A new active matrix organic light emitting diode (AM-OLED) pixel circuit design, based on the low-temperature polycrystalline thin-film transistors (LTPS-TFTs) is proposed and verified by SPICE simulation. The voltage-programming pixel circuit is formed by five n-type TFTs. one additional control signal, and a storage capacitor. The simulation results show that this pixel circuit has high immunity to the variation of poly-Si TFT characteristics.

A novel source-follower-type analogue buffer employing LTPS TFTs is proposed for AMLCD and AMOLED. The simulation results indicate that the proposed circuit is capable of minimizing the variation from both the charging time and the device characteristics and maximizing the range of the input voltage by adding an active load and a new compensation operation.

Two types new simple source follower circuit using low-temperature polycrystalline silicon thin film transistors (LTPS-TFTs) as analogue buffer for the integrated data driver circuit of active matrix liquid crystal displays (AMLCDs) and active matrix light emitting diodes (AMOLEDs) are proposed. Analogue buffer designs are discussed and verified by SPICE simulation results.
