Abstract

The present invention provides an analog resistive touch panel without bias, which comprises a core layer formed by electret material with piezoelectric effect, and configured with the transparent conductive layer disposed at the upper and lower side of the core layer, and each side of the conductive layer on one surface of the core layer is formed with a highly conductive metal electrode, and the transmission wire electrically connected with the electrode, and the transmission wire is electrically connected to a controller. When touching the analog resistive touch panel without bias, the piezoelectric effect of the electret material will generate the potential difference between the conductive layers on the upper and lower surfaces of the core layer, and the distances of the contact points to the conductive metal electrode on the conductive layer are different and have different resistance, so that each electrode will generate the current signal corresponding to the potential difference and the resistance, and output the current signal through the transmission wire electrically connected with the electrode to the controller, and, after correction, it could detect the positional coordinates of the contact points.
