Patent ID: 8299985

Claim:
An organic light-emitting display device comprising: a light-emitting unit having a plurality of OLEDs (organic light-emitting diodes) to emit light; a light-emitting level setting unit, wherein the light-emitting level setting unit sets a light-emitting level depending on a light-emitting area and/or a change in a light-emitting degree of the light-emitting unit; a look-up table in which data for the light-emitting degree of the light-emitting unit that corresponds to each light-emitting area for each light-emitting level is set and stored; and a light-emitting control unit capable of controlling the light-emitting area and the light-emitting degree of the light-emitting unit depending on a light-emitting level with reference to the data set on the look-up table when displaying an image contained in a next frame, wherein a power consumption of the light-emitting unit at a light-emitting area ratio less than 20% increases in proportion to the light-emitting area, wherein a power consumption of the light emitting unit at a light-emitting area ratio more than 20% remains at a constant value less than a predetermined value regardless of the light-emitting area, wherein the data for the light-emitting degree stored in the look-up table contains a maximum light-emitting time and/or maximum amount of light-emitting according to them light-emitting area of the light-emitting unit, and wherein the data for the light-emitting degree stored in the look-up table is set such that the maximum light-emitting time and/or maximum amount of light-emitting of the light-emitting unit decreases as the light-emitting area of the light-emitting unit increases for the same light-emitting level.
