摘要： A display apparatus includes a display panel having display devices arranged in a matrix layout and driven through a plurality of row wirings and column wirings, a scanning unit to scan the row wirings, and a modulation unit to supply a modulation signal to the column wirings. A compensation unit applies compensation processing to compensate for fluctuation of display luminance due to the influence of voltage drop caused by a resistance of the row wiring to the image data, and a luminance control unit controls display luminance of the display panel based upon luminance information of the image data.

摘要： Provided are image display apparatus and image display methods capable of suitably making correction for variation of driving conditions due to an electric resistance of matrix wiring of a display panel by downsized hardware. The apparatus and methods involve a device of calculating voltage drop amounts caused by the resistance of row wires, for input image data, and a device of calculating image data with correction for the voltage drop amounts (corrected image data). An overflow processing circuit is provided so as to prevent overflow of the image data after the correction from an input range of a modulator, and the overflow is prevented by a gain. Since a gradation converter for changing a gradation conversion characteristic by a gain is provided in the stage preceding to the configuration for making the correction for influence of the voltage drop, it becomes feasible to cancel saturation characteristics of phosphors and to display images with high quality thereby.
