Abstract:
1. A light emitting display device comprising a pixel cell formed in an area defined by a data line supplied with a data voltage, at least one scan line supplied with a scan signal, a light emission control signal line supplied with a light emission control signal, a driving voltage line supplied with a driving voltage, and a compensation voltage line supplied with a compensation voltage of a first voltage level or a second voltage level different from the first voltage level, wherein the pixel cell comprises: a light emitting element for emitting light by current; and a pixel circuit for providing current corresponding to the data voltage to the light emitting element using the data voltage, the scan signal, the light emission control signal, the driving voltage and the compensation voltage, wherein providing current corresponding to the data voltage to the light emitting element is based on the compensation voltage of the first voltage level and turning off the light emitting element is based on the compensation voltage of the second voltage level.
