Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a signal transceiver control method and apparatus for an integrated display housing antenna. Background Technology

[0002] As display devices evolve towards thinner, lighter designs and higher integration, the compatibility issues between wireless communication functions and metal casings are becoming increasingly prominent. Traditional display wireless communication solutions typically employ independent antenna components, such as flexible circuit board antennas, laser-formed antenna brackets, or printed circuit board antennas. These antenna components are fixed inside the display casing by adhesive, screws, or thermoforming posts, and connected to the motherboard's RF circuitry via RF coaxial cables or spring clips. However, this approach has inherent drawbacks: independent antenna components occupy valuable space within the display, including the antenna itself, mounting brackets, fixing structures, and RF cable routing areas, directly conflicting with the trend towards thinner and lighter displays. Furthermore, as consumers increasingly demand a premium product appearance, metal casings are widely used in display products. However, metal casings can create a Faraday cage effect on the built-in independent antenna, severely shielding wireless signals and significantly reducing antenna radiation efficiency.

[0003] To address the issue of metal shielding, existing technologies typically involve creating plastic breaks in the casing or increasing the area of ​​the non-metallic region. However, this approach compromises the aesthetic appeal of the casing, and the antenna position remains limited by the non-metallic area, preventing flexible adjustments based on interference conditions. Furthermore, various electromagnetic interference sources exist within the display, such as the digital processor, power management module, and backlight drive circuit. The operating frequencies and harmonics generated by these sources can enter the antenna receiving path through spatial coupling or conduction, affecting wireless communication quality. Summary of the Invention

[0004] This application provides a signal transceiver control method and apparatus for an integrated antenna on a display housing, which is used to solve the problem of electromagnetic interference generated by internal interference sources of the display affecting the quality of wireless communication in related technologies.

[0005] The first aspect of this application provides a signal transceiver control method for an integrated display housing antenna, the method comprising: The first metal block in the display casing is connected to the motherboard radio frequency circuit, and the first metal block is controlled as the first antenna radiation area for signal transmission and reception. Real-time acquisition of the operating frequency of interference sources inside the display, and determination of the target interference frequency band based on the operating frequency; Monitor the reflection coefficient of the radiation area of ​​the first antenna and compare the target interference frequency band with the preset harmonic frequency band; When the reflection coefficient is greater than the preset reflection threshold, or the target interference frequency band is within the preset harmonic frequency band range, a matching second metal block is determined from the other metal blocks of the display casing; The connection point with the motherboard's RF circuit is switched from the first metal block to the second metal block, and the second metal block is used as the second antenna radiation area for signal transmission and reception.

[0006] Optionally, in the first implementation of the first aspect of this application, the step of real-time acquisition of the operating frequency of the interference source inside the display and determining the target interference frequency band based on the operating frequency includes: Collect the operating frequencies of multiple preset interference sources inside the display, and generate a set of interference frequency points corresponding to each interference source, which includes the operating frequency and the corresponding preset number of multiplications. The interference frequency point sets corresponding to each interference source are matched pairwise. When there is a target frequency point in any two interference frequency point sets with a frequency difference less than a preset frequency difference threshold, the target frequency point is recorded as a common interference frequency point, and a merged interference frequency band containing the common interference frequency point and the corresponding preset harmonic is generated. The merged interference frequency band is compared with the center frequency of the current signal transmission and reception to determine the target interference frequency band whose difference from the center frequency is less than the preset protection bandwidth.

[0007] Optionally, in a second implementation of the first aspect of this application, the step of determining a matching second metal block from other metal blocks of the display housing includes: Read the pre-stored metal block information table, which contains the position coordinates of each metal block in the display casing and the radiation efficiency data of each metal block in each preset frequency band; Based on the location coordinates of the interference source and the location coordinates of each other metal block, the spatial distance between each other metal block and the interference source is determined, and a first score value for each other metal block is generated based on the spatial distance. Based on the target interference frequency band, extract the radiation efficiency data of each other metal block under the target interference frequency band from the metal block information table, and generate a second score value for each other metal block based on the radiation efficiency data. Obtain the current reflection coefficient of each other metal block, and generate a third score value for each other metal block based on the reflection coefficient; The first score, the second score, and the third score of each other metal block are weighted to generate a comprehensive score for each other metal block, and the metal block with the highest comprehensive score is determined as the second metal block.

[0008] Optionally, in a third implementation of the first aspect of this application, the step of switching the communication object with the motherboard radio frequency circuit from the first metal block to the second metal block, and using the second metal block as a second antenna radiation area for signal transmission and reception, includes: The first radiation efficiency data of the first metal block under the target interference frequency band is compared with the second radiation efficiency data of the second metal block under the target interference frequency band to generate the radiation efficiency change. When the change in radiation efficiency is greater than a preset change threshold, the radio frequency transmission power is adjusted from a first power value to a second power value. The first power value is the radio frequency transmission power before the switch, and the second power value is the temporary transmission power during the switch. Based on the second power value, the connection object with the motherboard RF circuit is switched from the first metal block to the second metal block; After the switching is completed, the radio frequency transmission power is restored from the second power value to the first power value, and the second metal block is used as the second antenna radiation area for signal transmission and reception.

The power adjustment mapping table includes several radiation efficiency ratio ranges, several link quality levels, and power adjustment coefficients corresponding to each radiation efficiency ratio range and each link quality level. The second power value is generated based on the first power value and the power adjustment coefficient.

[0010] A second aspect of this application provides a signal transceiver control device for an integrated display housing antenna, which is used to implement a signal transceiver control method for an integrated display housing antenna. The integrated display housing antenna control device includes: The control module is used to connect the first metal block in the display casing to the motherboard radio frequency circuit and control the first metal block as the first antenna radiation area for signal transmission and reception. The acquisition module is used to acquire the operating frequency of the interference source inside the display in real time, and determine the target interference frequency band based on the operating frequency; The comparison module is used to monitor the reflection coefficient of the radiation area of ​​the first antenna and compare the target interference frequency band with the preset harmonic frequency band; The determination module is used to determine a matching second metal block from other metal blocks of the display casing when the reflection coefficient is greater than a preset reflection threshold, or when the target interference frequency band is within a preset harmonic frequency band range; The switching module is used to switch the connection object with the motherboard RF circuit from the first metal block to the second metal block, and to use the second metal block as the second antenna radiation area for signal transmission and reception.

[0011] Optionally, the acquisition module further includes: The acquisition unit is used to acquire the operating frequencies of multiple preset interference sources inside the display, and generate a set of interference frequency points corresponding to each interference source, which includes the operating frequency and the corresponding preset number of multiplications. The matching unit is used to match the sets of interference frequency points corresponding to each interference source in pairs. When there is a target frequency point in any two sets of interference frequency points with a frequency difference less than a preset frequency difference threshold, the target frequency point is recorded as a common interference frequency point, and a merged interference frequency band containing the common interference frequency point and the corresponding preset harmonic is generated. The comparison unit is used to compare the merged interference frequency band with the center frequency of the current signal transmission and reception, and determine the target interference frequency band whose difference from the center frequency is less than the preset protection bandwidth.

[0012] Optionally, the determining module further includes: The reading unit is used to read the pre-stored metal block information table, which includes the position coordinates of each metal block in the display casing and the radiation efficiency data of each metal block in each preset frequency band.

The determining unit is used to weight the first score value, the second score value and the third score value of each other metal block to generate a comprehensive score value for each other metal block, and to determine the metal block with the highest comprehensive score value as the second metal block.

[0013] A third aspect of this application provides an electronic device, including a memory and a processor, wherein the processor is configured to execute a computer program stored in the memory, and when the processor executes the computer program, it implements the steps of the integrated signal transceiver control method for display housing and antenna provided in the first aspect of this application.

[0014] The fourth aspect of this application provides a computer-readable storage medium storing a computer program thereon.

[0015] In summary, the integrated signal transceiver control method and apparatus for a display housing antenna provided in this application connects a first metal block in the display housing to the motherboard radio frequency circuit, controlling the first metal block as the first antenna radiation area for signal transmission and reception. The operating frequency of the internal interference source is collected in real time, and the target interference frequency band is determined based on the operating frequency. The reflection coefficient of the first antenna radiation area is monitored, and the target interference frequency band is compared with a preset harmonic frequency band. When the reflection coefficient is greater than a preset reflection threshold, or the target interference frequency band is within the preset harmonic frequency band range, a matching second metal block is determined from other metal blocks in the display housing. The connection to the motherboard radio frequency circuit is switched from the first metal block to the second metal block, and the second metal block is used as the second antenna radiation area for signal transmission and reception. This application uses multiple metal blocks formed by nano-injection molding as dynamically switchable antenna resources. When harmonic interference is detected from an interference source, a metal block far from the interference source and with low radiation efficiency in the interference frequency band can be selected from multiple metal blocks on the housing for switching, actively avoiding the interference source and thus ensuring signal transmission and reception quality.

Detailed Implementation

[0017] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] To address the issue of electromagnetic interference from internal interference sources in displays affecting wireless communication quality in related technologies, embodiments of this application provide a signal transceiver control method integrating an antenna into the display casing, such as... Figure 1 This is a flowchart illustrating the integrated signal transceiver control method for a display housing antenna provided in this embodiment. The integrated signal transceiver control method for a display housing antenna includes the following steps: Step 110: Connect the first metal block in the display casing to the motherboard radio frequency circuit, and control the first metal block as the first antenna radiation area for signal transmission and reception.

[0019] Specifically, this embodiment utilizes nano-injection molding to embed insulating strips into the metal casing of the display, dividing the originally complete metal casing into multiple electrically isolated metal blocks. At least one of these metal blocks is electrically connected to the motherboard's radio frequency circuit via a radio frequency feeding structure, allowing the metal block to directly act as an antenna radiator for transmitting and receiving wireless signals. This eliminates the need for a separate antenna assembly, freeing up internal space in the display, and making the antenna itself part of the casing structure, thus eliminating the signal shielding problem of the metal casing for traditional built-in antennas.

[0020] Step 120: Collect the operating frequency of the internal interference source of the display in real time, and determine the target interference frequency band based on the operating frequency.

[0021] Specifically, by real-time monitoring of the operating frequencies of multiple preset interference sources inside the display, including typical electromagnetic interference sources such as digital processors, power management modules, and backlight drive modules, the operating frequencies of these sources are collected and expanded by their harmonics to form a complete set of interference frequency bands covering the fundamental frequency and multiple harmonics. This set is then correlated and filtered with the current signal transmission and reception frequency bands to finally determine the target interference frequency bands that truly pose a threat to current wireless communication, providing accurate interference characteristic basis for antenna switching.

[0022] Step 130: Monitor the reflection coefficient of the radiation area of ​​the first antenna and compare the target interference frequency band with the preset harmonic frequency band.

[0023] Specifically, during signal transmission and reception, the reflected signal power is read in real time through the bidirectional coupler integrated in the RF front end. The reflection coefficient is calculated based on the transmitted signal power and the reflected signal power to determine the matching status between the current antenna radiation area and the RF circuit. At the same time, the target interference frequency band is compared with the system's preset harmonic frequency band range. Through the comprehensive judgment of the dual conditions of reflection coefficient and interference frequency band, the triggering time of antenna performance degradation or external interference aggravation can be accurately identified.

[0024] Step 140: When the reflection coefficient is greater than the preset reflection threshold, or the target interference frequency band is within the preset harmonic frequency band range, determine the matching second metal block from the other metal blocks of the display casing.

[0025] Specifically, the preset reflection threshold refers to a critical value of the reflection coefficient pre-stored in the display's memory. This critical value is used to determine whether the matching state between the current antenna radiation area and the RF circuit meets the signal transmission and reception requirements. The specific value of the preset reflection threshold is determined based on the tolerance capability of the RF power amplifier and the error vector amplitude requirements of the communication protocol, typically ranging from 0.2 to 0.3. When the reflection coefficient exceeds the preset reflection threshold or the interference frequency band enters the harmonic influence range, other metal blocks in the casing are screened. This selection is based on the differences in spatial distribution and electrical characteristics of each block. The distance between metal blocks at different locations and the interference source varies, and the electromagnetic coupling strength they experience also differs. At the same time, the radiation efficiency of each block in a specific frequency band varies. By comprehensively considering the distance relationship, frequency band adaptability, and current matching state, a second metal block that is more conducive to signal radiation can be determined.

[0026] Step 150: Switch the connection object with the motherboard RF circuit from the first metal block to the second metal block, and use the second metal block as the second antenna radiation area for signal transmission and reception.

[0027] Specifically, the RF path is switched from the currently connected first metal block to the second metal block selected through comprehensive evaluation by an antenna switch. During the switching process, the RF transmission power is adaptively adjusted according to the difference in radiation efficiency between the two metal blocks in the target interference frequency band. After the switching is completed, the original transmission power is restored to ensure that the signal transmission and reception remain continuous and stable during the switching process. At the same time, the physical isolation characteristics of the nano-injection molded insulating isolation strip are used to make the antenna radiation area after the switch have a larger spatial distance and lower frequency band sensitivity from the interference source, thereby achieving the technical effect of actively avoiding interference.

[0028] In one optional implementation of this embodiment, the step of real-time acquisition of the operating frequencies of interference sources inside the display and determining the target interference frequency band based on the operating frequencies includes: acquiring the operating frequencies of multiple preset interference sources inside the display; generating interference frequency point sets corresponding to each interference source, each containing the operating frequency and its corresponding preset harmonic; matching the interference frequency point sets corresponding to each interference source pairwise; when any two interference frequency point sets contain a target frequency point with a frequency difference less than a preset frequency difference threshold, recording the target frequency point as a common interference frequency point, and generating a merged interference frequency band containing the common interference frequency point and its corresponding preset harmonic; comparing the merged interference frequency band with the center frequency of the current signal transmission and reception, and determining the target interference frequency band whose difference from the center frequency is less than a preset protection bandwidth.

[0029] Specifically, interference sources include, but are not limited to, digital processors, power management modules, and wireless communication modules. Multiple pre-set interference sources within the display generate specific operating frequencies during operation. These operating frequencies refer to the fundamental frequency signal generated by the interference source's own oscillation or switching action. Taking a digital processor as an example, when its operating frequency is 1.2 GHz, this frequency is the operating frequency of one interference source. Since electromagnetic interference not only exists at the operating frequency itself but also radiates outwards in integer multiples of that frequency, it is necessary to extend the frequency by multiplying the operating frequency by a harmonic. A harmonic is the frequency value obtained by multiplying the operating frequency by an integer multiple, where the second harmonic is twice the operating frequency, the third harmonic is three times the operating frequency, and so on. For an interference source with an operating frequency of 1.2 GHz, its second harmonic is 2.4 GHz, and its third harmonic is 3.6 GHz. These harmonics also constitute potential interference frequencies. By pre-setting the harmonics, the operating frequency of the interference source and its harmonics are included in a set, thus forming the set of interference frequencies corresponding to that interference source. After acquiring the operating frequencies of multiple interference sources, a frequency multiplication operation is performed on each interference source to obtain its own independent set of interference frequencies. When pairwise matching of the interference frequency sets corresponding to each interference source, all frequency points in the two sets need to be compared one by one, and the frequency difference between any two frequency points needs to be calculated. A preset frequency difference threshold is used to determine whether two frequency points can be considered as the same frequency point. This threshold is set to an acceptable frequency tolerance range, for example, 10 MHz. When there are frequency points in two interference frequency sets with a frequency difference less than this threshold, it indicates that two different interference sources have generated superimposed interference at close frequency positions, and this frequency point is recorded as a common interference frequency point. Taking a digital processor with an operating frequency of 1.2 GHz and a power management module with an operating frequency of 0.8 GHz as an example, the second harmonic of the former is 2.4 GHz, and the third harmonic of the latter is also 2.4 GHz. The difference between the two frequency points is zero, which is less than the preset frequency difference threshold. Therefore, 2.4 GHz is identified as a common interference frequency point. After identifying the common interference frequency, this frequency is further multiplied by a factor of two to generate a combined interference band that includes the common interference frequency and its preset harmonics. This combined interference band covers the common interference frequency itself and all its harmonic positions, including the second and third harmonics. The current signal transmission and reception center frequency refers to the center frequency corresponding to the wireless communication protocol being used by the display. For example, when Wi-Fi communication operates in the 2.4 GHz band, its channel center frequency may be 2.412 GHz, 2.437 GHz, or 2.462 GHz, etc. The preset protection bandwidth is used to define the safe distance between the interference band and the signal transmission and reception center frequency. This bandwidth is set according to the channel width of the communication protocol. For example, for Wi-Fi communication with a 20 MHz channel width, the protection bandwidth can be set to 10 MHz.When comparing the merged interference frequency band with the center frequency of the current signal transmission and reception, the difference between each frequency point in the merged interference frequency band and the center frequency is calculated one by one. Frequency points with a difference less than the preset protection bandwidth are selected, and these frequency points constitute the finally determined target interference frequency band. Using the above example, if the center frequency of the current signal transmission and reception is 2.412 GHz, and the merged interference frequency band includes a 2.4 GHz frequency point, the difference between this frequency point and 2.412 GHz is 12 MHz. If the preset protection bandwidth is 10 MHz, then 12 MHz is greater than 10 MHz, and this frequency point does not pose a threat. If the center frequency is 2.437 GHz, the difference is 37 MHz, and similarly, it does not pose a threat. If the center frequency is 2.462 GHz, the difference is 62 MHz, and also, it does not pose a threat. However, if the current signal transmission and reception is in the 5.8 GHz band with a center frequency of 5.785 GHz, and the combined interference band contains a 4.8 GHz frequency derived from the second harmonic of the common interference frequency of 2.4 GHz, and a 7.2 GHz frequency derived from the third harmonic, the differences between these frequencies and 5.785 GHz are significant and cannot fall within the protection bandwidth. Only when the common interference frequency coincides with the center frequency of the current signal transmission and reception or its harmonics will an interference band with a difference smaller than the protection bandwidth be generated. In this case, the frequency band is identified as the target interference band, thus ensuring that antenna switching can accurately respond to interference sources that truly threaten the quality of signal transmission and reception.

[0030] In an optional embodiment of this example, the step of determining a matching second metal block from other metal blocks in the display casing includes: reading a pre-stored metal block information table, which contains the position coordinates of each metal block in the display casing and the radiation efficiency data of each metal block in each preset frequency band; determining the spatial distance between each other metal block and the interference source based on the position coordinates of the interference source and the position coordinates of each other metal block, and generating a first score value for each other metal block based on the spatial distance; extracting the radiation efficiency data of each other metal block in the target interference frequency band from the metal block information table based on the target interference frequency band, and generating a second score value for each other metal block based on the radiation efficiency data; obtaining the current reflection coefficient of each other metal block, and generating a third score value for each other metal block based on the reflection coefficient; weighting the first score value, second score value, and third score value of each other metal block to generate a comprehensive score value for each other metal block, and determining the metal block with the highest comprehensive score value as the second metal block.

[0031] Specifically, a metal block information table is pre-stored in the display's internal memory. This table records the position coordinates of each metal block on the display casing and the radiation efficiency data of each metal block in each preset frequency band. Position coordinates refer to the spatial positioning parameters of the metal block on the casing plane. A coordinate system is established with the geometric center of the display casing as the origin, and each metal block corresponds to a unique set of horizontal and vertical coordinate values. Radiation efficiency refers to the ratio between the radio frequency energy input to the metal block and the actual outward radiated energy when the metal block acts as an antenna radiator. This ratio varies with the operating frequency band. Different metal blocks will exhibit different radiation efficiency values ​​in the same frequency band due to their different positions on the casing and different surrounding structural environments. After obtaining the position coordinates of the interference source, the distance between these coordinates and the position coordinates of each other metal block in the metal block information table is calculated to obtain the spatial distance between each other metal block and the interference source. The spatial distance reflects the physical proximity of the metal block and the interference source. The greater the distance, the weaker the intensity of the electromagnetic energy generated by the interference source entering the metal block through spatial coupling. When generating the first score based on spatial distance, a correlation is adopted where greater distance results in a higher score, ensuring that metal blocks farther from the interference source receive higher first scores. Based on the target interference frequency band, radiation efficiency data for each other metal block under that frequency band is extracted from the metal block information table. Radiation efficiency data characterizes the response characteristics of a metal block to signals in a specific frequency band. Lower radiation efficiency under the target interference frequency band indicates that the metal block is less sensitive to interference signals in that band, and the proportion of interference energy entering the receiving path through the antenna is smaller. When generating the second score based on radiation efficiency data, a correlation is adopted where lower radiation efficiency results in a higher score, ensuring that metal blocks less sensitive to the target interference frequency band receive higher second scores. The current reflection coefficient of each other metal block is obtained. The reflection coefficient is a physical quantity reflecting the matching state between the metal block and the RF circuit. It is obtained by reading the power ratio of the transmitted signal to the reflected signal in real time through the RF front-end coupler. A lower reflection coefficient indicates a better matching state and less reflection interference caused by impedance mismatch. When generating the third score based on the reflection coefficient, a correlation is adopted where a lower reflection coefficient results in a higher score, thus ensuring that metal blocks with good matching status receive a higher third score. For example, a display casing contains three metal blocks: the first metal block is currently connected, the second metal block is located in the upper left corner of the casing, and the third metal block is located in the lower right corner. The interference source is a digital processor located slightly to the left of the center of the casing. The target interference frequency band is 2.4 GHz. The spatial distance between the second metal block and the interference source is 30 mm, and the spatial distance between the third metal block and the interference source is 120 mm. Based on this, the third metal block receives a higher first score than the second metal block.The second metal block has a radiation efficiency of 65% in the 2.4 GHz band, while the third metal block has a radiation efficiency of 30% in the same band. Based on this, the third metal block has a higher second score than the second. The second metal block currently has a reflection coefficient of 0.3, and the third metal block currently has a reflection coefficient of 0.2. Based on this, the third metal block also has a higher third score than the second. The first, second, and third scores are multiplied by their respective weighting coefficients and then summed to generate the comprehensive score for each of the other metal blocks. The weighting coefficients are dynamically adjusted based on the interference scenario. When the interference source is a high-power device and operates continuously, the weighting coefficient for the spatial distance dimension is increased; when the target interference frequency band highly overlaps with the signal transmission and reception frequency band, the weighting coefficient for the radiation efficiency dimension is increased; when the reflection coefficient fluctuates drastically, the weighting coefficient for the matching state dimension is increased. The metal block with the highest comprehensive score is identified as the second metal block. By comprehensively evaluating three dimensions—spatial distance, radiation efficiency, and reflection coefficient—the metal block with the greatest physical isolation from the interference source, the least sensitivity to the target interference frequency band, and the best current matching status is selected from multiple metal blocks on the outer shell as the switching target. This ensures that the antenna radiation area after switching achieves optimal interference suppression capability in three aspects: physical space, frequency domain characteristics, and electrical matching.

[0032] In one optional embodiment of this example, the step of switching the connection object with the motherboard's radio frequency circuit from a first metal block to a second metal block, and using the second metal block as a second antenna radiation area for signal transmission and reception, includes: comparing the first radiation efficiency data of the first metal block under the target interference frequency band with the second radiation efficiency data of the second metal block under the target interference frequency band to generate a radiation efficiency change; when the radiation efficiency change is greater than a preset change threshold, adjusting the radio frequency transmission power from a first power value to a second power value, where the first power value is the radio frequency transmission power before the switch and the second power value is the temporary transmission power during the switch; based on the second power value, switching the connection object with the motherboard's radio frequency circuit from the first metal block to the second metal block; after the switch is completed, restoring the radio frequency transmission power from the second power value to the first power value, and using the second metal block as a second antenna radiation area for signal transmission and reception.

[0033] Specifically, the change in radiation efficiency is generated by comparing the first radiation efficiency data of the first metal block in the target interference frequency band with the second radiation efficiency data of the second metal block in the same target interference frequency band. Radiation efficiency refers to the ratio between the radio frequency energy input to the metal block and the actual outward radiated energy when the metal block acts as an antenna radiator; this ratio varies with the operating frequency band. Because different metal blocks are located in different positions on the display casing and have different surrounding structural environments, even within the same frequency band, the radiation efficiency of different metal blocks differs. Subtracting the first radiation efficiency data from the second radiation efficiency data and taking the absolute value of the difference yields the change in radiation efficiency. For example, if the display is currently transmitting and receiving Wi-Fi signals through the first metal block, and the first radiation efficiency data of this metal block in the 2.4 GHz band is 60%, after interference detection and target frequency band determination, the second metal block is selected as the switching target, and the second radiation efficiency data of this metal block in the 2.4 GHz band is 30%. Comparing the two, the change in radiation efficiency is 30%. A preset change threshold of 15% is set to determine whether the difference in radiation efficiency between the two metal blocks in the target interference frequency band is significant. Since 30% is greater than 15%, the change in radiation efficiency is determined to exceed the preset change threshold. When the change in radiation efficiency exceeds the preset change threshold, the RF transmit power needs to be adjusted. The first power value is the RF transmit power used for signal transmission and reception through the first metal block before the handover, which is determined by the communication protocol and the current link quality. The second power value is the temporary RF transmit power used during the handover process, which is determined based on the correlation between the first power value and the change in radiation efficiency. Since the radiation efficiency of the second metal block is lower than that of the first metal block, if the transmit power remains unchanged, the actual radiated electromagnetic wave energy after the handover will decrease, which may lead to a momentary deterioration in the communication link quality; if the radiation efficiency of the second metal block is higher than that of the first metal block, the actual radiated energy after the handover will increase, which may exceed the transmit power range allowed by the protocol. Therefore, the RF transmit power is adjusted from the first power value to the second power value at the moment of handover to keep the actual radiated electromagnetic wave energy before and after the handover basically consistent. Continuing the example above, the first power value is 20 milliwatts, corresponding to a 60% radiation efficiency of the first metal block, resulting in an actual radiated energy of 12 milliwatts. The second metal block has a radiation efficiency of 30%. To maintain the actual radiated energy at 12 milliwatts, the second power value needs to be adjusted to 40 milliwatts. Based on the adjusted second power value, the RF path is switched from the first metal block to the second metal block via an antenna switch. This switching operation is completed within microseconds, changing the RF signal transmission path. After the switching is complete, the RF transmit power is restored from the second power value to the first power value.At this point, signal transmission and reception have switched to the second metal block, which has a radiation efficiency of 30%. The actual radiated energy corresponding to the first power value of 20 milliwatts is 6 milliwatts. The recovery operation ensures that subsequent signal transmission and reception follow the power values ​​determined by the communication protocol and link quality, avoiding potential power consumption increases or interference issues that might arise from prolonged use of temporary power values.

[0034] In one optional implementation of this embodiment, when the change in radiation efficiency exceeds a preset threshold, the step of adjusting the radio frequency transmit power from a first power value to a second power value includes: determining the radiation efficiency ratio between the first radiation efficiency data and the second radiation efficiency data; obtaining the received signal strength indication value of the current signal transceiver link, and determining the link quality level of the current signal transceiver link based on the received signal strength indication value; querying the corresponding power adjustment coefficient from a preset power adjustment mapping table based on the radiation efficiency ratio and the link quality level, the power adjustment mapping table containing several radiation efficiency ratio intervals, several link quality levels, and power adjustment coefficients corresponding to each radiation efficiency ratio interval and each link quality level; and generating a second power value based on the first power value and the power adjustment coefficient.

[0035] Specifically, the determination of the radiation efficiency ratio is based on the calculation relationship between the first radiation efficiency data of the first metal block in the target interference frequency band and the second radiation efficiency data of the second metal block in the same target interference frequency band. Radiation efficiency refers to the ratio between the radio frequency energy input to the metal block and the actual outward radiated energy when the metal block acts as an antenna radiator. Dividing the first and second radiation efficiency data yields the radiation efficiency ratio, which reflects the difference in radiation capability between the two metal blocks in the target interference frequency band. For example, in a specific application scenario, the first metal block has a radiation efficiency of 60% in the 2.4 GHz band, while the second metal block has a radiation efficiency of 30% in the same band. Dividing them gives a radiation efficiency ratio of 2, indicating that the radiation efficiency of the first metal block is twice that of the second metal block. The received signal strength indication value is obtained by reading the power level of the received signal in the current signal transceiver link through the baseband processor. This indication value, expressed in decibels and milliwatts, characterizes the signal strength detected by the receiver. The link quality level is determined based on the numerical range of the received signal strength indication value. The received signal strength is divided into several levels; the higher the received signal strength, the higher the link quality level, indicating a better current communication environment. For example, if the current received signal strength indication value of the signal transceiver link is -75 dB / mW, this value falls within the preset range of -80 to -70, and the corresponding link quality level is determined to be medium. A preset power adjustment mapping table is pre-stored in the display's internal memory. This table is organized in a two-dimensional table format, with the horizontal dimension divided into several radiation efficiency ratio ranges and the vertical dimension divided into several link quality levels. Each cell in the table stores a power adjustment coefficient. The preset power adjustment mapping table is established by calibrating the link performance under different radiation conditions, and its core is to establish the correspondence between changes in radiation efficiency and transmit power compensation. In specific implementation, the radiation efficiency differences of different metal blocks in the same frequency band are first obtained, and the radiation efficiency ratio is calculated. Then, the link quality is graded based on the received signal strength indication value. Subsequently, under different combinations of radiation efficiency ratios and link quality levels, the required transmit power adjustment range is measured or simulated to ensure stable signal strength at the receiver during handover. The power adjustment coefficients for each combination are compiled into a table, forming a mapping relationship. In actual operation, the adjustment coefficients are directly obtained from the table based on the current changes in radiation efficiency and link quality status, enabling rapid adaptive adjustment of transmit power. This avoids signal fluctuations caused by antenna switching and improves communication stability. Radiation efficiency ratio ranges are used to categorize continuously changing radiation efficiency ratios into different levels; for example, 0.5 to 1.5 is categorized as the first range, 1.5 to 2.5 as the second range, and so on. Link quality levels are also divided into high, medium, and low levels.The power adjustment factor is a multiplier used to correct the transmit power. Its value is set according to the following principles: when the radiation efficiency ratio is greater than one (i.e., the radiation efficiency of the second metal block is lower than that of the first metal block), the power adjustment factor is greater than one, and the lower the link quality level, the larger the power adjustment factor; when the radiation efficiency ratio is less than one (i.e., the radiation efficiency of the second metal block is higher than that of the first metal block), the power adjustment factor is less than one, and the lower the link quality level, the smaller the power adjustment factor; when the radiation efficiency ratio is equal to one, the power adjustment factor is always one. Based on a radiation efficiency ratio of two and a medium link quality level, the cell corresponding to the radiation efficiency ratio range of 1.5 to 2.5 and the medium link quality level is located from the preset power adjustment mapping table. The power adjustment factor stored in that cell is read, and its value is 1.5. The first power value is the RF transmit power before the handover, which in this example is 20 milliwatts. The first power value is multiplied by the power adjustment factor to generate a second power value of 30 milliwatts. This second power value serves as the temporary transmission power during the switching process, used to compensate for the changes in radiation efficiency caused by the switching of metal blocks, so that the actual electromagnetic wave energy radiated before and after the switching remains continuous and stable.

[0036] In an optional embodiment of this example, before the step of switching the connection object with the motherboard RF circuit from the first metal block to the second metal block, a dynamic antenna resource scheduling step is further included. This step includes: obtaining the protocol type and the operating frequency band occupied by each of the multiple wireless communication modules currently in operation; comparing the operating frequency band of each wireless communication module with the target interference frequency band, and determining that there is a frequency domain conflict between the two wireless communication modules when the frequency interval between the operating frequency bands of any two wireless communication modules is less than a preset frequency interval threshold; determining the time slice allocation ratio of each wireless communication module based on the frequency domain conflict determination result and the real-time traffic data of each wireless communication module; generating a time division multiplexing control timing sequence according to the time slice allocation ratio, wherein the time division multiplexing control timing sequence contains multiple time slices arranged alternately in time, and each time slice corresponds to a wireless communication module; and sending the time division multiplexing control timing sequence to the antenna switch controller, so that the antenna switch switches between each wireless communication module and the currently connected antenna radiation area according to the time division multiplexing control timing sequence.

[0037] Specifically, during device operation, the main control chip obtains the current operating status information of each wireless communication module by accessing its status register. The protocol type identifies the communication standard followed by the module, while the operating frequency band indicates the range of electromagnetic spectrum occupied by the communication. A frequency band is essentially a frequency range measured in Hertz, reflecting the center frequency and bandwidth used for radio frequency signal propagation. In a scenario where wireless projection and Bluetooth audio playback are simultaneously enabled on the same display device, the wireless LAN module reports its protocol type's corresponding operating frequency band as 5.8GHz, and the short-range wireless communication module reports its operating frequency band as 2.4GHz. The main control chip compares the operating frequency bands of each module with a pre-determined target interference frequency band. This target interference frequency band refers to a frequency range where external interference sources are known to exist or where internal sensitive circuits are easily affected. When a module's operating frequency band overlaps with or falls within the coverage area of ​​this frequency band, it indicates that the module may be affected by interference. Furthermore, pairwise comparisons are performed between the operating frequency bands of multiple modules, and frequency intervals are calculated to determine whether frequency domain conflicts exist. Frequency spacing refers to the difference between the center frequencies of two frequency bands. When this difference is less than a preset frequency spacing threshold, it indicates that the two signals are too close in the spectrum, which can easily lead to intermodulation interference or receiver front-end saturation, thus affecting communication quality. This threshold is set based on the transmit spectrum template of each wireless communication protocol and the adjacent channel rejection capability of the receive filter. In a scenario where screen projection and Bluetooth are used concurrently, when the wireless LAN module switches to the 2.4GHz band, its frequency spacing with the Bluetooth module is zero, which is lower than the set threshold, and therefore it is judged to have a frequency domain conflict. After the conflict is determined, antenna resources are allocated based on the real-time traffic data of each module. The real-time traffic data reflects the current demand intensity of each module for communication bandwidth and latency. By comprehensively calculating the traffic load value and latency sensitivity level, the resource priority of each module at the current moment is obtained. This priority is further converted into a time slice allocation ratio. A time slice is the smallest scheduling unit divided on the time axis, and its length determines the time that a module continuously occupies antenna resources. The time slice allocation ratio represents the share of time each module occupies within a scheduling cycle. For example, the Wi-Fi module, due to its higher demand for video data transmission, receives a larger time share, while the Bluetooth module, with its smaller data volume, occupies a shorter time. Based on the time slice allocation ratio, a time-division multiplexing control sequence is constructed. This sequence is essentially a control sequence arranged chronologically, where each time slice contains a module identifier and duration information, indicating the wireless communication module that should be connected within a specific time period. For example, in the scenario described above, a cyclical sequence of "Wi-Fi module 70 milliseconds, Bluetooth module 30 milliseconds" can be generated. This sequence repeats periodically on the time axis, thereby enabling multiple modules to alternately use a single antenna resource.The generated timing sequence is sent to the antenna switch controller via the bus interface. The antenna switch controller internally includes a timing unit and a state transition unit. The timing unit accurately measures the duration of the time slice, while the state transition unit controls the conduction path of the RF path based on the current time slice identifier, enabling rapid switching of the antenna between different modules. Through this process, under conditions of frequency domain conflict, multiple modules that originally competed for the same frequency band resources are transformed into independently operating modules in a time-sequenced manner. This effectively avoids interference problems caused by signal overlap. Simultaneously, it dynamically allocates time resources based on service requirements, enabling high-priority communication to obtain more stable transmission conditions. The technical effect is to reduce data retransmission and link instability caused by co-channel interference, improve antenna resource utilization efficiency, and ensure communication quality and user experience in multi-service concurrent scenarios.

[0038] In an optional implementation of this embodiment, the step of determining the time slice allocation ratio of each wireless communication module based on the frequency domain conflict determination result and the real-time traffic data of each wireless communication module includes: acquiring the real-time traffic data of the first wireless communication module and the second wireless communication module that have frequency domain conflicts, wherein the real-time traffic data includes uplink data volume, downlink data volume, and data packet transmission delay requirements; calculating the first traffic load value of the first wireless communication module based on the uplink and downlink data volume of the first wireless communication module, and calculating the second traffic load value of the second wireless communication module based on the uplink and downlink data volume of the second wireless communication module; determining the first delay sensitivity level and the second delay sensitivity level respectively based on the data packet transmission delay requirements of the first wireless communication module and the second wireless communication module; generating the time slice weight of the first wireless communication module and the time slice weight of the second wireless communication module through weighted calculation based on the first traffic load value, the second traffic load value, the first delay sensitivity level, and the second delay sensitivity level; and determining the time slice allocation ratio of the first wireless communication module and the time slice allocation ratio of the second wireless communication module respectively based on the proportion of the time slice weight of the first wireless communication module and the time slice weight of the second wireless communication module to the total weight.

[0039] Specifically, after determining that a frequency domain conflict exists, fine-grained resource allocation is required for the wireless communication modules involved in the conflict. First, the main control chip extracts real-time traffic data from the underlying counter registers and buffer states of each module. Uplink data volume refers to the number of data bytes sent from the device to the external network per unit time, while downlink data volume refers to the number of data bytes received from the external network per unit time. Both can be accumulated using data counters at the physical layer or link layer and converted into a rate value using a time window. Data packet transmission latency requirements are derived from the service quality parameters corresponding to the current service type. This parameter reflects the maximum allowable time interval between the data transmission and reception. For example, video projection services require continuous image quality and have a low latency threshold, while audio playback has a slightly higher tolerance for instantaneous latency but requires stability. In scenarios where wireless projection and Bluetooth audio playback occur simultaneously on the same display device, the downlink data volume of the wireless LAN module is significantly higher than the uplink data volume, while the uplink and downlink data volumes of the Bluetooth module are both relatively small. After obtaining the above data, the uplink and downlink data volumes are fused and calculated to characterize the module's channel resource occupancy intensity, forming a traffic load value. This value can be more accurately reflected by summing the uplink and downlink data volumes directly, or by introducing directional weights to strengthen the downlink proportion, thus providing a more accurate picture of the bandwidth requirements for video services. For example, in a screen mirroring scenario, if the downlink rate of the Wi-Fi module is 20Mbps and the uplink rate is 2Mbps, the traffic load value can be considered relatively high, while the traffic load value of the Bluetooth module is significantly lower when both uplink and downlink speeds are 0.5Mbps. Subsequently, a latency sensitivity level is mapped based on the latency requirements of each module. This level describes the degree to which the service depends on time continuity. The latency sensitivity level can be divided into multiple discrete intervals; for example, low latency requirements can be mapped to higher level values ​​to reflect priority in subsequent calculations. Wireless screen mirroring services, due to the need to ensure synchronization between video and audio, have a higher latency sensitivity level than Bluetooth audio playback services. After determining the traffic load value and latency sensitivity level, a time slice weight is generated through weighted calculation. In the specific implementation, the traffic load value and latency sensitivity level are combined in a calculation to consider both the data volume and the impact of latency constraints on resource allocation. For example, the traffic load value can be multiplied by the corresponding latency level coefficient to obtain a comprehensive weight value. In this weight, modules with large data volumes and modules with strict latency requirements will obtain higher results. In the case of concurrent screen mirroring and Bluetooth, the wireless LAN module, due to its simultaneous high traffic and high latency sensitivity, has a significantly higher time slice weight than the Bluetooth module. Finally, based on the proportion of each module's time slice weight in the total weight, a time slice allocation ratio is calculated to guide the occupancy time of antenna resources among different modules. For example, when the weight proportion of the wireless LAN module is 0.7 and that of the Bluetooth module is 0.3, the corresponding antenna occupancy times are 70% and 30%, respectively, thereby generating a time-division multiplexing control timing sequence that meets business requirements.Through the above processing, high-load and latency-sensitive services can obtain more continuous transmission opportunities, while ensuring that low-load services still have stable communication capabilities. The technical effect is to significantly reduce service interference under the condition of frequency domain conflict, improve the transmission continuity of key services and the spectrum utilization efficiency of the overall system.

[0040] In one optional implementation of this embodiment, when there are two wireless communication modules with frequency domain conflict, and the operating frequency bands of the two wireless communication modules are located on opposite sides of a preset separable frequency band range, the operating frequency bands of the two wireless communication modules are obtained. Based on the operating frequency bands of the two wireless communication modules, a first dedicated metal block and a second dedicated metal block are determined from other metal blocks of the display casing. The radiation efficiency of the first dedicated metal block under the operating frequency band of the first wireless communication module is higher than that under the operating frequency band of the second wireless communication module, and the radiation efficiency of the second dedicated metal block under the operating frequency band of the second wireless communication module is higher than that under the operating frequency band of the first wireless communication module. The radio frequency path of the first wireless communication module is connected to the first dedicated metal block through an antenna switch, and the radio frequency path of the second wireless communication module is connected to the second dedicated metal block, so that the first wireless communication module and the second wireless communication module can simultaneously transmit and receive signals through their respective dedicated metal blocks.

[0041] Specifically, when it is determined that there is a frequency domain conflict and the number of wireless communication modules involved in the conflict is two, the frequency distribution characteristics of the two modules are further analyzed. When the operating frequency bands of the two modules are located on opposite sides of a preset separable frequency band range, it indicates that although there is a conflict relationship between the two modules in the system-level determination, they are separable in terms of electromagnetic characteristics. The separable frequency band range refers to a frequency interval pre-defined according to the terminal structure and antenna layout. The current distribution paths and radiation modes on both sides of this interval are significantly different, thus causing metal blocks in different locations to exhibit differentiated radiation capabilities in different frequency bands. Radiation efficiency is a parameter used to measure the ability of an antenna to convert input radio frequency energy into effective electromagnetic wave radiation. The higher the value, the lower the energy loss and the better the radiation effect. In the scenario of wireless screen projection and Bluetooth audio playback on the same display device, the wireless LAN module operates in the 5.8GHz frequency band, and the short-range wireless communication module operates in the 2.4GHz frequency band. The two are located on the high-frequency side and the low-frequency side of the preset separable frequency band range, respectively. After acquiring the operating frequency bands of the two modules, the main control chip selects a suitable radiation region from multiple metal blocks separated by nano-injection molded insulating strips. Due to the differences in size, shape, and position of different metal blocks within the overall system, their current distribution paths vary across different frequency bands, resulting in higher radiation efficiency at certain frequency bands. In the specific implementation, a performance mapping relationship between metal blocks and frequency bands is pre-established. A metal block with high radiation efficiency at 5.8GHz is designated as the first dedicated metal block, while a metal block with high radiation efficiency at 2.4GHz is designated as the second dedicated metal block. For example, a shorter metal block located on the top edge of the device is more likely to form an effective resonant path at high frequencies, making it suitable for 5.8GHz signal radiation, while a longer metal block located on the side is more likely to form a complete current loop at low frequencies, making it more suitable for 2.4GHz signal radiation. This way, even if the two modules conflict at the system resource level, physical isolation at the frequency band can be achieved through spatial separation. After determining the dedicated metal blocks, the corresponding relationship of the radio frequency path is established through an antenna switch. The radio frequency (RF) path refers to the signal transmission path from the RF front-end of the wireless communication module to the antenna radiating element. This path is selectively activated by a switch matrix. The antenna switch contains multiple controllable switching units. By changing the activation state through control signals, the RF output of the first wireless communication module is connected only to the first dedicated metal block, while the RF output of the second wireless communication module is connected to the second dedicated metal block, thus forming two independent radiation paths. In the aforementioned concurrent screen projection and Bluetooth scenario, the wireless LAN module transmits and receives high-frequency signals through the first dedicated metal block, while the Bluetooth module transmits and receives low-frequency signals through the second dedicated metal block. Both can operate simultaneously without alternating switching in time.Through the above processing, the two modules that originally needed to avoid conflicts through time-division multiplexing are transformed into a spatially separated parallel working mode, so that signals of different frequency bands can propagate independently on their respective optimal radiation structures. The technical effect is to reduce resource competition caused by frequency domain conflicts, reduce the latency introduced by time-division switching, and improve the radiation efficiency and link stability of each frequency band, thereby improving the overall communication performance in scenarios with multiple concurrent wireless services.

[0042] It should be noted that the nano-injection molded insulating strip is a structure that forms electrical isolation by embedding insulating material into a metal structure. After the display shell is integrally molded from metal, the insulating strip is embedded at predetermined dividing positions using a nano-injection molding process. Specifically, grooves are machined along a designed trajectory on the inner side of the shell, and the surface is treated with nanoporous technology to form micropores of 10 to 50 nanometers. Engineering plastic is then injected into the grooves, and after the plastic cures, it forms an atomic-level bond with the metal, thus forming an insulating strip with a width of not less than 1.5 mm in the originally continuous metal shell. This insulating strip divides the shell into multiple electrically isolated metal blocks. Each metal block independently serves as a candidate unit for antenna radiators. Adjacent metal blocks are physically connected and electrically isolated only through the nano-injection molded insulating strip. At least one metal block is connected to the motherboard's RF circuit through an RF feed structure, directly serving as an antenna radiator for signal transmission and reception. This integrated structure eliminates the need for independent antenna components and their mounting structures, and the antenna does not occupy internal space in the display, which is beneficial for the overall thinness and lightness of the device. Nano-injection molded insulating strips divide the display casing into multiple independent metal blocks in different areas. These metal blocks are distributed at different locations, including the upper left, upper right, lower left, lower right, and central areas of the casing. The spatial distance between the metal blocks and interference sources inside the display varies, resulting in different electromagnetic coupling strengths to the same interference source. This provides a physical basis for interference avoidance through antenna switching. As components of the casing, the shape, size, thickness, and position coordinates of each metal block on the display casing are determined during the mechanical structure design phase and ensured to be consistent during manufacturing using molds. Therefore, the position coordinates of each metal block and its radiation efficiency data at each preset frequency band can be obtained in advance through simulation or testing and stored in a metal block information table for system retrieval, providing accurate parameters without real-time calibration. The remaining metal blocks not used as antennas serve as the system ground plane, with electrical isolation between the antenna radiator and the ground plane achieved through nano-injection molded insulating strips. When the radio frequency (RF) path switches from the first metal block to the second metal block, the spatial orientation of the antenna radiator relative to the ground plane changes, thereby altering the antenna's radiation pattern and polarization characteristics. Different radiation modes are selected based on communication requirements. Furthermore, multiple metal blocks are distributed at different locations within the casing, and each metal block is at a different spatial distance from the interference source. When harmonic interference is detected, the RF path is switched from the first metal block (closer to the interference source) to the second metal block (farther from the interference source) by switching the connection object, directly changing the antenna radiator's position in space and achieving active spatial avoidance of the interference source. Simultaneously, different metal blocks exhibit varying radiation efficiencies within the same interference frequency band. Metal blocks with lower radiation efficiency in the interference frequency band can be selected to further reduce interference coupling at the frequency domain level.

[0043] According to the integrated signal transceiver control method for display housing antenna provided in this application, multiple metal blocks formed by nano-injection molding are used as dynamically switchable antenna resources. When harmonic interference is detected from an interference source, the method can select a metal block that is far away from the interference source and has low radiation efficiency in the interference frequency band from the multiple metal blocks on the housing and switch it to actively avoid the interference source, thereby ensuring the quality of signal transmission and reception.

The switching module 50 is used to switch the connection object with the motherboard RF circuit from the first metal block to the second metal block, and to use the second metal block as the second antenna radiation area for signal transmission and reception.

[0047] In one optional implementation of this embodiment, the switching module is specifically used to: compare the first radiation efficiency data of the first metal block under the target interference frequency band with the second radiation efficiency data of the second metal block under the target interference frequency band to generate a radiation efficiency change; when the radiation efficiency change is greater than a preset change threshold, adjust the radio frequency transmission power from a first power value to a second power value, where the first power value is the radio frequency transmission power before switching and the second power value is the temporary transmission power during switching; based on the second power value, switch the connection object with the motherboard radio frequency circuit from the first metal block to the second metal block; after the switching is completed, restore the radio frequency transmission power from the second power value to the first power value, and use the second metal block as the second antenna radiation area for signal transmission and reception.

[0048] In an optional embodiment of this example, the switching module is further configured to: determine the radiation efficiency ratio between the first radiation efficiency data and the second radiation efficiency data; obtain the received signal strength indication value of the current signal transceiver link, and determine the link quality level of the current signal transceiver link based on the received signal strength indication value; query the corresponding power adjustment coefficient from a preset power adjustment mapping table based on the radiation efficiency ratio and the link quality level, wherein the power adjustment mapping table includes several radiation efficiency ratio intervals, several link quality levels, and power adjustment coefficients corresponding to each radiation efficiency ratio interval and each link quality level; and generate a second power value based on the first power value and the power adjustment coefficient.
