Zusammenfassung:This disclosure provides an illumination device with integrated touch sensing capability and a manufacture method thereof. In one aspect, an illumination device with integrated touch sensor capability comprises a light guide having a metalized light-turning feature and an electrode system for sensing changes to the capacitance between electrodes in the electrode system induced by the proximity of an electrically conductive body, such as a human finger. The metalized light-turning features may be electrically connected to and/or part of the electrode system.
