Detailed ways

The electronic device of this embodiment judges whether to generate a click signal according to the change of pressure received on the touch panel. When the touch pressure increases, the sensing area of the finger pressed to the touch panel will increase, so the sensing value of the capacitance will also increase. Change, thus according to the finger pressure as the control of the input command, that is, when the touch pressure increases from a first pressure value to a second pressure value, it is judged whether the proportion of the sensing area (or capacitance change) increased by the touch pressure is Greater than the reference value, to identify whether the touch action is a valid click action, and send a click signal, which is used to replace the press signal generated by the traditional use of mechanical buttons, and to separate simple pointer movement or dragging actions.

In this embodiment, it is used for a notebook computer as an example, but generally electronic devices with the function of a touchpad are related changes. Among them, the touch panel has the functions of displaying and sensing the cursor position of the electronic device, executing instructions or displaying menus, etc., and when it is touched by humans, it is sent to a control processor inside the notebook computer for judgment, and then controlled by the control processor Convert it into related corresponding instructions to carry out related operations.

FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the present invention. Please refer to FIG. 1 , the electronic device 100 includes a touch panel 110 and a control processor 120 . Wherein the control processor 120 is electrically connected to the touch panel 110 . The voltage or current change generated by the touch action on the touch panel 110 is then transmitted from the touch panel 110 to the control processor 120, and the control processor 120 then uses the internally stored reference value Or refer to the set value such as time, further judge these voltage or current changes to confirm the command generated by the user under the touch action, and finally control the processor 120 to send the relevant control signal to the electronic device to execute or display the user's command. Instructions given below, wherein the control processor 120 can be a central processing unit and related storage components inside a notebook computer or a single chip composed of a microprocessor and related storage components.

In this example, the touch panel 110 has a first touch area 112 and a second touch area 114 . In this embodiment, the first touch area 112 includes a first rectangle 112a and a second rectangle 112b, and the second touch area 114 is a third rectangle 114a disposed on one side of the first rectangle 112a. However, in other embodiments, the first touch area 112 and the second touch area 114 may have other shapes and sizes, which are not limited to the above.

FIG. 2 is a schematic diagram of the impact of touching the touch panel of FIG. 1 and the corresponding internal detection circuit. Please refer to FIG. 2 , when the touch panel 110 receives a touch action, a first pressure value is generated on the touch panel 110, wherein the first pressure value acts on the first area 116a, inside the corresponding touch panel 110 On the detection circuit, for example, in the following figure 2, the energy distribution induced by the capacitance value is taken as an example. Above a standard value V, most of the distribution will be concentrated between a and b. When the user wants to perform a function like moving a mouse, he can use his finger to perform a sliding action on the touchpad 110, because in the case of movement, the user will maintain the first pressure value or a slightly increased or decreased pressure value to perform or already The deviation from the first area 116a is very far, so the control processor 120 continuously sends corresponding control signals according to the movement situation, so as to display the position of the cursor on the display screen of the electronic device 100 .

Conversely, when the user intends to perform a function similar to pressing the left or right button of the mouse on the electronic device 100 of this embodiment, then press the touchpad 110 with the finger on the original first area 116a to generate a second pressure value , since the second pressure value is greater than the first pressure value, the range of influence on the touch panel 110 is expanded from the original first area 116a to a second area 116b, as shown in FIG. 2, which corresponds to the distribution shown in the figure below. Changes occur, for example, most of the distribution above the standard value V is originally concentrated between a and b, and expanded to concentrate between c and d. Therefore, the control processor 120 can make an instruction judgment and send a clear message according to the change in the above distribution. A control signal, such as a confirmation click signal generated.

In addition, because the electrical signals detected on the touch panel 110 will be arranged like contour lines, the electrical signals will be somewhat different between the area touched by the finger and the area not touched, and the pressing size will also affect the difference in the adjacent area touched by the finger. Therefore, the control processor 120 can determine whether the increase ratio of the touch area 116 at the second pressure value P2 is greater than the reference value, so as to identify whether the touch action is a valid click action. When it is confirmed that the touch action is a valid click action, the electronic device can determine that the finger is going to press down, so that the control processor 120 sends a click signal to perform an instruction function like pressing the left mouse button or pressing Display menu function of the right mouse button.

In this embodiment, a reference time can also be set in the control processor 120, that is, in addition to judging whether the increase ratio of the touch area 116 to the second pressure value is greater than the reference value, and increasing the judgment of the second pressure value Whether the duration of the second area 116b is longer than the reference time set in the control processor 120 is to further confirm whether the touch action is a valid click action. Of course, there may also be other ways to identify whether the touch action is a valid click action, and the above is not limited thereto.

In addition, the click signal generated by the touch action on the first touch area 112 is a first signal, and the click signal generated by the touch action on the second touch area 114 is a second signal. The signals each perform a different function. In this embodiment, the first signal is to execute the function of the left mouse button, and the second signal is to execute the function of the right mouse button. Whether the user executes the left button or the right button of the mouse is judged according to the position of the touch action on the touch panel 110 . Therefore, in this embodiment, not only the function of the left mouse button will be executed only when an effective click action is performed on the lower left side of the touch panel 110, but the function of the left mouse button will be executed when this action is performed on the entire first touch area 112. .

First, the user touches the touch panel with a first pressure value to generate a touch action (step 210 ). When the touch action increases from the first pressure value to a second pressure value on the touch panel, if the second pressure value increases greater than the reference value, the control processor considers it a valid click action, and the control processor sends a A click signal (step 220), to perform an action similar to the left or right button of the mouse to confirm the command. On the contrary, if the increase range of the second pressure value is not greater than the reference value, it may be other different instructions, for example, a slight pressure for index movement. In addition, in order to improve the confirmation, in this embodiment, it is further included to further judge whether the duration of the second pressure value on the touch panel is greater than a reference time set in the control processor, so as to strengthen the confirmation of whether the touch action is Valid click action.

In this embodiment, when the touch action is the first pressure value on the touch panel, the control processor is adapted to send a control signal, and the control signal can be used to control the position of the cursor displayed on the display screen. When the touch action expands from the first pressure value to the second pressure value, the control processor starts to determine whether the touch action is a valid click action. In addition, the click signal generated by the touch action on the first touch area is a first signal, the click signal generated by the touch action on the second touch area is a second signal, and the first signal and the second The signals each perform a different function. For example, the first signal is to perform the function of the left button of the mouse, and the second signal is to perform the function of the right mouse button, and the function to be performed is distinguished according to the position of the touch action on the touch panel.

To sum up, the electronic device and the touch control method of the present invention determine whether the touch action is a valid click action and send a click signal by controlling the processor to identify the change and increase of the pressure value on the touch panel and the duration of the stay.
