[0002] In the field of touch control, flat touch is an important human-computer interaction method for screen display terminals. Its important component is the touch sensor. Common touch principles include capacitive, resistive, electromagnetic, infrared, etc. In terms of structure, touch sensors are basically embedded in the display terminal. However, traditional screen touch is non-independent, which makes it impossible to expand the touch function of non-touch function display terminals.

[0003] In the prior art, a circuit frame is configured outside the display screen, and infrared tubes are arranged on the four sides of the circuit frame, so as to use the cooperation of each infrared tube to identify the touched point on the non-touch function display terminal. However, the use of the frame can only be applied to a single display screen, and cannot be adjusted for displays of different sizes, resulting in a relatively single use and poor flexibility in expanding touch. Summary of the invention

[0004] The purpose of the present invention is to at least provide a touch device, a display device and a touch recognition method thereof, which can at least solve the problem of how to adapt to display screens of different sizes for use, at least improve the flexibility and applicability of use, and facilitate reuse on different display devices.

[0005] To solve the above technical problems, at least one embodiment of the present application provides a touch device, including:

[0006] A winding body that can be wound; the winding body is evenly arranged with a plurality of signal transmitting parts and a plurality of signal receiving parts in a single row;

[0007] The winding body is used to wrap around the edge of the touch area so that the multiple signal transmitting parts and the multiple signal receiving parts are aligned one by one in position. The receiving and transmitting signals formed after the alignment pass through the touch area.

[0008] and a control module connected to the signal transmitting unit and the signal receiving unit, for receiving the receiving and transmitting signals fed back by the signal transmitting unit and the signal receiving unit, and identifying the touch coordinates of the touched area according to the receiving and transmitting signals.

[0011] Acquire the receiving and transmitting signals fed back by the signal transmitting units and the signal transmitting units around the edge of the touch control area;

[0012] A touched coverage area when a user touches the touch area is determined according to a signal transceiver path of the acquired transceiver signal in the touch area, and touch coordinates of the touch area are identified according to the touched coverage area.

[0013] At least one embodiment of the present application also provides an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the above-mentioned touch recognition method.

[0014] At least one embodiment of the present application further provides a computer-readable storage medium storing a computer program, wherein the computer program implements the above-mentioned touch recognition method when executed by a processor.

[0015] The embodiments of the present application provide a touch device and a touch recognition method thereof. A winding body can be used to wrap around display devices of different specifications, so that the winding body wraps around the touch area in the display screen of the display device. The winding effect of the winding body can be matched according to the size and shape of the touch area, so that the touch position is identified by the signal transmitting part and the signal receiving part, so that the control module identifies the touch coordinates, so that the user's touch on a certain point in the touch area can be recognized by the signal transmitting part and the signal receiving part at the outer edge of the screen surrounded by the winding body, thereby conveniently adding a touch function to the outside of the display terminal, and can be adapted to display screens of different sizes for use, thereby improving the flexibility and applicability of use, and facilitating reuse on different display devices.

[0016] In some optional embodiments, a data connector is further included on the winding body, one end of which is connected to the control module, and the other end is used to connect to the display terminal to transmit the touch coordinates sent by the control module to the display terminal for response. The data connector facilitates the connection between the winding body and the display terminal, so that the touch coordinates are fed back to the display terminal for response, without the need to modify the display terminal, thereby improving ease of use and being reusable on different display devices.

[0017] In some optional embodiments, the touch area is rectangular; the distance between the two adjacent signal transmitters and / or the signal transmitter to the corner point on the winding body is kept consistent. By limiting the application to rectangular scenes, it is convenient to make the transmitters and receivers on the opposite sides correspond one-to-one, reducing the difficulty of touch recognition, and by keeping the corner point consistent with the distance between the previous signal transmitter and the signal receiver, as well as the distance between the next signal transmitter and the signal receiver, it is ensured that the transmitter and the receiver can correspond one-to-one to each other in relative positions, facilitating accurate touch recognition.

[0018] In some optional embodiments, the winding body is provided with an inflection point mark at the midpoint between each adjacent two signal transmitting parts and / or signal receiving parts, which is used as the turning point of the winding body when surrounding the touch area. By setting the inflection point mark, it is convenient for the user to turn the winding body at the corner of the touch area domain through the corner mark when surrounding the display terminal, thereby improving the convenience of operation.

[0019] In some optional embodiments, the signal transmitting unit includes an infrared transmitting unit; the signal receiving unit includes an infrared receiving unit; and the areas on the winding body other than the positions of the signal transmitting unit and the signal receiving unit are all light-shielding areas. By setting up the light-shielding area, it is possible to prevent light from leaking out or in, ensuring that the transmission and reception cooperation between the infrared transmitting unit and the receiving unit is not affected by other light, thereby improving the accuracy of touch recognition.

By analyzing the total number of signal transmitting parts and signal receiving parts in the touch area and the number of signal transmitting parts and signal receiving parts on a single side, the number and length of signal transmitting parts and signal receiving parts on each side of the rectangular touch area can be determined, thereby facilitating the determination of the coordinate system, providing calculation parameters for subsequent touch coordinates, and improving the accuracy of touch recognition. It can automatically identify the specifications of display devices of different sizes, thereby providing a corresponding touch recognition coordinate system for calculation. It is simple and convenient to use, and can quickly adapt to different display devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0038] In order to facilitate understanding of the embodiments of the present application, relevant contents about the touch device are first introduced here.

[0039] In the field of touch control, flat touch is an important human-computer interaction method for screen display terminals. Its important component is the touch sensor. Common touch principles include capacitive, resistive, electromagnetic, infrared, etc. In terms of structure, touch sensors are basically embedded in the display terminal. However, traditional screen touch is non-independent, which makes it impossible to expand the touch function of non-touch function display terminals.

[0040] In the prior art, a circuit frame is configured outside the display screen, and infrared tubes are arranged on the four sides of the circuit frame, so that the cooperation of each infrared tube can be used to identify the touched point on the non-touch function display terminal. However, the use of the frame can only be applied to a single display screen, and it cannot be adjusted and adapted to displays of different sizes, resulting in a relatively simple use and poor flexibility in expanding touch. Moreover, after the existing infrared touch device is installed outside the display screen, it is unable to identify the length and width of the display plane, resulting in the need to manually input the corresponding parameter information on the device in order to identify the actual touch point position. The use is more troublesome and the manual input has problems such as poor adaptability, which easily leads to inaccurate touch.

[0041] In order to solve the above-mentioned technical problem that the touch device can only be applied to a single display screen and cannot be adjusted and adapted to displays of different sizes, resulting in a relatively single use and poor flexibility in expanding touch, the present invention proposes a touch device. The implementation details of the touch device of this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0042] Embodiment 1:

[0043] The implementation details of the touch control device of this embodiment are described in detail below. The following content is only provided for the convenience of understanding the implementation details and is not necessary for implementing this solution. The schematic diagram of the touch control device of this embodiment can be as follows: Figure 1 and Figure 2 As shown, it includes a winding body 1, a plurality of signal transmitting parts 2 and a signal receiving part 3, and a control module 4. Among them, the plurality of signal transmitting parts 2 and the signal receiving part 3 are arranged on the winding body 1, and the winding body 1 is used to wrap around the edge of the touch area so that the plurality of signal transmitting parts 2 and the plurality of signal receiving parts 3 are opposite to each other in position, and the receiving and transmitting signals formed after they are opposite to each other pass through the touch area; the control module 4 is connected to each signal transmitting part 2 and the signal receiving part 3, and is used to receive the receiving and transmitting signals fed back by the signal transmitting part 2 and the signal receiving part 3, and identify the touch coordinates of the touched area according to the receiving and transmitting signals.

[0044] Furthermore, multiple signal transmitting parts 2 and multiple signal receiving parts 3 can be evenly or unevenly arranged on the winding body 1, and the number of signal receiving parts 3 between the previous signal transmitting part 2 and the next signal transmitting part 2 is greater than or equal to 1, which can be set according to actual needs. In this embodiment, in order to facilitate the signal transmitting parts 2 and the signal receiving parts 3 on the edge of the touch area of ​​the winding body 1 to face each other, the signal transmitting parts 2 and the signal receiving parts 3 are alternately and evenly arranged on the winding body 1 in turn to improve the convenience of use.

[0045] It can be understood that the touch area is the display area of ​​the display terminal, so that after the winding body 1 surrounds the display terminal, the display area of ​​the display terminal is surrounded by various signal transmitting parts 2 and signal receiving parts 3 to facilitate touch recognition. The reel 1 can be wound around display terminals of different specifications, so as to cooperate with the signal transmitting and receiving parts 2 and 3 and the recognition of the control module 4 to realize touch control of display terminals without touch function, and can be adapted to display screens of different sizes for use, thereby improving the flexibility and applicability of use, and facilitating reuse on different display devices.

[0046] Specifically, the signal transmitting part 2 can be an infrared transmitting unit or an ultrasonic transmitting unit, and the signal receiving part 3 is set corresponding to the transmitting signal of the transmitting end. In this embodiment, the infrared transmitting unit is taken as an example, that is, in this embodiment, the signal transmitting part 2 is an infrared transmitting unit, and the signal receiving part 3 is an infrared receiving end. When not blocked, the signal receiving part 3 can normally receive the infrared rays emitted by the signal transmitting part 2. When the touch area is touched, the signal receiving part 3 is blocked and cannot receive the infrared signal emitted by the signal transmitting part 2, so as to identify the touched position by using the information of the sending and receiving signals, and identify the touch coordinates in combination with the control module 4.

[0047] Further, such as Figure 1 As shown, in order to improve the accuracy of the coordination between the signal transmitting part 2 and the signal receiving part 3, the areas on the winding body 1 except for the positions of the signal transmitting part 2 and the signal receiving part 3 are all shading areas, preventing the infrared light emitted by the infrared transmitting unit from passing through and avoiding external light from entering, thereby ensuring the accuracy of the coordination between the signal transmitting part 2 and the signal receiving part 3 in the touch area, and thus improving the accuracy of touch coordinate recognition.

[0048] Specifically, the control module 4 is also used to identify the number of the signal transmitting parts 2 and the signal receiving parts 3 surrounding the edge of the touch area and the size of the touch area according to the transceiver signals passing through the touch area, so as to facilitate the determination of the coordinate system, provide calculation parameters for subsequent touch coordinates, improve the accuracy of touch recognition, and automatically identify the specifications of display devices of different sizes, thereby providing a corresponding touch recognition coordinate system for calculation. It is simple and convenient to use and can quickly adapt to different display devices.

[0049] In some embodiments, Figure 2 and Fig.11 As shown, the touch device also includes a data connector 5 provided on the winding body 1, one end of the data connector 5 is connected to the control module 4, and the other end is used to connect to the display terminal to transmit the touch coordinates sent by the control module 4 to the display terminal for response; the touch area includes the display area of ​​the display terminal. The winding body 1 is conveniently connected to the display terminal through the data connector 5, so that the touch coordinates are fed back to the display terminal for response, without the need to modify the display terminal, thereby improving the ease of use, and can be reused on different display devices.

[0050] In this embodiment, the data connector 5 can be a USB connector to facilitate connection with different display terminals. In other embodiments, the control module 4 can also be connected to the display terminal through Bluetooth or network signals, so that the touch coordinates recognized by the control module 4 are sent to the display terminal for response.

[0051] Further, such as Figure 2 and Figure 3 As shown, the touch area is a rectangle, which means that the touch device is mainly used on a rectangular display terminal, so that the transmitter and the receiver on the two opposite sides correspond to each other. At the same time, in order to ensure that the transmitter and the receiver on the opposite sides of the touch area correspond to each other, the distance between the two adjacent signal transmitters 2 and / or the signal transmitter 2 to the corner point on the winding body 1 is kept consistent, so that after the winding body 1 surrounds the touch area, it is ensured that each signal transmitter 2 at the edge of the touch area can be opposite to the signal receiver 3, thereby improving the touch recognition effect.

[0052] Specifically, the winding body 1 is provided with an inflection point mark 6 at the midpoint between each adjacent two of the signal transmitting parts 2 and / or signal receiving parts 3, which is used as the turning point of the winding body 1 when surrounding the touch area. Therefore, when the winding body 1 surrounds the display terminal, it is convenient to directly identify the turning point through the inflection point mark 6 for easy operation. Among them, if the signal transmitting part 2 and the signal receiving part 3 are just separated by the corner of the display terminal when the winding body 1 is used to surround the display terminal, the winding body 1 will continue to execute until the next turning point mark 6 is displayed before turning; if the display mark does not appear at the corner of the display terminal when the winding body 1 is used to surround the display terminal, the winding body 1 will continue to execute until the next turning point mark 6 is displayed before turning; if the display mark appears beyond the corner of the display terminal when the winding body 1 is used to surround the display terminal, the winding body 1 will continue to execute until the next turning point mark 6 is displayed before turning; through the above method, it can be ensured that the two opposite sides of the touch area are completely overlapped, so that the signal transmitting part 2 on one side of the touch area can be directly opposite to the signal receiving part 3 on the opposite side. In this embodiment, it can be understood that when the spacing between two adjacent signal transmitting parts 2 and signal receiving parts 3 is designed to be small enough, such as less than half the width of a finger, it can be regarded as a finger manipulation error, and the size of the winding body 1 is regarded as the size of the touch area of ​​the display terminal.

[0053] In some embodiments, in order to facilitate the positioning of the cable winding body 1 outside the display terminal, a positioning structure for detachably fixing the cable winding body 1 to the outer edge of the touch area is also provided on the cable winding body 1. Exemplarily, the positioning structure can be any one of a suction cup, a magnet, or an adhesive, so that the cable winding body 1 can be conveniently positioned on the display terminal when it is wrapped around, and can be directly removed by applying force when disassembling, and can be reused, thereby improving the convenience of operation and use.

[0054] The touch device provided in this embodiment can be wrapped around display devices of different specifications by utilizing the winding body 1, so that the winding body 1 wraps around the touch area in the display screen of the display device, and the winding effect of the winding body 1 can be matched according to the size and shape of the touch area, so that the touch position is identified by the signal transmitting part 2 and the signal receiving part 3, so that the control module 4 identifies the touch coordinates, so that the user's touch on a certain point in the touch area can be recognized by the signal transmitting part 2 and the signal receiving part 3 at the outer edge of the screen surrounded by the winding body 1, so as to conveniently add a touch function to the outside of the display terminal, and can be adapted to display screens of different sizes for use, thereby improving the flexibility and applicability of use, and facilitating reuse on different display devices. In addition, this type of touch device can also determine the number and length of signal transmitting parts 2 and signal receiving parts 3 on each side of the rectangular touch area by analyzing the number of signal transmitting parts 2 and signal receiving parts 3 in the touch area and the number of signal transmitting parts 2 and signal receiving parts 3 on a single side of the touch area, thereby facilitating the determination of the coordinate system, providing calculation parameters for subsequent touch coordinates, and improving the accuracy of touch recognition. It can automatically identify the specifications of display devices of different sizes, thereby providing a corresponding touch recognition coordinate system for calculation. It is simple and convenient to use, and has the advantage of being able to quickly adapt to different display devices.

[0055] Embodiment 2

[0056] On the basis of the first embodiment, this embodiment further provides a touch recognition method, which is implemented by the touch device in the first embodiment; the touch recognition method of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities, and its specific process can be as follows: Figure 4 As shown, the touch recognition method includes:

[0057] Step 101, acquiring the receiving and transmitting signals fed back by the signal transmitting units and the signal transmitting units around the edge of the touch area;

[0058] Specifically, after the winding body wraps around the display terminal, a touch area corresponding to the display interface of the display terminal is formed. At this time, only the signal transmitting parts at the edge of the touch area can be aligned with the signal receiving parts on the opposite side. In the initial stage, the signal transmitting parts and signal receiving parts on the winding body can be opened, so that only the signal transmitting parts and signal receiving parts located in the touch area can generate transmission and reception signals. In this way, the signal transmitting parts and signal receiving parts that generate transmission and reception signals can be recorded, so that when the user touches the touch screen, the touch signal fed back by the recorded touch sensing module can be identified, so as to accurately identify the touch information.

[0059] In some examples, when the user touches the display area of ​​the display terminal (i.e., the touch area in this embodiment), due to the blocking effect of the finger, part of the signal receiving part at the edge of the touch area cannot receive the signal transmitted by the signal transmitting part, thereby causing it to feedback the touch signal, thereby facilitating the next step of identifying the touch coordinates.

[0060] Step 102, determining a touched coverage area when a user touches the touch area according to a signal transceiver path of the acquired transceiver signal in the touch area, and identifying touch coordinates of the touch area according to the touched coverage area.

[0061] Specifically, when the user touches the touch area to generate a touch signal, some touch sensing modules in the horizontal and vertical directions within the touch area both generate touch signals, and the overlapping area of ​​the two is determined as the non-touched coverage area, so that the midpoint of the touched coverage area is identified as the touch coordinates of the touched area, so as to facilitate transmission to the display terminal for response.

[0062] In this embodiment, by acquiring the touch signals fed back by the various signal transmitting parts and the signal receiving parts in the touch area surrounded by the winding body, the position coordinates of the touched point in the touch area can be accurately identified, so that the winding body surrounds different display terminals and can be identified by the signal transmitting parts and the signal receiving parts used by the edges of the touch area surrounded by the winding body, thereby conveniently adding a touch function to the outside of the display terminal and being able to adapt to display screens of different sizes for use, thereby improving flexibility and applicability of use and facilitating reuse on different display devices.

[0063] In some embodiments, the touch area is a rectangle. Before executing step 101, Figure 5 As shown, the touch recognition method also includes:

[0064] Step 001, obtaining the starting receiving and sending signals fed back by the signal transmitting parts and the signal transmitting parts around the edge of the touch area of ​​the winding body;

[0065] In some embodiments, after the winding body is wrapped around the outer edge of the screen of the display terminal to form a touch area, the redundant signal transmitting parts and signal receiving parts at the head and tail ends of the winding body are moved away from each other, thereby starting each signal transmitting part and signal receiving part on the winding body, so that each signal transmitting part and signal receiving part only located in the touch area can sense each other to generate receiving and transmitting signals. After obtaining the receiving and transmitting signals of each signal transmitting part and signal receiving part in the touch area, each signal transmitting part and signal receiving part at the edge of the touch area can be compiled as 1 for recording, so as to facilitate the subsequent identification of touch coordinates only for the signals generated by each signal transmitting part and signal receiving part in the touch area.

[0066] Step 002: determining the number of signal transmitting parts and signal receiving parts used by the winding body to surround the touch area based on the starting transceiver signal;

[0067] Step 003: Acquire the unilateral transmission and reception signals of each signal transmitting unit and signal receiving unit on a pair of opposite sides of the touch area.

[0068] In some embodiments, any single side of the touch area can be blocked by an opaque material so that only one pair of opposite signal transmitting parts and signal receiving parts on the touch area can transmit and receive normally, thereby facilitating the acquisition of feedback signals from each signal transmitting part and signal receiving part on any single side of the touch area.

[0069] Step 004: determining the number of signal transmitting parts and signal receiving parts on the single side of the touch area based on the single-side signal receiving and transmitting;

[0070] Step 005: Determine the size of the touch area by using the number of signal transmitting parts and signal receiving parts used by the winding body to wrap around the touch area and the number of signal transmitting parts and signal receiving parts on the single side of the touch area.

[0071] In some embodiments, the system pre-enters the spacing between two adjacent signal transmitters and signal receivers, so that the length and width of the touch area can be calculated based on the number of signal transmitters and signal receivers. Therefore, in step 005, the number of signal transmitters and signal receivers used by the winding body to wrap around the touch area and the number of signal transmitters and signal receivers on the single side of the touch area are first used to determine the number of signal transmitters and signal receivers on each side of the touch area, and the number of signal transmitters and signal receivers on each side can be used to calculate the length of each side, thereby identifying the length and width of the touch area, facilitating the determination of the coordinate system, providing calculation parameters for subsequent touch coordinates, and improving the accuracy of touch recognition. The specifications of display devices of different sizes can be automatically identified, thereby providing a corresponding touch recognition coordinate system for calculation. It is simple and convenient to use, and has the advantage of being able to quickly adapt to different display devices.

[0072] Embodiment three:

[0073] This embodiment provides exemplary contents of the first embodiment and the second embodiment, that is, provides an exemplary process of using a touch device and a touch recognition method, such as Figure 6-Figure 11 The specific contents include:

[0074] 1. Insert the USB of the cord (i.e. the winding body) into the burner, set the actual distance constant d between adjacent infrared units (i.e. the signal transmitting part and the signal receiving part), set the transmitting switching frequency of the infrared transmission x1, x2, x3 to x2a+2b-2, x2a+2b-1, x2a+2b to constants (f1, f2, f3 to f2a+2b-2, f2a+2b-1, f2a+2b), set the lower left corner as the coordinate 0 point, and write these parameters into the memory of the cord MCU (i.e. the control module of the winding body).

[0075] 2. Align the first infrared unit (x1, y1) of the touch cable with a right angle to a display edge of the display, with the infrared LED facing the display area, and stick it around the edge of the display area clockwise or counterclockwise to fix it. Figure 7 As shown, for a display screen of a certain size, a and b are relatively fixed values, 2a+2b≦n.

[0076] Among them, when the string is pasted along the horizontal direction and then turned to the vertical direction, there will be a 90° right angle, ensuring that the distance between this right angle and the previous infrared unit and the next infrared unit is d / 2. Similarly, when the vertical direction turns to the horizontal direction, the distance between the second 90° right angle and the previous infrared unit and the next infrared unit is also d / 2. The same is true for the third right angle. (If the distance from the corner to the previous infrared unit is greater than d / 2, and the distance to the next infrared unit is less than d / 2, you can paste one more infrared unit in the horizontal direction and then turn the corner at d / 2). The above method ensures that the infrared transmitting unit and the receiving end are in a one-to-one relative position. Doing so will theoretically make the area surrounded by the string larger than the display area by a maximum length and width of d. However, when d is relatively small, it can be understood that d is an acceptable detection error.

[0077] Specifically, Figure 8 As shown, when the rope encounters a corner, if the transmission and reception of the infrared unit of the rope are separated by the corner, the rope continues to go straight until it reaches a distance of d / 2 from the next infrared unit before turning the first corner. It can be understood that at this time, the side length of the rope is d / 2 longer than the side length of the display area. Similarly, when the rope passes the second display corner and cannot exactly correspond to the distance d / 2 between the two infrared units, there are two cases. When the display angle does not exceed the midpoint of the rope d / 2, the rope continues to go straight to d / 2 and turns the second corner. When the display angle exceeds the midpoint of d / 2, the rope continues to go straight through an infrared unit, and then continues to go straight to d / 2 and turns the second corner. The length from the second corner to the third corner is equal to the distance from the starting point to the first corner, and the distance from the third corner to the end point (starting point) is equal to the distance from the first corner to the second corner, and both can ensure that the corners are turned at d / 2, and two rope edges completely overlap with the display area edges. Therefore, the relationship between the area around which the rope is wrapped and the display area can be seen in Figure 8As shown. It can be calculated that when the area around the rope exceeds the display area in both horizontal and vertical directions, its size does not exceed d. When the spacing d is designed to be small enough, such as less than half the width of a finger, it can be treated as a finger manipulation error, and the size of the rope around it can be regarded as the size of the display area.

[0078] 3. Insert the touch cable USB into the USB port of the above display terminal controller. The touch cable gets power and starts working. Fig.12 As shown, the MCU turns on the transmission and reception of the infrared unit (x1, y1) to (xn, yn), and maintains the infrared transmission LED to transmit at the initial frequency f0. At this time, each infrared receiving tube can receive the transmission signal on the opposite side, and any infrared transmission signal from x1 to x2a+2b can be detected by one of the receiving tubes from y1 to y2a+2b. The MCU records the registers that have detected infrared signals in the order of y1, y2, y3, ..., y2a+2b as 1. Adding all 1s can calculate Figure 7 The number of emission units used in the enclosed display area shown is 2a+2b or a+b.

[0079] 4. Use black tape to stick the inner frame of the infrared transmitting and receiving unit on one side of the cord (the edge of the screen display area). Figure 7 As shown, the horizontal infrared unit (x1, y1) is glued to the infrared unit (xa, ya). At this time, the MCU will record the registers that have detected infrared signals in the order of y1, y2, y3, ..., y2a+2b as 1. Adding all 1s can calculate Figure 7 The number of transmitting units used in the longitudinal direction of the enclosed display area is 2b. From step 3, 2a or a can be calculated. Steps 3 and 4 are steps for identifying the length and width of the display plane surrounded by the wire rope touch control.

[0080] 5. Remove the black tape and restore the state completed in step 2. The cord is now in normal working condition.

[0081] 6. Touch any position of the display surface with your finger. Due to the light blocking effect of the finger, such as Fig. 9 and Fig.10 As shown, the MCU detects the corresponding horizontal Y3a+2b+1-α, Y3a+2b+1-ɡ and vertical yβ, yθ infrared receiving tubes, and cannot detect the infrared signal emitted from the opposite side. The area where the vertical Yα and the horizontal Y2a+b+1-β and the vertical y2a+b+1-θ overlap is the finger coverage area, and its center point is the finger contact point C. (where θ, β≦a / α, ɡ≦b)

[0082] 7. MCU calculates the position of finger contact point C: Fig.11As shown, through steps 3 and 4, a and b are calculated. MCU calculates that the coordinates corresponding to the contact C are X = d*(β+θ) / 2, Y = d*(a+b-α+(a+b-ɡ)) / 2 = d*(2a+2b-α-ɡ) / 2.

[0083] 8. MCU transmits the X / Y coordinates of the contact C calculated in step 7 to the USB data interface, such as Fig.11 As shown, it is transmitted to the display terminal, and the display terminal responds to the click touch action.

[0084] If you need to match other display screens, you can lift the rope and repeat steps 2 to 8.
