ABSTRACT:
An organic light emitting display capable of controlling brightness responsive to a user request. The display includes a brightness controller for controlling the brightness of a display region. The brightness controller includes a first look up table for storing widths of emission control signals corresponding to the image data of one frame period and a second look up table for storing at least one outside input mode for changing the widths of the emission control signals responsive to the outside input modes. By forming virtual look up tables, it is possible to vary the outside input modes in response to a user request in order to change the brightness of the display region while saving memory. Controlling the brightness of the display region also allows reducing power consumption, preventing the eyes of a user from getting tired, and maintaining image contrast of the display region.
