A touch-sensitive device that includes a touch surface circuit that facilitates a change in a coupling capacitance in response to a capacitance-altering touches occurring at the touch surface. The stereo matching system and method using a dynamic programming scheme according to the present invention may perform viterbi type stereo matching using at least two different penalty of disparity discontinuity values and synthesize the performed stereo matching results, thereby outputting a disparity map. A top surface andor a bottom surface of the panel at the optically transmissive portion is smooth and continuous to the naked eye.
