An active-matrix organic light-emitting diode (AMOLED) display based on the polycrystalline silicon backplane technology has been fabricated that employs a new pixel circuit to compensate for the variation in the threshold voltage of the thin film transistors (TFT). The new pixel circuit also copes with the voltage drop in the supply line and a very high contrast ratio can be achieved. The uniformity of the new AMOLED display is remarkably improved compared with the basic two-TFT pixel structure, and it can be readily applied in the mass production of commercial AMOLED displays.
