Abstract:
1. A method of compensating for luminance of an organic light emitting diode display, which has a pixel matrix including a first pixel of a first color and a second pixel of a second color, the method comprising the steps of: generating feedback currents including a first feedback current for compensating for luminance of the first pixel of the first color and a second feedback current for compensating for luminance of the second pixel of the second color, the feedback currents generating step comprising: generating a first compensating voltage according to the first feedback current and generating a second compensating voltage according to the second feedback current; compensating for luminance of the first and second pixels by at least adjusting a first data current applied to a first data line for driving the first pixel and a second data current applied to a second data line for driving the second pixel according to the first compensating voltage and the second compensating voltage respectively.
