Capacitive Touch Sensors
To support increasingly sophisticated touchscreen functionality, Capacitive Touch sensors are becoming higher resolution. This in turn requires a greater number of silver tracks around the perimeter of each sensor. To minimise the "dead" border area around each touch panel, the width and pitch of these silver tracks is critical.
ELK is a technology leader in this area. Through refining our production processes and materials, ELK has progressively reduced the required pitch for silver tracks on our Capacitive Touch sensors. With our new roll-to-roll manufacturing lines, we already offer our customers 0.1mm pitch (0.05mm tracks with 0.05mm gaps). We are also prototyping 0.07mm pitch for mass production from mid-2011.
There is no price premium for our "fine pitch" silver tracks.
