First embodiment

Referring to fig. 1 to fig. 6, a flowchart of a dual mode touch method, a structural schematic diagram of a dual mode touch device, a usage state schematic diagram of a first operation of the dual mode touch device, a first usage state schematic diagram of a second operation of the dual mode touch device, a second usage state schematic diagram of the second operation of the dual mode touch device, and a functional block diagram of the dual mode touch device according to a first embodiment of the present invention are respectively shown. As shown in the drawings, a dual-mode touch method according to a first embodiment of the present invention at least includes the following steps:

first, as shown in fig. 1 to 6, a first signal is sent towards the first detection area S1 or the second detection area S2 by the stylus module 3 (i.e. step S100). For example, referring to fig. 1 to 6, the dual-mode touch device Z provided by the present invention includes a host module 1, and the host module 1 may be a general notebook computer. The host module 1 may include a first body unit 10, a second body unit 11, a first touch unit 12, a first processing unit 13, a second touch unit 14, a second processing unit 15, and a control module 16. Further, the first body unit 10 may be an upper cover structure, and the second body unit 11 may be a lower base structure, but not limited thereto. The first body unit 10 may have a display element 100 thereon, and the display element 100 has a first detection region S1; the display element 100 may be a display. The first processing unit 13 is electrically connected to the display device 100, and the first processing unit 13 may be disposed in the first body unit 10 or the second body unit 11; the first processing unit 13 may be a circuit board or a processor with processing and control functions, but not limited thereto. The second body unit 11 can be movably connected to the first body unit 10, the second body unit 11 can have a touch and press element 110 thereon, and the touch and press element 110 has a second detection area S2; the touch device 110 may be a touch pad. The second processing unit 15 is electrically connected to the touch element 110, and the second processing unit 15 may be disposed on the first body unit 10 or the second body unit 11; the second processing unit 15 may be a circuit board or a processor with processing and control functions, but not limited thereto.

Further, as shown in fig. 1 and 5, the touch device Z with dual modes of the present invention can be used with the stylus module 3, or the touch device Z with dual modes of the present invention can further include the stylus module 3. The stylus module 3 may be a general active capacitive stylus, but not limited thereto, and the dual-mode touch device Z of the present invention may also be used in combination with other types of capacitive stylus. The stylus module 2 may include a pen body unit 30, a transceiver unit 31, and a third processing unit 32. The pen body unit 30 may have a contact portion 300; the pen body unit 30 may be a body structure of a touch pen, the contact portion 300 may be a pen point (or writing end) of the touch pen, and the contact portion 300 may be made of a conductive material. The transceiver unit 31 is electrically connected to the contact 300; the transceiver unit 31 may be a signal transmitting module with receiving and transmitting functions, but is not limited thereto. The third processing unit 32 is electrically connected to the transceiver unit 31, and the third processing unit 32 may be a circuit board with processing and control functions, but not limited thereto. The stylus module 3 may further include a battery (not shown) capable of being repeatedly charged and discharged.

Therefore, as shown in fig. 3 and 4, when the user approaches or contacts the contact portion 300 of the stylus module 3 to the display device 100, or approaches or contacts the contact portion 300 of the stylus module 3 to the touch device 110, the third processing unit 32 may control the transceiver 31 to send the first signal toward the first detection area S1 or the second detection area S2.

Next, the first sensing elements 120 located in the first sensing region S1 are passed to receive the first signals and generate a first signal group (i.e., step S102). For example, as shown in fig. 1 to 3 and 6, the first touch unit 12 is disposed on the first body unit 10, electrically connected to the first processing unit 13, and includes a plurality of first sensing elements 120 disposed in the first detection area S1. The first touch unit 13 is preferably disposed together with the display device 100, the plurality of first sensing elements 120 are disposed in the display device 100, and the display device 100 corresponds to the first detection area S1 (i.e. the first detection area S1 may be equal to the display area of the display device 100); that is, the first touch unit 13 and the display device 100 form a touch display. Therefore, when the transceiver unit 31 of the stylus module 3 faces the first detection area S1, a part of the first sensing elements 130 in the plurality of first sensing elements 130 receive the first signal and generate a first signal group.

Next, in response to the generated first signal group, the first processing unit 13 is configured to calculate and obtain first coordinates from the first signal group (i.e., step S104). For example, as shown in fig. 1 to fig. 3 and fig. 6, the first processing unit 13 may receive a first signal group outputted by the plurality of first sensing elements 130 and generate a first coordinate correspondingly; the first coordinate may be information of an absolute coordinate.

Next, the control module 16 is configured to control a cursor C displayed by the display element 100 according to the first coordinate (i.e., step S106). For example, as shown in fig. 1 to 3 and 6, the control module 16 may be electrically connected to the first processing unit 13 and the second processing unit 15; the control module 16 may be a circuit board or a central processing unit with processing and control functions, but not limited thereto. After receiving the first coordinate transmitted by the first processing unit 13, the control module 16 may drive the cursor C displayed on the display element 100 to move to a position where the contact portion 300 approaches or touches the display element 100 according to information included in the first coordinate.

In addition, after the above step S100, the first signal is received and the second signal group is generated by the plurality of second sensing elements 140 located in the second detection region S2 (i.e., step S108). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, the second touch unit 14 is disposed on the second body unit 11, electrically connected to the second processing unit 15, and includes a plurality of second sensing elements 140 disposed in the second detection area S2. Wherein a plurality of second sensing elements 140 are preferably disposed with the touchdown element 110; that is, a plurality of second sensing elements 140 may be disposed in the touch element 110, and the touch element 110 corresponds to the second sensing region S2 (i.e., the second sensing region S2 may be equal to the touch area of the touch element 110). Therefore, when the transceiver unit 31 of the stylus module 3 faces the second detection area S2, some of the second sensing elements 140 of the plurality of second sensing elements 140 receive the first signal and generate a second signal group.

Next, in response to the generated second signal group, the second processing unit 15 is configured to calculate and obtain second coordinates from the second signal group (i.e., step S110). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, the second processing unit 15 can receive the second signal group outputted by the plurality of second sensing elements 140 and generate a second coordinate correspondingly; wherein the second coordinate may be information of an absolute coordinate.

Then, after the first time, a second signal is sent to the second detection area S2 by the stylus module 3 (i.e. step S112). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, the third processing unit 32 can control the transceiver unit 31 to continuously send out the signal. Therefore, when the stylus module 3 continuously approaches or contacts the touch-pressure element 110, the third processing unit 32 can control the transceiver 31 to send the second signal toward the second detection area S2. Wherein a first time may be spaced between a point in time when the second sensing element 140 receives the second signal and a point in time when the first signal is received; the first time may be several milliseconds, but is not limited thereto.

Next, a plurality of second sensing elements 140 located in the second detection region S2 are passed to receive the second signals and generate a third signal group (i.e., step S114). For example, referring to fig. 1, fig. 2, and fig. 4 to fig. 6, a part of the second sensing elements 140 in the plurality of second sensing elements 140 in the second detection region S2 may receive the second signal transmitted by the transceiver unit 31, and generate a third signal group.

Next, in response to the generated third signal group, the second processing unit 15 is configured to calculate and obtain third coordinates from the third signal group (i.e., step S116). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, the second processing unit 15 receives the third signal group output by the plurality of second sensing elements 140 and correspondingly generates a third coordinate; wherein the third coordinate may be information of an absolute coordinate.

Next, the second processing unit 15 is configured to calculate the first displacement information according to the second coordinate and the third coordinate (i.e., step S118). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, after the second processing unit 15 generates the third coordinate, it can calculate a difference between the third coordinate and the second coordinate, and correspondingly generate the first displacement information. The first displacement information may include a displacement amount in a first axial direction and a displacement amount in a second axial direction, where the first axial direction may be an X axis, and the second axial direction may be a Y axis, but is not limited thereto.

Finally, the configuration control module 16 controls the cursor C displayed by the display element 100 according to the first displacement information (i.e., step S120). For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, after receiving the first displacement information transmitted by the second processing unit 15, the control module 16 may drive the cursor C displayed by the display element 100 to stay or move according to the displacement related information included in the first displacement information.

Further, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, when the stylus module 3 continuously approaches or contacts the touch-pressure element 110, and the third processing unit 32 controls the transceiver unit 31 to emit a plurality of signals toward the second detection region S2, the plurality of second sensing elements 140 in the second detection region S2 can receive the plurality of signals and correspondingly generate a plurality of signal groups. Then, the second processing unit 15 may sequentially receive the plurality of signal groups and sequentially generate a plurality of coordinates. Next, the second processing unit 15 can calculate a plurality of displacement information according to the plurality of coordinates, and output the displacement information to the control module 16, so that the control module 16 drives the cursor C displayed by the display element 100 to displace (as shown in fig. 5).

In addition, when the first time is less than or equal to the preset time, the second processing unit 15 calculates first displacement information according to the second coordinate and the third coordinate; when the first time is greater than the preset time, the second processing unit 15 does not calculate the first displacement information. For example, as shown in fig. 1, fig. 2, and fig. 4 to fig. 6, when the stylus module 3 continuously approaches or contacts the touch pressure element 110, a first time interval between a time point when the second sensing element 140 receives the second signal and a time point when the first sensing element receives the first signal matches or is within a predetermined time (for example, several milliseconds, but not limited thereto). When the stylus module 3 moves away from the touch-pressure element 110 and then approaches or contacts the touch-pressure element 110 again (i.e. the user takes the stylus module 3 away and approaches or contacts the stylus module 3 to the touch-pressure element 110 again), the first time interval between the time point when the second sensing element 140 receives the second signal and the time point when the first signal is received is greater than the preset time; at this time, the second processing unit 15 does not calculate the first displacement information, i.e., the second processing unit 15 does not calculate the difference between the third coordinates and the second coordinates.

In another embodiment, at least one first sensing element 120 of a part of the first sensing elements 120 located in the first detection region S1 sends a first sensing signal towards the stylus module 3, and at least one first sensing element 120 of another part of the first sensing elements 120 receives the first signal; alternatively, at least one second sensing element 140 of a part of the second sensing elements 140 located in the second detection region S2 sends a second sensing signal towards the stylus module 3, and at least one second sensing element 140 of another part of the second sensing elements 140 receives the first signal. For example, referring to fig. 1 to 6, the first touch unit 12 and the first processing unit 13 of the present invention may also be configured such that the first processing unit 13 provides the first sensing signal to a part of the first sensing elements 120. Then, when the stylus module 3 approaches the display device 100, the stylus module 3 may receive the first sensing signal through the contact portion 300 and transmit the first sensing signal to the third processing unit 32 through the transceiver unit 31; next, the third processing unit 32 can control the transceiver unit 31 to send out the first signal toward the first detection region S1 for being received by another part of the first sensing elements 120. In contrast, the second touch unit 14 and the second processing unit 15 of the present invention can also be configured to operate as described above.

According to the above, the first embodiment of the present invention further provides a dual-mode touch device Z, which includes a host module 1. The host module 1 includes a first body unit 10, a second body unit 11, a first touch unit 12, a first processing unit 13, a second touch unit 14, a second processing unit 15, and a control module 16.

The first touch unit 12 is disposed on the first body unit 10, and the first touch unit 12 includes a plurality of first sensing elements 120 disposed in the first detection area S1, wherein the plurality of first sensing elements 120 are configured to receive a first signal and generate a first signal group.

The control module 16 is electrically connected to the first processing unit 13 and the second processing unit 15. Wherein after the first time has elapsed, the plurality of second sensing elements 140 located in the second detection region S2 receive the second signal and generate a third signal group; wherein, the second processing unit 15 is configured to calculate and obtain a third coordinate according to the second signal set, and the second processing unit 15 calculates the first displacement information according to the second coordinate and the third coordinate. The control module 16 controls a cursor C displayed by the display element 110 according to the first coordinate or the first displacement information.

Further, the dual mode touch device Z of the present invention further includes a stylus module 3, which includes a pen body unit 30, a transceiver unit 31 and a third processing unit 32.

Second embodiment

Fig. 7 and fig. 8 are a flowchart of a dual-mode touch method and a usage status diagram of a dual-mode touch device according to a second embodiment of the invention, and refer to fig. 1 to fig. 6 together. As shown in the figure, the dual-mode touch method provided by the present invention may further include the following steps:

first, the second detection region S2 is touched by an object B (i.e., step S200). For example, as shown in fig. 7 and 8, the user can directly contact any part of the body (in the embodiment, a finger is taken as an example, but not limited thereto) with the touch-press element 110 to operate the cursor C.

Next, the electrical property change in the second sensing region S2 is detected by the plurality of second sensing elements 140 located in the second sensing region S2, and a fourth signal group is generated (i.e., step S202). For example, as shown in fig. 7 and 8, when the user' S fingers contact the touch element 110, the second sensing elements 140 can detect the electrical property change in the second detection area S2 and generate a fourth signal set.

Next, as shown in fig. 7 and 8, in response to generating the fourth signal group, the second processing unit 15 is configured to calculate and obtain a fourth coordinate according to the fourth signal group (i.e., step S204). Wherein, the fourth coordinate may be information of an absolute coordinate.

Then, after a second time, the second detection area S2 is touched by the object B (i.e., step S206). For example, referring to fig. 7 and 8, when the user' S finger continuously touches the touch-pressure element 110, the second sensing element 140 can detect the electrical property change in the second detection region S2 and generate a fifth signal set; a second time may be separated between the time point when the second sensing element 140 detects the first electrical change and the time point when the second electrical change is detected in the second detection region S2; the second time may be several milliseconds, but is not limited thereto.

Next, as shown in fig. 7 and 8, the plurality of second sensing elements 140 located in the second sensing region S2 detect the electrical variation in the second sensing region S2, and generate a fifth signal group (i.e., step S208).

Next, as shown in fig. 7 and 8, in response to generating the fifth signal group, the second processing unit 15 is configured to calculate and obtain a fifth coordinate according to the fifth signal group (i.e., step S210). Wherein the fifth coordinate may be information of an absolute coordinate.

Next, the second processing unit 15 is configured to calculate the second displacement information according to the fourth coordinate and the fifth coordinate (i.e., step S212). For example, referring to fig. 7 and 8, after the second processing unit 15 generates the fifth coordinate, it can calculate a difference between the fifth coordinate and the fourth coordinate, and correspondingly generate the second displacement information. The second displacement information may include a displacement amount in a first axial direction and a displacement amount in a second axial direction, where the first axial direction may be an X axis, and the second axial direction may be a Y axis, but not limited thereto.

Finally, the configuration control module 16 controls the cursor C displayed by the display element according to the second displacement information (i.e., step S214). For example, as shown in fig. 7 and 8, after receiving the second displacement information transmitted by the second processing unit 15, the control module 16 may drive the cursor C displayed by the display element 100 to stay or move according to the displacement related information included in the second displacement information.

It should be noted that, in the above embodiments, the second touch unit 14 of the dual-mode touch device Z of the invention can be controlled by the second processing unit 15 or the control module 16 to be alternately switched to the first mode or the second mode. For example, the second processing unit 15 or the control module 16 may drive the second touch unit 14 to switch from the first mode to the second mode, and then drive the second touch unit 14 to switch from the second mode to the first mode. The second touch unit 14 can be maintained in each mode for several milliseconds, but not limited thereto. Correspondingly, the first touch unit 12 can also be controlled by the first processing unit 13 or the control module 16 to be alternately switched to the first mode or the second mode, which is not specifically described herein.

Further, when the second touch unit 14 is in the first mode, the plurality of second sensing elements 140 can be used for receiving the signal emitted by the stylus module 3. When the second touch unit 14 is switched from the first mode to the second mode, a part of the second sensing elements 140 in the plurality of second sensing elements 140 can emit signals, and the other part of the second sensing elements 140 can be used for receiving signals.

Therefore, in the process of the flow of fig. 7 (i.e., steps S200 to S214), when the second touch unit 14 is switched to the first mode and a part of the second sensing elements 140 receive the signal sent by the stylus module 3, the second processing unit 15 or the control module 16 immediately stops continuing the flow of fig. 7, and then switches to the flow of fig. 1 (for example, the second processing unit 15 or the control module 16 may determine that the signal received by the stylus module 3 by the second sensing elements 140 is step S100 and continue the flow after step S100).

In addition, the first touch unit 12 of the dual-mode touch device Z of the present invention can also be used for detecting the touch of the living being, and the process is similar to the process from step S100 to step S106. In addition, in the process of operating the dual-mode touch device Z by touching the display element 100 with a finger of the user, when the first touch unit 12 is switched to the first mode and a part of the first sensing elements 120 receive a signal sent by the stylus module 3, the first processing unit 13 or the control module 16 also performs a similar manner as described above, i.e., immediately stops performing the biological touch operation process and switches to performing the stylus touch operation process.

However, the above embodiments are only examples of one possible embodiment and are not intended to limit the present invention.
