ORGANIC LIGHT EMITTING DISPLAY APPARATUS AND DRIVING METHOD THEREOF

摘要

An organic light emitting display device according to an embodiment of the present invention comprises: a display unit which includes a first pixel and a first data line connected to the first pixel; a comparison unit which compares first image data corresponding to the first pixel in input image data input from the outside, with a first threshold gradation value and a second threshold gradation value; a data determination unit which determines, when the first image data is equal to or more than the first threshold gradation value and less than the second threshold gradation value, any one of the first threshold gradation value and the second threshold gradation value as first correction image data; a source driver which outputs a data signal corresponding to the input data, to the first data line; and an output unit which outputs the first correction image data to the source driver.
