Touch panel device

The present invention relates to a touch panel structure, and more particularly to a touch panel structure fabricated on a single substrate.

The touch panel is an increasingly popular human interface device. When the user views the text or graphics in the screen behind the touch panel and touches the corresponding position, the touch panel senses the touch signals and transmits them to the controller. Processing is performed to generate an output signal corresponding to the position, and common sensing methods are resistive, capacitive, infrared, and ultrasonic. For example, the capacitive sensing system uses a capacitive sensor, and when the user touches the touch panel, the capacitance value of the contact position changes. Therefore, when the user touches a different position, the sensing system calculates the degree of change in capacitance and then produces an output signal corresponding to the position.

A common touch panel includes one or more layers of sensing electrodes, a substrate for supporting a sensing electrode, a conductive line, a shielding element, and another substrate that provides functions such as scratch resistance, anti-glare, or anti-reflection, etc. In the touch panel, a part of the components are separately fabricated on the two substrates and then combined. For example, a shielding element and a conductive line are fabricated on one substrate, and a sensing electrode is formed on the other substrate. After the two substrates are combined, the touch signal can be transmitted by connecting the sensing electrode to the conductive line, and the shielding element is utilized. The conductive traces are masked to prevent visual obstructions from being inconsistent with the display elements. However, the manufacturing method using two substrates not only produces a touch panel with a relatively large size, but also, in order to correctly connect the sensing electrodes of the two substrates and the conductive lines, attention must be paid to the positioning when joining the two substrates. And increase the complexity of production.

The touch panel structure of the present invention comprises a single integrated substrate, a sensing electrode, a conductive line and a shielding element. The substrate has a substantially transparent first region and a substantially non-transmissive second region (ie, an adjacent region). The first sensing electrode is configured to detect a touch signal, and the conductive circuit is electrically connected to the substrate. The sensing electrode is disposed on the adjacent region of the substrate, and the sensing electrode, the conductive line and the shielding member are disposed on the substrate.

1 is a top view of a touch panel 100 according to a first embodiment of the present invention. The touch panel 100 includes a substrate 10 , a plurality of sensing electrodes 20 , a plurality of conductive lines 30 , and a shielding member 40 . For the sake of brevity, only the horizontal sensing electrodes 20 and the conductive lines 30 are shown in the figure. In addition, vertical sensing electrodes and corresponding conductive lines may be used, or horizontal and vertical sensing may be used simultaneously. The electrode and the corresponding conductive line.

The purpose of the present invention is to manufacture a touch panel of a single substrate, which has both support and protection functions, and includes a visible area and an adjacent area adjacent to the visible area for various displays. In order to achieve a thinned touch panel design, the sensing electrodes, the conductive lines, the shielding elements and other components are fabricated on a single substrate, and the touch panel of the single substrate can be directly combined with the display. Thus, the thickness and cost of one substrate can be omitted, and the production steps of joining the two substrates can be omitted and more efficient.

The substrate 10 may be a substantially transparent inorganic non-conductive substrate (such as glass) or an organic non-conductive substrate (such as rubber), and may be coated, printed, dyed, plated or pasted on the substrate 10. Prepare components for anti-scratch, anti-glare or anti-reflection functions. In addition, it is also possible to select a substrate having an appropriate hardness according to different product applications, such as a glass having high toughness or an elastic material having flexibility. Since the non-conductive substrate described above has substantially a certain transparency, the substrate 10 has a substantially transparent viewing area 11 for viewing information of the display below it. The area between the viewable area 11 and the edge of the substrate 10 is a substantially non-perspective adjacent area 12, and an element that easily obscures the line of sight can be placed in this area.

The sensing electrode 20 may use Indium Tin Oxide, Aluminum Zinc Oxide, Zinc Tin Oxide, or other substantially transparent conductive materials such as conductive glass and conductive polymer ( Conductive Polymer), carbon nanotubes and other materials. The sensing electrode 20 is disposed on the visible area 11 and the adjacent area 12 and has an appropriate electrode pattern to sense the touch position. The conductive line 30 can be electrically connected to the sensing electrode 20 in the adjacent region 12 of the substrate for transmitting the touch signal to the signal processing device 80. The conductive line 30 can be made of metal materials such as aluminum, silver, copper, etc. The electrode 20 is of the same conductive material.

If the conductive line 30 has a metallic color or other opaque color, the wiring of the conductive circuit 30 may cause a visual unsightiness. Accordingly, a shielding element 40 is disposed on the adjacent region 12 to substantially shield the conductive traces 30 from the background light to reduce the visual impact. The shielding member 40 is not necessarily completely opaque, and may be made of different opacity materials, such as black or other colors of substantially opaque photoresist, resin or ink, etc. Light leakage and an effect of reducing the color difference between the conductive line 30 and the surrounding area. Further, when the substrate 10 is prepared, the shielding member 40 may be previously provided on the substrate 10 by coating, printing, dyeing, plating, or pasting. The components in the present embodiment and the subsequent embodiments may be made of materials as described in the preceding paragraph or other suitable materials according to different application requirements.

The adjacent area 12 in FIG. 1 is located at the four edges of the touch panel. In addition, the adjacent area 12 can also be disposed only at one edge of the substrate 10, or the position and shape of the adjacent area 12 can be adjusted in accordance with the design of the product. For example, in FIG. 22, the visible area 11 of the touch panel 2200 has substantially non-perspective areas 13 and 14, and the substantially non-perspective areas 13 and 14 can set a special function button area corresponding to the mobile phone, such as a telephone call function. And hang up the call function, at this time, the geometrical distribution of the sensing electrode 20 and the conductive line 30 (not shown) can be correspondingly designed, so that the conductive line 30 is only disposed under the substantially non-perspective areas 13 and 14, and can be touched. The control panel 2200 has a larger area of the see-through area 11 and can be used with a display without a bezel design.

In the horizontal direction of the sensing electrode 20 shown in FIG. 1 , if the sensing electrode 20 and the sensing electrode 21 of the horizontal and vertical directions are used at the same time, the sensing electrode 20 and the sensing electrode 21 can be completely replaced by an insulating material. Isolated, it can also be uniquely designed for electrode patterns. A more detailed configuration of the sensing electrode 20 and the sensing electrode 21 is shown in Fig. 23, in which the lower right insulating material 96 and the wire 94 are deliberately removed to show the relative position of the wire 92 to other elements. The sensing electrode 20 may be composed of a plurality of sensing electrode patterns 90 and a wire 94. The sensing electrode 21 is composed of a plurality of sensing electrode patterns 90 and wires 92, and electrically isolates the wires 92 and wires 94 using an insulating material 96. In order to ensure that the sensing electrode 20 and the sensing electrode 21 are not turned on, an erroneous touch signal can be avoided. In the Fig. 23, the A-A' tangent position can be varied. For example, in the cross-sectional view (A), the wire 92 is covered with an insulating material 96, and the wire 94 is electrically connected to the electrode pattern 90 over the insulating material 96. Or in the cross-sectional view (B), the wire 92 and at least a portion of the electrode pattern 90 are covered with an insulating material 96, and the wire 94 is electrically connected to the electrode pattern 90 by the through hole 98 on the insulating material 96. For example, in the cross-sectional view (C), the wire 92 is covered with the insulating material 96, and the electrode pattern 90 and the wire 94 are simultaneously fabricated using the same material, or the electrode pattern 90 is first fabricated and then electrically connected by the wire 94 of the same material.

The electrode pattern of the present invention may also adopt the variation in FIG. 24, for example, the two sensing electrodes 20 on the left side are composed of a plurality of electrode patterns 90 and a plurality of wires 92 of different sizes, or two sensing electrodes as the right side. The electrodes 20 are each composed of only one electrode pattern 90. The embodiment described in FIG. 24 is a capacitive touch panel structure in which the electrode patterns 20 are disposed in the Y direction, and when different positions of the touch electrode patterns 20 are generated, different capacitance value changes are generated, and the touch can be known. The Y coordinate of the control position. Therefore, the electrode pattern 20 can detect touch signals in the X direction and the Y direction. In addition, each of the electrode patterns 90 may have the same size but different conductivity or other manner of address coding, so that the electrode pattern 90 can simultaneously detect the touch signals in the first direction and the second direction. Such an address-coded electrode pattern design can be used in the embodiment of the present invention.

2 is a cross-sectional view of the A-A' tangent position in FIG. 1 . The touch panel structure 200 includes a substrate 10 made of a transparent non-conductive material such as glass or plastic. The substrate 10 is characterized by a single integrated substrate having both support and protection functions, including a visible area and an adjacent area adjacent to the visible area. The sensing electrode 20, such as a transparent conductive material such as indium tin oxide, is located under the substrate 10 for sensing the touch signal. Below the sensing electrode 20 is a shielding element 40 which is substantially opaque and non-conductive. The shielding element 40 has a through hole 50 at a suitable position, so that the conductive line 30 can be electrically connected to the sensing electrode 20 through the through hole 50, Conducting touch signals. The shielding element 40 has shielded most of the conductive lines 30. At this time, the material of the conductive lines 30 and the size of the control openings 50 can be appropriately selected to reduce the visible area of the conductive lines 30. For example, limiting the opening size to the micron (μm) level (eg, less than 30 microns in diameter) can reduce the visual impact. In addition, the sensing electrode 20 can also be electrically connected to the conductive line 30 through the through hole 50.

As shown in the second embodiment of FIG. 3, the touch panel structure 300 includes a substrate 10, a sensing electrode 20, a conductive line 30, a shielding member 40, and a through hole 50. In this embodiment, the conductive line 30 is made of an appropriate size. Between the substrate 10 and the shielding member 40, the visual effect is reduced by appropriately selecting the material of the conductive line 30 and controlling the visible area or position of the conductive line 30. The substrate property is a single integrated substrate having both support and protection, including a visible area and a neighboring area adjacent to the visible area. For example, the size of the conductive traces 30 is limited to the micron scale, or the location of the conductive traces 30 is fabricated in a region that the display bezel can cover. In this embodiment, the sensing electrode 20 can be connected to the conductive line 30 through the through hole 50 to transmit the touch signal, or the conductive line 30 can be connected to the sensing electrode 20 through the through hole 50 to conduct the touch signal.

The shielding element 40 in this embodiment uses a material that is opaque and has an anisotropic conductive, in which case only the anisotropic conductive material at the region 41 is treated, such that between the sensing electrode 20 and the conductive line 30. The shielding element 40 has conductivity in the Y direction, and the X direction of the shielding element 40 has a large resistance value and can be regarded as non-conductive. The two sensing electrodes 20 or the two conductive lines 30 do not pass through the shielding element 40. Turns on and produces an erroneous signal. For example, the general-directional conductive material that can be obtained in the market can have a resistance value of less than 15K ohm in the treated region, and the resistance value of the shielding member 40 between the X direction of the shielding member 40, the sensing electrode 20 or the conductive line 30 can be reached. 10⁸Ohm/30um can be considered as non-conductive. Therefore, in the embodiment, the shielding member 40 does not need to be opened, and the sensing electrode 20 and the conductive line 30 can be electrically connected in an appropriate position, and the effect of shielding the conductive line 30 can be achieved. In addition, the distance between the two conductive lines 30 can be set to be much larger than the distance between the sensing electrode 20 and the conductive line 30, so that the impedance between the conductive line 30 and the sensing electrode 20 is much lower than between the two conductive lines 30. The impedance, therefore, does not cause an erroneous signal between the two conductive traces 30 via the shield element 40.

For example, the size of the conductive traces 30 is limited to the micron scale, or the location of the conductive traces 30 is fabricated in the area covered by the display bezel. In this embodiment, the shielding member 40 uses a material having an isotropic conductivity. At this time, only the anisotropic conductive material at the region 41 is processed, so that the sensing electrode 20 and the conductive line 30 can be shielded by the region 41. The Y direction of 40 is electrically conductive and is turned on. On the other hand, the shielding element 40 has a large resistance value in the X direction and can be regarded as having no conductivity, and the two sensing electrodes 20 or the two conductive lines 30 are not turned on via the shielding member 40 to generate an erroneous signal. In addition, the distance between the two conductive lines 30 can be set to be much larger than the distance between the sensing electrode 20 and the conductive line 30, so that the impedance between the conductive line 30 and the sensing electrode 20 is much lower than between the two conductive lines 30.
