TOUCH- SENSITIVE DEVICE AND COMMUNICATION DEVICE USING THE SAME

摘要

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).
