[0024] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

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

[0026] Figure 1 A schematic diagram of a display panel testing device provided in an embodiment of the present application is shown in FIG. Figure 1 The testing device includes: a control module 10 , a first testing module 21 and a second testing module 22 .

[0027] The first test module 21 is used to connect to the control module 10, and the second test module 22 is used to connect to the control module 10. The control module 10 is used to detect the test module 20 after accessing any one of the first test module 21 and the second test module 22, and determine whether the accessed test module 20 is the first test module 21 or the second test module 22.

[0028] During the detection phase, the control module 10 may specify different operation modes for the first test module 21 and the second test module 22. In addition, under certain conditions, during the detection phase, the control module 10 may also specify the same operation mode for the first test module 21 and the second test module 22.

[0029] The first test module 21 is used to collect optical data of the display panel at a first sampling speed according to the operation mode specified by the control module 10. The second test module 22 is used to collect optical data of the display panel at a second sampling speed according to the operation mode specified by the control module 10. In particular, due to the hardware difference between the first test module 21 and the second test module 22, the first sampling speed of the first test module 21 is less than the second sampling speed of the second test module 22.

[0030] Since the first sampling speed is different from the second sampling speed, the first test module 21 and the second test module 22 can process the collected optical data using 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 test module 21 uses a first sampling speed that is lower than the second sampling speed used by the second test module 22 during the process of collecting optical data of the display panel, if the first test module 21 and the second test module 22 both use the same delay time operation mode to process the sampled optical data, it may cause the first test module 21 to collect the optical data of the next picture after completing the collection of the optical data of the current picture, but before completing the processing of the collected data, thus causing the optical data after processing 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 picture, all of which will affect the accuracy of the display data sampling. It may also cause the second test module 22 to wait for an additional period of time before collecting the optical data of the next picture after completing the sampling and processing of the optical data of the current picture, thereby affecting the sampling efficiency.

[0032] In the process of testing the display panel, when the display panel displays low brightness, when the control module 10 detects that the connected test module 20 is the first test module 21, the control module 10 specifies the first test module 21 to adopt the first operating mode. When the control module 10 detects that the connected test module 20 is the second test module 22, the control module 10 specifies the second test module 22 to adopt the second operating mode. Among them, the delay time of the first operating mode is greater than the delay time of the second operating mode. Since the first sampling speed is less than the second sampling speed, the first test module 21 needs to adopt the first operating mode with a longer delay time, so as to ensure that the first test module 21 can complete the collection of optical data of the display panel during the test of the display panel, and there is enough time for processing the collected data after the collection. The second test module 22 needs to adopt the second operating mode with a relatively shorter delay time, so as to ensure that the second test module 22 does not need to wait too long after completing the collection and processing of the optical data of the display panel. Therefore, when there are multiple test modules 20 mixed in the production line, the present application detects the type of the connected test module 20 through the control module 10 and selects a suitable operating mode for it, thereby avoiding the problem of abnormal optical data sampling or long waiting time in each test module 20 due to the use of the same operating mode by multiple test modules 20, thereby improving the accuracy of sampling, 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 may be an ARM processor with a main frequency greater than 160 MHz.

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

[0035] In some embodiments, during the detection phase, when the display panel is in a first brightness range, the control module specifies a first delay mode for the first test module and a second delay mode for the second test module; wherein the number of delay frames of the first delay mode is greater than the number of delay frames of the second delay mode.

[0036] Exemplarily, the number of delayed frames of the first delay mode may be, for example, 4 frames, and the number of delayed frames of the second delay mode may be, for example, 1 frame. In the detection stage, the control module determines the brightness range of the current display screen of the display panel. When it is determined that the brightness range is the first brightness range, the control module detects the connected test module. When it is detected that the first test module is connected, the control module specifies the first test module to use the first delay mode to collect optical data of the current display screen of the display panel. When the control module detects that the second test module is connected, the control module specifies the second test module to use the second delay mode to collect optical data of the current display screen of the display panel.

[0037] Since the first sampling speed of the first test module is less than the second sampling speed of the second test module, when the first test module adopts the first delay mode with a delay of 4 frames, it can ensure that the optical data of the display panel can be collected during the test of the display panel, and there is enough time for processing the collected data after the collection. When the second test module adopts the second delay mode with a delay of 1 frame, it can ensure that the second test module does not need to wait too long after completing the collection and processing of the optical data of the display panel. Therefore, the present application adopts the first delay mode with a longer delay for the first test module with a slower sampling speed, so that the first test module can complete the collection and processing of the optical data, thereby avoiding the problem of abnormal data processing caused by too short a delay time. And by adopting the second delay mode with a shorter delay for the second test module with a faster sampling speed, the second test module can collect the optical data of the next picture without waiting for a long time after completing the collection and processing of the optical data, thereby shortening the data collection time. Therefore, the present application can adopt the most suitable delay module for each test module when there are 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 delay frame number of the first delay mode is 4 frames, and the delay frame number of the second delay mode is 1 frame. These are only examples. The specific delay frame number needs to be set according to the actual sampling speed of the test module and is not specifically limited here.

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

[0040] In some embodiments, during the detection phase, when the display panel is in the second brightness range, the control module adopts the third delay mode for both the first test module and the second test module.

[0041] Exemplarily, the number of delayed frames of the third delay mode may be, for example, a delay of 1 frame. In the detection stage, the control module determines the brightness range of the current display screen of the display panel. When it is determined that the brightness range is the second brightness range, if the test module connected to the control module is the first test module, the control module specifies the first test module to use the third delay mode to collect optical data of the current display screen of the display panel. Or if the test module connected to the control module is the second test module, the control module specifies the second test module to use the third delay mode to collect optical data of the current display screen of the display panel. Among them, 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 is easier to collect when it is in the second brightness range, even if the sampling speed of the first test module is slower, the collection of the optical data of the display panel can still be completed quickly. Therefore, the first test module and the second test module both adopt the third delay mode to collect the optical data of the display panel when they are working in the second brightness range, thereby shortening the time for collecting the optical data of the display panel. Therefore, in the present application, when the display panel is in the second brightness range where the optical data is easier to collect, the first test module and the second test module both adopt the third delay mode. After quickly completing the collection and processing of the optical data, the optical data of the next picture 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 of 1 frame is only an example, and the specific delay frame number needs to be set according to the actual sampling speed of the test module, and is not specifically 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, during the detection phase, the control module is used to determine the frame duration of each frame in the operating mode according to the refresh rate of the display panel; wherein, in any two operating modes with different refresh rates, the frame duration of each frame is different.

[0046] Exemplarily, 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. The present 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 time for data collection under high refresh rate conditions, thereby improving the overall efficiency of the production line.

[0050] In some embodiments, Figure 2 A schematic diagram of the structure 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 are USB interfaces for example only. The first communication interface 11 and the second communication interface 12 may also be other interfaces with faster information transmission speed, 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 may be a USB interface, and the other may be an interface with a faster information transmission speed. Or both the first communication interface and the second communication interface are 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 implementation mode, which will not be elaborated here.

[0055] The embodiment of the present application further provides a display panel testing method, which is applied to any one of the testing devices described in the above embodiments. Figure 3A flow chart of a display panel testing method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the test methods include:

[0056] S310 , obtaining display parameters of a display panel and a target test module corresponding to the display panel.

[0057] Exemplarily, the control module acquires display parameters of the display panel and acquires a 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 parameters may be, for example, parameters such as brightness and refresh rate of the display panel.

[0058] S320. Based on the target test module and the display parameters, specify an operation mode corresponding to the target test module.

[0059] Exemplarily, the control module specifies the operation mode corresponding to the target test module according to the acquired target test module and the display parameters of the display panel. For example, when the control module obtains that the display panel displays low brightness and is connected to the first test module, the control module specifies that the first test module adopts the first operation mode. When the control module obtains that the display panel displays low brightness and is connected to the second test module, the control module specifies that the second test module adopts the second operation mode. Among them, the delay time of the first operation mode is greater than the delay time of the second operation 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 operation 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 during the test of the display panel, and there is enough time for processing the collected data after the collection. The second test module needs to adopt the second operation mode with a relatively shorter delay time, so as to ensure that the second test module does not need to wait too long after completing the collection and processing of the optical data of the display panel. Therefore, when there are multiple test modules mixed in the production line, the present application detects the type of connected test modules through the control module, and selects a suitable operating mode for the test module according to the display situation of the display panel, thereby avoiding the problem of abnormal optical data sampling or long waiting time in each test module due to the use of the same operating mode by multiple test modules, thereby improving the accuracy of sampling, shortening the overall sampling time, and further improving the testing accuracy and efficiency of the display panel.

[0060] In some embodiments, the display parameter includes a brightness parameter. Figure 4 A flow chart of another display panel testing method provided in an embodiment of the present application is shown as follows: Figure 4As shown, based on the target test module and display parameters, the operation mode corresponding to the target test module is specified, including:

[0061] S321. When the brightness parameter satisfies the first brightness range and the target test module is the first test module, specify the target test module to run in the first delay mode.

[0062] Exemplarily, the number of delayed frames of the first delay mode may be, for example, a delay of 4 frames. When the control module obtains that the brightness parameter of the display panel satisfies the first brightness range and the test module connected to the control module is the first test module, the control module specifies that the first test module adopts the first delay mode to operate. The present application adopts the first delay mode with a longer delay for the first test module with a slower sampling speed, so that the first test module can complete the acquisition and processing of optical data, thereby avoiding the problem of abnormal data processing caused by too short a delay time.

[0063] S322: When the brightness parameter satisfies the first brightness range and the target test module is the second test module, specify the target test module to run in the second delay mode.

[0064] Exemplarily, the delay frame number of the second delay module can be, for example, a delay of 1 frame. When the control module obtains that the brightness parameter of the display panel satisfies the first brightness range and the test module connected to the control module is the second test module, the control module specifies that the second test module adopts the second delay mode to operate. The present application adopts a second delay mode with a shorter delay for the second test module with a faster sampling speed, so that after the second test module completes the collection and processing of the optical data, it can collect the optical data of the next picture without waiting for a long time, thereby shortening the data collection time.

[0065] This application adopts a first delay mode for a first test module with a slower sampling speed, and a second delay mode for a second test module with a faster sampling speed, wherein the delay frame number of the first delay mode is greater than the delay frame number of the second delay mode. When there are multiple test modules in the production line, the most suitable delay module is adopted for each test module, thereby ensuring the acquisition accuracy of optical data and reducing the time of data acquisition, 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 4 frames, and the delay frame number of the second delay mode is 1 frame. These are only examples. The specific delay frame number needs to be set according to the actual sampling speed of the test module and is not specifically limited here.

[0067] In some embodiments, Figure 5 A flow chart of another display panel testing method provided in an embodiment of the present application is shown as follows: Figure 5 As shown, based on the target test module and the display parameters, the operation mode corresponding to the target test module is specified, and also includes:

[0068] S323. When the brightness parameter satisfies the second brightness range, specify the target test module to run in the third delay mode.

[0069] Exemplarily, the number of delayed frames of the third delay mode may be, for example, a delay of 1 frame. When the control module obtains that the brightness parameter of the display panel satisfies the second brightness range, the control module directly specifies the first test module or the second test module to operate in the second delay mode. When the control module determines that the brightness parameter of the display panel is in the second brightness range, and the test module connected to the control module is the first test module, the control module specifies the first test module to use the third delay mode to collect the optical data of the current display screen of the display panel. Or when the test module connected to the control module is the second test module, the control module specifies the second test module to use the third delay mode to collect the optical data of the current display screen of the display panel. Among them, 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 is easier to collect when it is in the second brightness range, even if the sampling speed of the first test module is slower, the collection of the optical data of the display panel can still be completed quickly. Therefore, the first test module and the second test module both adopt the third delay mode to collect the optical data of the display panel when they are working in the second brightness range, thereby shortening the time for collecting the optical data of the display panel. Therefore, in the present application, when the display panel is in the second brightness range where the optical data is easier to collect, the first test module and the second test module both adopt the third delay mode. After quickly completing the collection and processing of the optical data, the optical data of the next picture 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 of 1 frame is only an example, and the specific delay frame number needs to be set according to the actual sampling speed of the test module, and is not specifically limited here.

[0072] In some embodiments, the display parameters include a refresh rate. Figure 6 A flow chart of another display panel testing method provided in an embodiment of the present application is shown as follows: Figure 6 As shown, based on the target test module and the display parameters, the operation mode corresponding to the target test module is specified, and also includes:

[0073] S324. Determine the frame duration of each frame in the operation mode corresponding to the target test module based on the refresh rate.

[0074] The control module calculates the refresh rate of the display panel using the following 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 90 Hz, the frame duration of each frame is 22.22 ms.

[0075] The present 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.
