Method of driving display panel, luminance correction device for display panel, and driving device for display panel

A method of driving a display panel, comprising:

• setting a pixel luminance value to a target luminance setting value at least three times at predetermined time intervals with a luminance setting value determined from measured luminance information of pixels during successive video blanking periods;
• and
• carrying out luminance correcting operations such that each of the time intervals between the luminance correction operations differ, whereby the starting interval of recorrection operation is varied, wherein the intervals between the luminance correction operations are varied according to the luminance degradation characteristics of display elements.

A method of driving a display panel wherein pixels are driven, luminance information is captured from the pixels and measured, correction values are calculated from the measured luminance information and a luminance setting value, the correction values are stored in a correction memory, and a driving amount is corrected in accordance with the correction memory, the method comprising:

• carrying out a series of renewal operations on the correction memory for all of the pixels at least two times at predetermined time intervals, wherein the luminance setting value is determined from measured luminance information of the pixels during successive video blanking periods.
