave voltage from the second time onward is rewriting of a triangular wave voltage, and thus, the period for rewriting the display voltage (dotted line portion) becomes unnecessary, and a longer period for light emission, where the light emission controlling pulse becomes of a “high” state, can be secured.

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.
