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 1, 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 the mutual capacitance at 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.
With the resolution of the capacitive touch screen 1 being improved continuously, if a pixel-point-level touch is to be implemented on the capacitive touch screen 1, a corresponding number of touch electrodes for acquiring/transmitting signals need to be set to be coupled with the first signal electrodes 11 of the capacitive touch screen 1 by the second signal electrodes 12. For example, for a capacitive touch screen 1 with a resolution of 1920 × 1080, 1920 × 1080 pixels are located thereon. If analog touch on each pixel point is to be realized, 1920 touch electrodes for collecting excitation signals and 1080 touch electrodes for transmitting feedback signals are required to be arranged.
In order to reduce the number of touch electrodes used for acquiring/transmitting signals, the target touch point B described in this embodiment corresponds to the first signal electrode group 21 and the second signal electrode group 22, and the first signal electrode group 21 and the second signal electrode group 22 are used to describe specific positions (including the target touch point B) of all pixel points in the area defined by the first signal electrode group 21 and the second signal electrode group 22, so as to perform simulated touch. Correspondingly, the touch electrodes 2 are correspondingly disposed on the first signal electrode 11 and the second signal electrode 12 in the first signal electrode group 21 and the second signal electrode group 22 corresponding to the target touch point B, but the touch electrodes 2 do not need to be disposed on the first signal electrode 11 and the second signal electrode 12 corresponding to each pixel point, so that the number of the touch electrodes 2 is reduced, and the touch cost is reduced.
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 contained in a first signal electrode group, and performing gain processing to generate a feedback 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. Since the specific position of the target touch point is known, the excitation signals of the first signal electrodes included in the first signal electrode group corresponding to the target touch point can be collected, and the feedback signals can be generated according to the excitation signals.
If the simulated touch of the target touch point is to be realized, the mutual capacitance corresponding to the target touch point needs to be changed greatly enough and can be detected by the capacitive touch screen. This requires gain processing during the conversion of the excitation signal into a feedback signal to amplify the amplitude of the excitation signal to a specified amplitude without distortion to cause a sufficient change in the amount of mutual capacitance corresponding to the target touch point. The first signal electrode and the second signal electrode of the capacitive touch screen are respectively corresponding to gain components, the size of a target gain used by gain processing is the superposition of the gain components corresponding to the first signal electrode serving as an excitation signal sender and the second signal electrode serving as a receiver, and the excitation signal after gain is a feedback signal.
The collection of the excitation signal can be realized by means of electrical coupling. Specifically, the chargeable conductor (i.e., the touch electrode for collecting/transmitting a signal) is capacitively coupled to the first signal electrode, a part of charges are absorbed from mutual capacitances of the first signal electrode and the second signal electrode corresponding to the target touch point, the mutual capacitance is reduced, and the absorbed charge flow is an excitation signal for realizing the simulated touch.
S103: feeding back a feedback signal to a corresponding second signal electrode in a second signal electrode group so as to simulate a touch target touch point;
in this embodiment, after the excitation signal is converted into the feedback signal, the feedback signal needs to be fed back to the corresponding second signal electrode in the second signal electrode group, so as to realize the simulation of touching the target touch point.
As can be seen from the above, the touch method applied to the capacitive touch screen provided by the present invention receives the touch control instruction to perform the simulated touch on the target touch point described by the touch control instruction. The target touch point corresponds to a first signal electrode group and a second signal electrode group, and the specific positions of the target touch point on the capacitive touch screen are described by using the first signal electrode group and the second signal electrode group corresponding to the target touch point so as to simulate touch on the target touch point, so that the simulated touch on the capacitive touch screen is realized. In addition, the first signal electrode group and the second signal electrode group corresponding to the target touch point are used for simulating touch on the target touch point, touch electrodes used for collecting/transmitting signals do not need to be arranged corresponding to the first signal electrodes and the second signal electrodes, the number of the touch electrodes used for touch capacitive touch screens can be reduced, and touch cost is reduced.
Referring to fig. 1 and 3, fig. 3 is a schematic flow chart of a touch method applied to a capacitive touch screen according to a second embodiment of the present invention.
The excitation signal or the feedback signal may be collected by electrical coupling (in this embodiment, capacitive coupling). Specifically, the touch electrode 2 for acquiring/transmitting signals may be capacitively coupled to the first signal electrode 11 or the second signal electrode 12. Because the touch electrodes 2 are not arranged on the capacitive touch screen 1 one by one in a corresponding manner, but arranged at intervals, a plurality of first signal electrodes 11 or a plurality of second signal electrodes 12 are arranged between the adjacent touch electrodes 2, so that the number of touch electrodes 2 used by the capacitive touch screen 1 can be reduced, and the touch cost is reduced. When the target touch point is located between the first signal electrode 11 or the second signal electrode 12 coupled to the adjacent touch electrode 2, the simulation of the touch target touch point cannot be realized by directly obtaining the excitation signal of the first signal electrode 11 where the target touch point is located and feeding back the feedback signal to the second signal electrode 12 where the target touch point is located.
However, in the case that the touch electrodes 2 are not disposed on the capacitive touch screen 1 one by one corresponding to the first signal electrode 11 and the second signal electrode 12, the target touch point is necessarily located on the signal electrode (including the first signal electrode 11 and the second signal electrode 12) coupled to the touch electrode 2 or located between the signal electrodes coupled to the adjacent touch electrodes 2. When the target touch point is located between the signal electrodes coupled to the adjacent touch electrodes 2, the position of the target touch point between the signal electrodes coupled to the adjacent touch electrodes 2 can be described by adjusting the weight relationship of the gain components corresponding to the signal electrodes coupled to the adjacent touch electrodes 2, and then the specific position of the target touch point on the capacitive touch screen 1 can be described, so as to realize the simulated touch.
The method specifically comprises the following steps: the target touch point is located on the area defined by the first signal electrode 11 in the first signal electrode group corresponding to the target touch point, and the weight relationship of the gain component corresponding to the first signal electrode 11 in the first signal electrode group determines the position of the target touch point on the area defined by the first signal electrode 11 in the first signal electrode group. And the target touch point is located on the area defined by the second signal electrode 12 in the second signal electrode group corresponding to the target touch point, and the weight relationship of the gain component corresponding to the second signal electrode 12 in the second signal electrode group determines the position of the target touch point on the area defined by the second signal electrode 12 in the second signal electrode group, so as to describe the specific position of the target touch point on the capacitive touch screen 1.
The first signal electrode group corresponding to the target touch point may include 1 to 2 first signal electrodes 11. When a target touch point is located on a certain first signal electrode 11 coupled to the touch electrode 2, the first signal electrode group only needs to include the first signal electrode 11, and the position of the target touch point on the area defined by the first signal electrode group can be described; when the target touch point is located between the first signal electrodes 11 coupled to the adjacent touch electrodes 2, the first signal electrode group needs to include 2 first signal electrodes 11 coupled to the adjacent touch electrodes 2, so as to describe the position of the target touch point on the area defined by the first signal electrode group. Similarly, the second signal electrode group corresponding to the target touch point may include 1 to 2 second signal electrodes 12.
In the present embodiment, a first signal electrode group corresponding to a target touch point includes 2 first signal electrodes, and a second signal electrode group corresponding to the target touch point includes 2 second signal electrodes for detailed description. 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. 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. The target touch point corresponds to a first signal electrode group and a second signal electrode group, and is used for describing the specific position of the target touch point on the capacitive touch screen.
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.
S202: collecting excitation signals of all first signal electrodes in a first signal electrode group;
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. Since the specific position of the target touch point is known, the excitation signals of the first signal electrodes included in the first signal electrode group corresponding to the target touch point can be collected for generating the feedback signal.
The collection of the excitation signal can be realized by means of electrical coupling. Specifically, the touch sensing device may be electrically coupled to at least a portion of first signal electrodes on the capacitive touch screen in advance, the first signal electrodes included in the first signal electrode group corresponding to the target touch point are selected from the coupled first signal electrodes, and a portion of charges are absorbed from the selected first signal electrodes, where the absorbed charge flow is an excitation signal for implementing analog 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 the coupled first signal electrodes, and instead, before collecting the excitation signals, the first signal electrodes included in the first signal electrode group corresponding to the target touch point are selected, and the excitation signals are collected from the selected first signal electrodes.
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 a form that the touch electrode 2 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: respectively superposing the gain component corresponding to each first signal electrode in the first signal electrode group and the gain component corresponding to each second signal electrode in the second signal electrode group to obtain a plurality of target gains;
in this embodiment, the first signal electrode group corresponding to the target touch point includes two first signal electrodes, and the target touch point is located on an area defined by the two first signal electrodes, that is, the target touch point is located between the two first signal electrodes. Because the two first signal electrodes included in the first signal electrode group are both corresponding to gain components, the weight relationship of the gain components corresponding to the two first signal electrodes determines the position of a target touch point between the two first signal electrodes, and the specific position of the target touch point is known, the specific position of the target touch point on the area defined by the two first signal electrodes can be described for the capacitive touch screen by adjusting the weight relationship of the gain components corresponding to the two first signal electrodes.
And the second signal electrode group corresponding to the target touch point comprises two second signal electrodes, and the target touch point is located on an area defined by the two second signal electrodes, namely the target touch point is located between the two second signal electrodes. Similarly, the specific position of the target touch point on the area defined by the two second signal electrodes can be described for the capacitive touch screen by adjusting the weight relationship between the gain components corresponding to the two first signal electrodes in the second signal electrode group corresponding to the target touch point.
Please refer to fig. 4. The process of gain processing is described in detail below.
Let two first signal electrodes in the first signal electrode group corresponding to the target touch point C be x1, x2, and two second signal electrodes in the second signal electrode group corresponding to the target touch point C be y1, y 2. The target touch point C is located in an area defined by the first and second signal electrodes x1 and x2 and y1 and y2, i.e., the target touch point C is located in an area surrounded by the first and second signal electrodes x1 and x2 and the second signal electrodes y1 and y 2. The gain component corresponding to the first signal electrode x1 is a, the gain component corresponding to the first signal electrode x2 is b, the gain component corresponding to the second signal electrode y1 is c, and the gain component corresponding to the second signal electrode y2 is d.
The initial excitation signals collected from the first signal electrodes are usually the same in intensity, so the weight relationship (i.e., magnitude relationship) of the gain components a and b corresponding to the first signal electrodes x1 and x2 determines the position of the target touch point C between the first signal electrodes x1 and x 2. For example, the excitation signals of the first signal electrodes x1 and x2 are acquired, and the signal intensity of the excitation signal of the first signal electrode x1 processed by the gain component a is greater than the signal intensity of the excitation signal of the first signal electrode x2 processed by the gain component b, which indicates that the target touch point C is closer to the first signal electrode x1 between the first signal electrodes x1 and x 2.
The magnitude of the target gain used in the gain processing is the superposition of gain components corresponding to a first signal electrode as an excitation signal sender and a second signal electrode as a receiver, and the specific superposition process is as follows:
superposing the gain component a of the first signal electrode x1 with the gain component c of the second signal electrode y1 and the gain component d of the second signal electrode y2 respectively, and performing gain processing on the excitation signal of the first signal electrode x1 by the obtained target gain respectively to obtain a feedback signal corresponding to the second signal electrode y1 and feeding the feedback signal back to the second signal electrode y1 and a feedback signal corresponding to the second signal electrode y2 and feeding the feedback signal back to the second signal electrode y 2;
the gain component b of the first signal electrode x2 is superimposed on the gain component c of the second signal electrode y1 and the gain component d of the second signal electrode y2, and the obtained target gain is used to gain the excitation signal of the first signal electrode x2, so as to obtain the feedback signal corresponding to the second signal electrode y1 and feed back the feedback signal to the second signal electrode y1 and the feedback signal corresponding to the second signal electrode y2 and feed back the feedback signal to the second signal electrode y 2.
It should be noted that the above-mentioned process of adding the gain components may be equivalent to:
the gain component a of the first signal electrode x1 and the gain component b of the first signal electrode x2 are superposed in advance, and then superposed with the gain component c of the second signal electrode y1 and the gain component d of the second signal electrode y2, respectively, and the obtained target gains are subjected to gain processing on any collected excitation signal (usually, the intensities of the collected excitation signals of the first signal electrode x1 and the first signal electrode x2 are equal), so that a feedback signal corresponding to the second signal electrode y1 is obtained and fed back to the second signal electrode y1, and a feedback signal corresponding to the second signal electrode y2 is fed back to the second signal electrode y 2.
As can be seen from the above, the superposition of the signal obtained by gain processing the excitation signal of the first signal electrode x1 by the gain component a and the signal obtained by gain processing the excitation signal of the first signal electrode x2 by the gain component b serves as the input signal of the gain processing corresponding to the second signal electrodes y1 and y 2. Therefore, the weight relationship between the gain components C and d corresponding to the second signal electrodes y1 and y2 determines the position of the target touch point C between the second signal electrodes y1 and y 2. For example, after gain processing, the strength of the feedback signal fed back to the second signal electrode y1 is greater than the strength of the feedback signal fed back to the second signal electrode y2, which indicates that the target touch point C is closer to the second signal electrode y1 between the second signal electrodes y1 and y 2. Since the first signal electrode and the second signal electrode define a plane where the capacitive touch screen is located, after describing the positions of the target touch point C between the first signal electrodes x1 and x2 and between the second signal electrodes y1 and y2, the specific position of the target touch point C on the capacitive touch screen is described for the capacitive touch screen to recognize and detect, thereby realizing the simulated touch on the target touch point C.
It should be noted that the above-mentioned process of adding the gain component is a summation process of the gain components corresponding to the first signal electrode as the sender of the excitation signal and the second signal electrode as the receiver thereof.
In the actual work of the capacitive touch screen, due to the working principle of the capacitive touch screen, the touch point group with the shorter distance can be identified as the same touch point by the capacitive touch screen. Therefore, the touch electrodes coupling the first signal electrode and the second signal electrode are required to be arranged closely. Therefore, the target touch point C can be regarded as an equivalent touch point of the touch point group formed by the overlapping positions of the first signal electrodes x1 and x2 and the second signal electrodes y1 and y2, that is, after the excitation signals of the first signal electrodes x1 and x2 are gain-processed and fed back to the second signal electrodes y1 and y2, the mutual capacitance at the overlapping positions of the first signal electrodes x1 and x2 and the second signal electrodes y1 and y2 is actually changed to form 4 touch points, and the formed 4 touch points are close to each other and are recognized as the same touch point, that is, the target touch point C, by the capacitive touch screen. By adjusting the weight of the gain component of the first signal electrodes x1 and x2 and the second signal electrodes y1 and y2, the simulated touch at any position in the area surrounded by the first signal electrodes x1 and x2 and the second signal electrodes y1 and y2 can be realized.
S204: performing gain processing on the excitation signal of the corresponding first signal electrode in the first signal electrode group by using the obtained target gains to generate a plurality of feedback signals;
the content of this step has been described in detail in the above step, and is not described herein again.
S205: feeding back a feedback signal to a corresponding second signal electrode in a second signal electrode group so as to simulate a touch target touch point;
in this embodiment, after the excitation signal is converted into the feedback signal, the feedback signal needs to be fed back to the corresponding second signal electrode in the second signal electrode group, so as to cause the size of the mutual capacitance at the overlapping position of the first signal electrode in the first signal electrode group and the second signal electrode in the second signal electrode group to change, and the mutual capacitance is detected by the capacitive touch screen, thereby realizing the simulation of the touch 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 to at least a portion of the second signal electrodes 12 on the capacitive touch screen 1 in advance, and the second signal electrodes 12 in the group of the second signal electrodes 12 corresponding to the target touch point are selected from the coupled second signal electrodes 12, and the feedback signal is fed back to the corresponding second signal electrodes 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 area defined by the first signal electrodes and the second signal electrodes 12 is the 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, B. If all the first signal electrodes 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.

In addition, the first signal electrodes 61 and the second signal electrodes on the capacitive touch screen 6 are not provided with touch electrodes one by one, but are provided at intervals.

The target touch point which can simulate the touch of the touch control device is positioned in the simulated touch area.
Please refer to fig. 13. Further, the touch device includes a gain processing circuit 43, and a gain processor 431 is disposed in the gain processing circuit 43 for each pair of the first signal electrode 71 and the second signal electrode 72, and is used for performing gain processing on the excitation signal of the corresponding first signal electrode 71. The target gain used by the gain processor 431 for processing the excitation signal is the superposition of the gain components corresponding to the first signal electrode 71 as the sender of the excitation signal and the second signal electrode 72 as the receiver thereof. The essence of the gain processor 431 may be an operational amplifier circuit, each gain processor 431 is connected to its corresponding first signal electrode 71 and second signal electrode 72, and the gain processing circuit 43 may be implemented by, for example, an MCU, an FPGA, a CPLD, a switch circuit, etc., and is used to control whether each gain processor 431 operates or is connected to its corresponding first signal electrode 71 and second signal electrode 72 by means of a software program or a hardware circuit.
It should be noted that the gain processing circuit 43 shown in fig. 13 is only one specific implementation, and in other embodiments, the circuit structure may be changed according to actual requirements, and is not limited to this embodiment.
