ORGANIC EL DISPLAY DEVICE, METHOD OF CONTROLLING ORGANIC EL DISPLAY, AND ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To control the optimum brightness to each of organic EL elements without receiving an influence of a difference of change caused by temperature of emission brightness-application voltage characteristics of each of the organic EL elements.

SOLUTION: Each of a high brightness display pixel and a low brightness display pixel based on detection output of each light receiving element of a light receiving element group 38 performs: detecting a change part of the emission brightness with an emission brightness change detection part 508; detecting individual temperature change parts of a pixel based on the detection output of a temperature detection part 40 using the same organic EL element as the pixel as a detection element with a temperature change detection part 311; correcting temperature by normalizing (converting) the individual temperature change parts of the pixel to a brightness value La of the high brightness display pixel and a brightness value Lb of the low brightness display pixel corresponding to the brightness change parts on each of the high brightness display pixel and the low brightness display pixel with a data normalizing processing part 312; and controlling the emission brightness of the organic EL element so that contrast is constant by using the brightness values La, Lb obtained by the temperature correction.
