A touch screen panel (TSP) embedded 12.1‐inch LCD employing a standard a‐Si:H TFT‐LCD process has been successfully developed. Compared with conventional touch screen panels, which use additional components to detect touch events, the new TSP exhibits a clearer image and improved touch feeling, as well as enabling the LCD module to provide the sensing data through the driver ICs with an integrated readout function. Our new internal digital switching TSP can be fabricated with low cost because it does not require any additional components compared to a standard a‐S:H TFT LCD.
