摘要:
It is an object of the present invention to inhibit a collapse of a color balance possibly caused due to deterioration of self-emission elements when performing a color displaying by virtue of several different colors. A self-emission display apparatus comprises: a display element section consisting of self-emission elements; a monitor element section consisting of self-emission elements of different colors formed in the same manner as the self-emission elements of the display element section; a power supply circuit which supplies driving voltages to the display element section; monitor detecting units for detecting an operating state of the monitor element section; driving voltage control units which control driving voltages in accordance with a detected operating state; and a display control section for supplying display signal to the display element section. Further, the self-emission display apparatus has monitor control units which perform lighting controls of the foregoing different colors on the monitor element section, as well as a monitor load adjusting unit which adjusts a load state of each of the foregoing different colors in lighting control so as to maintain a color balance of the display element section.
