Patent ID: 8670008

Claim:
An organic light emitting display device, comprising: pixels connected to corresponding scanning lines and corresponding data lines; a scanning driver for supplying scanning signals to the scanning lines; a data driver for supplying data signals to the data lines; and a data processor for generating a luminance look-up table corresponding to a likelihood of burn-in for the pixels, for generating output data from input data corresponding to the look-up table, and for supplying the output data to the data driver; wherein the data processor comprises: a frame memory for storing the input data; a data comparer for generating comparison values by comparing previous input data stored in the frame memory with current input data supplied from the outside, wherein the data comparer is configured to increase the comparison value when the current input data is larger than a first reference value or when an absolute value obtained by subtracting the previous input data from the current input data is smaller than a second reference value; a control value generator for venerating a first control value and a second control value corresponding to the comparison values; a look-up table generator for generating the luminance look-up table corresponding to the first control value and the second control value; and a luminance controller for generating the output data corresponding to the luminance look-up table.
