ORGANIC LIGHT EMITTING DIODE DRIVER

摘要

PURPOSE: An organic light emitting diode driver is provided to compensate a pixel in real time by compensating the deterioration of a pixel according to the comparison result of data included in a test signal. CONSTITUTION: A conversion unit(110) selectively converts input data into compensation data to the deterioration of a pixel. A test signal generator(120) supplies a test signal. A driving unit(130) drives a pixel unit having a plurality of pixels according to the compensation data of a conversion unit. A compensation unit(160) supplies deterioration compensation signal to the conversion unit according to the deterioration information detected from the pixels. The compensation selection unit selects the compensation according to the correction of the input data.
