摘要： A driving device for driving an image display system, which sequentially receives input image data corresponding to gradation of each pixel of a display image and outputs a driving voltage signal includes: an operation section for obtaining output image data of which a bit number is smaller than a bit number of the input image data based on input image data of a target pixel to be processed and input image data of a pixel in vicinity of the target pixel; a reference voltage generation section for generating a plurality of reference voltages of different levels; and a reference voltage selection section for selecting one of the plurality of reference voltages. The operation section is configured to obtain output image data of the target pixel so that a difference between the input image data and output image data of the target pixel and a difference between the input image data and output image data of the pixel in vicinity of the target pixel cancel out each other.

The anode drive circuit includes: a capacitor; two switches for permitting the capacitor to store charge by applying a charge voltage to a high-voltage terminal of the capacitor while holding a low-voltage terminal of the capacitor at a reference voltage; and two switches for permitting the capacitor to release charge stored therein by connecting the high-voltage terminal to an anode of an organic EL element while applying a voltage higher than a light emission threshold voltage of the organic EL element to the low-voltage terminal. The number of times of repetition of charge/discharge of the capacitor within one horizontal time period is controlled so as to control the light emission luminance of the organic EL element according to a data signal.
