[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] Referring to Figure 1 is a flowchart of a high gray scale debugging method based on voltage control according to an embodiment of the present application, comprising:

[0048] S1, obtaining a target gray scale and attributes of an electronic paper to be debugged;

[0049] Specifically, the attributes of the electronic paper to be debugged include the type and hardware characteristics of the electronic paper to be debugged. The target gray scale represents the gray scale to be reached by the electronic paper to be debugged, such as 20 gray scales.

[0050] S2, determining a target voltage value corresponding to the target gray scale according to the target gray scale and a preset gray scale-voltage mapping table;

[0051] Specifically, the construction of the preset gray scale-voltage mapping table comprises:

[0052] obtaining a gray scale increase amount corresponding to each test voltage per unit time and the test voltage;

[0053] determining a corresponding relationship between each test voltage and a gray scale value according to the gray scale increase amount and the test voltage;

[0054] constructing a gray scale-voltage mapping table according to the corresponding relationship between each test voltage and the gray scale value.

[0055] In a preferred embodiment of the present application, the gray scale increase amount corresponding to each test voltage per unit time and the test voltage can be obtained through a test experiment. For example, the change of the gray scale under the condition of 10v; the change of the gray scale under the condition of 12v; the change of the gray scale under the condition of 15v. The change of the gray scale, i.e. the gray scale increase amount, can also be obtained under other test voltages. For example, the gray scale increases by 4 per unit time under the condition of 10v, and the gray scale increases by 3 when it is close to the maximum brightness; the gray scale increases by 5 per unit time under the condition of 12v, and the gray scale increases by 4 when it is close to the maximum brightness; the gray scale increases by 6 per unit time under the condition of 15v, and the gray scale increases by 5 when it is close to the maximum brightness. Therefore, if it is desired to reach the gray scale 16 as soon as possible, 15v for 2 unit times and 10v for 1 unit time are the fastest according to the above. Then, the corresponding relationship between each test voltage and the gray scale value is determined according to the gray scale increase amount and the test voltage, and finally the gray scale-voltage mapping table is constructed according to the corresponding relationship between each test voltage and the gray scale value.

[0056] S3, determining a target voltage value corresponding to the target gray scale according to the target gray scale and a preset gray scale-voltage mapping table;

[0057] Specifically, the most suitable voltages for black and white particles are +15V and -15V, but this does not mean that other voltages are unusable. The electronic paper membrane is designed for 30V operation, so applying +20V and -10V will not affect its lifespan. The electronic paper's driver chip currently operates at 60V, so the entire circuit will not be affected by overvoltage. Black and white particles also exhibit the characteristic that the higher the voltage, the stronger the electric field and the faster the particle speed; conversely, the lower the voltage, the weaker the electric field and the slower the particle speed. Therefore, it is necessary to determine the base voltage value of the electronic paper to be debugged and the corresponding debugging mode.

[0058] S4. Calculate the driving voltage value of the electronic paper to be debugged based on the debugging mode, the base voltage value, and the target voltage value;

[0059] Preferably, the debugging mode includes: a first debugging mode for characterizing the fixed controlled voltage of the particle and a second debugging mode for characterizing the fixed base voltage;

[0060] Based on the debugging mode, the base voltage value, and the target voltage value, the driving voltage value of the electronic paper to be debugged is calculated, including:

[0061] When the debugging mode is the first debugging mode, a first voltage difference value is calculated to characterize the base voltage difference based on the particle controlled voltage corresponding to the first debugging mode and the target voltage value; wherein, the particle controlled voltage includes the black particle controlled voltage and the white particle controlled voltage;

[0062] The driving voltage value of the electronic paper to be debugged is calculated based on the first voltage difference and the base voltage value.

[0063] Specifically, grayscale adjustment operations are performed on the electronic paper to be adjusted based on the driving voltage value and the target grayscale, including:

[0064] When the debugging mode is the first debugging mode, grayscale debugging is performed on the base voltage value of the electronic paper to be debugged according to the driving voltage value, so that the electronic paper to be debugged can reach the target grayscale.

[0065] In a preferred embodiment of the present application, the common voltage for driving white and black particles (i.e., particle controlled voltage) of the electronic paper is +15v and -15v, and there is a base voltage (Vcom voltage). By adjusting the value of the base voltage (Vcom voltage), the movement of black and white particles per unit time is changed. For example, if Vcom is set to 5v, then the input particle controlled voltage is +15v and -15v, and the reference voltage relative to Vcom will be +10v and -20v. Thus, the white particle controlled voltage becomes +10v, which is smaller, and the white particle moves more slowly, and similarly, the black particle -20v, the voltage becomes larger (in absolute value), and the black particle moves faster. By adjusting the Vcom to change the particle movement speed, the gray scale of the electronic paper to be adjusted is more convenient and faster to adjust. For example Figure 2 As shown in the first control mode, the particle controlled voltage +15v and -15v voltage is fixed, and the first voltage difference value for representing the base voltage difference value is calculated, and according to the first voltage difference value and the base voltage value, the driving voltage value of the electronic paper to be adjusted is calculated, and then the appropriate driving voltage value is selected at the "voltage selection" to perform gray scale adjustment on the driving chip of the electronic paper to be adjusted. First, the voltage modification of Vcom is relatively small, mainly responsible for weak adjustment. For example: gray scale 20 changes to 21. If you want to change the gray scale 20 to 25, you still need to use large voltage adjustment. For example, +15v voltage adjustment 1 unit time can increase 20 brightness to 25 brightness, then set a small voltage, for example: +10v, 1 unit time can only increase 20 brightness to 22.5 brightness, and then set a smaller voltage +5v, then 1 unit time can only increase 20 brightness to 21v.

[0066] Through the first adjustment mode, the adjustment is allowed under the condition that the particle controlled voltage is fixed, so that the adjustment process can be optimized according to the characteristics of different electronic papers, especially in the case that the particle response characteristics are known or relatively stable, the target gray scale can be more effectively achieved. In the first adjustment mode, the driving voltage value is determined by calculating the base voltage difference value (i.e., the difference between the target voltage value and the particle controlled voltage). This method can more accurately control the voltage distribution on the electronic paper, thereby optimizing the gray scale display effect. Compared with adjusting the base voltage and the particle controlled voltage at the same time, fixing the particle controlled voltage and adjusting only the base voltage difference value can simplify the adjustment process, reduce the number of parameters to be adjusted, and thus reduce the complexity and uncertainty of the adjustment. Since the adjustment process is more direct and explicit (i.e., fixing the particle controlled voltage and adjusting the base voltage difference value), the target gray scale can be converged more quickly, and the adjustment efficiency is improved.

[0067] S5、According to the driving voltage value and the target gray scale, the gray scale of the electronic paper to be adjusted is adjusted to achieve the target gray scale.

[0068] Specifically, further comprising:

[0069] In a case where the debugging mode is the second debugging mode, a second voltage difference value for characterizing the particle controllable voltage difference value is calculated according to the basic voltage corresponding to the second debugging mode and the target voltage value; wherein the second voltage difference value includes a positive voltage difference value and a negative voltage difference value;

[0070] According to the second voltage difference value and the basic voltage value, a driving voltage value of the electronic paper to be debugged is calculated.

[0071] Specifically, in a case where the debugging mode is the second debugging mode, a gray scale debugging operation is performed on the positive voltage and the negative voltage of the electronic paper to be debugged according to the driving voltage value, so that the electronic paper to be debugged reaches the target gray scale.

[0072] In a preferred embodiment of the present application, the particle controllable voltage is adjusted by an external switching circuit. 10v and 5v are externally provided in addition to 15v, and Vcom is fixed (the basic voltage is fixed). 15v, 10v and 5v are controlled by the control pin of the main control end to be connected to the electronic paper driving chip, and then the position of the moving particle is quickly completed by different voltages and appropriate adjustment speed. That is, as shown in the figure, the basic voltage is fixed, the positive voltage difference value and the negative voltage difference value are calculated, and then the driving voltage value is calculated according to the positive voltage difference value, the negative voltage difference value and the basic voltage value, and the positive voltage and the negative voltage of the electronic paper to be debugged are regulated according to the driving voltage value. Figure 3 Figure 3 The core controller needs to output multiple voltages from the power supply chip in the power supply unit through SPI or other I I C, serial port and other instructions. The core controller has a voltage waveform file of the refreshing process. When starting to refresh the black and white picture, the corresponding voltage waveform file is found to check the voltage and time in it. The voltage selection module is controlled by the voltage and time data to switch the voltage. For example, in the first debugging mode, Vcom is-5, and the positive and negative voltages are +-15v. The equivalent voltage on the diaphragm is 20v and-10v. In the second debugging mode, Vcom is fixed at 0v, and the positive and negative voltages are +-10v. The equivalent voltage on the diaphragm is still +-10v. Finally, the equivalent voltage on the diaphragm is-10v, and the effect generated by the diaphragm is equivalent, and the gray scale change per unit time is the same. The greater the voltage, the higher the gray scale effect per unit time.

[0073] ​In the second debugging mode, by calculating the positive voltage difference and the negative voltage difference respectively, the movement state of the black and white particles on the electronic paper can be more accurately controlled, so that the target gray scale can be more accurately reached. This fine voltage control helps to improve the display accuracy and gray scale performance of the electronic paper. In the case of fixed basic voltage, by adjusting the controllable voltage difference of the particles to adapt to the characteristics of different electronic papers, the universality and adaptability of the embodiment are enhanced, so that the debugging process can be optimized for different models and specifications of electronic papers.

[0074] In another preferred embodiment of the present application, the target gray scale is 22. If the gray scale is not regulated using the method of the embodiment, the gray scale is completed under the condition of conventional unmodified voltage, such as Figure 4 In the case of reverse waveform, first go up to exceed the gray scale 22 to reach 23, and then let the white particles run in reverse by reverse voltage, and return to 22. If the gray scale is regulated using the method of the embodiment, the voltage is modified, and the voltage waveform is as follows Figure 5 : The waveform of the modified weak voltage. As long as the weak voltage is used at the last positive voltage, the movement speed of the white particles is reduced, so that the gray scale is only 22, and will not exceed 22 as in the case of Figure 4 unmodified voltage, after one positive voltage period, it directly reaches the gray scale 23, exceeding 22.

[0075] By implementing the embodiment, the target gray scale and the attributes of the electronic paper to be debugged are obtained; according to the target gray scale and the preset gray scale voltage mapping table, the target voltage value corresponding to the target gray scale is determined; according to the attributes of the electronic paper to be debugged, the basic voltage value of the electronic paper to be debugged and the corresponding debugging mode are determined; according to the debugging mode, the basic voltage value and the target voltage value, the driving voltage value of the electronic paper to be debugged is calculated; according to the driving voltage value and the target gray scale, the gray scale debugging operation is performed on the electronic paper to be debugged, so that the electronic paper to be debugged reaches the target gray scale. Through the preset gray scale voltage mapping table, the voltage value corresponding to the target gray scale can be quickly determined, avoiding the tedious process of manual debugging or experimental debugging, so that the driving voltage value calculated according to the corresponding debugging mode is used to perform gray scale debugging on the electronic paper to be debugged, reducing the manual operation debugging time, and significantly improving the high gray scale debugging efficiency of the electronic paper.
