The electronic ink screen is composed of two substrates, electronic ink composed of countless tiny transparent particles is coated on the substrates, the particles are formed by sealing particles with different colors and positive and negative electricity in an internal liquid microcapsule, the charged particles with different colors can move in different directions due to different applied electric fields, and finally different patterns are displayed on the surface of the screen.

The display principle of a conventional LCD screen is that the backlight emits light that needs to pass all the way through the display screen. Based on the display principle of the electronic ink screen, the electronic ink screen is irradiated on the display screen by using ambient light and then refracted to eyes. Compared with an LCD screen, the electronic ink screen has lower refreshing rate, is not easy to feel tired when being read for a long time, and greatly reduces the power consumption.

However, based on the characteristics of low refresh rate and the like brought by the display principle, the electronic ink screen has the following limitations in the function of real-time preview of the screen brushing effect: the electronic ink screen has limited color support display, and when the content to be displayed is different from the color space of the electronic ink screen, a user can hardly know the screen brushing effect directly according to the content to be displayed. Secondly, because the refresh rate of the electronic ink screen is lower, the screen brushing effect is displayed in a mode of refreshing the electronic ink screen, and the timeliness requirement of real-time preview cannot be well matched in speed. Therefore, the existing electronic ink screen display scheme is not configured with a preview function.

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Exemplary application scenarios

Because of the difference between the display principle and the traditional LCD screen, the electronic ink screen brings better reading experience and also has a certain limitation on the function of real-time preview.

Because the electronic ink screen has limited color supported for display, when the content to be displayed is different from the color space of the electronic ink screen, the user cannot easily predict the screen brushing effect directly according to the content to be displayed. In addition, because the refresh rate of the electronic ink screen is lower, the screen brushing effect is displayed in a mode of refreshing the electronic ink screen, and the timeliness requirement of real-time preview cannot be well matched in speed. Therefore, the existing electronic ink screen display scheme is not configured with a preview function.

Exemplary application scenario

In view of this, the embodiments of the present disclosure provide a preview scheme for an electronic ink screen, which uses an interactive device that is interactively connected with the electronic ink screen to perform color processing on a selected display content, so as to complete conversion on a color space, thereby matching the color rendering performance of the electronic ink screen, and enabling the preview effect to be more consistent with the actual display effect. . And displaying preview content by means of the interaction equipment, and realizing a high-timeliness preview function under the condition that the electronic ink screen does not need to be refreshed.

Fig. 1 illustrates an exemplary flowchart of a method 100 for previewing electronic ink screen display content according to some embodiments of the present disclosure, as shown in fig. 1, in step S101, displaying data to be displayed of an electronic ink screen on an interactive device. In this embodiment, the electronic ink screen is interactively connected to the interactive device, where the electronic ink screen may be mounted on a smart device such as a video card. Through the interactive connection, the interactive device can read the data to be displayed of the electronic ink screen, and further, the electronic ink screen can also receive the data and the instructions from the interactive device.

In step S102, in response to a selection instruction fed back by the user, selected display data is determined from the data to be displayed. Taking the interactive device with the touch screen as an example, the interactive device can display the data to be displayed of the electronic ink screen to a user in the form of a picture tiling or numbering list and the like, the user operates on the touch screen, and the touch screen forms a selected instruction in the interactive device by sensing the operation of the user, so that the selected display data is determined.

In step S103, color processing is performed on the selected display data to display preview content corresponding to the selected display data on the interactive device. The color space of an electronic ink screen depends on the color of the particles of the liquid microcapsules within it. Conventional electronic ink screens are typically black and white ink screens, and with the development of electronic ink screens, color ink screens have been capable of displaying three or more colors of content, such as black and white and red color ink screens.

The electronic ink screen color space is limited, and color processing is needed to be performed on the selected display data so as to complete conversion of the color space, so that the display data can be more attached to the actual display effect of the electronic ink screen.

Through color processing, a user can preview the display effect of the selected display data on the electronic ink screen through the interaction equipment, namely, the user can acquire preview content corresponding to the selected display data through the interaction equipment, so that the function of previewing the display effect of the electronic ink screen is realized.

To more accurately accomplish the conversion of color space, some embodiments of the present disclosure provide a color processing method as shown in fig. 2, fig. 2 shows an exemplary flowchart of a color processing method 200 of some embodiments of the present disclosure.

In step S201, first and second two-color image data are generated based on the selected display data, respectively. In some embodiments, the selected display data includes a selected template or a selected picture. In practical application, a user can select a template or a picture to display on the interactive device of the electronic ink screen, and before the electronic ink screen is swiped to display the display data selected by the user, the content can be previewed by the method described in the embodiment.

In order to more precisely complete the conversion of the color space, in step S201, the embodiment first converts the selected display data into a plurality of two-color spaces.

Taking a black-white-red color ink screen as an example, step S201 may convert the selected display data into black-white image data and red-white image data, respectively, through binarization processing, that is, the first dual-color image data and the second dual-color image data described in this embodiment, and then combine the black-white image data and the red-white image data to generate black-white-red image data, thereby completing the conversion of the color space of the selected display data.

In step S202, an exclusive or operation is performed on two pixel values located at the same pixel position in the first bi-color image data and the second bi-color image data, to obtain a pixel value located at the pixel position in the target display data. In the present embodiment, the purpose of step S202 is to merge the data obtained in the two bi-color spaces in step S201 into a color space with a wider color gamut.

Since the first and second bi-color image data are in different color spaces, they may appear in different colors at the same pixel location, e.g., pixels that appear black in black-and-white image data appear white in red-and-white image data. In order to prevent color collision during the merging process, step S202 of the present embodiment performs an exclusive or operation on two pixel values located at the same pixel position in the first bi-color image data and the second bi-color image data, so as to determine a pixel value of each pixel point of the selected display data in the merged color space, that is, a pixel value located at a pixel position in the target display data.

To facilitate understanding of the merging process of color spaces by those skilled in the art, the exclusive-or operation method adopted in some embodiments of the present disclosure is described below with reference to fig. 3, fig. 3 shows an exemplary flowchart of an exclusive-or operation method 300 of some embodiments of the present disclosure, and in step S301, it is determined whether the first pixel value is the same as the second pixel value, as shown in fig. 3. If yes, step S302 is executed, and if no, step S303 is executed. In this embodiment, determining whether the first pixel value is the same as the second pixel value may be understood as determining whether the color that the first pixel position exhibits in the color space of the first two-color image data is the same as the color that it exhibits in the color space of the second two-color image data.

In step S302, the pixel value at the first pixel position in the target display data is updated to the same pixel value. If the color of the first pixel location in the color space of the first bi-color image data is the same as the color it is in the color space of the second bi-color image data, e.g. the pixel location appears white in both black and white image data and red packet image data, it can be unambiguously determined that the first pixel location still appears white in the combined color space. Thus, the pixel value at the first pixel position in the target display data may directly take the original pixel value, i.e. the same pixel value, e.g. (255 ).

In step S303, the pixel value at the first pixel position in the target display data is updated to the conditional filtering value. The condition filtering value is one of a first pixel value and a second pixel value. That is, in the case where the color represented in the color space of the first two-color image data at the first pixel position is different from the color represented in the color space of the second two-color image data, the pixel value of the target display data at the first pixel position needs to be selected from the first pixel value and the second pixel value as the update value.

For example, the first two-color image data is image data having a first color and a second color, the second two-color image data is image data having a first color and a third color, and the condition-filtered value is a pixel value of a pixel point of a non-first color.

Taking black-and-white image data and red-and-white image data as an example, assuming that the first pixel position appears black in the color space of the black-and-white image data and white in the color space of the red-and-white image data, the first pixel position appears black in the color space of the target display data. Assuming that the first pixel position appears white in the color space of black-and-white image data and red in the color space of red-and-white image data, the first pixel position appears red in the color space of the target display data.

Based on this, the conditional screening value of some embodiments of the present disclosure is the pixel value of the non-white pixel point. At this time, the first two-color image data is black-and-white image data, and the second two-color image data is red-and-white image data.

Based on the above description, the exclusive or operation expression for black-and-white image data and red-and-white image data in some embodiments of the present disclosure may be expressed as follows: black +.white=black, red +.white=red, white +.white=white.

It will be appreciated that the above description of the exclusive or operation is directed to one example of a color ink screen displaying three colors, black and white and red. In practical application, the method of combining color spaces through exclusive or operation is also applicable to electronic ink screens of other color spaces, and will not be described in detail here.

According to the method described in connection with fig. 3, the calculation of the pixel value at the first pixel position in the target display data can be completed, so that each pixel position is facilitated, and the exclusive-or operation method is performed for each pixel position, so that the pixel value of each pixel position in the target display data can be obtained.

Returning to fig. 2, in step S203, preview content corresponding to the selected display data is displayed on the interactive device of the electronic ink screen according to the pixel value of each pixel position in the target display data. Because the refresh rate of the electronic ink screen is low, the electronic ink screen is used for displaying the timeliness requirement that the preview function is difficult to match, and based on the consideration, the embodiment uses the interaction equipment of the electronic ink screen for displaying the preview content corresponding to the selected display data.

The interactive device can adopt a display screen with higher refresh rate, such as an LCD display screen, an OLED display screen and the like, and after the color space conversion and merging operations of step S201 and step S202, the color space of the preview content displayed on the interactive device is matched with the color space of the electronic ink screen, so that the display effect on the interactive device can be more fit with the actual display effect of the electronic ink screen.

Some embodiments of the present disclosure divide two different preview modes, e.g., a template mode corresponding to a selected template and a picture mode corresponding to a selected picture, depending on the type of display data selected. The different preview modes differ in the operation of the color conversion, and the two preview modes are described below in connection with fig. 4 to 6, respectively.

First, referring to fig. 4 for a description of the stencil mode, fig. 4 shows an exemplary process diagram of a preview method 400 in the stencil mode according to some embodiments of the present disclosure, as shown in fig. 4, in step S401, a blank bitmap is created with the same resolution as the electronic ink screen. In this embodiment, a blank bitmap with the same resolution as that of the electronic ink screen is created, so that the size of the preview content of the subsequent interactive device can be ensured to adapt to the size of the electronic ink screen, and the problems of deformation and the like can not occur, thereby influencing the preview effect.

In step S402, the selected template is drawn on the blank bitmap to obtain a selected display bitmap. In this embodiment, the selection module may be a template in a template library selected by the user on the interactive device, and the background draws the template content on the blank bitmap according to the template selected by the user, so as to form a selected display bitmap, that is, the selected display data in the bitmap format.

Further, in order to allow customized updating of text information in templates according to scenes and people, some embodiments of the present disclosure provide a method of customized updating of text information.

The method may be applied to a template mode, which is performed prior to step S201, to form customized selected display data. Fig. 5 illustrates an exemplary flowchart of a method 500 of customizing update text information in accordance with some embodiments of the present disclosure, in step S501, loading a selected template. Illustratively, in some embodiments, the template library may be stored in a local storage area, and the selected template is retrieved and loaded offline from the local template library as the selected template is loaded.

In step S502, a custom region of a selected template is located. In this embodiment, the templates in the template library provide text information editing frames, so that text information can be customized according to different scenes or personnel information. In some embodiments, the location information of the customized area of the selected template may be stored in the template library in advance in the form of a tag or the like and associated with the selected template, and after the selected template is loaded in step S501, the customized area of the selected template may be located directly according to the location information of the customized area. In other embodiments, the location of the text message editing box may also be found by a location recognition algorithm, thereby locating the customized area of the selected template.

In step S503, information is edited in the text information edit box of the customizing region to form customized selected display data. In the picture template of the traditional UI design, the text information is fixed, and a great deal of workload is generated if the text information is updated at any time. In this embodiment, the customized updating of the text information can be completed only by editing the information in the text information editing frame of the customized area, so as to form customized selected display data.

Returning again to fig. 4, in step S403, binarization processing is performed on the selected display bitmap to obtain first and second two-color image data, respectively. Taking a color ink screen displaying three colors of black and white as an example, binarization processing is performed on the selected display bitmap to obtain black and white image data and red and white image data. Further, as the color gamut of the color space of the electronic ink screen increases, the number of obtained binarized data correspondingly increases to form more image data in two-color space, and detailed description thereof will not be expanded.

In step S404, an exclusive or operation is performed on two pixel values located at the same pixel position in the first bi-color image data and the second bi-color image data, to obtain a pixel value located at the pixel position in the target display data.

In step S405, according to the pixel value of each pixel position in the target display data, preview content corresponding to the selected display data is displayed on the interactive device of the electronic ink screen.

It should be noted that the content of the steps S404 to S405 is identical to the content of the steps S202 to S203 in the previous embodiment, and will not be described here again.

The preview method in the template mode is described above in connection with fig. 4 and 5, and the preview method in the picture mode is described next in connection with fig. 6.

Fig. 6 illustrates an exemplary process diagram of a preview method 600 in a picture mode in accordance with some embodiments of the present disclosure, as shown in fig. 6, in step S601, a selected picture is converted into a target multi-color picture, such as a three-color picture or a four-color picture, by image processing. In some embodiments, in order to ensure that the preview content matches the size of the electronic ink screen, and avoid the problems of deformation of the preview screen, size mismatch, and the like, in step S601, the selected image may be converted into a selected bitmap with the same resolution as the electronic ink screen through image preprocessing, and then the selected bitmap may be converted into the target multicolor image through image color conversion processing. Image preprocessing illustratively includes image processing such as scaling and/or cropping.

In step S602, binarization processing is performed on the target multicolor picture to obtain first and second two-color image data, respectively. In this embodiment, the implementation manner and purpose of step S602 may refer to the embodiment of fig. 4, which is not described herein.

In step S603, an exclusive or operation is performed on two pixel values located at the same pixel position in the first bi-color image data and the second bi-color image data, to obtain a pixel value located at the pixel position in the target display data.

In step S604, according to the pixel value of each pixel position in the target display data, displaying the preview content corresponding to the selected display data on the interactive device of the electronic ink screen.

It should be noted that the content of the steps S603 to S604 is identical to the content of the steps S202 to S203 in the previous embodiment, and will not be repeated here.

Further, in order to solve the problem that the preview content cannot be loaded in the network-free scenario, the disclosure provides a method for offline loading of data based on the preview method described in any of the foregoing embodiments. In the method, selected display data is stored in a local storage unit.

Based on the above-described method of offline loading of data, in some embodiments of the present disclosure, a method for previewing electronic ink screen display is provided as shown in fig. 7, and fig. 7 shows an exemplary flowchart of a method 700 for previewing electronic ink screen display of other embodiments of the present disclosure.

As shown in fig. 7, in step S701, a selected instruction fed back by a user through an electronic ink screen or an interactive device is acquired. In some embodiments, the manner in which the user feeds back the selection instruction may be as follows, selecting one from a picture list or a template list as the selected display data. In other embodiments, the user may also enter the number of the selected picture or selected template to complete feedback of the selected instruction. In still other embodiments, the user may also import the desired selected display data directly. The feedback mode of the selected instruction is not limited too much in this embodiment.

In addition, the user can feed back the selected instruction through the electronic ink screen, and the electronic ink screen forwards the selected instruction to the interaction equipment in a wired communication mode or a wireless communication mode, or can feed back the selected instruction to the interaction equipment directly.

In step S702, the selected display data is fetched and loaded offline from the local storage unit according to the selected instruction. Since the selected display data is stored in the local storage unit, loading of the selected display data can be completed even in a network-free environment.

In step S703, first and second two-color image data are generated based on the selected display data, respectively.

In step S704, an exclusive or operation is performed on two pixel values located at the same pixel position in the first bi-color image data and the second bi-color image data, to obtain a pixel value located at the pixel position in the target display data.

In step S705, according to the pixel value of each pixel position in the target display data, displaying the preview content corresponding to the selected display data on the interactive device of the electronic ink screen.

It should be noted that, the above steps S703 to S705 are identical to the contents of steps S201 to S203 in the previous embodiment, and are not described herein again.

It should be further noted that the method of offline loading of data can be equally applied to the preview method in the two preview modes described in connection with fig. 4 and 6. For example, the selected templates may be stored in a local template library of the local storage unit, the templates and the rendering content information may be stored offline and loaded offline, and a list of templates may be provided in a software interface of the interactive apparatus, so that the user may not rely on the network environment when selecting the templates. The selected pictures can be stored in a local picture library of the local storage unit, the pictures and the drawing content information are stored offline and loaded offline, and a picture list is provided in a software interface of the interactive device, so that the user can select the pictures independently of the network environment.

In the prior art, when the selected display data is stored in the server, the data is required to be loaded through a network, and the data cannot be acquired in a network-free scene, so that the electronic ink screen cannot be updated. By the scheme described in the embodiment, the problem that the selected display data cannot be loaded when no network exists is solved, and the updating of the electronic ink screen is ensured not to be influenced by the network environment.

Further, in the preview method described in any of the foregoing embodiments, after the first bi-color image data and the second bi-color image data are generated, modulus calculation may be performed on the first bi-color image data and the second bi-color image data, so that binary image data are converted into hexadecimal target data, and then the target data are sent to the storage area of the electronic ink screen through a wired communication manner or a wireless communication manner, so that after receiving a screen brushing instruction, the electronic ink screen finishes screen brushing according to the target data.

Illustratively, the wireless communication manner includes, but is not limited to, NFC communication technology, for example, wireless communication technologies such as ZigBee communication technology, wireless local area network communication technology, and bluetooth communication technology may also be used to implement communication.

In summary, the present disclosure provides a method for previewing display content, the method comprising: displaying data to be displayed of the target device on the interaction device, wherein the target device is in interactive connection with the interaction device; determining selected display data from the data to be displayed in response to a selected instruction fed back by a user; and processing the selected display data to display preview content corresponding to the selected display data on the interactive device.

The method for previewing display content may be for an electronic ink screen or other type of display screen.
