Bistable liquid crystal displays, such as cholesteric liquid crystal displays (Cholesteric Liquid Crystal Display; Ch-LCD), have bi-stable characteristics, and after the cholesteric liquid crystal rotates a certain angle (that is, displays a picture), it can maintain the picture for a long time without re-applying the voltage signal. It is often used in temperature sensor displays, e-books, e-paper, electronic whiteboards and other products. Among them, the two stable state characteristics (P state and FC state) of the bistable liquid crystal in the bistable liquid crystal display are used to display and maintain the picture for a long time.

These drawings and the accompanying text are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of this application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION
[0055] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
[0056] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.
[0057] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "at the time of," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the described features, steps, operations, elements, components, items, types, and / or groups, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, meaning any one or any combination. Thus, “A, B, or C” or “A, B, and / or C” means “any of: A; B; C; A and B; A and C; B and C; A, B, and C.” An exception to this definition occurs only when a combination of elements, functions, steps, or operations are inherently mutually exclusive in some manner.
[0058] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.
[0059] It should be noted that in this article, step codes such as S102 and S103 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial restriction on the order. When implementing the step, those skilled in the art may execute S103 first and then S102, etc., but these should all be within the scope of protection of this application.
[0060] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.
[0061] See Figure 1 , is a display control method provided in an embodiment of the present application. The method can be executed by a display device provided in an embodiment of the present application, and the display device can be implemented in software and / or hardware.
[0062] The display control method provided in this embodiment includes the following steps:
[0063] S11: receiving color image data;
[0064] S12: Processing the color image data according to an image processing strategy corresponding to the type of the bistable liquid crystal panel to obtain target image data that meets the display requirements of the bistable liquid crystal panel, wherein the data processing includes data structure processing and / or grayscale value conversion processing;
[0065] S13: Determine the stable type information corresponding to each pixel in the target image data to support display control of the bistable liquid crystal panel.
[0066] In one embodiment, the image format used by the color image data is a relatively mature image format, such as bmp format, jpeg format, PNG format, etc.
[0067] In one embodiment, the color image data may represent image data composed of at least R, G, and B color data. It is understood that the color image data may form a pure color image (e.g., a white image, a black image, etc.) or a color image depending on the specific data of the R, G, and B colors.
[0068] In one embodiment, the image processing strategy may represent various data processing flows or various data processing means for converting color image data that cannot adapt to the display requirements of the bistable liquid crystal display panel into target image data that meets the display requirements.
[0069] In one embodiment, the data architecture processing within the image processing strategy may represent various data processing methods for converting the pixel format, file structure, and other data architectures within color image data into a standard data architecture corresponding to a bi-stable liquid crystal panel. The data architecture may represent the organization of image data during storage and processing, and may include, in addition to the pixel format and file structure, the encoding of color information, image resolution, and other aspects. The pixel format may represent the pixel arrangement and / or the specific format in which each pixel stores color information. The file structure may represent the organization of an image file, such as the organization of the file header, source data, and actual image data.
[0070] In one embodiment, the grayscale value conversion process in the image processing strategy may represent various data processing methods for converting color information in color image data into grayscale values suitable for the display requirements of a bi-stable liquid crystal panel, such as color space conversion, grayscale mapping, and grayscale value gain. Specifically, color space conversion may represent converting the RGB color space used by the color image data into a color space suitable for a bi-stable liquid crystal panel. For example, the RGB color space used by the color image data represents three colors: R, G, and B, while the color space used by a pure color bi-stable liquid crystal panel represents only one color. Specifically, grayscale mapping may represent mapping the color value of each pixel in the color image data to a preset grayscale range supported by the bi-stable liquid crystal panel. Specifically, grayscale value gain may represent combining the grayscale values corresponding to each color of each pixel in the color image data with corresponding gain coefficients to support better color space conversion or to enable the bi-stable liquid crystal panel to better determine the stability type.
[0071] In one embodiment, the types of bistable liquid crystal panels include but are not limited to pure color bistable liquid crystal panels, color-resistance bistable liquid crystal panels, etc. Figure 2 , each pixel in a pure color bistable liquid crystal panel includes only one color of bistable liquid crystal, Figure 2The color of the bistable liquid crystal in the pixel can be, but is not limited to, any one of red (i.e., Red, R color), green (i.e., Green, G color), and blue (i.e., Blue, B color). At least some of the pixels in the color-resistance bistable liquid crystal panel include bistable liquid crystal of one color and at least one color resist of another color. Figure 3 The bistable liquid crystal of the middle pixel is red in color and has green and blue color resistances.
[0072] In one embodiment, since different types of bistable liquid crystal panels can display different types of colors and have different display requirements, different types of bistable liquid crystal panels may correspond to different image processing strategies.
[0073] In one embodiment, data architecture processing includes but is not limited to at least one of the following:
[0074] Deleting data irrelevant to the standard data structure in the image data to update the image data;
[0075] The order of the R color grayscale value, the G color grayscale value, and the B color grayscale value corresponding to each pixel in the image data is adjusted to be consistent with the color order in the standard data architecture to update the image data.
[0076] For example, the pixel format of the standard data architecture only includes R grayscale values, G grayscale values, and B grayscale values. In this way, after deleting data in the image data (such as color image data) that is not related to the standard data architecture, the pixel format in the image data can be consistent with the pixel format of the standard data architecture, thereby facilitating subsequent reprocessing of the R grayscale values, G grayscale values, and B grayscale values (for example, grayscale value merging and averaging, grayscale value gain processing followed by merging, etc.). Taking a white screen with a bistable liquid crystal panel display resolution of 2200 (RGB) * 1650 as an example (within the grayscale value range of L0 to L255, the grayscale value corresponding to the white screen is L255, i.e., FF), see Figure 4 When the pixel format of the standard data architecture only includes R color grayscale value, G color grayscale value, and B color grayscale value, and the image format of the color image data is BMP format, when the pixel format in the color image data includes G color grayscale value, B color grayscale value, NC data, and R color grayscale value, the NC data in the pixel structure can be deleted so that the pixel format in the color image data can be consistent with the pixel format of the standard data architecture.
[0077] For example, the color sequence in the pixel format of the standard data architecture is R grayscale value, G grayscale value, and B grayscale value. In this way, the color sequence of each pixel in the image data is adjusted to R grayscale value, G grayscale value, and B grayscale value in sequence to keep consistent with the color sequence in the pixel format of the standard data architecture, so as to facilitate subsequent reprocessing of the R grayscale value, G grayscale value, and B grayscale value (for example, grayscale value gain processing followed by merging processing, etc.). Taking a white screen with a bistable liquid crystal panel display resolution of 2200 (RGB) * 1650 as an example (within the grayscale value range of L0 to L255, the grayscale value corresponding to the white screen is L255, i.e. FF), see Figure 5 When the color order in the pixel format of the standard data architecture is R color grayscale value, G color grayscale value, and B color grayscale value, the color order in the pixel format of the color image data is G color grayscale value, B color grayscale value, and R color grayscale value, which is adjusted to R color grayscale value, G color grayscale value, and B color grayscale value to be consistent with the color order in the pixel format of the standard data architecture.
[0078] It should be understood that the color order in the pixel format of the standard data architecture can be, but is not limited to, R color grayscale value, G color grayscale value, and B color grayscale value in sequence. It can be adjusted according to the design of the bistable liquid crystal panel. For example, the color order in the pixel format of the standard data architecture can be B color grayscale value, R color grayscale value, and G color grayscale value in sequence; for another example, the color order in the pixel format of the standard data architecture can be G color grayscale value, B color grayscale value, and R color grayscale value in sequence.
[0079] In one embodiment, the grayscale value conversion process corresponding to the pure color bistable liquid crystal panel includes at least one of the following:
[0080] Multiplying the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel in the image data by the corresponding gain coefficient to update the image data, wherein the sum of the gain coefficients corresponding to the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel is 1;
[0081] The R color grayscale value, the G color grayscale value, and the B color grayscale value corresponding to each pixel in the image data are merged to obtain a target grayscale value corresponding to each pixel in the image data.
[0082] In one embodiment, the gain coefficients corresponding to the R grayscale value, G grayscale value, and B grayscale value of each pixel are used to adjust the gain ratio of the three RGB colors to achieve a better display effect later.
[0083] For example, the grayscale conversion process for a pure color bistable liquid crystal panel includes the following two steps: multiplying the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel in the image data by the corresponding gain coefficient to update the image data; and merging the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel in the updated image data to obtain the target grayscale value corresponding to each pixel in the image data, thereby obtaining the target image data. Taking a white screen with a resolution of 2200 (RGB)*1650 as an example (within the grayscale value range of L0 to L255, the grayscale value corresponding to the white screen is L255, i.e., FF), see Figure 6 For a pure color bistable liquid crystal panel, the gain coefficients corresponding to the associated R, G, and B grayscale values are x, y, and z (x+y+z=1), respectively. The R, G, and B grayscale values corresponding to each pixel in the image data are multiplied by the corresponding gain coefficients to obtain FF*x, FF*y, and FF*z, respectively, thereby updating the image data. FF*x, FF*y, and FF*z corresponding to each pixel in the updated image data are added together (i.e., the merging process is summed) to obtain a target grayscale value FF corresponding to each pixel in the image data, thereby obtaining the target image data. In this way, the technical solution of this embodiment can perform gain processing on the R, G, and B grayscale values, and then convert them into target grayscale values, thereby improving the display effect of the pure color bistable liquid crystal panel on the picture.
[0084] For example, the grayscale conversion process for a pure-color bistable liquid crystal panel includes a step of summing and averaging the R, G, and B grayscale values corresponding to each pixel in the image data (i.e., the merging process includes summing and averaging) to obtain a target grayscale value corresponding to each pixel in the image data. Thus, the technical solution of this embodiment can improve the display quality of a pure-color bistable liquid crystal panel in a simple manner.
[0085] In one embodiment, the grayscale value conversion process corresponding to the color-resistance bistable liquid crystal panel includes:
[0086] According to the image color-stable type relationship table corresponding to the bistable liquid crystal panel and the image color information corresponding to the image data, at least one of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the image data is symmetrically inverted within a preset grayscale range to update the image data.
[0087] It should be understood that the image color-stable type relationship table corresponding to the color-resistance bi-stable liquid crystal panel includes the corresponding relationship between the image color and the stable type. Figure 3 、 Figure 7The color-resistance bistable liquid crystal panel includes red bistable liquid crystal, green color resistance and blue color resistance. The factory-preset image color-stable type relationship table is shown in Table 1 below:
[0088]
[0089] Here, R (liquid crystal) represents the stable state type of the region of the red bistable liquid crystal.
[0090] Here, G (color resist) represents the stable state type of the region of the bistable liquid crystal covered by the green color resist.
[0091] Wherein, B (color resist) represents the stable state type of the region of the bistable liquid crystal covered by the blue color resist.
[0092] Among them, P represents the planar state; FC represents the focal conic state.
[0093] For example, a white screen with a color resistive bistable liquid crystal panel displaying a resolution of 800 (RGB) * 480 is taken as an example (within the grayscale value range of L0 to L255, the grayscale value corresponding to the white screen is L255, i.e. FF), see Table 1 and Figure 7, the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the pixel format of the color image data corresponding to the white screen are all FF, and the image color-stable type relationship table 1 corresponding to the color-resistance bistable liquid crystal panel needs to determine the stable state type of the red bistable liquid crystal area as P state, the stable state type of the bistable liquid crystal area covered by the green color resist as FC state, and the stable state type of the bistable liquid crystal area covered by the blue color resist as FC state. Since the stable state type of the red bistable liquid crystal area is different from that of the green color resist, the stable state type of the bistable liquid crystal area covered by the blue color resist is FC state. The stable type of the region of the bistable liquid crystal covered by the green color resist is different from the stable type of the region of the bistable liquid crystal covered by the blue color resist. Therefore, the R color grayscale value corresponding to the region of the red bistable liquid crystal in each pixel in the color image data can be symmetrically inverted to 00 (that is, the grayscale value range is L0 to L255, L255 is symmetrically taken as L0, expressed as 00), and the G color grayscale value corresponding to the region of the bistable liquid crystal covered by the green color resist and the B color grayscale value corresponding to the region of the bistable liquid crystal covered by the blue color resist remain unchanged (F F), thereby obtaining the target image data; or the R color grayscale value corresponding to the area of the red bistable liquid crystal in each pixel in the color image data can be kept unchanged (FF), and the G color grayscale value corresponding to the area of the bistable liquid crystal covered by the green color resist and the B color grayscale value corresponding to the area of the bistable liquid crystal covered by the blue color resist are both stacked and inverted (that is, the grayscale value range is L0 to L255, L255 is symmetrically taken as L0, expressed as 00), thereby obtaining the target image data; further, when the display control is subsequently performed according to the target image data, according to the difference between the R color grayscale value corresponding to the area of the red bistable liquid crystal in each pixel in the color image data and the G color grayscale value corresponding to the area of the bistable liquid crystal covered by the green color resist and the B color grayscale value corresponding to the area of the bistable liquid crystal covered by the blue color resist, a P state waveform can be transmitted to the area of the red bistable liquid crystal to form a P state, and an FC state waveform can be transmitted to the area of the bistable liquid crystal covered by the green color resist and the area of the bistable liquid crystal covered by the blue color resist to form an FC state.
[0094] It should be understood that the purpose of the above examples, which focus on white images, is to help better understand the concept of the technical solution of this embodiment. Therefore, the technical solution of this embodiment is not limited to processing color image data representing white images, but can also process color image data representing various other pure color images or multi-color images. Taking the grayscale value range of L0 to L255 as an example, the grayscale value of each pixel in the color image data representing various other pure color images or multi-color images can be any value between L0 and L255. In addition, the grayscale value range of L0 to L255 in the technical solution of this embodiment is used as an example, but is not limited to this. It can be any grayscale value range that can be achieved or reached by current or future technology.
[0095] In one embodiment, the bistable liquid crystal panel may include, in addition to the two stable states, a transient state, ie, an H state (Homeotropic State), for increasing the switching speed between the P state and the FC state.
[0096] In one embodiment, when the type of the bistable liquid crystal panel is a pure color bistable liquid crystal panel, the image processing strategy includes but is not limited to:
[0097] Performing data architecture processing on the color image data to obtain first image data of a target architecture, where the target architecture is a standard data architecture corresponding to a bistable liquid crystal panel;
[0098] Perform grayscale value conversion processing on the RGB data corresponding to each pixel in the first image data to obtain target image data, where the target image data includes a target grayscale value corresponding to each pixel; or
[0099] Grayscale value conversion processing is performed according to the RGB data corresponding to each pixel in the color image data to obtain target image data, which includes the target grayscale value corresponding to each pixel.
[0100] For example, for a pure color bistable liquid crystal panel, when the data structure of the color image data does not match the standard data structure corresponding to the pure color bistable liquid crystal panel, the color image data can be first processed by data structure processing (for example, deleting data in the color image data that is not related to the standard data structure, adjusting the order of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the color image data to be consistent with the color order in the standard data structure) and converted into the standard data structure corresponding to the pure color bistable liquid crystal panel to obtain the first image data; and then performing grayscale value conversion processing according to the RGB data corresponding to each pixel in the first image data. Processing (for example, multiplying the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the first image data by the corresponding gain coefficient respectively, and then merging the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the first image data to obtain the target grayscale value corresponding to each pixel in the target image data, or directly merging the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the first image data to obtain the target grayscale value corresponding to each pixel in the target image data) to obtain the target image data (the target image data includes the target grayscale value corresponding to each pixel).
[0101] Exemplarily, for a pure color bistable liquid crystal panel, when the data architecture of the color image data does not match the standard data architecture corresponding to the pure color bistable liquid crystal panel, grayscale value conversion processing can be first performed based on the RGB data corresponding to each pixel in the color image data to obtain fifth image data (the fifth image data includes the target grayscale value corresponding to each pixel); then the fifth image data is subjected to data architecture processing (for example, data in the fifth image data that is not related to the standard data architecture is deleted) and converted into the standard data architecture corresponding to the pure color bistable liquid crystal panel to obtain the target image data.
[0102] Exemplarily, for a pure color bistable liquid crystal panel, when the data architecture of the color image data matches the standard data architecture corresponding to the pure color bistable liquid crystal panel, grayscale value conversion processing is performed according to the RGB data corresponding to each pixel in the color image data to obtain target image data, which includes the target grayscale value corresponding to each pixel.

Furthermore, the stability type information corresponding to each pixel in the target image data can be determined to support display control of the bistable liquid crystal panel. Thus, the technical solution of this embodiment enables processing color image data to adapt to the display requirements of a pure color bistable liquid crystal panel, thereby supporting display control of the bistable liquid crystal panel.
[0104] In one embodiment, when the type of the bistable liquid crystal panel is a color-resistance bistable liquid crystal panel, the image processing strategy includes but is not limited to:

[0107] According to the image color-stable type relationship table corresponding to the bistable liquid crystal panel and the image color information corresponding to the third image data, grayscale value conversion processing is performed on the RGB data corresponding to each pixel in the third image data to obtain target image data, which includes target grayscale data corresponding to each pixel.
[0108] Exemplarily, for a color-resistance bistable liquid crystal panel, when the data structure of the color image data does not match the standard data structure corresponding to the color-resistance bistable liquid crystal panel, the color image data can be first processed with the data structure (for example, data irrelevant to the standard data structure in the color image data is deleted, and the order of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the color image data is adjusted to be consistent with the color order in the standard data structure) and converted into the standard data structure corresponding to the color-resistance bistable liquid crystal panel to obtain third image data; and based on the image color information represented by the third image data and the image color-stability type relationship table corresponding to the color-resistance bistable liquid crystal panel, it is determined whether the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the third image data can be directly When the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel are met, the third graphic data can be directly used as the target image data, and the display control is performed according to the R color grayscale value corresponding to the R color area of each pixel in the target image data, the G color grayscale value corresponding to the G color area, the B color grayscale value corresponding to the B color area, and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel, so as to transmit one of the P-state waveform and the FC-state waveform to the R color area of each pixel in the color-resistance bistable liquid crystal panel, transmit one of the P-state waveform and the FC-state waveform to the G color area of each pixel in the color-resistance bistable liquid crystal panel, and transmit one of the P-state waveform and the FC-state waveform to the B color area of each pixel in the color-resistance bistable liquid crystal panel.

The RGB data is grayscale converted (for example, at least one of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the third image data is symmetrically inverted within a preset grayscale range) to obtain target image data, so that the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the target image data can directly correspond to the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel, thereby according to the R color area corresponding to each pixel in the target image data The color grayscale value, the G color grayscale value corresponding to the G color area, the B color grayscale value corresponding to the B color area, and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel are displayed and controlled, so as to transmit one of the P-state waveform and the FC-state waveform to the R color area of each pixel in the color-resistance bistable liquid crystal panel, transmit one of the P-state waveform and the FC-state waveform to the G color area of each pixel in the color-resistance bistable liquid crystal panel, and transmit one of the P-state waveform and the FC-state waveform to the B color area of each pixel in the color-resistance bistable liquid crystal panel.
[0110] In one embodiment, when the type of the bistable liquid crystal panel is a color-resistance bistable liquid crystal panel, the image processing strategy includes but is not limited to:
[0111] performing grayscale value conversion processing on RGB data corresponding to each pixel in the color image data according to the image color-stability type relationship table corresponding to the bistable liquid crystal panel and the image color information corresponding to the color image data to obtain fourth image data, the fourth image data including target grayscale data corresponding to each pixel;
[0112] The fourth image data is used as the target image data; or,
[0113] Data architecture processing is performed according to the fourth image data to obtain target image data of a target architecture, where the target architecture is a standard data architecture corresponding to a bistable liquid crystal panel.
[0114] For example, for a color-resistance bistable liquid crystal panel, when the data structure of the color image data matches the standard data structure corresponding to the color-resistance bistable liquid crystal panel, and based on the image color information represented by the color image data and the image color-stability type relationship table corresponding to the color-resistance bistable liquid crystal panel, it is determined that the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the color image data can directly correspond to the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel, the color graphic data can be directly used as the target image data, and according to the target image The R color grayscale value corresponding to the R color area of each pixel in the image data, the G color grayscale value corresponding to the G color area, the B color grayscale value corresponding to the B color area, and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel are displayed and controlled, so as to transmit one of the P-state waveform and the FC-state waveform to the R color area of each pixel in the color-resistance bistable liquid crystal panel, transmit one of the P-state waveform and the FC-state waveform to the G color area of each pixel in the color-resistance bistable liquid crystal panel, and transmit one of the P-state waveform and the FC-state waveform to the B color area of each pixel in the color-resistance bistable liquid crystal panel.
[0115] Exemplarily, for a color-resistance bistable liquid crystal panel, when the data structure of the color image data matches the standard data structure corresponding to the color-resistance bistable liquid crystal panel, and based on the image color information represented by the color image data and the image color-stability type relationship table corresponding to the color-resistance bistable liquid crystal panel, it is determined that the R color grayscale value, the G color grayscale value, and the B color grayscale value of each pixel in the color image data cannot correspond to the display control requirements of the R color area, the G color area, and the B color area of each pixel in the color-resistance bistable liquid crystal panel, then, based on the image color-stability type relationship table corresponding to the color-resistance bistable liquid crystal panel and the image color information corresponding to the color image data, grayscale value conversion processing is performed on the RGB data corresponding to each pixel in the color image data (for example, at least one of the R color grayscale value, the G color grayscale value, and the B color grayscale value corresponding to each pixel in the color image data is converted within a preset grayscale range). The target image data is obtained so that the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the target image data can directly correspond to the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel, thereby performing display control according to the R color grayscale value corresponding to the R color area, the G color grayscale value corresponding to the G color area, and the B color grayscale value corresponding to the B color area in each pixel in the target image data and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel, so as to transmit one of the P-state waveform and the FC-state waveform to the R color area of each pixel in the color-resistance bistable liquid crystal panel, transmit one of the P-state waveform and the FC-state waveform to the G color area of each pixel in the color-resistance bistable liquid crystal panel, and transmit one of the P-state waveform and the FC-state waveform to the B color area of each pixel in the color-resistance bistable liquid crystal panel.
[0116] For example, for a color-resistance bistable liquid crystal panel, when the data structure of the color image data does not match the standard data structure corresponding to the color-resistance bistable liquid crystal panel, and according to the image color information represented by the color image data and the image color-stability type relationship table corresponding to the color-resistance bistable liquid crystal panel, it is determined that the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the color image data cannot correspond to the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel, the color-resistance bistable liquid crystal panel can be used to determine the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel. The method comprises the steps of: performing grayscale value conversion processing on the RGB data corresponding to each pixel in the color image data (for example, symmetrically inverting at least one of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the color image data within a preset grayscale range) to obtain target image data, so that the R color grayscale value, G color grayscale value, and B color grayscale value of each pixel in the target image data can directly correspond to the display control requirements of the R color area, G color area, and B color area of each pixel in the color-resistance bistable liquid crystal panel to obtain fourth image data; then performing data architecture processing on the fourth image data (for example, deleting data in the color image data that is not related to the standard data architecture, adjusting the order of the R color grayscale value, G color grayscale value, and B color grayscale value corresponding to each pixel in the color image data to be consistent with the color order in the standard data architecture) to convert the data into the standard data architecture corresponding to the color-resistance bistable liquid crystal panel to obtain the target image data; finally, performing data architecture processing on the fourth image data according to the R color area in each pixel in the target image data. The corresponding R color grayscale value, the G color grayscale value corresponding to the G color area, the B color grayscale value corresponding to the B color area, and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel are displayed and controlled, so as to transmit one of the P-state waveform and the FC-state waveform to the R color area of each pixel in the color-resistance bistable liquid crystal panel, transmit one of the P-state waveform and the FC-state waveform to the G color area of each pixel in the color-resistance bistable liquid crystal panel, and transmit one of the P-state waveform and the FC-state waveform to the B color area of each pixel in the color-resistance bistable liquid crystal panel.
[0117] The above-described technical solution enables data processing (e.g., data structure processing and / or grayscale value conversion) of received color image data to obtain target image data adapted for the display requirements of a color-resistance bi-stable liquid crystal panel. Furthermore, the stability type information corresponding to each pixel in the target image data can be determined to support display control of the bi-stable liquid crystal panel. Thus, the technical solution of this embodiment enables processing color image data to adapt to the display requirements of a color-resistance bi-stable liquid crystal panel, thereby supporting display control of the bi-stable liquid crystal panel.
[0118] In one embodiment, step S13 may include: determining the steady-state type information of each pixel in the target image data based on the target image data, the steady-state type division threshold and a preset rule, wherein the steady-state type division threshold is within a preset grayscale range; and performing display control on the bistable liquid crystal panel based on the steady-state type information of each pixel in the target image data.
[0119] In one embodiment, the preset rules include but are not limited to one of the following:
[0120] If the grayscale value is greater than or equal to the steady-state type classification threshold, the steady-state type information is determined to be FC type; if the grayscale value is less than the steady-state type classification threshold, the steady-state type information is determined to be P type;
[0121] If the grayscale value is greater than or equal to the steady-state type classification threshold, the steady-state type information is determined to be P type; if the grayscale value is less than the steady-state type classification threshold, the steady-state type information is determined to be FC type.
[0122] In one embodiment, for a pure color bistable liquid crystal panel, the stable type classification threshold can be adjusted according to the display condition, so that the pure color bistable liquid crystal panel displays a better picture after display control is completed.
[0123] In one embodiment, for a color bi-stable liquid crystal panel, the stable-state type classification threshold can be arbitrarily set to ensure that the display control of the target image data satisfies the image color-stable-state type relationship table. It should be understood that properly setting the stable-state type classification threshold can also improve the image displayed by the color resistive bi-stable liquid crystal panel after display control is completed.
[0124] The display control method provided in this embodiment includes the following steps: S11: receiving color image data; S12: performing data processing on the color image data according to the image processing strategy corresponding to the type of the bistable liquid crystal panel to obtain target image data that meets the display requirements of the bistable liquid crystal panel, wherein the data processing includes data structure processing and / or grayscale value conversion processing; S13: determining the stability type information corresponding to each pixel in the target image data to support display control of the bistable liquid crystal panel. Through the technical solution of this embodiment, the received color image data can be processed (e.g., data structure processing and / or grayscale value conversion processing) to obtain target image data that is adapted to the display requirements of the bistable liquid crystal panel, and the stability type information corresponding to each pixel in the target image data can be determined to support display control of the bistable liquid crystal panel. In this way, the technical solution of this embodiment can process color image data to adapt to the display requirements of the bistable liquid crystal panel and support display control of the bistable liquid crystal panel.
[0125] Based on the same inventive concept as the above embodiments, the above embodiments are exemplarily described below through some specific application scenarios:
[0126] Example 1:
[0127] For example, a white screen with a color image data representation resolution of 2200 (RGB) * 1650 (corresponding grayscale value is L255, i.e., FF), a bmp image format for the color image data, a red bistable liquid crystal of a pure color bistable liquid crystal panel, a color sequence of "R color, G color, B color" in the standard data architecture corresponding to the pure color bistable liquid crystal panel, a preset grayscale range of L0 to L255 corresponding to the pure color bistable liquid crystal panel, and a stable type classification threshold of M corresponding to the white screen (M is within the preset grayscale range of L0 to L255) are used. Figure 8 、 Figure 9 This example provides a display control method for the above-mentioned pure color bistable liquid crystal panel, including the steps of:
[0128] S101: receiving color image data in bmp image format;
[0129] S102: deleting NC data in the pixel format of each pixel in the color image data to update the color image data;
[0130] S103: adjusting the color sequence of the pixel format of each pixel in the color image data to be consistent with the color sequence in the standard data architecture, so as to update the color image data;
[0131] Specifically, the color order of the pixel format of each pixel in the color image data is adjusted from G color, B color, R color to R color, G color, B color;
[0132] S104: Multiplying the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel in the color image data by the corresponding gain coefficients x, y, and z, respectively, and adding the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel multiplied by the gain coefficient to obtain a corresponding target grayscale value, thereby obtaining target image data;
[0133] Specifically, the sum of the gain coefficients x, y, and z is 1 (i.e., x+y+z=1), which is used to adjust the influence ratio of the three colors to achieve a better display effect;
[0134] S105: Determine the steady-state type information of each pixel in the target image data according to the target image data, the steady-state type classification threshold and the preset rule, and perform display control on the pure color bistable liquid crystal panel, wherein the preset rule is that if the grayscale value is greater than or equal to M, the steady-state type information is determined to be P type, and if the grayscale value is less than M, the steady-state type information is determined to be FC type.
[0135] Specifically, when the stable-state type information in the display control is P type, the bistable liquid crystal region corresponding to the P type transmits a P state waveform to form a P state, and when the stable-state type information in the display control is FC type, the bistable liquid crystal region corresponding to the FC type transmits an FC state waveform to form an FC state.
[0136] For example, see Figure 10 , x is 0.4, y is 0.3, z is 0.3, M is 128 (80 in hexadecimal), multiplied by the gain coefficient and converted into hexadecimal R color grayscale value, G color grayscale value, B color grayscale value are 66, 4C, 4D respectively; multiplied by the gain coefficient and converted into hexadecimal R color grayscale value, G color grayscale value, B color grayscale value are added to obtain the corresponding target grayscale value FF (greater than M is 128), thereby determining that the steady-state type information is P type, and transmitting the P-state waveform.
[0137] Through the technical solution of this example, color image data in the bmp image format representing a white screen can be processed to adapt to the display requirements of the pure color bistable liquid crystal panel, thereby supporting display control of the pure color bistable liquid crystal panel.
[0138] Example 2:
[0139] For example, a color image data representing a red screen with a resolution of 2200 (RGB)*1650 (corresponding grayscale value is L255, i.e., FF), the color image data format is a bmp image format, the bistable liquid crystal of the pure color bistable liquid crystal panel is red, the color sequence in the standard data architecture corresponding to the pure color bistable liquid crystal panel is "R color, G color, B color", the preset grayscale range corresponding to the pure color bistable liquid crystal panel is L0 to L255, and the stable type classification threshold corresponding to the red screen is M (M is within the preset grayscale range of L0 to L255). See Figure 11 、 Figure 12 This example provides a display control method for the above-mentioned pure color bistable liquid crystal panel, including the steps of:
[0140] S201: receiving color image data;
[0141] S202: Multiplying the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel in the color image data by corresponding gain coefficients x, y, and z, respectively, converting the R grayscale value, G grayscale value, and B grayscale value corresponding to each pixel multiplied by the gain coefficients into hexadecimal, and adding the R grayscale value, G grayscale value, and B grayscale value converted into hexadecimal to obtain a corresponding target grayscale value, thereby obtaining target image data;
[0142] Specifically, the gain coefficients x, y, and z are 0.4, 0.3, and 0.3, respectively, and are used to adjust the influence ratio of the three colors in order to achieve a better display effect;
[0143] S203: Determine the steady-state type information of each pixel in the target image data according to the target image data, the steady-state type classification threshold and the preset rule, and perform display control on the pure color bistable liquid crystal panel, wherein the preset rule is that if the grayscale value is greater than or equal to M, the steady-state type information is determined to be P type, and if the grayscale value is less than M, the steady-state type information is determined to be FC type.
[0144] Specifically, when the stable-state type information in the display control is P type, the bistable liquid crystal region corresponding to the P type transmits a P state waveform to form a P state, and when the stable-state type information in the display control is FC type, the bistable liquid crystal region corresponding to the FC type transmits an FC state waveform to form an FC state.
[0145] Exemplarily, M is 128 (80 in hexadecimal), and the target grayscale value FF (greater than M, which is 128) determines that the steady-state type information is P-type, and a P-state waveform is transmitted.
[0146] Through the technical solution of this example, color image data representing a red screen can be processed to adapt to the display requirements of a pure color bistable liquid crystal panel, thereby supporting display control of the pure color bistable liquid crystal panel.
[0147] Example 3:
[0148] Take the color image data representing a white screen with a resolution of 800 (RGB) * 480 (corresponding to a grayscale value of L255, i.e., FF), the format of the color image data is the bmp image format, a color-resistance bistable liquid crystal panel (including a red bistable liquid crystal, a green color resist, and a blue color resist), the color order in the standard data architecture corresponding to the color-resistance bistable liquid crystal panel is "R color, G color, B color", the preset grayscale range corresponding to the color-resistance bistable liquid crystal panel is L0 to L255, the stable type classification threshold corresponding to the white screen is M (M is within the preset grayscale range of L0 to L255), and the image color-stable type relationship table corresponding to the color-resistance bistable liquid crystal panel is the above-mentioned Table 1 as an example, see. Figure 13 、 Figure 14 This example provides a display control method for the above-mentioned color-resistance bistable liquid crystal panel, including the steps of:

[0151] S303: adjusting the color sequence of the pixel format of each pixel in the color image data to be consistent with the color sequence in the standard data architecture, so as to update the color image data;
[0152] Specifically, the color order of the pixel format of each pixel in the color image data is adjusted from G color, B color, R color to R color, G color, B color;
[0153] S304: According to the image color-steady-state type relationship table, symmetrically invert the R color grayscale value corresponding to each pixel in the color image data within a preset grayscale range to obtain target image data;
[0154] S305: Determine the steady-state type information of each pixel in the target image data according to the target image data, the steady-state type classification threshold, and the preset rule, and perform display control on the color-resistance bistable liquid crystal panel, wherein the preset rule is that if the grayscale value is greater than or equal to M, the steady-state type information is determined to be FC type; if the grayscale value is less than M, the steady-state type information is determined to be P type; or
[0155] S304′: According to the image color-steady-state type relationship table, symmetrically invert the G color grayscale value and the B color grayscale value corresponding to each pixel in the color image data within a preset grayscale range to obtain target image data;
[0156] S305′: Determine the steady-state type information of each pixel in the target image data according to the target image data, the steady-state type classification threshold, and the preset rule, and perform display control on the color-resistance bistable liquid crystal panel, wherein the preset rule is that if the grayscale value is greater than or equal to M, the steady-state type information is determined to be P type; if the grayscale value is less than M, the steady-state type information is determined to be FC type.
[0157] Exemplarily, M is 128 or hexadecimal 80; if the R color grayscale value is 0 (ie less than 80), the steady-state type information is determined to be FC type; if the G color grayscale value and the B color grayscale value are both FF (ie greater than 80), the steady-state type information is determined to be P type.
[0158] Specifically, when the stable-state type information in the display control is P type, the bistable liquid crystal region corresponding to the P type transmits a P state waveform to form a P state, and when the stable-state type information in the display control is FC type, the bistable liquid crystal region corresponding to the FC type transmits an FC state waveform to form an FC state.
