Description

Technical Field

[0001] This application relates to the field of performance testing technology, and in particular to a method and system for rectifying interference paths in a display device. Background Technology

[0002] In the research and development and production of display products, the corresponding wireless performance testing is a crucial basis for evaluating the wireless performance of these products; one aspect of this wireless performance testing is OTA (Over-The-Air) testing. Therefore, each model of display product needs continuous improvements during the OTA testing process to meet the required specifications.

[0003] Typically, display products experience high-frequency signal leakage during operation, affecting the accuracy of OTA testing. Therefore, current OTA testing for display products requires removing the product from the anechoic chamber after each test, making adjustments based on the test results, and then moving it back into the anechoic chamber for another OTA test. This results in the product being moved in and out of the anechoic chamber multiple times during OTA testing, consuming a significant amount of time. In summary, current OTA testing for display products suffers from low efficiency. Summary of the Invention

[0041] When the display device under test is in a test-ready state after being powered on, the power to the display device under test is turned off, and the spectrum analyzer is driven to acquire the first interference data of the antenna assembly of the display device under test; the test-ready state indicates that the wireless communication module in the display device under test is in a non-signaling receiving mode.

[0046] The interference path rectification method, system, apparatus, computer equipment, storage medium, and computer program product for display devices provided in this application are described above. The interference path rectification method for display devices is applied to a control device in the interference path rectification system for display devices. The system also includes a display device under test (DUT) and a spectrum analyzer. The antenna assembly of the DUT is electrically connected to the spectrum analyzer, and the control device is communicatively connected to both the DUT and the spectrum analyzer. First, when the DUT is powered on and in a test-ready state, the control device controls the DUT to power off and drives the spectrum analyzer to acquire the first interference data of the DUT's antenna assembly. The test-ready state indicates that the wireless communication module in the DUT is in a non-signaling receiving mode. Then, the control device... The device under test (DUT) is powered on, and the control device controls at least one potential interference source of the DUT to be in an active state, thereby driving the spectrum analyzer to acquire second interference data of the antenna assembly. Next, the control device controls at least one potential interference source of the DUT to be disconnected from the active state, and drives the spectrum analyzer to acquire third interference data of the antenna assembly. Then, based on the comparison results of the first interference data, the second interference data, the third interference data, and the pre-acquired air interface performance test data of the DUT, the control device determines at least one of the potential interference sources as the target interference source. Finally, the control device determines corresponding preset rectification measures based on the target interference source, and rectifyes the interference path between the target interference source and the antenna assembly based on the preset rectification measures. In the above process, when the wireless communication module in the display device under test is in the non-signaling receiving mode, the power to the display device is turned off by the control device, so that the spectrum analyzer can obtain the first interference data of the antenna assembly of the display device under test under the condition of no internal component interference, as a control group; then, the power to the display device under test is turned on, and at least one interference source to be identified in the display device under test is controlled to be in the working state and the disconnected working state, so that the spectrum analyzer can obtain the second interference data corresponding to at least one interference source in the antenna assembly when it is working, and the third interference data corresponding to at least one interference source in the antenna assembly when it is not working; the three sets of interference data (first interference data, second interference data and third interference data) measured by the spectrum analyzer can provide data support for the subsequent determination of the target interference source, and the spectrum analyzer can obtain more accurate interference data, thereby improving the accuracy of the target interference source determination. Furthermore, after identifying the target interference source, corresponding rectification measures can be taken to rectify the interference path between the target interference source and the antenna components, thereby reducing or eliminating the interference signal and optimizing the wireless performance of the display device under test. Moreover, by using the interference path rectification method for display devices provided in this application, it is not necessary to move the display device under test in and out of the non-reflective anechoic chamber multiple times, saving resources and time while also improving the efficiency of OTA testing for display products.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0052] Figure 5 This is an internal structural diagram of a computer device in one embodiment. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] Taking interactive large-panel products in the display category as an example, one of the testing methods used to evaluate their wireless performance indicators in related technologies is OTA testing. The testing process is as follows: First, the assembled and normally functioning complete unit (the display device under test) is placed in a prepared non-reflective, fully anechoic chamber. There is a ring of test probes in the chamber, and each probe communicates with the complete unit to measure the signal transmission and reception data of the complete unit at the angle of the test probe. Then, the turntable under the complete unit will rotate from a fixed angle of 0° to 180°. Every time the complete unit rotates by an angle, the test probes in the ring will communicate in sequence to measure the communication data of each angle of the 360° sphere of the complete unit. Then, the TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity) of the complete unit are calculated by an algorithm on a computer to determine the quality of the radio frequency link of the complete unit.

[0055] However, in practical applications, each model of the complete unit needs to undergo OTA testing, and the test results must meet preset specifications. Therefore, multiple modifications to the complete unit are required during the testing process, especially for the receiver sensitivity (TIS) data. Furthermore, during operation, a significant amount of high-frequency signal leakage occurs from high-speed signals such as screen signals, memory chips, main chips, USB (Universal Serial Bus), and PCIe (Peripheral Component Interconnect Express). These signals, or their multipliers, are received by the antenna components, thus reducing the TIS value. Therefore, multiple modifications to the complete unit are necessary to obtain relatively accurate TIS data for judging the quality of the RF link. Therefore, it is necessary to analyze different system problems and test solutions before conducting system testing in a reflection-free anechoic chamber. During this process, each test requires queuing, disassembling, testing, and reassembling the system, and then transporting it into the laboratory to be mounted on the test rack. Testing a single channel takes more than ten minutes, and moving the equipment up and down takes at least half an hour. This not only wastes laboratory resources but also human and financial resources, and seriously reduces the efficiency of OTA testing of the system, thus delaying the R&D progress.

[0056] In summary, there is currently a problem of low OTA testing efficiency for display products. Therefore, it is necessary to provide a method for rectifying interference paths in display devices to address this technical issue. This embodiment uses the application of this method to a control device in an interference path rectification system for a display device as an example. It is understood that this method can also be applied to terminals or servers, and can also be applied to systems including terminals and servers, implemented through interaction between the terminal and the server.

[0057] like Figure 1 As shown, the interference path rectification system 100 provided in this application includes, in addition to the control device 101, a display device under test 102 and a spectrum analyzer 103. The antenna assembly 104 of the display device under test 102 is electrically connected to the spectrum analyzer 103 so that the signal received by the antenna assembly 104 can be detected based on the spectrum analyzer 103. The control device 101 is communicatively connected to the display device under test 102 and the spectrum analyzer 103 so that the control device 101 can control the working state of the display device under test 102 and / or some of its components, and control the signal detection operation of the spectrum analyzer 103.

[0058] In one exemplary embodiment, such as Figure 2 As shown, the interference path rectification method provided in this application includes the following steps:

[0059] Step S202: When the display device under test is in a test state after being powered on, the power to the display device under test is turned off, and the spectrum analyzer is driven to acquire the first interference data of the antenna assembly of the display device under test; the test state indicates that the wireless communication module in the display device under test is in a non-signaling receiving mode.

[0060] The device under test (DUT) refers to the device being tested, typically a device used to display information. The DUT provided in this application is equipped with an antenna assembly to enable wireless data transmission between the DUT and external devices.

[0061] Powering on means connecting the display device under test (DUT) to a power source, enabling it to be used normally when required. The state under test refers to the DUT being in a state where it only receives signals and does not transmit signals, i.e., the non-signaling receiving mode described above.

[0062] Here, a spectrum analyzer refers to an instrument that measures the frequency distribution of a signal and can be used to analyze the spectral characteristics of wireless signals. The first interference data refers to data acquired by the spectrum analyzer when the display device under test is powered off, unaffected by any interference sources within the display device. The wireless communication module refers to the component that performs wireless data transmission.

[0063] Optionally, the display device under test can be an interactive whiteboard, a conference screen, a mobile phone, a tablet computer, or other types of display panels; the wireless communication module can be a WiFi (Wireless Local Area Network) module for connecting to a wireless local area network; it can also be a BT (Bluetooth) module for short-range wireless communication, device pairing, and data transmission; or it can be a cellular 2G / 3G / 4G / 5G module for data transmission, etc. This application does not make any specific limitations on this.

[0064] Step S204: Power on the display device under test and control at least one interference source to be identified in the display device under test to be in working state, so as to drive the spectrum analyzer to acquire the second interference data of the antenna assembly.

[0065] The term "interference source to be identified" refers to any interference source that affects the normal transmission and reception of wireless signals by the antenna components in the display device under test (DUT). This can be any component in the DUT that interferes with the wireless communication of the antenna components. "Operating state" refers to the DUT being in operation. The high-frequency signals emitted by the DUT in this operating state may adversely affect the wireless communication of the antenna components in the DUT. "Secondary interference data" refers to the signal data received by the antenna components captured by the spectrum analyzer when the DUT is in operation. This data reflects the interference generated by the DUT on the antenna components of the DUT during operation.

[0066] Step S206: Control at least one interference source to be identified in the display device under test to be disconnected from the working state, and drive the spectrum analyzer to acquire the third interference data of the antenna assembly.

[0067] The "disconnected working state" refers to the state in which the interference source to be identified is in a stopped state and does not emit wireless signals that would adversely affect the display device under test. The third interference data refers to the signal data received by the antenna assembly captured by the spectrum analyzer when the interference source to be tested is in the disconnected working state. This data can be used to reflect the interference generated by the interference source to be tested on the antenna assembly of the display device under test when it is not working.

[0068] Step S208: Based on the comparison results of the first interference data, the second interference data, the third interference data and the pre-acquired air interface performance test data of the display device under test, at least one of the interference sources to be determined is identified as the target interference source.

[0069] The air interface performance test data refers to the OTA test data obtained after performing an OTA test on the display device under test. This data is acquired before the display device under test is powered on; that is, before performing step 202 provided in this application, the display device under test can be subjected to at least one OTA test. The target interference source refers to the interference source determined by analyzing the first interference data, the second interference data, the third interference data, and the air interface performance test data. The target interference source may include at least one interference source that has a significant impact on the performance of the display device under test, and is usually determined based on the signal frequency and signal strength of the first interference data, the second interference data, the third interference data, and the air interface performance test data.

[0070] It should be added that, since the signal frequency and / or signal strength of the interference signals generated by different devices or components in the display device under test are different during operation, the target interference source can be accurately determined based on the signal frequency and signal strength of the first interference data, second interference data, third interference data and air interface performance test data obtained above.

[0071] Step S210: Determine the corresponding preset rectification measures based on the target interference source, and rectify the interference path between the target interference source and the antenna assembly based on the preset rectification measures.

[0072] Among them, the pre-set rectification measures refer to a series of rectification plans set in advance for the identified target interference source; rectification refers to the process of improving the wireless communication effect of the display device under test; interference path refers to the path through which the target interference source transmits interference signals to the antenna component; wireless performance refers to the performance of the display device under test in wireless communication, which may include signal transmission quality, signal connection speed, and signal delay rate, etc.

[0073] As an example, the pre-set rectification measures can be to adjust and correct the interference path through which the target interference source transmits interference signals to the antenna assembly, so as to reduce or eliminate the interference signals on the interference path. This includes measures such as line optimization, line shielding, and strengthening the stability of the surrounding ground. Alternatively, it can be to isolate the target interference source and the antenna assembly, including measures such as setting up isolation components and shielding components.

[0074] It should be added that before performing step 202 provided in this application, it is necessary to ensure that there are no other interference sources outside the display device under test, so as to ensure the accuracy of the determination of the interference sources inside the display device under test.

[0075] The aforementioned interference path rectification method for display devices is applied to the control device in an interference path rectification system for display devices. The system also includes a display device under test (DUT) and a spectrum analyzer. The antenna assembly of the DUT is electrically connected to the spectrum analyzer, and the control device is communicatively connected to both the DUT and the spectrum analyzer. First, when the DUT is powered on and in a test-ready state, the control device powers off the DUT and drives the spectrum analyzer to acquire the first interference data from the DUT's antenna assembly. The test-ready state indicates that the wireless communication module in the DUT is in a non-signaling receiving mode. Then, the control device powers on the DUT and controls the DUT to... At least one interference source to be identified is put into operation to drive the spectrum analyzer to acquire second interference data of the antenna assembly; then, the control device controls at least one interference source to be identified in the display device under test to be disconnected from operation and drives the spectrum analyzer to acquire third interference data of the antenna assembly; then, based on the comparison results of the first interference data, the second interference data, the third interference data and the pre-acquired air interface performance test data of the display device under test, the control device determines at least one of the interference sources to be identified as the target interference source; finally, the control device determines the corresponding preset rectification measures based on the target interference source, so as to rectify the interference path between the target interference source and the antenna assembly based on the preset rectification measures. In the above process, when the wireless communication module in the display device under test is in the non-signaling receiving mode, the power to the display device is turned off by the control device, so that the spectrum analyzer can obtain the first interference data of the antenna assembly of the display device under test under the condition of no internal component interference, as a control group; then, the power to the display device under test is turned on, and at least one interference source to be identified in the display device under test is controlled to be in the working state and the disconnected working state, so that the spectrum analyzer can obtain the second interference data corresponding to at least one interference source in the antenna assembly when it is working, and the third interference data corresponding to at least one interference source in the antenna assembly when it is not working; the three sets of interference data (first interference data, second interference data and third interference data) measured by the spectrum analyzer can provide data support for the subsequent determination of the target interference source, and the spectrum analyzer can obtain more accurate interference data, thereby improving the accuracy of the target interference source determination. Furthermore, after identifying the target interference source, corresponding rectification measures can be taken to rectify the interference path between the target interference source and the antenna components, thereby reducing or eliminating the interference signal and optimizing the wireless performance of the display device under test. Moreover, by using the interference path rectification method for display devices provided in this application, it is not necessary to move the display device under test in and out of the non-reflective anechoic chamber multiple times, saving resources and time while also improving the efficiency of OTA testing for display products.

[0076] In an exemplary embodiment, step S204, which controls the display device under test (DUT) to power on and controls at least one unidentified interference source of the DUT to be in an active state, to drive the spectrum analyzer to acquire second interference data of the antenna assembly, includes: driving the spectrum analyzer to acquire second interference data of the antenna assembly when the PCIe interface of the DUT is in an active state. Step S206, which controls at least one unidentified interference source of the DUT to be deactivated and drives the spectrum analyzer to acquire third interference data of the antenna assembly, includes: driving the spectrum analyzer to acquire third interference data of the antenna assembly when the PCIe interface of the DUT is deactivated.

[0077] The PCIe (Peripheral Component Interconnect Express) interface refers to a high-speed interface, such as versions 1.0 and 2.0, typically used for connecting hardware. A PCIe interface in a working state indicates that a hardware device is connected to it. When a hardware device is connected and operating, the PCIe interface and its connecting cables generate high-frequency signals. These high-frequency signals may interfere with the antenna assembly of the display device under test. This interference signal is detected by the spectrum analyzer and is the second interference data mentioned above. A PCIe interface in a disconnected state indicates that the hardware device is disconnected. In this state, the spectrum analyzer can re-detect the interference signal received by the antenna assembly of the display device under test, and the detected data is the third interference data mentioned above.

[0078] It should be noted that the target interference source for the display device under test may be singular in some cases, such as the PCIe interface being the only interference source. As an example, when the PCIe interface and protocol traces of the display device under test are in operation under protocols version 1.0 and 2.0, the clock signal frequencies are 1.25GHz and 2.5GHz respectively. These frequencies, or their multipliers, will directly interfere with the WiFi frequency band; therefore, the interference data generated when the PCIe interface is in operation is the aforementioned second interference data.

[0079] In this embodiment, by acquiring the second interference data generated by the PCIe interface on the antenna assembly when the PCIe interface is in the working state, and the third interference data generated by the PCIe interface on the antenna assembly when the PCIe interface is in the disconnected working state, data support can be provided for subsequent determination of the target interference source, thereby improving the accuracy of the target interference source determination.

[0080] In one embodiment, step S204, which controls the display device under test (DUT) to power on and controls at least one unidentified interference source of the DUT to be in an active state, to drive the spectrum analyzer to acquire second interference data of the antenna assembly, includes: driving the spectrum analyzer to acquire second interference data of the antenna assembly when the HDMI interface of the DUT is in an active state. Step S206, which controls at least one unidentified interference source of the DUT to be deactivated and drives the spectrum analyzer to acquire third interference data of the antenna assembly, includes: driving the spectrum analyzer to acquire third interference data of the antenna assembly when the HDMI interface of the DUT is deactivated.

[0081] HDMI (High Definition Multimedia Interface) refers to an audio and video transmission interface; it is a fully digital video and audio transmission interface that can send uncompressed audio and video signals. HDMI interfaces can be used to connect devices such as graphics cards and speakers. An HDMI interface being active indicates that a device is connected and transmitting audio and video signals. For example, when an HDMI interface is used to transmit a video signal at a certain resolution, the HDMI interface and its connecting cable will generate high-frequency signals. These high-frequency signals may interfere with the antenna components of the display device under test. This interference signal is detected by a spectrum analyzer and is the second type of interference data mentioned above. An HDMI interface being disconnected indicates that the HDMI interface is not connected to other devices and is not used to transmit audio and video signals. In this state, the spectrum analyzer can re-detect the interference signals received by the antenna components of the display device under test, and the data detected in this state is the third type of interference data mentioned above.

[0082] It should be noted that the target interference source for the display device under test can be singular in some cases, such as the HDMI interface being the only interference source. As an example, the HDMI interface in the display device under test can be used to connect external cables for audio and video transmission interfaces such as hard drives, graphics cards, and sound cards. When transmitting signals of different resolutions, the transmission rate and clock frequency of the signal lines are different. For example, under the HDMI 2.0 protocol, the maximum transmission rate is 18Gbps (gigabits per second). In this state, the TMDS (Transition Minimized Differential Signaling) clock is 600MHz (megahertz), and its fourth harmonic is 2.4GHz (gigahertz). WiFi typically operates in the 2.4GHz and 5GHz frequency bands, which overlap with the 2.4GHz WiFi band, causing significant interference. Therefore, the interference data generated when the HDMI interface is in operation is the second type of interference data mentioned above.

[0083] In addition, other HDMI features such as CEC (Consumer Electronics Control) also affect the detected second or third interference data. CEC refers to allowing devices connected via HDMI to control each other, such as using one remote control to control multiple HDMI-connected TVs or Blu-ray players. Therefore, the above interference can be reduced by disabling the CEC function, testing by plugging and unplugging the HDMI cable, replacing it with a certified high-shield transmission cable, and strengthening grounding by wrapping the HDMI connector area and circuit area with conductive copper foil.

[0084] Furthermore, if the wireless performance of the device still does not meet the optimization target after using preset rectification measures to rectify the interference path between the target interference source and the antenna components, the target interference source can also be rectified, such as replacing the screen, camera, etc. in the device that generate interference data, thereby reducing interference data from the source.

[0085] In this embodiment, by acquiring the second interference data generated by the HDMI interface on the antenna assembly when the HDMI interface is in working state, and the third interference data generated by the HDMI interface on the antenna assembly when the HDMI interface is disconnected, data support can be provided for subsequent determination of the target interference source, thereby improving the accuracy of the target interference source determination.

[0086] Furthermore, in one embodiment, the step S202, in which the display device under test is in a test-ready state after being powered on, includes: when the display device under test is powered on, unloading the driver corresponding to the wireless communication module in the display device under test, and after installing the non-signaling debugging driver and software on the display device under test, restarting the display device under test; configuring the wireless communication module of the restarted display device under test to a non-signaling receiving mode, so that the display device under test is in a test-ready state.

[0087] The wireless communication module can include a WiFi module, a Bluetooth module, and a cellular 2G / 3G / 4G / 5G module. The driver for the WiFi module is a WiFi driver, the driver for the Bluetooth module is a Bluetooth driver, and the driver for the cellular 2G / 3G / 4G / 5G module is a cellular driver. The non-signaling debugging driver and software can be software and drivers designed for debugging purposes, allowing the display under test (DUT) to receive signals in a non-signaling state. This is usually used to analyze and test the performance of the DUT without interfering with its normal data communication. The non-signaling receiving mode refers to the wireless communication module not sending signals but maintaining sensitivity to received signals. The state under test can refer to determining that the data scanned by the spectrum analyzer is not an interference signal emitted by the communication equipment, but an interference signal emitted by an internal interference source of the DUT.

[0088] In this embodiment, by uninstalling the driver of the wireless communication module and installing the non-signaling debugging driver and software, the interference of the current driver on the testing process can be eliminated, ensuring the accuracy of the test data; in the non-signaling mode, the display device under test can obtain more accurate interference and signal data.

[0089] In one embodiment, before the display device under test is powered on in step S202, the method further includes: acquiring air interface performance test data of the display device under test in both working and disconnected states in response to at least one interference source to be determined.

[0090] The operating status of the interference source to be determined may include the power module of the display device under test being in an operating state or not, the display screen being in an operating state or not, the USB interface being in an operating state or not, the camera being in an operating state or not, the PCIe interface being in an operating state or not, and the HDMI interface being in an operating state or not.

[0091] As an example, before powering on the display device under test, air interface performance test data can be selectively acquired, at least when the power module of the display device under test is in a working state, and air interface performance test data when the power module of the display device under test is in a de-energized state, as pre-acquired air interface performance test data of the display device under test.

[0092] As another example, before the display device under test is powered on, air interface performance test data can be selectively acquired, at least when the display screen of the display device under test is in a working state, and air interface performance test data when the display screen of the display device under test is in a disconnected working state, as pre-acquired air interface performance test data of the display device under test.

[0093] As another example, before the display device under test is powered on, air interface performance test data can be specifically acquired when the USB interface of the display device under test is in a working state, and air interface performance test data when the USB interface of the display device under test is in a disconnected working state, as the air interface performance test data of the display device under test acquired in advance.

[0094] As another example, before the display device under test is powered on, at least the air interface performance test data of the display device under test when the camera is in working state and the air interface performance test data of the display device under test when the camera is in a disconnected working state can be specifically acquired as the air interface performance test data of the display device under test acquired in advance.

[0095] In the above embodiments, by acquiring the air interface performance test data of the display device under test in both working and disconnected states for a target interference source, data support can be provided for the subsequent determination of the target interference source, thereby improving the efficiency and accuracy of the target interference source determination.

[0096] However, this application does not limit itself to acquiring air interface performance test data for only one type of component under different operating conditions in a single OTA test, but can also acquire air interface performance test data for multiple components under different operating conditions.

[0097] More specifically, in one embodiment, the interference path rectification method for the display device further includes: acquiring updated air interface performance test data obtained by performing another air interface performance test on the display device under test after optimizing its wireless performance; generating a rectification completion prompt message if the updated air interface performance test data represents the rectification result of the preset rectification measures and meets the preset indicators of the display device under test; and driving the spectrum analyzer to acquire the first interference data, second interference data, and third interference data of the antenna assembly again to rectify the interference path between the target interference source and the antenna assembly again.

[0098] The updated air interface performance test data refers to the air interface performance test data detected again by OTA after the identified target interference sources have been rectified. The preset rectification measures refer to the corresponding measures for each target interference source to reduce or eliminate the interference of the target interference source on the antenna components of the display device under test. The prompt information may be in the form of a pop-up window displaying "rectification completed" or similar words controlled by the control equipment on the display device under test, or the control equipment controlling the display device under test to light up a green light, etc. The preset indicators may include signal strength, signal quality, radiated power, etc.

[0099] As an example, the preset target is an average signal bandwidth of 110dB within the 2.4GHz band. After turning on the display device under test, the signal bandwidth was found to rise to -90dB, indicating that the rectification results do not meet the preset target of the display device under test and there is 20dB of interference signal. It is necessary to obtain the first, second, and third interference data of the antenna components of the display device under test again. By relocating the components and frequencies corresponding to the target interference source, the display device under test needs to be rectified again. For example, the 2.4GHz frequency may be due to radiation from the USB 3.0 signal line, which requires measures such as line optimization, line shielding, strengthening the stability of the surrounding ground, or isolating the path of the antenna components and the target interference source. The specific preset rectification measures selected are related to the comprehensive consideration of various factors such as structure, chip, software, cost, and mass production.

[0100] In this embodiment, by conducting another air interface performance test, the effectiveness of the preset rectification measures can be accurately evaluated, ensuring that the wireless performance of the display device under test is truly improved. If the updated test data does not meet the preset indicators, the target interference source is relocated and rectified, which helps to identify problems in the display device under test in a timely manner; through the implementation of multiple rectifications, the wireless communication quality of the display device under test can be continuously improved.

[0101] In one exemplary embodiment, the air interface performance test is performed in a reflection-free anechoic chamber, and the process of determining the target interference source of the display device under test is performed in a shielded room.

[0102] Among them, the non-reflective anechoic chamber is a static electromagnetic environment covered with absorbing materials, which can be used to absorb the reflection and interference of wireless signals. Air interface performance testing in the non-reflective anechoic chamber can obtain the performance data of the antenna components of the display device under test without being affected by environmental interference. The shielded room is a test environment that can effectively block external electromagnetic interference, and can focus only on the changes in interference signals caused by the internal components of the display device under test during the test.

[0103] In addition, the construction and maintenance costs of a non-reflective anechoic chamber are relatively high, and it requires a large space to accommodate the internal concave structure and absorbing materials; the overall construction and maintenance costs of a shielded room are usually lower than those of a non-reflective anechoic chamber, making it more cost-effective.

[0104] In this embodiment, the use of a non-reflective anechoic chamber and a shielded room provides an ideal environment for air interface performance testing of the display device under test and for locating the target interference source, respectively. This ensures the accuracy of the air interface performance test results and the target interference source location results, thereby improving the accuracy of the interference path rectification results of the display device under test.

[0105] In one embodiment, before the display device under test is powered on in step S202, the method further includes: controlling the wireless communication module in the display device under test to disconnect from the antenna assembly, and controlling the antenna assembly to connect to the spectrum analyzer.

[0106] By disconnecting the wireless communication module from the antenna assembly, the spectrum analyzer can acquire only the interference inside the display device under test, unaffected by the signals emitted by the wireless communication module. This improves the accuracy of the data acquired by the spectrum analyzer and lays a solid foundation for subsequent interference path rectification of the display device under test.

[0107] After disconnecting the wireless communication module from the antenna assembly, the antenna assembly can be electrically connected to the spectrum analyzer via a coaxial cable.

[0108] In another embodiment, as described above, the interference source to be determined may further include: the power module, display screen, USB interface, and camera of the display device under test; specifically, the power module of the display device under test being in a working state or a disconnected state, the display screen being in a working state or a disconnected state, the USB interface being in a working state or a disconnected state, and the camera being in a working state or a disconnected state.

[0109] Among them, "power module of the display device under test is in working state or disconnected working state" means that the device under test is powered on or off; "display is in working state or disconnected working state" means that the display is on or off; "USB interface is in working state or disconnected working state" means that the USB interface is connected to a device or not connected to a device.

[0110] In this embodiment, by acquiring the working status of each interference source to be determined and the corresponding interference data, the fault range of the display device under test can be narrowed, and the efficiency of rectifying the interference path of the display device under test can be improved.

[0111] This application provides a method for rectifying interference paths in a display device. To better understand the process of the above-described method for rectifying interference paths in a display device, combined with... Figure 3 As shown below, the specific process of an interference path rectification method for a display device according to this application is described in detail, including the following steps:

[0112] Step S302: Prepare an OTA test prototype, perform OTA tests on and off the screen of the test prototype respectively, and record the results.

[0113] Among them, the test prototype corresponds to the display device under test; the on / off state of the test prototype corresponds to the working state and the off state of the interference source to be determined; the recorded results correspond to the air interface performance test data of the display device under test that were obtained in advance.

[0114] Step S304: Place the tested prototype under the rapid rectification test topology in the shielded room.

[0115] Among them, the rapid rectification test topology corresponds to the interference path rectification system of the display device.

[0116] Step S306: Remove the antenna assembly from the device and disconnect the antenna assembly from the wireless communication module.

[0117] The complete unit corresponds to the display device under test. If the antenna assembly includes antenna matching, the connection between the antenna matching and the wireless communication module also needs to be disconnected. Then, weld a long coaxial cable to one end of the antenna assembly at the disconnection point and pull it outside the complete unit. Then, reinstall the antenna assembly into the complete unit and do not power it on.

[0118] Step S308: Connect the antenna assembly to the input port of the spectrum analyzer and turn on the spectrum analyzer.

[0119] Specifically, after turning on the spectrum analyzer, configure the frequency band, RBW (Resolution Bandwidth), etc.

[0120] Step S310: Switch the relevant equipment to flight mode and remove the relevant equipment that causes the spectrum change of the spectrum analyzer from the shielded room until the spectrum components of the spectrum analyzer disappear.

[0121] Specifically, the relevant devices can be mobile phones, computers, etc.; putting the relevant devices into airplane mode can be done by turning off cellular, WiFi, or Bluetooth, and then observing whether there are any spectrum changes in the spectrum analyzer.

[0122] Step S312: Power on the entire machine and perform a series of operations to ensure that the spectrum scanned by the spectrum analyzer is only the spectrum related to the internal components of the entire machine.

[0123] Specifically, a series of operations include uninstalling the WiFi driver, installing the non-signaling debugging driver and software, restarting the entire machine, turning off the AP / BT, configuring the WiFi in non-signaling RX mode (Receive Mode), and ensuring that the spectrum scanned by the spectrum analyzer is not the transmission spectrum emitted by the communication equipment searching for the network.

[0124] Step S314: Power off the entire machine and record a set of data curves on the spectrum analyzer; power on the machine and turn on the screen, then record another set of curves; power on the machine and turn off the screen, then record yet another set of curves.

[0125] The process involves powering off the entire device and recording a set of data curves on a spectrum analyzer. These curves correspond to the first interference data, which is equivalent to the limit curve when the device is free of interference. After powering on and turning on the screen, another set of curves is recorded, corresponding to the second interference data when the device under test is in working condition. After powering on and turning off the screen, yet another set of curves is recorded, corresponding to the third interference data when the device under test is in a deactivated state.

[0126] Step S316: Based on the above three curves and the recorded results of step S302, determine the target interference source and rectify the entire machine.

[0127] Specifically, based on the first interference data, the second interference data, the third interference data, and the pre-acquired air interface performance test data, the entire machine is rectified. During the rectification process, it is possible to observe which rectification measures are more effective. Furthermore, all rectification measures can be used together, and subsequent OTA tests can be performed by subtracting from the observed sensitive points.

[0128] Step S318: After rectification, perform OTA testing on the entire machine again.

[0129] If the updated air interface performance data obtained after re-performing the OTA test meets the preset indicators, it indicates that the entire device rectification is complete, and a rectification completion prompt message is generated. If the updated air interface performance data obtained after re-performing the OTA test does not meet the preset indicators, steps S314 to S318 are executed again to optimize the wireless performance of the display device under test until the entire device rectification is complete, and a rectification completion prompt message is generated.

[0130] Through the above embodiments, the above process can directly detect the degree of interference received by the antenna components under different overall machine operating states, thereby quickly identifying and locating the target interference source; it can also directly verify the effectiveness of the rectification measures without having to conduct OTA laboratory tests repeatedly; in addition, the test is unidirectional, without any signaling connection, and various wireless transmission protocols can be rectified using this solution, not limited to WiFi, BT, cellular 2G / 3G / 4G / 5G, etc.; and it directly reduces the original investment of a large amount of financial, human and time resources required for a single verification by about 50%.

[0131] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0132] Based on the same inventive concept, and referring to Figure 1 This application also provides an interference path rectification system for a display device to implement the interference path rectification method of the display device described above. The interference path rectification system 100 includes a display device under test 102, a spectrum analyzer 103, and a control device 101. The antenna assembly of the display device under test is electrically connected to the spectrum analyzer, and the control device is communicatively connected to both the display device under test and the spectrum analyzer. The control device is used to control the display device under test to power off when it is in a test-ready state after being powered on, and to drive the spectrum analyzer to acquire the first interference data of the antenna assembly of the display device under test. The test-ready state indicates that the wireless communication module in the display device under test is in a non-signaling receiving mode. The method involves: powering on the display device under test (DUT) and controlling at least one potential interference source of the DUT to be in an operational state, thereby driving the spectrum analyzer to acquire second interference data of the antenna assembly; disabling at least one potential interference source of the DUT and driving the spectrum analyzer to acquire third interference data of the antenna assembly; determining at least one of the potential interference sources as the target interference source based on the comparison results of the first interference data, the second interference data, the third interference data, and the pre-acquired air interface performance test data of the DUT; and determining corresponding preset rectification measures based on the target interference source to rectify the interference path between the target interference source and the antenna assembly based on the preset rectification measures.
