Patent ID: 8274493

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 a passivation layer covers the active device; and a sensing electrode, disposed on the passivation layer and located at the first sensing area, wherein the sensing electrode is electrically connected to the readout line through the active device, and a portion of the scan line is located between the first sensing area and the sensing electrode to form a reference capacitor; 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 common electrode, covering a portion of the black matrix layer and the spacer, wherein there is a pitch between the common electrode on the spacer and the sensing electrode to form a sensing capacitor.
