Abstract:
1. An organic electroluminescent display device in which display pixels containing organic electroluminescent elements are arranged in a matrix, comprising: a correction value formula storage section for storing a correction value formula or coefficients thereof and in response to the pixel positions providing correction values for display and brightness correction data of those pixels; a correction value output section for receiving the input of data for the positions of respective pixels, and correction values produced by the correction values formula storage section; the correction value output section corrects brightness data for each pixel using the correction value and the pixel position, and to display the corrected display pixels; an emission controller for selectively illuminating organic electroluminescent elements of display pixels in a predetermined plurality of small areas within the display area wherein display pixels are arranged in a matrix; a current detector for detecting a driving current for each of the small areas at the time of selective emission of the small areas; a correction value formula generator for estimating a trend in non-uniformity of brightness of the respective pixels in the overall display area based on the detected driving current for each of the small areas and determining said correction value formula or coefficients thereof based on the estimated trend in non-uniformity of brightness; and wherein the correction value formula, or coefficients thereof, determined by said correction value formula generator is stored in said correction value formula storage section.
