Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic device technology, and more particularly to a conductive grid radio frequency control module, system, and method for simulating and serving as a radio frequency antenna by controlling the conductive sensor grid structure of an existing touch panel, as well as a touch panel containing the same. Background Technology
[0002] With the popularization of applications such as mobile payment, smart access control, electronic tickets, smart tags, identity recognition and data exchange, Near Field Communication (NFC) technology has been widely used in electronic products such as smartphones, POS terminals, SCO terminals, tablets and wearable devices. NFC technology usually operates in the 13.56MHz ISM high frequency (HF) band, and its principle is to use magnetic coupling for contactless short-range communication.
[0003] In existing technologies, NFC antennas are typically designed as a planar spiral coil or a multi-turn loop, generally fabricated by etching away the copper conductive layer on a printed circuit board. When NFC operates, the NFC control chip in the initiating device first generates a 13.56MHz alternating current and transmits it to the NFC antenna, thereby creating an alternating magnetic field around the antenna. When a target device enters this magnetic field, a corresponding induced current is generated, driving the internal components of the target device to operate, thus achieving power transfer or data exchange. Typical NFC antenna sizes can range from a few square centimeters to tens of square centimeters, depending on the size of the application device.
[0004] On the other hand, touchscreens are now standard equipment in various electronic products. Regarding touch panels, the mainstream technology is currently projected capacitive (PCAP) touch panels. The core structure of a PCAP touch panel includes a matrix-like conductive grid made of transparent conductive material. This grid consists of two layers of insulated electrodes. The driving electrodes are typically located on the lower layer, and the sensing electrodes are typically located on the upper layer. These two sets of electrodes are arranged orthogonally to form the matrix grid structure. The linewidth or pitch of the conductive grid can be as small as micrometers, depending on the resolution. Touch panels used in smartphones or tablets may range in size from 5 inches to 12 inches, while those used in larger machines such as POS terminals and SCO terminals may range in size from 17 inches to 24 inches or larger.
[0005] The operating principle of the PCAP touch panel is as follows: When the controller sequentially applies AC voltage signals to the driving electrodes, a tiny mutual capacitance is formed at the intersection of each driving electrode and the sensing electrode. When the user's finger approaches or touches the panel surface, it interferes with the electric field around the intersection, causing the mutual capacitance value at the intersection to decrease. The controller detects the change in mutual capacitance value by scanning the entire array of sensing electrodes and locates the intersection where the mutual capacitance value changes significantly as the touch position.
[0006] NFC antennas and touch panels are two seemingly unrelated components, with different functions, structures, and applications. However, integrating the conductive grids of the NFC antenna and touch panel, through sharing a conductive grid or conductive layer, could not only simplify product structure, save space and cost, but also potentially develop a completely new component. However, to date, such a novel structural integration method has not yet appeared in related technological fields or commercially available products.
[0007] Therefore, in view of the shortcomings of the prior art, the inventor, through careful attempts and research, and with a persistent spirit, finally conceived the present invention, "Conductive Grid Radio Frequency Control Module, System and Method and Touch Panel Including the Therein", which can overcome the above-mentioned shortcomings. The following is a brief description of the present invention. Summary of the Invention

[0079] Figure 1 A top view schematic diagram of the conductive mesh radio frequency control module included in this invention is shown. Figure 2This diagram illustrates a side cross-sectional view of the conductive mesh structure included in this invention. The conductive mesh radio frequency control module 10 proposed in this invention preferably includes a conductive mesh 100 and a radio frequency controller module 200. The conductive mesh 100 preferably includes a driving wire layer 110, a light-transmitting insulating layer 120, and a sensing wire layer 130. The driving wire layer 110 preferably includes multiple driving wires Tn arranged parallel to the x-axis direction, and the sensing wire layer 130 preferably includes multiple sensing wires Rn arranged parallel to the y-axis direction. Preferably, the driving wire layer 110 is disposed below the sensing wire layer 130, and the sensing wire layer 130 is disposed above the driving wire layer 110. A light-transmitting insulating layer 120 is disposed between the driving wire layer 110 and the sensing wire layer 130 to prevent direct contact between them.
[0080] Multiple driving wires Tn and multiple sensing wires Rn are disposed on a substrate 140, which is preferably, but not limited to, a glass substrate or other transparent substrate. The multiple driving wires Tn and multiple sensing wires Rn are separated by a light-transmitting insulating layer 120, and there is no electrical connection between them. In this embodiment, the multiple driving wires Tn and multiple sensing wires Rn are orthogonally arranged in space, but the multiple driving wires Tn and multiple sensing wires Rn may also intersect at other angles in space, such as, but not limited to, 30°, 45° or 60°.
[0081] In one embodiment, the multiple driving wires Tn and multiple sensing wires Rn are preferably made of transparent conductive oxide (TCO), such as, but not limited to, indium tin oxide (ITO), nanowires, silver nanowires, or other conductive and transparent materials.

The RF controller module 200 is configured to generate RF carrier signals with an operating frequency.
[0084] Figures 3 to 7 A schematic diagram illustrating the control principle of the first embodiment of the present invention is shown. Figure 3 A schematic diagram of the composite waveform of multiple radio frequency carrier signals generated by the radio frequency controller module after superposition is shown in the first embodiment of the present invention; Figure 4 A schematic diagram illustrating the application of multiple radio frequency carrier signals to a first-turn coil to form a rotating alternating magnetic field, as shown in the first embodiment; Figure 5 A schematic diagram illustrating the application of multiple radio frequency carrier signals to the second coil to form a rotating alternating magnetic field, as shown in the first embodiment; Figure 6 A schematic diagram illustrating the application of multiple radio frequency carrier signals to a third-turn coil to form a rotating alternating magnetic field, as disclosed in the first embodiment; and Figure 7 A schematic diagram of the structure of an antenna element simulated by implementing the first embodiment of the present invention is shown.
[0085] The first embodiment preferably provides a conductive grid radio frequency control method, particularly an in-phase segmented temporal sequence radio frequency control method. In the first embodiment, the conductive grid 100 is preferably configured to simulate, for example, but not limited to, an NFC / RFID antenna with a three-turn planar loop coil. Preferably, the conductive grid 100 is configured to use a first drive wire T1, a first sensing wire R1, a second drive wire T2, and a second sensing wire R2 as a first turn coil L1 to simulate the first turn of the planar loop coil of the NFC / RFID antenna; to use a third drive wire T3, a third sensing wire R3, a fourth drive wire T4, and a fourth sensing wire R4 as a second turn coil L2 to simulate the second turn of the planar loop coil of the NFC / RFID antenna; and to use a fifth drive wire T5, a fifth sensing wire R5, a sixth drive wire T6, and a sixth sensing wire R6 as a third turn coil L3 to simulate the third turn of the planar loop coil of the NFC / RFID antenna. The first turn coil or the first loop coil L1 has a relatively large inner diameter, and the third turn coil or the third loop coil L3 has a relatively small inner diameter.
[0086] In this embodiment, the radio frequency controller module 200 is configured to generate, as shown in the following example. Figure 3The multiple radio frequency carrier signals S1-S12 shown are each generated separately by the radio frequency controller module 200 and are independent radio frequency carrier signals. Each of these signals has a waveform of either a quarter-wavelength wave or a λ / 4 wave. However, when the multiple radio frequency carrier signals S1-S12 are aligned to the same phase and placed on the same coordinate waveform diagram, they will form a complete and continuous composite radio frequency carrier signal C based on a sinusoidal wave. The composite radio frequency carrier signal C has, for example, but not limited to, an operating frequency f of 13.56 MHz, a period of p, and a wavelength of λ. Alternatively, there may be no phase difference between each radio frequency carrier signal S1-S12, i.e., no phase difference. Degree refers to being in the same phase.
[0087] Preferably, the waveforms of the first radio frequency carrier signal S1, the fifth radio frequency carrier signal S5, and the ninth radio frequency carrier signal S9 are configured as waveforms of the first 1 / 4 wavelength or the first 1 / 4 period of a sine wave; the waveforms of the second radio frequency carrier signal S2, the sixth radio frequency carrier signal S6, and the tenth radio frequency carrier signal S10 are configured as waveforms of 1 / 4 wavelength or 1 / 4 period to 1 / 2 wavelength or the first 1 / 2 period of a sine wave; the waveforms of the third radio frequency carrier signal S3, the seventh radio frequency carrier signal S7, and the eleventh radio frequency carrier signal S11 are configured as waveforms of 1 / 2 wavelength or 1 / 2 period to 3 / 4 wavelength or the first 3 / 4 period of a sine wave; and the waveforms of the fourth radio frequency carrier signal S4, the eighth radio frequency carrier signal S8, and the twelfth radio frequency carrier signal S12 are configured as waveforms of 3 / 4 wavelength or 3 / 4 period to the full wavelength or the full period of a sine wave.
[0088] Preferably, the synthesized radio frequency carrier signal C includes a first-turn radio frequency carrier signal W1, a second-turn radio frequency carrier signal W2, and a third-turn radio frequency carrier signal W3. The first-turn radio frequency carrier signal W1 includes a first radio frequency carrier signal S1, a second radio frequency carrier signal S2, a third radio frequency carrier signal S3, and a fourth radio frequency carrier signal S4 applied to the first-turn coil L1. The second-turn radio frequency carrier signal W2 includes a fifth radio frequency carrier signal S5, a sixth radio frequency carrier signal S6, a seventh radio frequency carrier signal S7, and an eighth radio frequency carrier signal S8 applied to the second-turn coil L2. The third-turn radio frequency carrier signal W3 includes a ninth radio frequency carrier signal S9, a tenth radio frequency carrier signal S10, an eleventh radio frequency carrier signal S11, and a twelfth radio frequency carrier signal S12 applied to the third-turn coil L3.
[0089] The periods of the first turn RF carrier signal W1, the second turn RF carrier signal W2, and the third turn RF carrier signal W3 are all p. The amplitudes of the first turn RF carrier signal W1, the second turn RF carrier signal W2, and the third turn RF carrier signal W3 will gradually decrease over time to match the planar ring coil with a gradually decreasing inner diameter.
[0090] like Figure 4 As disclosed, the RF controller module 200 is configured to sequentially execute the following program: at time t = 0, a first RF carrier signal S1 is applied to the first drive wire T1 from position ①; at time t = P / 4, a second RF carrier signal S2 is applied to the first sensing wire R1 from position ②; at time t = P / 2, a third RF carrier signal S3 is applied to the second drive wire T2 from position ③; and at time t = 3P / 4, a fourth RF carrier signal S4 is applied to the second sensing wire R2 from position ④. This generates a clockwise rotating alternating magnetic field RAMF1 within the rectangular area formed by the first coil L1, thereby transmitting the wireless RF carrier signal and achieving the effect of generating a simulated first loop coil of an NFC / RFID antenna through the first coil L1.
[0091] like Figure 5 As disclosed, the RF controller module 200 is configured to continue executing the following program sequentially: at time t = P, the fifth RF carrier signal S5 is applied to the third drive wire T3 from position ⑤; at time t = P + P / 4, the sixth RF carrier signal S6 is applied to the third sensing wire R3 from position ⑥; at time t = P + P / 2, the seventh RF carrier signal S7 is applied to the fourth drive wire T4 from position ⑦; and at time t = P + 3P / 4, the eighth RF carrier signal S8 is applied to the fourth sensing wire R4 from position ⑧. This generates a clockwise rotating second alternating magnetic field RAMF2 within the rectangular area formed by the second coil L2, transmitting the wireless RF carrier signal. This achieves the effect of generating a simulated second planar loop coil of an NFC / RFID antenna through the second coil L2. The magnetic field strength of the second alternating magnetic field RAMF2 is slightly less than the magnetic field strength of the first alternating magnetic field RAMF1.
[0092] like Figure 6 As disclosed, the RF controller module 200 is configured to continue executing the following program sequentially: at time t = 2P, the ninth RF carrier signal S9 is applied to the fifth drive wire T5 from position ⑨; at time t = 2P + P / 4, the tenth RF carrier signal S10 is applied to the fifth sensing wire R5 from position ⑩; at time t = 2P + P / 2, the tenth RF carrier signal S10 is applied to the fifth sensing wire R5 from position ⑩. The eleventh radio frequency carrier signal S11 is applied to the sixth drive wire T6. At time t = 2P + 3P / 4, from position... The twelfth radio frequency carrier signal S12 is applied to the sixth induction wire R6. This generates a clockwise rotating third alternating magnetic field RAMF3 within the rectangular area formed by the third coil L3 and its surroundings, thereby transmitting the radio frequency carrier signal. This achieves the effect of generating the third planar loop coil of an NFC / RFID antenna through the third coil L3. The magnetic field strength of the third alternating magnetic field RAMF3 will be slightly less than that of the second alternating magnetic field RAMF2.
[0093] When the RF controller module 200 successfully applies multiple RF carrier signals S1-S12 sequentially to the first coil L1, the second coil L2, and the third coil L3 included in the conductive grid 100, it is equivalent to forming a grid like... Figure 7 The disclosed radio frequency antenna simulation unit 20 with a three-turn planar loop coil, which can be used to transmit radio frequency carrier signals with a frequency of 13.56 MHz, can be used to simulate, for example, but not limited to, an NFC / RFID antenna with a three-turn planar loop coil.
[0094] Preferably, the RF controller module 200 is configured to generate a first RF carrier signal S1 to a twelfth RF carrier signal S12, thereby forming a composite RF carrier signal C. This stacks an NFC electric field or a 13.56MHz RF carrier signal in the conductive grid 100, particularly in the area and around the annular coil formed by the first turn coil L1 to the third turn coil L3, and an overall rotating alternating magnetic field that presents a clockwise rotation.
[0095] In the first embodiment, such as Figure 7 As disclosed, the RF controller module 200 is configured to generate a clockwise rotating alternating magnetic field RAMF starting from the drive wires. That is, the RF controller module 200 applies RF carrier signals S1-S12 sequentially to the first drive wire T1, the first sensing wire R1, the second drive wire T2, the second sensing wire R2, the third drive wire T3, the third sensing wire R3, the fourth drive wire T4, the fourth sensing wire R4, the fifth drive wire T5, the fifth sensing wire R5, the sixth drive wire T6, and the sixth sensing wire R6, starting from the first drive wire T1, so as to generate and transmit a clockwise rotating alternating magnetic field RAMF through the conductive grid 100 and simulate the RF antenna simulation unit 20.
[0096] The design disclosed in the first embodiment above can generate a rotating alternating magnetic field around the conductive grid 100 to form a radio frequency antenna simulation unit 20 to transmit wireless radio frequency carrier signals. The radio frequency antenna simulation unit 20 can preferably be used to simulate a near-field communication (NFC) antenna, a high-frequency / low-frequency radio frequency identification (HF / LF) antenna, a magnetically secure transmission (MST) antenna, a wireless power transmission antenna, or a wireless communication antenna. This allows the conductive grid 100, which was originally only used as a touch sensor for the touch panel, to be used simultaneously as an antenna unit for transmitting wireless radio frequency carrier signals. It also has the advantage of being able to use the touch panel grid for radio frequency communication without configuring an additional antenna or antenna module.
[0097] Figure 8 A schematic diagram of the structure of an antenna element simulated by implementing the second embodiment of the present invention is disclosed. In the second embodiment, the radio frequency controller module 200 is configured to generate a clockwise rotating alternating magnetic field starting from the induction wires. That is, the radio frequency controller module 200 applies radio frequency carrier signals S1-S12 sequentially to the first induction wire R1, the second drive wire T2, the second induction wire R2, the first drive wire T1, the third induction wire R3, the fourth drive wire T4, the fourth induction wire R4, the third drive wire T3, the fifth induction wire R5, the sixth drive wire T6, the sixth induction wire R6, and the fifth drive wire T5, so as to generate and transmit a clockwise rotating alternating magnetic field RAMF through the conductive grid 100 and simulate the radio frequency antenna simulation unit 20.
[0098] Figure 9 A schematic diagram of the structure of an antenna element simulated by implementing the third embodiment of the present invention is disclosed. In the third embodiment, the radio frequency controller module 200 is configured to generate a counterclockwise rotating alternating magnetic field starting from the drive wires. That is, the radio frequency controller module 200 applies radio frequency carrier signals S1-S12 sequentially to the first drive wire T1, the second sensing wire R2, the second drive wire T2, the first sensing wire R1, the third drive wire T3, the fourth sensing wire R4, the fourth drive wire T4, the third sensing wire R3, the fifth drive wire T5, the sixth sensing wire R6, the sixth drive wire T6, and the fifth sensing wire R5 through the conductive grid 100 to generate and transmit a counterclockwise rotating alternating magnetic field RAMF and simulate the radio frequency antenna simulation unit 20.
[0099] Figure 10This diagram illustrates the control principle of a fourth embodiment of the present invention. The fourth embodiment is based on and includes the first embodiment. Preferably, the fourth embodiment is a conductive grid radio frequency control method, particularly a simultaneous multiphase radio frequency control method. In the fourth embodiment, to enhance the strength of the radio frequency carrier signal emitted by the conductive grid 100, improve coupling efficiency, and expand the communication range, the radio frequency controller module 200 is configured to generate signals that have the same operating frequency and, for example, but not limited to, a phase difference between them. or The first synthesized radio frequency carrier signal C1, the second synthesized radio frequency carrier signal C2, the third synthesized radio frequency carrier signal C3, and the fourth synthesized radio frequency carrier signal C4 are applied simultaneously, for example, but not limited to, at t=0, through positions ①, ②, ③, and ④ respectively, to the first driving wire T1, the first sensing wire R1, the second driving wire T2, and the second sensing wire R2. At the next moment, for example, but not limited to, t=0.0001 seconds, t=0.001 seconds, t=0.01 seconds, p / 4 seconds, or t=p / 2 seconds, the same operation is continued, and this cycle is repeated continuously.
[0100] The applied first synthetic radio frequency carrier signal C1, second synthetic radio frequency carrier signal C2, third synthetic radio frequency carrier signal C3 and fourth synthetic radio frequency carrier signal C4 are all generated in accordance with the method for generating synthetic radio frequency carrier signal C described in the first embodiment, and all have an operating frequency f of 13.56MHz, and are radiated through the radio frequency antenna analog unit 20 formed by the first turn coil L1, the second turn coil L2 and the third turn coil L3 of the conductive grid 100.
[0101] Compared to the first embodiment, which uses a segmented in-phase radio frequency control method and transmits only one composite radio frequency carrier signal per transmission, the fourth embodiment uses a synchronous multiphase radio frequency control method and can transmit four composite radio frequency carrier signals per transmission. If the phase difference is further reduced, for example to [missing information], [missing information]. or The phase difference can also be further increased, for example, by increasing it to... Phase difference Preferably, it can also be, for example, but not limited to: or Similarly, each transmission can emit more synthetic radio frequency carrier signals, effectively enhancing the magnetic field strength of RAMF1-RAMF3 formed on and around the conductive grid 100. This allows for more effective utilization of the overall structure of the conductive grid 100 to radiate energy, thereby effectively enhancing the overall radio frequency signal strength emitted by the conductive grid 100, improving coupling efficiency, or expanding the effective communication range.
[0102] Figure 11 This invention discloses a schematic diagram of the control principle of a fifth embodiment. The fifth embodiment is based on and includes the first embodiment. The fifth embodiment is preferably a conductive grid radio frequency control method, particularly a multiphase time-interleaved radio frequency control method.

[0104] Figure 12 A schematic diagram of the system architecture of the radio frequency (RF) controller module included in this invention is disclosed. In one embodiment, the RF controller module 200 preferably includes multiple internal functional units to achieve RF control of the conductive grid 100. For example, the RF controller module 200 is configured to include a power management unit (PMU) 210, a control unit 220, an oscillator 230, a signal generation and phase control unit 240, and a power amplifier 250. The power management unit (PMU) 210 is configured to power other components, and the control unit (CON) 220 is preferably, for example, but not limited to, a microcontroller (MCU) or a field-programmable gate array (FPGA), configured to perform overall operating logic, timing control, mode management, and communication with external systems.
[0105] Preferably, the RF controller module 200 is further configured to include an oscillator 230, which is preferably, for example but not limited to, a quartz crystal oscillator XO or a temperature-compensated crystal oscillator TCXO, configured to provide a reference clock with a stable operating frequency f according to the instructions of the control unit 220; the RF controller module 200 is further configured to include a signal generation and phase control unit (SGPC) 240, which receives the reference clock and generates first to twelfth RF carrier signals S1-S12, etc., with a specified operating frequency and phase relationship according to the instructions of the control unit 220; the RF controller module 200 is further configured to include multiple power amplifiers (PA) 250 to amplify the first to twelfth RF carrier signals S1-S12 to give them sufficient transmit power and current to form first to third rotating alternating magnetic fields RAMF1-RAMF3.
[0106] Figure 13 This invention discloses a schematic diagram of the system architecture of the conductive mesh radio frequency control system included in this invention. The conductive mesh radio frequency control system 300 proposed in this invention includes a conductive mesh 100, a radio frequency controller module 200, a main control module 310, a switch 320, and a touch panel driver module 330.
[0107] The touch panel driver module 330 is preferably a conventional touch panel driver that uses the conductive grid 100 as a sensor grid or sensing array and performs conventional touch panel functions. The touch panel driver module 330 drives the driving wire layer 110 included in the conductive grid 100 to generate an induced electric field so as to generate mutual capacitance with the sensing wire layer 130, and detects the change in mutual capacitance value by scanning the entire sensing wire layer 130, thereby determining the touch point.
[0108] The switch 320 also includes multiple radio frequency switches and is controlled by the main control module 310 to selectively connect the first to ninth driving wires T1-T9 and the first to ninth sensing wires R1-R9 contained in the conductive mesh 100 to the touch panel driver module 330 or the radio frequency controller module 200, so that the conductive mesh 100 can switch between touch mode and antenna mode. When the conductive mesh 100 is electrically connected to the touch panel driver module 330, the conductive mesh 100 will enter touch mode; when the conductive mesh 100 is electrically connected to the radio frequency controller module 200, the conductive mesh 100 will enter antenna mode.
[0109] The main control module 310 can be configured to control the switching switch 320 to determine whether the conductive mesh 100 is electrically connected or disconnected from the radio frequency controller module 200 or the touch panel driver module 330, or to determine whether the conductive mesh 100 is electrically connected or disconnected from the radio frequency controller module 200 or the touch panel driver module 330 according to external instructions or specific application scenarios, so as to control the conductive mesh 100 to switch between touch mode and antenna mode.
[0110] Furthermore, to avoid mutual interference caused by simultaneous operation of touch mode and antenna mode, the main control module 310 is preferably configured to use time division multiplexing (TDM) technology. Within a very short time interval, it controls the conductive mesh 100 to alternate between electrical connection with the RF controller module 200 and electrical connection with the touch panel driver module 330. This controls the conductive mesh 100 to quickly alternate between performing touch sensing operations and RF electromagnetic field generation operations, and to clearly switch between touch mode and antenna mode. This enables the conductive mesh 100 to have dual functions of touch sensing and RF carrier signal transmission, and can be used as both a touch panel and an NFC / RFID antenna.
[0111] Figure 14 The present invention discloses a schematic diagram of the sensing area configuration after the conductive mesh radio frequency control system performs selective sensing area configuration on the touch panel included in the touch screen. Figure 15 This diagram illustrates the conductive grid radio frequency control system included in the present invention, configured in conjunction with a selective sensing area, to display corresponding indication information on a touch screen. In this embodiment, the conductive grid radio frequency control system 300 is preferably integrated with a touch display 400, which includes a touch panel 410 and a display area 420. The touch panel 410 is preferably configured within the area including the display area 420.
[0112] like Figure 14 As disclosed, the touch panel 410 is formed by a conductive grid 100 consisting of multiple orthogonally arranged driving electrodes Tx and sensing electrodes Rx as a touch sensor grid. The radio frequency controller module 200 is configured to select, for example but not limited to, the first sensing area A1, the second sensing area A2 and the third sensing area A3 included in the conductive grid 100 as antenna sensing areas according to the user's selection settings or the system's preset values.
[0113] Preferably, the RF controller module 200 is configured to define the range of the first sensing region A1 as the antenna sensing region, and implements a conductive grid RF control method on the driving electrodes Tx_n to Tx_m and sensing electrodes Rx_n to Rx_m included in the first sensing region A1, so as to form a first RF antenna simulation unit 21 on the conductive grid 100 corresponding to the range of the first sensing region A1, as an example, but not limited to, an NFC antenna.
[0114] Preferably, the RF controller module 200 is configured to define the range of the second sensing region A2 as the antenna sensing region, and implements a conductive grid RF control method on the driving electrodes Tx_i to Tx_j and sensing electrodes Rx_n to Rx_m included in the second sensing region A2, so as to form a second RF antenna simulation unit 22 on the conductive grid 100 corresponding to the range of the second sensing region A2, as, for example, but not limited to, an LF RFID antenna.
[0115] Preferably, the RF controller module 200 is configured to define the range of the third sensing region A3 as the antenna sensing region, and implements a conductive grid RF control method on the driving electrodes Tx_i to Tx_j and sensing electrodes Rx_i to Rx_j included in the third sensing region A3, so as to form a third RF antenna simulation unit 23 on the conductive grid 100 corresponding to the range of the third sensing region A3, as, for example, but not limited to, an HF RFID antenna.
[0116] like Figure 15 As disclosed, after the RF controller module 200 successfully simulates the first RF antenna simulation unit 23, the second RF antenna simulation unit 23, and the third RF antenna simulation unit 23 on the conductive grid 100, the main control module 310 or the RF controller module 200 is configured to display indication information in the display area 420 of the touch display 400 corresponding to the first sensing area A1, the second sensing area A2, and the third sensing area A3. The indication information is preferably, but not limited to, patterns, icons, visual cues, text, arrows, bright spots, luminous blocks, illustrations, or text prompts, so as to clearly indicate to the user the specific locations of the first RF antenna simulation unit 23, the second RF antenna simulation unit 23, and the third RF antenna simulation unit 23.
[0117] For example, the main control module 310 or the radio frequency controller module 200 can be configured to display the instruction text "NFC please sense", "RFID tag please sense", and "RFID card please sense" in color blocks in the display area 420 corresponding to the first sensing area A1, the second sensing area A2, and the third sensing area A3, respectively, so as to clearly indicate to the user the sensing position of the NFC card, RFID tag, and RFID card, and clearly guide the consumer to bring the NFC / RFID target device close to the correct position.
[0118] Figure 16 A flowchart illustrating the implementation steps of the conductive grid radio frequency control method included in this invention is provided. The conductive grid radio frequency control method 500 of this invention preferably includes, but is not limited to, the following steps: providing a conductive grid comprising a plurality of driving wires and a plurality of sensing wires arranged in an intersecting manner (step 501); selecting a first driving wire, a second driving wire, a first sensing wire, and a second sensing wire from the driving wires and the sensing wires (step 502); generating a first radio frequency carrier signal, a second radio frequency carrier signal, a third radio frequency carrier signal, and a fourth radio frequency carrier signal having the operating frequency, the first radio frequency carrier signal, the second radio frequency carrier signal, the third radio frequency carrier signal, and the fourth radio frequency carrier signal having the same phase with each other (step 503); and sequentially applying the first radio frequency carrier signal, the second radio frequency carrier signal, the first sensing wire, and the second sensing wire to the first driving wire, the second driving wire, the first sensing wire, and the second sensing wire, respectively (step 504).
[0119] The conductive grid radio frequency control module, system, and method proposed in this invention can be applied not only to analog NFC antennas but also to other near-field wireless communication technologies that utilize radio frequency carrier principles, such as, but not limited to, RFID antennas in RFID initiating devices. This invention can also be applied to HF RFID antennas in initiating devices that read high-frequency radio frequency identification (HF RFID) conforming to relevant standards such as, but not limited to, ISO / IEC 14443A / B, ISO / IEC 18092, and ISO / IEC 15693, making it suitable for various application scenarios such as smart card reading, access control, logistics tracking, and electronic ticketing.
[0120] This invention is preferably applied to point-of-sale (POS) terminals, kiosks, checkout (SCO) terminals, all-in-one PCs with integrated touch functionality, automatic ticket vending machines, or access control terminals. Traditional POS terminals, SCO terminals, or kiosks typically include a touchscreen for the user interface and a separate NFC / RFID reader module for payment or identification. The conductive grid RFID control module, system, and method proposed in this invention directly integrate NFC / RFID sensing functionality into the touchscreen itself, particularly into the front display area. Users simply need to bring their NFC-enabled payment card, smartphone, or RFID ID card close to or lightly touch the touchscreen surface to complete checkout, membership identification, ticket verification, and other operations, without needing to find or align it with a specific sensing area outside the screen. This greatly enhances the intuitiveness and convenience of use, and significantly improves the smoothness and intuitiveness of the user experience.
[0121] The conductive grid radio frequency control module, system, and method proposed in this invention also include the following features:
[0122] (1) High functional integration: The conductive mesh of the touch panel is cleverly reused, enabling the touch screen to have both touch sensing and RF antenna functions such as NFC or RFID antennas, reducing the number of components.
[0123] (2) Significantly saves space: There is no need to reserve installation space for a separate NFC / RFID antenna module, which is especially beneficial for mobile devices, POS machines and other devices with limited internal space, and helps to achieve a thinner and more compact product design.
[0124] (3) Reduce potential costs: Save on material costs required for configuring NFC / RFID antenna modules, as well as related FPC connection, assembly and testing costs.
[0125] (4) Simplified design and assembly: Reduces the number of RF components that require layout and routing, simplifying the design and manufacturing assembly process.
[0126] (5) Enhance user experience: Especially in applications such as POS, SCO, and Kiosk, the intuitive operation of "screen as sensing area" has been realized, which has improved the convenience and smoothness of interaction.
[0127] (6) Design flexibility: It brings more possibilities to the industrial design of products, such as the possibility of achieving a completely flat, hole-free front of the device.
