ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

PURPOSE: An organic electroluminescent display device is provided to display uniform image by supplying a data signal with different gamma value to each region of a pixel unit. CONSTITUTION: A data driver supplies a data signal to pixels. A timing controller(400) supplies a data control signal and image data to the data driver and includes a counter(410), first and second lookup tables(420a,420b), and a controller(430). The counter counts the synchronization signal supplied from the outside and outputs a counting signal. Different gamma values are stored in a plurality of lookup tables. The controller divides the pixel unit to several regions by corresponding to the counting signal. The controller outputs the image data with the gamma value by mapping one of the lookup tables to each region.
