ORGANIC LIGHT EMITTING DIODE DISPLAY AND DRIVING METHOD THEREOF

摘要

PURPOSE: An organic light emitting diode display device and a driving method thereof are provided to realize a BDI technique without a brightness difference due to a panel location, thereby enhancing the performance of an MPRT. CONSTITUTION: A driving TFT(DT) includes a gate electrode connected to a first node and a source electrode connected to a high potential driving voltage source. The driving TFT controls a driving current by the voltage between a source and a gate. A first storage capacitor is connected between a first node and a second node. A first switch TFT(ST1) initializes the first node at a reference voltage. A second switch TFT(ST2) samples a high potential driving voltage and the threshold voltage of the driving TFT and reflects the samples result to the first node.
