Abstract: A substrate of a touch panel has a body, a dielectric layer and multiple wires. The dielectric layer is formed on the bottom surface of the body and has multiple sensing areas and a wiring area. The wiring area is formed around the sensing areas and has multiple rough surfaces formed on the wiring area and being identical to the sensing areas in number. The wires are identical to the sensing areas in number. Each wire is formed on one of the rough surfaces of the wiring area and is electrically connected with one of the sensing areas. The formation of the wires on the respective rough surfaces can enhance adhesion of the wires so that the wires do not easily come off or get fractured.

Abstract: A resistive touch panel has an upper module, a lower module and a spacer. The upper module has a substrate, an upper touch layer, a top insulation, two upper electrodes and two conductive layers. The two conductive layers are respectively mounted on the two sides of the upper touch layer between the two upper electrodes and the substrate. The lower module has a base, a lower touch layer, a bottom insulation layer and two lower electrodes. The spacer is mounted between the upper touch layer of the upper module and the lower touch layer of the lower module to space apart the upper touch layer of the upper module and the lower touch layer of the lower module. Based on the above structure, the conductive layers in the resistive touch panel are capable of properly sheltering electrodes to prevent the electrodes from being observed.

Abstract: 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.

Abstract: A capacitive touch panel has a transparent substrate and an ink layer. The transparent substrate has an indium tin oxide (ITO) layer and a lead wire region. The ITO layer is mounted on a bottom surface of the transparent substrate and has multiple electrodes mounted thereon. The lead wire region is formed on a bordering portion of the bottom surface of the transparent substrate and has multiple lead wires mounted thereon and electrically connected to the electrodes. The ink layer is mounted on a top surface of the transparent surface and corresponds to the lead wire region. Accordingly, the lead wires do not aesthetically affect the capacitive touch panel, downstream manufacturers are not required to mount a bonding layer and a protection layer, thereby not only saving the manufacturing process and material cost but also reducing the overall thickness of electronic devices using the capacitive touch panel.

Abstract: A projected capacitive touch panel with impedance adjustment structure has an X-axis sensing layer and a Y-axis sensing layer. The X-axis sensing layer has multiple X-axis electrode strings. Each X-axis electrode string has multiple X-axis electrodes connected in series. The Y-axis sensing layer has multiple Y-axis electrode strings. Each Y-axis electrode string has multiple Y-axis electrodes in series. The Y-axis electrodes and the X-axis electrode are arranged alternately to form a coupling capacitor between an X-axis electrode and a Y-axis electrode. At least one gap is formed on part of or all the X, Y axis electrodes to reduce the electrode area and the impedance of the electrodes, thereby enhancing the sensing sensitivity and being beneficial to enlarge the size of the touch panel.

Abstract: A projected capacitive touch panel having a resistance fine-tuning structure has an X-axis sensing layer and a Y-axis sensing layer. The X-axis sensing layer and the Y-axis sensing layer respectively have multiple X-axis electrode arrays and multiple Y-axis electrode arrays. Each X-axis electrode array or each Y-axis electrode array is composed of multiple electrodes and multiple connection portions. Each connection portion is connected between adjacent two of the electrodes of one of the X-axis or Y-axis electrode arrays. By varying widths and adjusting resistance of the connection portions of the X-axis electrode arrays and the Y-axis electrode arrays, the touch sensitivity of the touch panel can be enhanced and the size of the touch panel can be enlarged.

Abstract: A touch panel having non-integrated and securely attached portions of a substrate has a substrate and an extended portion. The substrate takes a regular form and has two opposite surfaces, multiple edge walls and a transparent electrode layer. The transparent electrode layer is formed on one of the opposite surfaces of the substrate. The extended portion has a thickness matching that of each edge wall and is securely attached to one of the edge walls. Accordingly, a substrate having a specific form can be formed by non-integrated parts without cutting off unnecessary material during a specific cutting process, thereby simplifying the fabrication process and saving the material cost.

Abstract: A projected capacitive touch panel has an X-axis sensing layer and a Y-axis sensing layer. The X-axis sensing layer includes a plurality of sensing rows, each of which has two or more electrode sequences connected in parallel. The Y-axis sensing layer includes a plurality of sensing columns, each of which has two or more electrode sequences connected in parallel. Each electrode sequence has a plurality of Y-axis electrodes connected in series. Each of the Y-axis electrodes interposes or aligns with an X-axis electrode. The projected capacitive touch panel effectively reduces the impedance of each of the sensing columns and sensing rows, thus having higher sensitivity for a controller. The arrangement of the X-axis sensing layer and the Y-axis sensing layer is also useful for enlarging the size of the projected capacitive touch panel.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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 bottom 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.

Abstract: 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.
