TRANSLUCENT TOUCH SCREENS INCLUDING INVISIBLE ELECRONITC COMPONENT CONNECTIONS
First Claim
1. A wireless communication device comprising:
- a first housing including a display and a control circuit; and
a second housing rotatable relative to the first housing between an open position and a closed position, the second housing including a touch surface that is positioned substantially parallel to the display of the first housing when the second housing in the closed position and an audio output component, the touch surface has at least semi-transparent properties so that the display of the first housing is viewable through the touch surface when the second housing is in the closed position,wherein the touch surface includes a mesh composed of a conductive material, the mesh providing audio signals from the control circuit of the first housing to the audio output component of the second housing and input signals from activation points of the touch surface to the control circuit of the first housing.

Abstract
Disclosed is a touch screen of semi-transparent mesh that may be utilized by, for example, a mobile communication device. The mesh may be utilized for both a touch screen and an electrical circuit for an electronic component attached to it. That is, the mesh may be in part a touch screen, and in part an electrical circuit. The touch surface includes mesh composed of a conductive material configured to provide input signals from activation points of the touch surface to the control circuit of the device. The mesh of a conductive material also includes an electrical circuit configured to provide audio signals from the control circuit of the device to the speaker. Since the disclosed semi-transparent mesh acts an electrical circuit, artwork to hide electrical circuits from the electronic component to the controller is not necessary. A switchable ground eliminates interference between the touch screen and the electrical circuit.
