ABSTRACT:
An organic EL display having organic EL elements disposed in a matrix as luminescent pixels is provided, comprised of a summation data detection unit for detecting a summation signal level of a respective original source signal to drive a respective luminescent pixel, and a panel control unit for controlling a luminescing period of the respective luminescent pixel in accordance with a summation signal level (digitally, a summation data) corresponding to one field (one frame). The panel control unit with a built-in lookup table for converting the summation data of one field to luminescing periods determines a luminescing period of respective organic EL elements in response to the summation data corresponding to one field by referring to the lookup table. Thereby, contradicting conditions for improving contrast and reducing power consumption are satisfied simultaneously without depending on the properties of the organic EL elements.
