For example, the five-way key 110 in the figure has four direction keys 1101~1104 and a confirmation key 1105, which can be pressed by the user to adjust the size of various parameters in the graphical user interface and confirm. The touch sensing device, the touch surface 100, the five-way button 110 and the button device 11 constitute an input device, which in this example is a touch and button device, mainly for responding to the user.

The portion 313, the bottom portion 3140 of the elastic dome structure 314, and the grounding wire 3149 can be etched by using a single-sided conductor layer on the single-layer board, thereby saving cost and man-hours. However, since the insulating material key housing 315 covering the outer periphery of the elastic dome structure 314 is pressed, the elastic dome structure 314 completed by the conductor is deformed to change the distance between the elastic dome structure 314 and the central portion 312, so that The capacitance value between the two is also increased as the pitch is reduced, so that the change in the capacitance value can be detected between the ground line 3149 extending outward from the elastic dome structure 314 and the signal line 310 of the sensing electrode 31. The external sensing circuit can determine that the corresponding button is pressed according to the sensed capacitance value being greater than a threshold value.

As a result, after the insulating material button housing 615 covering the outer portion of the elastic dome portion 612 is pressed, the elastic dome portion 612 completed by the conductor is deformed to change the distance between the elastic dome portion 612 and the first common electrode portion 621 and even contact. Together, the capacitance between the two increases or even saturates as the pitch decreases, so that the common electrode 62 composed of the first common electrode portion 621 and the second common electrode portion 622 and the sensing electrode 61 extend out. The change of the capacitance value can be detected between the signal lines 610. Thus, the external sensing circuit can determine that the corresponding button is pressed according to the sensed capacitance value being greater than a threshold value or reaching a saturation state. .

Therefore, the sensing electrode 71 can be connected to an external sensing circuit (not shown) by an independent signal line 710, like the other unshaped electrode shown in FIG. The influence of the user's finger on the capacitance value of the nearby sensing electrode is derived, and the position of the user's finger distribution and the touch gesture represented by the position change are derived.

The common electrode portion 72 is provided at the central hollow portion of the outer ring portion 711, and the common electrode portion 72 and the outer ring portion 711 are not connected to each other. However, the common electrode portion 72 extends through the opening 719 of the outer ring portion 711 to extend the wire 729. Electrically connected to the common electrode portion of other regions, elastic dome The appearance of the portion 712 can be similar to that shown in FIG. 5, and the notch is disposed in alignment with the opening 719. As a result, after the insulating material button housing 715 covering the outer portion of the elastic dome portion 712 is pressed, the elastic dome portion 712 completed by the conductor is deformed to change the distance between the elastic dome portion 712 and the common electrode portion 72 and even contact. Therefore, the capacitance value between the two increases or even saturates as the pitch decreases, so that the change in the capacitance value can be detected between the signal line 710 extending from the common electrode portion 72 and the sensing electrode 71, and thus, The external sensing circuit can determine that the corresponding button is pressed according to the sensed capacitance value being greater than a threshold value or reaching a saturation state. The upper layer 719 can be covered with an insulating layer for protection. The electrode layer 722 disposed on the back surface of the substrate 7 can be used for unnecessary interference on the screen wall.

Referring to FIG. 8A and FIG. 8B , when the five-way key is integrated into the one-dimensional capacitive touch sensing device, the schematic diagram of the sensing unit developed in the present invention can be completed on the circuit board of the single-layer double-sided wire. Preferably, this example is a hybrid application of the first and second embodiments described above, and FIG. 8A is a schematic diagram showing a layout pattern of the wires on the first surface of the circuit board, wherein the second embodiment is as shown in FIG. 6A. The sensor electrodes 61 (shown as the outer ring portion 611) and the first common electrode portion 621 respectively complete the electrodes at both ends of the button, and the first common electrode portion 621 uses the via hole 620 to the second side and the back surface. The common electrode portion 622 (shown in FIG. 8B) completes electrical contact. In addition, FIG. 8A is further provided with a first embodiment as shown in FIG. 3, in which the outer ring portion 311 and the central portion 312 of the sensing electrode 31 are connected via the via holes 3201, 3202 and the connection portion 313 on the back surface. The bottom portion 3140 of the elastic dome structure 314 shown in FIG. 4 is not connected to the outer ring portion 311 and the central portion 312, but the bottom portion 3140 is electrically connected to the second common electrode portion 622 on the back side via the via hole 3203. As can be seen from this example, the position of the button can be placed in the center of the sensing electrode or across the two sensing electrodes as needed without limitation.

A coupling capacitance value is generated between the sensing electrode 81 and the common electrode 82, and the bottom 830 of the elastic button 83 can be completed by a conductive rubber electrically connected to the common electrode 82. Therefore, when the elastic button 83 is pressed, the elastic button is changed. The distance between the bottom of the 83 and the sensing electrode 81 and the common electrode 82 is even in contact with each other, so that the magnitude of the coupling capacitance between the sensing electrode 81 and the common electrode 82 can be changed or even short-circuited, so that the capacitance value between the two is also reduced with the pitch. Increasing or even reaching saturation, so that the change of the capacitance value can be detected between the sensing electrode 81 and the common electrode 82, so that the external sensing circuit can be greater than a threshold value or reach saturation according to the sensed capacitance value. The state is judged that the corresponding button is pressed. The sensing electrodes 81 arranged in a honeycomb manner can also sense the influence of the user's finger on the capacitance value of the nearby sensing electrodes, and then calculate the position of the user's finger and the touch gesture represented by the position change. Furthermore, similar to the concepts of FIGS. 8A and 8B, the fourth embodiment shown in FIGS. 9A and 9B can also support the design of different sensing electrodes, and the hollow region 810 is disposed in the center of the sensing electrode or across the two. Between the sensing electrodes.

In addition, in order to achieve the purpose of waterproofing, the structural surface of the above embodiment may be provided with a waterproof insulating material (as shown in FIG. 9C), but the integration of touch gesture detection and button detection can still be achieved. Taking FIG. 9B as an example, the addition of the waterproof insulating material 90 to the structure of FIG. 9C does not affect the normal function, and the sensing of the touch gesture and the button can operate correctly.

In addition, when the substrate material is unfavorably double-sided processed and made through holes (for example, a ceramic substrate or a curved substrate), the present invention can also be completed by the structure of FIG.

The opening in the insulating varnish 92 is electrically connected to the copper foil layer 91.

Since the sensing electrode of the present invention can achieve the effect of the space sensing, in addition to the touch gesture that can sense the horizontal movement of the user's finger above the button, it can also be used to sense the change of the user's finger at different distances above the button (also It is the position change on the Z axis. Therefore, in this case, the function of a virtual button can be completed on the physical button. For example, by adding the capacitance changes of the plurality of sensing electrodes to sense, the touch sensing can be effectively increased.

The different number of electrode plate combinations will change the effective distance of the space sensing. For example, when the seven sensing electrodes are added together for sensing, the sensing distance will be greater than that of the three sensing electrodes. combination. There are also details of other grouping applications, which have been described in detail in the prior application (US Application Serial No. 13/895,333). By changing the grouping number of the sensing electrodes, the sensing distance of the space sensing can be changed. From another angle, different finger heights will result in different sizes of projected areas, and the larger the projected area covers the sensing electrodes will be generated. The larger the sensing distance. In addition, by setting the sensing distance of the space sensing in different time periods, the scanning action of the Z-axis range can be generated, and the scanning action of the X-axis/Y-axis plane on the original touch sensing device is matched. When the cursor controlled by the user stays in an image moving finger or the palm is close to the panel to perform a similar pressing action, the distance between the finger or the palm and the touch sensing device is gradually increased. Shrinking, as a result, the image in the user interface will change shape according to the action of the pressing, such as bending deformation of the image until the distance is less than a fixed ratio of the Z-axis threshold, for example, 50%, The image (ICON) will produce a broken animation and perform the functions represented by the image.
