Background
With the development of electronic technology, the automobile industry gradually appears many electronic accessories, and the vehicle-mounted screen is applied to almost every automobile as an automobile accessory.
The vehicle-mounted screen usually has a flicker situation due to the design principle, and the current processing mode of the defect is to detect the optimal common voltage (the voltage of the common electrode which enables the flicker value to be minimum) and burn the optimal common voltage into the chip to promote the static electricity discharge during aging, then put the screen under a certain condition to age for a period of time (such as 2 hours), so that the static electricity in the screen is discharged, then detect the current optimal common voltage again, and burn the optimal common voltage into the chip.
For a production line, due to the limitation of production takt, setting one more production site per production site may cause a large amount of capacity waste, and in fact, the static electricity of a screen is a continuous releasing process, an aging link is only a stage of fast static electricity releasing speed, if production time is not considered, aging time is better as long as possible, but the best scheme in the industry at present is to burn twice the optimal common voltage because the detected optimal common voltage is the most stable real common voltage of the screen only after the static electricity is completely released, the optimal common voltage detected before and after aging is only the optimal value at the time and is only continuously close to the optimal common voltage after the static electricity is completely released, so that the transition is performed in the industry by a twice burning mode at present to provide the common voltage with the corresponding regulation, and the optimal voltage is the detectable optimal solution at the time.

The term "and/or" and/or "includes all combinations of any one or more of the associated listed items.
The static electricity of the screen is a process of continuously discharging, and therefore, the optimum common voltage is a process of continuously changing and a change width is smaller and smaller, and if the optimum common voltage of the screen after aging for a long time can be obtained, it is not necessary to use twice the optimum common voltage for transition which is currently used in the industry.
Therefore, the optimal public voltage after a long time can be directly burned before aging, and secondary burning is not needed after aging, so that the production link is shortened, and the production efficiency is improved.
The reason why the optimal common voltage is burned into the chip is that the screen uses alternating current, parasitic capacitance is formed in the screen production process, brightness is different before and after voltage is turned over, and the influence of the parasitic capacitance can be counteracted by applying certain voltage.
The parasitic capacitance is actually related to a coating in the screen, such as ITO, a pixel layer, and the like, so that the change condition of the optimal common voltage can be analyzed in combination with the factors, and in addition, the optimal common voltage burned for the first time can reflect the condition of the screen to a certain extent, and therefore, the change condition of the optimal common voltage can also be analyzed.
Fig. 1 is a schematic structural diagram of an automobile accessory production system based on parameter configuration according to an embodiment of the present disclosure, where the system may include:
the platform 101 is used for acquiring the growth thickness of each coating collected by the production detection station 102 of the sample vehicle-mounted screen, detecting the current optimal common voltage before aging, and lighting the sample vehicle-mounted screen for aging at preset temperature, humidity and time by using the current optimal common voltage before aging as the voltage of a common electrode;
detecting and reading the aged current optimal common voltage by the production detection station, burning the aged current optimal common voltage into a chip of the sample vehicle-mounted screen, uploading the current optimal common voltage to the platform, and recording a lighting time recording program into the chip;
the production line may have a production management system for managing each station in the production line, including: a production test site.
The production detection station 102 can collect the growth thickness of the coating, and currently, the production detection station is only used for judging whether the thickness meets the design requirement, but not used more, which is actually a waste of data, so that the production detection station can be used.
Then, the platform may obtain the growth thickness of each coating collected by the production detection station 102 through the production management system.
The prior art is disclosed for the type of coating and is not specifically described here.
The production detection station before aging can detect the current optimal common voltage before aging and can also burn the current optimal common voltage into the chip.
And then, an aging station, and the vehicle-mounted screen is lightened for aging at preset temperature, humidity and time.
And for the sample vehicle-mounted screen, continuously detecting the aged current optimal common voltage again after aging according to the current production mode in the industry, burning, uploading to the platform as one of sample information for recording, and simultaneously recording a lighting time recording program into the chip so as to record the accumulated lighting time of the screen later.
And the maintenance terminal 103 is used for detecting the current optimal public voltage and the recorded accumulated lighting time of each sample vehicle-mounted screen during vehicle maintenance and uploading the current optimal public voltage and the recorded accumulated lighting time to the platform.
This is the process for the sample on-board screen.
After the platform collects the sample information, the next step of processing can be carried out.
The platform 101 performs fitting and calculates the limit value of the common voltage by using the current optimal common voltage and the corresponding lighting time before aging, the current optimal common voltage and the corresponding lighting time after aging, the optimal common voltage collected during maintenance, and the accumulated lighting time.
In order to realize the individualized parameter configuration of each vehicle-mounted screen in the subsequent production, the common voltage limit value of each vehicle-mounted screen to be configured needs to be obtained, obviously, the vehicle-mounted screen to be configured does not leave a factory or even is not aged, and therefore, the processing mode of the sample vehicle-mounted screen cannot be completely carried to the vehicle-mounted screen to be configured.
However, the public voltage limit value of the vehicle-mounted screen to be matched with the parameters can be predicted in a prediction mode, before aging, the public voltage limit value cannot be recorded into a chip as long as the current optimal public voltage (before aging) is detected, the current optimal public voltage and the coating thickness are combined, the public voltage limit value is predicted and used as the burning voltage, one-time burning is achieved, and two transitions are not needed.
In this regard, a model for predicting the extreme values needs to be trained.
This is why we have to collect the current optimum common voltage and the corresponding lighting time for maintenance, since by fitting, the limit values can be obtained, so that there are both the goal we need and the factors reflecting this goal in the platform, so that the voltage prediction model can be trained in a supervised learning manner.
Therefore, the platform 101 is further configured to train the voltage prediction model by using the batch samples, with the vehicle-mounted screen of each sample as a single sample, setting a label according to the corresponding public voltage limit value, and with the corresponding growth thickness of each coating and the current optimal public voltage before aging as sample information.
After the voltage prediction model is obtained, the limit value can be predicted under the condition that only the growth thickness of the coating and the current optimal common voltage before aging are known.
And the parameter distribution module 104 is used for deploying the voltage prediction model, acquiring the growth thickness of each coating collected by the vehicle-mounted screen to be distributed, detecting the current optimal public voltage before the vehicle-mounted screen to be distributed is aged, inputting the current optimal public voltage into the voltage prediction model, predicting and outputting the public voltage limit value of the vehicle-mounted screen to be distributed, burning the public voltage limit value into a chip of the vehicle-mounted screen to be distributed and aging the chip, and burning the public voltage after the production line is aged.
The limit value may be a value close to the obtained function image, and of course, the value of the common voltage at the lifetime in the specification of the on-vehicle screen may be substituted in consideration of the fact that the lifetime of the screen is limited.
Therefore, in the embodiment of the present specification, the calculating the common voltage limit value may include:
and determining the specification service life of the vehicle-mounted screen, and calculating the common voltage reaching the specification service life by using the fitted function as the limit value of the common voltage.
Fig. 2 is a schematic diagram of an automobile accessory production system based on parameter configuration according to an embodiment of the present disclosure, and fig. 2 shows a function image of an optimal common voltage obtained by fitting, and an image of the optimal common voltage detected before and after aging, where t1 is a time before aging, t2 is a time after aging, t is a variable, a flicker curve is a curve obtained by detecting a plurality of times before aging, and when an applied common voltage value is Vt1, flicker is minimum, so Vt1 is the optimal common voltage before aging, likewise, vt2 is the optimal common voltage after aging, and at the time of fitting, one or more time points are collected at the time of maintenance and are not shown in detail in fig. 2, and after obtaining the function Vt, a common voltage limit value can be calculated as Vfinal.
In this embodiment, the detecting the current optimal common voltage before aging includes:
and selecting expected voltage by using a dichotomy, applying the expected voltage to the vehicle-mounted screen, detecting a flicker index value, and when the flicker index value meets a preset condition, taking the corresponding expected voltage as the current optimal public voltage.
The dichotomy is a method for detecting the middle value, after the flicker corresponding to the middle voltage is detected, the flicker is compared with the flicker values at two ends, the middle value is used as one end point, the end point with smaller difference is selected as the other end point, the end point with smaller difference is abandoned, and the detection is carried out by continuously taking the two middle values next time.
In an embodiment of the present specification, the acquiring of the growth thickness of each coating collected by the production detection station of the sample on-board screen includes:
and after the growth thickness of each coating collected by the production detection station is detected, the platform searches the growth thickness of each coating corresponding to the sample vehicle-mounted screen through a tracing system.
Currently, in the case of growing coatings, the thickness specification of each coating is individually controlled, that is, once the thickness of a certain coating exceeds a certain range, the coating is determined as a waste product, however, in practice, the effect between some coatings is complementary, that is, the a and b coatings can cause the flicker to become serious, but because the effect is opposite, the b coating can recover the excessive effect of the a diagram, like 3+ (-2) =1, which is smaller than the absolute value of 3 and smaller than the absolute value of (-2).
Therefore, in the embodiments of the present specification, the production system may further have:
and the coating growth station is deployed with the voltage prediction model, determines the thickness of a grown first coating when the coating of the vehicle-mounted screen is produced, selects a plurality of thicknesses to be compared on two sides of the thickness specification of an overgrown second coating if the thickness of the first coating exceeds the specification, combines the thickness of the first coating and a preset optimal common voltage to input the thicknesses into the voltage prediction model to obtain a plurality of common voltage limit values, selects the minimum common voltage limit value and the corresponding overgrown coating thickness, adjusts the thickness specification of the overgrown coating, and performs coating growth according to the adjusted rule.
Thus, by presetting the optimal common voltage, the thickness of the grown first coating and the selected thickness to be compared can be combined and input into the voltage prediction model, a common voltage limit value is predicted, for each selected thickness to be compared, a common voltage limit value can be obtained, and due to the control of other variables, if the predicted common voltage limit value can meet the condition, the corresponding thickness can recover the negative influence caused by the unqualified thickness of the first coating.
In the embodiment of the present specification, said selecting a plurality of thicknesses to be compared on both sides of the thickness specification of the second coating layer not grown includes:
dividing the plurality of coatings into two groups with opposite parasitic capacitance influence factors, determining the group of the first coating, and selecting an ungrown coating from the other group as a second coating;
and selecting a plurality of thicknesses to be compared on two sides of the thickness specification of the second coating respectively.

determining the influence attribute of the coating on the parasitic capacitance according to the information of the side where the coating is located, the communication state of the coating and the electrode and the material of the coating;
and dividing the coatings with the same influence property into the same group to obtain two groups of coatings.
The side where the coating is present means that the screen has a liquid crystal layer, and the inside of the glass on both sides of the liquid crystal layer has different coatings.
The state of communication between the coating and the electrodes means that some of the coating is insulated from the electrodes and some of the coating is in electrical communication with the electrodes.
The specific grouping method is described in the prior art and is not specifically described herein.
