A TOUCH SCREEN WITH MUTUAL CAPACITANCE

摘要

A touch screen with mutual capacitance comprises a touch substrate, a metal support, an insulating layer and at least two transparent conductive thin film layers. The metal support layer comprises a lateral support and a longitudinal support which the two supports are perpendicular to each other and not on the same plane; The insulating layer is sandwiched between the lateral support and the longitudinal support; The transparent conductive thin film layers comprises lateral and longitudinal transparent conductive thin film layer. A lateral electrode is formed by electrically connecting the lateral support with the lateral transparent conductive thin film layer, a longitudinal electrode is the same made. The RC loading will be reducing with the signal transmitting by the metal support layer, so that the lateral and longitudinal transparent conductive thin film layers can be made larger to suitable for the large-size touch screen with mutual capacitance.

1. A touch screen with mutual capacitance, comprising:
a touch substrate; a metal support layer mounted under the touch substrate, the metal support layer comprising a lateral support and a longitudinal support which the two supports are perpendicular to each other and not on the same plane; an insulating layer sandwiched between the lateral support and the longitudinal support; and at least two transparent conductive thin film layers comprising a lateral transparent conductive thin film layer and a longitudinal transparent conductive thin film layer, a lateral electrode made by the electrically connecting the lateral support with the lateral transparent conductive thin film layer, a longitudinal electrode made by the electrically connecting the longitudinal support with the longitudinal transparent conductive thin film layer, the lateral transparent conductive thin film layer being covered along the lateral support, and the width of the lateral transparent conductive thin film layer being larger than the lateral support in the vertical direction, the longitudinal transparent conductive thin film layer being covered along the longitudinal support, and the width of the longitudinal transparent conductive thin film layer being also larger than the longitudinal support.
