[0024] Various modifications and changes can be made to the present application in matters of form and details without departing from the spirit and scope of the present application, which will be apparent to one skilled in the art. Thus, the present application intends to cover all modifications and changes as falling within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction.

[0025] The embodiments of the present application provide a display panel testing device, equipment and method, which will be described below in combination with the accompanying drawings.

[0026] Figure 1 A structural schematic diagram of a display panel testing device provided by the embodiments of the present application is shown in the figure. Figure 1 As described above, the testing device comprises a control module 10, a first testing module 21 and a second testing module 22.

[0027] The first testing module 21 is configured to be connected with the control module 10, and the second testing module 22 is configured to be connected with the control module 10. The control module 10 is configured to detect the testing module 20 after accessing any one of the first testing module 21 and the second testing module 22, and determine whether the accessed testing module 20 is the first testing module 21 or the second testing module 22.

[0028] In the detection stage, the control module 10 can assign different running modes to the first testing module 21 and the second testing module 22 respectively. In addition, under certain conditions, in the detection stage, the control module 10 can also assign the same running mode to the first testing module 21 and the second testing module 22.

[0029] The first testing module 21 is configured to collect optical data of the display panel at a first sampling speed according to the running mode assigned by the control module 10. The second testing module 22 is configured to collect optical data of the display panel at a second sampling speed according to the running mode assigned by the control module 10. Since there is a hardware difference between the first testing module 21 and the second testing module 22, the first sampling speed of the first testing module 21 is less than the second sampling speed of the second testing module 22.

[0030] Due to the first sampling speed and the second sampling speed being different, the first test module 21 and the second test module 22 can process the collected optical data with different delay times according to the operation mode specified by the control module 10, that is, different operation modes correspond to different delay times.

[0031] For example, since the first sampling speed adopted by the first test module 21 in the process of collecting the optical data of the display panel is less than the second sampling speed adopted by the second test module 22, if the first test module 21 and the second test module 22 both process the sampled optical data with the same delay time operation mode, it may cause the first test module 21 to need to collect the optical data of the next frame after completing the collection of the optical data of the current frame, and the processing of the collected data has not been completed, thus causing the processed optical data to be missing. Or it may cause the first test module 21 to be unable to complete the collection of the optical data of the current frame, and the above situations will affect the accuracy of the display data sampling. It may also cause the second test module 22 to need to additionally wait for a period of time to collect the optical data of the next frame after completing the collection and processing of the optical data of the current frame, thus affecting the sampling efficiency.

[0032] In the process of detecting the display panel, when the control module 10 detects that the accessed test module 20 is the first test module 21 in the case of the display panel displaying low brightness, the control module 10 specifies the first test module 21 to adopt the first running mode. When the control module 10 detects that the accessed test module 20 is the second test module 22, the control module 10 specifies the second test module 22 to adopt the second running mode. The delay time of the first running mode is greater than the delay time of the second running mode. Since the first sampling speed is less than the second sampling speed, the first test module 21 needs to adopt the first running mode with a longer delay time, so as to ensure that the first test module 21 can complete the collection of the optical data of the display panel in the process of testing the display panel, and there is enough time for processing the collected data after collection. The second test module 22 needs to adopt the second running mode with a relatively shorter delay time, so as to ensure that the second test module 22 does not need to wait for a long time after completing the collection and processing of the optical data of the display panel. Thus, in the case of mixing of multiple test modules 20 on the production line, the control module 10 detects the type of the accessed test module 20 and selects a suitable running mode for it, so as to avoid the problems of abnormal optical data sampling or too long waiting time of each test module 20 due to the same running mode of multiple test modules 20, thereby improving the sampling accuracy and shortening the overall sampling time, and further improving the testing accuracy and efficiency of the display panel.

[0033] As an example, the control module 10 can be an ARM processor with a main frequency greater than 160 MHz, for example.

[0034] As another example, the control module 10 can also be an ARM processor with a main frequency of 480 MHz, a flash memory of 2M, and a RAM of 1M. The ARM processor further includes a data tightly coupled memory (DTCM) of 128k, an instruction tightly coupled memory (ITCM) of 64k, and a backup of 64k. Therefore, the control module 10 can process the testing process of the display panel at a faster speed, thereby shortening the testing time and improving the testing efficiency.

[0035] In some embodiments, in the detection stage, the control module specifies the first test module to adopt the first delay mode and the second test module to adopt the second delay mode in the case of the display panel being in the first brightness range. The delay frame number of the first delay mode is greater than the delay frame number of the second delay mode.

[0036] For example, the first delay mode can be a 4-frame delay mode, and the second delay mode can be a 1-frame delay mode. In the detection stage, the control module determines the luminance range of the current display image of the display panel. When it is determined that the luminance range is a first luminance range, the control module detects the connected test module. When it is detected that the connected test module is a first test module, the control module specifies the first test module to collect optical data of the current display image of the display panel in the first delay mode. When it is detected that the connected test module is a second test module, the control module specifies the second test module to collect optical data of the current display image of the display panel in the second delay mode.

[0037] Since the first sampling speed of the first test module is less than the second sampling speed of the second test module, the first test module can ensure that the optical data of the display panel is collected in the process of testing the display panel in the first delay mode of 4-frame delay, and there is sufficient time for processing the collected data after the collection. The second test module can ensure that the second test module does not need to wait for a long time after completing the collection and processing of the optical data of the display panel in the second delay mode of 1-frame delay. Thus, the first test module with a slower sampling speed can complete the collection and processing of the optical data by using the first delay mode with a longer delay, thereby avoiding the problem of abnormal data processing caused by too short delay time. The second test module with a faster sampling speed can collect the optical data of the next image after completing the collection and processing of the optical data without waiting for a long time by using the second delay mode with a shorter delay, thereby shortening the data collection time. Therefore, the present application can use the most suitable delay mode for each test module in the case of multiple test modules in the production line, thereby improving the overall test accuracy and efficiency of the production line.

[0038] It should be noted that the first delay mode with a 4-frame delay and the second delay mode with a 1-frame delay are only examples, and the specific delay frame number needs to be set according to the actual sampling speed of the test module, which is not limited here.

[0039] As an example, the first luminance range includes at least 1 nit to 10 nit. The first luminance range is a low-brightness display condition of the display panel.

[0040] In some embodiments, in the detection stage, when the display panel is in a second luminance range, the control module uses a third delay mode for the first test module and the second test module.

[0041] For example, the delay frame number of the third delay mode can be, for example, 1 frame. In the detection stage, the control module determines the brightness range of the current display panel, and when it is determined that the brightness range is the second brightness range, the control module specifies the first test module to collect the optical data of the current display panel in the third delay mode when the test module connected to the control module is the first test module, or the control module specifies the second test module to collect the optical data of the current display panel in the third delay mode when the test module connected to the control module is the second test module. In the second brightness range, the optical data of the display panel is easier to collect.

[0042] Since the optical data of the display panel in the second brightness range is easier to collect, even if the sampling speed of the first test module is slow, the optical data of the display panel can still be collected quickly. Therefore, the first test module and the second test module work in the second brightness range and collect the optical data of the display panel in the third delay mode, thereby shortening the time for collecting the optical data of the display panel. Thus, in the second brightness range where the optical data of the display panel is easier to collect, the first test module and the second test module both use the third delay mode. After quickly collecting and processing the optical data, the next frame of optical data can be collected without waiting for a long time, thereby shortening the data collection time and improving the overall efficiency of the production line.

[0043] It should be noted that the delay frame number of the third delay mode is 1 frame, which is only an example. The specific delay frame number needs to be set according to the actual sampling speed of the test module, which is not limited here.

[0044] As an example, the second brightness range includes at least 11 nit to 3000 nit. The second brightness range is a high-brightness display condition of the display panel.

[0045] In some embodiments, in the detection stage, the control module is configured to determine the frame duration of each frame in the running mode according to the refresh rate of the display panel. In any two running modes with different refresh rates, the frame duration of each frame is different.

[0046] For example, the frame duration of each frame can be calculated according to the following formula:

[0047]

[0048] Wherein, T is the frame duration, and f is the refresh rate of the display panel.

[0049] For example, when the refresh rate of the display panel is 90Hz, the frame duration of each frame is 22.22ms. This application sets the frame duration of each frame of the first test module and the second test module in the operating mode according to the refresh rate of the display panel, so that different refresh rates correspond to different frame durations, rather than using the same frame duration under all refresh rate conditions. In this way, when the display panel is at a high refresh rate, a shorter frame duration can be used, thereby shortening the data collection time under high refresh rate conditions, thereby improving the overall efficiency of the production line.

[0050] In some embodiments, Figure 2 A schematic structural diagram of another display panel testing device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the control module 10 also includes a first communication interface 11 and a second communication interface 12; the first communication interface 11 is used to connect to the first test module 21, and the second communication interface 12 is used to connect to the second test module 22. At least one of the first communication interface 11 and the second communication interface 12 uses a communication interface with a faster information transmission speed, such as a USB interface. The other may also use a communication interface with a faster information transmission speed, such as an RS-232 communication interface or a CA410 communication interface. By increasing the information transmission speed between the first test module 21 and the second test module 22 and the control module 10, the time for the first test module 21 and the second test module 22 to collect optical data of the display panel is shortened, thereby improving the overall efficiency of the production line.

[0051] It should be noted that the first communication interface 11 and the second communication interface 12 being USB interfaces is merely an example. The first communication interface 11 and the second communication interface 12 may also be other interfaces with faster information transmission speeds, which is not specifically limited here.

[0052] As an example, at least one of the first communication interface and the second communication interface is a USB interface. One of the first communication interface and the second communication interface can be a USB interface, and the other can be another interface with a faster information transmission speed. Alternatively, both the first communication interface and the second communication interface can be USB interfaces.

[0053] The present application also provides a display panel testing device, comprising any one of the testing devices described in the above embodiments.

[0054] It can be understood that the testing equipment provided in the embodiment of the present application can achieve the corresponding beneficial effects of the testing device provided in the above-mentioned embodiment, which will not be described in detail here.

[0055] An embodiment of the present application further provides a method for testing a display panel, which is applied to any one of the testing devices described in the above embodiments. Figure 3A flowchart of a test method of a display panel provided by an embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the test method comprises the following steps. Figure 3

[0056] In S310, a display parameter of the display panel and a target test module corresponding to the display panel are acquired.

[0057] For example, the control module acquires the display parameter of the display panel and acquires the target test module connected to the control module. The target test module is one of the first test module and the second test module. The display parameter can be, for example, a parameter such as brightness and refresh rate of the display panel.

[0058] In S320, a running mode corresponding to the target test module is specified based on the target test module and the display parameter.

[0059] For example, the control module specifies the running mode corresponding to the target test module according to the acquired target test module and the display parameter of the display panel. For example, in the case where the control module acquires that the display panel displays low brightness and the first test module is connected, the control module specifies that the first test module adopts the first running mode. In the case where the control module acquires that the display panel displays low brightness and the second test module is connected, the control module specifies that the second test module adopts the second running mode. The delay time of the first running mode is greater than the delay time of the second running mode. Since the first sampling speed of the first test module is less than the second sampling speed of the second test module, the first test module needs to adopt the first running mode with a longer delay time, so as to ensure that the first test module can complete the collection of optical data of the display panel in the process of testing the display panel, and has sufficient time for processing the collected data after the collection. The second test module needs to adopt the second running mode with a relatively shorter delay time, so as to ensure that the second test module does not need to wait for a long time after completing the collection and processing of the optical data of the display panel. Thus, in the case where multiple test modules are mixed on the production line, the control module detects the type of the connected test module, and selects a suitable running mode for the test module according to the display condition of the display panel, so as to avoid the problem that multiple test modules adopt the same running mode, and the optical data sampling of each test module is abnormal or the waiting time is too long, thereby improving the sampling accuracy, shortening the overall sampling time, and further improving the test precision and efficiency of the display panel.

[0060] In some embodiments, the display parameter comprises a brightness parameter. Figure 4 A flowchart of another test method of a display panel provided by an embodiment of the present application is shown in FIG. 2. As shown in FIG. 2, the test method comprises the following steps. Figure 4 ​As shown, based on the target test module and the display parameter, a running mode corresponding to the target test module is specified, including:

[0061] S321, in a case where the brightness parameter meets the first brightness range and the target test module is the first test module, the target test module is specified to run in a first delay mode.

[0062] For example, the delay frame number of the first delay mode can be, for example, delay 4 frames. In a case where the brightness parameter of the display panel meets the first brightness range and the test module connected with the control module is the first test module, the control module specifies the first test module to run in the first delay mode. The present application adopts the first delay mode with longer delay for the first test module with slower sampling speed, so that the first test module can complete the collection and processing of optical data, avoiding the problem of abnormal data processing due to too short delay time.

[0063] S322, in a case where the brightness parameter meets the first brightness range and the target test module is the second test module, the target test module is specified to run in a second delay mode.

[0064] For example, the delay frame number of the second delay mode can be, for example, delay 1 frame. In a case where the brightness parameter of the display panel meets the first brightness range and the test module connected with the control module is the second test module, the control module specifies the second test module to run in the second delay mode. The present application adopts the second delay mode with shorter delay for the second test module with faster sampling speed, so that the second test module can collect optical data of the next picture after completing the collection and processing of optical data, without waiting for a long time, thereby shortening the data collection time.

[0065] The present application adopts the first delay mode for the first test module with slower sampling speed and the second delay mode for the second test module with faster sampling speed, wherein the delay frame number of the first delay mode is greater than that of the second delay mode. When there are multiple test modules on the production line, the most suitable delay mode is adopted for each test module, so as to ensure the collection accuracy of optical data and reduce the data collection time, thereby improving the overall test accuracy and efficiency of the production line.

[0066] It should be noted that the delay frame number of the first delay mode is delay 4 frames and the delay frame number of the second delay mode is delay 1 frame, which are only examples, and the specific delay frame number needs to be set according to the actual sampling speed of the test module, which is not limited here.

[0067] In some embodiments, Figure 5 Another flowchart of a test method of a display panel provided by the present application is shown in FIG. 6.Figure 5 As shown, based on the target test module and the display parameter, the running mode corresponding to the target test module is specified, and the method further includes:

[0068] S323, in a case where the brightness parameter meets the second brightness range, the target test module is specified to run in a third delay mode.

[0069] For example, the delay frame number of the third delay mode can be, for example, 1 frame. When the brightness parameter of the display panel meets the second brightness range, the control module directly specifies the first test module or the second test module to run in the second delay mode. In a case where the brightness parameter of the display panel is in the second brightness range and the test module accessing the control module is the first test module, the control module specifies the first test module to collect the optical data of the current display panel in the third delay mode. Or in a case where the test module accessing the control module is the second test module, the control module specifies the second test module to collect the optical data of the current display panel in the third delay mode. In the second brightness range, the optical data of the display panel is easier to collect.

[0070] Since the optical data of the display panel in the second brightness range is easier to collect, even if the sampling speed of the first test module is slow, the optical data of the display panel can still be collected quickly. Therefore, the first test module and the second test module work in the third delay mode to collect the optical data of the display panel in the second brightness range, so as to shorten the time for collecting the optical data of the display panel. Thus, in a case where the display panel is in the second brightness range in which the optical data is easier to collect, the first test module and the second test module are both in the third delay mode. After the optical data is collected and processed quickly, the optical data of the next frame can be collected without waiting for a long time, thereby shortening the data collection time and improving the overall efficiency of the production line.

[0071] It should be noted that the delay frame number of the third delay mode is 1 frame, which is only an example. The specific delay frame number needs to be set according to the actual sampling speed of the test module, which is not limited here.

[0072] In some embodiments, the display parameter includes a refresh rate. Figure 6 Another flowchart of a test method of a display panel provided by an embodiment of the present application is shown in FIG. 6. Figure 6 As shown, based on the target test module and the display parameter, the running mode corresponding to the target test module is specified, and the method further includes:

[0073] S324, based on the refresh rate, the frame time of each frame in the running mode corresponding to the target test module is determined.

[0074] The control module calculates the frame duration of each frame according to the obtained refresh rate of the display panel by a calculation formula: The frame duration of each frame is calculated, where T is the frame duration and f is the refresh rate of the display panel. For example, when the refresh rate of the display panel is 90Hz, the frame duration of each frame is 22.22ms.

[0075] The present application sets the first test module and the second test module according to the refresh rate of the display panel to have different frame durations in the running mode, instead of using the same frame duration in all refresh rate cases. In this way, a shorter frame duration can be used when the display panel is in a high refresh rate state, thereby shortening the data collection time in the high refresh rate state and improving the overall efficiency of the production line.
