Description

Background Art

[0001] Background An electronic device may include one or more antennas for transmitting and receiving signals in various communication bands. Antenna design for small electronic devices such as wearable devices can be difficult because the form factor of such devices is constrained. For example, a smartphone may have limited space for accommodating an antenna, but in the case of a wearable device having a compact form factor, the space is even smaller. Due to such limited space, the antenna performance, which can be measured by radiation efficiency and bandwidth, is affected. For example, larger antennas typically have higher efficiency. The antenna performance for wearable devices can also be severely affected by the human body effect because it may cause detuning, attenuation, and / or shadowing of the antenna when in very close proximity to the wearer. In addition, these problems are exacerbated when multiple antennas are implemented in a device and used to support various different common communication standards.

[0002] Some electronic devices have a display module that includes a display and circuitry for displaying information on the display. Some of these electronic devices also have a display shield, which is a physical component that separates (or shields) the components of the display module.

For example, the antenna can be formed as a display shield and can function as a radiating element and an antenna. The display shield can separate components such as a printed circuit board or a battery for the device from other components. An antenna system including the display shield and one or more tuning circuits can be configured to tune the display shield for multi-band frequency transmission. The display shield can be electrically insulated from the display module and can be electrically grounded to the housing of the device. At the same time, the display shield can be positioned within the device such that it does not come into direct contact with the user's body, for example, when the device is a wearable device such as a smartwatch.

[0004] By physically separating the display shield from the user in this way, interference from the user's body can be reduced. This interference can, in some cases, be caused by interfering body effects and / or the user's body physically blocking incoming and outgoing signals transmitted from the antenna. Examples of body effects can include shadowing, such as preventing the antenna from receiving a signal, detuning, such as changing the frequency of the antenna, and attenuation, such as reducing the amplitude of incoming and / or outgoing signals.

[0023] Detailed Description Summary: The present disclosure provides an example of a display shield for a display module, where the display shield is co-designed as an antenna on an electronic device. For example, the electronic device can be a wristwatch, a smartphone, an e-book reader, or any electronic device with a display. The display shield can function as a multi-band antenna and can be configured to receive and / or transmit radio frequency waves. When implemented as part of a wearable device, the display shield can be physically isolated from the user's body.

[0024] The display shield can be a planar disk or other shape that can match or approximate the shape and size of the display for the device. The display shield can be configured to support a current or magnetic field that directly contributes to the radiation pattern of the antenna. The display shield can be made from any conductive material such as one or more metals or alloys. Other configurations for the display shield are also possible and are described in detail herein. The display shield can be grounded by a clip attached to the display shield.

[0025] The display shield can function as an antenna as part of an antenna system for the device. The antenna system can include an antenna feed and a shorting pin that can establish an electrical connection from the display shield to a radio chipset and an antenna tuning circuit. The radio chipset and the antenna tuning circuit can be components of the device and can be physically separated from the display module by the display shield. The antenna tuning circuit can tune the antenna system to receive and / or transmit radio frequency signals along various different frequency bands through the display shield. The antenna tuning circuit and / or the radio chipset can be implemented as part of the main logic board for the electronic device.

[0026] The display shield can be partially located within a device housing that houses various components such as a battery or a main logic board. In some examples, the display shield can define an aperture for a flexible printed circuit tail or other electrical connectors for connecting various components of the electronic device to components of the display module. In some examples, the flexible printed circuit tail provides additional grounding for the display shield.

[0027] The antenna system can include a feed blade or spring clip for electrically connecting the display shield to the antenna tuning circuit. The antenna system can include a plurality of antenna tuning circuits electrically connected to the display shield through a shorting blade, spring clip, or other type of connector.

[0028] Aspects of the present disclosure can provide for efficient operation of a device, particularly for small wearable electronic devices. The antenna system is disposed within the device housing such that it can take a physical distance between the antenna system and the body of the user operating the device, taking into account the body effect and reduction of specific absorption rate. At the same time, since at least the display shield functioning as an antenna can be made to have a shape and size that is the same as the corresponding display for the device, a relatively large antenna can be made possible with the provided antenna system. The antenna system can be tuned to obtain multi-band performance over various frequency bands corresponding to common wireless communication standards such as cellular communication, UMTS (Universal Mobile Telecommunications System) communication, Wi-Fi® communication, Bluetooth® communication, GPS communication, and Long Term Evolution (LTE®) communication.

[0029] The display shield can be configured to receive and / or transmit radio frequency signals over a variety of different frequency bands, reducing or eliminating the need to add elements within a physically constrained device to function as all or part of an antenna. Further, instead of implementing multiple antennas on a device that already has a display shield implemented, the display shield itself can be adaptively tuned to meet communication requirements over multiple frequency bands. Thus, at least, the available physical space within the device can be used more efficiently since the display shield is co-designed to function as a multi-band antenna while protecting the display component of the display module.

[0030] An antenna system comprising a display shield configured as described herein can be implemented across a variety of different devices such as smart watches, tablets, personal computers, smart phones, and generally any device having a display. In the case of wearable devices such as smart watches, the antenna system can be implemented with a variety of different materials to secure the device on the user's body when worn. For example, the antenna system can function robustly with various strap-like materials such as metal, rubber, leather, or various types of fabric.

[0031] Exemplary System: Figures 1A - 1D show an exemplary display module with a display shield that can be part of an electronic device. The device can implement an antenna system that includes the display shield of the display module. The exemplary electronic device can be a wearable device, such as a smart watch. However, it should be understood that an exemplary antenna system with a display shield as described herein can be implemented in any of a variety of electronic devices with a display, including both wearable and non-wearable devices such as smart phones, tablets, laptops, and televisions.

[0032] Figure 1A shows an exploded view of an exemplary display module 101 with a display shield 100, in accordance with aspects of the present disclosure. The display module 101 may include a display component 102 for implementing any of a variety of different displays. For example, the display module 101 may be a module for a liquid crystal display (LCD), a light-emitting diode display (LED), an organic light-emitting diode display (OLED), a plastic organic light-emitting diode display (pOLED), or an electronic ink display. The display component 102 may include any component of the display module 101 sandwiched between the display shield 100 and the cover 103.

[0033] Depending on the type of display being implemented, the display component 102 may include components for implementing that type of display. For example, the display component 102 may include a light-emitting layer that includes light-emitting diodes on a substrate, and other components for passing current through the light-emitting layer. The display component 102 can be positioned behind the cover 103, which can be glass or plastic, or any material that generally does not make the light-emitting layer for the display completely opaque. In some examples, the light-emitting layer of the display component 102 can be laminated on the cover 103 or adhered to the cover 103 using a transparent adhesive material.

[0034] In some examples, the display component 102 can implement the display as a display panel that includes one or more light-emitting layers sandwiched between transparent panels made of materials such as glass or plastic. The display panel can include additional materials such as polarizing films, filters, and the like.

[0035] The display component 102 can include any of various other components available on an electronic device with a display, such as a capacitive layer or a resistive layer made of a material for receiving touch input to the display module 101. The display module 101 can be configured to receive and process touch input and output images, text, or video. In some examples, the display component 102 can include an ambient light sensor (ALS) and can be configured to receive and process signals received by the ALS. The display module 101 can be configured to adapt the brightness of the display based on, for example, the intensity of light measured by the ALS. The display component 102 can be electrically connected to other components of the electronic device via a display flexible printed circuit (FPC) tail 105. In some implementations, the display component 102 is electrically connected to other components of the device by wires, traces, or other conductive materials.

[0036] The FPC tail 105 can transmit and receive electrical signals between the display module 101 and other components such as the battery or the main logic board of the electronic device implementing the display module 101. The display component 102 may also include exposed copper or other conductive material for fixing one end of the display FPC tail 105 to the display component 102. The FPC tail 105 can be made longer than the length required to connect the display component 102 to other components of the electronic device in order to enable a service loop during device assembly. The display shield 100 may define an aperture 107 shaped and sized to allow the FPC tail 105 to penetrate the display shield 100.

[0037] The display shield 100 can physically separate the display component 102 from other components of the electronic device implementing the display module 101. The display shield 100 can be made of metal or can be made of a conductive non-metallic material such as graphite. In some examples, the display shield is coated with a conductive material. The display shield 100 can be attached to the display component 102 with an adhesive material layer 106. The adhesive material layer 106 can be, for example, a pressure sensitive adhesive (PSA).

[0038] The display shield 100 may have substantially the same shape and the same size as the display for the display module 101 along a plane. For example, when the display module 101 has a circular display, the display shield may have a circular shape and may be sized to sandwich the display component 102 with the cover 103. The cover 103 may extend at least partially to the side surface 104 of the display module 101. The display shield 100 may have an appropriate size and shape to fit in the same plane as the cover 103 or to fit partially within the cover 103. In some implementations, the display shield 100 may have other shapes such as rectangular, triangular, elliptical, etc.

[0039] The display shield 100 may include one or more shield ground clips 108. In some examples, the shield ground clip 108 can be attached to the side surface of the display shield 100 facing away from the display component 102. Additionally, the display shield 100 may include a blade clip 109 formed to accommodate an antenna blade for electrically connecting the display shield 100 to other components of the electronic device described herein. The blade clip 109 may be a curved part of a conductive material attached to the display shield 100 and may be configured to hold the blade in place when inserted between the curved parts. The blade can form an electrical connection between the display shield 100 and other components of the antenna system, such as the tuning circuit and / or wireless chipset described herein. The number of the shield ground clip 108 and the blade clip 109, as well as their positions relative to each other, may vary depending on, for example, the positions of other components of the electronic device.

[0040] Figure 1B shows a perspective view of an exemplary display module 101 comprising a display shield 100 and a display flexible printed circuit tail 105, in accordance with aspects of the present disclosure. Figure 1B shows the display shield 100 partially positioned within the cover 103. In some implementations, the display shield 100 may be flush with the edge of the cover 103 instead of being partially positioned within the cover 103. Since the display component 102 of the display module 101 is sandwiched between the cover 103 and the display shield 100, the display component 102 is hidden in Figure 1B. The display shield 100 may have a smooth surface or may be grooved in one or more locations to provide extra space for the display component 102 when sandwiched between the cover 103 and the display shield 100. The FPC tail 105 is also shown in Figure 1B as passing through the display shield 100.

[0041] Figure 1C shows an exploded view of an exemplary display module 101 comprising a display shield 100, a cover 103, and a display component 102, in accordance with aspects of the present disclosure. The cover 103 can be shaped and sized to completely cover the display 111 while allowing the contents of the display 111 to be visible and protecting the display 111 from damage. In an example where the display module 101 is configured to receive touch input, the cover 103 also allows the touch input to pass through the cover 103 and the display component 102. In Figure 1C, the display module 101 is shown as including a near field communication (NFC) module 113. The NFC module 113 can be configured to send and receive data with other NFC-enabled devices.

[0042] The NFC module 113 can be positioned along the display shield 100, which can function as a carrier to improve the performance of the NFC module 113.

[0043] Figure 1D shows a cross-sectional view of an exemplary display module 101 including a display shield 100, a cover 103, and a display component 102, in accordance with aspects of the present disclosure. As described with reference to FIGS. 1A and 1B, the display shield 100 and the cover 103 can sandwich the display component 102 therebetween. Further, the display shield 100 can be positioned at least partially within the cover 103, and the cover 103 extends at least partially covering the side surface 104 of the display module 101. FIG. 1D also shows a gap 115 formed between the display shield 100 and the cover 103. The display shield 100 can extend past the display component 102 to form the gap 115, allowing a wireless signal to pass through the gap 115, and further improving the signal quality by increasing at least the overall surface area on the display shield 100 and providing additional space for the signal to pass through.

[0044] FIG. 2 shows an exploded view of an antenna system 200 including a display shield 100, in accordance with aspects of the present disclosure. The antenna system 200 can be implemented as part of an electronic device having a display, such as a smartwatch. The antenna system 200 can include a display shield 100, a shorting blade 207, antenna tuning circuits 206A, 206B, a feeding blade 211, and a wireless chipset 213.

[0045] Antenna tuning circuits 206A, 206B, and wireless chipset 213 can be positioned on main logic board 203 for an electronic device. Main logic board 203 can be positioned within housing 215. Other components of the electronic device, such as a battery, can also be positioned within housing 215 and separated from display component 102 by display shield 100. Housing 215 may further be adapted to be modularly attached to other components. For example, as illustrated, when the device is a smartwatch, housing 215 may be adapted to be attached to a watch band. The watch band can be made of any suitable material, including metal, ceramic, leather, polymer, fabric, and the like.

[0046] Housing 215 itself can be a housing for an electronic device. Housing 215 can be made of a conductive material or can be coated with a material such as metal or plastic. Display shield 100 can form a ground connection with housing 215 through shield ground clip 108.

[0047] Display shield 100 can function as a radiating element configured to receive and transmit radio frequency signals at various frequencies. Power supply blade 211 can electrically connect display shield 100 to wireless chipset 213. Wireless chipset 213 can include one or more circuits configured to receive incoming radio frequency signals from display shield 100 and transmit outgoing radio frequency signals to display shield 100 for transmission. The wireless chipset can function as a cellular modem and can be configured to receive and transmit cellular signals and signals over a variety of different frequency bandwidths, as described herein. Power supply blade 211 can be connected to the display shield by coupling with blade clip 109.

[0048] In some implementations, the power supply blade 211 can be attached to the display shield 100 by other means such as directly attaching to the display shield 100 without using the blade clip 109. The wireless chipset 213 can be integrated as part of the main logic board 203. In some implementations, the wireless chipset 213 is a separate component of an electronic device that can be coupled to the main logic board 203 using, for example, wires or conductive traces.

[0049] The antenna system 200 can include a tuning circuit 206A electrically connected between the wireless chipset 213 and the power supply blade 211. The power supply blade 211 can be connected to the display shield 100 via the blade clip 109. Generally, the tuning circuit 206A can be configured to tune the resonant frequency of the display shield 100 to operate according to various different frequency bands. For example, the antenna system 200 can be configured to operate at various frequencies commonly associated with the LTE (registered trademark) communication standard, including a low-band frequency range of 700 MHz to 960 MHz, a mid-band frequency range of 1710 MHz to 2200 MHz, and a high-band frequency range of 2500 MHz to 2700 MHz.

[0050] Other frequency bands in which the antenna system 200 can operate can include the frequency range of the GNSS frequency band including the GPS frequency centered at 1575.42 MHz, the GLONASS frequency of 1596 MHz to 1607 MHz, and the BeiDou frequency centered at 1561.098 MHz. Additionally, or alternatively, the antenna system 200 can be tuned to operate within the frequency range of 2400 MHz to 2484 MHz for Wi-Fi (registered trademark) signals and Bluetooth (registered trademark) signals. Thus, the antenna system 200 can cover the LTE communication band, the GPS communication band, and the communication bands of Wi-Fi (registered trademark) and Bluetooth (registered trademark).

[0051] The antenna system 200 may include a plurality of tuning circuits 206A - 206B as shown, for further fine - tuning the resonant frequency of the display shield 100 within a frequency band. For example, the tuning circuit 206B can be electrically connected to the short - circuit blade 207. The short - circuit blade 207 and the blade clip 109B can be short - circuit pins that are between the tuning circuit 206B and the main logic board 203 and are connected to the display shield 100. The tuning circuit 206B can be configured to fine - tune the resonant frequency of the display shield 100 tuned by the tuning circuit 206A. In some implementations, the antenna system 200 may include more or fewer tuning circuits. For example, in some implementations, the antenna system 200 may include a single tuning circuit configured to tune the display shield according to various different frequency bands. The tuning circuits 206A - 206B can achieve frequency matching, improve antenna efficiency, and reduce the specific absorption rate.

[0052] Also, the display FPC tail 105 shown in FIG. 2 can further ground the display shield 100 in addition to the ground clip 108. In some implementations, the display shield 100 can be grounded only by the ground clip 108 or only by the display FPC tail 105.

[0053] Figures 3A to 3D are diagrams showing various exemplary antenna systems. For each of Figures 3A to 3D, a main logic board of an exemplary electronic device implementing the exemplary antenna system is shown in a top-down perspective view. As recalled from Figure 2, as one possible arrangement, the main logic board 203 can be positioned within the housing 201 and electrically connected to the display shield 100 via the FPC tail 105 and the antenna blades 207, 211. In addition to the components shown with reference to Figures 3A to 3D, the main logic boards 301A to 301D can include other components not shown. For example, the main logic boards 301A to 301D can include a radio chipset for receiving and processing radio frequency signals.

[0054] Figure 3A is a diagram of a first exemplary antenna system 300A according to an aspect of the present disclosure. On the main logic board 301A, the first exemplary antenna system can include a power supply 302A, a plurality of ground points 303A, a tuning circuit 306A, a shorting pin 307A, and an antenna feed 309A. The tuning circuit 306A can also be grounded by the ground point 311A. The plurality of ground points 303A can ground the display shield and can be positioned as far as physically possible from the antenna feed 309A on the main logic board 301A. In some implementations, the plurality of ground points 311A can also be arranged at other positions relative to the antenna feed 309A and / or the tuning circuit 306A and the antenna feed 309A.

[0055] FIG. 3B is a diagram of a second exemplary antenna system 300B according to an aspect of the present disclosure. In FIG. 3B, the main logic board 301B is rectangular in shape and can conform to the shape of other components of the electronic device, such as its display shield and display (not shown). As described herein, the size and shape of the display shield may vary depending on the size and shape of the housing. The main logic board 301B can likewise be made to have a shape and size such that distances, for example, the distance between the corners of the main logic board 301B, the distance between the ground point 303B and the antenna feed 309B, etc., can be made wider. The main logic board 301B may also include a tuning circuit 306B grounded by a ground point 311B. The main logic board 301B may also include a power supply 302B and a short circuit pin 307B.

[0056] FIG. 3C is a diagram of a third exemplary antenna system 300C according to an aspect of the present disclosure. In the third exemplary antenna system 300C, the antenna short circuit pin 307C can be configured as a second antenna feed in addition to the antenna feed 309C. By adding the second antenna feed, in some cases, the potential bandwidth range for the third exemplary antenna system 300C can be widened, and furthermore, the overall transmission can be improved. The main logic board 301C may also include a power supply 302C connected to the tuning circuit 306C. The tuning circuit 306C can be grounded by a ground point 311C. Similar to the main logic boards 301A - 301B shown in FIGS. 3A and 3B, the main logic board 301C may also include a ground point 311C for grounding a display shield (not shown).

[0057] Multiple feeds can also make it possible to spread the frequency range, so that various feeds can each be responsible only for receiving signals at their respective different frequencies. Multiple feeds can also provide for rapid switching between feeds in response to various operations performed by the electronic device. For example, the device can be configured to perform an operation that requires transmission to both Bluetooth® signals and Wi-Fi® signals. The Bluetooth® signals and Wi-Fi® signals can each be assigned to their respective feeds. The antenna system 300C can be configured to switch the power supply according to which type of signal is required to perform the operation at that time. In some examples, the antenna system 300C with multiple antenna feeds can make it possible to perform operations simultaneously in response to signals of multiple frequencies.

[0058] FIG. 3D is a diagram of a fourth exemplary antenna system 300D according to an aspect of the present disclosure. In the fourth exemplary antenna system 300D, the antenna shorting pins are completely removed. In addition, the display shield is grounded by a single ground point 303D on the main logic board 301D. The ground point 303D can be an FPC tail that connects the main logic board 301D to a display component of a display module (not shown). The main logic board 301D can also include a power supply 302D, an antenna feed 309D, and a tuning circuit 306D with a ground point 31ID.

[0059] Although various specific variations are shown between the exemplary antenna systems of FIGS. 3A-3D, it should be understood that the various implementations of the disclosed subject matter provide exemplary antenna systems with various features. In one example, the exemplary antenna system can have a second antenna feed and a single ground point replaced by an FPC tail. In another example, the display shield and the main logic board can be rectangular and can include a plurality of tuning circuits with shorting pins configured to function as antenna feeds.

[0060] Figure 4 is a circuit diagram 400 for an exemplary antenna system according to aspects of the present disclosure. Antenna feed 403 can couple the display shield to the rest of the circuit, as shown in FIG. 4. Power source 405 can be a battery or other power source for the exemplary antenna system and can be connected to circuit ground point 410. Circuit diagram 400 also shows matching circuit 420 and tuning circuit 430.

[0061] A matching circuit is an impedance transformation circuit that ensures proper impedance matching by transforming the impedance of either or both of the radio wave source and the load. Matching circuit 420 can include components such as inductors and capacitors. For example, matching circuit 420 may increase or decrease the impedance of the radio wave source to match the impedance of the first antenna. Alternatively or additionally, matching circuit 420 may increase or decrease the impedance of the display shield to match the impedance of the radio wave source.

[0062] Circuit diagram 400 also shows a ground point 440 that can include a shield ground clip as shown with reference to FIGS. 1A-1D and FIG. 2.
