Description

Technical Field

[0001] This application relates to the field of electronic testing technology, and in particular to a display screen testing method, apparatus, computer equipment, storage medium, and computer program product. Background Technology

[0002] In the field of display screens, such as smartphones, tablets, and in-vehicle infotainment screens, touch sensors are directly integrated into the display. A touch sensor consists of transmitting electrodes (TX) and receiving electrodes (RX). These electrodes are arranged alternately on a plane, separated by an insulating layer. Their intersections form a coupling capacitor, and the entire screen is an array of hundreds or thousands of such capacitor nodes. When a finger (conductor) touches the screen, it disturbs the electric field at the intersection of the transmitting and receiving electrodes, thus altering the signal received by the receiving electrode. By scanning all the intersections of the transmitting and receiving electrodes, the location of the touch point can be calculated.

[0003] In the field of display screen testing, circuit boards are used to simulate the operation of touch screens. They send precise excitation signals to the transmit channels of the screen under test and receive the returned signals from the receive channels. By analyzing these signals, the normality of the screen's touch function is determined. In related technologies, as display screen sizes increase, the number of channels on the circuit board (e.g., 64 TX channels and 64 RX channels) remains fixed. However, the number of channels on the screen under test (e.g., 128 TX channels and 128 RX channels) exceeds the number of channels on the circuit board, making it impossible to complete the test in one go. Therefore, it is necessary to purchase larger circuit boards with more channels and higher density.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] The display screen testing method provided in this application embodiment can be applied to, for example, Figure 1In the application environment shown, processor 103 communicates with host computer 101. Processor 103 receives a test command for the touch channel of the display screen. It determines the test channel of at least one test board corresponding to the touch channel of the display screen 105. For example, the test channel includes a signal generation unit (SMU) and a signal switching unit (PAU). There is an information mapping relationship between the touch channel of the display screen and the test channel of at least one test board. This information mapping relationship is determined based on board combination information, which includes information about at least one test board corresponding to the display screen. Based on the test channel of the at least one test board, the test command is converted into a test signal, and the test signal is sent to the corresponding touch channel. Host computer 101 can be, but is not limited to, various desktop computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. Processor 103 includes, but is not limited to, ARM processors, x86 processors, and RISC-V processors.

[0053] In one embodiment, such as Figure 2 As shown, a display screen testing method is provided, which is applied to... Figure 1 Taking processor 103 as an example, the explanation includes the following steps:

[0054] Step S201: A test command is received for the touch channel of the display screen.

[0055] The display screen includes interactive touch screens, such as smartphones, tablets, and in-vehicle infotainment screens.

[0056] The touch channel of a display screen includes a transmitting channel and a receiving channel in the touch sensor. The touch sensor includes transmitting electrodes and receiving electrodes. The transmitting electrodes consist of a series of horizontally arranged, electrically connected conductive materials, each forming a transmitting channel. The receiving electrodes consist of a series of vertically arranged, electrically connected conductive materials, each forming a receiving channel. More specifically, a touch channel includes one transmitting channel and one corresponding receiving channel.

[0057] The test commands are used to detect the performance of the touch channel, such as whether there is a response, the response time, and other physical parameters. Optionally, the test commands can be sent by a host computer.

[0058] Step S203: Determine the test channel of at least one test board corresponding to the touch channel of the display screen; wherein, there is an information mapping relationship between the touch channel of the display screen and the test channel of at least one test board, and the information mapping relationship is determined based on board combination information, the board combination information including information of at least one test board corresponding to the display screen.

[0059] In one exemplary embodiment, the test instructions may include identification information of the touch channels of the display screen, such as touch channels A1 to A240. Based on the information mapping relationship between the touch channels and test channels of the display screen, the corresponding test channels are the code identifiers B1 to B120 of the test channels of test board 1, and the code identifiers B121 to B240 of the test channels of test board 2.

[0060] In another exemplary embodiment, the corresponding test board and the encoding identifier of the test channel of the test board can be determined based on the information mapping relationship between the touch channel of the display screen and the test channel of at least one test board, as well as the identification information of the touch channel of the display screen to be tested. Thus, the encoding identifier of the test channel of the test board can be directly written into the test command.

[0061] In this embodiment, the information mapping relationship between the touch channels of the display screen and the test channels of at least one test board can be obtained through board combination information. The board combination information includes information about at least one test board corresponding to the display screen. For example, the display screen includes 120 touch channels, and each test board also has 120 test channels. It is understood that one display screen can be tested using one test board. Based on this, an information mapping relationship can be set between the touch channels of one display screen and the test channels of one test board. In another example, the display screen includes 360 touch channels, and each test board also has 120 test channels. It is understood that one display screen is tested using three test boards. Based on this, an information mapping relationship can be set between the touch channels of one display screen and the test channels of the three test boards.

[0062] In an exemplary embodiment, the information mapping relationship between the touch channel of the display screen and the test channel of a test board can be implemented in the processor or in the host computer, and this embodiment does not limit this.

[0063] Step S205: Based on the test channel of the at least one test board, convert the test command into a test signal and send the test signal to the corresponding touch channel.

[0064] In a specific implementation, for example, the test instructions may include a portion of the touch channels of the display screen, such as touch channels 1 to 20. By receiving multiple test instructions, the testing of all touch channels of the display screen is completed. Alternatively, the test instructions may include all touch channels of the display screen, and the processor may test the touch channels of each portion of the display screen separately according to the test method.

[0065] In one exemplary embodiment, the test instructions may include a self-capacitance test, for example, testing the capacitance between the transmitting electrode and reference ground, or the capacitance between the receiving electrode and reference ground, of a single touch channel. Specifically, for example, signals are applied and measurements are taken sequentially for each transmitting or receiving electrode; if the capacitance value of a certain electrode is abnormally high, it may mean that it is short-circuited with other electrodes. In another exemplary embodiment, the test instructions may also include a mutual capacitance test, for example, sending test signals sequentially to the transmitting electrodes and simultaneously or sequentially measuring the signal strength received by all receiving electrodes to obtain a data matrix between the transmitting and receiving electrodes. For example, if the data at two adjacent intersection points is abnormally large or abnormally small, it may mean that there is a short circuit or open circuit between the transmitting and receiving electrodes at that point. It is understood that the touch function of the screen is subsequently determined by analyzing the signals received from the receiving channel RX.

[0066] In the above embodiments, the information mapping relationship between the touch channels of the display screen and the test channels of at least one test board is determined by the board combination information of the display screen and the test board. Therefore, when faced with a large number of touch channels on the display screen, it is not necessary to increase the number of test channels on the test board; testing of a large number of touch channels on a display screen can be achieved by combining at least one test board. Furthermore, by configuring the information mapping relationship between the touch channels of the display screen and the test channels of at least one test board, this application can flexibly test display screens with any number of touch channels, improving the scalability of the test board and reducing testing complexity.

[0067] In one embodiment, prior to receiving a test instruction for the touch channel of the display screen, the method further includes:

[0068] The system receives the board combination information of the display screen sent by the host computer; wherein the board combination information is obtained by determining the number of test boards required to test the display screen based on the first number of touch channels in the display screen and the second number of test channels in the test board.

[0069] Based on the board combination information, an information mapping relationship is constructed between the touch channel of the display screen and the test channel of the at least one test board.

[0070] In specific implementations, for example, when the first number of touch channels in the display screen is the same as the second number of test channels on the test board, the display screen and the test board can have a one-to-one correspondence. Another example is when the first number m of touch channels in the display screen is greater than the second number n of test channels on the test board, the test board corresponding to the display screen can be the integer part of m / n plus 1. For example, if the display screen has 240 touch channels and the test board has 120 test channels, then one display screen can correspond to two test boards. As another example, if the display screen has 245 touch channels and the test board has 120 test channels, then one display screen can correspond to three test boards.

[0071] In one exemplary embodiment, display screen A has 240 touch channels, with corresponding identification information from A1 to A240. The board combination information includes test board B and test board C corresponding to display screen S, and each test board has 120 test channels. For test board B, the corresponding test channel codes are numbers 1 to 120; for test board C, the corresponding test channel codes are numbers 121 to 240. A mapping relationship is established between the identification information of the touch channels of display screen A and the code codes of the test boards. For example, A1 corresponds to number 1; A2 corresponds to number 2; A3 corresponds to number 3, etc.

[0072] In the above embodiments, the board combination information of the display screen sent by the host computer is received. The board combination information is obtained by determining the number of test boards required to test the display screen based on a first number of touch channels in the display screen and a second number of test channels in the test boards. Based on the board combination information, an information mapping relationship between the touch channels of the display screen and the test channels of at least one test board is constructed. This allows for convenient and rapid determination of the information mapping relationship between the touch channels of each display screen and the test channels of at least one test board.

[0073] In one embodiment, the mapping relationship between the touch channel of the display screen and the test channel of the at least one test board includes:

[0074] If the first quantity is greater than the second quantity, the coding order of the at least one test board is determined.

[0075] Based on the encoding order, the encoding identifier of the target test channel in the at least one test board is determined.

[0076] Construct a mapping relationship between the encoding identifier of the target test channel and the identification information of the touch channel of the display screen.

[0077] In the specific implementation process, for example, the number of touch channels of display screen S is 360, the number of test channels of test board a is 80, the number of test channels of test board b is 120, and the number of test channels of test board c is 160. Since the number of touch channels of the display screen is greater than the number of test channels of any test board, the board combination information can be that the test boards corresponding to display screen S are test board a, test board b, and test board c. For example, the encoding order of the test boards can be randomly set, for example, encoding order 1 is: test board a, test board b, and test board c. Or, for example, encoding order 2 is: test board b, test board c, and test board a. Optionally, encoding order 1 is selected. Through this encoding order, the encoding identifier of test board a is first determined, for example, number 1 to 80; then the encoding identifier of test board b is determined, for example, number 81 to 200; finally, the encoding identifier of test board c is determined, for example, number 201 to 360.

[0078] In the above embodiments, the encoding identifier of the target test channel in the at least one test board is determined based on the encoding order. A mapping relationship is established between the encoding identifier of the target test channel and the identification information of the touch channel of the display screen. This allows for convenient and rapid generation of the encoding identifier in the test board.

[0079] In one embodiment, the display screen includes multiple screens, and the test channel based on the at least one test board converts the test command into a test signal and sends the test signal to the corresponding touch channel, including:

[0080] Create a new number of child threads corresponding to the number of display screens; wherein, each child thread corresponds one-to-one with a display screen.

[0081] Based on the sub-thread and the corresponding test channel of at least one test board, the test instruction is converted into a test signal and the test signal is sent to the corresponding touch channel.

[0082] In the specific implementation process, refer to Figure 3As shown, when there are three display screens, three sub-threads can be created, such as sub-thread 1, sub-thread 2, and sub-thread 3, corresponding to screen 1, screen 2, and screen 3 respectively. Sub-thread 1 sends the test signal to the test channel of the test board corresponding to display screen 1, and converts the test command into a test signal based on this test channel. Sub-thread 2 sends the test signal to the test channel of the test board corresponding to display screen 2, and converts the test command into a test signal based on this test channel. Sub-thread 3 sends the test signal to the test channel of the test board corresponding to display screen 3, and converts the test command into a test signal based on this test channel.

[0083] In the above embodiments, by establishing sub-threads corresponding to the display screen, each sub-thread performs parallel testing, which helps improve the testing efficiency of the display screen. Furthermore, when the test instructions for the display screen are the same, multiple sub-threads can share a set of test instructions, thereby reducing the amount of code in the test instructions.

[0084] In one embodiment, the test channel of the test board includes a signal generation unit and a signal switching unit. Converting the test command into a test signal and sending the test signal to the corresponding touch channel includes:

[0085] Based on the signal switching unit, the target touch channel corresponding to the test command is activated.

[0086] The signal generating unit converts the test command into a test signal and sends the test signal to the target touch channel.

[0087] In the specific implementation process, refer to Figure 1 As shown, the test board includes a signal generation unit (SMU) and a signal switching unit (PAU). The SMU is responsible for outputting and acquiring the test signal, while the PAU is responsible for switching the test signal transmission channel and the receiving channel.

[0088] In one exemplary embodiment, the test instruction includes the target touch channel for the current test on the display screen, for example, touch channels 1-20. Exemplarily, the remaining 21 to 240 touch channels can be disconnected and touch channels 1-20 can be connected via a signal switching unit. In another exemplary embodiment, the test instruction is converted into a test signal by a signal generation unit (SMU) and the test signal is sent to touch channels 1-20.

[0089] In the above embodiment, the signal switching unit connects the target touch channel corresponding to the test command. The signal generating unit converts the test command into a test signal and sends the test signal to the target touch channel. The signal switching unit and the signal generating unit work together to improve the diversity of signal testing.

[0090] In one embodiment, the test command includes at least one of the following: DC test command, AC test command, and aging test command.

[0091] In specific implementation, DC test commands may include the number of test channels, channel number, resistance range, delay time, etc., and return at least one of the measured resistance values. AC test commands may include at least one of the following: the number of test channels, channel number, AC voltage amplitude, frequency, number of sampling periods, gain, measurement type, etc., and return the sampling points of the test waveform, and whether to return a capacitance value or a voltage value depending on the measurement type. The aging test command may include at least one of the following: the number of test channels, channel number, positive and negative voltage values, duration, etc.

[0092] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
