Abstract

Projected capacitive touch screen has the advantage of wear-resistant, high transmittance, long life, low power consumption, high sensitivity, noise rejection capability and support for multi-touch .This paper studies the related technologies of projected capacitive touch screen system: full touch point detection technology of mutual capacitance, gravity method to locate the touch point of the finger, IIR digital filter to improve the signal to noise ratio, bilinear interpolation method to achieve the rotation and scaling of the image.
