P‐5.19: Improving the Key Specifications Performance of A‐Si LCD Research

In the competitive automotive market, A‐Si Liquid Crystal Display (LCD) products are gradually losing their cost and performance advantages. Consequently, reducing costs while enhancing critical specifications has become a major challenge for A‐Si LCDs. To address this, we employed Triple Gate technology to cut back on costs, but encountered the issue of relatively low optical performance. To overcome this challenge, we conducted a Design of Experiments (DOE) using a 2^k Full Factorial Design. Through this approach, we constructed a non‐linear mathematical model with multiple objectives and identified optimal solutions for key factors. Our experimental results demonstrate a 15.4% enhancement in contrast ratio (CR) and a 5.4% increase in transmittance (TR). Typical CR values reached 1500, while TR achieved a typical value of 3.9%. Ultimately, these significant improvements in CR and TR have greatly strengthened the market competitiveness of A‐Si LCDs.
