Description

Technical Field

[0001] The utility model mainly relates to the technical field of short-distance communication, and in particular to a display with dual NFC function modules. Background Art

[0002] In the use scenario of commercial cash registers, there are two main ways to implement the NFC (Near Field Communication) card swiping function: one is to use external accessories to swipe the card, and the other is to embed an NFC function module (including the NFC antenna under the screen) behind the display screen and make the NFC antenna position correspond to the card swiping display screen area. When turning on the NFC function or using NFC-related apps, the software interface is set with an "NFC card swiping area" prompt to facilitate human-machine operation.

[0003] Many single-screen displays support screen (display) flipping, for example, in cash register usage scenarios, the interface can be changed from clerk-facing to customer-facing, making interaction easier. At the same time, because screen flipping will cause the display to be upside down, the display interface will be adjusted accordingly based on the sensor information embedded in the screen. When the display is detected to be flipped, the screen display content will be rotated 180 degrees by default to ensure that the display content is displayed consistently in the up, down, left, and right directions of the clerk and customer sides.

[0004] At present, there is only one NFC function module embedded in a single-screen display device, and the NFC function module is not located in the center area of ​​the screen. When the device is used in a flip scenario, especially when the NFC function is turned on or NFC-related APPs are used, the "NFC card swiping area" displayed after the display interface is directly rotated 180 degrees and the actual NFC physical antenna area are misaligned, and the NFC function cannot be used correctly.

[0005] In the prior art, an NFC function module and dual NFC sensing antennas are designed under the display screen. The NFC sensing antennas are generally connected to the NFC function module in two ways: the dual antennas are directly connected in parallel or in series and then directly connected to the antenna end of the NFC function module. This method will cause partial attenuation of the antenna coil performance, affecting the difficulty of antenna debugging and the normal use of the NFC function. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a display with dual NFC function modules, which can ensure that the actual card reading area of ​​the NFC function corresponds to the NFC card swiping prompt area on the human-computer interaction interface of the display screen, thereby stably using the NFC function of the display.

[0007] To solve the above technical problems, the utility model provides a display with dual NFC function modules, the display state of the display includes a first display state before flipping and a second display state after flipping, including: a first NFC function module, the first NFC function module is built in a card reading area on one side of the display; a second NFC function module, the second NFC function module is built in the card reading area on the other side of the display; a sensing module, the sensing module is used to sense the current display state of the display and output a sensing signal, the sensing signal includes the first sensing signal before the display is flipped and the second sensing signal after the flipping; a switching module, the switching module is used to enable the corresponding NFC function module according to the sensing signal of the sensing module; wherein when the switching module receives the first sensing signal, the first NFC function module is enabled, and when the switching module receives the second sensing signal, the second NFC function module is enabled.

[0008] Optionally, the first NFC functional module and the second NFC functional module are axially symmetrically arranged on the display.

[0009] Optionally, the sensing module adopts a three-axis gravity sensor.

[0010] Optionally, the sensing module adopts an angle sensor.

[0011] Optionally, the angle sensor is used to output a first perception signal when the rotation angle of the display is less than a set threshold, and output a second perception signal otherwise.

[0012] Optionally, the set threshold is greater than 45°.

[0013] Optionally, a control module is further included, and the control module is used to turn on and off the switching function of the switching module.

[0014] Optionally, the control module is used to enable the switching function of the switching module when the display calls the NFC function module, and to disable the switching function of the switching module when the display does not call the NFC function module.

[0015] Optionally, the switching module is a switching switch, which is used to enable the first NFC function module before switching and enable the second NFC function module after switching.

[0016] The utility model also provides another display with dual NFC function modules, including: a first NFC function module, which is built into a card reading area on one side of the display; a second NFC function module, which is built into the card reading area on the other side of the display, and the first NFC function module and the second NFC function module are in an enabled state at the same time.

[0017] Compared with the prior art, the utility model has the following advantages: because the display has two independent NFC function modules, and the enabled NFC function module can adapt to the current display state of the display, no matter what display state or usage scenario the display is in, it can ensure that the actual card reading area of ​​the NFC function and the NFC card swiping prompt area on the human-computer interaction interface of the display screen correspond to each other, thereby stably using the NFC function of the display.

[0030] Figure 1 Schematic diagram of the display flipping process in one embodiment of the present invention, refer to Figure 1 As shown, due to usage needs, the display 100 sometimes needs to face the clerk, and sometimes needs to face the customer. This type of display 100 generally has a corresponding support structure, and is flipped with the support structure as a support point, thereby meeting the needs of the display 100 facing the clerk or facing the customer, that is, the display 100 changes from the display state P1 to the display state P2, referring to Figure 2 In the original display state P1, the position of the first NFC function module 102 is exactly the NFC card swiping area of ​​the UI interface, and the NFC function can be used normally when swiping the card; when the display state of the display 100 changes to the display state P2, the display interface (including content and structure) seen by the customer needs to be the same as the display interface seen by the clerk, such as Figure 2As shown in the figure, the left side is the APP application display content area, and the right side is the NFC card swiping prompt area. Therefore, the UI interface on the display 100 will rotate 180°, but the actual position of the first NFC function module 102 on the display 100 will not change due to the rotation of the UI interface. At this time, the NFC card swiping prompt area and the actual area where the first NFC function module 102 is located will be misaligned, and the normal use of the NFC function cannot be guaranteed.

[0031] refer to Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a display 100 with dual NFC function modules, wherein the display state of the display 100 includes a first display state before flipping and a second display state after flipping, and its structure mainly includes: a first NFC function module 102, built in a card reading area on one side of the display 100; a second NFC function module 103, built in a card reading area on the other side of the display 100; a sensing module 104, used to sense the current display state of the display 100 and output a sensing signal, wherein the sensing signal includes a first sensing signal before the display 100 is flipped and a second sensing signal after the flipping; a switching module 105, used to enable the corresponding NFC function module according to the sensing signal of the sensing module 104; wherein when the switching module 105 receives the first sensing signal, the first NFC function module 102 is enabled, and when the switching module 105 receives the second sensing signal, the second NFC function module 103 is enabled. Figure 3 In order to distinguish the two NFC functional modules, the first NFC functional module 102 is represented by a solid line, and the second NFC functional module 103 is represented by a dotted line.

[0032] In order to ensure the normal use of the NFC function, in this embodiment, the display 100 is provided with a first NFC function module 102 and a second NFC function module 103. Specifically, in this embodiment, the display 100 senses the current display state of the display 100 (display state P1 or display state P2) through the sensing module 104, and sends the sensing signal corresponding to the current display state to the switching module 105. Then, the switching module 105 enables the corresponding NFC function module according to the received sensing signal. For example, when the switching module 105 receives the first sensing signal, the first NFC function module 102 is enabled, and when the switching module 105 receives the second sensing signal, the second NFC function module 103 is enabled, thereby ensuring that no matter what display state the display 100 is in, the NFC card swiping area in the current UI interface corresponds to the position of the enabled NFC function module, and the NFC function of the display 100 will not be unusable due to the flipping of the display 100.

[0033] Figure 5This is a schematic diagram of the effect of the display of an embodiment of the utility model, referring to Figure 5 As shown, before the display 100 is flipped, if the display 100 is on the clerk side, the NFC card swiping area of ​​the UI interface is on the right side of the display screen 101. At this time, the first NFC function module 102 is in an enabled state, and the NFC function is played, while the second NFC function module 103 is in a disabled state. Generally speaking, the NFC function of the display 100 is not affected. When the display 100 is flipped, the display 100 is on the customer side, and the NFC card swiping area of ​​the UI interface is on the right side of the current display screen 101. At this time, the second NFC function module 103 is in an enabled state, and the NFC function is played, while the first NFC function module 102 is in a disabled state. Generally speaking, the NFC function of the display 100 is still not affected. It can be seen that no matter what display state the display 100 is in, its NFC function can be used normally.

[0034] In one example, the first NFC function module 102 and the second NFC function module 103 are axially symmetrically arranged on the display 100. Figure 3 As shown in the figure, the first NFC functional module 102 is located on the left side of the display screen 101, and the second NFC functional module 103 is located on the right side of the display screen 101. A1 is the axis of symmetry, and the first NFC functional module 102 and the second NFC functional module 103 are symmetrically arranged with A1 as the axis. Generally, the axis A1 is also an axis of symmetry of the display screen 101.

[0035] In one example, the sensing module 104 may use a three-axis gravity sensor.

[0036] A three-axis gravity sensor is a sensor that can measure the gravitational acceleration of an object relative to the surface of the earth. Exemplarily, the three-axis gravity sensor can be composed of an accelerometer and a gyroscope, and a mathematical algorithm is used to combine the information of the two. By combining the information of the accelerometer and the gyroscope, the gravitational acceleration and rotation information of the object relative to the surface of the earth can be obtained. This information can be used for various applications, such as detecting the direction of the device in a mobile device, performing motion tracking and control, etc. In this embodiment, the three-axis gravity sensor has a spatial x, y, x three-axis coordinate reference, and the orientation change of the display 100 can be easily identified by transforming the three-axis coordinate data.

[0037] In this embodiment, two independent and complete NFC function modules (including corresponding sensing antennas) are symmetrically designed in the area behind the display screen 101 of the display 100. The display state of the display 100 is sensed by a three-axis gravity sensor, and the correct NFC function module is enabled accordingly to ensure that the NFC function and the software display interface can be used normally before and after flipping. For example, when the display screen 101 faces the clerk, the second NFC function module 103 is turned off by default, the first NFC function module 102 is turned on, and the card swiping prompt area is displayed on the right side of the current display interface; when the display screen 101 faces the customer, the first NFC function module 102 is turned off by default, the second NFC function module 103 is turned on, and the card swiping prompt area is displayed on the right side of the current display interface.

[0038] In one example, the sensing module 104 uses an angle sensor.

[0039] The angle sensor is based on the effect of rotational transformation. When the angle sensor is connected to the display 100, as the display 100 flips (rotates, turns), the angle sensor generates a changing signal, which is converted into a digital signal, processed and analyzed by a processor, and finally the accuracy and direction of the rotation of the display 100 are obtained. The more common angle sensors include rotation angle sensors, magnetic angle sensors and optical angle sensors. The rotation angle sensor is suitable for high-precision angle measurement and can measure rotation angles of more than 60°. The magnetic angle sensor can measure the rotation angle of an object relative to a magnetic field by connecting the sensor to a magnetic material. The optical angle sensor uses optical principles to measure the angle by measuring the changes in the light signal received by the photoelectric sensor.

[0040] In one example, the angle sensor is used to output a first sensing signal when the rotation angle of the display 100 is less than a set threshold, and output a second sensing signal otherwise. That is, it is necessary to ensure that the rotation of the display 100 is effective, and the rotation of the display 100 is to complete the effective rotation of the flip function of the display 100, rather than invalid rotation caused by other erroneous operations. Furthermore, the set threshold is greater than 45°.

[0041] refer to Figure 1 As shown, taking the display 100 applied to the clerk side as an example, if the horizontal plane is L1 and the plane where the display 100 is located is L2, then the angle between the display 100 and the horizontal plane is β, and the angle β is generally 45° to 60°. Therefore, as long as the rotation angle of the display 100 is less than 45°, it means that the display 100 has not been rotated to the customer side, and it can be considered that the rotation is not a flip of the display 100, and there is no need to switch the enabled state of the NFC function module. Only when the rotation angle is greater than 45° (at least greater than 45°), it means that the display 100 is flipped to the customer side, and the enabled state of the NFC function module needs to be switched to meet the NFC function usage requirements.

[0042] In one example, a control module 106 is further included, which is used to turn on and off the switching function of the switching module 105. Further, the control module 106 is used to turn on the switching function of the switching module 105 when the display 100 calls the NFC function module, and turn off the switching function of the switching module 105 when the display 100 does not call the NFC function module.

[0043] For example, the purpose of the display 100 having two NFC function modules in this embodiment is that when the display 100 is in different display states after being flipped, the NFC function of the display 100 can be used normally. However, in actual application scenarios, the display 100 does not need to enable the NFC function in real time, and the NFC function is enabled only when needed, such as when NFC payment is required. Therefore, in order to save energy consumption, the control module 106 can be set to enable the switching function of the switching module 105 only when the display 100 calls the NFC function module.

[0044] In one example, the switching module 105 can be a switching switch (or a transfer switch), which enables the first NFC function module 102 before switching and enables the second NFC function module 103 after switching. A transfer switch is a low-voltage switch for switching multiple circuits, with multiple moving contacts welded on its shaft. When the shaft rotates, the moving contacts are connected or disconnected with the static contacts in turn, switching the circuit from one set of connections to another set of connected electrical appliances. In this embodiment, the transfer switch can be used to switch the activation of the first NFC function module 102 to the activation of the second NFC function module 103, or to switch the activation of the second NFC function module 103 to the activation of the first NFC function module 102.

[0045] The display with dual NFC function modules provided in this embodiment can ensure that the actual card reading area of ​​the NFC function corresponds to the NFC card swiping prompt area on the human-computer interaction interface of the display screen, regardless of the display state or usage scenario, thereby stably using the NFC function of the display.

[0046] Another embodiment of the present invention provides a display with dual NFC function modules, the structure of the display 100 mainly includes: a first NFC function module 102, which is built into the card reading area on one side of the display 100; a second NFC function module 103, which is built into the card reading area on the other side of the display 100, and the first NFC function module 102 and the second NFC function module 103 are simultaneously in an enabled state. This structure in which two NFC function modules are enabled simultaneously can avoid setting an enabling conversion structure for the first NFC function module 102 and the second NFC function module 103, and the performance is more stable, but this structure also has shortcomings, mainly reflected in that the first NFC function module 102 and the second NFC function module 103 are both in an enabled state, which is bound to increase more energy consumption.
