Abstract
An organic light emitting display device that mitigates a connection restriction between a timing controller and a memory is disclosed. The organic light emitting display device comprises a display panel on which organic light emitting diodes and driving transistors that drive the organic light emitting diodes are arranged; a data driver that generates sensing data based on respective threshold voltages of the driving transistors and respective degradation levels of the organic light emitting diodes; a timing controller that generates compensation data, which may be used to perform external compensation and blur compensation, based on the sensing data and outputs the compensation data; a bridge circuit that receives the compensation data from the timing controller; and a memory that receives the compensation data from the bridge circuit. The bridge circuit and the memory are packaged in a source printed circuit board. The bridge circuit receives a clock generated within the timing controller, a command input from an external host system, and the compensation data in a differential signal mode.
