20120062509CAPACITIVE TOUCH PANEL - A capacitive touch panel has a substrate, a medium layer and multiple leading wires. The medium layer is formed on the substrate and has a rough surface, two sense units arranged along two different axial directions, and each sense unit has multiple touch points. The leading wires are formed on the leading wire segment of the medium layer are and electrically connected with the touch points of the sense units. Accordingly, the leading wires can be securely combine with the leading wire segment of the medium layer due to the arrangement of the rough surface and can be kept from detaching from the medium layer.03-15-2012
20120007812TOUCH PANEL - A touch panel has a test point formed on one end of each of the wires formed inside the touch panel and connected to a circuit board. The test point is larger than a wire diameter of the wires and serves to be contacted by a probe of a test instrument. Even if the probe is similar to the wires in width, the wires are not cut and broken by the probe. Accordingly, after the wires of the touch panel are tested by a probe-type test instrument, the touch panel can still operate normally without having the fault arising from the broken wires inadvertently cut by a probe.01-12-2012
20110298749MUTUAL CAPACITANCE TOUCH PANEL - A mutual capacitance touch panel has an at-least-95% overlap rate of area between each upper sensing area of an upper sensing unit mounted thereon and a corresponding lower sensing area of a lower sensing unit mounted thereon. Given such layout, the mutual capacitance touch panel has an error between detected touch points and actually touched points controlled within a smaller range. Accordingly, the mutual capacitance touch panel has enhanced touch accuracy.12-08-2011
20110267286TOUCH PANEL - A touch panel has a pattern layer which designates positions of sensing areas respectively activating specific functions after being pressed, and is mounted on a top surface or a bottom surface of a lower substrate. As the substrates and sensing units mounted on the substrates are all transparent, the pattern layer can be visible when seen from the top surface of the touch panel. When the position of the pattern layer is pressed by a finger, the sensitivity upon pressing the pattern layer can be enhanced, since the pattern layer does not get in the way between the finger and the sensing unit.11-03-2011
20110234533Capacitive Touch Panel - The present invention is related to a capacitive touch panel having a substrate having multiple conductive wires mounted on a top of the substrate. The capacitive touch panel further has a hard film layer mounted on the top of the substrate and having an opaque ink layer mounted on a periphery of a top of the hard film layer, the opaque ink layer covering the conductive wires. The present invention mounts the ink layer directly on the hard film layer without using any conventional top cover layer and adhering layer so that the manufacturing processes are simplified and the material costs are reduced. Furthermore, a total thickness of the capacitive touch panel is decreased.09-29-2011

20110157845TOUCH PANEL - A touch panel is characterized in that one side of a top panel protrudes beyond a side of a bottom panel, signals of sensing areas or conductive layer on the top panel for sensing capacitive variation or voltage variation are transmitted to a bottom surface of the protruded side, signals of sensing areas or conductive layer on the bottom panel for sensing capacitive variation or voltage variation are transmitted to a bottom surface of the top panel through conductive adhesives and to the bottom surface of the protruded side, and the top panel has a flexible PCB formed on the bottom surface of the protruded side to receive those signals. As the flexible PCB is not sandwiched between the top and bottom panels, all layers of the touch panel can be uniformly and tightly bonded and touch insensitivity caused by air penetration into the touch panel can be prevented.06-30-2011
20110147192PROJECTED CAPACITIVE TOUCH PANEL - A projected capacitive touch panel has an upper substrate and a lower substrate. The upper substrate has multiple upper conducting layers, and each upper conducting layer has multiple upper sensor units serially connected. The upper substrate further has an insulating ink layer being non-transparent, formed on a perimeter of the bottom of the upper substrate, covering an edge of the upper sensor unit located on one end of each upper conducting layer in a direction, overlapping with the lower ports and the lower wires of the lower substrate, and having multiple reserved slots, each formed through a portion of the insulating ink layer overlapping with a corresponding upper sensor unit, and multiple conductors, each mounted in a corresponding reserved slot. The insulating ink layer masks the wires and ports on the lower and upper substrates, thereby eliminating the use of a masking cover, saving the cost and thinning the product.06-23-2011
