ORGANIC LIGHT-EMITTING DIODE (OLED) DISPLAY

摘要

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a plurality of pixels, each including a driving thin film transistor (TFT) formed over a substrate and including a driving gate electrode, a first storage capacitor comprising a first electrode and a second electrode, and a second storage capacitor comprising a third electrode and a fourth electrode. The first electrode is electrically connected to the driving gate electrode and the second electrode is formed over the first electrode and electrically insulated from the first electrode. The third electrode is electrically connected to the first electrode, is formed on a different layer from each of the first and second electrodes, and does not overlap the second electrode. The fourth electrode is formed over the third electrode and electrically insulated from the third electrode.
