An Integrated Driving Circuitry by Employing P-type Poly-Si TFTs for AMOLED

摘要：

Low-temperature poly-Si (LTPS) is becoming an attracted technology for the fabrication of thin film transistors (TFTs) used in active matrix organic light emissive displays (AMOLED). Because the TFT fabrication process can be simplified by p-type technology, an integrated driving circuitry employing only p-type poly-Si TFTs for AMOLED is proposed in this paper, including gate driver, data sampling driver and pixel array. The output pads of the panel are largely decreased by using a block sequential method. In this paper, an improved P-type shift register is proposed to realize line-by-line selection. And a buffer which is made up of four p-type inverters is used to enhance the driving capability of the circuitry. In order to verify the validity of the proposed scheme, circuit simulation using HSPICE has been done. The simulation result indicated that the circuitry worked well. Utilizing the advantage of Korea Seoul National University and Neo Poly me on making poly-Si TFT, we have already fabricated 96 × 3 × 128 AMOLED using the design above.
