Abstract
In the device for voltage driving the self-luminous display element, the self-luminous display element driving device includes a circuit for generating deterioration information concerning a deterioration state of the self-luminous display element, and a circuit for adjusting a voltage applied to the self-luminous display element, on the basis of the deterioration information generated by the deterioration information generating circuit. The deterioration information generating circuit generates the deterioration information on the basis of a time, a luminance, a current value or a voltgage value, etc. The self-luminous display element may be, for example, an EL (electroluminescence) element or an organic EL element.
