[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first message may be referred to as a second message, and similarly, a second message may be referred to as a first message. Both the first message and the second message are messages, but they are not the same message.

[0027] Usually, before assembling the terminal screen with the terminal motherboard and other devices, the screen to be assembled will be tested for screen lighting using a special fixture on the production line to ensure that the display and touch functions of the screen unit to be assembled are normal, thereby preventing problems with defective rework after the screen is assembled. When performing screen lighting detection on the screen to be assembled, a mainboard with normal display is fastened with a pin using the fixture on the production line. At the same time, in order to facilitate the fastening and disassembly of the screen, a hot-swappable power supply board and an extension cable are added to perform screen lighting detection on the screen to be assembled. However, after adding the extension cable, the insertion loss of the mobile industry processor interface (MIPI) channel of the screen to be assembled becomes larger, the signal quality becomes worse, the screen frame rate and MIPI transmission rate are reduced, and the data throughput of the entire channel is reduced. In particular, when the screen module to be tested is a folding screen module, the insertion loss of the MIPI channel is particularly obvious. In this way, when the default formal production software of the whole machine is flashed into the fastened mainboard to perform screen lighting detection on the screen module, the screen module will experience screen flickering and flower screen, but after the screen module is installed in the whole machine environment, the screen module display is normal again. In this way, the fixture on the production line cannot play the role of selecting the screen module. Based on this, a special screen-pointing software is proposed for the fixture on the production line to perform screen lighting test on the screen module, ensuring that the normal screen module can display normally when the fixture is used for detection, so that the detection fixture on the production line can achieve the function of selecting bad screens. However, the official software and the screen-pointing software in the terminal are two different versions of software, and the screen display parameters of the two are not the same and cannot be compatible. The development of these two different versions of software requires separate debugging, and the official software and the screen-pointing software need to be installed on different motherboards, that is, the screen-pointing software is installed on the motherboard for testing the screen module, and the official software is installed on the motherboard for assembling the terminal. The official software and the screen-pointing software need to be maintained separately on different motherboards, thereby increasing the production line maintenance cost, so that when the above-mentioned screen-pointing software is used to perform screen lighting detection on the screen module of the terminal, there is a problem of high software maintenance cost. Based on this, the present application proposes a detection circuit, a detection system, a detection method, a motherboard and a readable storage medium, which is intended to solve the problem of high software maintenance cost when the screen-pointing software adapted to the detection fixture on the production line is used to perform screen lighting detection on the screen module of the terminal.

[0028] In one embodiment, Figure 1 As shown, a detection circuit 01 is provided, comprising: a mainboard 10 and a power supply 20, the mainboard 10 comprising a processor 101, the power supply 20 being respectively connected to the target pin of the screen module to be detected and the processor 101, and the target pin of the screen module is also connected to the processor 101; the processor 101 is used to detect the screen module by calling the target screen display parameters corresponding to the level signal according to the level signal output by the target pin.

[0029] The screen module to be tested is the screen module before being assembled with the terminal's mainboard and other devices. The screen module to be tested can be composed of any of a variety of electronic screens. After being assembled with the terminal's mainboard and other devices, the screen module to be tested can be used to provide visual content display. Optionally, the screen module to be tested in this embodiment can be a folding screen module, or a sliding screen module, etc., which is not limited in this embodiment.

[0030] Optionally, in this embodiment, the target pin of the screen module to be detected can be a physical signal line led out from the screen module to be detected. Since the power supply 20 of the detection circuit 01 is connected to the target pin of the screen module to be detected, the current can be input to the target pin of the screen module to be detected through the power supply 20. The target pin of the screen module to be detected can form different loops when the screen module is connected to the detection fixture and when the screen module is not connected to the detection fixture, so that the target pin can generate different level signals based on these two different connection conditions, and the processor 101 can detect the different level signals generated by the target pin. It should be noted that the detection fixture in this embodiment can be any existing fixture for detecting the screen module, but it is necessary to ensure that one end of the detection fixture is grounded so that the target pin of the screen module to be detected can generate different level signals when the screen module to be detected is connected to the detection fixture. This embodiment does not limit the specific type and structure of the detection fixture.

[0031] In this embodiment, the main board 10 is the largest circuit board in the terminal, on which the main circuit systems constituting the terminal are installed. Optionally, the screen display parameters of the screen-lighting software used when performing screen lighting detection on the screen module and the screen display parameters of the formal software in the terminal can be stored in advance on the main board 10, that is, the screen display parameters of the screen-lighting software and the screen display parameters of the formal software are normalized, and the screen display parameters of the screen-lighting software and the screen display parameters of the formal software are stored on the same main board.

[0032] Further, it can be understood that the circuit formed when the screen module to be detected is connected to the detection fixture is different from the circuit formed when the screen module to be detected is not connected to the detection fixture. Therefore, the level signal of the target pin output collected by the processor 101 when the screen module to be detected is connected to the detection fixture is different from the level signal of the target pin output collected when the screen module to be detected is not connected to the detection fixture. Therefore, the processor 101 can determine whether the screen module to be detected is connected to the detection fixture based on the level signal output by the target pin of the screen module to be detected, and call the target screen display parameters corresponding to the level signal output by the target pin to detect the screen module to be detected. For example, if the processor 101 determines that the screen module to be detected is connected to the detection fixture based on the level signal output by the target pin, the target screen display parameters corresponding to the level signal output by the target pin can be the screen display parameters corresponding to the screen-clicking software, and then the screen module to be detected is detected through the screen display parameters; if the processor 101 determines that the screen module to be detected is not connected to the detection fixture based on the level signal output by the target pin, the target screen display parameters corresponding to the level signal output by the target pin can be the screen display parameters corresponding to the correct version, and then the display screen of the screen module is controlled through the screen display parameters.

[0033] Optionally, in this embodiment, the detection result of the screen module to be detected may be that the display and touch functions of the screen module are normal, or it may be that the display and trigger functions of the screen module are abnormal, etc., and this embodiment does not limit this. It is understandable that if the processor 101 detects that the detection result of the screen module to be detected is that the display and trigger functions of the screen module are abnormal, then the processor 101 can further generate prompt information to remind production personnel that the screen module to be detected needs to be fully processed before it can be assembled with the terminal's mainboard and other devices, or the generated prompt information can be a prompt information used to remind production personnel that the screen module to be detected has a large loss and cannot be used normally, and the screen module can be discarded, etc. This embodiment does not limit the detailed content of the prompt information generated based on the detection result. Optionally, in the present embodiment, a signal light connected to the processor 101 may be provided in the detection circuit, and prompt information may be displayed by the color of the signal light. For example, if the color of the signal light is red, it may indicate that the detection result of the screen module to be detected is that the display and trigger functions of the screen module are abnormal; if the color of the signal light is yellow, it may indicate that the detection result of the screen module to be detected is that the display and trigger functions of the screen module are normal.

[0034] The above-mentioned detection circuit includes a mainboard and a power supply. The mainboard includes a processor. The power supply is respectively connected to the target pin of the screen module to be detected and the processor. The target pin of the screen module is also connected to the above-mentioned processor. The processor can call the target screen display parameters corresponding to the level signal output by the target pin according to the level signal output by the target pin to detect the screen module. Since the screen display parameters of the official version and the screen display parameters of the dot screen version during the test are normalized in the detection circuit, the processor can call the target screen display parameters corresponding to the level signal output by the target pin according to the level signal output by the target pin. When compiling and maintaining the software, it only needs to be compiled and maintained on the same mainboard, without the need to compile and maintain different software on two mainboards respectively, saving the cost of software development and maintenance.

[0035] On the basis of the above embodiment, the specific process of the processor calling the target screen display parameter corresponding to the level signal output by the target pin according to the level signal output by the target pin is described in detail in this embodiment. In one embodiment, the processor 101 is used to call the first screen display parameter to control the display screen of the screen module when the target pin outputs the first level; or, when the target pin outputs the second level, call the second screen display parameter to control the display screen of the screen module; wherein the second level is higher than the first level; and the display performance of the first screen display parameter is lower than the display performance of the second screen display parameter.

[0036] In this example, see Figure 2 When the screen module to be detected is connected to the detection fixture, since the detection fixture end is grounded, the current output by the power supply 20 will not flow to the target pin of the screen module to be detected, so that the target pin will generate a low level when the screen module to be detected is connected to the detection fixture, that is, the above-mentioned first level; when the screen module to be detected is not connected to the detection fixture, the current output by the power supply 20 will flow to the target pin of the screen module to be detected, so that the target pin will generate a high level when the screen module to be detected is not connected to the detection fixture, that is, the above-mentioned second level.

[0037] Further, as an optional implementation, when the screen module to be tested is connected to the detection fixture, that is, when the processor 101 detects that the target pin outputs the first level, the processor 101 can call the first screen display parameter of the point screen version to control the display screen of the screen module and detect the display and trigger functions of the screen module. As another optional implementation, when the screen module to be tested is not connected to the detection fixture, that is, when the processor 101 detects that the target pin outputs the second level, the processor 101 can call the second screen display parameter of the official version to control the display screen of the screen module. It can be understood that since the first screen display parameter of the point screen version is used to detect the display and triggering functions of the screen module, it can ensure that the screen module can display normally and does not require the display quality of the screen module to be relatively high at this time. The first screen display parameter with relatively low frame rate and frame speed can be used. The second screen display parameter of the official version is used for displaying visual content during the use of the terminal in the terminal. It is necessary to ensure the quality and clarity of the displayed picture. Therefore, the display performance of the first screen display parameter of the point screen version in this embodiment can be lower than the display performance of the second screen display parameter of the official version.

[0038] In this embodiment, the processor can call the first screen display parameter to control the display screen of the screen module when the target pin outputs the first level, and call the second screen display parameter to control the display screen of the screen module when the target pin outputs the second level. By calling different screen display parameters to control the display screen of the screen module when the target pin outputs different levels, the screen display parameters of the dot screen version and the screen display parameters of the formal version can be normalized, which facilitates the unified management of the screen display parameters of the dot screen version and the screen display parameters of the formal version, thereby reducing the cost of software maintenance when detecting the screen module.

[0039] Based on the above embodiment, as an optional implementation mode, Figure 3 As shown, the detection circuit 01 further includes a resistor 30 , which is connected to the power supply 20 , the screen module and the processor 101 respectively.

[0040] In this embodiment, the detection circuit 01 also includes a resistor 30. For further information, please continue to refer to Figure 3As an optional implementation, when the screen module to be detected is connected to the detection fixture, the current output by the power supply 20 can flow to the ground terminal of the detection fixture after passing through the resistor 30. At this time, no current will pass through the target pin of the screen module to be detected, and the target pin of the screen module will output the above-mentioned first level. As another optional implementation, when the screen module is not connected to the detection fixture, the current output by the power supply 20 will flow to the screen module to be detected after passing through the resistor 30. At this time, the target pin of the screen module will output the above-mentioned second level. It can be understood that in the above-mentioned detection circuit, since the current output by the power supply 20 first passes through the resistor 30, the size of the power supply output current can be limited by the resistor 30, and the resistor 30 plays a role in buffering the power supply output current, thereby avoiding the impact on the entire detection circuit when the current output by the power supply 30 is too large, thereby causing the occurrence of problems such as detection circuit failure.

[0041] In this embodiment, the detection circuit also includes a resistor, which can limit the magnitude of the power supply output current, thereby avoiding the impact of excessive power supply output current on the detection circuit, thereby avoiding the occurrence of problems such as detection circuit failure due to excessive power supply output current.

[0042] In some scenarios, it may be necessary to change different scenarios when testing the screen module to be tested. To test in different scenarios, the detection circuit for testing the screen module to be tested needs to be smaller in size and be able to be flexibly applied to a variety of different test scenarios. Based on the above embodiment, as an optional implementation, the processor 101 and the power supply 20 are both integrated on the mainboard 10.

[0043] In this embodiment, as an optional implementation, since the mainboard 10 is an indispensable device in the entire detection circuit, and the area on the mainboard 10 is usually large, other devices can be integrated on the mainboard for integrated setting. In this embodiment, in order to reduce the volume occupied by the detection circuit, as an optional implementation, the processor 101 and the power supply 20 can be integrated on the mainboard 10. However, it can be understood that, in addition to the implementation of this embodiment, the power supply 20 can also be a separate external power supply, which can be independently set outside the mainboard, rather than integrated on the mainboard, as long as it is ensured that the power supply 20 can be used to power the detection circuit 01. It can be understood that the above two implementations can be selected according to specific actual needs when they are specifically selected. When the volume of the detection circuit 01 is required to be small, the power supply 20 can be integrated on the mainboard 10. When there is no requirement for the volume of the detection circuit 01, the above two implementations can be used, as long as it can be ensured that the power supply 20 can be used to power the detection circuit.

[0044] In this embodiment, the processor and power supply in the detection circuit are integrated on the main board, which can greatly reduce the volume occupied by the detection circuit, making the detection circuit more flexible and facilitating screen lighting detection of the detection screen module in practice.

[0045] In one embodiment, Figure 4 As shown, a detection system is provided, which includes the detection circuit described in the above embodiment and a screen module to be detected.

[0046] In this embodiment, the detection system includes the detection circuit described in the above embodiment and the screen module to be detected. In this way, after the screen module to be detected is connected to the detection circuit described in the above embodiment in the detection system, when the screen module to be detected is also connected to the detection fixture, the detection circuit described in the above embodiment can be used to perform screen lighting detection on the screen module to be detected, so as to detect the display and triggering functions of the screen module to be detected, and whether the screen module is damaged or cannot display defects can be detected in time, thereby avoiding the problem of defective rework after the screen module is assembled with the terminal.

[0047] The above-mentioned detection system includes a detection circuit and a screen module to be detected. By connecting the screen module to be detected with the detection circuit, when the screen module to be detected is connected to the detection fixture, the detection circuit can promptly perform screen lighting detection on the screen module to be detected to ensure that the display and triggering functions of the screen module are normal, thereby avoiding the problem of defective rework after the screen module is assembled with the terminal.

[0048] In one embodiment, Figure 5 As shown, a detection method is provided, which is applied to the detection circuit in the above embodiment, and the method includes:

[0049] S201, obtaining the level signal output by the target pin.

[0050] S202: According to the level signal, call the target screen display parameters corresponding to the level signal to detect the screen module to be detected.

[0051] The screen module to be tested is the screen module before being assembled with the terminal, and the screen module to be tested can be composed of any of a variety of electronic screens, and the screen module to be tested can be used to provide visual content display. Optionally, in this embodiment, the screen module to be tested can be a folding screen module, or a sliding screen module.

[0052] Optionally, in the present embodiment, the target pin of the screen module to be detected can be a physical signal line led out from the screen module to be detected. Since the power supply of the detection circuit is connected to the target pin of the screen module to be detected, the power supply can input current to the target pin of the screen module to be detected, and the target pin can generate different level signals when the screen module is connected to the detection fixture and when the screen module is not connected to the detection fixture. It should be noted that the detection fixture in the present embodiment can be any existing fixture for detecting the screen module, but it is necessary to ensure that one end of the detection fixture is grounded so that the target pin of the screen module to be detected can generate different level signals when the screen module to be detected is connected to the detection fixture. The present embodiment does not limit the specific type and structure of the detection fixture.

[0053] In this embodiment, the main board is the largest circuit board in the terminal, on which the main circuit systems constituting the terminal are installed. The screen display parameters of the screen-pointing software used for screen lighting detection on the screen module and the screen display parameters of the formal software in the terminal can be pre-stored, that is, the screen display parameters of the screen-pointing software and the screen display parameters of the formal software are normalized, and the screen display parameters of the screen-pointing software and the screen display parameters of the formal software are stored on the same mainboard.

[0054] Further, it can be understood that the circuit formed when the screen module to be detected is connected to the detection fixture is different from the circuit formed when the screen module to be detected is not connected to the detection fixture. Therefore, the level signal of the target pin output collected by the processor when the screen module to be detected is connected to the detection fixture is different from the level signal of the target pin output collected when the screen module to be detected is not connected to the detection fixture. Therefore, the processor can determine whether the screen module to be detected is connected to the detection fixture based on the level signal output by the target pin of the screen module to be detected, and call the target screen display parameters corresponding to the level signal output by the target pin to detect the screen module to be detected. For example, if the processor determines that the screen module to be detected is connected to the detection fixture based on the level signal output by the target pin, the target screen display parameters corresponding to the level signal output by the target pin may be the screen display parameters corresponding to the screen-clicking software, and then the screen module to be detected is detected through the screen display parameters; if the processor determines that the screen module to be detected is not connected to the detection fixture based on the level signal output by the target pin, the target screen display parameters corresponding to the level signal output by the target pin may be the screen display parameters corresponding to the correct version, and then the screen module to be detected is detected through the screen display parameters.

[0055] Optionally, in the present embodiment, the detection result of the screen module to be detected may be that the display and touch functions of the screen module are normal, or it may be that the display and trigger functions of the screen module are abnormal, etc., and the present embodiment does not limit this. It is understandable that if the processor detects that the detection result of the screen module to be detected is that the display and trigger functions of the screen module are abnormal, a prompt message may be further generated to remind the production personnel that the screen module to be detected needs to be fully processed before it can be assembled with the terminal. Alternatively, the generated prompt message may be a prompt message used to remind the production personnel that the screen module to be detected has a large loss and cannot be used normally, and the screen module can be discarded, etc. The present embodiment does not limit the detailed content of the prompt message generated based on the detection result.

[0056] The above detection method is applied to a detection circuit, which includes a mainboard and a power supply. The mainboard includes a processor. The power supply is respectively connected to the target pin of the screen module to be detected and the processor. The target pin of the screen module is also connected to the above processor. The processor can call the target screen display parameters corresponding to the level signal output by the target pin to detect the screen module according to the level signal output by the target pin. Since the screen display parameters of the official version and the screen display parameters of the dot screen version during the test are normalized in the detection circuit, the processor can call the target screen display parameters corresponding to the level signal output by the target pin according to the level signal output by the target pin. When compiling and maintaining the software, it only needs to be compiled and maintained on the same mainboard, without the need to compile and maintain different software on two mainboards respectively, saving the cost of software development and maintenance.
