Abstract

We propose a new pixel structure based on complementary 2-TFTs switching structure. This structure is capable of reduction of DC level shift by C_gs coupling and improvement of defect tolerance, so making large, high image quality TFT-LCD panel fabrication both easy and economical. The compensating characteristics for reducing DC level shift in complementary 2-TFTs switching architecture were investigated using a TFT equivalent model. However, the number of gate lines and TFTs doubles as compared with a fundamental structure without redundancy. To minimize this problem (reduction of aperture ratio), a new pixel structure called a complementary 2-TFTs structure, which has one contact hole, was proposed. This technology has a low hardware overhead and is very capable of redundancy for open circuit defects in a TFT-LCD panel.
