[0057] To make the purpose, technical scheme and effect of the application more clear and explicit, the application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application, and are not used to limit the application.

[0058] The application provides a wire encryption verification method for display module testing. The method can effectively protect the wire and the connection mode thereof and avoid being imitated by others. In a specific application, the wire encryption verification method for display module testing first acquires characteristic information of an accessed wire, determines an encryption verification program corresponding to the characteristic information based on the characteristic information, and then sends ciphertext information corresponding to the encryption verification program to an encryption chip arranged on the wire. Finally, the wire encryption verification method for display module testing receives feedback ciphertext fed back by the encryption chip based on the ciphertext information, determines an encryption verification result of the wire according to the feedback ciphertext, and controls a test process for the wire according to the encryption verification result. The wire encryption verification method for display module testing acquires the characteristic information of the accessed wire, acquires the corresponding encryption verification program, and performs encryption verification on the wire based on the preset encryption chip. Only when the encryption verification is passed, the test process of the display module is performed, thereby effectively protecting the wire and avoiding the risk of imitation of the wire and the connection mode thereof.

[0059] Exemplary method

[0060] The wire encryption verification method for display module testing can be applied to a test device, which can be a computer, a mobile phone, a tablet computer or other intelligent product terminal. The test device implements the steps of the wire encryption verification method for display module testing. In a specific application, the test device of the application is connected through a corresponding wire when testing a display module. Specifically, as shown in FIG. 1, the wire encryption verification method for display module testing includes the following steps: Figure 1

[0061] Step S100, acquiring characteristic information of an accessed wire, and determining an encryption verification program corresponding to the characteristic information based on the characteristic information, wherein the wire is used for testing a display mode.

[0062] In order to protect the wire and prevent others from maliciously using an imitated wire to test a display module, the application first acquires the characteristic information of the wire accessed on the test device. Since the wire is used for testing a display mode, the characteristic information reflects the type of the wire, such as reflecting which item on the screen of the display module is tested. After the characteristic information of the wire is determined, the application also needs to determine an encryption verification program corresponding to the characteristic information according to the characteristic information. The encryption verification program in the application corresponds to the characteristic information of the wire, and thus the encryption verification program can be used to verify the wire.

[0063] In an implementation mode, when the encryption verification program is acquired, the application includes the following steps:​

[0064] Step S101, listen to the access state information of the preset flat cable interface;

[0065] Step S102, if the access state information is that the flat cable is removed, exit the test procedure;

[0066] Step S103, if the access state information is that the flat cable is accessed, obtain the characteristic information of the accessed flat cable;

[0067] Step S104, obtain the flat cable ID corresponding to the characteristic information, and determine the encryption characteristic corresponding to the flat cable ID according to the flat cable ID;

[0068] Step S105, obtain the encryption verification program corresponding to the encryption characteristic.

[0069] Specifically, after the test device of the embodiment is started, first, the access state information of the preset flat cable interface on the test device is listened to. The access state information reflects whether the flat cable is accessed in the flat cable interface on the test device. If it is listened that the access state information is that the flat cable is removed, it indicates that the flat cable on the flat cable interface has been removed at this time, so the detection procedure of the display module can be directly exited. If it is listened that the access state information is that the flat cable is accessed, it indicates that the flat cable has been accessed on the flat cable interface at this time, so the test procedure of the display module can be entered, and the encryption verification of the accessed flat cable can be started.

[0070] The test device in the embodiment can be provided with a plurality of flat cable interfaces, each of which corresponds to different test functions. Therefore, when the display module is tested, the corresponding flat cable is accessed on the corresponding flat cable interface, and the flat cable itself also corresponds to the test function, for example, when the display effect of the screen of the display module needs to be tested, the corresponding flat cable needs to be accessed on the corresponding flat cable interface. Based on this, the test terminal of the embodiment can determine the characteristic information of the flat cable accessed on the flat cable interface by identifying and reading the characteristic of the accessed flat cable. Specifically, the test terminal of the embodiment can determine which flat cable interface the accessed flat cable is accessed on by listening to the access event, further determine what function of the display module the flat cable interface is used for testing, and then determine the characteristic information of the corresponding flat cable, that is, determine the type of the flat cable.

[0071] When the characteristic information of the flat cable is determined, the embodiment can acquire the flat cable ID corresponding to the characteristic information, the flat cable ID being identification information of the flat cable, determine the encryption characteristic corresponding to the flat cable ID based on the flat cable ID, and then acquire the encryption check program corresponding to the encryption characteristic. That is, in the embodiment, the flat cable ID corresponding to each type of characteristic information and the encryption check program corresponding to each flat cable ID are preconfigured, so that the corresponding flat cable ID can be determined based on the characteristic information, and the corresponding encryption check program is loaded based on the flat cable ID, and the whole process is convenient and fast. The acquired encryption check program can be used for encryption check of the flat cable.

[0072] In step S200, based on the encryption check program, the ciphertext information corresponding to the encryption check program is sent to the encryption chip provided on the flat cable.

[0073] When the encryption check program is determined, the test equipment of the embodiment can send the corresponding ciphertext information to the encryption chip (encryption IC) preconfigured on the flat cable, and the ciphertext information is generated based on the encryption check program. The encryption chip of the embodiment is preconfigured on each flat cable to realize encryption check for each flat cable.

[0074] In an implementation manner, when the ciphertext information corresponding to the encryption check program is sent in the embodiment, the following steps are included:

[0075] In step S201, an encryption mode corresponding to the encryption check program is acquired.

[0076] In step S202, the ciphertext information is randomly generated according to the encryption mode, and the ciphertext information is sent to the encryption chip provided on the flat cable.

[0077] Specifically, the encryption mode corresponding to the encryption check program is first acquired in the embodiment, the encryption mode corresponding to the determined encryption check program, and the encryption modes corresponding to different encryption check programs are different, so the encryption mode corresponding to the encryption check program is first acquired in the embodiment. Then, the ciphertext information is randomly generated according to the encryption mode, and the ciphertext information is sent to the encryption chip provided on the flat cable. When the encryption chip receives the ciphertext information, the feedback ciphertext is calculated based on the encryption characteristic of the encryption chip itself, and then the feedback ciphertext is sent to the test equipment.

[0078] In step S300, the feedback ciphertext fed back by the encryption chip based on the ciphertext information is received, the encryption check result of the flat cable is determined according to the feedback ciphertext, and the test process for the flat cable is controlled according to the encryption check result.

[0079] The test equipment receives the feedback ciphertext fed back by the encryption chip, and determines the encryption check result of the flat cable according to the feedback ciphertext. The encryption check result of the embodiment reflects whether the flat cable passes the test. Therefore, the test flow of the flat cable can be controlled according to the encryption check result.

[0080] In step S301, after the ciphertext information is sent to the encryption chip arranged on the flat cable, the check ciphertext is generated based on the encryption characteristics of the encryption chip.

[0081] In step S302, the check ciphertext is compared with the feedback ciphertext. If the check ciphertext is the same as the feedback ciphertext, it is determined that the encryption check result is encryption check pass.

[0082] In step S303, if the check ciphertext is not the same as the feedback ciphertext, it is determined that the encryption check result is encryption check fail.

[0083] Specifically, after the ciphertext information is sent to the encryption chip arranged on the flat cable, the test equipment generates the check ciphertext based on the encryption characteristics of the encryption chip. The check ciphertext is generated by the test equipment itself. Then, the test equipment compares the generated check ciphertext with the feedback ciphertext. If the check ciphertext is the same as the feedback ciphertext, it indicates that the encryption mode of the encryption IC to the flat cable is the same as the encryption mode of the test equipment to the flat cable, and the encryption effect is also the same. Therefore, it is determined that the encryption check result is encryption check pass. If the check ciphertext is not the same as the feedback ciphertext, it indicates that the encryption mode of the encryption IC to the flat cable is not the same as the encryption mode of the test equipment to the flat cable, and the encryption effect is also not the same. Therefore, it is determined that the encryption check result is encryption check fail.

[0084] When it is determined that the encryption check result is encryption check pass, the test flow is controlled. At this time, the test equipment can test the display module by using the flat cable. If the encryption check result is encryption check fail, the test equipment exits the test flow and outputs prompt information. The test personnel can perform the next processing according to the prompt information displayed on the test equipment. Of course, in another implementation manner, the encryption chip of the embodiment can also judge the encryption check result of the flat cable based on the ciphertext information sent by the test equipment, that is, the encryption chip itself judges whether it is compliant, and then feeds back the encryption check result to the test equipment.

[0085] In summary, the embodiment first acquires characteristic information corresponding to an accessed flat cable, and determines an encryption check procedure corresponding to the characteristic information based on the characteristic information, wherein the flat cable is used for testing a display mode. Then, based on the encryption check procedure, ciphertext information corresponding to the encryption check procedure is sent to an encryption chip arranged on the flat cable. Finally, feedback ciphertext fed back by the encryption chip based on the ciphertext information is received, and an encryption check result of the flat cable is determined according to the feedback ciphertext, and a test flow for the flat cable is controlled according to the encryption check result. The application acquires characteristic information of an accessed flat cable, acquires a corresponding encryption check procedure, and performs encryption check on the flat cable based on a preset encryption chip. Only when the encryption check passes, the test flow of the display module is performed, thereby effectively protecting the flat cable and avoiding the risk of copying and imitating the flat cable and the connection mode thereof.
