Abstract:
A drive method of an EL display apparatus that includes a switching element that turns on and off a current path between a driver transistor and an EL element. The drive method aggregates image data input to the EL display apparatus, and determines a period to turn off the switching element according to an amount of the aggregate data. With the method, suppression of peak current and expansion of contrast and so on is realized.
