摘要： A self-luminous apparatus is disclosed wherein a deterioration amount difference between different pixels can be eliminated accurately to correct a sticking phenomenon while the self-luminous apparatus is used. In the self-luminous apparatus, a deterioration amount difference appearing between a correction object pixel and a reference pixel within a first light emission period of time is calculated first using a deterioration ratio derived from gradation values of the pixels. Then, a deterioration ratio for correction for the correction object pixel necessary to eliminate the calculated deterioration amount difference within a second light emission period of time is derived using a deterioration ratio of the reference pixel. Thereafter, the derived deterioration ratio for correction is converted into a corresponding gradation value, and the correction object pixel is driven to emit light with the converted gradation value.

摘要： The prior art power consumption control techniques convert the video signal (gray level) in one way or another based on the estimated power consumption level. The present invention proposes a power consumption controller which includes (a) a power consumption calculation section which sequentially calculates the power consumption level of a self-luminous display device based on a video signal input from the beginning of each frame up to the time of calculation, (b) a power consumption status determination section which determines whether the calculated power consumption level exceeds a reference value for comparison by constantly comparing the two levels. If this is the case, the same section detects the timing at which the power consumption exceeds the reference value for comparison and (c) a peak brightness control section which controls the peak brightness of the self-luminous display device if the power consumption level exceeds the reference value for comparison based on the detected timing.
