Description

  The present invention refers to a composite type touch sensor, in particular, one having a capacitor-inductive and resistance-inductive touchpad touch sensor, an interface, and a device for receiving touch sensor signals at the same time.

  In recent years, production technologies related to touch sensors have dramatically improved, and the functions of the products and the quality of the component parts have been constantly improved, and the price has been greatly reduced. Therefore, each type of touch sensor is already widely used on various electronic products. Generally, touch sensors can be roughly divided into three types, such as a capacitor-inductive touchpad, a resistance-inductive touchpad, and an electromagnetic touchpad. For this reason, the features and advantages and disadvantages of each function of these touchpads are somewhat different from those currently developed and applied. For example, resistive inductive touchpads are often used on the displays of small electronic products such as PDAs, electronic lexicons, mobile phones, MP3 digital players, or GPS. And most of capacitor induction type touchpads are applied to mouse pads, virtual, keys, etc. of notebook computers.

  In further discussion, the outline of the structure of a known capacitor-inductive touchpad includes an X-axis inducing layer (X trace) and a Y-axis inducing layer (Y trace). It is installed in the touchpad body, and the X and Y axis induction layers are grounded and connected to the control circuit. When driving, touching the surface of the touchpad with a finger or conductor and sliding it lightly, the capacitor effect occurs at the moment the user's finger or conductor touches, so the control circuit changes the capacitance value, The position touched by the finger or conductor can be determined. The capacitor-inductive touchpad can be input with a finger and has the convenience of an input operation. The input operation does not need to apply pressure, and does not have the disadvantage of causing repeated stress or deformation on the panel to cause damage. And the structure which comprises this kind of touchpad is simple, there are few parts, the yield rate of a product is high, and it is suitable for mass production and cost reduction. In addition, this type of touchpad also has a multi-point guidance function, which means that this type of touch sensor has multiple control functions. Therefore, it can be used for high-level control operations. For example, it can be applied to the operation of a computer game, and the operation of the controlled virtual subject can be made more agile, and more various expression performances can be provided. However, this type of capacitor-inductive touchpad also has a number of drawbacks and awaits improvement. For example, a capacitor-inductive touchpad is susceptible to noise due to EMI interference, causing input signals to be misjudged and malfunctioned. A capacitor-inductive touchpad can be input with a finger and is very convenient. However, the accuracy of the finger input sensor is not high, and it easily causes an erroneous operation and causes a problem in use. In particular, the use of character recognition in the input direction has a relatively large number of strokes such as Chinese characters. Characters with complicated shapes have a very low recognition rate, and it is difficult to reach a practical level. The above problem can be overcome by using a special touch pen, but there are still limitations to use on a relatively small area panel and to input points with relatively high accuracy. In addition, the use of the dedicated touch pen often causes the user to feel very inconvenient when the pen is forgotten or lost.

In the structure of the resistance induction type touchpad, mainly two sheet-like transparent conductive films are included, and they are arranged facing each other with a certain gap. The upper conductive film is placed on one surface of the flexible transparent thin film, the lower conductive film is placed on one surface of a transparent glass substrate made of a hard material, and the two conductive films are sealed in one plate body.
The upper and lower conductive films and plate bodies of this type of resistance-induction touchpad are all transparent materials and are therefore suitable for placement in front of electronic product display displays. The user performs an input function by lightly touching a necessary portion of the panel according to an instruction on the screen. In general, an accurate touch position operation is performed with a pen tip or the like obtained as needed. Therefore, it can be applied to point input with a relatively small use area or relatively high accuracy, and is particularly suitable for character recognition input operations with a relatively large number of strokes and complicated shapes. However, the panel input operation method by the touch of the resistance induction type touch pad gives repeated stress and strain to the conductive film inside the plate body, causing damage. Therefore, when using a tool with a limited service life and a relatively thick finger or tip, you will usually get relatively inaccurate input results, so there are also many input tools that can be used. There is a limit.

Convenient to.

  1 and 2 show a preferred embodiment of the present invention. It includes a capacitor inductive touchpad unit 1, a resistance inductive touchpad unit 2, and a signal processing unit 3. Among them, the capacitor induction touch pad unit 1 includes a panel 11, an X-axis induction layer 12, a Y-axis induction layer 13, an insulating layer 14 installed between the X-axis and Y-axis induction layers, a bottom plate 15, and a first signal output. A wiring 16 is provided. The panel 11 is a flexible high light-transmitting insulating thin film. For example, polyethylene or terephthalate (PET) can be selected as a thin film material. The upper surface of the panel 11 has a hard coat layer (hard coat), and is formed by applying, for example, a high-hardness UV curable paint. This enhances the performance against scratches and contamination of the work surface. As the X-axis induction layer 12 and the Y-axis induction layer 13, a transparent thin film having good conductive characteristics, for example, an indium tin oxide (abbreviated as ITO) thin film can be selected. For the insulating layer 14 between the X-axis and Y-axis induction layers, a light-transmitting insulating material, for example, ink or a highly transparent PET thin film can be selected. A flexible printed circuit board (FPC) can be selected for the first signal output wiring 16, and a slight conduction path is provided on the wiring. And the material of each said plate layer is mutually piled up and bonded together, and it is set as a transparent plate body. The X-axis induction layer 12 and the Y-axis induction layer 13 are provided with contacts 121 and 131, respectively, and are connected to the panel through a silver conduction path 161 provided at the end of the bottom plate. The sensor signals on these conductive films are transmitted to the first signal output wiring 16, and then transmitted to the subsequent signal processing unit 3.

  The resistance induction touch pad unit 2 is mainly configured with a top plate 21, an upper conductive film 22, a lower conductive film 23, a substrate 24, and a second signal output wiring 26. In this embodiment, the top plate 21 and the bottom plate 15 of the capacitor induction type touch pad unit share the same plate material. However, in exceptional circumstances, the top plate 21 and the bottom plate 15 are independently selected, and the same plate material is not shared (an example is shown in FIG. 3). Further, when the capacitor induction type touch pad unit 1 and the resistance induction type touch pad unit 2 are combined to form one plate body, the top plate 21 and the bottom plate 15 are bonded together. The substrate 24 uses a rigid transparent material such as a transparent glass plate, an acrylic plate, or a PET plate. As the second signal output wiring 26, a flexible and printed circuit board can be selected, and a slight conduction path is provided on the wiring. The upper conductive film 22 is provided with a transparent thin film of indium tin oxide having electronic contacts, and is set on the bottom surface of the top plate 21. The lower conductive film 23 is also provided with a transparent thin film of indium tin oxide having electronic contacts, and is placed on the upper surface of the substrate 24. In addition, in the middle of the upper and lower conductive films 22 and 23, the spacers 242 are spaced apart from each other by a large number of spacers 242 and face each other. Further, an insulating adhesive layer is provided around the area where the two conductive films 22 and 23 are arranged, and they are bonded together to form one transparent plate body. Further, the sensor signals on these conductive films are transmitted to the second signal output wiring 26 through the silver conductive path 244 set installed at the panel end, and then transmitted to the subsequent signal processing unit 3. Further, as described in the above structure, since the thickness of the capacitor induction type touch pad unit 1 is very thin, even if the capacitor induction type touch pad unit 2 is mounted on the resistance induction type touch pad unit 2, Does not reduce touch pressure sensitivity. However, the stress impact received by the indium tin oxide thin film material of the upper conductive film 22 is relieved, stress fracture due to a sharp tip can be avoided, and the service life is extended.

  The signal processing unit 3 has a signal discrimination circuit, discriminates the type of touch sensor signal transmitted by the capacitor induction touch pad unit 1 and / or the resistance induction touch pad unit 2, and determines an appropriate signal. A processing mode can be automatically selected, thereby performing a signal processing step. For example, when a user performs an input operation with the composite touchpad of the present invention with a finger, the capacitance sensor signal is applied to the X-axis induction layer 12 and the Y-axis induction layer 13 of the capacitor induction touchpad unit 1 with the touch of the finger. Happens. Since the finger has not yet applied pressure to the panel surface, no signal is generated in the resistance induction touch pad unit 2. As a result, when the capacitor sensor signal of the capacitor induction touch pad unit 1 passes through the first signal output wiring 16 and is transmitted to the signal processing unit 3, the signal determination circuit of the signal processing unit 3 is based on this. And automatically select the capacitor induction type signal processing mode operation. Under the operation mode, the signal processing unit 3 receives and processes only the sensor signal of the capacitor inductive touchpad unit 1 and rejects and does not accept the sensor signal of the resistance inductive touchpad unit 2. In addition, under the operation of the capacitor induction type signal processing mode, the signal processing unit 3 cross-connects the upper conductive film 22 and / or the lower conductive film 23 of the resistance induction type touch pad unit 2 so that the capacitor induction This is a grounding layer for the X-axis guiding layer 12 and the Y-axis guiding layer 13 of the touchpad unit. Thereby, interference and destruction of static electricity or EMI can be prevented. Especially when the combined touchpad of the present invention is used in front of a display, the static electricity remaining on the panel causes electromagnetic interference due to the repeated action of photoelectric signals (radiation) of the display during the period of use. The normal operation of the capacitor induction type touch pad unit can be maintained.

  In addition, for example, when the user performs an input operation on the composite touchpad of the present invention with the pen tip, the pen tip touches the work area of the panel 11, and the upper capacitor induction touchpad unit 1 is very thin, In addition, since it is composed of a flexible material, the pen pressure stress of the pen tip can very easily pass through the plate material of the capacitor induction type touch pad unit 1 and act on the resistance induction type touch pad unit 2. . Sensor signals are also generated when the pen tip pressure stress electrically connects and conducts the conductive films 22, 23 above and below the position of action. Further, even if the pen tip slides on the panel surface and touches it, the capacitor sensor signal is not triggered even if it is touched, so the capacitor inductive touchpad unit 1 does not generate any signal. As a result, when the sensor signal of the resistance induction type touch pad unit 2 passes through the second signal output wiring 26 and is transmitted to the signal processing unit 3, the signal discrimination circuit of the signal processing unit 3 automatically performs Judgment is made and resistance induction type signal processing mode operation is selected. Under the operation mode, the signal processing unit 3 receives and processes only the sensor signal of the resistance induction touch pad unit 2 and rejects and does not accept the sensor signal coming from the capacitor induction touch pad unit 1.

  Furthermore, for example, when the same input operation action of the user causes two types of sensor signals, for example, when using an input tool of a pen-shaped conductor, the conductor causes a capacitor sensor signal in this capacitor inductive touchpad unit 1, Then, the pen pressure causes a sensor signal to the resistance induction type touch pad unit 2. As a result, two types of sensor signals are transmitted to the signal processing unit 3 at the same time, and the automatic judgment principle of the signal discrimination circuit of the signal processing unit 3 is the sensor signal processing of the continuity signal principle during continuous touch sensor operation. The mode operation is automatically selected, and the interruption or change of the sensor signal processing mode that was being operated first is not selected. Further, in a non-continuous or new touch sensor operation, the preferential priority sensor signal processing mode is automatically selected and operated, for example, preferential priority is given to the capacitor sensor signal. Then, after selecting one operation mode, the signal processing operation method is the same as the description of each step above.

  In addition, under certain special needs, the signal determination circuit of the signal processing unit 3 can be replaced with a manually operated signal changeover switch, and the user can operate the signal changeover switch by himself / herself. This is convenient for selecting and determining the processing mode. When capacitor induction type signal processing mode operation is selected with the signal changeover switch, the signal processing unit 3 receives and processes only the sensor signal of the capacitor induction type touch pad unit 1, and the resistance induction type touch pad unit 2 Reject the sensor signal and do not accept it. In the same principle, when the resistance-inductive signal processing mode operation is selected by the signal changeover switch, the signal processing unit 3 receives and processes only the sensor signal of the resistance-inductive touchpad unit 2, and the capacitor-inductive touchpad. Reject the sensor signal coming from unit 1 and do not accept it.
