Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a flexible transparent in-screen antenna for communication and millimeter-wave radar sensing and a setting method thereof. Background Art

[0002] With the development of communication technologies and the popularization of wireless local area networks, the number of network-connected devices with display screens in households, such as televisions, personal computers, mobile phones, etc., is increasing continuously, and their functions are constantly enhanced. These display screens supported by new communication technologies are no longer just multimedia playback terminals, but are extending towards multiple functions such as gaming and shopping. Therefore, the demand for display screen control has, on the basis of remote control button control, touch screen control, external peripheral keyboard and mouse control, etc., given rise to various control requirements that do not require contact, such as eye tracking, gesture recognition, voice recognition, etc. The realization of these control requirements requires a high-performance sensing system and a reasonable design of the system structure.

[0003] The next-generation 5G mobile communication system will use electromagnetic waves in the millimeter-wave band for communication, and various household intelligent devices also need to conform to the development of communication technologies. The proposal of the Internet of Things concept has put forward new requirements for the design of the communication systems of intelligent home appliances. Therefore, it is necessary to take into account both sensing and communication aspects in the design of intelligent home appliances, and reasonably design the antenna array to ensure the stability of functional modules.

[0004] With the continuous development of smart phones, screen designs that expand the screen area of mobile phones, such as full-screen and foldable screens, will gradually become mainstream. However, since the millimeter-wave antennas required in the next-generation communication technologies can no longer be installed on the mobile phone backplane with high losses, there is a conflict between installing the antenna on the front of the mobile phone and expanding the mobile phone screen area. Therefore, using a flexible transparent antenna is a feasible solution to the conflict between millimeter-wave communication and the functions of full-screen and foldable screens.

[0005] Currently, the miniaturization and foldability of intelligent devices are gradually becoming a trend. Not only mobile phones, but also display devices such as household televisions are moving towards a development path of being thin, light, and flexible. This demand makes it necessary for traditional home appliances such as televisions to have antennas that match them to achieve communication functions when applying flexible screens. Therefore, the importance of antenna designs that can simultaneously match millimeter-wave communication and flexible screens is increasing. Summary of the Invention

[0039] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0040] The flexible transparent screen-integrated antenna for communication and millimeter-wave radar sensing proposed according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] Figure 1 A microscopic schematic diagram of the antenna design according to an embodiment of the present invention.

[0042] As Figure 1 shown, the flexible transparent screen-integrated antenna for communication and millimeter-wave radar sensing is fabricated on a metal grid formed by the periodic arrangement of basic units of a polygon.

[0043] In the embodiment of the present invention, a hexagon is taken as an example for introduction. Further, the polygon can be a hexagon, a rectangle, a rhombus, a triangle, etc. The embodiments of the present invention do not make specific limitations, and polygons of other shapes can also be used as the implementation manners of the present invention.

[0044] AsFigure 1 As shown, the antenna adopts a metal mesh structure. The transparent performance is achieved through the periodic arrangement of hexagonal basic units. At the same time, the periodic mesh structure of hexagons can provide stronger stress resistance. While ensuring the flexibility of the antenna, when stressed, compared with basic unit structures such as quadrilaterals, the changes in characteristics such as the resonance frequency of the antenna are smaller.

[0045] Based on the metal mesh composed of hexagonal basic units, antennas and antenna arrays with structures including but not limited to flexible and transparent slot antennas, patch antennas, etc. can be fabricated, and the performance such as the operating frequency and coverage area of the antenna can be adjusted by patterning the metal mesh.

[0046] In the fabrication of the antenna, metals including but not limited to silver, copper, nickel, etc. can be used as conductive materials. Specific fabrication methods include but not limited to etching after electroplating, etching after magnetron sputtering, etc.

[0047] Figure 2 It is a microscopic schematic diagram of the edge of a patch antenna designed for the antenna according to an embodiment of the present invention.

[0048] Reference Figure 2 , when performing the patterning fabrication of the antenna, try to keep the pattern edges in good periodicity, such as the two edge patterns shown in Figure 2 . The periodic metal mesh with better edge periodicity has higher transparency.

[0049] When fabricating an antenna with a more complex pattern, the metal mesh can also be directly cut or etched to obtain edges with poor periodicity. Since the antenna size is much larger than the size of the hexagonal basic unit, the finally obtained antenna can still maintain good transparency and other performances.

[0050] When installing the antenna in the present invention inside the screen, the antenna with a transparent dielectric layer pad needs to be installed above the substrate (such as glass) through a transparent adhesive to effectively isolate the antenna from the display circuit and touch circuit below. At the same time, a periodic metal mesh pattern can be added to the screen area without antenna distribution to achieve higher transparency of the antenna.

[0051] Such as Figure 3 shown, the in-screen antenna is installed under the screen protection layer, and electromagnetic isolation from other metal traces below is achieved through the dielectric layer, and bonding is achieved through the adhesive. The touch traces and light-emitting unit layer in the screen are both located below the in-screen antenna.

[0052] The flexible transparent in-screen antenna for communication and millimeter-wave radar sensing proposed according to an embodiment of the present invention adopts a metal mesh structure, realizes the transparent performance through the periodic arrangement of basic polygon units, and at the same time, the periodic mesh structure of the polygon can provide stronger stress resistance. While ensuring the flexibility of the antenna, compared with basic unit structures such as quadrilaterals, the changes in characteristics such as the resonance frequency of the antenna are smaller under stress.

[0053] Figure 4 A setting method for the flexible transparent in-screen antenna for communication and millimeter-wave radar sensing according to an embodiment of the present invention.

[0054] As Figure 4 shown, for the setting method of the flexible transparent in-screen antenna for communication and millimeter-wave radar sensing, the flexible transparent in-screen antenna includes a radar antenna and a communication antenna, and includes:

[0055] S1, simultaneously set the radar antenna and the communication antenna in the display screen;

[0056] S2, the radar antenna is distributed at the central position of the display screen, and the communication antenna is located at the edge position of the display screen.

[0057] When the antenna in the present invention is installed in the display screen and the communication and radar sensing functions are simultaneously realized, it is arranged in such a way that the radar antenna is distributed at the central position and the communication antenna is distributed at the edge position. The arrangement method refers to Figure 5 , and the following given embodiments all realize the application of the antenna in the present invention according to this proposed arrangement method.

[0058] Figure 6 is a working schematic diagram of an embodiment realized according to the arrangement method proposed by the present invention. It can be seen that this arrangement method reduces the interference between the millimeter-wave radar antenna and the millimeter-wave communication antenna from the spatial position. And for different usage situations of users, good simultaneous operation of communication and radar sensing can be achieved through beam control of the antenna.

[0059] Figure 7 An embodiment of applying the antenna according to an embodiment of the present invention to a mobile phone screen.

[0060] Refer to Figure 7 , the millimeter-wave antenna in the present invention can be installed at the top and bottom of the mobile phone screen, including but not limited to the positions 301a, 301b, 302, 303a, 303b shown in the figure. The transparency of the antenna results in only a small occlusion of the content displayed on the screen below. This part of the occlusion can be compensated by increasing the screen brightness of the antenna installation part, or by adding repeated metal mesh patterns in other parts of the screen without antenna distribution to improve the overall transparency consistency.

[0061] The 301a and 301b millimeter-wave antennas are installed on both sides of the top of the mobile phone screen to achieve the high-speed short-range communication function of the mobile phone. The installation position on the top side can avoid the absorption of millimeter-wave signals by the human body.

[0062] The 302 millimeter-wave antenna is installed on the upper edge of the mobile phone screen. The millimeter-wave antenna at this position can be used as a millimeter-wave radar to achieve functions such as line-of-sight tracking and gesture recognition. At the same time, the front camera module of the mobile phone can also be installed together at this position to save space on the screen.

[0063] The 303a and 303b millimeter-wave antennas are installed in the lower half of the mobile phone screen for millimeter-wave communication during calls. When the user uses the mobile phone for a call, the user's head will block the antennas at the top of the screen. The antennas in the lower half of the mobile phone screen can ensure normal signal transmission with low absorption rate.

[0064] The 301a, 301b, 303a, and 303b millimeter-wave antennas are symmetrically distributed along the central axis of the mobile phone. When the user uses the mobile phone in landscape mode, the symmetrically distributed antennas can select the side with less transmission loss for communication, reducing the absorption of millimeter-wave signals by the user's hand when using the mobile phone in landscape mode.

[0065] Figure 8 It is a specific illustration diagram of the antenna applied to the bottom of the mobile phone according to an embodiment of the present invention.

[0066] Reference Figure 8 , the millimeter-wave antennas applied to the bottom of the mobile phone screen in the present invention are shown as 401a and 401b. The 402 in the figure is modules such as the microphone and wired communication interface at the bottom of the mobile phone.

[0067] The main coverage range of the 401a and 401b antennas is in the hemispherical direction perpendicular to the mobile phone screen. This transmission direction can make the signal transmission and reception of the antennas less interfered by other modules installed at the bottom of the mobile phone screen. At the same time, the feeding network of the antennas is distributed on the upper layer of the signal transmission network of other modules, achieving less receiving interference.

[0068] Figure 9 It is an application example of the antenna applied to a foldable flat display device according to an embodiment of the present invention.

[0069] Reference Figure 9 , the foldable flat display device can be folded along the central axis shown in the figure. The antennas in the present invention can be applied to the screen edge areas similar to 501a, 501b, 501c, and 501d, or the screen center areas similar to 502a, 502b, and 502c.

[0070] Millimeter wave antennas in the edge areas of the screens similar to 501a, 501b, 501c, and 501d can be used for millimeter wave communication of flat panel display devices. The four-corner symmetrical distribution structure allows flat panel display devices to have antennas with low transmission loss to achieve normal communication functions under different holding or placement conditions.

[0071] The millimeter wave antenna in the center area of the screen similar to 502a, 502b, and 502c can be used for millimeter wave radar sensing. The multi-position distribution can realize radar sensing in different directions, thereby realizing multiple functions such as motion monitoring, gesture recognition, and auxiliary voice recognition. At the same time, the millimeter wave antenna in the center area of the screen can also realize wireless communication functions with other external devices, such as external mice, keyboards, handles, remote controls, etc.

[0072] On flat display devices with more sensing and communication functions, the distribution of antennas in the screen is relatively dense. The metal mesh antenna in the present invention is flexible enough and can be installed in a position similar to 502a in the screen above the rotating shaft, thereby ensuring the realization of dense distribution of antennas in the screen. Therefore, the antenna in the present invention can be widely and densely used in flexible or non-flexible screens. At the same time, the interference between densely distributed antennas can be solved by designing antennas working in different frequency bands and designing different functions in time.

[0073] Figure 10 This is another embodiment in which the antenna according to one embodiment of the present invention is applied to a foldable flat-panel display device.

[0074] refer to Figure 10 For smaller foldable display devices, such as foldable mobile phones and smaller foldable tablets, there is a design in which screens are distributed on both the inner and outer sides of the folding surface. In this embodiment, the millimeter wave antennas distributed only on the inner side cannot perform low-loss normal communication when the outer screen is used after folding, so it is necessary to add millimeter wave antennas to both the inner and outer screens. In the figure, 601a is the millimeter wave antenna in the outer screen, and 602b is the millimeter wave antenna in the inner screen.

[0075] Figure 10 The antenna distribution position shown in the figure is only used to indicate that the antenna is distributed both inside and outside, and does not mean that the antenna is specifically distributed in the center of the screen. Depending on the function of the antenna, the antenna can be distributed at different positions on the inside and outside of the screen. The overall Figure 9 Distribution shown with communication antennas at the edges and radar sensor antennas at the center.

[0076] When the foldable device is folded, communication or radar sensing can be performed through the millimeter-wave antenna on the outer side as shown in 601a. When the foldable device is unfolded, depending on the holding posture, communication can be selected through the communication antenna on the outer side or the inner side as shown in 601b, and at the same time, the radar sensing function is realized through the antennas distributed on the inner side.

[0077] Figure 11 It is a schematic diagram of the distribution position of the antenna according to an embodiment of the present invention specifically applied to a laptop computer.

[0078] Reference Figure 11 , the antenna in the present invention can also be applied to large screens such as laptop computer displays, desktop computer displays, and TV displays. In the figure, 701a and 701b are millimeter-wave antennas for communication distributed at the edge of the screen, and 702a, 702b, and 702c are millimeter-wave radar antennas for various different motion monitoring functions distributed in the off-center part of the screen.

[0079] Reference Figure 11 , the millimeter-wave radar distributed at the 702a position above the screen monitors the motion information of the user's head and face, and can realize the eye movement detection function. The millimeter-wave radar distributed at the 702b position in the center of the screen monitors the large-scale motion information of the human body directly in front of the screen, and can realize functions such as gesture recognition and user usage state detection. The millimeter-wave radar distributed at the 702c position below the screen detects the motion information of the user's throat and chest, and can realize the auxiliary speech recognition function.

[0080] Reference Figure 11 , the 702a, 702b, and 702c millimeter-wave radars adopt different operating frequencies according to the different amplitudes of the monitored motion information. Among them, 702a and 702c monitor smaller amplitudes of motion, and 702b monitors a larger amplitude of motion, which can achieve better frequency division and spatial working.

[0081] The antenna in the present invention is applied to the field of motion sensing, and the information obtained is the motion data of obstacles that absorb millimeter waves such as the human body. Compared with motion sensing by an optical camera, there is no need to obtain additional video information, the monitoring and recognition accuracy is high, and the risk of data leakage is smaller, and the security is strong.

[0082] Figure 12 It is a schematic diagram of the working principle of the radar antenna according to an embodiment of the present invention specifically applied to a laptop computer.

[0083] Reference Figure 12When a user uses a laptop, radar antennas at different positions inside the screen can implement various functions such as eye movement monitoring, throat vibration monitoring, and gesture recognition. At the same time, since the change in the user's position relative to the antennas inside the screen will cause a large change in the accuracy of small-amplitude motion sensing, before small-amplitude motion sensing, it is necessary to first perform large-amplitude motion sensing to detect the user's sitting posture, so as to more accurately implement radar motion sensing.

[0084] Figure 13 It is a working schematic diagram of an antenna according to an embodiment of the present invention applied to a large display device such as a TV.

[0085] Reference Figure 13 , communication antennas and radar antennas with different functions are respectively distributed at the edge and the center of the TV, realizing radar sensing of the user's movement and communication with wireless control devices and communication terminals.

[0086] In the present invention, the TV that performs wireless control through the antennas inside the screen directly communicates with the wireless control device. Compared with traditional Internet TVs, it reduces the pressure of internal network communication, and the wireless control device does not have to be connected to the network, which can cope with more diverse usage scenarios. At the same time, the use of millimeter waves instead of infrared remote control can be compatible with more diverse wireless control devices, and it is easier to find a compatible control device for control in the case of loss of the main control device.

[0087] In the present invention, the millimeter-wave radar antennas inside the screen are used to sense the movement of the user, so as to realize functions such as gesture recognition control and usage state detection. The motion sensing using the antennas inside the screen can save the total area of the TV, and there is no privacy and security problem compared with optical detection sensing.

[0088] Figure 14 It is a schematic diagram of an embodiment of an antenna according to an embodiment of the present invention applied to the front windshield of a car.

[0089] Reference Figure 14 , the arrangement of multiple antennas on the front windshield of the car can still adopt the form of edge distribution of communication antennas and center distribution of radar antennas. The requirements for the car to access Internet of Things communication, intelligent driving, etc. require the installation of a large-coverage sensing radar and millimeter-wave communication antennas on the car. Since the car body is mainly composed of metal and has a strong absorption of millimeter-wave signals, installing the millimeter-wave communication antennas on the windshield can reduce transmission loss.

[0090] Reference Figure 14, the in - windshield communication antenna installed on the inner side of the windshield can be distributed at the corners of the glass, thus further reducing the impact on the driver's line of sight. The specific installation method can also adopt the method of bonding with transparent adhesive, and an insulating and waterproof coating is applied outside the antenna to protect the antenna. Compared with the traditional antenna printed inside the glass, the antenna in the present invention does not block the line of sight and can be installed on the front and rear windshields, and the transmission loss can be reduced in a variety of transmission directions.

[0091] Meanwhile, the metal mesh antenna structure in the present invention can be used to make millimeter - wave identification tags, which are pasted on the glass edge to replace the traditional paper - mounted vehicle annual inspection and insurance signs, etc. The millimeter - wave identification tag has a higher transparency than the traditional sign and has less impact on the driver's line of sight. Moreover, by binding the millimeter - wave identification tag with vehicle information, forgery can be further prevented.

[0092] Figure 15 It is a schematic diagram of the principle of communication of the transparent metal mesh antenna in the windshield in an intelligent vehicle.

[0093] Reference Figure 15 , the millimeter - wave antenna in the windshield can communicate with devices such as nearby vehicles, fixed base stations on the roadside or at high places, and networked cameras at intersections. The antennas or antenna arrays on the front and rear windshields can receive different data by frequency division, so as to realize the synchronous multi - directional communication function.

[0094] It should be noted that the foregoing explanation of the antenna embodiment also applies to the setting method of this embodiment, and will not be elaborated here.

[0095] According to the setting method of the flexible transparent in - windshield antenna for communication and millimeter - wave radar sensing proposed in the embodiment of the present invention, the interference between the millimeter - wave radar antenna and the millimeter - wave communication antenna is reduced in terms of spatial position, and for different usage situations of users, good simultaneous operation of communication and radar sensing can be achieved through beam control of the antenna.
