[0044] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0045] The terms "first", "second", and the like in the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, but can optionally include steps or modules not listed, or can optionally include other steps or modules inherent to the process, method, product or device.

[0046] In this document, reference to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a particular embodiment that is independent of or alternative to other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0047] The execution subject of the driving method provided by the embodiments of the present application can be an electronic device integrated with the pixel driving device, and the driving method can be realized in the form of hardware or software.

[0048] The embodiments of the present application provide a driving method for driving a spliced screen, such as Figure 1 As shown in the figure, the spliced screen 100 includes a plurality of first panels 10, a second panel 20 spliced between two adjacent first panels 10, the first panel 10 includes a liquid crystal panel, and the type of the second panel 20 is different from the type of the first panel. The steps of the driving method of the embodiments of the present application will be described in detail.

[0049] In an embodiment, as shown in the figure, Figure 2 The driving method includes but is not limited to the following steps and combinations of the following steps.

[0050] S1, acquiring image information, the image information including first image information and second image information, the first image information being used for the first panel to load to display a first picture.

[0051] The image information can be understood as being used to control the display of the complete image on the video wall 100. Specifically, the video wall 100 may include multiple pixel units, and each pixel unit may include multiple sub-pixels. The image information may include display data corresponding to some or all of the sub-pixel units. For example, when the image information includes display data corresponding to some sub-pixel units, for the sub-pixel units corresponding to the display data not included in the image information, the display data corresponding to the other part of the sub-pixel units can be determined by combining the known display data of the other part of the sub-pixel units with the corresponding algorithm.

[0052] In conjunction with the above discussion, the first image information can be understood as being loaded onto the first panel 10 and used to control the first panel 10 to display the corresponding image (i.e., the first image), and the second image information can be understood as being used to control the second panel 20 to display the corresponding image.

[0053] S2, obtain the second image information from the image information, and correct the second image information to the third image information.

[0054] Specifically, based on the above discussion, the first panel 10 includes a liquid crystal panel, and the second panel 20 is a panel of a different type than the first panel 10. It can be assumed that the second panel 20 has a wider color gamut and displays a brighter image under the same electrical signal compared to the first panel 10. Therefore, it can be assumed that the second panel 20 requires corresponding image information correction compared to the first panel 10 to improve the uniformity of the image displayed on the splicing screen 100. The second panel 20 may include a light-emitting diode (LED) direct-display panel, such as an MLED (Micro LED and Mini LED) direct-display panel. Alternatively, the second panel 20 may include an organic light-emitting diode (OLED) direct-display panel, such as an OLED (Organic Light-Emitting Diode) direct-display panel.

[0055] Among them, such as Figure 1 As shown, multiple first panels 10 can be arranged in a matrix, or along the same or multiple directions, and multiple gaps can be formed between the multiple first panels 10. In this embodiment, the second panel 20 can fill the gaps to display the image at the gap positions. Therefore, the size of the second panel 20 can be considered small. Furthermore, the resolution of the second panel 20 can be smaller than that of the first panel 10. Based on the above analysis, since the size of the second panel 20 is small, its impact on the complete image displayed by the splicing screen 100 is small, or even negligible, which can save the number of pixel units and reduce the cost of the splicing screen 100.

[0056] Specifically, in the embodiment, the second image information is first obtained from the image information, and then the second image information is separately corrected, that is, the second image information is cropped from the image information and then corrected. It can be understood that, compared with the prior art in which more resources (or greater driving force) are directly used to correct the entire image information, the embodiment can only correct the second image information cropped from the image information, and avoid correcting, for example, the first image information that does not need to be corrected, thereby reducing the workload of correction and reducing the waste of driving resources.

[0057] S3, sending the third image information to the second panel to display a third picture, and sending the first image information to the first panel to display a first picture, so that the spliced screen displays a complete picture.

[0058] Specifically, sending the third image information to the second panel 20 to display a third picture and sending the first image information to the first panel 10 to display a first picture can be performed simultaneously or at intervals of a preset time period. The preset time period can satisfy the requirement of avoiding the difference between the presentation time period of the third picture and the presentation time period of the first picture being observed by the human eye, so that the spliced screen 100 displays a complete picture.

[0059] It can be understood that, as known from the above description, the second panel 20 has a greater brightness of the displayed picture under the action of the same electrical signal than the first panel 10, so it can be considered that the corresponding image information needs to be corrected. Therefore, it can be considered that the third image information corrected from the second image information has a smaller brightness when acting on the second panel 20, that is, it can be considered that the brightness of the third picture is smaller than the brightness of the second picture, and the second picture is the picture displayed when the second panel 20 loads the second image information. The embodiment can realize the correction (reduction) of the picture displayed by the second panel 20, that is, it can be considered that the difference between the brightness of the third picture and the brightness of the first picture is small, thereby improving the consistency of the brightness of the picture displayed by the spliced screen 100.

[0060] In an embodiment, the step S2 of obtaining the second image information from the image information includes: obtaining the second image information corresponding to a plurality of address information of the pixel units in the second panel from the image information according to the address information of the pixel units. Specifically, a plurality of pixel units located in different regions (for example, the regions where the first panel 10 or the second panel 20 is located) correspond to an address range. As known from the above description, each pixel unit in the spliced screen 100 can have corresponding address information, and further, the address information of each sub-pixel can be determined according to the address information of each pixel unit and the arrangement mode of the corresponding plurality of sub-pixels.

[0061] The image information can include a corresponding relationship between each sub-pixel in the spliced screen 100 and corresponding address information. It can be understood that, in the embodiment, the address range corresponding to the area where the second panel 20 is located (including each sub-pixel in each pixel unit in the second panel 20) is obtained, and in combination with the above description, the display data corresponding to the address information of each sub-pixel in each pixel unit in the second panel 20 can be obtained from the image information. A plurality of display data corresponding to a plurality of sub-pixels in the second panel 20 can constitute the second image information mentioned above.

[0062] In an embodiment, the second panel includes a plurality of pixel units, and the second image information includes a plurality of to-be-corrected pixel information corresponding to the plurality of pixel units; as Figure 3 In the step S2, the step of correcting the second image information into third image information includes: S201, correcting each to-be-corrected pixel information into corresponding pixel information, and a plurality of pixel information constitutes the third image information; in the step S3, the step of sending the third image information to the second panel to display a third picture includes: S301, sending each pixel information to the corresponding pixel unit in the second panel to display the third picture.

[0063] In combination with the above description, the brightness of the picture (second picture) displayed when the second panel 20 loads the second image information is large, and the plurality of to-be-corrected pixel information corresponding to a plurality of pixel units in the second image information can be understood as including a plurality of to-be-corrected display data corresponding to a plurality of pixels. Specifically, according to the correction rule of each pixel unit, the corresponding to-be-corrected pixel information can be corrected to generate corresponding pixel information (after correction). Further, each pixel unit can include a plurality of sub-pixels, and according to the correction rule of each sub-pixel, the corresponding to-be-corrected display data can be corrected to generate corresponding display data (after correction).

[0064] It can be understood that, in the embodiment, each pixel information (after correction, including a plurality of display data) is loaded into the corresponding pixel unit, and further can be understood as each display data (after correction) is loaded into the corresponding sub-pixel, so that each sub-pixel in the second panel 20 is loaded as display data (after correction), thereby realizing that a plurality of pixel units in the second panel 20 are loaded as a plurality of pixel information (after correction), thereby realizing the reduction of the picture displayed by the second panel 20, so as to close to the brightness of the first picture displayed by the first panel 10, thereby improving the consistency of the brightness of the picture displayed by the spliced screen 100.

[0065] In an embodiment, as Figure 4As shown, each of the pixel units includes a plurality of sub-pixels with different colors, and each of the pixel information includes a plurality of display data corresponding to the plurality of sub-pixels. In step S201, the step of correcting each of the pixel information to be corrected to corresponding pixel information includes, but is not limited to, the following steps and combinations thereof.

[0066] S2011, determining a plurality of binding point parameters corresponding to each of the pixel information to be corrected, each of the binding point parameters including a plurality of sub-parameters corresponding to the plurality of sub-pixels, and the plurality of binding point parameters forming a virtual three-dimensional space, and the pixel information to be corrected being located in the virtual three-dimensional space.

[0067] In combination with the above, each of the pixel information to be corrected can include a plurality of display data to be corrected corresponding to the plurality of sub-pixels in the corresponding pixel unit. Further, for a pixel unit including three sub-pixels (R sub-pixel, G sub-pixel, and B sub-pixel), the pixel information to be corrected can include three display data to be corrected corresponding to the R sub-pixel, the G sub-pixel, and the B sub-pixel, respectively. Each of the display data to be corrected can represent a gray scale value or a stimulus value of the corresponding sub-pixel (R sub-pixel, G sub-pixel, or B sub-pixel), so that each of the pixel information to be corrected (three gray scale values or three stimulus values) can determine the color displayed by the corresponding pixel unit. In the above and hereinafter, the R sub-pixel, the G sub-pixel, and the B sub-pixel are red sub-pixel, green sub-pixel, and blue sub-pixel, respectively. It can be understood that the three sub-pixels are not limited to the R sub-pixel, the G sub-pixel, and the B sub-pixel, but can be other sub-pixels with different colors, such as white sub-pixel, etc.

[0068] Specifically, for each of the display data to be corrected (a, b, or c) in each of the pixel information to be corrected, as shown in FIG. 2B, the step of correcting each of the pixel information to be corrected to corresponding pixel information includes, but is not limited to, the following steps and combinations thereof. Figure 5As shown, a first extended value greater than the display data to be corrected can be set (the first extended values corresponding to the three display data to be corrected can be a1, b1, and c1 respectively, where a1 > a, b1 > b, c1 > c), and a second extended value less than the display data to be corrected can be set (the second extended values corresponding to the three display data to be corrected can be a2, b2, and c2 respectively, where a2 < a, b2 < b, c2 < c). According to the permutations and combinations of the three first extended values (a1, b1, and c1) and the three second extended values (a2, b2, and c2) corresponding to the three sub-pixels, eight combinations ((a1, b1, c1), (a1, b2, c1), (a2, b2, c1), (a2, b1, c1), (a1, b1, c2), (a1, b2, c2), (a2, b2, c2), (a2, b1, c2)) can be formed to be used as eight binding point parameters respectively. Each binding point parameter can include multiple sub-parameters. Here, for example, it can include a first sub-parameter (with a value of a1 or a2), a second sub-parameter (with a value of b1 or b2), and a third sub-parameter (with a value of c1 or c2).

[0069] Further, using the above eight combinations as eight coordinates in a three-dimensional space respectively, a virtual three-dimensional space (a cube or a cuboid) as shown in Figure 5 can be formed. The eight vertices of the cube or cuboid are A, B, C, D, E, F, G, and H respectively. It can be understood that the pixel information to be corrected (for example, including the three display data to be corrected a, b, and c) corresponds to a position (i.e., the coordinate (a, b, c)) in the virtual three-dimensional space (cube or cuboid), which must be located within the cube or cuboid corresponding to the eight vertices A, B, C, D, E, F, G, and H. In particular, when the six values of |a1 - a|, |a2 - a|, |b1 - b|, |b2 - b|, |c1 - c|, and |c2 - c| are equal, that is, the virtual three-dimensional space is a cube, and the position (coordinate) of the pixel information to be corrected (i.e., the corresponding three display data to be corrected) in the virtual three-dimensional space (cube or cuboid) is located at the center of the virtual three-dimensional space (cube).

[0070] S2012, obtain the target color parameter or the target brightness parameter of the pixel unit.

[0071] In an embodiment, at least one of the color parameter and the brightness parameter corresponding to each binding point parameter can be pre-stored. The color parameter and the brightness parameter can respectively represent the color and brightness presented when the corresponding binding point parameter acts on the second panel 20.

[0072] Therefore, in combination with the above description, each pixel unit can have at least one of a color (defined as a target color parameter) and a corresponding brightness parameter (defined as a target brightness parameter) of a picture that should be displayed in theory under the action of each to-be-corrected pixel information (including a plurality of to-be-corrected display data), the target color parameter and the target brightness parameter can be understood as a color and a brightness that a corresponding pixel unit should present in theory, the target color parameter and the target brightness parameter can be a color and a corresponding brightness presented by the first panel 10 under a certain binding point parameter, and the target color parameter and the target brightness parameter can be determined through a human factor experiment or an instrument.

[0073] S2013, selecting a binding point parameter closest to the target color parameter or the target brightness parameter from the plurality of binding point parameters as a reference binding point parameter.

[0074] In step 2013, the "closest" can be defined as: compared with other binding point parameters, the corresponding color or brightness of the reference binding point parameter is closest to the target color parameter or the target brightness parameter. Here, the part of the binding point parameters close to the target color parameter or the target brightness parameter can be determined through a human factor experiment, and then the reference binding point parameter meeting the above description can be determined through further comparison by an instrument. Specifically, the storage can be understood as: selecting a binding point parameter corresponding to a color parameter closest to the target color parameter or a binding point parameter corresponding to a brightness parameter closest to the target brightness parameter from the plurality of binding point parameters as the reference binding point parameter.

[0075] S2014, for each sub-pixel, determining a proportion coefficient of a corresponding color according to a relationship between a color proportion of the corresponding color in the target color parameter and a color proportion of the corresponding color in the reference binding point parameter.

[0076] In step S2014, the "corresponding color" is defined as a color corresponding to the sub-pixel, that is, if for a red sub-pixel (R sub-pixel), the corresponding color is red. The "color proportion" is a gray scale proportion or a stimulus proportion of a certain color; further, the gray scale proportion and the stimulus proportion can be a gray scale value measurement value or a stimulus value measurement value of the color corresponding to all sub-pixels in the pixel. For example, when a certain pixel includes a red sub-pixel (R sub-pixel), a blue sub-pixel (B sub-pixel) and a green sub-pixel (G sub-pixel), the gray scale value measurement value of red of the pixel unit is 100, the gray scale value measurement value of blue of the pixel unit is 50, and the gray scale value measurement value of green of the pixel unit is 150, then the color proportion of red is 100 / (100+50+150) = 1 / 3, the color proportion of blue is 50 / (100+50+150) = 1 / 6, and the color proportion of green is 150 / (100+50+150) = 0.5.

[0077] It should be noted that the "gray scale value measurement" of any color mentioned above, the "stimulus value measurement" of any color can be measured by an instrument, which can be understood as the actual measured gray scale value or stimulus value of each color in the pixel unit; and the "gray scale value" of any color mentioned above, the "stimulus value" of any color can be understood as the theoretically loaded gray scale value or stimulus value of each color in the pixel unit.

[0078] S2015, for each of the sub-pixels, determining the corresponding display data according to the corresponding proportion coefficient and the reference binding point parameter, and the plurality of display data constitutes the corresponding pixel information.

[0079] For example, the color proportion of red in the target color parameter is 0.6, and the color proportion of red in the reference binding point parameter is 0.2, so the proportion coefficient of red is 3 (i.e. 0.6 / 0.2), and assuming that the gray scale value of R in the reference binding point parameter is m, then the corresponding display data of the R sub-pixel in the target color parameter is equal to 3*m. In this example, the proportion is the proportion between the gray scale values (gray scale value measurements).

[0080] In one embodiment, taking the color parameter as an example, at least one color parameter can be selected from a plurality of color parameters corresponding to a plurality of binding point parameters as a reference color parameter. The reference color parameter can be selected arbitrarily, or a color parameter with a higher proximity to the target color parameter can be selected as the reference color parameter. Similarly, the corresponding color proportion of different color sub-pixels in the reference color parameter can be measured by an instrument, as follows:

[0081] For any color sub-pixel in the target color parameter, the corresponding proportion coefficient of the color sub-pixel can be determined according to the relationship between the color proportion of the color sub-pixel in the target color parameter and the color proportion of the color sub-pixel in the selected reference color parameter. Further, according to the proportion relationship of the color sub-pixel (e.g. R sub-pixel), and multiplying the proportion relationship by the value (value a1 or a2) of the sub-parameter (first sub-parameter) corresponding to the color sub-pixel (R sub-pixel) in the binding point parameter of the selected reference color parameter, the value of the corresponding display data (a) to be corrected of the color sub-pixel in the target color parameter can be obtained, as follows:

[0082] For example, the color ratio of R sub-pixel in the target color parameter is measured as 0.6 (the ratio of red among red, green and blue), and the color ratio of R sub-pixel in the reference color is measured as 0.2, then the ratio coefficient of R sub-pixel in the target color parameter relative to R sub-pixel in the reference color is 3 (i.e. 0.6 / 0.2), assuming that the gray scale value of R in the reference color is m, then the corresponding display data of R sub-pixel in the target color parameter is equal to 3*m. In this example, the ratio is the ratio between the gray scale values (gray scale measurement values).

[0083] Similarly, the display data (gray scale value) of other color sub-pixels (G sub-pixel, B sub-pixel) in the target color parameter can also be determined by three-dimensional linear interpolation, and the plurality of display data constitutes the pixel information corresponding to the pixel unit.

[0084] It can be understood that the determination process of the pixel information in the embodiment takes into account the target color parameter or the target brightness parameter, and the target color parameter or the target brightness parameter under the action of the plurality of binding point parameters of the second panel 20 is determined by three-dimensional linear interpolation, and the reliability is high.

[0085] In an embodiment, each of the pixel units at least includes first and second sub-pixels with different colors, each of the pixel information at least includes first sub-pixel information (e.g. display data of R sub-pixel) corresponding to the first sub-pixel and second sub-pixel information (e.g. display data of G sub-pixel) corresponding to the second sub-pixel, and the plurality of binding point parameters at least includes a plurality of first binding point parameters and a plurality of second binding point parameters; wherein, as shown in the figure, Figure 6 The step S201 can include but is not limited to the following steps and combinations of the following steps.

[0086] S2016, determining a plurality of binding point parameters corresponding to each of the pixel information to be corrected, the plurality of binding point parameters at least includes a plurality of first binding point parameters and a plurality of second binding point parameters, and the plurality of binding point parameters constitutes a virtual three-dimensional space, and the pixel information to be corrected is located in the virtual three-dimensional space;

[0087] S2017, obtaining a plurality of first binding point values corresponding to the plurality of first binding point parameters, and performing three-dimensional linear interpolation on the plurality of first binding point parameters and the corresponding plurality of first binding point values to generate the first sub-pixel information in the corresponding pixel information;

[0088] S2018, obtaining a plurality of second binding point values corresponding to the plurality of second binding point parameters, and performing three-dimensional linear interpolation on the plurality of second binding point parameters and the corresponding plurality of second binding point values to generate the second sub-pixel information in the corresponding pixel information.

[0089] Specifically, as can be known from the above, when the binding point parameter acts on the second panel 20, the displayed picture has at least one of the corresponding color parameter and the brightness parameter, and any one of the first binding point value and the second binding point value can be understood as including at least one of the color parameter and the brightness parameter corresponding to the corresponding binding point parameter. As can be known from the above, each binding point value determined by the human factor experiment or the instrument can be pre-stored in the spliced screen. It should be noted that each binding point parameter has a corresponding binding point value (for example, each first binding point parameter corresponds to a first binding point value, and each second binding point parameter corresponds to a second binding point value). When the number of binding point parameters (the arrangement combination of the three first extension values (a1, b1 and c1) and the three second extension values (a2, b2 and c2)) is large, if the pre-stored multiple binding point values (at least including the first binding point value and the second binding point value) are acquired at one time, a large enough memory (for example, a random access memory (RAM)) is required for storage.

[0090] For example, the first sub-parameter in the multiple first binding point parameters in the embodiment can not be the same, for example, the first sub-parameter in at least one binding point parameter is equal to the first extension value (a1) of the corresponding display data to be corrected, and the first sub-parameter in at least another binding point parameter is equal to the second extension value (a2) of the corresponding display data to be corrected, that is, at least two binding point parameters with different first sub-parameter values are selected as the multiple first binding point parameters. Therefore, it can be considered that the first binding point values corresponding to the at least two first binding point parameters can present color difference or brightness difference for the first sub-pixel, and at least in combination with the proportion coefficient of the first sub-pixel color or brightness in the target color parameter, the first sub-pixel information corresponding to the first sub-pixel in the pixel information is determined. For details, reference can be made to the related description of step S2012 above.

[0091] Similarly, the second sub-parameter in the multiple second binding point parameters in the embodiment can not be the same, and also in order to at least combine the proportion coefficient of the second sub-pixel color or brightness in the target color parameter to determine the second sub-pixel information corresponding to the second sub-pixel in the pixel information.

[0092] Specifically, in the embodiment, each time, part of the binding point values can be acquired, and after acquiring the part of the binding point values (the plurality of first binding point values or the plurality of second binding point values), the part of the sub-pixel information is generated by combining the part of the binding point parameters, the corresponding relationship of the plurality of binding point values, and at least one of the target color parameter or the target brightness parameter through three-dimensional linear interpolation. In this way, part of the binding point values can be acquired in time, and the part of the sub-pixel information can be determined.

[0093] It can be understood that, compared with acquiring all the binding point parameters and corresponding all the binding point values at one time to determine the pixel information, the embodiment does not need to acquire all the binding point parameters and corresponding all the binding point values at one time to determine the pixel information, but acquires part of the binding point values in time and stores the part of the binding point values in the memory, so that after the corresponding sub-pixel information is determined, the corresponding part of the binding point values can be released, so as to acquire another part of the binding point values. The required memory is smaller, and the memory resources are saved.
