Patent ID: 8159466

Claim:
A touch panel, comprising: a first substrate; a plurality of pixel structures, arranged on the first substrate in an array, wherein at least one first pixel structure in each M×N pixel structures comprises a first sensing area, where M and N are positive integers, and the first pixel structure comprises: an active device, disposed on the first substrate and located at the first sensing area, wherein the active device is electrically connected to a scan line and a readout line, and is covered by a passivation layer; a first sensing electrode, disposed on the passivation layer and located at the first sensing area, wherein the first sensing electrode is electrically connected to the readout line through the active device; and a second sensing electrode, disposed on the passivation layer and located at the first sensing area, wherein a portion of the scan line is located between the first sensing area and the second sensing electrode, and is electrically connected to the second sensing electrode; a second substrate, having a second sensing area corresponding to the first sensing area; a black matrix layer, disposed on the second substrate and located at the second sensing area; a spacer, disposed on the black matrix layer and located at the second sensing area; and a floating electrode, covering a portion of the black matrix layer located at the second sensing area and the spacer, wherein the floating electrode on the spacer respectively has a same pitch relative to vertical directions of the first sensing electrode and the second sensing electrode.
