Correction of pixels in an organic EL display device
First Claim
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 that prescribes a relationship of pixel positions 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 outputs correction values for the respective pixels using the correction value formula or coefficients thereof stored in said correction value formula storage section; and
the correction value output section corrects brightness data for each pixel using the correction value from said correction value output section according to the pixel position, to thereby perform display to the respective display pixels.

3. A method of manufacturing an organic electroluminescent display device in which display pixels containing organic electroluminescent elements are arranged in a matrix, comprising:
-
selectively illuminating organic electroluminescent elements of display pixels in a predetermined plurality of small areas within a display area in which the display pixels are arranged in a matrix, and detecting a driving current for each of the small areas at this time;
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
storing correction data for correcting image data for each pixel input based on the estimated trend in non-uniformity of brightness. - View Dependent Claims (4, 5, 6)
