Touch‐screen panel integrated into 12.1‐in. a‐Si:H TFT‐LCD

— A touch-screen-panel (TSP) embedded 12.1-in. LCD employing a standard existing a-Si:H TFT-LCD process has been successfully developed. Compared with conventional external touch-screen panels, which use additional components to detect touch events, the new internal TSP exhibits a clearer image and improved touch feeling, as well as increased sensing speed using discrete sensing lines to enable higher-speed sensing functions including handwriting. The new internal digital switching TSP can be fabricated with low cost because it does not require any additional process steps compared to a standard a-Si:H TFT-LCD.
