Organic Light-Emitting Display Device and Driving Method Thereof
First Claim
1. 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.
