Light-emitting display and method of driving the same

Abstract:

The present invention provides a light-emitting display including a display panel, a power supply part, a data driver, a first compensation circuit, and a second compensation circuit. The display panel includes a pixel. The power supply part is connected to a power supply line of the pixel. The data driver is connected to a data line of the pixel. The first compensation circuit section obtains a sensed value through a sensing line of the pixel and obtains a voltage value through the power supply line. The second compensation circuit which generates a compensation value for compensating degradation of an organic light-emitting diode included in the pixel, based on the sensed value and the voltage value.
