Abstract

In this study, the integrated circuit (IC) implemented by amorphous silicon (α-Si) thin-film transistors (TFTs) on the glass substrate was investigated. The target was aimed at the reliable design for the gate driver on the liquid crystal display (LCD) panels. In this design, the lifetime of TFT gate driver IC was tried to be improved. For practical considerations, single power supply voltage with single clocking scheme was specified in this TFT IC. In order to overcome the V_TH shift of the vulnerable α-Si TFT, the dual pull-down structure was employed for critical parts. In this paper, both measurement and simulation results will be illustrated to demonstrate the performances of our circuits. With the obtained results, a system on a panel (SOP) is promising by α-Si TFT ICs.
