DISPLAY PANEL DRIVING CIRCUIT AND DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a display panel driving circuit capable of making display free of unevenness by correcting the nonuniformity of luminance due to a difference in the resistance etc., of a row line and column line of a display panel and to provide a driving method.

SOLUTION: Such correction data to attain the same luminance by increasing or decreasing the driving time for light emitting elements varying in the luminance on the basis of the light emitting element EL outputting the average luminance when the image data of the same luminance level is given is set, and is previously stored in a pixel display correction data storage section 50. The actual image data for the one line component stored in a frame memory 40 and the corresponding correction data for the one line component stored in the pixel display correction data storage section 50 are read out and are added by each pixel in a timing generation section 60 and the on-off of each driving switch 12 of a column driver 10 is controlled with the pulse width modulation signal by the result of the addition as a control signal.
