現在面板驅勢多偏重於輕巧與高解析度，但是市場需要高競爭力的產品，效能已經不是最大考量，本論文所提電路是用便宜的非晶矽薄膜電晶體製程(Amorphous Silicon Thin Film Transistor，簡稱A-Si)設計出高解析度且輕巧的液晶面板並用負偏壓原理來延長產品生命週期，在奈米製程中雜訊一直是影響電路的重要因素，因此本電路技術有全時間抗雜訊功能來穩定訊號輸出。
　　本論文設計面板的閘極（掃描線）驅動電路，電路架構包含：輸入端、共用型預驅動電路、全時段雜訊清除器以及掃描線輸出部件，其中共用型預先驅動電路主要功能為大幅縮小晶片面積，達成在27吋面板窄邊框規格 < 3mm；其中的全時間雜訊清除器由正半週、負半週抗雜訊電路組成，以達到全時間抗雜訊功能；並於準備模式中讓負責輸出的電晶體其VGS保持負偏壓延長產品生命。

Nowadays, the panel drivers tend to focus on light weight and high resolution. However, the market needs highly competitive products. The performance is not the biggest consideration. The proposed circuit is to use a cheap amorphous silicon thin film transistor (A-Si) to design a high-resolution and lightweight LCD panel and use a negative bias principle to extend the product life cycle. In the nano-process, noise is always an important factor affecting the circuit, so my proposed circuit has full-time anti-noise function to stabilize the signal output.
This paper designs the gate (scanning line) driver circuit of the panel. The circuit architecture includes: input terminal, shared pre-driver circuit, full-time noise cleaner and scan line output component. The main function of the shared pre-driver circuit is significantly reduce the chip area to achieve a narrow frame size of <3mm on the 27" panel; the full-time noise cleaner consists of a positive half-cycle and a negative half-cycle anti-noise circuit to achieve full-time anti-noise function; In the standby mode, the transistor responsible for the output maintains its VGS with a negative bias to extend the life of the product.
