Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
The pulse signal is a discrete signal with various shapes, and compared with a common analog signal (such as a sine wave), the waveforms are discontinuous on the time axis (the waveforms have obvious intervals) but have certain periodicity. The Pulse signal may be used to represent information, or may be used as a carrier, such as Pulse Code Modulation (PCM) and Pulse Width Modulation (PWM) in Pulse Modulation, and may also be used as a clock signal for various digital circuits and high-performance chips. The modulation method of the pulse signal is not limited in the embodiment of the present application, and it should be understood that the pulse signal in the embodiment of the present application is used to provide a voltage for the device to be pressurized/reduced, so that the device to be pressurized/reduced is pressurized/reduced to a target voltage.
Fig. 1 is an exemplary diagram of a pulse signal. As shown in fig. 1, the ideal waveform of the pulse signal is shown by a dotted line by taking a square wave as an example, but since the pulse signal shows transient characteristics in the rising process, it takes a certain time to reach the target voltage, and if the device to be pressurized/depressurized is driven at a high frequency or the rising time of the pulse signal is required to be short, the voltage cannot be sufficiently boosted, so that the effective voltage does not coincide with the target voltage, that is, the waveform of the voltage signal in the solid line in fig. 1 does not coincide with the dotted line.
In order to solve the above problem, the present application provides a signal compensation method. Fig. 2 is a first scenario diagram illustrating a signal compensation method applied in the present application. As shown in fig. 2, the applicable scenarios of the signal compensation method provided in the present application may include: control equipment, a pulse signal generator, equipment to be pressurized/depressurized and calibration equipment.
The control equipment, the pulse signal generator and the equipment to be pressurized/depressurized are connected in sequence, and the calibration equipment is connected with the control equipment, the pulse signal generator and the equipment to be pressurized/depressurized respectively.
The control device in the application is used for outputting the set voltage and the set duty ratio. Duty cycle refers to the proportion of the time that power is applied to the total time in a pulse cycle. In one possible implementation, the control device may be an electronic device with a display interface, and the control device is configured to receive a set voltage and a set duty ratio input by a user.

Optionally, the control device may be a terminal device with a display interface, such as a mobile phone and a computer.
The pulse signal generator is used for generating a pulse signal according to the set voltage and the set duty ratio output by the control equipment. The pulse signal generator may output the pulse signal to the device to be pressurized/depressurized after generating the pulse signal. The principle of generating the pulse signal by the pulse signal generator is the same as that in the prior art, and is not described herein again.

Alternatively, the device to be pressurized/depressurized may be a liquid crystal display panel.
The calibration equipment in the application is used for measuring the actual voltage output by the to-be-pressurized/voltage-reducing equipment and the set voltage sent by the control equipment, acquiring the voltage difference value between the actual voltage and the set voltage and feeding back the voltage difference value to the pulse signal generator. And then the pulse signal generator compensates the pulse signal according to the voltage difference value.
It should be understood that, in the signal compensation method provided by the present application, the pulse signal generator compensates the pulse signal generated by the pulse signal generator according to the voltage difference between the actual voltage of the device to be pressurized/reduced and the set voltage measured by the calibration device, so that the voltage of the device to be pressurized/reduced reaches the target voltage.
The signal compensation method provided by the present application is described below with reference to specific embodiments. Fig. 3 is an interaction flow diagram of an embodiment of a signal compensation method provided in the present application. As shown in fig. 3, the signal compensation method provided by the present embodiment is explained in terms of interaction between the pulse signal generator and the calibration device in the present embodiment. The signal compensation method provided by the embodiment may include:
s301, the calibration device measures the current actual voltage output by the device to be pressurized/depressurized.
The calibration device in this embodiment can measure the current actual voltage output by the device to be pressurized/depressurized.
It should be understood that the current actual voltage output by the device to be pressurized/depressurized is output after the pulse signal generator outputs the pulse signal to the device to be pressurized/depressurized. In this case, the pulse signal generator outputs the pulse signal after the control device outputs the current set voltage and the current duty ratio to the pulse signal generator.
Optionally, a user may input the current setting voltage and the current duty ratio in the control device, so that the pulse signal generator outputs a corresponding pulse signal according to the current setting voltage and the current duty ratio.
S302, the calibration device calculates the current voltage difference value between the current actual voltage and the current set voltage of the device to be pressurized/depressurized.
In this embodiment, in a possible implementation manner, after the control device outputs the current setting voltage and the current duty ratio to the pulse signal generator, the control device may further send the current setting voltage to the calibration device. In one possible implementation, the control device may transmit the current setting voltage to the calibration device while outputting the current setting voltage and the current duty ratio to the pulse signal generator. In one possible implementation, the pulse signal generator may send the current set voltage to the calibration device after receiving the current set voltage and the current duty cycle from the control device. The manner how the calibration device receives the current set voltage of the device to be pressurized/depressurized is not limited in this embodiment.
After the calibration device measures the current actual voltage output by the device to be pressurized/depressurized, the current voltage difference between the current actual voltage and the current set voltage of the device to be pressurized/depressurized can be calculated.
And S303, the calibration equipment feeds the current voltage difference value back to the pulse signal generator.
Correspondingly, the pulse signal generator receives the current voltage difference value sent by the calibration equipment.
In this embodiment, after the calibration device calculates and obtains the current voltage difference between the current actual voltage and the current set voltage output by the to-be-pressurized/depressurized device, the calibration device may feed back the current voltage difference to the pulse signal generator, that is, send the current voltage difference to the pulse signal generator.
S304, the pulse signal generator compensates the pulse signal output to the equipment to be pressurized/depressurized according to the current voltage difference value, the current duty ratio, the current set voltage and the corresponding relation between the voltage difference value and the set voltage and duty ratio.
In this embodiment, corresponding to the above, in a possible implementation manner, after the control device outputs the current setting voltage and the current duty ratio to the pulse signal generator, the control device may further send the current setting voltage to the calibration device, and at this time, the control device may also send the current duty ratio to the calibration device. In one possible implementation, the control device may simultaneously transmit the current setting voltage and the current duty ratio to the calibration device while outputting the current setting voltage and the current duty ratio to the pulse signal generator. In one possible implementation, the pulse signal generator may send the current setting voltage and the current duty ratio to the calibration device after receiving the current setting voltage and the current duty ratio from the control device. In this embodiment, there is no limitation on how the calibration device receives the current set voltage and the current duty ratio of the device to be pressurized/depressurized.
The pulse signal generator may store a correspondence between the voltage difference and the set voltage and the duty ratio. The corresponding relationship may be in a table form, a function form, or the like, so as to represent the one-to-one correspondence between the voltage difference and the set voltage and the duty ratio.
Optionally, the corresponding relationship may be obtained by the pulse signal generator according to the stored test voltage difference value, the test set voltage, and the duty ratio, or may be sent to the pulse signal generator after being obtained by the calibration device according to the test voltage difference value, the test set voltage, and the duty ratio. It should be understood that the test voltage difference and the test set voltage, test duty cycle, are obtained during the testing of the device to be pressurized/depressurized according to the architecture shown in fig. 2 in the present application.
After the pulse signal generator receives the current voltage difference value sent by the calibration equipment, the pulse signal generator can compensate the pulse signal output to the equipment to be pressurized/depressurized according to the current voltage difference value, the current duty ratio, the current set voltage and the corresponding relation between the voltage difference value and the set voltage and duty ratio.
Optionally, in this embodiment, the pulse signal generator may compensate the pulse signal output to the device to be pressurized/depressurized by: the pulse signal generator determines the target set voltage according to the current voltage difference value, the current duty ratio, the current set voltage and the corresponding relation between the voltage difference value and the set voltage and the duty ratio. It should be understood that, in the corresponding relationship, the voltage difference corresponding to the target setting voltage may be a target voltage difference, and the difference between the target setting voltage and the target voltage difference is the current setting voltage.
Correspondingly, the pulse signal generator can compensate the pulse signal output to the equipment to be pressurized/depressurized according to the target set voltage. Specifically, the pulse signal generator outputs a pulse signal corresponding to the target set voltage, so that the actual voltage of the device to be pressurized/depressurized is the current set voltage, and the device to be pressurized/depressurized actually outputs the current set voltage.
The signal compensation method provided by the embodiment comprises the following steps: receiving a current voltage difference value sent by calibration equipment, wherein the current voltage difference value is a difference value between a current actual voltage output by equipment to be pressurized/reduced voltage and a current set voltage measured by the calibration equipment; and compensating the pulse signal output to the equipment to be pressurized/depressurized according to the current voltage difference value, the current duty ratio, the current set voltage and the corresponding relation between the voltage difference value and the set voltage and duty ratio. According to the signal compensation method, the pulse signal generator can compensate the pulse signal generated by the pulse signal generator according to the voltage difference value between the actual voltage and the set voltage of the equipment to be pressurized/reduced voltage, which is measured by the calibration equipment, so that the voltage of the equipment to be pressurized/reduced voltage reaches the target voltage.
On the basis of the above embodiment, a specific manner of obtaining the corresponding relationship between the voltage difference and the set voltage and the duty ratio in the signal compensation method provided by the present application is described below with reference to fig. 4. Fig. 4 is a schematic interaction flow diagram of another embodiment of a signal compensation method provided in the present application. As shown in fig. 4, the signal compensation method provided by this embodiment may include:
s401, the control device sends at least two groups of test parameters to the pulse signal generator, wherein each group of test parameters comprises test set voltage and test duty ratio.
Correspondingly, the pulse signal generator receives at least two groups of test parameters output by the control equipment.
In the test stage, the control device can output different test parameters to the pulse signal generator so that the pulse signal generator outputs pulse signals according to the different test parameters, and under the scene, the calibration device measures the actual test voltage output by the equipment to be pressurized/depressurized under different test parameters, so as to obtain the corresponding relation between the voltage difference and the set voltage and duty ratio.
In this embodiment, the control device outputs at least two sets of test parameters to the pulse signal generator. And each group of test parameters comprises test set voltage and test duty ratio.
S402, the pulse signal generator outputs the pulse signals corresponding to each group of test parameters under each group of test parameters.
In this embodiment, after the pulse signal generator receives each group of test parameters output by the control device, the pulse signal generator may output a pulse signal corresponding to each group of test parameters according to each group of test parameters. The manner in which the pulse signal generator outputs the pulse signal corresponding to each group of test parameters according to each group of test parameters may specifically refer to related descriptions in the prior art, which is not described herein again.
S403, the calibration equipment obtains a test voltage difference value corresponding to each group of test parameters in at least two groups of test parameters of the equipment to be pressurized/depressurized.
Correspondingly, under each set of test parameters, after the pulse signal generator outputs the pulse signal to the equipment to be pressurized/depressurized, the equipment to be pressurized/depressurized can output the corresponding test actual voltage.
In this embodiment, the calibration device may obtain a test actual voltage corresponding to each of at least two sets of test parameters of the device to be pressurized/depressurized. Correspondingly, the calibration device may further determine a difference between the actual test voltage corresponding to each group of test parameters and the set test voltage in each group of test parameters as a test voltage difference corresponding to each group of test parameters.
In one possible implementation, as shown in fig. 1, the test actual voltage may be determined according to the actual waveform output by the device to be pressurized/depressurized under each set of test parameters in the present embodiment. Alternatively, the voltage corresponding to the last waveform drop may be used as the test actual voltage, as shown in a in fig. 1. Correspondingly, the test voltage difference corresponding to each set of test parameters is the difference of the test actual voltage, as shown by Δ V in the figure.
S404, the calibration equipment obtains a corresponding relation according to the at least two groups of test parameters and the test voltage difference value corresponding to each group of test parameters.
Fig. 5A is a graph of a test duty cycle versus a test actual voltage provided by the present application. The test duty cycle versus test actual voltage is shown in fig. 5A. For example, in the present embodiment, the test is performed with the test set voltage of 4V to 20V and the test duty ratio of 0.01% to 100.00%. The relation curve of the test duty ratio and the test actual voltage is the corresponding relation between the test duty ratio and the test actual voltage, which is obtained by taking the test duty ratio as an abscissa and taking the test actual voltage as an ordinate.
Fig. 5B is a graph illustrating a relationship between a test voltage difference and a test set voltage. Correspondingly, after the calibration equipment obtains the test voltage difference value corresponding to each group of test parameters, a relation curve between the test voltage difference value corresponding to each group of test parameters and the test set voltage in each group of test parameters can be obtained. Specifically, in this embodiment, the test setting voltage in each group of test parameters is used as the abscissa, and the test voltage difference corresponding to each group of test parameters is used as the ordinate, so as to obtain the corresponding relationship between the test setting voltage and the test voltage difference under different test duty ratios. Wherein the different test duty cycles comprise the test duty cycle in each set of test parameters.
Correspondingly, the corresponding relationship between the test set voltage and the test voltage difference value under different test duty ratios in this embodiment is the corresponding relationship between the voltage difference value and the set voltage and the duty ratio in the above embodiment.
For example, fig. 5B shows a relationship curve between the test voltage difference corresponding to each set of test parameters and the test set voltage in each set of test parameters, for example, when the duty ratio is 0.05%, 0.1%, 0.2%, 0.3% under the condition that the test set voltage is 4V-20V. That is, it can be obtained in fig. 5B that under the same test set voltage and the same test voltage difference, the "correspondence between the voltage difference and the set voltage and the duty ratio" corresponding to different test duty ratios is different, that is, the correspondence between the voltage difference and the set voltage and the duty ratio is characterized as follows: and testing the corresponding relation between the set voltage and the test voltage difference under different test duty ratios. The correspondence relationship between the voltage difference value, the setting voltage, and the duty ratio in this embodiment may be as shown in fig. 5B.
Fig. 5C is a graph of another test voltage difference versus test set voltage provided by the present application. As shown in fig. 5C, in a possible implementation manner, in this embodiment, the test duty ratio may be further integrated to obtain a corresponding relationship between an integral value of the test duty ratio and a quotient of the test duty ratio on the abscissa, so as to implement quantitative evaluation.
It should be understood that the implementation steps in S401 to S405 in the present embodiment are not performed each time the pulse signal is compensated, but are performed before the pulse signal is compensated.
S405, the calibration equipment sends the corresponding relation to the pulse signal generator.
Correspondingly, the pulse signal generator receives a corresponding relationship, wherein the corresponding relationship is the corresponding relationship between the voltage difference value and the set voltage and the duty ratio.
S406, the calibration device measures the current actual voltage output by the device to be pressurized/depressurized.
S407, the calibration device calculates a current voltage difference between the current actual voltage and the current set voltage of the device to be pressurized/depressurized.
S408, the calibration device feeds the current voltage difference value back to the pulse signal generator.
It should be understood that, in this embodiment, the implementation manners in S406 to S408 may specifically refer to the relevant descriptions in S301 to S403 in the foregoing embodiment, and are not described herein again.
And S409, determining a target corresponding relation from the corresponding relations by the pulse signal generator according to the current voltage difference value, the current duty ratio and the current set voltage.
As shown in fig. 5B, under the same test set voltage and the same test voltage difference, the "voltage difference corresponding to different test duty ratios" is different from the corresponding relationship between the set voltage and the duty ratio ". In this embodiment, the pulse signal generator determines the target corresponding relationship among the plurality of corresponding relationships shown in fig. 5B according to the current voltage difference, the current duty ratio, and the current set voltage.
The corresponding relation representation of the voltage difference value, the set voltage and the duty ratio is as follows: and testing the corresponding relation between the set voltage and the difference value of the test voltage under different test duty ratios. In this embodiment, a corresponding relationship, which is the same as the current voltage difference, the current duty ratio, and the current set voltage, in the corresponding relationship may be determined as the target corresponding relationship. That is, the voltage difference, duty ratio and set voltage corresponding to the target correspondence are respectively the same as the current voltage difference, current duty ratio and current set voltage.
For example, as shown in fig. 5B, if it is determined that the current voltage difference is 1.0V, the current duty ratio is 0.3%, and the current set voltage is 12V, it is determined that the target correspondence relationship is a curve corresponding to the duty ratio of 0.3%.
S410, the pulse signal generator determines a target set voltage according to the target corresponding relation, and the difference between the target set voltage and the voltage difference value in the target corresponding relation is the current set voltage.
Since the duty ratio is not changed after the pulse signal generator is set, the current duty ratio value in this embodiment is not changed. In this embodiment, after the pulse signal generator determines the target corresponding relationship, the pulse signal generator may determine the target setting voltage according to the target corresponding relationship. In the target corresponding relationship, the difference between the voltage difference corresponding to the target setting voltage and the target setting voltage is the current setting voltage. In other words, if the user inputs the target set voltage, the actual voltage output by the device to be pressurized/depressurized is the current set voltage.
For example, if the original set voltage is 10V, the target set voltage determined according to the above method may be 12V, and the voltage difference corresponding to the target set voltage is 2V, so that the actual voltage output by the device to be pressurized/depressurized is 10V.
And S411, the pulse signal generator compensates the pulse signal according to the target set voltage.
In this embodiment, the pulse signal generator may compensate the pulse signal output to the device to be pressurized/depressurized according to the target set voltage. Specifically, the pulse signal generator outputs a pulse signal corresponding to the target set voltage, so that the actual voltage of the device to be pressurized/depressurized is the current set voltage, and the device to be pressurized/depressurized actually outputs the current set voltage.
