- Abstract
- In this paper, 2.2-inch qVGA LTPS(Low Temperature Poly-Si) TFT-LCD panel driven by external output buffers is proposed to reduce the display system cost. The LTPS panel with external output buffers improves the yield because only the digital functions are integrated on the LTPS panel. This also achieves a small number of interconnection lines between external IC and the LTPS panel. Finally, display system cost can be reduced by lowering the cost of flexible PCBs(Printed Circuit Boards). Moreover, the proposed panel adopts 1:6 de-multiplexing scheme for decreasing the height of the source driver circuitries. Compared with the conventional structure of 1:3 de-multiplexing scheme, the height of the source driver area is reduced as much as 40%.
