ABSTRACT:
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.
