Touch-sensitive device and communication device
First Claim
1. A touch-sensitive device, comprising:
- a substrate comprising a first set of holes extending in a first direction through said substrate, wherein each hole forms an opening at a first side of said substrate,a second set of holes extending in a second direction through said substrate, wherein each hole forms an opening at said first side of said substrate, where said second direction intersects said first direction,a transmitter arranged to transmit electromagnetic radiation through said first set of holes, anda receiver arranged to receive electromagnetic radiation transmitted through said second set of holes, wherein the touch-sensitive device is arranged to detect the presence and/or position of an object on or above said first side of said substrate by detecting electromagnetic radiation reflected from said object.

Abstract
Touch-sensitive device (10) that comprises a substrate (12) comprising a first set of holes extending in a first direction (14) through said substrate (12) whereby each hole forms an opening at a first side (12a) of said substrate (12) and a second set of holes extending in a second direction (16) through said substrate (12) whereby each hole forms an opening at said first side (12a) of said substrate (12), where said second direction (16) intersects said first direction (14). A transmitter (18) arranged to transmit electromagnetic radiation through said first set of holes, and a receiver (20) is arranged to receive electromagnetic radiation transmitted through said second set of holes, whereby the touch-sensitive device (10) is arranged to detect the presence and/or position of an object (22) on or above said first side (12a) of said substrate (12).
