Patent ID: 7633564

Claim:
A touch panel for a display device having a driver IC, comprising: upper and lower substrates; first and second transparent electrodes on opposing surfaces of the upper and lower substrates; first and second metal electrodes being electrically connected to the first transparent electrode in the periphery of the first transparent electrode along a first direction, and third and fourth metal electrodes being electrically connected to the second transparent electrode in the periphery of the upper and lower sides on the second transparent electrode along a second direction substantially perpendicular to the first direction; a flexible printed cable having a plurality of signal applying lines extended from the upper and lower substrates to a rear side of the display device for applying signal voltages to the metal electrodes, wherein the flexible printed cable has a first bend over an edge of the upper and lower substrates from a top to a bottom of the display device, and has a first part extended from the edge of the display device to connect the signal applying lines to the plurality of metal electrodes, a second part extended from the first part and overlaps the driver IC, and a plurality of through-holes between the first part and the second part, wherein the driver IC is arranged on the rear side of the display device for driving the display device and a portion of first signal applying lines of the plurality of signal applying lines on a lower surface of the first part of the flexible printed cable connects to a portion of the first signal applying lines of the plurality of signal applying lines on an upper surface of the second part of the flexible printed cable through the plurality of through holes before the flexible printed cable overlaps the driver IC, wherein the flexible printed cable extends in a first direction from the first bend to overlap the driver IC and the flexible printed cable has a second bend to extend past the driver IC in a second direction over a printed circuit board and connects to a touch panel controller, so that the signal applying lines are not contacted with the driver IC.
