Patent ID: 8049735

Claim:
A touch panel, comprising: a first substrate comprising a plurality of sensor regions and a plurality of non-sensor region, the non-sensor region having a plurality of first regions and a plurality of second regions, the first substrate in the first regions of the non-sensor regions having a first thickness, the first substrate in the sensor regions having a second thickness, the first substrate in the second regions of the non-sensor regions having a third thickness, wherein the first thickness is greater than the second thickness, and the second thickness is greater than the third thickness; and a second substrate disposed facing the first substrate, the second substrate comprising a plurality of first photo spacers, a plurality of second photo spacers and a plurality of third photo spacers disposed on the second substrate facing the first substrate, the first photo spacers, the second photo spacers and the third photo spacers having substantially the same height, the first photo spacers being structurally connected to the first substrate in the first regions of the non-sensor regions, the second photo spacers being positioned corresponding to the first substrate in the sensor regions to form a first gap between the second photo spacer and the first substrate in the sensor region, the third photo spacers being positioned corresponding to the first substrate in the second region of the non-sensor regions to form a second gap between the third photo spacer and the first substrate in the second region of the non-sensor region, wherein the second gap is larger than the first gap.
