[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0062] The embodiments of the present application provide a test method, device, storage medium and computer device for a display device.

[0064] For example, see Figure 1 , Figure 1 A schematic diagram of a testing system for a display device provided in an embodiment of the present application. Figure 1 The test system shown may include a test device 101 , a display device 102 , a test stand 103 , and a camera 104 .

[0065] The test device 101 and the display device 102 may be connected via a communication device, the test device 101 and the camera 104 may be connected via a communication device, and the camera 104 may be fixedly connected to the test bracket 103 .

[0066] The communication device may be used for data transmission, for example, the communication device may include a USB serial port communication device, etc.

[0067] The test bracket 103 may be used to fix the display device 102 .

[0068] The test device 101 may be used to output a test signal to the display device 102; receive a target image captured by the display screen of the display device 102 and transmitted by the camera 104, perform image recognition on the target image, and determine a target re-display rate of the test image on the display device 102 based on the image recognition result.

[0070] The camera 104 may be used to capture a target image on the display screen when the display screen of the display device displays a test image.

[0071] For further information, see Figure 2 , Figure 2 A schematic diagram of an application scenario of a test stand provided in an embodiment of the present application. Figure 2 The test bracket 103 shown may be a quadrilateral rectangular frame, which supports telescoping and can be applicable to display devices of different sizes.

[0072] A buckle 1031 is provided on each side of the test bracket 103 , and the buckle 1031 can fix the test bracket 103 to the display device.

[0073] Wherein, a camera 104 is fixedly connected to each side of the test bracket 103 .

[0074] Based on the above problems, the embodiments of the present application provide a display device testing method, device, computer-readable storage medium and computer device, which can improve the display device re-display rate testing efficiency. The following are detailed descriptions. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0075] See also Figure 3 , Figure 3 A flow chart of a method for testing a display device provided in an embodiment of the present application. Taking the display device testing method applied to a terminal as an example, the terminal may be a testing device, and the specific flow of the display device testing method may be as follows:

[0076] 101. Output a test signal to a display device, so that the display device displays a test image corresponding to the test signal.

[0077] In the embodiment of the present application, the display device refers to a display device that needs to be tested and debugged for a refresh rate. The display device may include multiple types. For example, the display device may include a television, etc.

[0078] The test signal refers to a signal carrying a test image. The test image refers to an image used to perform a reproducibility test on a display device.

[0079] For example, the method of testing the re-display rate of a display device by means of a test image may include: if the display screen of the display device can display the test image exactly 100%, then it can be determined that the re-display rate of the display device is 100% at this time; if the display screen of the display device does not display the test image 100%, for example, only 95% of the content of the test image is displayed, then it can be determined that the re-display rate of the display device is 95% at this time.

[0080] Specifically, the test device may output a test signal to the display device through a communication device (such as a USB serial port data cable), and the display device may display a test image after receiving the test signal.

[0081] In some embodiments, in order to ensure the accuracy of the test results, before outputting the test signal to the display device, the test bracket can be adjusted to a size that matches the display screen of the display device, and the display device can be fixed with a buckle.

[0082] Then, use a USB serial communication device to connect the test device to the display device, and use a USB serial communication device to connect the test device to the camera on the test bracket, and check whether the connection is normal through the test device to ensure that the data transmission between the devices is normal.

[0083] In the embodiment of the present application, the display device can support multiple signal channels. Therefore, when testing the re-display rate of the display device, the signal channel that needs to be tested by the display device can be set to perform the re-display rate test.

[0084] The signal channel refers to the transmission path for the display device to receive and process various signals (including video, audio, control signals, etc.). These signals can be transmitted to the display device via wired or wireless means.

[0085] For example, when the display device is a television, the wired method may include: a cable television network, an HDMI (High Definition Multimedia Interface) cable, etc.; the wireless method may include: a satellite signal, a terrestrial digital television signal, etc.

[0086] In some embodiments, in order to test the reproduction rate of the display device under different signal channels, before the step of "outputting a test signal to the display device so that the display device displays a test image corresponding to the test signal", the method may further include the following steps:

[0087] Send a channel switching instruction to the display device to control the display device to switch to the signal channel to be tested.

[0088] The channel switching instruction instructs the display device to switch to the signal channel to be tested. The signal channel to be tested refers to the signal channel in the display device that needs to be tested for the refresh rate.

[0089] The channel switching instruction can be triggered by the automation software in the test device and sent to the display device.

[0090] In some embodiments, before sending a channel switching instruction to the display device, signal channels that the display device needs to test may be determined as signal channels to be tested, and then the display device may be connected to all signal channels to be tested.

[0091] In the embodiment of the present application, automated software for debugging the refresh rate may be designed and installed on the test equipment.

[0092] After the signal channel to be tested of the display device is determined, the adjustment scheme can be set on the automation software according to the signal channel to be tested.

[0093] The adjustment scheme of the signal channel to be tested may include: the signal channel to be tested, and information such as the standard re-display rate and serial port command protocol corresponding to each signal channel to be tested.

[0094] Among them, since different display devices may support different serial port command protocols, the serial port protocol commands of the display device under each signal channel to be tested can be defined in the adjustment scheme to ensure that the display device normally receives the test signal through the corresponding serial port protocol commands.

[0095] For example, the signal channels supported by the display device may include: DTV (Digital Television), ATV (Analog Television), AV (Audio-Visual), HDMI, etc. Then it can be determined that the signal channels to be tested of the display device include: DTV, ATV, AV and HDMI.

[0096] In some embodiments, the step of “outputting a test signal to a display device so that the display device displays a test image corresponding to the test signal” may include the following operations:

[0097] A test signal corresponding to the signal channel to be tested is output to the display device, so that the display device displays a test image through the signal channel to be tested.

[0098] The test signal corresponding to the signal channel to be tested refers to a test signal containing information about the signal channel to be tested.

[0099] For example, the signal channel to be tested may be DTV, and the test signal corresponding to the DTV may be a DTV signal carrying a test image. When the display device receives the DTV signal, the test image may be displayed through the DTV channel.

[0100] In the embodiment of the present application, for the signal channels to be tested, a test signal corresponding to each signal channel to be tested can be generated according to the test image, so that the display device can display the test image through the corresponding signal channel to be tested after receiving the test signal. Then, the re-display rate of each signal channel to be tested is tested.

[0101] In the embodiment of the present application, the display device may support multiple display modes, and the display mode may include multiple types, for example, the display mode may include a display aspect ratio, etc. Under the same signal channel, the display device may select different display modes and may have different redisplay rates.

[0102] Therefore, when testing the re-display rate of a display device, the display mode that needs to be tested on the display device can be set to perform the re-display rate test.

[0103] For example, the display mode may be a display screen ratio, and the display screen ratio may include: AUTO (automatic), FULL (full), ZOOM (zoom), 4:3 and other ratios.

[0104] In some embodiments, in order to test the re-display rates of different display modes of a display device under different signal channels, before the step of "outputting a test signal corresponding to the signal channel to be tested to the display device so that the display device displays a test image through the signal channel to be tested", the method may further include the steps of:

[0105] Send a display mode switching instruction to the display device to control the display device to switch to the display mode to be tested.

[0106] The display mode switching instruction instructs the display device to switch to the display mode to be tested. The display mode to be tested refers to the display mode in the display device that needs to be tested for the refresh rate.

[0107] The mode switching instruction may be triggered by the automation software in the test device and sent to the display device.

[0108] In some embodiments, before sending a channel switching instruction to the display device, the display mode that the display device needs to test can be determined as the display mode to be tested. The display mode to be tested can then be added to the adjustment scheme, that is, the adjustment scheme of the signal channel to be tested can include: the signal channel to be tested, the display mode to be tested, and the standard re-display rate and serial port command protocol corresponding to each signal channel to be tested and the display mode to be tested.

[0109] For example, the display screen ratios supported by the display device may include: AUTO, FULL, ZOOM, and 4:3. Then, it can be determined that the display modes to be tested of the display device may include: AUTO, FULL, ZOOM, and 4:3 screen display ratios.

[0110] In some embodiments, the step of “outputting a test signal to a display device so that the display device displays a test image corresponding to the test signal” may include the following operations:

[0111] A test signal corresponding to the signal channel to be tested is output to the display device, so that the display device displays a test image through the signal channel to be tested according to the display mode to be tested.

[0112] Among them, since the display mode of the display device has been controlled to be switched to the display mode to be tested before the test signal is output to the display device, after the display device receives the test signal corresponding to the signal channel to be tested, it can display the test image through the signal channel to be tested and according to the display mode to be tested.

[0113] For example, the display mode to be tested may be AUTO, and the signal channel to be tested may be ATV. After the display device receives the test signal corresponding to the ATV channel, it may display the test image according to AUTO through the ATV channel.

[0114] 102. During the test image display period, obtain a target image captured by a camera from a display screen of a display device.

[0115] During the period when the display device displays the test image through the display screen, the display screen of the display device can be photographed by a camera arranged on the test bracket to obtain the target image.

[0116] The target image refers to an image obtained by photographing a display screen of the display screen through a camera when the display screen of the display device displays a test image.

[0117] In some embodiments, the display device re-display rate may include a horizontal re-display rate and a vertical re-display rate, and a plurality of cameras may be provided to respectively capture images of the display screen in different directions.

[0118] Among them, multiple cameras can be respectively arranged on each side of the display screen of the display device.

[0119] For example, see Figure 2 Each side of the test bracket 103 may correspond to each side of the display screen of the display device, and a camera 104 is disposed on each side of the test bracket 103, and images of different parts of the display screen of the display screen can be collected by each camera 104. For example, the upper part of the display screen of the display screen can be collected by the camera 104 on the top side of the test bracket 103.

[0120] In some embodiments, the step of “obtaining a target image captured by a camera on a display screen of a display device” may include the following steps:

[0121] Sending shooting instructions to each camera so that each camera shoots the display screen according to the shooting instructions, obtains the shot image and transmits it;

[0122] Receive the captured images transmitted by each camera and obtain the target image collected by each camera.

[0123] The shooting instruction instructs the camera to start shooting images.

[0124] Among them, the shooting command can be triggered by the automation software in the test equipment and sent to the camera.

[0125] Specifically, after receiving the shooting instruction, the camera can shoot the display screen of the display screen to obtain a captured image, and then transmit the captured image to the test equipment. The test equipment can use the captured image transmitted by each camera as the target image collected by each camera.

[0126] For example, see Figure 4 , Figure 4 A schematic diagram of an application scenario of a method for testing a display device provided in an embodiment of the present application. Figure 4 The display screen shown is a screen in which a test image is displayed through a display screen after the display device receives a test signal.

[0127] The display screen is photographed by each camera on the test bracket to obtain multiple target images. For example, the display screen is photographed by camera 1041 to obtain target image 10; the display screen is photographed by camera 1042 to obtain target image 20; the display screen is photographed by camera 1043 to obtain target image 30; and the display screen is photographed by camera 1044 to obtain target image 40.

[0128] 103. Perform image recognition on the target image, and determine a target reproduction rate of the test image on the display device based on the image recognition result.

[0129] In the application embodiment, an image recognition model is configured in the automation software, and the image recognition model can be used to perform recognition processing on the captured target image to obtain an image recognition result.

[0130] In some embodiments, the preset test image may be an image containing a numerical value, and the image recognition model may be used to perform numerical recognition on the target image to identify the numerical value contained in the target image.

[0131] In some embodiments, in order to improve the recognition accuracy of the image recognition model, before configuring the image recognition model to the automation software, the preset recognition model can be trained to obtain the image recognition model.

[0132] Among them, the preset recognition model can be a convolutional neural network, and the training process of the preset recognition model can include: first obtaining multiple image samples containing numerical values, training the preset recognition model through the image samples, until the numerical values ​​of the image samples recognized by the preset recognition model are the same as the numerical values ​​actually contained in the image samples, and obtaining the image recognition model.

[0133] In some embodiments, in order to reduce the workload of testers, the step of "performing image recognition on the target image, and determining the target re-display rate of the test image on the display device based on the image recognition result" may include the following operations:

[0134] Identify boundary values ​​among the numerical values ​​displayed in the target image;

[0135] Based on the boundary value and the correlation between the boundary value and the reproducibility ratio, the target reproducibility ratio of the test image on the display device is calculated.

[0136] The boundary value refers to the maximum value or the minimum value of the numerical values ​​displayed in the identified target image.

[0137] Specifically, identifying the boundary value of the displayed numerical value in the target image may include: performing recognition processing on the target image through an image recognition model to obtain at least one numerical value displayed in the target image, and then filtering out a maximum value or a minimum value from the at least one numerical value as the boundary value.

[0138] There are multiple ways to determine the boundary value from at least one value, such as filtering out the maximum value from at least one value as the boundary value, or filtering out the minimum value from at least one value as the boundary value. In the embodiment of the present application, the way to determine the boundary value can be selected according to different test images.

[0139] In some embodiments, the numerical value displayed in the test image may be a scale value.

[0140] For example, see Figure 5 , Figure 5 A schematic diagram of a test image provided in an embodiment of the present application. Figure 5 The first test image used in the solution of the present application is shown, and the numerical value displayed in the first test image may be a scale value.

[0141] When the numerical value displayed in the test image may be a scale value, the numerical value displayed in the target image may also be a scale value. In this case, the boundary value may be determined by determining the minimum numerical value as the boundary value. The boundary value may be the minimum scale value displayed in the target image. The step of "calculating the target re-display rate of the test image on the display device based on the boundary value and the correlation between the boundary value and the re-display rate" may include the following operations:

[0142] According to the correlation between the scale value and the re-display rate, the re-display rate corresponding to the minimum scale value is determined to obtain the target re-display rate.

[0143] Specifically, according to the correlation between the scale value and the re-display rate, the re-display rate corresponding to the minimum scale value is determined, and the target re-display rate can be obtained as follows:

[0144] First, it is determined whether the minimum scale value is a preset scale value, and if the minimum scale value is a preset scale value, it can be determined that the re-display rate is 100%. The preset scale value can be 0.

[0145] If the minimum scale value is not the preset scale value, the difference between 100 and the minimum scale value can be calculated. For example, the minimum scale value can be 3, and the preset scale value can be 0. It can be determined that the minimum scale value is not the preset scale value, and 100-3=97 can be calculated, and the re-display rate can be 97%.

[0146] In some embodiments, the numerical value displayed in the test image may be a re-display rate value.

[0147] For example, see Figure 6 , Figure 6 A schematic diagram of another test image provided in an embodiment of the present application. Figure 6 The second test image used in the solution of the present application is shown, and the numerical value displayed in the second test image may be a re-display rate value.

[0148] When the value displayed in the test image can be a re-display rate value, the value displayed in the target image also belongs to the re-display rate value. At this time, the boundary value can be determined by determining the maximum value as the boundary value, and the boundary value can be the maximum re-display rate value displayed in the target image. Then the step of "calculating the target re-display rate of the test image on the display device based on the boundary value and the correlation between the boundary value and the re-display rate" can include the following operations:

[0149] Based on the maximum re-display rate value, the target re-display rate is obtained.

[0150] When the value displayed in the test image is a re-display rate value, the maximum re-display rate value in the identified target image may be used as the target re-display rate obtained in the current test.

[0151] For example, when it is identified that the maximum re-display rate value displayed in the target image is 99, it can be determined that the target re-display rate obtained by the current test is 99%.

[0152] In some embodiments, the test image may also be in other styles, for example, Figure 7 , Figure 7 A schematic diagram of another test image provided in an embodiment of the present application. Figure 7 The third test image used in the present application is shown. In the third test image, the middle area can be a blank area, and color areas can be set on the four sides. The color areas have fixed widths and heights. When determining the reproduction rate according to the target image, the width and / or height of the color area contained in the target image can be compared with the width and / or height of the color area in the test image to calculate the reproduction rate.

[0153] In some embodiments, in order to ensure that the target reproduction rate of each signal channel to be tested by the display device meets the standard reproduction rate, the method may further include the following steps:

[0154] Compare the target reappearance rate with the standard reappearance rate;

[0155] If the target re-display rate does not meet the standard re-display rate, it is determined that the target re-display rate needs to be debugged;

[0156] If the target re-display rate meets the standard re-display rate, it is determined that the target re-display rate does not need to be debugged.

[0157] Among them, the standard re-display rate refers to the standard re-display rate corresponding to each signal channel to be adjusted recorded in the adjustment plan. The standard re-display rate corresponding to each signal channel to be adjusted can be set according to different re-display rate requirements. For example, for the HDMI channel, the re-display rate requirement may include: the screen display ratio mode is: under AUTO, the re-display rate requirement is 98%.

[0158] Among them, comparing the target repetition rate with the standard repetition rate may include: determining the target signal channel to be tested and the target display mode to be tested corresponding to the target repetition rate, and then determining the standard repetition rate corresponding to the target signal channel to be tested and the target display mode to be tested from the adjustment scheme, and then comparing the target repetition rate with the standard repetition rate.

[0159] The target re-display rate not meeting the standard re-display rate may include: the target re-display rate is greater than or less than the standard re-display rate. If the target re-display rate does not meet the standard re-display rate, it can be determined that the target re-display rate does not meet the requirement, that is, debugging is required.

[0160] The target re-display rate meeting the standard re-display rate may include: the target re-display rate is equal to the standard re-display rate. If the target re-display rate meets the standard re-display rate, it can be determined that the target re-display rate meets the requirement, and no debugging is required, and the target re-display rate can be saved.

[0161] In the embodiment of the present application, by intelligently identifying the target image and then determining the target re-display rate corresponding to the target image according to the identification result, errors in manually calculating the re-display rate can be avoided, thereby improving the accuracy of the re-display rate test result.

[0162] In some embodiments, in order to adjust the re-display rate to meet the requirements, the method may further include the following steps:

[0163] If the target re-display rate needs to be debugged, the current re-display rate parameter of the display device is obtained;

[0164] Determining adjustment information of a current re-display rate parameter based on a difference between the target re-display rate and the standard re-display rate;

[0165] The adjustment information is sent to the display device so that the display device adjusts the current re-display rate parameter according to the adjustment information.

[0166] In the embodiment of the present application, the re-display rate parameter may include an OverScan Adjust parameter, and the OverScan Adjust parameter generally refers to a parameter used to adjust an overscan setting in a display device (such as a television, a monitor, etc.).

[0167] Among them, the OverScan Adjust parameter can include the overscan percentage. Users can set the overscan percentage to control the degree to which the image edges are cropped. A lower percentage means less cropping, and a higher percentage means more cropping. In other words, the higher the scan percentage value, the more the image is cropped, and the lower the re-display rate; the lower the scan percentage value, the less the image is cropped, and the higher the re-display rate.

[0168] In some embodiments, the re-display rate parameter may include four parameter values: left, right, top, and bottom. The larger the value, the smaller the re-display rate. The test device may directly read the current re-display rate parameter of the display device through the serial port.

[0169] Among them, based on the difference between the target re-display rate and the standard re-display rate, determining the adjustment information of the current re-display rate parameter may include: calculating the difference between the target re-display rate and the standard re-display rate; if the target re-display rate is greater than the standard re-display rate, the re-display rate needs to be reduced, and then it can be determined that the adjustment information may include: increasing the re-display rate parameter according to the difference; if the target re-display rate is less than the standard re-display rate, the re-display rate needs to be increased, and then it can be determined that the adjustment information may include: decreasing the re-display rate parameter according to the difference.

[0170] Furthermore, after the adjustment information of the re-display rate parameter is determined, the adjustment information may be sent to the display device, so that the display device adjusts the current re-display rate parameter according to the adjustment information.

[0171] In the process of the display device adjusting the current re-display rate parameters according to the adjustment information, the display screen of the display device can be changed synchronously, so as to quickly adjust the re-display rate of the display device to a standard reference rate that meets the requirements according to the adjustment information.

[0172] In some embodiments, in order to improve the accuracy of debugging, after adjusting the re-display rate parameters according to the adjustment information, the test step can be performed again. That is, it includes: outputting a test signal to the display device so that the display device displays a test image corresponding to the test signal; during the display of the test image, obtaining a target image captured by the camera for the display screen of the display device; performing image recognition on the target image, and determining the target re-display rate of the test image on the display device based on the image recognition result. Until the target re-display rate meets the standard re-display rate, the debugging can be stopped, and the target re-display rate that meets the standard re-display rate and the corresponding channel to be tested and the display mode to be tested are saved.

[0173] In some embodiments, after the refresh rate test and debugging of a signal channel to be tested of the display device are completed, other signal channels to be tested and display modes to be tested of the display device can be switched to continue executing the test steps until all signal channels to be tested and all display modes to be tested of the display device are tested and debugged to be qualified.

[0174] The embodiment of the present application discloses a method for testing a display device, which includes: outputting a test signal to the display device so that the display device displays a test image corresponding to the test signal; during the display of the test image, obtaining a target image captured by a camera for a display screen of the display device; performing image recognition on the target image, and determining a target re-display rate of the test image on the display device based on the image recognition result. In this way, the test workload of the tester can be reduced, thereby improving the re-display rate test efficiency of the display device.
