英文摘要	This paper introduces a touch screen technology based on infrared optical. This technology has apparent advantages in the large-size applications, which is simple, low cost, high feasibility. In the system, the detection of ambient light and the adaptive control of IR LED can effectively enhance the adaptability of the touch screen in complex light environment via the MCU. In image processing, the image of foreground and background are segmented by Otsu's method with a coefficient. Integral projection is adopted to recognize the contact area. The result shows that the performance of the system fully meets the requirements of real time and accuracy.
