ERROR COMPENSATOR AND ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent display device which can have an improved image quality.SOLUTION: The organic electroluminescent display device includes: a pixel 140 which has a driving transistor and an organic light-emitting diode; and a sensing unit 170 which extracts at least one of first information including a threshold voltage of the driving transistor and second information including degradation information of the organic light-emitting diode, from the pixel 140. The sensing unit 170 includes an amplifier 180 for amplifying a voltage corresponding to the at least one of the first information and the second information and an error compensator 190 for compensating for error components of elements included in the amplifier 180 and the error compensator itself.
