Embodiment Construction

[0061] An example embodiment is a transparent antenna integrated touch screen device that can be used in touch screens (also known as touch displays) and portable mobile communication devices such as tablet computers and mobile phones.

[0062] In an example embodiment, the touch sensor device includes an electromagnetically conductive material in the form of a transparent conductive mesh. The dielectric is layered on top of the transparent conductive mesh to detect changes in capacitance due to surface touch events on the dielectric. The transparent conductive mesh can also be used as an antenna.

[0063] An example embodiment is a touch sensor device comprising: a layer of conductive material including an electromagnetically conductive element; a touch sensor controller configured to use the electromagnetically conductive element as a touch sensor; and an antenna controller configured to use the electromagnetically conductive element as a touch sensor. antenna.

Abstract

The transparent antenna integrated touch sensor device (100) can be used in touch screens and portable mobile communication devices, such as tablet computers and mobile phones. The touch sensor device (100) includes an electromagnetic conductive element (102), a touch sensor controller (104), and an antenna controller (106), the touch sensor controller being configured to use the electromagnetic conductive element (102) as a touch sensor, the antenna The controller is configured to use the electromagnetic conductive element (102) as an antenna. The electromagnetically conductive element (102) serves a touch sensor function or an antenna function at different times and non-simultaneously. The electromagnetically conductive element (102) may be arranged as a transparent conductive mesh (112), the strands of which have a thickness to appear transparent.
