High reliability and low noise amorphous-silicon gate with novel clock-driving methodology
Chien-Hsueh Chiang,Yiming Li 한국정보디스플레이학회 2014 Journal of information display Vol.15 No.1
In this paper, for the first time, a novel amorphous-silicon thin-film transistor (TFT) gate drive circuit and its successfully improved dynamic characteristics are presented. Not only was the output ripple suppressed; the rate of threshold voltage shift was also reduced by up to 20%. About 50% power-saving was also estimated. The amorphous-silicon gate driver (ASG) circuit was further fabricated, and the measured results show the high practicability of the achieved design.

A short rise time, short fall time, and small ripple are required to reduce the misoperation of pixel data voltage and to improve the stable signal processing of a driver circuit. In this study, a novel amorphous silicon gate (ASG) driver circuit consisting of 15 hydrogenated amorphous silicon thin-film transistors (a-Si:H TFTs) and two capacitors was optimized using a thin-film transistor (TFT)-circuitsimulation- based multi-objective evolutionary algorithm on the unified optimization framework . The ASG circuit was optimized for the following given specifications: rise time <0.7 μs; fall time <0.6 μs; ripple peak <6.5 V; clock Ctotal <40 pf; and total TFT widths <6000 μm. The main findings of this study show that the rise time had an 18% reduction and that the fall time, total widths, and clock Ctotal had 7, 17.5, and 9% reductions, respectively.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.
