[0047] It should be noted that the drawings included herewith are included to illustrate only specific embodiments of the application and are not intended to limit the scope of the application which is defined by the appended claims. The drawings are included herewith to facilitate understanding of the concepts disclosed herein and the concepts disclosed herein include all techniques possessing the same basic concepts, regardless of their inherent capabilities or whether they can be better or worse than the examples included herewith.
[0048] The above and other advantages and features of the present application will become apparent from the following description of the preferred embodiments with reference to the accompanying drawings. It is to be understood, however, that the drawings are designed solely for the purpose of illustration and not as a definition of the limits of the application, for which reference should be made only to the appended claims. Additionally, variations to the embodiments disclosed can be understood and effected within the broad scope of the application, and therefore the detailed description of the preferred embodiments are not meant to limit the scope of the application, but is merely the easiest way of teaching the industrial applicability of the present application to those who are skilled in the art.
[0049] 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 dye-charged particles therein. When an electric field is applied, the dye-charged particles in the microcapsules move in different directions. For example, when white positive charges and black negative charges are filled in the microcapsules, and a positive voltage is applied to the pixel electrode, the white particles having positive charges move toward the transparent electrode (generally the top of the display) due to the repulsion of like charges, and the black particles having negative charges move toward the pixel electrode. Thus, the human eye ultimately sees a white screen composed of white particles.
[0050] From the structure of the electronic paper, it can be known that the particle movement in the microcapsule can be controlled as long as different voltages are applied between the pixel electrode and the transparent electrode, and the transparent electrode is applied with the Vcom voltage. The Vcom voltage can generally be a fixed voltage, which is equivalent to a reference value of the voltage for controlling the particle movement in the microcapsule. When the pixel electrode is applied with a positive voltage greater than the Vcom voltage, the white particles move towards the transparent electrode, and the longer the time length of the applied voltage, the more white particles are gathered on the transparent electrode side, and the higher the displayed gray scale. Similarly, when the pixel electrode is applied with a negative voltage lower than the Vcom voltage, the black particles move towards the transparent electrode, and the longer the time length of the applied voltage, the lower the gray scale. Therefore, the size of the gray scale of the electronic paper is determined according to the time length of the applied voltage.
[0051] The self-fading phenomenon of the electronic paper refers to that, after the particles in the microcapsule move to the expected position under the action of the electric field and display the required gray scale, the driving system controls the driving signal (the gate signal) to be closed, that is, the driving voltage is removed, and the gray scale is maintained under the action of the capacitance. However, due to the characteristics of the microcapsule particles, after the driving voltage is removed, the particles move towards the low-voltage direction and finally result in that the gray scale after the driving voltage is removed is lower than the expected gray scale, so that the displayed gray scale of the electronic paper is lower than the expected gray scale.
[0052] In the related art, the initial gray scale is first pulled to the reference gray scale, and then the reference gray scale starts to move towards the target gray scale, so that the influence of the inconsistency between the initial gray scale and the actual gray scale caused by the self-fading phenomenon can be avoided, and the problem of the difference between the target gray scale and the actual gray scale is improved. However, this scheme can only eliminate the influence of the actual gray scale difference caused by the initial gray scale difference. Due to the existence of the self-fading phenomenon, the actual gray scale displayed after each driving control still has a difference with the target gray scale, and the display effect is poor. In addition, since the driving voltage is fixed and unchanged, the distance of the particle movement when the initial gray scale is pulled to the reference gray scale is lengthened, resulting in that the refresh time is lengthened, the reaction time is lengthened, and the power consumption when the particle movement is controlled is increased, thereby resulting in a poor experience.
[0053] Embodiments of the present disclosure provide a driving control method and device of an electronic paper and electronic equipment. In the embodiments, corresponding driving information can be configured for different initial gray scales and target gray scales. The driving information can include driving voltage information, that is, different initial gray scales and target gray scales can be configured with different driving voltage information, so that the refresh experience can be better improved, the time length of the driving control of the electronic paper can be shortened, and the reaction speed of the electronic paper can be improved. In addition, the target driving information corresponding to the target driving information in the configuration information can improve the adverse effects of the self-fading phenomenon, so that the gray scale after the driving control matches the target gray scale after the self-fading, and the display effect is improved.
[0054] Embodiment one
[0055] The embodiment provides a driving control method of electronic paper, which can be applied to an electronic device with electronic paper. Referring to Figure 1 The method can include:
[0056] S110, obtaining target gray scale information of the electronic paper;
[0057] S120, determining target driving information corresponding to the target gray scale information from configuration information based on the target gray scale information;
[0058] S130, driving the electronic paper to be at a target gray scale in a next frame based on the target driving information.
[0059] In step S110, the target gray scale information refers to gray scale information corresponding to current driving control, which can include an initial gray scale and a target gray scale. The initial gray scale is a gray scale of a current frame of the electronic paper, and the gray scale of the current frame refers to a gray scale at which the electronic paper is currently in the current frame. The target gray scale is a gray scale of a next frame of the electronic paper, and the gray scale of the next frame refers to a gray scale at which the electronic paper needs to be in the next frame.
[0060] In step S110, the target gray scale information refers to gray scale information corresponding to current driving control, which can include an initial gray scale and a target gray scale. The initial gray scale is a gray scale of a current frame of the electronic paper, and the gray scale of the current frame refers to a gray scale at which the electronic paper is currently in the current frame. The target gray scale is a gray scale of a next frame of the electronic paper, and the gray scale of the next frame refers to a gray scale at which the electronic paper needs to be in the next frame.
[0061] It should be noted that the gray scale of the current frame and the gray scale of the next frame can be read at the same time, or can be read sequentially or in reverse order, and no limitation is made to this.
[0062] In step S120, the target driving information is used to drive the electronic paper to be at the target gray scale in the next frame. That is, the electronic paper is driven and controlled using the target driving information, which can eliminate the influence of the self-fading phenomenon, so that the electronic paper is finally stabilized at the target gray scale in the target gray scale information.
[0063] In step S120, the target driving information is used to drive the electronic paper to be at the target gray scale in the next frame. That is, the electronic paper is driven and controlled using the target driving information, which can eliminate the influence of the self-fading phenomenon, so that the electronic paper is finally stabilized at the target gray scale in the target gray scale information.
[0064] In the driving information corresponding to each gray scale information of the configuration information, the driving information can include driving voltage information. That is, in this method, corresponding driving voltage information can be configured for each gray scale information, that is, the driving voltage in this method is no longer a fixed voltage, but is adaptively configured according to the target gray scale information.
[0065] In the driving information corresponding to each gray scale information of the configuration information, the driving information can include driving voltage information. That is, in this method, corresponding driving voltage information can be configured for each gray scale information, that is, the driving voltage in this method is no longer a fixed voltage, but is adaptively configured according to the target gray scale information.
[0066] In step S130, after the target driving information is found and determined from the configuration information, the electronic paper can be controlled based on the target driving information, and the electronic paper can be driven to the target gray scale in the next frame. That is, the target driving information can drive the electronic paper to move from the initial gray scale to the first gray scale, the first gray scale is higher than the target gray scale, and then after the self-fading phenomenon, the first gray scale falls to the target gray scale, so that the electronic paper is finally maintained at the target gray scale, to achieve good display effect.
[0067] In this embodiment, corresponding driving information can be configured for different initial gray scales and target gray scales, and the driving information can include driving voltage information. That is, different initial gray scales and target gray scales can be configured with different driving voltage information, which can better improve the refresh experience, shorten the driving control time of the electronic paper, and improve the response speed of the electronic paper. Moreover, the target driving information corresponding to the target driving information in the configuration information can improve the adverse effects of the self-fading phenomenon, so that the gray scale after driving control matches the target gray scale after self-fading, thereby improving the display effect.
[0068] Embodiment Two
[0069] The embodiment provides a driving control method of electronic paper, which can be applied to an electronic device with electronic paper. In the method, driving information can include invalid driving duration information and valid driving duration information, and driving voltage information can include a driving voltage. The invalid driving duration information can represent a duration of applying the driving voltage, for example, the invalid driving duration information can include a width corresponding to a single pulse corresponding to the driving voltage (i.e., a duration of the single pulse) and a number of pulses. The valid driving duration information can represent a duration of applying the driving voltage, for example, the valid driving duration information can include an application duration of the driving voltage.
[0070] It should be noted that the display driving of the electronic paper needs to follow the direct current (DC) balance principle, that is, the number of pulses used by the electronic paper from gray scale A to gray scale B and the number of pulses used by the electronic paper from gray scale B to gray scale A are equal, and the directions are opposite, so that irreversible damage of the microcapsule particles to one direction movement caused by long-time application of an electric field or accumulation of an electric field in one direction can be avoided. Based on the above DC balance principle, it can be known that the final gray scale is related to the effective duration of driving, and it is also known that the applied driving voltage will affect the final gray scale reached.
[0071] In the related art, for example, as shown in a pulse schematic diagram corresponding to the related art in the Figure 2 , driving control is generally performed in the form of pulses with a fixed driving voltage. It is assumed that the current gray scale is gray scale A, and the target gray scale is gray scale B. If the effective pulse number of gray scale A is m (for example, 1 in the Figure 2 ), the effective pulse number of gray scale B is n (for example, 1 in the Figure 2 ), and the pulse number from the pure black gray scale to the pure white gray scale is x (for example, 2 in the Figure 2 ). In the driving control process from gray scale A to the pure black gray scale, the number of pulse pairs corresponding to the positive pulse and the negative pulse (1 and -1 in the figure form a pair) can be a (for example, 2 pairs in the Figure 2 ). In the duration of the a pulse pairs, the particles move up and down, but the overall effect is that the particles are not moving, and only in the last m pulse duration, the particles will move from gray scale A to the pure black gray scale, and the m pulse duration is the effective driving duration. In the driving control process from the pure black gray scale to the pure white gray scale, there can be y pairs (for example, 1 pair in the Figure 2 ) of pulse pairs that are positive and negative balanced, and after the gray scale reaches the pure white gray scale, x positive pulses can be continuously applied (at this time, the gray scale has reached the reference gray scale, and the continuously applied pulses will not change the gray scale value), and part of the pulses (for example, 1) are used to offset the m pulses in the last stage. In the driving control process from the pure white gray scale to gray scale B, there can be b pairs (for example, 1 pair in the Figure 2In the above-mentioned embodiment, the particle is still floating at the position of the pure white gray scale under the action of the first pair of pulses, and under the action of the last n negative pulses, the particle moves to the pure black gray scale and finally reaches the gray scale B, and the length of the n pulses at this time is just enough to offset the remaining part (for example, 1) of the length of the above-mentioned x pulses, so that in the whole particle movement process, although the gray scale changes from the gray scale A to the gray scale B, the overall pulse maintains DC balance.
[0072] As Figure 2 As shown in the pulse schematic diagram corresponding to the second embodiment, the driving voltage in this embodiment can be greater than the driving voltage in the above-mentioned related art, and the driving voltage is configured with corresponding pulse width, number of invalid pulses, length of valid pulses and the like. When the driving voltage is increased, although the particle is relatively stationary within a pair of pulse lengths, the higher voltage can increase the activity of the particle, and the length of the valid pulse required by the particle to reach the pure black gray scale after the activity is increased, that is, the length of the invalid driving is reduced, and the number of pulse pairs can also be reduced. In addition, since the driving voltage is increased, the length of the valid driving can also be shortened, so that the reaction length of the particle in the whole driving control process can be shortened, the refresh rate can be improved, and the display effect can be improved.
[0073] It should be noted that the driving voltage, pulse width, number of invalid pulses and length of valid pulses and the like of the driving information corresponding to the gray scale information can be determined through simulation test, and details are not described herein.
[0074] Embodiment three
[0075] The embodiment provides a driving control method of electronic paper, which can be applied to electronic devices with electronic paper. The difference between this embodiment and the second embodiment is that the driving voltage information can include invalid driving voltage and valid driving voltage, that is, each gray scale information can correspond to two driving voltages (invalid driving voltage and valid driving voltage).
[0076] The invalid driving voltage and the valid driving voltage can be the same (at this time, it is equivalent to that the gray scale information corresponds to one driving voltage) or different, and details are not limited herein. For example, in the configuration information, the invalid driving voltage corresponding to the same gray scale information and the valid driving voltage can be set to be greater than or equal to the valid driving voltage.
[0077] The invalid driving voltage and the valid driving voltage can be the same (at this time, it is equivalent to that the gray scale information corresponds to one driving voltage) or different, and details are not limited herein. For example, in the configuration information, the invalid driving voltage corresponding to the same gray scale information and the valid driving voltage can be set to be greater than or equal to the valid driving voltage.
[0078] The determination of the effective driving voltage can be performed by gradually reducing the voltage through simulation experiments, observing whether the particles can reach the target gray scale in the same effective driving duration, and finding the critical voltage when the particles cannot completely reach the target gray scale in the effective pulse duration. The value of the effective driving voltage cannot be reduced below the critical voltage in the effective pulse duration. Finally, the specific value of the reduction can be selected according to actual requirements, for example, the final judgment can be made during actual use.
[0079] It should be noted that, in the configuration information, the effective driving voltage corresponding to the same gray scale information and the effective driving duration information are negatively correlated. That is, the greater the effective driving voltage, the smaller the effective driving duration; and the smaller the effective driving voltage, the greater the effective driving duration.
[0080] In the configuration information, the effective driving voltage corresponding to the same gray scale information and the effective driving duration information are negatively correlated. That is, the greater the effective driving voltage, the smaller the effective driving duration; and the smaller the effective driving voltage, the greater the effective driving duration.
[0081] The specific values of the ineffective driving voltage and the effective driving voltage can be selected according to actual conditions, and no further determination is made.
[0082] In this embodiment, by using a higher ineffective driving voltage and a lower effective driving voltage, the duration of the entire driving control can be reduced, the refresh rate can be improved, and the power consumption can be maintained.
[0083] Embodiment Four

The configuration information includes a corresponding relationship between at least one gray scale information and driving information. The driving information includes driving voltage information.

[0089] The driving voltage information includes invalid driving voltage and valid driving voltage. In the configuration information, the invalid driving voltage corresponding to the same gray scale information is greater than or equal to the valid driving voltage.
[0090] In the configuration information, the invalid driving voltage corresponding to the same gray scale information is negatively correlated with the duration represented by the invalid driving duration information.
[0091] In the configuration information, the valid driving voltage corresponding to the same gray scale information is negatively correlated with the duration represented by the valid driving duration information.
[0092] In this embodiment, corresponding driving information can be configured for different initial gray scales and target gray scales. The driving information can include driving voltage information, that is, different initial gray scales and target gray scales can be configured with different driving voltage information, which can better improve the refresh experience, shorten the duration of electronic paper driving control, and improve the response speed of electronic paper. Moreover, the target driving information corresponding to the target driving information in the configuration information can improve the adverse effects of self-fading, so that the gray scale after driving control matches the target gray scale after self-fading, thereby improving the display effect.
