[0042] The present application can also be embodied in a different way or be applied to different specific embodiments, and the details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the scope of protection of the present application.

[0043] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and only show the components related to the present application in the drawings, not according to the number, shape and size of the components in actual implementation. The shape, number and ratio of each component in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0044] The present application will be described with reference to the attached drawings and preferred embodiments to provide an overall understanding of the present application. Those skilled in the art will readily understand other advantages and / or uses of the present application from the description of the preferred embodiments given hereinafter. The present application can be implemented or performed in different ways without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating, not for limiting, the scope of the present application.

[0045] Electronic paper generally includes a TFT glass substrate, a pixel electrode and a transparent electrode (common electrode), a transparent PET film, and microcapsules sandwiched between the pixel electrode and the transparent electrode. The microcapsules are extremely small (e.g., about 100 um) and have a surface that easily adsorbs electric charges. The microcapsules also have uniformly arranged dyed charged particles therein. Under the action of an applied electric field, the dyed charged particles in the microcapsules can move in different directions. For example, the microcapsules can be filled with white positive charges and black negative charges. When a positive voltage is applied to the pixel electrode, the white particles with positive charges move toward the transparent electrode (generally the top of the display) due to the repulsion of like charges, and the black particles with negative charges move toward the pixel electrode. Thus, the human eye ultimately sees a white picture composed of white particles.

[0046] As can be seen from the structure of the electronic paper, the movement of the particles in the microcapsules can be controlled by applying different voltages between the pixel electrode and the transparent electrode. The transparent electrode is applied with a Vcom voltage, which is generally a fixed voltage and serves as a reference value for the voltage that controls the movement of the particles in the microcapsules. When a positive voltage greater than the Vcom voltage is applied to the pixel electrode, the white particles move toward the transparent electrode. The longer the voltage is applied, the more white particles will gather on the transparent electrode side, and the higher the gray scale will be. Similarly, when a negative voltage lower than the Vcom voltage is applied to the pixel electrode, the black particles move toward the transparent electrode. The longer the voltage is applied, the lower the gray scale will be. Thus, the size of the gray scale of the electronic paper is determined by the length of time for which the voltage is applied.

[0047] Regarding the driving control method of the electronic paper in the related art, first, the element itself of the electronic paper has a characteristic: self-fading. After the particles in the microcapsules move and display a gray scale under the action of an electric field (e.g., from gray scale A to gray scale B), if the applied electric field is removed, although the overall system is stable, the gray scale will decay to gray scale C due to the characteristics of the particles, and cannot be completely maintained.

[0048] In the direct refresh mode, the initial gray scale X can be directly refreshed to the target gray scale Y. However, due to the self-fading characteristic, the current initial gray scale X is actually gray scale X', and the final displayed gray scale is not the target gray scale Y but gray scale Y'. That is, the actual displayed gray scale is not the gray scale we want.

[0049] In some indirect refresh modes, the initial gray scale X is first driven to the pure black gray scale or the pure white gray scale, which is equivalent to the reference gray scale. Because the change of the gray scale is no longer affected by the time when the reference gray scale is reached, the initial gray scale X is first pulled to the reference gray scale, and then driven to the target gray scale Y from the reference gray scale. However, the indirect mode also has disadvantages. That is, the farther the target gray scale Y is from the reference gray scale, the longer the time of applying the voltage. Because the particle movement has an inertia characteristic, the longer the time under the electric field, the more obvious the inertia characteristic. The particle movement needs to be accurately controlled to stop at the corresponding position to display the correct gray scale. Therefore, the longer the time of applying the voltage, the more difficult to control. Therefore, it is difficult to accurately stop at the target gray scale in the indirect mode. In other indirect refresh modes, in order to solve the problem of the above indirect refresh mode, the initial gray scale X is first pulled to the pure black gray scale, and then pulled to the pure white gray scale, so as to shorten the time of reaching the target gray scale through two reference gray scales.

[0050] Although the above indirect refresh mode can improve the refresh effect to a certain extent, it increases the distance of the particle movement, lengthens the time of applying the voltage, and lengthens the overall refresh time, so that the human eye can see the entire refresh process of the electronic paper product (for example, the entire process from the initial gray scale to the pure black gray scale, from the pure black gray scale to the pure white gray scale, and from the pure white gray scale to the target gray scale), which affects the display effect and use experience of the electronic paper.

[0051] Embodiments of the present disclosure provide a driving control method of electronic paper and an electronic device. In the embodiments, a first reference gray scale and a second reference gray scale can be defined first. In the driving control process of the electronic paper, the gray scale of the current frame that is closest to the reference gray scale can be analyzed first, and the gray scale of the next frame that is closest to the reference gray scale can be analyzed. Then, based on the analysis results, a suitable driving control strategy can be selected to drive the electronic paper to display the target gray scale in the next frame. That is, the embodiments can determine the difference between the initial gray scale and the target gray scale and the reference gray scale first, so as to determine the refresh direction, shorten the time of driving control of the electronic paper, improve the response speed of the electronic paper, and improve the display effect.

[0052] Embodiment one

[0053] The embodiments provide a driving control method of electronic paper, which can be applied to an electronic device with electronic paper. As shown in Figure 1 The method can include:

[0054] S110, obtaining an initial gray scale and a target gray scale of the electronic paper; wherein the initial gray scale is a gray scale of a current frame of the electronic paper, and the target gray scale is a gray scale of a next frame of the electronic paper;

[0055] S120, determining, from the first reference gray scale and the second reference gray scale, a first target reference gray scale closest to the initial gray scale, and a second target reference gray scale closest to the target gray scale; wherein the first reference gray scale is greater than the second reference gray scale;

[0056] S130, driving the electronic paper to display the target gray scale in the next frame according to the first target reference gray scale and the second target reference gray scale.

[0057] In step S110, the gray scale of the current frame refers to a gray scale at which the electronic paper is currently in. The gray scale of the next frame refers to a gray scale at which the electronic paper needs to be in in the next frame.

[0058] In the electronic device starts to display after power-on, since the electronic paper is characterized by displaying by reflecting light, as long as the ambient light is bright, the picture can be displayed, therefore, when the power is on, the algorithm controller can read the gray scale of the current frame and the gray scale of the next frame. Then, the read gray scale of the current frame is recorded as the initial gray scale, and the read gray scale of the next frame is recorded as the target gray scale. That is, in the driving control method, the gray scale of the electronic paper needs to be controlled from the initial gray scale to the target gray scale.

[0059] It should be noted that the gray scale of the current frame and the gray scale of the next frame can be read simultaneously, or sequentially or in reverse order, which is not limited.

[0060] In step S120, the first reference gray scale and the second reference gray scale can be configured in advance to facilitate the driving control of the electronic paper. The first reference gray scale can be greater than the second reference gray scale, but the specific gray scales of the first reference gray scale and the second reference gray scale can be set according to actual needs, which is not limited. For example, the first reference gray scale can be a pure white gray scale, and the second reference gray scale can be a pure black gray scale.

[0061] In this step, the initial gray scale and the target gray scale can be analyzed to determine, from the first reference gray scale and the second reference gray scale, a reference gray scale closest to the initial gray scale, recorded as the first target reference gray scale, and a reference gray scale closest to the target gray scale, recorded as the second target reference gray scale.

[0062] If the first target reference gray scale and the second target reference gray scale are the same reference gray scale, it is indicated that the reference gray scale close to the initial gray scale and the target gray scale is the same reference gray scale, so the electronic paper can be first driven from the initial gray scale to the same reference gray scale, and then driven from the same reference gray scale to the target gray scale, so that the movement distance of the dyeing particles in the electronic paper is the shortest, the time is the shortest, and the effect is better.

[0063] For example, if the first target reference gray scale and the second target reference gray scale are both the first reference gray scale, the TCON chip (Timing Controller chip, which is a control circuit for a liquid crystal display screen, used for managing and controlling the timing, refresh rate and pixel data of the display screen) can first drive the electronic paper from the initial gray scale to the first reference gray scale, and then drive the electronic paper from the first reference gray scale to the target gray scale.

[0064] For another example, if the first target reference gray scale and the second target reference gray scale are both the second reference gray scale, the TCON chip can first drive the electronic paper from the initial gray scale to the second reference gray scale, and then drive the electronic paper from the second reference gray scale to the target gray scale.

[0065] In this step, if the first target reference gray scale and the second target reference gray scale are different reference gray scales, it is indicated that the reference gray scale close to the initial gray scale and the target gray scale is different reference gray scale, so the electronic paper can be first driven from the initial gray scale to any reference gray scale, and then driven from the reference gray scale moved from the initial gray scale to the target gray scale.

[0066] For example, if the first target reference gray scale is the first reference gray scale, and the second target reference gray scale is the second reference gray scale, the TCON chip can first drive the electronic paper from the initial gray scale to any reference gray scale of the first reference gray scale and the second reference gray scale, and then drive the electronic paper from the reference gray scale moved from the initial gray scale to the target gray scale.

[0067] For another example, if the first target reference gray scale is the second reference gray scale, and the second target reference gray scale is the first reference gray scale, the TCON chip can first drive the electronic paper from the initial gray scale to any reference gray scale of the first reference gray scale and the second reference gray scale, and then drive the electronic paper from the reference gray scale moved from the initial gray scale to the target gray scale.

[0068] It should be noted that when the first target reference gray scale and the second target reference gray scale are different reference gray scales, no matter which reference gray scale is selected as the intermediate gray scale for driving and controlling the initial gray scale to the target gray scale, the movement distance of the dyeing particles in the electronic paper is the same, and the time is also the same, which can include a shorter driving refresh time.

[0069] In this embodiment, the first reference gray scale and the second reference gray scale can be defined first, and in the driving control process of the electronic paper, the reference gray scales with close gray scale distances of the current frame can be analyzed first, and the reference gray scales with close gray scale distances of the next frame are analyzed, and then based on the analysis results, a suitable driving control strategy is selected to drive the electronic paper to display the target gray scale of the next frame. That is, the embodiment can determine the difference between the initial gray scale and the target gray scale and the reference gray scale, so as to determine the refresh direction, shorten the driving control time of the electronic paper, improve the response speed of the electronic paper, and improve the display effect.

[0070] Embodiment two

[0071] The embodiment provides a driving control method of an electronic paper, which can be applied to an electronic device with the electronic paper. As shown in Figure 2 The method can include:

[0072] S210, obtaining an initial gray scale and a target gray scale of the electronic paper; wherein the initial gray scale is a gray scale of a current frame of the electronic paper, and the target gray scale is a gray scale of a next frame of the electronic paper;

[0073] S220, obtaining a basic gray scale; wherein the basic gray scale is an average value of the first reference gray scale and the second reference gray scale;

[0074] S230, determining a first target reference gray scale according to the basic gray scale and the initial gray scale;

[0075] S240, determining a second target reference gray scale according to the basic gray scale and the target gray scale;

[0076] S250, driving the electronic paper to display the target gray scale of the next frame according to the first target reference gray scale and the second target reference gray scale.

[0077] The step S210 can refer to the step S110 in the embodiment one, and will not be repeated here. The step S250 can refer to the step S130 in the embodiment one, and will not be repeated here.

[0078] In the step S220, after the configuration of the first reference gray scale and the second reference gray scale is completed, the configuration of the basic gray scale can be performed based on the first reference gray scale and the second reference gray scale. The average value of the first reference gray scale and the second reference gray scale can be taken as the basic gray scale.

[0079] For example, the first reference gray scale can be a pure white gray scale with a gray scale value of 16, and the second reference gray scale can be a pure black gray scale with a gray scale value of 0. At this time, a gray scale with a gray scale value of 8 can be determined as the basic gray scale.

[0080] It should be noted that in addition to the above-mentioned determination of the configuration of the basic gray scale, the basic gray scale can also be configured by other ways, which are not limited.

[0081] In step S230, the first target reference gray level can be determined based on the difference between the initial gray level and the base gray level, or based on the ratio of the initial gray level to the base gray level, or by other manners, which are not limited.

[0082] For example, if the difference between the initial gray level and the base gray level is greater than or equal to zero, the first target reference gray level can be determined as the first reference gray level (e.g. the pure white gray level). If the difference between the initial gray level and the base gray level is less than zero, the first target reference gray level can be determined as the second reference gray level (e.g. the pure black gray level).

[0083] For another example, if the ratio of the initial gray level to the base gray level is greater than or equal to 1, the first target reference gray level can be determined as the first reference gray level. If the ratio of the initial gray level to the base gray level is less than 1, the first target reference gray level can be determined as the second reference gray level.

[0084] It should be noted that the first target reference gray level can be determined by other manners besides the above manners, which are not limited.

[0085] In step S240, the second target reference gray level can be determined based on the difference between the target gray level and the base gray level, or based on the ratio of the target gray level to the base gray level, or by other manners, which are not limited.

[0086] For example, if the difference between the target gray level and the base gray level is greater than or equal to zero, the second target reference gray level can be determined as the first reference gray level (e.g. the pure white gray level). If the difference between the target gray level and the base gray level is less than zero, the second target reference gray level can be determined as the second reference gray level (e.g. the pure black gray level).

[0087] For another example, if the ratio of the target gray level to the base gray level is greater than or equal to 1, the second target reference gray level can be determined as the first reference gray level. If the ratio of the target gray level to the base gray level is less than 1, the second target reference gray level can be determined as the second reference gray level.

[0088] It should be noted that the second target reference gray level can be determined by other manners besides the above manners, which are not limited.

[0089] In this embodiment, the average of the first reference gray scale and the second reference gray scale can be configured as a base gray scale, and then the reference gray scale closest to the initial gray scale is determined based on the relationship between the base gray scale and the initial gray scale, and the reference gray scale closest to the target gray scale is determined based on the relationship between the base gray scale and the target gray scale, so as to determine the refresh direction, shorten the time length of the driving control of the electronic paper, improve the response speed of the electronic paper, and improve the display effect.

[0090] Embodiment Three

[0091] The embodiment provides a driving control method of electronic paper, which can be applied to an electronic device with electronic paper.

[0092] It should be noted that when the first target reference gray scale and the second target reference gray scale are different reference gray scales, the distance of the movement of the dyeing particles in the electronic paper is the same, and the time length is also the same, which can all include a shorter time length of driving refresh. However, the distance from the reference gray scale to the target gray scale is shorter, and since the distance from the initial gray scale to the reference gray scale does not actually affect the final display gray scale, the electronic paper can be driven to move from the initial gray scale to the second target reference gray scale first, and then driven to move from the second target reference gray scale to the target gray scale, so as to shorten the refresh time and improve the refresh rate, and better improve the display effect.

[0093] For example, if the first target reference gray scale is the first reference gray scale and the second target reference gray scale is the second reference gray scale, the TCON chip can first drive the electronic paper to move from the initial gray scale to the second reference gray scale, and then drive the electronic paper to move from the second reference gray scale to the target gray scale.

[0094] For another example, if the first target reference gray scale is the second reference gray scale and the second target reference gray scale is the first reference gray scale, the TCON chip can first drive the electronic paper to move from the initial gray scale to the first reference gray scale, and then drive the electronic paper to move from the first reference gray scale to the target gray scale.

[0095] The embodiment can better improve the display effect while shortening the refresh time and improving the refresh rate.

[0096] Embodiment Four

[0097] The embodiment provides a driving control method of electronic paper, which can be applied to an electronic device with electronic paper. Figure 3 As shown in the reference

[0098] S310, acquire an initial gray scale and a target gray scale of the electronic paper; wherein the initial gray scale is a gray scale of a current frame of the electronic paper, and the target gray scale is a gray scale of a next frame of the electronic paper;

[0099] S320, acquire a basic gray scale; wherein the basic gray scale is an average value of a pure white gray scale and a pure black gray scale;

[0100] S330, determine a first target reference gray scale according to the basic gray scale and the initial gray scale;

[0101] S340, determine a second target reference gray scale according to the basic gray scale and the target gray scale;

[0102] S350, drive the electronic paper to display the target gray scale in the next frame according to the first target reference gray scale and the second target reference gray scale.

[0103] The step S310 can refer to the step S210 in Embodiment Two, and details are not repeated here.

[0104] In the step S320, the average value of the pure white gray scale and the pure black gray scale can be configured as the basic gray scale. For example, the gray scale value of the pure white gray scale can be recorded as 16, the gray scale value of the pure black gray scale can be recorded as 0, and the gray scale value of the basic gray scale can be configured as 8.

[0105] It should be noted that, in addition to the above-mentioned configuration of the basic gray scale, the basic gray scale can also be configured by other ways, which are not limited.

[0106] In the step S330, if the difference between the initial gray scale and the basic gray scale is greater than or equal to zero, the first target reference gray scale can be determined as the pure white gray scale. If the difference between the initial gray scale and the basic gray scale is less than zero, the first target reference gray scale can be determined as the pure black gray scale.

[0107] It should be noted that, in addition to the above-mentioned determination of the first target reference gray scale, the first target reference gray scale can also be determined by other ways, which are not limited.

[0108] In the step S340, if the difference between the target gray scale and the basic gray scale is greater than or equal to zero, the second target reference gray scale can be determined as the pure white gray scale. If the difference between the target gray scale and the basic gray scale is less than zero, the second target reference gray scale can be determined as the pure black gray scale.

[0109] It should be noted that, in addition to the above-mentioned determination of the second target reference gray scale, the second target reference gray scale can also be determined by other ways, which are not limited.

[0110] If the first target reference gray scale and the second target reference gray scale are both the pure white gray scale, it indicates that in the pure white gray scale and the pure black gray scale, the initial gray scale and the target gray scale are both closer to the pure white gray scale. The TCON chip can first drive the electronic paper to move from the initial gray scale to the pure white gray scale, and then drive the electronic paper to move from the pure white gray scale to the target gray scale, so as to shorten the time length of the driving control of the electronic paper, improve the reaction speed of the electronic paper, and improve the display effect.

[0111] If the first target reference gray scale and the second target reference gray scale are both the pure black gray scale, it indicates that in the pure white gray scale and the pure black gray scale, the initial gray scale and the target gray scale are both closer to the pure black gray scale. The TCON chip can first drive the electronic paper to move from the initial gray scale to the pure black gray scale, and then drive the electronic paper to move from the pure black gray scale to the target gray scale, so as to shorten the time length of the driving control of the electronic paper, improve the reaction speed of the electronic paper, and improve the display effect.

[0112] If the first target reference gray scale is the pure white gray scale and the second target reference gray scale is the pure black gray scale, it indicates that the initial gray scale is closer to the pure white gray scale, and the target gray scale is closer to the pure black gray scale. Since the length of the distance from the initial gray scale to the reference gray scale does not actually affect the final displayed gray scale, the TCON chip can first drive the electronic paper to move from the initial gray scale to the pure black gray scale, and then drive the electronic paper to move from the pure black gray scale to the target gray scale, so as to shorten the refresh time and improve the refresh rate, and better improve the display effect.

[0113] For another example, if the first target reference gray scale is the pure black gray scale and the second target reference gray scale is the pure white gray scale, it indicates that the initial gray scale is closer to the pure black gray scale, and the target gray scale is closer to the pure white gray scale. Since the length of the distance from the initial gray scale to the reference gray scale does not actually affect the final displayed gray scale, the TCON chip can first drive the electronic paper to move from the initial gray scale to the pure white gray scale, and then drive the electronic paper to move from the pure white gray scale to the target gray scale, so as to shorten the refresh time and improve the refresh rate, and better improve the display effect.

[0114] In this embodiment, the pure white gray scale and the pure black gray scale can be defined as reference gray scales, and the average of the pure white gray scale and the pure black gray scale can be configured as a basic gray scale. In the driving control process of the electronic paper, the reference gray scales closer to the gray scale of the current frame can be analyzed, and the reference gray scales closer to the gray scale of the next frame can be analyzed, and then based on the analysis results, a suitable driving control strategy is selected to drive the electronic paper to display the target gray scale in the next frame. That is, this embodiment can first determine the difference between the initial gray scale and the target gray scale and the reference gray scale, so as to determine the refresh direction, shorten the time length of the driving control of the electronic paper, improve the reaction speed of the electronic paper, and improve the display effect.
