Description

The application relates to an output voltage calibration method and equipment and a storage medium of the application named as 'short Bar' submitted to China patent office on the 27 th year of 2023, and the application number is 202310464588.5.
Technical Field
The application relates to the technical field of display screen dot screen detection, in particular to a method and equipment for calibrating output voltage of a short Bar and a storage medium.
Background
After the primary molding of the OLED CELL (OLED bare glass) panel is produced, the driving chip is not yet bound and needs to be detected by using a corresponding detection device. The short Bar (probe short circuit signal tester) is an analog signal generator capable of generating voltage waveform signals, and comprises an FPGA (Field-Programmable Gate Array, field programmable gate array), a digital-analog converter (DAC, digital to analog converter) group and a power amplifier which are connected in sequence, wherein the detection is specifically performed on an OLED CELL panel. During detection, a probe of shortingbar needs to be pressed on each branch contact of the OLED CELL panel, then a voltage waveform signal is output to each branch, and when the signal passes through a specific line, the organic materials (OLED) emit light to achieve the purpose of detection.
However, because of system noise, device aging, internal resistance of wires and the like existing in electronic components inside the shortening Bar, deviation between an actually output voltage value and a theoretical set value can occur, and if calibration is not performed, an output voltage error can be up to 500mV.
The related art discloses a voltage calibration method for a shortening Bar, which mainly calculates calibration parameters by a least square fitting straight line method. However, since the output voltage interval of the shortening Bar is large, the required accuracy is high, and the internal AD register value of the shortening Bar and the actual output voltage value are not in a simple linear relationship, a nonlinear voltage variation interval exists in a high voltage section (e.g., 38V-44V) and a low voltage section (e.g., -38V- (-44V)), and if the method is adopted, the accuracy requirement cannot be met in the nonlinear voltage output interval.

In the description of the present application, reference to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise.
The following describes the output voltage calibration method of the shortening Bar provided in the embodiment of the application with reference to fig. 1 and fig. 2, and the shortening Bar can be used to light the OLED CELL panel. The method may be applied to a computer device as shown in fig. 1, i.e. the method may be performed by individual hardware parts of the computer device in combination with corresponding software programs. In fig. 1, a computer device, an oscilloscope, and a shortening Bar as a voltage calibration object are connected to each other. The method comprises the following steps:
s201, transmitting a voltage control parameter to the shortening Bar, wherein the voltage control parameter is used for indicating an output end of the shortening Bar to respectively output a plurality of different expected voltage values in a plurality of continuous first time periods.
The computer device may be, for example, a PC (Personal Computer) machine, and in an embodiment, the computer device may send the voltage control parameter generated by it to the shortening Bar so that the shortening Bar outputs the desired voltage value from its output based on the voltage control parameter. Illustratively, when the digital-to-analog converter DAC is configured in the shortening Bar, and the shortening Bar receives and operates the voltage control parameter, a corresponding internal voltage is generated inside the shortening Bar by the digital-to-analog converter DAC, and the internal voltage is transmitted to the output end of the shortening Bar through the internal circuit of the shortening Bar, so that an external voltage is generated at the output end. However, in step S201 of the present embodiment, the external voltage generated at the output terminal is not used to directly light the OLED CELL panel, but is used to compare with the expected voltage value and calibrate the shortening Bar based on the comparison result, so the waveform (variation rule) of the external voltage does not need to completely correspond to the required waveform of the OLED CELL panel. Therefore, in order for the shortening Bar to rapidly and regularly output a plurality of different voltage values in a short time so as to improve the calibration efficiency, the aforementioned voltage control parameters may be configured to: such that the aforementioned plurality of expected voltage values sequentially increment (or decrement) in equal amplitude in time series, and the amplitude (i.e., the amplitude in the aforementioned "equal amplitude") is the minimum step voltage of the shortening Bar. It will be appreciated that the aforementioned minimum step voltage is related to the step accuracy of the digital-to-analog converter DAC within the shortening Bar.
The first period of time may be a minimum stepping time of the shortening Ba.
And S102, when the shortening Bar outputs a voltage signal (which is a changed waveform signal) from an output end thereof in response to the voltage control parameter, the oscilloscope is controlled to acquire the actual measurement voltage value of the shortening Bar output end once every second time period, wherein the (duration of the) first time period is N times of the (duration of the) second time period, and N is not less than 5.
Since the actual voltage value output by the shortening Bar may deviate from the expected voltage value due to the influence of factors such as the internal resistance of the shortening Bar, the voltage value actually output by the shortening Bar may be measured by the voltage measuring device so as to be compared with the corresponding expected voltage value in step S203 described below, and whether the deviation is within an acceptable range is determined based on the result of the comparison.
Compared to the conventional voltage testing apparatus, the inventors noted that an oscilloscope capable of collecting the voltage value (level value) in the voltage signal at a high frequency can be skillfully applied in the present scheme. Even a common oscilloscope can collect a voltage value every 10 μs, and the duration of the same level value in a voltage signal (required by the OLED CELL panel) provided by the shortening Bar to the OLED CELL panel is typically several hundred μs, so that the oscilloscope can collect a plurality of measured voltage values, for example, more than 5 measured voltage values, in each first period.
In one example (hereinafter referred to as example a), the voltage control parameter provided by the computer device is used to instruct the output terminal of the shortening Bar to sequentially and progressively output 8001 expected voltage values different from each other in consecutive 8001 200 μs time periods, the voltage values being 40.000V, 39.990V, 39.980V, 39.970V, …, -39.990V, -40.000V, respectively, and the oscilloscope collects the actual measured voltage value of the output terminal of the shortening Bar every 10 μs. That is, in this example a, the first period of time (the duration of time) is 200 μs, the second period of time (the duration of time) is 10 μs, n=20, the oscilloscope needs only 16 seconds to complete the voltage value acquisition of all the signal bands, and the voltage value of each signal band (one expected voltage value corresponds to one signal band) can be acquired 20 times successively.
S203, comparing each expected voltage value in the expected voltage values with a plurality of measured voltage values corresponding to the expected voltage value.
S204, if the comparison result does not meet the set condition, after the voltage control parameter is adjusted, repeating the steps until the comparison result meets the set condition.
It is understood that the set condition is a condition that the difference between the measured voltage value and the expected voltage value is within an acceptable range, and if the difference is not within the acceptable range, the set condition is not satisfied, then the computer device may adjust the voltage control parameter, and send the adjusted voltage control parameter to the shortening Bar, and so on until the set condition is satisfied.
For each of a plurality of expected voltage values (such as 8001 in the foregoing example a), the expected voltage value is compared with a plurality of measured voltage values to which it corresponds. For example, in the foregoing example a, for an expected voltage value of 20.000V, corresponding to 20 actually measured voltage values collected sequentially in a time period from 400000 μs to 400200 μs, the expected voltage value of 20.000V is subjected to one-to-one difference comparison with five, 10 or all 20 of the foregoing 20 actually measured voltage values, and if there is an excessive difference, for example, exceeding ±30mv, it is indicated that the voltage control parameter currently configured for the shortening Bar does not reach the standard at 20.000V, and at least the parameter portion of the voltage control parameter at 20.000V needs to be readjusted.
In this embodiment, each expected voltage value is compared with a plurality of actually measured voltage values corresponding to the expected voltage value, and if one actually measured voltage value does not meet the requirement, a control parameter portion corresponding to the expected voltage value is adjusted, so that the shortening Bar can accurately and stably output various required voltage values.
In the foregoing example a, although the voltage value of each signal band is collected 20 times in succession, it is not necessary to compare each expected voltage value with all 20 measured voltage values corresponding thereto, because: under the condition that the same signal wave band (one (continuous) signal wave band corresponds to an expected voltage value) of the output voltage signal, the voltage control parameter enables the AD register value in the short Bar to be a fixed value, so that the voltage value generated by a voltage generating unit (such as a DAC and the like) in the short Bar is fixed, and therefore, in ideal cases, 20 measured voltage values acquired successively are identical. In case each expected voltage value is compared with all 20 measured voltage values it corresponds to, the data processing burden of the computer device will be multiplied.
The inventor notes that when the output voltage of the shortening Bar is changed from one band to another adjacent band, or when the output voltage of the shortening Bar is changed from one expected voltage value to another adjacent expected voltage value, for example, when the output voltage is changed from 30.000V to 30.010V, the actual output voltage jumps, for example, the actual output voltage jumps to 30.012V and returns to 30.010V V, mainly because of the influence of inductive reactance and capacitive reactance in the internal circuit of the shortening Bar. The jump voltage typically occurs within 20 mus of the switching time point of the adjacent two expected voltage values. The momentary high jump voltage, if transmitted to the OLED CELL panel, may also cause the OLED CELL panel to burn out.
Therefore, in order to compromise between the small data processing burden and the measurement of the jump voltage, in some embodiments, step S203 may be specifically set as follows:
each of the plurality of expected voltage values is compared with at least four measured voltage values corresponding to the expected voltage value. At least two of the at least four measured voltage values are acquired within the first 20 mu s of the corresponding first time period; at least two of the at least four measured voltage values are acquired within the last 20 mus of the corresponding first period.
It will be appreciated that at least two measured voltage values collected in the first 20 μs and at least two second measured voltage values collected in the second 20 μs may generally reflect jump voltage information of the short Bar when switching the output voltage. The more measured voltage values are collected within the first 20 mus and within the last 20 mus, the more accurate the jump voltage information is reflected.
In step S204, the setting conditions thereof may be: the difference between each of the at least four measured voltage values and the expected voltage value does not exceed a set threshold range. The set threshold range may be dependent on the requirements of the OLED CELL panel, for example, the set threshold range may be configured to-30 mV to +30mV.
In other embodiments, in order to fully ensure the accuracy of the voltage calibration, the step S203 may also be: each of the plurality of expected voltage values is compared with all measured voltage values corresponding to the expected voltage value. For example, in the foregoing example a, each expected voltage value may also be compared with all 20 measured voltage values corresponding to the expected voltage value. In combination with the above description, in order to reduce the omission of the jump voltage, for each expected voltage value, at least two measured voltage values are acquired within the first 20 μs of the first period corresponding to the expected voltage value, and at least two measured voltage values are acquired within the first 20 μs of the first period corresponding to the expected voltage value, among all measured voltage values corresponding to the expected voltage value. This means that the duration of the second period of time does not exceed 10 mus. In such embodiments, the set conditions may be: the difference between each expected voltage value and each of all measured voltage values corresponding thereto (e.g., each of the 20 measured voltage values in example a) does not exceed the set threshold range.
The "if the comparison result does not meet the set condition, the voltage control parameter is adjusted" described in step S204 may specifically include:
if the comparison result corresponding to the first expected voltage value meets the set condition, the comparison result corresponding to the second expected voltage value does not meet the set condition, removing a parameter part corresponding to the first expected voltage value in the voltage control parameter, and changing the parameter part corresponding to the second expected voltage value in the voltage control parameter to obtain the adjusted voltage control parameter; the first expected voltage value is any one of a plurality of expected voltage values, and the second expected voltage value is any one of a plurality of expected voltage values.
To facilitate an understanding of the solution described in the previous paragraph, the foregoing example a is taken as an example. In example a, when steps S201-S203 are performed for the first time, 8001 expected voltage values are compared with a plurality of measured voltage values corresponding to the 8001 expected voltage values, respectively, and the comparison result may show that: the measured voltage values corresponding to 1000 expected voltage values meet the requirements, and the measured voltage values corresponding to the rest 7001 expected voltage values do not meet the requirements. If the actual output voltages corresponding to the 1000 expected voltage values are still measured and compared again when the steps S201 to S203 are performed for the second time, the data processing capacity of the computer device is meaninglessly increased, so that the voltage calibration time for the shortening Bar output terminal is excessively prolonged. Therefore, when steps S201 to S203 are performed for the second time, the parameter portion corresponding to the foregoing 1000 expected voltage values in the initial voltage control parameter may be removed, and the parameter portion corresponding to the foregoing 7001 expected voltage values in the voltage control parameter may be changed, where the output end of the tuning Bar outputs a plurality of different expected voltage values only in 7001 consecutive first time periods, and then the actual output voltages corresponding to these 7001 expected voltage values are measured and compared, and the voltage control parameter in the computer device is adjusted again based on the comparison result, and so on, until the actual measured voltages corresponding to all 8001 expected voltage values reach the requirement, so as to obtain the ideal voltage control parameter adapted to each expected voltage value.
The voltage control parameters are used to control the shortening Bar to set rules to output the voltage signal, which should be compatible with the performance parameters of the oscilloscope and the shortening Bar. In this regard, in some embodiments, before transmitting the voltage control parameter to the shortening Bar, i.e., before proceeding to step S201 for the first time, the method may further include:
acquiring parameter information of an oscilloscope and a shortening Bar;
based on this parameter information, an (initial) voltage control parameter is determined.
Referring back to fig. 1, the embodiment of the present application further provides a computer device for calibrating the output voltage of the shortening Bar, including: a memory, a processor, program instructions stored in the memory and executable by the processor; the program instructions, when executed by a processor, cause the computer device to perform the method described above.
In addition, the embodiment of the application also provides a computer readable storage medium, which stores program instructions, when the program instructions run on a computer device, cause the computer device to execute the method.
