Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to the technical field of display screen testing, and in particular to a display module testing method, device, equipment and storage medium. Background Art
[0002] Electronic devices equipped with display modules, such as mobile phones, often have a sleep wake-up function in actual practical scenarios. This means that when the mobile phone is not used for a long time, the screen will automatically enter the sleep detection (lpwg) state to save power. When the consumer needs to turn on the screen again, just double-click the screen to wake it up. Sleep wake-up (lpwg mode) is the Driver IC (in the Incell display module, the Driver IC and the touch IC are the same IC, called TDDIIC) controlling the display module to enter the lpwg timing. When a gesture touch is detected, the display screen will be powered on and woken up. If the timing of the lpwg mode is incorrect, there will be display effect problems after waking up, such as horizontal stripes at the bottom of the low grayscale screen.
[0003] Currently, the detection of a single display module can only test whether the module TP performance meets the standards. It cannot enter the sleep state and the sleep detection (lpwg) state, and cannot test the display module effect after waking up, and thus cannot guarantee the performance of the touch display module shipped from the factory.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0048] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.
[0049] In one embodiment, Figure 1 The flowchart of the display module testing method provided for an embodiment of the present invention can be applicable to the scenario of testing the sleep gesture wake-up mode of the display module. The method can be executed by a display module testing device, which can be implemented in software and / or hardware and can be integrated on a terminal device.
[0050] First, refer to Figure 1 , an embodiment of the present invention provides a method for testing a display module, comprising:
[0051] S100, lighting up and configuring the display module to be tested, so that the TFT of the display module to be tested generates a touch scanning signal;
[0052] S200, entering the sleep gesture wake-up mode and performing a sleep wake-up test;
[0053] S300, detecting the display screen effect of the display module to be tested after the test;
[0054] S400, if the display screen is abnormal, determining that the display module to be tested has failed the test;
[0055] S500: If the display screen is normal, it is determined that the display module to be tested has passed the test.
[0056] Among them, since the single display module to be tested cannot realize the complete functions of the whole machine and cannot perform normal touch operations, it is necessary to light up and configure the display module to be tested so that the TFT of the display module to be tested generates a touch scanning signal, that is, simulates the normal touch display function, so that it can be subjected to a sleep wake-up test.
[0057] Preferably, in the embodiment of the present invention, based on Figure 6 The test fixture shown is used to carry out the test process of the display module to be tested.
[0058] The test fixture includes a base 1 and a test drive board 2, the test drive board 2 is arranged on the base 1, the test drive board 2 includes a driver IC 3 and a plurality of adapter FPCs 4, and the plurality of adapter FPCs 4 are used to connect the display module to be tested. When performing a sleep wake-up test on the display module to be tested, the test drive board 2 simulates the whole machine function to configure the display module to be tested, so that it has a touch display function, and performs a sleep gesture wake-up mode test.
[0059] Wherein, the transfer FPC4 is set to 1-8 strips, which can realize the simultaneous detection of 1-8 display modules;
[0060] The transfer FPC is 20-30 mm long, which makes it convenient for testers to flip the module to be tested and reduce damage to the appearance of the display module.
[0061] The base 1 also includes a plurality of support frames 5, and the support frames 5 are used to place display modules.
[0062] The above-mentioned testing tooling can realize the testing process of the display module.
[0063] The embodiment of the present invention can simulate the functions of the entire machine through the above method, so that the display module to be tested enters the sleep gesture wake-up mode and performs a sleep wake-up test, and then detects whether the sleep wake-up function of the display module to be tested is normal based on the display picture effect of the display module to be tested after the test, thereby ensuring the quality and performance of the touch display module leaving the factory and improving the yield rate of the product.
[0064] Preferably, reference Figure 2The step S100 of lighting up and configuring the display module to be tested so that the TFT of the display module to be tested generates a touch scanning signal includes:
[0065] S110 , lighting up the display module to be tested, so that the display module to be tested displays a white picture.
[0066] Since the white screen consumes the most power among the conventional display screens (black, various grays, and white), testing its touch function under the white screen is the most representative and can improve the accuracy of the test.
[0067] Preferably, reference Figure 3 The step S110 of lighting up the display module to be tested so that the display module to be tested displays a white picture includes:
[0068] S111, power on the backlight and IOVCC / VSP / VSN of the display module to be tested;
[0069] Among them, IOVCC is the IO port voltage, usually 1.8V; VSP is the liquid crystal forward bias; VSN is the liquid crystal negative bias.
[0070] S112: downloading initialization code so that the display module to be tested displays a white screen.
[0071] Among them, the initialization code may include GOA timing (screen Source signal timing setting), GOA L&R (screen Source signal left and right timing setting), VGH VGL internal charge pump setting (IC internal VGH, VGL boost parameter setting), Vcom / Gamma Setting (screen vcom voltage, gamma voltage parameter setting), etc., so that the display module to be tested displays a white screen.
[0072] Preferably, reference Figure 2 The step S100 of lighting up and configuring the display module to be tested so that the TFT of the display module to be tested generates a touch scanning signal also includes:
[0073] S120, initializing the SPI interface of the TP touch control;
[0074] Wherein, the SPI interface includes MISO, MOSI, INT, RST, SCK and CSN interfaces.
[0075] S130, downloading the FW firmware and writing the FW firmware into the static random access memory of the touch IC of the display module to be tested;
[0076] The FW firmware is a firmware that simulates the touch function of the whole machine. The FW firmware can enable the display module to be tested to have touch-related functions, thereby entering the dormant gesture wake-up mode.
[0077] S140, synchronously writing the FW firmware into the control memory of the driver IC of the display module to be tested through the SPI protocol interface;
[0078] S150, starting the FW firmware to enable the TFT panel of the display module to be tested to generate a touch scanning signal.
[0079] Through the above steps, the display module to be tested can have touch function and sleep wake-up function.
[0080] Preferably, reference Figure 4 The step S200 of entering the sleep gesture wake-up mode and performing the sleep wake-up test includes:
[0081] S210, entering the sleep gesture wake-up mode;
[0082] S220: Obtain lpwg data in the sleep gesture wake-up mode.
[0083] Among them, the lpwg data includes the sensing capacitance (rawdata), etc. The purpose of obtaining the lpwg data in the sleep gesture wake-up mode is to determine whether the touch function of the display module to be tested is normal by testing whether the sensing capacitance (rawdata) is within the normal set specifications. If it is abnormal, the display module to be tested needs to be replaced or the above steps need to be repeated.
[0084] Preferably, the step S200 of entering the sleep gesture wake-up mode and performing the sleep wake-up test further includes:
[0085] S230, sleep and wait according to the set time;
[0086] The display module to be tested is in a normal display sequence. After entering lpwg, it will enter the lpwg sequence (sleep power saving sequence). The setting time is 1H-24H. In this interval, it is in the lpwg sequence. The sleep waiting time can be set according to the project specifications. The longer the time, the more stringent the test.
[0087] S240: Power on and wake up the display module to be tested.
[0088] Preferably, reference Figure 5 The step S300 of testing the display screen effect of the display module to be tested comprises:
[0089] S310, making the tested display module display a 128-level gray screen or a 64-level gray screen;
[0090] After the power-on wake-up operation is performed, the display module under test can display a 128-level gray screen or a 64-level gray screen. This is because: if the lpwg timing is set incorrectly, the screen display after wake-up will be abnormal, such as horizontal stripes, screen distortion, etc., especially the gray scale (64 gray, 127 gray, 128 gray) is easy to detect horizontal stripes.
[0091] S320, checking whether there are horizontal stripes or screen distortion in the 128-level grayscale image or the 64-level grayscale image;
[0092] S330: If horizontal stripes or a screen distortion appears, it is considered that the display screen is abnormal; otherwise, it is considered that the display screen is normal.
