Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electrode coupling type according to an embodiment of the present invention.
The capacitive touch screen 1 is a mutual capacitance type capacitive touch screen, and can realize multi-point touch. The array substrate comprises a plurality of first signal electrodes 11 and a plurality of second signal electrodes 12, wherein the extending directions of the first signal electrodes 11 and the second signal electrodes 12 are different, and the first signal electrodes 11 and the second signal electrodes 12 are arranged in a staggered mode. In practical applications, the extending directions of the first signal electrode 11 and the second signal electrode 12 are generally perpendicular to each other, forming a crisscross array. The overlapping position of the first signal electrode 11 and the second signal electrode 12 is a touch point, and the first signal electrode 11 and the second signal electrode 12 are two poles of a mutual capacitance of the touch point.
When a user touches the capacitive touch screen 1, the capacitive coupling between the first signal electrode 11 and the second signal electrode 12 corresponding to a part of the touch points (for example, the touch point a) is affected, so that the capacitance between the first signal electrode 11 and the second signal electrode 12 corresponding to the touch point a is changed. Therefore, when the capacitive touch screen 1 detects the overall mutual capacitance distribution, the mutual capacitance at the touch point a receiving the touch is different from other non-touch positions, so that the capacitive touch screen 1 can detect the specific position (i.e. the touch point coordinate) where the touch point a receiving the touch is located. Even if a plurality of touch points receiving touch exist on the capacitive touch panel 1 at the same time, the specific position of each touch point receiving touch can be detected.
The touch method applied to the capacitive touch screen provided by the invention is explained in detail below.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a touch method applied to a capacitive touch screen according to a first embodiment of the present invention.
It should be noted that the touch method applied to the capacitive touch screen described in this embodiment is not limited to the following steps.
S101: receiving a touch control instruction;
in this embodiment, the touch control instruction is used to describe that a target touch point on the capacitive touch screen is subjected to simulated touch, that is, a simulated human finger touches the target touch point. And acquiring the position information of the target touch point by receiving the touch control instruction, and performing simulated touch on the target touch point.
S102: acquiring an excitation signal of a first signal electrode corresponding to the target touch point, and generating a feedback signal according to the excitation signal;
in this embodiment, the touch control instruction is used to describe the simulated touch on the target touch point on the capacitive touch screen, and carries the position information of the target touch point. The touch method described in this embodiment is to realize the simulated touch on the target touch point. Because the specific position of the target touch point is known, the excitation signal of the first signal electrode corresponding to the target touch point can be collected, and a feedback signal is generated according to the excitation signal; and the target touch point is positioned on the corresponding first signal electrode.
The collection of the excitation signal can be realized by means of electrical coupling. Specifically, the chargeable conductor is capacitively coupled with the first signal electrode, and part of charges are absorbed from mutual capacitances of the first signal electrode and the second signal electrode corresponding to the target touch point, so that the mutual capacitance is reduced, and the absorbed charge flow is an excitation signal for realizing the simulated touch.
S103: feeding back the feedback signal to a second signal electrode corresponding to the target touch point so as to simulate the touch of the target touch point;
in this embodiment, if a simulated touch on a target touch point is to be implemented, it is necessary to cause a mutual capacitance between a first signal electrode and a second signal electrode corresponding to the target touch point to be changed sufficiently, so that the capacitive touch screen can detect that the mutual capacitance corresponding to the target touch point has changed. Feeding the obtained feedback signal back to a second signal electrode corresponding to the target touch point; and the target touch point is positioned on the corresponding second signal electrode. After the second signal electrode receives the feedback signal, the mutual capacitance between the first signal electrode and the second signal electrode corresponding to the target touch point is changed and can be detected by the capacitive touch screen, and the capacitive touch screen judges that the target touch point is touched, so that the target touch point is simulated and touched.
As can be seen from the above, the touch method applied to the capacitive touch screen provided by the invention receives the touch control instruction to perform simulated touch on the target touch point described by the touch control instruction. Specifically, the excitation signal of the first signal electrode corresponding to the target touch point is collected, and a feedback signal is generated according to the excitation signal. And feeding back the feedback signal to a second signal electrode corresponding to the target touch point, and forming simulated touch at the overlapping position (namely the target touch point) of the first signal electrode and the second signal electrode, thereby realizing the simulated touch of the target touch point on the capacitive touch screen.
Referring to fig. 3, fig. 3 is a flowchart illustrating a touch method applied to a capacitive touch screen according to a second embodiment of the present invention.
It should be noted that the touch method applied to the capacitive touch screen described in this embodiment is not limited to the following steps.
S201: receiving a touch control instruction;
in this embodiment, the touch control instruction is used to describe that a target touch point on the capacitive touch screen is subjected to simulated touch, that is, a simulated human finger touches the target touch point. Since the touch method described in this embodiment is directed to the game pad, the touch control instruction may be from a physical key on the game pad, for example, by pressing the physical key on the game pad, the input of the touch control instruction is realized.
Of course, the source of the touch control command is not limited to the physical keys on the game pad, and it may be a preset command signal or a command signal of another control channel, which is not limited herein.
In this embodiment, by receiving the touch control instruction, position information of a target touch point in the touch control instruction is acquired, and is used for performing simulated touch on the target touch point.
S202: acquiring an excitation signal of a first signal electrode corresponding to a target touch point;
in this embodiment, the touch control instruction is used to describe the simulated touch on the target touch point on the capacitive touch screen, and carries the position information of the target touch point. The touch method described in this embodiment is to realize the simulated touch on the target touch point. Because the specific position of the target touch point is known, the excitation signal of the first signal electrode corresponding to the target touch point can be acquired so as to perform the simulation touch operation; and the target touch point is positioned on the corresponding first signal electrode.
The collection of the excitation signal can be realized by means of electrical coupling. Specifically, the touch signal may be electrically coupled (in this embodiment, capacitively coupled) with at least a portion of the first signal electrodes on the capacitive touch screen in advance, the first signal electrode corresponding to the target touch point is selected from the coupled first signal electrodes, and a portion of charges are absorbed from the selected first signal electrode, where the absorbed charge flow is an excitation signal for realizing the simulated touch.
Since the specific position of the target touch point is known, the corresponding first signal electrode and second signal electrode are also known. Therefore, in order to reduce power consumption and simplify the touch process, it is not necessary to collect excitation signals of all coupled first signal electrodes, and instead, before collecting the excitation signals, the first signal electrode corresponding to the target touch point is selected, and the excitation signals are collected from the selected first signal electrode.
Please continue to refer to fig. 1.
It should be noted that the form of capacitive coupling is different from the form of wireless connection or wired connection between the conventional game pad and the capacitive touch screen 1. The capacitive coupling may be in the form that the touch electrode 2 for acquiring/transmitting signals is close to (or in contact with) the first signal electrode 11 to establish a capacitive coupling relationship. Because the capacitive coupling can be formed by approaching or contacting the first signal electrode 11 to transmit the electric signal, the structure of a wire such as a cable is not required to be designed, and the structural form of the equipment can be simplified; and the capacitive coupling does not relate to the transmission process of radio signals, and can greatly reduce the delay of the transmission process of electric signals, so compared with the traditional wireless connection, the wireless communication system has lower response delay.
In addition, in order to provide a touch design adapted to the game pad, the touch design is always connected to the coupled first signal electrode 11 during the period of using the game pad to touch the capacitive touch screen 1, that is, the touch electrode 2 is close to or contacts the first signal electrode 11. The reason for this is that: during the period of using the game pad to touch the capacitive touch screen 1, the user may input touch control commands (for example, by pressing physical keys). If the user inputs a touch control command each time, the touch electrode 2 needs to perform an action of approaching or contacting the first signal electrode 11 to acquire an excitation signal, which may cause response delay at a high level and seriously affect the user experience.
In order to reduce the response delay to the maximum extent, the touch control design provided in this embodiment is to maintain the connection relation with the coupled first signal electrode 11 all the time, and selectively energize the touch control electrode 2 to collect the excitation signal, that is, to energize the touch control electrode 2 while receiving the touch control command. The touch electrode 2 can be capacitively coupled with the first signal electrode 11 in the power-on state to collect the excitation signal, so that the touch electrode 2 does not pass through the charge in the state that the touch electrode 2 does not need to collect the excitation signal.
S203: performing gain processing to generate a feedback signal;
in this embodiment, if a simulated touch on a target touch point is to be implemented, it is necessary to cause a mutual capacitance between a first signal electrode and a second signal electrode corresponding to the target touch point to be changed sufficiently, so that the capacitive touch screen can detect that the mutual capacitance corresponding to the target touch point has changed. Therefore, it is necessary to perform gain processing on the acquired excitation signal, and amplify the amplitude of the excitation signal to a specified amplitude without distortion, so as to cause a sufficient change in the mutual capacitance between the first signal electrode and the second signal electrode corresponding to the target touch point, where the excitation signal after the gain is the feedback signal.
S204: feeding back the feedback signal to a second signal electrode corresponding to the target touch point so as to simulate the touch of the target touch point;
in this embodiment, after the acquired excitation signal is subjected to gain processing, the generated feedback signal needs to be fed back to the second signal electrode corresponding to the target touch point; the target touch point is positioned on the corresponding second signal electrode, and the target touch point is positioned at the overlapping position of the corresponding first information signal electrode and the corresponding second signal electrode. After the second signal electrode corresponding to the target touch point receives the feedback signal, the mutual capacitance between the first information signal electrode and the second signal electrode corresponding to the second signal electrode is obviously changed and can be detected by the capacitive touch screen, so that the target touch point is simulated and touched. It should be noted that only the overlapping position of the first signal electrode providing the stimulation signal and the second signal electrode receiving the feedback signal will form a simulated touch, i.e., a target touch point.
The feedback of the feedback signal can also be realized by means of electrical coupling. Specifically, the touch electrode 2 is close to or in contact with the second signal electrode 12, and is electrically coupled (in this embodiment, capacitively coupled) with at least a portion of the second signal electrode 12 on the capacitive touch screen 1 in advance, and the second signal electrode 12 corresponding to the target touch point is selected from the coupled second signal electrodes 12, and the feedback signal is fed back to the corresponding second signal electrode 12. It also has the effects of low response delay and simplified device structure, which are not described herein again.
During the period of using the game pad to touch the capacitive touch screen 1, the connection relation with the coupled second signal electrode 12 is always kept, namely, the touch electrode 2 is close to or contacts the second signal electrode 12. The touch electrode 2 can be capacitively coupled to the second signal electrode 12 in the power-on state for feeding back the feedback signal, so as to reduce the response delay to the maximum extent.
In the present embodiment, the overlapped positions of the coupled first signal electrodes 11 and the second signal electrodes 12 constitute a simulated touch area 3, where the simulated touch area 3 is a set of touch points that can be simulated by the touch method described in the present embodiment, and the simulated touch area 3 includes the target touch point a. If all the first signal electrodes 11 and the second signal electrodes 12 of the capacitive touch panel 1 are coupled in advance, the simulated touch area 3 is the entire capacitive touch panel 1, and a simulated touch can be performed at any position on the capacitive touch panel 1.
For the game pad, a mapping relationship is usually established between the physical keys arranged on the game pad and part of touch points in the simulated touch area, and pressing the physical keys is mapped to touch points corresponding to the touch physical keys. At present, a virtual key in a plurality of terminal games can be set and adjusted by a player, so that the position of a target touch point in a simulated touch area corresponding to a physical key on a gamepad can be fixed, and a mapping relationship between the physical key and the virtual key in the game is established by dragging the virtual key in the game to the position of the target touch point corresponding to the physical key. Therefore, pressing the physical key triggers the simulation touch of the corresponding target touch point, namely the simulation touch of the game virtual key at the target touch point.
However, it is not excluded that the virtual keys in part of the terminal game do not support the player's self-adjusting function. Therefore, before the simulation of the touch target touch point, that is, before the receiving of the touch control command, it is necessary to establish a communication connection with a touch device (for example, a game pad or the like) including physical keys for outputting the touch control command. The position of the virtual key in the terminal game is the position of the target touch point needing to be simulated. Therefore, a mapping relation between the physical key and a target touch point needing touch simulation needs to be established through the established communication connection; and the target touch point needing to be simulated to touch is in the simulated touch area.
Referring to fig. 4, fig. 4 is a flowchart illustrating a touch method applied to a capacitive touch screen according to a third embodiment of the present invention. It should be noted that the touch method applied to the capacitive touch screen described in this embodiment is different from the touch method applied to the capacitive touch screen described in the above embodiments in that the touch control instruction described in this embodiment is used to describe the simulated touch on the plurality of target touch points.
It should be noted that the touch method applied to the capacitive touch screen described in this embodiment is not limited to the following steps.
S301: and receiving a touch control instruction.
S302: collecting excitation signals of first signal electrodes corresponding to all target touch points, and generating feedback signals according to the excitation signals;
