[ detailed description ] embodiments
The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive step are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of an electrostatic testing method applied to a driving control device according to an embodiment of the present application, where the specific flow of the electrostatic testing method may be as follows:
s101: and supplying power to the display equipment to be tested and sending a preset video signal.
Specifically, please refer to fig. 2, fig. 2 is a schematic diagram of a connection structure of a display Device to be tested and a driving control Device provided in this embodiment of the present application, as shown in the figure, the driving control Device 10 is connected to the display Device 20 to be tested through an interface 30, so as to supply power to the display Device 20 to be tested and send a preset video signal, the driving control Device 10 may be a GOA driver board provided with a Programmable chip 11, and the Programmable chip 11 may be an FPGA (Field Programmable Gate Array) chip or a CPLD (Complex Programmable Logic Device) chip. The display device 20 includes a display panel 21 and a control board 25, the control board 25 is connected to a printed circuit board 23 through a flexible circuit board 24, and the printed circuit board 23 is connected to the display panel 21 through a source flip-chip 22, so as to electrically connect the control board 25 and the display panel 21. The display panel 21 is integrated with a GOA circuit, the control board 25 is provided with a screen drive board (TCON)251, the driving control device 10 sends a preset video signal to the screen drive board 251, the screen drive board 251 initializes, and then supplies the preset video signal to the display panel 21 to drive the display panel 21 to display a picture according to the preset video signal.
S102: and detecting the starting time of initialization of the display equipment to be tested in the picture display process and estimating the consumed time.
Specifically, when the drive control device is connected with the display device to be tested, power is supplied to the display device to be tested, at this time, the display device to be tested starts initialization, and the initialization start time is obtained and used for determining the test start time of the static test device in the subsequent steps.
In this embodiment, the estimated elapsed time may be measured by an oscilloscope in advance by a person skilled in the art, and then preset in the drive control device in advance in the form of a parameter.
S103: and determining the discharge starting time and the discharge frequency according to the starting time and the estimated consumption time.
In this embodiment, step S103 may specifically include the following sub-steps:
determining the discharge starting time according to the starting time and the preset delay time;
and determining the discharge frequency according to the estimated consumption time and the preset single discharge time.
Specifically, the discharge start time may be determined by performing corresponding time delay on the start time obtained in the previous step, for example, if the preset time delay duration is 1s, discharging is performed on the start time delay 1s, that is, the static test is performed 1s after the initialization starts.
Further, the generation of static electricity has great contingency and randomness, the generation time of the static electricity is not long-term and uninterrupted, and the practicability is not satisfied if the static electricity testing equipment discharges continuously, so the testing practicability can be ensured by controlling the discharging frequency of the static electricity testing equipment. Specifically, the discharge frequency may be preset in the drive control device in advance in the form of a parameter, or the discharge frequency may be determined according to the estimated consumed time length and the preset single discharge time length.
S104: and controlling the static test equipment to carry out static test on the display equipment to be tested in the initialization process according to the discharge starting time and the discharge frequency.

determining a plurality of discharge times according to the discharge start time and the discharge frequency;
generating a discharge command every time a discharge time is reached;
and sending a discharge command to the static electricity testing equipment.

And generating a discharge instruction when the discharge time is reached, and sending the discharge instruction to the static test equipment to instruct the static test equipment to discharge the display equipment to be tested so as to carry out static test on the display equipment to be tested.
Specifically, the electrostatic testing device may be an ESD tester, and a conventional ESD tester is generally an electrostatic discharge simulator integrating control of a discharge gun head and a touch screen, however, in this embodiment, the electrostatic testing device may be directly the discharge gun head, and the control of the discharge gun head is realized through the electrical connection between the discharge gun head and the drive control device, and the touch screen does not need to be manually operated, so that full automation of the test is realized.
In other embodiments, the driving control device may directly send the discharge start time and the discharge frequency to the electrostatic test device, and the electrostatic test device may directly perform the discharge operation according to the discharge start time and the discharge frequency without generating a discharge instruction and without always interacting with the electrostatic test device.
In some embodiments, the static electricity testing method may further include the steps of:
determining an ending time according to the starting time and the estimated consumed time;
and determining the discharge end time according to the end time.
Specifically, the purpose of the static electricity test method is to test whether static electricity will damage the display device under test at the time of initialization, and therefore, the static electricity test should be ended against the end of initialization.
Further, the discharge end time may be just the end time, or may be a preset time period before the end time, and the preset time period may be 1 s.
Referring to fig. 3, fig. 3 is another schematic flow chart of an electrostatic testing method according to an embodiment of the present disclosure, in other embodiments, the electrostatic testing method may further include the following steps:

In some embodiments, the driving control device includes a camera, and step S105 may specifically include:
in the static test process, shooting a display picture of the display equipment to be tested through a camera to obtain a shot image;
judging whether the shot image is matched with a preset image or not;
if so, determining that the picture display state of the display equipment to be tested is normal;
if not, determining that the display state of the display equipment to be tested is abnormal.
Specifically, before the static electricity test is started, a display frame of the preset video signal on the display device under the normal condition may be captured by the camera, and the captured image is stored as the preset image, so as to facilitate the subsequent determination step, for example, please refer to fig. 4, where fig. 4 is a display diagram of the preset video signal provided in the embodiment of the present application under the normal display condition, and the display frame of the preset video signal on the display device may be a transition frame of red (R)41, green (G)42, blue (B)43, and white (W) 44.
In this embodiment, the step of "determining whether the captured image matches the preset image" may specifically include:
acquiring a first pixel value of each pixel point in the shot image and a second pixel value of each pixel point in a preset image;
determining the number of pixel points of which the first pixel values and the corresponding second pixel values are not matched in the shot image;
when the number is larger than the preset number, judging that the shot image is not matched with the preset image;
and when the number is less than or equal to the preset number, judging that the shot image is matched with the preset image.
Specifically, during testing, the electrostatic testing device directly discharges the display panel of the display device to be tested, and therefore some pixel points of the display panel are interfered, and during statistics, data of the part, generally data of the edge of the display panel, needs to be removed.
Further, the first pixel value and the corresponding second pixel value of the shot image can be matched by calculating the difference value of the two, and if the difference value of the two is greater than 100, the two are not matched.
The preset number is obtained by dividing the total number of all the pixels by the number of the driving chips and multiplying the number by ten percent, wherein the number of the pixels receiving the interference is subtracted from the total number of the pixels.
S106: and when the display state of the picture is abnormal, controlling the static test equipment to stop static test and stopping supplying power to the display equipment to be tested.
In this embodiment, step S106 may specifically include:
generating an interrupt instruction;
and sending an interrupt instruction to the static test equipment, wherein the static test equipment is used for instructing the static test equipment to stop discharging to the display equipment to be tested so as to stop the static test.
Specifically, when the screen display state is abnormal, representing that static electricity damages the initialization process, that is, the initialization code and the flash memory data are changed, the initialization process should be stopped immediately at this time, so as to prevent the code and the data from being changed completely, and increasing difficulty in maintenance and recovery of the subsequent display device to be tested.
Different from the prior art, the static test method provided by the application is applied to the drive control equipment, the display equipment to be tested is powered on and sends a preset video signal, so that the display equipment to be tested displays pictures according to the preset video signal, then the starting time of initialization of the display equipment to be tested in the picture display process is detected and the consumed time duration is estimated, then the discharging starting time and the discharging frequency are determined according to the starting time and the estimated consumed time duration, then the static test equipment is controlled to carry out the static test on the display equipment to be tested in the initialization process according to the discharging starting time and the discharging frequency, so that the static test is carried out in the initialization of the display device, the damage of static discharge to the display device in the initialization process can be effectively detected, the coverage rate of the static test is further improved, and the static test process is more comprehensive and complete, the risk that the display device on the market cannot be normally started is returned in advance.
