Gate driving circuit (GOA) design is critical to reduce the production cost and narrow border TFT-LCD. The proposed GOA circuit has the optimized TFT W/L design and TFT stress reduction which enhances gate driver reliability for TV application. We developed 50UHD 120Hz TFT-LCD with GOA circuit using 4-mask a-Si TFT.
