Description
Summary:In this paper, we successfully develop a new optical touch which is highly integrated with current structure of TFT‐LCD display. The advantages are high touch resolution, no active force, free object touch, low cost and easy integration with panel. Besides, we have set up a simulation system to predict and optimize the touch performance. In addition, the signal to noise ratio (SNR) is measured around 21 by 4″ mockup sample. A superb touch display can be achieved in the near future.
