All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0027] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0028] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] It should be understood that although terms such as "first," "second," etc., may be used to describe voltage control signals, fixed-potential signal lines, input terminals, etc., in the embodiments of this application, these voltage control signals, fixed-potential signal lines, input terminals, etc., should not be limited to these terms. These terms are only used to distinguish voltage control signals, fixed-potential signal lines, input terminals, etc., from each other. For example, without departing from the scope of the embodiments of this application, a first voltage control signal may also be referred to as a second voltage control signal, and similarly, a second voltage control signal may also be referred to as a first voltage control signal.

[0031] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0032] Figure 1 This is a schematic diagram of a test adapter board provided in an embodiment of this application.

[0033] This application provides a test adapter board 01, which can be applied to a screen dot-matrix testing system for display modules. For example... Figure 1 As shown, the test adapter board 01 includes a conversion module 10 and a power management module 20. The input terminal of the conversion module 10 is used to connect to the external control module 02, and the output terminal is electrically connected to the power management module 20. The conversion module 10 is used to convert the first voltage control signal VP1 received from the external control module 02 into the corresponding second voltage control signal VP2, and transmit the second voltage control signal VP2 to the power management module 20.

[0034] Optionally, the first voltage control signal VP1 and the second voltage control signal VP2 are pulse signals with different parameters. Here, the parameters can refer to the frequency and pulse width of the pulse signal.

[0035] The output terminal OUT of the power management module 20 is used to externally receive the test terminal 03. The power management module 20 is used to output the test voltage Vt according to the second voltage control signal VP2 it receives, and transmit it to the test terminal 03.

[0036] In other words, the conversion module 10 can convert the first voltage control signal VP1 output by the control module 02 into a second voltage control signal VP2 that matches the power management module 20. The power management module 20 outputs the test voltage Vt required by the terminal under test 03 according to the second voltage control signal VP2.

[0037] When the test adapter board 01 is applied to the screen test system of the display module, the control module 02 connected to the conversion module 10 can be the driver chip in the display module under test, and the terminal 03 connected to the power management module 20 can be the display panel in the display module under test.

[0038] The driver chip can output a first voltage control signal VP1 based on the screen information and brightness information of the display panel. The conversion module 10 converts the first voltage control signal VP1 output by the driver chip into a second voltage control signal VP2 that matches the power management module 20. The power management module 20 outputs the test voltage Vt required by the display panel according to the second voltage control signal VP2. The display panel responds to the test voltage Vt to display.

[0039] Optionally, the test voltage Vt output by the power management module 20 is the PVDD, PVEE, AVDD, or other voltages required by the display panel.

[0040] In this embodiment, the adapter board 01 includes a conversion module 10 and a power management module 20. The conversion module 10 converts the first voltage control signal VP1 output by the external control module 02 into a second voltage control signal VP2 that matches the power management module 20, thereby controlling the power management module 20 to output a test voltage that meets the requirements. This solves the problem of driver incompatibility between control modules 02 and power management modules 20 produced by different manufacturers, improves the accuracy of the control module 02 in controlling the power management module 20 to output the test voltage, and thus helps to improve the accuracy of the test results.

[0041] Moreover, the adapter board 01 provided in this application embodiment can be reused and applied to different test projects, which is conducive to promoting the standardization of the test process, improving test efficiency, and reducing costs.

[0042] Figure 2 This is a schematic diagram of another test adapter board provided in an embodiment of this application.

[0043] In one embodiment of this application, such as Figure 2 As shown, the conversion module 10 includes a control unit 11 and an output unit 12. The input terminal of the control unit 11 is electrically connected to the input terminal of the conversion module 10. That is, the input terminal of the control unit 11 is used to connect to the external control module 02 and can receive the first voltage control signal VP1 output by the external control module 02.

[0044] The output terminal of the control unit 11 is electrically connected to the output unit 12. The control unit 11 is used to output the parameters of the second voltage control signal VP2 corresponding to the first voltage control signal VP1 and transmit them to the output unit 12. The parameters of the second voltage control signal VP2 may be information such as the frequency and pulse width of the second voltage control signal VP2.

[0045] Specifically, the control unit 11 can parse the received first voltage control signal VP1, obtain the parameters that the corresponding second voltage control signal VP2 should have based on the parsed data information and match the power management module 20, and then transmit the parameters that the corresponding second voltage control signal VP2 should have to the output unit 12.

[0046] The output terminal of the output unit 12 is electrically connected to the power management module 20. The output unit 12 is used to output the corresponding second voltage control signal VP2 according to the parameters of the second voltage control signal VP2. That is, the output unit 12 outputs a specific second voltage control signal VP2 according to the parameters of the second voltage control signal VP2 it receives. Of course, the specific second voltage control signal VP2 output by the output unit 12 meets the parameter requirements of the second voltage control signal VP2 transmitted to it by the control unit 11.

[0047] In this embodiment, the conversion module 10 includes a control unit 11 and an output unit 12 electrically connected. The control unit 11 can first obtain the parameters that the corresponding second voltage control signal VP2 should have based on the first voltage control signal VP1 it receives, and transmit them to the output unit 12. Then, the output unit 12 responds to the parameters of the second voltage control signal VP2 and outputs a specific second voltage control signal VP2 that meets the requirements. In this way, the conversion module 10 can convert the first voltage control signal VP1 it receives into a second voltage control signal VP2 that matches the power management module 20.

[0048] Figure 3 This is a schematic diagram of another test adapter board provided in an embodiment of this application.

[0049] In one implementation of the embodiments of this application, such as Figure 3 As shown, the control unit 11 in the conversion module 10 includes a detection unit 111 and a selection unit 112. The input terminal of the detection unit 111 is electrically connected to the input terminal of the conversion module 10. That is, the input terminal of the detection unit 111 is used to connect to the external control module 02 and can receive the first voltage control signal VP1 output by the external control module 02.

[0050] The output terminal of the detection unit 111 is electrically connected to the selection unit 112. The detection unit 111 is used to acquire the parameters of the first voltage control signal VP1 it receives and transmit them to the selection unit 112. The parameters of the first voltage control signal VP1 may be information such as the frequency and pulse width of the first voltage control signal VP1.

[0051] Specifically, the detection unit 111 can parse the received first voltage control signal VP1, obtain the parameters of the first voltage control signal VP1, and transmit the parameters of the first voltage control signal VP1 to the selection unit 112.

[0052] The output terminal of the selection unit 112 is electrically connected to the output unit 12. The selection unit 112 is used to obtain the parameters of the corresponding second voltage control signal VP2 according to the parameters of the first voltage control signal VP1, and transmit the parameters of the second voltage control signal VP2 to the output unit 12, thereby completing the conversion of the parameter relationship between the first voltage control signal VP1 and the second voltage control signal VP2.

[0053] In this implementation, the control unit 11 includes a detection unit 111 and a selection unit 112, meaning the conversion module 10 includes an electrically connected detection unit 111, selection unit 112, and output unit 12. The detection unit 111 first parses the parameters of the received first voltage control signal VP1 and transmits them to the selection unit 112. Then, the selection unit 112 obtains the parameters of the corresponding second voltage control signal VP2 based on the parameters of the first voltage control signal VP1 and transmits them to the output unit 12. The output unit 12, in response to the parameters of the second voltage control signal VP2, outputs a specific second voltage control signal VP2 that meets the requirements. Thus, the conversion module 10 can convert the received first voltage control signal VP1 into a second voltage control signal VP2 that matches the power management module 20.

[0054] Figure 4 This is a schematic diagram of another test adapter board provided in an embodiment of this application.

[0055] like Figure 4 As shown, in one embodiment of this application, the control unit 11 further includes a storage unit 113, which is electrically connected to the selection unit 112. The storage unit 113 is used to store a correspondence table between the parameters of the first voltage control signal VP1 and the parameters of the second voltage control signal line VP2.

[0056] Specifically, the selection unit 112 can select the parameters of the corresponding second voltage control signal line VP2 from the correspondence table of the storage unit 113 according to the parameters of the first voltage control signal VP1 it receives, and transmit them to the output unit 12.

[0057] As the above analysis shows, the voltage requirement of the terminal under test 03 is provided to the control module 02. The control module 02 outputs a first voltage control signal VP1 based on the voltage requirement of the terminal under test 03. For the power management module 20 to output the required voltage from the terminal under test 03, it needs to be controlled by a second voltage control signal VP2. Therefore, to ensure that the power management module 20 can output the test voltage Vt according to the voltage requirement of the terminal under test 03, the second voltage control signal VP2 needs to correspond to the first voltage control signal VP1.

[0058] In this embodiment, the storage unit 113 stores a correspondence table of the parameters of the first voltage control signal VP1 and the parameters of the second voltage control signal VP2. The selection unit 112 can select the parameters of the second voltage control signal VP2 that correspond to the parameters of the first voltage control signal VP1 according to the correspondence table. This helps to ensure the accuracy of the power management module 20 in receiving the second voltage control signal VP2, thereby helping to ensure the accuracy of the test voltage Vt output by the power management module 20.

[0059] It should be noted that the control module 02 can output different first voltage control signals VP1 according to the different voltage requirements of the terminal under test 03, and the selection unit 112 can select different parameters of the second voltage control signal VP2 according to the different first voltage control signals VP1.

[0060] Figure 5 for Figure 1 A schematic diagram of a power management module.

[0061] In one embodiment of this application, such as Figure 5 As shown, the power management module 20 also includes a first input terminal 21, a second input terminal 22, and a control terminal 23.

[0062] The control terminal 23 is electrically connected to the output terminal of the conversion module 10 and is used to receive the second voltage control signal VP2 output by the conversion module 10. The power management module 20 outputs the test voltage Vt in response to the second voltage control signal VP2.

[0063] The first input terminal 21 is electrically connected to the first fixed-potential signal line DL1, and the second input terminal 22 is electrically connected to the second fixed-potential signal line DL2. The voltage transmitted through the first fixed-potential signal line DL1 is greater than the voltage transmitted through the second fixed-potential signal line DL2. The voltage transmitted from the first fixed-potential signal line DL1 to the first input terminal 21 determines the maximum output voltage value of the power management module 20, and the voltage transmitted from the second fixed-potential signal line DL2 to the second input terminal 22 determines the minimum output voltage value of the power management module 20.

[0064] For example, such as Figure 5 As shown, the first fixed-potential signal line DL1 transmits voltage VH, and the second fixed-potential signal line DL2 transmits voltage VL, where VH > VL. The power management module 20 can output a minimum test voltage Vt of VL and a maximum test voltage Vt of VH.

[0065] In this embodiment, the voltage values ​​received by the first input terminal 21 and the second input terminal 22 of the power management module 20 can control the range of the test voltage Vt output by the power management module 20. The power management module 20 outputs a specific test voltage Vt according to the second voltage control signal VP2 received by its control terminal 23. This embodiment allows for flexible setting of the range of the test voltage Vt that the power management module 20 can output according to different test requirements, thereby increasing the application range of the power management module 20 and, consequently, increasing the application range of the adapter board 01.

[0066] Optionally, the test voltage output by the power management module 20 is Vt, where -15V ≤ Vt ≤ 15V. This allows the power management module 20 to output a wider range of test voltages Vt, meeting the needs of more testing scenarios.

[0067] In one implementation of the embodiments of this application, please continue to refer to Figure 5 The power management module 20 includes n resistors M between its first input terminal 21 and second input terminal 22, where n ≥ 2. The resistance value between the first input terminal 21 and the second input terminal 22 can be the sum of the resistance values ​​of the n resistors M. The n resistors include a first resistor M1 and a last resistor Mn. The first resistor M1 is electrically connected to the first input terminal 21, and the last resistor Mn is electrically connected to the second input terminal 22.

[0068] Optionally, such as Figure 5 As shown, n resistors M are connected in series, that is, the n resistors M from the first resistor M1 to the last resistor Mn are connected end to end in sequence.

[0069] It should be noted that in some other embodiments, the n resistors M can also be connected in parallel, or some of the resistors M can be connected in parallel.

[0070] In this embodiment, the power management module 20 is configured to include n resistors M between the first input terminal 21 and the second input terminal 22. The output voltage value can be adjusted by changing the number of resistors M connected between the output terminal OUT and the second input terminal 22 of the power management module 20.

[0071] Specifically, the power management module 20 flexibly adjusts the number of resistors M connected between its output terminal OUT and the second input terminal 22 according to the received second voltage control signal VP2, thereby changing the resistance value between the output terminal OUT and the second input terminal 22 of the power management module 20, and thus changing the output voltage value of the power management module 20.

[0072] Furthermore, the first fixed potential signal line DL1 transmits voltage VH, the second fixed potential signal line DL2 transmits voltage VL, VH > VL, and the test voltage output by the power management module 20 is Vt;

[0073] Vt=VL+(VH-VL)*Ro / Rn (Formula 1)

[0074] Where Rn is the sum of the resistance values ​​of n resistors M between the first input terminal 21 and the second input terminal 22 of the power management module 20, and Ro is the sum of the resistance values ​​of the resistors M between the output terminal OUT and the second input terminal 22 of the power management module 20. As can be seen from Formula 1, the value of the test voltage Vt can be changed by changing the value of Ro.

[0075] It is understandable that the number and accuracy of the resistors M set between the first input terminal 21 and the second input terminal 22 of the power management module 20 can affect the accuracy of the output voltage value of the power management module 20.

[0076] In this embodiment, the number and accuracy of resistors M can be set according to the test requirements of different projects and the range of output voltage of the power management module 20, so as to ensure that the adapter board 01 has a wide range of applications.

[0077] Optionally, in the power management module 20, the voltage division of each series resistor M is set to 0.1V with an accuracy of 1%.

[0078] For example, if the output voltage range of the power management module 20 is -15V to 15V, 300 resistors M can be connected in series between the first input terminal 21 and the second input terminal 22 of the power management module 20. Each resistor M divides the voltage by 0.1V, and the voltage division accuracy of the resistors M is 1%.

[0079] Figure 6 This is a flowchart illustrating a data processing method for an adapter board provided in an embodiment of this application.

[0080] This application also provides a data processing method for an adapter board, which can be applied to the adapter board 01 provided in the above embodiments. The structure and connection method of the adapter board 01 can be as follows: Figures 1-4 As shown. Figure 6 As shown, the data processing methods include:

[0081] Step S1: The conversion module 10 outputs the corresponding second voltage control signal VP2 according to the first voltage control signal VP1 it receives, and transmits it to the power management module 20.

[0082] Step S2: The power management module 20 outputs the test voltage Vt according to the second voltage control signal VP2 it receives.

[0083] The first voltage control signal VP1 and the second voltage control signal VP2 can be pulse signals with different parameters, such as the frequency and pulse width of the pulse signal. The first voltage control signal VP1 can be generated according to the voltage requirements of the terminal under test 03, and the second voltage control signal VP2 is a pulse signal that matches the power management module 20. The voltage management module 20 can respond to the second voltage control signal VP2 and output an accurate test voltage Vt.

[0084] In the data processing method provided in this application embodiment, the conversion module 10 can convert the first voltage control signal VP1 it receives into a second voltage control signal VP2 that matches the power management module 20, thereby controlling the power management module 20 to output a test voltage that meets the requirements. This can solve the problem of driver mismatch between the control module 02 and the power management module 20 produced by different manufacturers, improve the accuracy of the control module 02 controlling the power management module 20 to output the test voltage Vt, and thus help improve the accuracy of the test results.

[0085] Figure 7 A flowchart illustrating another data processing method for an adapter board provided in this application embodiment.

[0086] In one embodiment of this application, please continue to refer to Figure 2 The conversion module 10 includes a control unit 11 and an output unit 12. The input terminal of the control unit 11 is electrically connected to the external control module 02 and is used to receive the first voltage control signal VP1. The output terminal of the control unit 11 is electrically connected to the output unit 12.

[0087] like Figure 7 As shown, in step S1, the conversion module 10 outputs a corresponding second voltage control signal VP2 based on the first voltage control signal VP1 it receives, including:

[0088] Step S11: The control unit 11 outputs the parameters of the corresponding second voltage control signal VP2 according to the first voltage control signal VP1 it receives, and transmits them to the output unit 12.

[0089] Step S12: Output unit 12 outputs the corresponding second voltage control signal VP2 according to the parameters of the second voltage control signal VP2 it receives.

[0090] The parameters of the second voltage control signal VP2 can refer to information such as the frequency and pulse width of the second voltage control signal VP2.

[0091] In this embodiment, the control unit 11 can first obtain the parameters that the corresponding second voltage control signal VP2 should have based on the first voltage control signal VP1 it receives, and transmit them to the output unit 12; then, the output unit 12 outputs a specific second voltage control signal VP2 that meets the requirements in response to the parameters of the second voltage control signal VP2. In this way, the conversion module 10 can convert the first voltage control signal VP1 it receives into a second voltage control signal VP2 that matches the power management module 20.

[0092] Figure 8 A flowchart illustrating another data processing method for an adapter board provided in this application embodiment.

[0093] In one embodiment of this application, please continue to refer to Figure 4 The control unit 11 includes a detection unit 111, a selection unit 112 and a storage unit 113. The input terminal of the detection unit 111 is used to receive the first voltage control signal VP1, that is, the input terminal of the detection unit 111 is used to connect to the external control module 02.

[0094] The output terminal of the detection unit 111 is electrically connected to the selection unit 112, and the output terminal of the selection unit 112 is electrically connected to the output unit 12. The storage unit 113 is electrically connected to the selection unit 112, and the storage unit 113 stores a correspondence table between the parameters of the first voltage control signal VP1 and the parameters of the second voltage control signal VP2.

[0095] like Figure 8 As shown, in step S11 above, the control unit 11 outputs parameters of the corresponding second voltage control signal VP2 based on the first voltage control signal VP1 it receives, including:

[0096] Step S111: The detection unit 111 detects the parameters of the first voltage control signal VP1 it receives and transmits them to the selection unit 112.

[0097] Step S112: The selection unit 112 selects the parameters of the corresponding second voltage control signal VP2 from the correspondence table of the storage unit 113 according to the parameters of the first voltage control signal VP1 it receives, and outputs them.

[0098] The parameters of the first voltage control signal VP1 can be its frequency, pulse width, etc., and the parameters of the second voltage control signal VP2 can correspond to the same type of parameters of the first voltage control signal VP1.

[0099] For example, the frequency of the first voltage control signal VP1 corresponds to the frequency of the second voltage control signal VP2, and the pulse width of the first voltage control signal VP1 corresponds to the pulse width of the second voltage control signal VP2.

[0100] In this embodiment, the detection unit 111 first parses the parameters of the received first voltage control signal VP1 and transmits them to the selection unit 112. Then, the selection unit 112 retrieves the parameters of the corresponding second voltage control signal VP2 from the storage unit 113 based on the parameters of the first voltage control signal VP1 and transmits them to the output unit 12. The output unit 12 outputs a specific second voltage control signal VP2 that meets the requirements in response to the parameters of the second voltage control signal VP2. In this way, the conversion module 10 can convert the received first voltage control signal VP1 into a second voltage control signal VP2 that matches the power management module 20.

[0103] In the testing device 100, an adapter board 01 is provided, including a conversion module 10 and a power management module 20. The conversion module 10 converts the first voltage control signal VP1 output by the external control module 02 into a second voltage control signal VP2 that matches the power management module 20, thereby controlling the power management module 20 to output a test voltage that meets the requirements. This solves the problem of driver incompatibility between control modules 02 and power management modules 20 produced by different manufacturers, improves the accuracy of the control module 02 in controlling the power management module 20 to output the test voltage, and thus helps to improve the accuracy of the test results.

[0104] Figure 10 This is a schematic diagram of a testing system provided in an embodiment of this application.

[0105] like Figure 10 As shown in the embodiments, this application also provides a testing system 300, which includes a display module 200 and a testing adapter board 01 as provided in the above embodiments. The testing system 300 can be a screen testing system for the display module 200.

[0106] The display module 200 includes a display panel Pa and a driver chip DDIC. The driver chip DDIC is electrically connected to the input terminal of the conversion module 10 in the adapter board 01 and is used to provide a first voltage control signal VP1 to the conversion module 10. That is, the driver chip DDIC can be the control module 02 in the above embodiment.

[0107] The display panel Pa is electrically connected to the output terminal OUT of the power management module 20 in the adapter board 01. The power management module 20 transmits the test voltage Vt to the display panel Pa, meaning that the display panel Pa can be the terminal under test 03 in the above embodiment. The test voltage Vt output by the power management module 20 can be the PVDD, PVEE, AVDD, or other voltages required by the display panel Pa.

[0108] In the test system 300, the display requirements of the display panel Pa are provided to the driver chip DDIC. The driver chip DDIC outputs a first voltage control signal VP1 based on the image information and brightness information of the display panel Pa. The conversion module 10 converts the first voltage control signal VP1 output by the driver chip DDIC into a second voltage control signal VP2 that matches the power management module 20. The power management module 20 outputs the test voltage Vt required by the display panel Pa based on the second voltage control signal VP2. The display panel Pa responds to the test voltage Vt to display.

[0109] In this embodiment, the conversion module 10 can convert the first voltage control signal VP1 output by the driver chip DDIC into a second voltage control signal VP2 that matches the power management module 20, thereby controlling the power management module 20 to output a test voltage that meets the requirements. This can solve the problem of driver incompatibility between driver chips DDIC produced by different manufacturers and the power management module 20, improve the accuracy of the driver chip DDIC controlling the power management module 20 to output the test voltage, and thus help improve the accuracy of the test results.
