[0044] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0045] It should be clear that the described embodiments are only 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 ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0047] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0049] It should be understood that although the terms first, second, etc. may be used to describe parts, leads, etc. in the embodiments of the present application, these should not be limited to these terms. These terms are only used to distinguish display panels, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first color display panel may also be referred to as the second color display panel, and similarly, the second color display panel may also be referred to as the first color display panel. The applicant of this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0050] Figure 1 A schematic diagram of a display module provided in an embodiment of the present application.

[0051] like Figure 1 As shown, the display module 01 includes a plurality of display panels 10, and the plurality of display panels 10 correspond one-to-one to a plurality of projection screens, and the projection screen is a screen projected from the display screen of the display panel 10 onto the target projection surface 20. When the display module 01 displays the image to be displayed, the image to be displayed is decomposed into different parts, and the different parts are respectively displayed in the plurality of display panels 10 included in the display module 01. In other words, the plurality of display panels 10 of the display module 01 respectively display different parts of the image to be displayed, and the plurality of display panels 10 project the displayed parts onto the target projection surface 20, so as to display the image to be displayed on the target projection surface 20.

[0052] like Figure 1As shown, the display module 01 includes a red display panel 10R for displaying a red image, a green display panel 10G for displaying a green image, and a blue display panel 10B for displaying a blue image, wherein the pixels included in the red display panel 10R can emit red light, the pixels included in the green display panel 10G can emit green light, and the pixels included in the blue display panel 10B can emit blue light. The image to be displayed can be realized by controlling the brightness of pixels of different colors, that is, the image to be displayed is divided into a red part, a blue part, and a green part, and the red display panel 10R is used to display the red part to present a red display picture, the green display panel 10G is used to display the green part to present a green display picture, and the blue display panel 10B is used to display the blue part to present a blue display picture. The red display picture, the green display picture, and the blue display picture are projected onto the target projection surface 20 respectively to obtain a red projection picture, a green projection picture, and a blue projection picture, and the red projection picture, the green projection picture, and the blue projection picture are mixed on the target projection surface 20 to display the image to be displayed.

[0053] The display module 01 provided in the embodiment of the present application may be a projection module such as a 3LCD projector, or may be a display module 01 for realizing holographic display.

[0054] Take the display module 01 as a 3LCD projector as an example, please refer to Figure 1 , the 3LCD projector contains three independent LCD display panels 10, namely the red display panel 10R, the green display panel 10G and the blue display panel 10B, and each LCD display panel 10 contains a number of pixels. The white light emitted by the light source L0 is decomposed into three colors of light, namely red light LR, green light LG and blue light LB, by the beam splitter L1, and the red light LR is incident on the red display panel 10R, the green light LG is incident on the green display panel 10G, and the blue light LB is incident on the blue display panel 10B through the reflector L2. The pixels on each LCD display panel 10 can be precisely controlled to allow different amounts of light to pass through, thereby modulating the light. The monochrome image of each LCD display panel 10 passes through a special prism L3 and aggregates to form a full-color image. The image synthesized by the prism L3 is processed and magnified by the lens group L4, and finally presented on the target projection to form a viewable image.

[0055] It should be noted that the display module 01 related to the embodiment of the present application may include a target projection surface 20. For example, the display module 01 related to the embodiment of the present application may include a target projection surface 20 such as a screen. In addition, the display module 01 related to the embodiment of the present application may not include the target projection surface 20. The user may select a suitable target projection surface 20 according to their own needs. For example, a white wall may be used as the target projection surface 20.

[0056] It should also be noted that when the chromaticity of the image to be displayed needs to be obtained by mixing red light, green light and blue light, the image data corresponding to any pixel in the image to be displayed includes the red grayscale value, green grayscale value and blue grayscale value corresponding to the pixel. Then the above-mentioned division of the image to be displayed into a red part, a blue part and a green part means respectively obtaining the red grayscale value, green grayscale value and blue grayscale value of each pixel in the image to be displayed. After the data voltage corresponding to the red grayscale value is transmitted to the red display panel 10R, the red display panel 10R displays a red display screen, the data voltage corresponding to the green grayscale value is transmitted to the green display panel 10G, the green display panel 10G displays a green display screen, and the data voltage corresponding to the blue grayscale value is transmitted to the blue display panel 10B, the blue display panel 10B displays a blue display screen.

[0057] It can be understood that a pixel of an image can include sub-pixels of three different colors: red, green, and blue, and the luminous brightness corresponding to the three different colors of the sub-images respectively determines the brightness and chromaticity of the pixel. However, since the red display panel 10R only includes units that can emit red light, the light-emitting units in the red display panel 10R are referred to as panel pixels. It can be understood that the red light emitted by a panel pixel in the red display panel 10R actually corresponds to the red grayscale corresponding to a pixel in the image to be displayed, that is, the red sub-pixel of a pixel in the image to be displayed. Accordingly, the light-emitting units in the green display panel 10G are referred to as panel pixels, and the light-emitting units in the blue display panel 10B are referred to as panel pixels.

[0058] Since the smallest controllable unit of the display image presented by the display panel 10 corresponds to the pixel included in the display panel 10, and the projection image is actually obtained by projecting the display image onto the target projection surface 20, the light-emitting unit corresponding to the pixel of the display panel 10 in the projection image is called a projection pixel.

[0059] In order to ensure that a clear image to be displayed can be displayed on the target projection surface 20, each projection screen should be projected at a preset position, otherwise the image to be displayed on the target projection surface 20 will be blurred. When the position of any display panel 10 changes, the position of the corresponding projection screen on the target projection surface 20 will also change. Therefore, in order to ensure that a clear image to be displayed can be displayed on the target projection surface 20, each display panel 10 should be at a preset position.

[0060] Figure 2 A schematic diagram of a projection screen of an image to be displayed on a target projection surface related to an embodiment of the present application.

[0061] For example, the image corresponding to the first column of pixels of the image to be displayed is displayed on the first column of panel pixels of the red display panel 10R, the first column of panel pixels of the green display panel 10G, and the first row and first column of panel pixels of the blue display panel 10B. Assuming that the position of the red display panel 10R changes relative to the preset position, Figure 2 As shown, the first column of pixels of the red projection image, the first column of pixels of the green projection image, and the first column of pixels of the blue projection image are not aligned on the target projection surface 20, resulting in the inability to perform normal color mixing of the red projection image, the green projection image, and the blue projection image to obtain the first column of the image to be displayed IM. Therefore, a blurred image appears on the target projection surface 20.

[0062] It should be noted that Figure 2 The multiple squares arranged in a matrix in the image IM to be displayed in the target projection surface 20 represent multiple pixels in the image IM to be displayed, and the multiple squares arranged in a matrix in each projection screen 200 on the target projection surface 20 represent projection pixels. In addition, different filling patterns of different squares represent different grayscale values ​​of these squares.

[0063] Figure 3 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0064] Based on the above problems, the present application embodiment provides a method for aligning the screen of the display module 01, such as Figure 3 As shown, the method includes:

[0065] S1: Based on the projection picture features and the initial image data of the image to be displayed, a plurality of target display data groups are obtained.

[0066] The projection picture feature includes information about the overlap and / or misalignment of projection pixels of each projection picture 200 with other projection pictures 200, that is, information about the overlap and / or misalignment of projection pixels in each projection picture 200 with projection pixels in other projection pictures 200. Assuming that the target projection surface 20 includes N projection pictures 200, the projection picture feature includes information about the overlap and / or misalignment of projection pixels respectively included in the N projection pictures 200.

[0067] It should be noted that the multiple projection pixels used to display the same pixel in the image IM to be displayed can overlap with each other to achieve color mixing, or can be separated by a preset distance to achieve color mixing. For example, when the multiple projection pixels used to display the same pixel in the image IM to be displayed overlap with each other to achieve color mixing, the different projection pixels used to display the same pixel in the image IM to be displayed coincide with each other, and they are considered to be overlapped; the different projection pixels used to display the same pixel in the image IM to be displayed are separated, and they are considered to be misaligned. For example, when the multiple projection pixels used to display the same pixel in the image IM to be displayed are separated by a preset distance to achieve color mixing, the distance between the different projection pixels used to display the same pixel in the image IM to be displayed is less than or equal to the preset distance, and they are considered to overlap; the distance between the different projection pixels used to display the same pixel in the image IM to be displayed is greater than the preset distance, and they are considered to be misaligned. The embodiment of the present application is explained by taking the example that the multiple projection pixels used to display the same pixel in the image IM to be displayed need to overlap with each other to achieve color mixing.

[0068] The projection pixels in the projection screen 200 that overlap with other projection screens 200 are called overlapping projection pixels, and the projection pixels in the projection screen 200 that do not overlap with at least one of the other projection screens 200 are called misaligned projection pixels. The projection screen feature includes information about overlapping projection pixels and misaligned projection pixels in each projection screen 200.

[0069] For example, combined with Figure 1 and Figure 2 , the target projection surface 20 includes a red projection screen 20R, a green projection screen 20G, and a blue projection screen 20B. Then the projection screen features may include information such as pixel columns and pixel rows overlapped by the red projection screen 20R and the green projection screen 20G, pixel columns and pixel rows overlapped by the red projection screen 20R and the blue projection screen 20B, and pixel columns and pixel rows overlapped by the green projection screen 20G and the blue projection screen 20B; and / or, the projection screen features may include information such as pixel columns and pixel rows misaligned by the red projection screen 20R and the green projection screen 20G, pixel columns and pixel rows misaligned by the red projection screen 20R and the blue projection screen 20B, and pixel columns and pixel rows misaligned by the green projection screen 20G and the blue projection screen 20B. The following is an example in which pixel columns of projection screens 200 of different colors overlap and misalign, and pixel rows of projection screens 200 of different colors overlap.

[0070] by Figure 2For example, according to the characteristics of the projection screen, it can be concluded that the 2nd to 8th pixel columns in the red projection screen 20R overlap with the 1st to 7th pixel columns of the green projection screen 20G and the 1st to 7th pixel columns of the blue projection screen 20B, and the 1st pixel column in the red projection screen 20R does not overlap with the green projection screen 20G and the blue projection screen 20B, and the 8th pixel column in the green projection screen 20G and the 8th pixel column in the blue projection screen 20B do not overlap with the red projection screen 20R. Then, the projection pixels in the 2nd to 8th pixel columns in the red projection screen 20R, the projection pixels in the 1st to 7th pixel columns in the green projection screen 20G, and the projection pixels in the 1st to 7th pixel columns in the blue projection screen 20B are all overlapping projection pixels 201, and the projection pixels in the 1st pixel column in the red projection screen 20R, the projection pixels in the 8th pixel column in the green projection screen 20G, and the projection pixels in the 8th pixel column in the blue projection screen 20B are all staggered projection pixels 202.

[0071] The multiple target display data groups are respectively used to be transmitted to the corresponding display panels 10, that is, different display panels 10 receive target data in different target data groups respectively. The target data in the target data group can be a data voltage in the form of an analog signal, or can be grayscale value data in the form of a digital signal. The target data group can be obtained from the initial image data, and obtaining the target data group from the initial image data at least includes obtaining the display data to be received by each display panel 10 in the initial image data.

[0072] Each target display data group includes overlapping display data and staggered display data. The overlapping display data respectively included in different target display data groups correspond to the same picture in the image to be displayed IM, that is, the overlapping display data in each target display data group is obtained according to the initial image data corresponding to the same part in the image to be displayed IM; and the staggered display data in each target display data group is obtained according to the initial image data corresponding to another part in the image to be displayed IM.

[0073] In addition, when acquiring multiple target display data groups, which data in the initial image data are used to obtain the overlapping display data and which data in the initial image data are used to obtain the offset display data need to be determined based on the projection picture characteristics.

[0074] For example, Figure 2For example, the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B all have 7 columns of pixel columns composed of overlapping projection pixels 201 and 1 column of pixel columns composed of staggered projection pixels 202. The overlapping display data corresponding to each display panel 10 can be obtained based on the image data of 7 columns of adjacent pixels in the initial image data, and the staggered display data corresponding to each display panel 10 can be obtained based on the image data of the other column of pixels in the initial image data.

[0075] S2: controlling the overlapping data in the target display data set to be transmitted to the overlapping panel pixels 101 in the corresponding display panel 10 , and controlling the misaligned display data in the target display data set to be transmitted to the misaligned panel pixels 102 in the corresponding display panel 10 .

[0076] The overlapping panel pixels 101 in the display panel 10 correspond to the overlapping projection pixels 201 in the projection screen 200 that overlap with other projection screens 200, and the staggered panel pixels 102 in the display panel 10 correspond to the staggered projection pixels 202 in the projection screen 200 that are staggered with at least one other projection screen 200. Wherein, any projection screen 200 is obtained by projecting the display screen of a display panel 10 onto the target projection surface 20, therefore, when the projection screen 200 includes the overlapping projection pixels 201, part of the panel pixels in the display panel 10 corresponding to the projection screen 200 is defined as the overlapping panel pixels 101, and the overlapping panel pixels 101 are displayed and projected to obtain the overlapping projection pixels 201 in the projection screen 200; when the projection screen 200 includes the staggered projection pixels 202, part of the panel pixels in the display panel 10 corresponding to the projection screen 200 is defined as the staggered panel pixels 102, and the staggered panel pixels 102 are displayed and projected to obtain the staggered projection pixels 202 in the projection screen 200.

[0077] Figure 4 A schematic diagram of a projection screen of an image to be displayed on a target projection surface related to an embodiment of the present application.

[0078] For example, Figure 4As shown, the projection pixels in the 2nd to 8th pixel columns in the red projection screen 20R, the projection pixels in the 1st to 7th pixel columns in the green projection screen 20G, and the projection pixels in the 1st to 7th pixel columns in the blue projection screen 20B are all overlapping projection pixels 201, and the projection pixels in the 1st pixel column in the red projection screen 20R, the projection pixels in the 8th pixel column in the green projection screen 20G, and the projection pixels in the 8th pixel column in the blue projection screen 20B are all staggered projection pixels 202. Assuming that the first to eighth pixel columns in the red projection screen 20R correspond to the first to eighth pixel columns in the red display panel 10R, the first to eighth pixel columns in the green projection screen 20G correspond to the first to eighth pixel columns in the green display panel 10G, and the first to eighth pixel columns in the blue projection screen 20B correspond to the first to eighth pixel columns in the blue display panel 10B. Accordingly, the first pixel columns in the red display panel 10R correspond to the first to eighth pixel columns in the green display panel 10G. The panel pixels in the 2nd to 8th pixel columns, the panel pixels in the 1st to 7th pixel columns in the green display panel 10G, and the panel pixels in the 1st to 7th pixel columns in the blue display panel 10B are all overlapping panel pixels 101, and the panel pixels in the 1st pixel column in the red display panel 10R, the panel pixels in the 8th pixel column in the green display panel 10G, and the panel pixels in the 8th pixel column in the blue display panel 10B are all staggered panel pixels 102.

[0079] The overlapping data in the target display data group is transmitted to the overlapping panel pixels 101 in the corresponding display panel 10, so that the overlapping panel pixels 101 in each display panel 10 can display the same part of the image IM to be displayed. Therefore, the overlapping projection pixels 201 in each projection screen 200 can display the same part of the image IM to be displayed, thus solving the problem of blurring of the image IM to be displayed when it is displayed on the target projection surface 20.

[0080] For example, Figure 4As shown, the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B all have 7 columns of pixel columns composed of overlapping projection pixels 201 and 1 column of pixel columns composed of staggered projection pixels 202. The overlapping display data respectively received by the overlapping panel pixels 101 in the red display panel 10R, the green display panel 10G and the blue display panel 10B are all obtained according to the initial image data corresponding to the same 7 columns of adjacent pixels I M1-I M7 in the image IM to be displayed. Then, the overlapping panel pixels 101 in the red display panel 10R, the green display panel 10G and the blue display panel 10B are used to display the pictures corresponding to the 7 adjacent columns of pixels in the image IM to be displayed. Therefore, the overlapping projection pixels 201 in the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B are used to display the pictures corresponding to the 7 adjacent columns of adjacent pixels in the image IM to be displayed.

[0081] The misaligned display data may be related to the image IM to be displayed, or may be unrelated to the image IM to be displayed. For example, no matter how the image IM to be displayed changes, the misaligned display data received by different misaligned panel pixels 102 in the red display panel 10R may be the same, the misaligned display data received by different misaligned panel pixels 102 in the green display panel 10G may be the same, and the misaligned display data received by different misaligned panel pixels 102 in the blue display panel 10B may be the same.

[0082] In some embodiments, the staggered display data respectively received by different display panels 10 can make the staggered panel pixels 102 in the display panel 10 all appear black.

[0083] In addition, the staggered display data received by different display panels 10 can make the staggered panel pixels 102 in the display panel 10 present corresponding colors. For example, the staggered display data received by the red display panel 10R makes the staggered panel pixels 102 in the display panel 10 present red, the staggered display data received by the green display panel 10G makes the staggered panel pixels 102 in the display panel 10 present green, and the staggered display data received by the blue display panel 10B makes the staggered panel pixels 102 in the display panel 10 present blue. At this time, the brightness of the staggered panel pixel 102 can be the same as or similar to the brightness of the adjacent overlapping panel pixel 101. Figure 4The staggered display data received by the red display panel 10R makes the leftmost staggered panel pixel 102 in the red display panel 10R present red with the same brightness as the second column panel pixel on the left (overlapping panel pixel 101), the staggered display data received by the green display panel 10G makes the rightmost staggered panel pixel 102 in the green display panel 10G present green with the same brightness as the second column panel pixel on the right (overlapping panel pixel 101), and the staggered display data received by the blue display panel 10B makes the rightmost staggered panel pixel 102 in the blue display panel 10B present blue with the same brightness as the second column panel pixel on the right (overlapping panel pixel 101).

[0084] The signal processor included in the display module 01 processes the image signal it receives, such as decoding, scaling, color correction, etc., wherein the image data obtained after the image signal is decoded by the signal processor may be the initial image data described in the embodiment of the present application.

[0085] Figure 5 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0086] In one embodiment of the present application, Figure 5 As shown, S1: based on the projection picture feature and the initial image data of the image IM to be displayed, a plurality of target display data groups are obtained, including:

[0087] S11: Based on the projection picture features, the initial image data of the image to be displayed IM is reconstructed to obtain a target image data set.

[0088] Figure 6 A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0089] like Figure 6 As shown, the pixel grayscale included in the image data can be regarded as data in matrix form, and reconstructing the initial image data D0 to obtain the target image data group D1 can be understood as reconstructing the pixel grayscale matrix corresponding to the initial image data D0, including adjusting the coordinates and / or grayscale values ​​corresponding to the pixel grayscale of the initial image data D0, and finally obtaining the target image data group D1. The target image data group D1 includes overlapping image data and staggered image data, wherein the picture corresponding to the overlapping image data can be displayed by the overlapping panel pixels 101 in each display panel 10 and presented by the overlapping projection pixels 201 of the projection screen 200, and the picture corresponding to the staggered image data can be displayed by the staggered panel pixels 102 in each display panel 10 and presented by the staggered projection pixels 202 of the projection screen 200.

[0090] It should be noted that the initial image data D0 can be regarded as including a plurality of initial image data groups, wherein the initial image data in each initial image data group respectively corresponds to the image data to be displayed by different display panels 10. For example, the display module 01 includes a red display panel 10R, a green display panel 10G and a blue display panel 10B, then the initial image data D0 can be regarded as including a red initial image data group D0R, a green initial image data group D0G and a blue initial image data group D0B, wherein the initial image data in the red initial image data group D0R corresponds to a red picture, the initial image data in the green initial image data group D0G corresponds to a green picture, and the initial image data in the blue initial image data group D0B corresponds to a blue picture.

[0091] Among them, the target image data group D1 can correspond to the target display data group one by one. For example, when the display module 01 includes three display panels 10 and the three receive display data in different target display data groups, that is, the three target data groups correspond to the three display panels 10 one by one, then the three target image data groups D1 can be obtained from the initial image data D0, and the three target image data groups D1 correspond to the three target display data groups respectively. Specifically, when the three display panels included in the display module 01 are the red display panel 10R, the green display panel 10G and the blue display panel 10B, respectively, the red target image data group D1R, the green target image data group D1G and the blue target image data group D1B are obtained from the initial image data D0, and the display data in the target display data groups obtained from the red target image data group D1R, the green target image data group D1G and the blue target image data group D1B are respectively transmitted to the red display panel 10R, the green display panel 10G and the blue display panel 10B.

[0092] Since the picture corresponding to the overlapping image data in the target image data group D1 needs to be displayed through the overlapping panel pixels 101 and displayed through the overlapping projection pixels 201, which image data in the image data will be used as overlapping image data and which image data in the image data will be used as staggered image data can be determined based on the characteristics of the projection picture.

[0093] S12: Convert the overlapping image data of the target image data set D1 into overlapping display data, and convert the misaligned image data in the target image data set D1 into misaligned display data, to obtain a target display data set.

[0094] The target display data group is obtained by converting the image data in the target image data group D1 into display data recognizable by the display panel 10, and then the overlapping image data in the target image data group D1 can be converted into overlapping display data, and the staggered image data can be converted into staggered display data. Among them, the display data in the target display data group includes overlapping display data, and the overlapping display data is transmitted to the overlapping panel pixels 101 in the display panel 10 to drive the overlapping panel pixels 101 to display and display through the overlapping projection pixels 201 of the projection screen 200. The overlapping image data in the target image data group D1 corresponds to the overlapping display data; accordingly, the staggered image data in the target image data group D1 corresponds to the staggered display data.

[0095] After the target image data group D1 obtained by processing the image signal by the signal processor is transmitted to the driver IC of the display module 01, the driver IC of the display module 01 converts the image data in the target image data group D1 into display data that can be recognized by the display panel 10. That is, in the screen alignment method provided in this embodiment, the driver IC of the display module 01 converts the target image data group D1 into a target display data group.

[0096] In this embodiment, before the image data is converted into display data, the initial image data D0 signal is processed according to the projection screen characteristics to obtain the target image data group D1, wherein the image data in the target image data group D1 includes the overlapping image data corresponding to the overlapping projection pixel 201 in the display panel 10 and the misaligned image data corresponding to the misaligned projection pixel 202 in the display panel 10. When converting the image data into display data, there is no need to consider the projection screen characteristics. Therefore, the driver IC in the display module 01 can maintain the original computing power.

[0097] Figure 7 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0098] In a technical solution corresponding to this embodiment, as Figure 7 As shown, S11: based on the projection picture feature, the initial image data D0 of the image to be displayed IM is reconstructed to obtain a target image data group D1, including:

[0099] S111: Based on the projection picture feature, determine a reference image data group and a to-be-adjusted image data group from a plurality of initial image data D0.

[0100] The reference image data set includes overlapping image data.

[0101] In the present application, since different parts of the image IM to be displayed are respectively displayed in different display panels 10 of the display module 01, the initial image data D0 can be regarded as consisting of a plurality of initial image data D0 groups, wherein the pictures corresponding to the image data in different initial image data D0 groups are respectively displayed in different display panels 10. Among them, the reference image data group and the image data group to be adjusted can be regarded as different initial image data D0 groups.

[0102] Based on the projection picture characteristics, overlapping image data and staggered image data can be determined in the reference image data group. The overlapping image data in the reference image data group can be converted into overlapping display data to be received by the display panel 10 corresponding to the reference image data group, and the corresponding picture can be displayed using the overlapping projection pixels 201. The overlapping image data in the staggered image data group can be converted into staggered display data to be received by the display panel 10 corresponding to the reference image data group, and the corresponding picture can be displayed using the staggered projection pixels 202.

[0103] Among them, the coordinates of the pixel grayscale represented by the image data included in the reference image data group may not be adjusted, and the coordinates of the overlapping image data in the reference image data group correspond to the overlapping panel pixels 101 in the display panel 10, so that the overlapping display data obtained by converting the overlapping image data can be transmitted to the corresponding overlapping panel pixels 101 and control the luminous brightness of the overlapping panel pixels 101; the coordinates of the staggered image data in the reference image data group correspond to the staggered panel pixels 102 in the display panel 10, so that the staggered display data obtained by converting the staggered image data can be transmitted to the corresponding staggered panel pixels 102 and control the luminous brightness of the staggered panel pixels 102.

[0104] S112: Selecting a first type of image data to be adjusted from the image data group to be adjusted.

[0105] The first type of image data to be adjusted and the overlapping image data in the reference image data group correspond to the same picture in the image to be displayed IM.

[0106] Therefore, the first type of image data to be adjusted can be selected from the initial image data group D0 according to the overlapping image data in the reference image data group, wherein the first type of image data to be adjusted and the overlapping image data in the reference image data group correspond to the same frame in the image IM to be displayed.

[0107] The technical solution of the present application can be understood as selecting a partial picture from the image to be displayed IM and displaying the partial picture using the overlapping projection pixels 201 of each projection picture 200, and finally clearly displaying the partial picture on the target projection surface 20. Therefore, the first type of image data to be adjusted selected from the image data group to be adjusted can be understood as the image data based on which the display panel 10 corresponding to the image data group to be adjusted displays the partial picture.

[0108] S113: changing the coordinates of the first type of image data to be adjusted to obtain overlapping image data.

[0109] The coordinates of the first type of image data to be adjusted are changed to obtain overlapping image data. The coordinates of the first type of image data to be adjusted are changed to correspond to the coordinates of the overlapping panel pixels 101 in the display panel 10, so that the overlapping image data obtained from the first type of image data to be adjusted is converted into overlapping display data, and the overlapping display data can be transmitted to the corresponding overlapping panel pixels 101 to control the luminous brightness of the overlapping panel pixels 101.

[0110] Through the above method, it is only necessary to select the first type of image data to be adjusted in the partial initial image data D0 group and change the coordinates of these first type of image data to be adjusted to obtain the overlapping image data, and there is no need to change the coordinates of the image data in the reference image data group. Therefore, it will not pose too much challenge to the computing power of the signal processor.

[0111] For example, combined with Figure 2 and Figure 6 , when the projection image features include Figure 2 When the projection pixel information is shown, Figure 6As shown, the initial image data D0 can be divided into a red initial image data group D0R, a green initial image data group D0G and a blue initial image data group D0B, and the red initial image data group D0R is used as a reference image data group, and the green initial image data group D0G and the blue initial image data group D0B are used as image data groups to be adjusted. Assuming that the image data from the 1st column to the 8th column in the red initial image data group D0R respectively correspond to the panel pixels from the 1st column to the 8th column in the red display panel 10R and the projection pixels from the 1st column to the 8th column in the red projection screen 20R, since the projection pixels from the 2nd column to the 8th column in the red projection screen 20R are overlapping projection pixels 201, the image data from the 2nd column to the 8th column in the red initial image data group D0R are overlapping image data. Assuming that the pixels in the first to eighth columns of the image to be displayed IM correspond to the image data in the first to eighth columns of each initial image data group D0, it means that the overlapping image data in the reference image data group corresponds to the picture of the pixels in the second to eighth columns of the image to be displayed IM, therefore, the image data in the second to eighth columns of the green initial image data group D0G and the blue initial image data group D0B are taken as the first type of image data to be adjusted; since the projection pixels in the first to seventh columns of the green projection picture 20G and the blue projection picture 20B are the overlapping projection pixels 201, therefore, the coordinates of the first type of image data to be adjusted (the image data in the second to eighth columns) in the green initial image data group D0G and the blue initial image data group D0B are changed to the first to seventh columns. The overlapping image data obtained from the first type of image data to be adjusted also corresponds to the picture of the pixels in the second to eighth columns of the image to be displayed IM, and is displayed by the overlapping projection pixels 201 in the green projection picture 20G and the blue projection picture 20B. At this time, the overlapping projection pixels in the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B on the target projection surface 20 are used to display the screens corresponding to the pixels of the 2nd to 8th columns of the image IM to be displayed, and a clear projection screen 200 is presented on the target projection surface 20.

[0112] Figure 8 A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0113] For example, combined with Figure 2 and Figure 8 , when the projection image features include Figure 2 When the projection pixel information is shown, Figure 8As shown, the initial image data D0 can be divided into a red initial image data group D0R, a green initial image data group D0G and a blue initial image data group D0B, and the green initial image data group D0G and the blue initial image data group D0B are both used as reference image data groups, and the red initial image data group D0R is used as the image data group to be adjusted. Assuming that the image data from the first to the eighth columns in the green initial image data group D0 and the blue initial image data group D0B correspond to the first to the eighth columns of panel pixels in the green display panel 10G and the blue display panel 10B, respectively, and correspond to the first to the eighth columns of projection pixels in the green projection screen 20G and the blue projection screen 20B, respectively, since the first to the seventh columns of projection pixels in the green projection screen 20G and the blue projection screen 20B are overlapping projection pixels 201, the image data from the first to the seventh columns in the green initial image data group D0G are overlapping image data, and the image data from the first to the seventh columns in the blue initial image data group D0B are overlapping image data. Assuming that the pixels in the first to eighth columns of the image to be displayed IM correspond to the image data in the first to eighth columns of each initial image data group D0, it means that the overlapping image data in the reference image data group corresponds to the picture of the pixels in the first to seventh columns of the image to be displayed IM, therefore, the image data in the first to seventh columns of the red initial image data group D0R are taken as the first type of image data to be adjusted; since the projection pixels in the second to eighth columns of the red projection picture 20R are the overlapping projection pixels 201, therefore, the coordinates of the first type of image data to be adjusted (the image data in the first to seventh columns) in the red initial image data group D0R are changed to the second to eighth columns. The overlapping image data obtained from the first type of image data to be adjusted also corresponds to the picture of the pixels in the first to seventh columns of the image to be displayed IM, and is displayed by the overlapping projection pixels 201 in the red projection picture 20R. At this time, the overlapping projection pixels in the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B on the target projection surface 20 are used to display the screens corresponding to the pixels of the 1st to 7th columns of the image IM to be displayed, and a clear projection screen 200 is presented on the target projection surface 20.

[0114] Fig. 9 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0115] In one implementation, Fig. 9 As shown, S11: based on the projection picture feature, reconstructing the initial image data D0 of the image to be displayed IM to obtain the target image data group D1 may also include:

[0116] S114: Select the second type of image data to be adjusted from the image data group to be adjusted.

[0117] The second type of image data to be adjusted is other image data in the image data group to be adjusted except the first type of image data to be adjusted. Figure 6 As shown, the green initial image data group D0G and the blue initial image data group D0B are the image data groups to be adjusted, and the image data from the 2nd to the 8th columns in the green initial image data group D0G and the blue initial image data group D0B are all the first type of image data to be adjusted, and the image data from the 1st column in the green initial image data group D0G and the blue initial image data group D0B are the second type of image data to be adjusted; for example, Figure 8 As shown, the red initial image data group D0R is the image data group to be adjusted, the image data from the 2nd to the 8th columns in the red initial image data group D0R are all the first type of image data to be adjusted, and the image data from the 1st column in the red initial image data group D0R are the second type of image data to be adjusted.

[0118] S115: changing the grayscale value of the second type of image data to be adjusted to the first grayscale value and changing the coordinates of the second type of image data to be adjusted to obtain misaligned image data.

[0119] S116: Changing the grayscale value of the misaligned image data included in the reference image data set to a first grayscale value.

[0120] The coordinates of the second type of image data to be adjusted are changed to obtain the offset image data, and the coordinates of the second type of image data to be adjusted correspond to the coordinates of the offset panel pixels 102 in the display panel 10 after the change, so that the offset image data obtained from the second type of image data to be adjusted can be converted to obtain the offset display data, and the offset display data can be transmitted to the corresponding offset panel pixels 102 to control the luminous brightness of the offset panel pixels 102. In addition, the grayscale value of the offset image data in the parameter image data group is changed to the first grayscale value, so that the offset panel pixels 102 in the display panel 10 can all display the first grayscale value and the offset projection pixels 202 on the target projection surface 20 can all display the first grayscale value.

[0121] For example, Figure 6As shown, when the image data of the 2nd to 8th columns in the green initial image data group D0G and the blue initial image data group D0B are all the first type of image data and the image data of the 1st column in the green initial image data group D0G and the blue initial image data group D0B are the second type of image data, the grayscale value of the image data of the 1st column is changed to the first grayscale value; in addition, since the projection pixels of the 8th column in the green projection screen 20G and the blue projection screen 20B are the offset projection pixels 202, the coordinates of the second type of image data to be adjusted (the image data of the 1st column) in the green initial image data group D0G and the blue initial image data group D0B are changed to the 8th column. The offset image data obtained from the second type of image data to be adjusted is displayed by the offset projection pixels 202 in the green projection screen 20G and the blue projection screen 20B that do not overlap with the red projection screen 20R.

[0122] For example, Figure 8 As shown, when the image data in the first to seventh columns of the red initial image data group D0R are all the first type of image data and the image data in the eighth column of the red initial image data group D0R are the second type of image data, the grayscale values ​​of the image data in the eighth column are all changed to the first grayscale value; in addition, since the projection pixels in the first column of the red projection screen 20R are the offset projection pixels 202, the coordinates of the second type of image data to be adjusted (the eighth column of image data) in the red initial image data group D0R are changed to the first column. The offset image data obtained from the second type of image data to be adjusted is displayed by the offset projection pixels 202 in the red projection screen 20R that do not overlap with the green projection screen 20G and the blue projection screen 20B.

[0123] The first grayscale value may be grayscale 0. At this time, the staggered panel pixels 102 in each display panel 10 receive display data corresponding to grayscale 0, and the staggered panel pixels 102 in the display panel 10 display black. Correspondingly, the staggered projection pixels 202 in each projection screen 200 display black.

[0124] The first grayscale value may also be grayscale 255. In addition, the first grayscale value may also be other grayscales, for example, the first grayscale value of the staggered panel pixel 102 is the same as the grayscale value of the adjacent overlapping panel pixel 101 .

[0125] In one implementation, only the coordinates of the second type of image data to be adjusted may be changed to obtain the misaligned image data, without processing the grayscale values ​​of the second type of image data to be adjusted and the grayscale values ​​of the misaligned image data included in the reference image data group.

[0126] In some embodiments of the present application, the display module 01 includes a first color display panel 10, a second color display panel 10, and a third color display panel 10. The projection of the picture displayed by the first color display panel 10 on the target projection surface 20 is a first color projection picture 20G, the projection of the picture displayed by the second color display panel 10 on the target projection surface 20 is a second color projection picture 200, and the projection of the picture displayed by the third color display panel 10 on the target projection surface 20 is a third color projection picture 200. For example, among the first color display panel 10, the second color display panel 10, and the third color display panel 10, one may be a red display panel 10R, one may be a green display panel 10G, and one may be a blue display panel 10B; correspondingly, one of the first color projection picture 20G, the second color projection picture 200, and the third color projection picture 200 is a red projection picture 20R, one may be a green projection picture 20G, and one may be a blue projection picture 20B. The following description will be made by taking as an example that the first color display panel 10 is a green display panel 10G, the second color display panel 10 is a red display panel 10R, and the third color display panel 10 is a blue display panel 10B.

[0127] In a technical solution corresponding to these embodiments, in a first direction parallel to the target projection surface 20, the second color projection picture 20R is offset by n projection pixels relative to the first color projection picture 20G and the third color projection picture 20B toward the first projection direction, that is, the second color projection picture 20R is offset by n projection pixels relative to the first color projection picture 20G and the third color projection picture 20B toward the first projection direction. Figure 2 As shown, the first direction is the row direction and the first offset direction is the left direction, and n is 1, that is, the red projection picture 20R is offset to the left by a distance of one column of projection pixels relative to the blue projection picture 20B and the green projection picture 20G.

[0128] Fig.10 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0129] In one implementation, Fig.10 As shown, S111: based on the projection picture feature, a reference image data group and a to-be-adjusted image data group are determined from a plurality of initial image data D0, including:

[0130] S111a: Based on the projection picture characteristics, the initial image data D0 corresponding to the second color projection picture 20R is determined as the reference image data set, and the initial image data D0 corresponding to the first color projection picture 20G and the third color projection picture 20B are determined as the image data sets to be adjusted.

[0131] That is, the multiple image data corresponding to the second color display panel 10R in the initial image data D0 are used as the reference image data group, and the multiple image data corresponding to the first color display panel 10G and the third color display panel 10B in the initial image data D0 are used as the image data group to be adjusted.

[0132] In this implementation, according to the projection picture characteristics, it is possible to determine which projection pictures 200 are completely overlapped, and the initial image data D0 corresponding to these projection pictures 200 are determined as the image data group to be adjusted.

[0133] For example, Figure 8 As shown, the red projection screen 20R is offset to the left by a distance of one column of projection pixels relative to the blue projection screen 20B and the green projection screen 20G, and the initial image data group D0 corresponding to the red projection screen 20R is determined as the reference image data group, and the initial image data group D0 corresponding to the green projection screen 20G and the initial image data group D0 corresponding to the blue projection screen 20B are determined as the image data group to be adjusted.

[0134] Fig.11 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0135] In one implementation, Fig.11 As shown, S111: based on the projection picture feature, a reference image data group and a to-be-adjusted image data group are determined from a plurality of initial image data D0, including:

[0136] S111b: Based on the projection picture characteristics, the initial image data D0 corresponding to the second color projection picture 20R is determined as the image data group to be adjusted, and the initial image data D0 corresponding to the first color projection picture 20G and the third color projection picture 20B are determined as the reference image data group. That is, the multiple image data corresponding to the second color display panel 10R in the initial image data D0 are used as the image data group to be adjusted, and the multiple image data corresponding to the first color display panel 10G and the third color display panel 10B in the initial image data D0 are used as the reference image data group.

[0137] In this implementation, based on the projection screen features, it is possible to determine which completely overlapping different projection screens 200 are, and determine the initial image data D0 corresponding to these projection screens 200 as reference image data groups, which can reduce the workload of obtaining multiple target image data groups D1.

[0138] For example, Figure 7As shown, the red projection screen 20R is offset to the left by a distance of one column of projection pixels relative to the blue projection screen 20B and the green projection screen 20G, the initial image data group D0 corresponding to the green projection screen 20G and the initial image data group D0 corresponding to the blue projection screen 20B are determined as reference image data groups, and the initial image data group D0 corresponding to the red projection screen 20R is determined as the image data group to be adjusted.

[0139] Fig.12 A schematic diagram of a projection screen of an image to be displayed on a target projection surface related to an embodiment of the present application.

[0140] In a technical solution corresponding to these embodiments, in a first direction parallel to the target projection surface 20, the second color projection picture 20R is offset by n projection pixels relative to the first color projection picture 20G toward the first projection orientation, and the third color projection picture 20B is offset by m projection pixels relative to the second color projection picture 20R toward the first projection orientation, that is, relative to the second color projection picture 20R, the first color projection picture 20G and the third color projection picture 20B are offset to different sides of the second color projection picture 20R in the first direction. Among them, n and m may be equal or unequal.

[0141] For example, Fig.12As shown, the first direction is the row direction, the first offset direction is the left direction, and the second offset direction is the right direction. The green projection screen 20G is offset to the left by a distance of one column of projection pixels relative to the red projection screen 20R, and the blue projection screen 20B is offset to the right by a distance of one column of projection pixels relative to the red projection screen 20R. Assume that the pixels in the first to eighth columns of the image to be displayed IM correspond to the image data in the first to eighth columns of each initial image data D0 group, and the image data in the first to eighth columns of each initial image data D0 group correspond to the panel pixels in the first to eighth columns of the display panel 10. Then the projection pixels from the 2nd to the 7th column in the red projection screen 20R are overlapping projection pixels 201, and correspondingly, the panel pixels from the 2nd to the 7th column in the red display panel 10R are overlapping panel pixels 101, and the image data from the 2nd to the 7th column in the red initial image data group D0R are overlapping image data; the projection pixels from the 1st column and the 8th column in the red projection screen 20R are staggered projection pixels 202, and correspondingly, the panel pixels from the 1st column and the 8th column in the red display panel 10R are staggered panel pixels 102, and the image data from the 1st column and the 8th column in the red initial image data group D0R are staggered image data. The projection pixels in the 3rd to 8th columns in the green projection screen 20G are overlapping projection pixels 201, and correspondingly, the panel pixels in the 3rd to 8th columns in the green display panel 10G are overlapping panel pixels 101, and the image data in the 3rd to 8th columns in the green initial image data group D0G are overlapping image data; the projection pixels in the 1st and 2nd columns in the green projection screen 20G are staggered projection pixels 202, and correspondingly, the panel pixels in the 1st and 2nd columns in the green display panel 10G are staggered panel pixels 102, and the image data in the 1st and 2nd columns in the green initial image data group D0G are staggered image data. The projection pixels in the 1st to 6th columns in the blue projection screen 20B are overlapping projection pixels 201, and correspondingly, the panel pixels in the 1st to 6th columns in the blue display panel 10B are overlapping panel pixels 101, and the image data in the 1st to 6th columns in the blue initial image data group D0B are overlapping image data; the projection pixels in the 7th and 8th columns in the blue projection screen 20B are staggered projection pixels 202, and correspondingly, the panel pixels in the 7th and 8th columns in the blue display panel 10B are staggered panel pixels 102, and the image data in the 7th and 8th columns in the blue initial image data group D0B are staggered image data.

[0142] The initial image data D0 can be divided into a green initial image data group D0G, a green initial image data group D0G and a blue initial image data group D0B, and the red initial image data group D0R is used as a reference image data group, and the green initial image data group D0G and the blue initial image data group D0B are both used as image data groups to be adjusted.

[0143] In one implementation, Fig.10 As shown, S111: based on the projection picture feature, a reference image data group and a to-be-adjusted image data group are determined from a plurality of initial image data D0, including:

[0144] S111a: Based on the projection picture characteristics, the initial image data D0 corresponding to the second color projection picture 20R is determined as the reference image data group, and the initial image data D0 corresponding to the first color projection picture 20G and the third color projection picture 20B are determined as the image data group to be adjusted. That is, the multiple image data corresponding to the second color display panel 10R in the initial image data D0 are used as the reference image data group, and the multiple image data corresponding to the first color display panel 10G and the third color display panel 10B in the initial image data D0 are used as the image data group to be adjusted.

[0145] In this implementation, based on the projection screen features, a projection screen 200 that is located in the middle can be determined among multiple projection screens 200. The projection pixels contained in this projection screen 200 overlap with the projection pixels of other projection screens 200, and the initial image data D0 corresponding to each of the projection screens 200 is determined as a reference image data group.

[0146] Fig.13 A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0147] For example, combined with Fig.12 and Fig.13 , when the projection image features include Fig.12 When the projection pixel information shown is obtained, the initial image data group D0 corresponding to the red projection screen 20R is determined as the reference image data group, and the initial image data group D0 corresponding to the green projection screen 20G and the initial image data group D0 corresponding to the blue projection screen 20B are determined as the image data group to be adjusted. Since the projection pixels from the 2nd to 7th columns in the red projection screen 20R are overlapping projection pixels 201, the image data from the 2nd to 7th columns in the red initial image data group D0R are overlapping image data, that is, the overlapping image data in the reference image data group corresponds to the picture of the pixels from the 2nd to 7th columns of the image IM to be displayed. Therefore, Fig.13As shown, the image data from the 2nd to 7th columns in the green initial image data group D0G and the blue initial image data group D0B are used as the first type of image data to be adjusted. Since the projection pixels from the 3rd to 8th columns in the green projection screen 20G are the overlapping projection pixels 201 and the projection pixels from the 1st to 6th columns in the blue projection pixels are the overlapping projection pixels 201, the coordinates of the first type of image data to be adjusted (the image data from the 2nd to 7th columns) in the green initial image data group D0G are changed to the 3rd to 8th columns, and the coordinates of the first type of image data to be adjusted (the image data from the 2nd to 7th columns) in the blue initial image data group D0B are changed to the 1st to 6th columns. The overlapping image data obtained from the first type of image data to be adjusted in the green initial image data group D0G and the overlapping image data obtained from the first type of image data to be adjusted in the blue initial image data group D0B both correspond to the pictures of the pixels in the 2nd to 7th columns in the image IM to be displayed, and are displayed by the overlapping projection pixels 201 in the green projection screen 20G and the blue projection screen 20B. At this time, the overlapping projection pixels in the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B on the target projection surface 20 are used to display the pictures corresponding to the pixels in the 2nd to 7th columns of the image IM to be displayed, and a clear projection screen 200 is presented on the target projection surface 20.

[0149] In one implementation, Fig.14 As shown, S111: based on the projection picture feature, a reference image data group and a to-be-adjusted image data group are determined from a plurality of initial image data D0, including:

[0150] S111d: Based on the projection picture characteristics, the initial image data D0 corresponding to the first color projection picture 20G is determined as the reference image data group, and the initial image data D0 corresponding to the second color projection picture 20R and the third color projection picture 20B are determined as the image data group to be adjusted. That is, the multiple image data corresponding to the first color display panel 10G in the initial image data D0 are used as the reference image data group, and the multiple image data corresponding to the second color display panel 10R and the third color display panel 10B in the initial image data D0 are used as the image data group to be adjusted.

[0151] In this implementation, according to the projection picture characteristics, a projection picture 200 that is biased to one side can be determined from multiple projection pictures 200, and the initial image data D0 corresponding to the projection picture 200 can be determined as a reference image data group.

[0152] Fig.15A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0153] For example, combined with Fig.12 and Fig.15 , when the projection image features include Fig.12 When the projection pixel information shown is displayed, the initial image data group D0 corresponding to the green projection screen 20G is determined as the reference image data group, and the initial image data group D0 corresponding to the red projection screen 20R and the initial image data group D0 corresponding to the blue projection screen 20B are determined as the image data group to be adjusted. Since the projection pixels in the 3rd to 8th columns in the green projection screen 20G are overlapping projection pixels 201, the image data in the 3rd to 8th columns in the green initial image data group D0G are overlapping image data, that is, the overlapping image data in the reference image data group corresponds to the picture of the pixels in the 3rd to 8th columns of the image IM to be displayed. Therefore, Fig.16 As shown, the image data from the 3rd to the 8th columns in the red initial image data group D0R and the blue initial image data group D0B are used as the first type of image data to be adjusted. Since the projection pixels from the 2nd to the 7th columns in the red projection screen 20R are the overlapping projection pixels 201 and the projection pixels from the 1st to the 6th columns in the blue projection pixels are the overlapping projection pixels 201, the coordinates of the first type of image data to be adjusted (the image data from the 3rd to the 8th columns) in the red initial image data group D0R are changed to the 2nd to the 7th columns, and the coordinates of the first type of image data to be adjusted (the image data from the 3rd to the 8th columns) in the blue initial image data group D0B are changed to the 1st to the 6th columns. The overlapping image data obtained from the first type of image data to be adjusted in the red initial image data group D0R and the overlapping image data obtained from the first type of image data to be adjusted in the blue initial image data group D0B both correspond to the pictures of the pixels in the 3rd to 8th columns in the image IM to be displayed, and are displayed by the overlapping projection pixels 201 in the red projection screen 20R and the blue projection screen 20B. At this time, the overlapping projection pixels in the red projection screen 20R, the green projection screen 20G and the blue projection screen 20B on the target projection surface 20 are used to display the pictures corresponding to the pixels in the 3rd to 8th columns of the image IM to be displayed, and a clear projection screen 200 is presented on the target projection surface 20.

[0155] In one implementation, Fig.16 As shown, S111: based on the projection picture feature, determining a reference image data group and a to-be-adjusted image data group from a plurality of initial image data D0, including:

[0156] S111e: Based on the projection picture feature, the initial image data D0 corresponding to the third color projection picture 20B is determined as the reference image data group, and the initial image data D0 corresponding to the first color projection picture 20G and the second color projection picture 20R are determined as the image data group to be adjusted. That is, the multiple image data corresponding to the third color display panel 10B in the initial image data D0 are used as the reference image data group, and the multiple image data corresponding to the first color display panel 10G and the second color display panel 10R in the initial image data D0 are used as the image data group to be adjusted.

[0157] In this implementation, according to the projection picture characteristics, a projection picture 200 that is biased to one side can be determined from multiple projection pictures 200, and the initial image data D0 corresponding to the projection picture 200 can be determined as a reference image data group.

[0158] Fig.17 A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0159] For example, combined with Fig.12 and Fig.17 , when the projection image features include Fig.12 When the projection pixel information shown is displayed, the initial image data group D0 corresponding to the blue projection screen 20B is determined as the reference image data group, and the initial image data group D0 corresponding to the red projection screen 20R and the initial image data group D0 corresponding to the green projection screen 20G are determined as the image data group to be adjusted. Since the projection pixels in the 1st to 6th columns of the blue projection screen 20B are overlapping projection pixels 201, the image data in the 1st to 6th columns of the blue initial image data group D0B are overlapping image data, that is, the overlapping image data in the reference image data group corresponds to the picture of the pixels in the 1st to 6th columns of the image IM to be displayed. Therefore, Fig.18As shown, the image data from the first to the sixth columns in the red initial image data group D0R and the green initial image data group D0G are used as the first type of image data to be adjusted. Since the projection pixels from the second to the seventh columns in the red projection screen 20R are the overlapping projection pixels 201 and the projection pixels from the third to the eighth columns in the green projection pixels are the overlapping projection pixels 201, the coordinates of the first type of image data to be adjusted (the image data from the first to the sixth columns) in the red initial image data group D0R are changed to the second to the seventh columns, and the coordinates of the first type of image data to be adjusted (the image data from the first to the sixth columns) in the green initial image data group D0G are changed to the third to the eighth columns. The overlapping image data obtained from the first type of image data to be adjusted in the red initial image data group D0R and the overlapping image data obtained from the first type of image data to be adjusted in the green initial image data group D0G both correspond to the pictures of the pixels in the 3rd to 8th columns in the image IM to be displayed, and are displayed by the overlapping projection pixels 201 in the red projection screen 20R and the green projection screen 20G. At this time, the overlapping projection pixels in the red projection screen 20R, the blue projection screen 20B and the green projection screen 20G on the target projection surface 20 are used to display the pictures corresponding to the pixels in the 3rd to 8th columns of the image IM to be displayed, and a clear projection screen 200 is presented on the target projection surface 20.

[0160] Fig.18 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0161] In one embodiment of the present application, Fig.18 As shown, S11: based on the projection picture feature, the initial image data D0 of the image to be displayed IM is reconstructed to obtain a target image data group D1, including:

[0162] S111 ′: for each initial image data group, select the first type of image data to be adjusted and the second type of image data to be adjusted from the initial image data group D0 .

[0163] The initial image data D0 can be regarded as being composed of a plurality of initial image data groups, wherein the pictures corresponding to the image data in different initial image data groups are respectively displayed in different display panels 10. The first type of image data to be adjusted respectively included in different initial image data groups corresponds to the same picture in the image to be displayed IM, and the second type of image data to be adjusted is other image data in the initial image data group except the first type of image data to be adjusted; the second type of image data to be adjusted in the same initial image data group is located on both sides of the first type of image data to be adjusted.

[0164] Fig.19 A schematic diagram of a projection screen of an image to be displayed on a target projection surface related to an embodiment of the present application, Fig. 20A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0165] For example, Fig. 20 As shown, the initial image data D0 can be divided into a green initial image data group D0G, a red initial image data group D0R and a blue initial image data group D0B, and the green projection screen 20G is offset to the left by 2 columns of projection pixels relative to the red projection screen 20R, and the blue projection screen 20B is offset to the right by 1 column of projection pixels relative to the red projection screen 20R. Then each projection screen 200 includes 5 columns of projection overlapping pixels 201, and each display panel 10 includes 5 columns of overlapping panel pixels 101. Therefore, the initial image data group can include 5 columns of overlapping image data, wherein the 5 columns of overlapping image data can be used as the first type of image data to be adjusted. Fig. 20 As shown, the 3rd to 7th columns of image data representing the same picture are selected from the 8 columns of initial image data respectively included in each initial image data group as the first type of image data to be adjusted. In addition, the 1st, 2nd and 8th columns of image data among the 8 columns of initial image data respectively included in each initial image data group are the second type of image data to be adjusted and are located on both sides of the first type of image data to be adjusted.

[0166] It should be noted that the second type of image data to be adjusted being located on both sides of the first type of image data to be adjusted means that the display screens corresponding to the second type of image data to be adjusted are located on both sides of the display screens corresponding to the first type of image data to be adjusted.

[0167] S112 ′: based on the projection picture feature, the coordinates of the first type of image data to be adjusted are changed to obtain overlapping image data.

[0168] If the first type of image data to be adjusted is located in the middle of the second type of image data to be adjusted, then the display screen corresponding to the first type of image data to be adjusted is located at a position away from the edge of the image to be displayed. If the first type of image data to be adjusted is changed to overlapping image data, then when the image to be displayed is displayed on the target projection surface, the screen displayed by the overlapping projection pixels 201 of each projection screen 200 is a position away from the edge of the image to be displayed. This avoids the loss of a large area of ​​the image to be displayed, and ensures that the image to be displayed is relatively complete when displayed on the target projection surface 20.

[0169] For example, combined with Fig.19 and Fig. 20, the projection pixels from the 4th to the 8th columns in the green projection screen 20G are overlapping projection pixels 201, the projection pixels from the 2nd to the 6th columns in the red projection screen 20R are overlapping projection pixels 201, and the projection pixels from the 1st to the 5th columns in the blue projection screen 20B are overlapping projection pixels 201, then the coordinates of the image data from the 3rd to the 7th columns in the green initial image data group D0G are changed to the 4th to the 8th columns to obtain green overlapping image data, the coordinates of the image data from the 3rd to the 7th columns in the red initial image data group D0R are changed to the 2nd to the 6th columns to obtain red overlapping image data, and the coordinates of the image data from the 3rd to the 7th columns in the blue initial image data group D0B are changed to the 1st to the 5th columns to obtain blue overlapping image data.

[0170] Fig.21 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0171] In one embodiment of the present application, Fig.21 As shown, S11: based on the projection picture feature, the initial image data D0 of the image to be displayed IM is reconstructed to obtain the target image data group D1, and also includes:

[0172] S113 ′: changing the grayscale value of the second type of image data to be adjusted to the first grayscale value and changing the coordinates of the second type of image data to be adjusted to obtain misaligned image data.

[0173] For example, combined with Fig.19 and Fig. 20 , the projection pixels in the 1st to 3rd columns in the green projection screen 20G are staggered projection pixels 202, the projection pixels in the 1st and 7th to 8th columns in the red projection screen 20R are staggered projection pixels 202, and the projection pixels in the 6th to 8th columns in the blue projection screen 20B are staggered projection pixels 202, then the coordinates of the 1st, 2nd and 8th columns of image data in the green initial image data group D0G are changed to the 1st to 3rd columns and the grayscale value is changed to 0 grayscale to obtain green staggered image data, the coordinates of the 1st, 2nd and 8th columns of image data in the red initial image data group D0R are changed to the 1st column and the 7th to 8th columns and the grayscale value is changed to 0 grayscale to obtain red staggered image data, and the coordinates of the 1st, 2nd and 8th columns of image data in the blue initial image data group D0B are changed to the 6th to 8th columns and the grayscale value is changed to 0 grayscale to obtain blue staggered image data.

[0174] The first grayscale value may also be grayscale 255. In addition, the first grayscale value may also be other grayscales, for example, the first grayscale value of the staggered panel pixel 102 is the same as the grayscale value of the adjacent overlapping panel pixel 101 .

[0175] Fig. 22A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0176] In one embodiment of the present application, Fig. 22 As shown, S11: based on the projection picture feature, the initial image data D0 of the image to be displayed IM is reconstructed to obtain a target image data group D1, including:

[0177] S111”: based on the projection picture feature, compressing the initial image data of the image to be displayed to obtain overlapping image data.

[0178] The initial image data D0 can be regarded as being composed of a plurality of initial image data groups, wherein the images corresponding to the image data in different initial image data groups are respectively displayed in different display panels 10. The initial image data of the image to be displayed is compressed to obtain overlapping image data, which can be understood as compressing each initial image data group to obtain overlapping image data groups corresponding to each initial image data group, and the data in different overlapping image data groups correspond to overlapping panel pixels 101 in different display panels 10, and also correspond to overlapping projection pixels 201 in different projection images.

[0179] In the embodiment of the present application, compressing the initial image data of the image to be displayed can be regarded as reducing the resolution of the image to be displayed; and compressing the initial image data to obtain the overlapping image data can be regarded as the image to be displayed after the resolution is reduced, which is displayed by the overlapping panel pixels 101 in different display panels 10 and can be presented by the overlapping projection pixels 201 in each projection screen. In this embodiment, although the resolution of the image to be displayed displayed by the display panel is lower than the initial resolution of the image to be displayed, the display panel can display a relatively complete image to be displayed, and a relatively complete image to be displayed can be presented on the target projection surface.

[0180] In addition, S11: based on the projection picture feature, reconstructing the initial image data D0 of the image to be displayed IM to obtain the target image data set D1 may also include:

[0181] S112”: inserting the misaligned image data; so that the target image data group includes the overlapping image data and the misaligned image data.

[0182] Fig.23 A schematic diagram of the relationship between initial image data and a display screen of a display panel related to an embodiment of the present application.

[0183] For example, Fig.23As shown, the initial image data D0 can be divided into a green initial image data group D0G, a red initial image data group D0R and a blue initial image data group D0B. Fig.23 , the green projection screen 20G is offset to the left by 2 columns of projection pixels relative to the red projection screen 20R, and the blue projection screen 20B is offset to the right by 1 column of projection pixels relative to the red projection screen 20R. Then each projection screen 200 includes 5 columns of projection overlapping pixels 201, and each display panel 10 includes 5 columns of overlapping panel pixels 101. Therefore, the 8 columns of image data in the initial image data group can be compressed to obtain 5 columns of overlapping image data in the target image data group D1.

[0184] The original image data can be compressed as follows Fig.23 As shown, a method of extracting pixel columns and / or pixel rows is adopted; other methods of reducing the image resolution may also be used, and this application does not limit this.

[0185] Fig.24 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0186] In one embodiment of the present application, Fig.24 As shown, S1: based on the projection picture feature and the initial image data D0 of the image IM to be displayed, a plurality of target display data groups are obtained, including:

[0187] S11 ′: converting the initial image data D0 of the image IM to be displayed into an initial display data group.

[0188] The initial display data group includes initial overlapping display data and initial staggered display data. The initial overlapping display data is converted from the overlapping image data in the initial image data D0, and the initial staggered display data is converted from the staggered image data in the initial image data D0. The overlapping image data in different initial image data D0 correspond to the same picture in the image IM to be displayed.

[0189] S12 ′: Based on the projection picture feature, the storage address of the initial overlapping display data in at least part of the initial display data set is changed, and the storage address of the initial misaligned display data in at least part of the initial display data set is changed to obtain a target display data set.

[0190] By changing the storage address of the initial overlapping display data in at least part of the initial display data group, the initial overlapping display data can be transmitted to the overlapping panel pixels 101 in the display panel; by changing the storage address of the initial misaligned display data in at least part of the initial display data group, the initial misaligned display data can be transmitted to the misaligned panel pixels 102 in the display panel.

[0191] In this embodiment, in order to enable the overlapping panel pixels 101 in different display panels 10 to display the same part of the image to be displayed IM, after receiving the image data and obtaining the display data according to the image data, the driver IC stores the overlapping display data and the overlapping panel pixels 101 in correspondence. That is, in this embodiment, the core steps of the display module screen alignment method can be completed by the driver IC.

[0192] Assume that the projection image features are as follows Figure 4 As shown, the target display data group corresponding to the red display panel is taken as an example for explanation.

[0193] In the prior art, after obtaining the initial display data group corresponding to the red display panel according to the initial image data D0 of the image to be displayed IM, the initial display data in the initial display data group is stored in the corresponding preset storage position. Among them, the initial display data corresponding to the first left column of the image to be displayed IM is stored in the position so that the initial display data will be transmitted to the first left column of the display panel, so that the first left column of the image to be displayed IM is displayed in the first left column of the display panel; the initial display data corresponding to the second left column of the image to be displayed IM is stored in the position so that the initial display data will be transmitted to the second left column of the display panel, so that the second left column of the image to be displayed IM is displayed...

[0194] In the present embodiment, after the initial display data group corresponding to the red display panel is obtained according to the initial image data D0 of the image IM to be displayed, the initial display data in the initial display data group is stored in the changed storage position. Among them, the initial display data corresponding to the first column on the left of the image IM to be displayed is stored in a position so that these display data can be transmitted to the second column on the left of the display panel to display the first column on the left of the image IM to be displayed, and the initial display data corresponding to the third column on the left of the image IM to be displayed is stored in a position so that these display data can be transmitted to the third column on the left of the display panel to display the second column on the left of the image IM to be displayed... Finally, as Figure 4 As shown, the panel pixels in the 2nd to 8th columns of the red display panel 10R are used to display the pictures in the 1st to 7th columns of the image IM to be displayed.

[0195] It can be seen that the purpose of changing the storage address of the initial overlapping display data in the initial display data group is to control the display data corresponding to the same screen in the image to be displayed IM to be transmitted to the overlapping panel pixels in the display panel. Therefore, the purpose of changing the storage address of the initial overlapping display data in the initial display data group is the same as that of changing the coordinates of the first type of image data to be adjusted. Therefore, which initial display data is used as the initial overlapping display data and how to change the storage address of the initial overlapping display data to correspond to the overlapping panel pixels 101 can refer to the concept of selecting the first type of image data to be adjusted and changing the coordinates of the first type of image data to be adjusted. No further details will be given here.

[0196] In addition, which initial display data is used as the initial misaligned display data and how to change the storage address and data value of the initial misaligned display data to correspond to the misaligned panel pixel 201 can refer to the concept of selecting the second type of image data to be adjusted and changing the coordinates and grayscale value of the second type of image data to be adjusted. No further details will be given here.

[0197] Fig.25 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0198] In one embodiment of the present application, Fig.25 As shown, S11′: converting the initial image data D0 of the image IM to be displayed into an initial display data group, including:

[0199] S11 - 1 ′: obtaining a data voltage of initial overlapping display data according to the grayscale value of the overlapping image data in the initial image data D0 ;

[0200] S11 - 2 ′: according to the offset image data in the initial image data D0 , the data voltage of the initial offset display data is determined as the first data voltage.

[0201] In the technical solution, the display data may be a data voltage. Then the storage address of the initial overlapping display data in at least part of the initial display data group is changed and the storage address of the initial offset display data in at least part of the initial display data group is changed, that is, the storage address of the data voltage is changed.

[0202] In addition, the first data voltage can make the offset panel pixel 101 display black. Or the first data voltage can make the offset panel pixel 101

[0211] After all the display panels 10 in the display module 01 are fully lit, the display images displayed by each display panel 10 are displayed as projection images 200 on the target projection surface 20, and all the overlapping and misaligned projection pixels of each projection image 200 are presented. Therefore, the image of each projection image 200 on the target projection image 200 can be obtained through one image acquisition. In one implementation, each display panel 10 can be fully lit at the same time, so that all the overlapping and misaligned projection pixels of each projection image 200 are presented at the same time.

[0212] The image of each projection screen 200 collected after each display panel 10 is fully lit is analyzed to obtain the projection screen features. For example, each pixel of the projection screen 200 is divided from the collected image of the projection screen 200, and the overlapping and misaligned projection pixel information of each projection screen 200 is obtained based on the color change in the image of the projection screen 200.

[0213] by Fig.19 Taking the green display panel 10G, the red display panel 10R and the blue display panel 10B as an example, first, the green display panel 10G, the red display panel 10R and the blue display panel 10B are fully lit at the same time, then the green projection picture 20G, the red projection picture 20R and the blue projection picture 20B all appear on the target projection surface 20 at the same time. At this time, the first column of the collected projection pixel image is green, the second column is green, the third column is yellow, the fourth to the eighth columns are white, the ninth column is purple, the tenth column is purple, and the eleventh column is blue. It can be inferred that the fourth to eighth columns of the green projection picture 20G are The 8th column of projection pixels are overlapping projection pixels 201, the 2nd to 6th columns of projection pixels in the red projection screen 20R are overlapping projection pixels 201, the 1st to 5th columns of projection pixels in the blue projection screen 20B are overlapping projection pixels 201, the 1st to 3rd columns of projection pixels in the green projection screen 20G are staggered projection pixels 202, the 1st column and the 7th to 8th columns of projection pixels in the red projection screen 20R are staggered projection pixels 202, and the 6th to 8th columns of projection pixels in the blue projection screen 20B are staggered projection pixels 202.

[0214] Fig.28 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0215] In one embodiment of the present application, Fig.28 As shown, S01: collecting images of each projection screen 200 on the target projection surface 20 to obtain projection screen features, including:

[0216] S011b: Light up the entire screen of one display panel 10, and light up the panel pixels in other display panels 10 row by row at the same time.

[0217] Among them, multiple panel pixels in the same team are arranged in sequence along the same direction, that is, multiple panel pixels arranged in sequence along the same direction can be regarded as panel pixels in the same team. After a display panel 10 is fully lit, when the panel pixels in other display panels 10 are lit team by team, the overlapping projection pixels 201 can be presented team by team.

[0218] S012b: collecting images of the projection screen 200 of the screen displayed by each display panel 10 on the target projection surface 20 at the first frequency to obtain projection screen features.

[0219] The first frequency is the frequency at which the panel pixels in the other display panels 10 are lit up in teams, that is, after one team of the other display panels 10 is lit up, the image of the projection screen 200 on the target projection surface 20 is captured once. As the other display panels 10 are lit up in teams, the images of the projection pixels on the target projection surface 20 that change in teams are captured, and the range of the pixel teams of the overlapping projection pixels 201 is obtained according to the color changes of the images.

[0220] The panel pixels of the same team may be panel pixels of the same column or panel pixels of the same row. When it is necessary to obtain information about overlap and misalignment of projection pixels in the column direction, the panel pixels are lit up team by team, which may include lighting up the panel pixels row by row. When it is necessary to obtain information about overlap and misalignment of projection pixels in the row direction, the panel pixels are lit up team by team, which may include lighting up the panel pixels column by column.

[0221] The following description will be made by taking the lighting of panel pixels row by row as an example.

[0222] by Fig.19 Take an example to illustrate, first light up the full screen of the green display panel 10G, then the green projection screen 20R appears on the target projection surface 20, then light up the first column of the red display panel 10R and the first column of the blue display panel 10B, and collect the image of the projection screen 200 on the target projection surface 20. At this time, the first column of the collected projection pixel image is green, the second column is green, the third column is yellow, the fourth column is white, and the fifth to eighth columns are green. It can be inferred that the green projection screen 20G is offset to the left by 2 columns of projection pixels relative to the red projection screen 20R, and the blue projection screen 20B is offset to the right by 1 column of projection pixels relative to the red projection screen 20R. It can also be inferred that the projection pixels from the 4th to the 8th columns of the green projection screen 20G are overlapping projection pixels 201, the projection pixels from the 2nd to the 6th columns of the red projection screen 20R are overlapping projection pixels 201, and the projection pixels from the 1st to the 5th columns of the blue projection screen 20B are overlapping projection pixels 201, the projection pixels from the 1st to the 3rd columns of the green projection screen 20G are staggered projection pixels 202, the projection pixels from the 1st column and the 7th to the 8th columns of the red projection screen 20R are staggered projection pixels 202, and the projection pixels from the 6th to the 8th columns of the blue projection screen 20B are staggered projection pixels 202.

[0223] Fig.29 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0224] In one embodiment of the present application, Fig.29As shown, S01: collecting images of each projection screen 200 on the target projection surface 20 to obtain projection screen features, including:

[0225] S011c: Light up the panel pixels in each display panel 10 one by one at the same time.

[0226] Among them, a plurality of panel pixels in the same team are arranged in sequence along the same direction, that is, a plurality of panel pixels arranged in sequence along the same direction can be regarded as panel pixels in the same team.

[0227] S012c: Capture images of the projection screen 200 of the screen displayed by each display panel 10 on the target projection surface 20 at the first frequency to obtain projection screen features.

[0228] The first frequency is the frequency at which the panel pixels in the display panel 10 are lit up in teams, that is, after each display panel 10 lights up a team at the same time, the image of the projection screen 200 on the target projection surface 20 is collected once. As the display panels 10 are lit up in teams, the images of the projection pixels on the target projection surface 20 that change in teams are collected, and the range of the pixel teams of the overlapping projection pixels 201 is obtained according to the color changes of the images.

[0229] The panel pixels of the same team may be panel pixels of the same column or panel pixels of the same row. When it is necessary to obtain information about overlap and misalignment of projection pixels in the column direction, the panel pixels are lit up team by team, which may include lighting up the panel pixels row by row. When it is necessary to obtain information about overlap and misalignment of projection pixels in the row direction, the panel pixels are lit up team by team, which may include lighting up the panel pixels column by column.

[0230] The following description will be made by taking the lighting of panel pixels row by row as an example.

[0231] by Fig.19For example, first, the first column of the green display panel 10G, the first column of the red display panel 10R, and the first column of the blue display panel 10B are lit up, and an image of the projection screen 200 on the target projection surface 20 is collected once. At this time, the collected image of the projection pixels includes 1 column of green, 1 column of red, and 1 column of blue; then, the second column of the green display panel 10G, the second column of the red display panel 10R, and the second column of the blue display panel 10B are lit up, and an image of the projection screen 200 on the target projection surface 20 is collected once. At this time, in the image of the collected projection pixels, the first column is green, the second column is green, the third column is red, the fourth column is purple, and the fifth column is blue; then the third column of the green display panel 10G, the third column of the red display panel 10R, and the third column of the blue display panel 10B are lit and the image of the projection screen 200 on the target projection surface 20 is collected once. At this time, in the image of the collected projection pixels, the first column is green, the second column is green, the third column is yellow, the fourth column is purple, the fifth column is purple, and the sixth column is blue. It can be inferred that the green projection screen 20G is offset to the left by 2 columns of projection pixels relative to the red projection screen 20R, and the blue projection screen 20B is offset to the right by 1 column of projection pixels relative to the red projection screen 20R. It can also be inferred that the projection pixels from the 4th to the 8th columns of the green projection screen 20G are overlapping projection pixels 201, the projection pixels from the 2nd to the 6th columns of the red projection screen 20R are overlapping projection pixels 201, and the projection pixels from the 1st to the 5th columns of the blue projection screen 20B are overlapping projection pixels 201, the projection pixels from the 1st to the 3rd columns of the green projection screen 20G are staggered projection pixels 202, the projection pixels from the 1st column and the 7th to the 8th columns of the red projection screen 20R are staggered projection pixels 202, and the projection pixels from the 6th to the 8th columns of the blue projection screen 20B are staggered projection pixels 202.

[0232] By lighting up at least one display panel 10 one by one and acquiring the image of the projection screen 200 on the target projection surface 20 at a first frequency, the position coordinates of the overlapping projection pixels 201 and the misaligned projection pixels can be inferred through the color changes and the number of acquisitions.

[0233] It should be noted that the above explanation is made by taking the lighting of panel pixels team by team as an example of lighting of panel pixels column by column. When the panel pixels need to be lit up row by row to obtain the information of overlapping and misalignment of projection pixels in the column direction, a similar column-by-column lighting method can be adopted, but the lighting is done team by team along different directions.

[0234] Fig.30 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0235] In one embodiment of the present application, Fig.30As shown, the screen alignment method of the display module 01 provided in the embodiment of the present application may also include:

[0236] S00: adjusting the position of at least a portion of the display panel 10 .

[0237] It can be understood that the methods provided in the previous embodiments are for fine-tuning the projection picture of the display module 01, and the adjustment of the position of the system panel in this embodiment can be regarded as coarse-tuning the projection picture of the display module 01. Through coarse-tuning, the misalignment between different projection pictures 200 on the target projection surface 20 can be prevented from being too large, so as to avoid losing too many pictures after fine-tuning.

[0238] Based on this embodiment, the display module provided in the embodiment of the present application may have a coarse adjustment function. For example, in response to a user's operation, the mechanical structure of the display module may control the position of the display panel to change.

[0239] Furthermore, step S00 may be performed before step S01 .

[0240] Fig.31 A schematic flow chart of a method for aligning a display module provided in an embodiment of the present application.

[0241] In one embodiment of the present application, Fig.31 As shown, the screen alignment method of the display module 01 provided in the embodiment of the present application includes:

[0242] S02: Based on the projection picture features, determine whether the misalignment of different projection pictures 200 on the target projection surface 20 along the first direction exceeds the width of 0.5 projection pixels;

[0243] S1: If the width exceeds 0.5 projection pixels, a plurality of target display data sets are acquired based on the projection picture feature and the initial image data D0 of the image IM to be displayed.

[0244] That is to say, before fine-tuning the projection picture 200 of the display module 01, it is determined whether fine-tuning is required based on the projection picture characteristics. In this embodiment, if the misalignment of different projection pictures 200 on the target projection surface 20 along the first direction exceeds the width of 0.5 projection pixels, fine-tuning is performed; otherwise, the picture alignment process is terminated without fine-tuning.

[0245] It should be noted that, when multiple projection pixels for displaying the same pixel in the image to be displayed IM overlap with each other to achieve color mixing, the misalignment of different projection pixels for displaying the same pixel in the image to be displayed IM in the first direction exceeds the width of 0.5 projection pixels, and they are deemed not to overlap, which means that the misalignment of different projection images 200 on the target projection surface 20 along the first direction exceeds the width of 0.5 projection pixels. When multiple projection pixels for displaying the same pixel in the image to be displayed IM are separated by a preset distance to achieve color mixing, the distance between different projection pixels for displaying the same pixel in the image to be displayed IM is greater than the preset distance by the width of 0.5 projection pixels, and they are deemed not to overlap, which means that the misalignment of different projection images 200 on the target projection surface 20 along the first direction exceeds the width of 0.5 projection pixels.

[0246] Fig.32 A schematic diagram of a display module provided in an embodiment of the present application.

[0247] like Fig.32 As shown, an embodiment of the present application provides a display module 01, which includes multiple display panels 10 and a control module 30. The control module 30 is used to execute the method provided by any of the above embodiments to achieve alignment control of the projection screen 200 of the display module 01.

[0248] like Figure 1 As shown, the embodiment of the present application provides a display module 01, which includes a plurality of display panels 10. The display screens of the display panels 10 are projected onto a target projection surface 20 to present a corresponding projection screen 200. The relationship between the panel pixels in the display panel 10 and the projection pixels in the projection screen 200 has been described in the above embodiment and will not be repeated here.

[0249] When the misalignment of at least two projection images along the first direction on the target projection surface exceeds a preset value, the overlapping panel pixels 101 in different display panels 10 display the same image and the misaligned panel pixels 102 in different display panels 10 display the first grayscale image; the overlapping panel pixels 101 in the display panel 10 correspond to the overlapping projection pixels 201 in the projection image 200 that overlap with other projection images 200, and the misaligned panel pixels 102 in the display panel 10 correspond to the misaligned projection pixels 202 in the projection image 200 that are misaligned with at least one other projection image 200.

[0250] For example, Figure 2 and Figure 4As shown, the overlapping panel pixels 101 in each display panel 10 are used to display the pictures corresponding to the pixels in the 1st to 7th columns in the image IM to be displayed. Correspondingly, the different projection pictures 200 on the target projection surface 20 all show the same picture; and the staggered panel pixels 102 in each display panel 10 are used to display the same grayscale picture.

[0251] In one embodiment of the present application, Figure 4 As shown, the first grayscale image is a black image, that is, the staggered panel pixels 102 in each display panel 10 are all used to display a black image, and correspondingly, each staggered projection pixel 202 on the target projection surface 20 displays a black image.

[0252] In addition, the first grayscale image may also be other images. For example, the first grayscale image displayed by the staggered panel pixel 102 may be the same as or similar to the image displayed by the adjacent overlapping panel pixel 101. Assuming that the projection image features are as follows: Figure 2 As shown, the first grayscale image displayed by the leftmost misaligned panel pixel 102 in the red display panel 10R can be the same as the image displayed by the second column of panel pixels on the left (overlapping panel pixels 101), the first grayscale image displayed by the rightmost misaligned panel pixel 102 in the green display panel 10G can be the same as the image displayed by the second column of panel pixels on the right (overlapping panel pixels 101), and the first grayscale image displayed by the rightmost misaligned panel pixel 102 in the blue display panel 10B can be the same as the image displayed by the second column of panel pixels on the right (overlapping panel pixels 101).

[0253] In one embodiment of the present application, the display module 01 includes a first color display panel 10G, a second color display panel 10R, and a third color display panel 10B. The first color display panel 10G includes the first to L teams of first color panel pixels arranged along the second direction, the second color display panel 10R includes the first to L teams of second color panel pixels arranged in the third direction, and the third color display panel 10B includes the first to L teams of third color panel pixels arranged in the fourth direction.

[0254] The panel pixels in the same team may be panel pixels in the same column or panel pixels in the same row. The following description will be made by taking the panel pixels in the same team as panel pixels in the same column as an example.

[0255] For example, the first color display panel 10G is a green display panel 10G and the green display panel 10G includes green panel pixels from the 1st column to the 8th column arranged along the second direction, the second color display panel 10R is a red display panel 10R and the red display panel 10R includes red panel pixels from the 1st column to the 8th column arranged along the third direction, and the third color display panel 10B is a blue display panel 10B and the blue display panel 10B includes blue panel pixels from the 1st column to the 8th column arranged along the fourth direction.

[0256] In a first direction parallel to the target projection surface 20, the first color projection picture 20G and the third color projection picture 20B are both offset by n projection pixels to the first projection direction relative to the second color projection picture 20R. The first color projection picture 20G is the projection of the picture displayed by the first color display panel 10G on the target projection surface 20, the second color projection picture 20R is the projection of the picture displayed by the second color display panel 10R on the target projection surface 20, and the third color projection picture 20B is the projection of the picture displayed by the third color display panel 10B on the target projection surface 20. For example, Figure 4 As shown, the second color projection screen 20R is the red projection screen 20R, the first color projection screen 20G is the green projection screen 20G, and the third color projection screen 20B is the blue projection screen 20B. The green projection screen 20G and the blue projection screen 20B are both offset to the right by one projection pixel on the target projection surface 20 relative to the red projection screen 20R, that is, the green projection screen 20G and the blue projection screen 20B are both displaced to the right relative to the red projection screen 20R and the width of the dislocation is substantially equal to the width of one projection pixel.

[0257] The projections of the second direction, the third direction, and the fourth direction on the target projection surface 20 are the same as the first direction. Figure 1 As shown, the light emitting surfaces of the multiple display panels 10 included in the display module 01 are not in the same plane, but the projection images 200 of the display images of the display panels 10 on the target projection surface 20 are in the same plane. Figure 1 and Figure 2 and Figure 4 , the images displayed by the first color panel pixels of the 1st to Lth columns arranged along the second direction are projected onto the target projection surface 20 to form images displayed by the first color panel pixels of the 1st to Lth columns arranged along the first direction, and it can be understood that the projection of the second direction on the target projection surface 20 is the same as the first direction. Correspondingly, the projections of the third direction and the fourth direction on the target projection surface 20 are the same as the first direction.

[0258] In addition, the first projection orientation is the same as the first direction, that is, if the first projection orientation is on the right side, then the first direction points from the left side to the right side.

[0259] In the first color display panel 10G, the first color panel pixels of the 1st to (Ln)th teams arranged along the second direction are overlapping panel pixels 101, and the first color panel pixels of the (L-n+1)th to Lth teams are staggered panel pixels 102; in the second color display panel 10R, the second color panel pixels of the (n+1)th to Lth teams arranged along the third direction are overlapping panel pixels 101, and the second color panel pixels of the 1st to nth teams are staggered panel pixels 102; in the third color display panel 10B, the third color panel pixels of the 1st to (Ln)th teams arranged along the fourth direction are overlapping panel pixels 101, and the third color panel pixels of the (L-n+1)th to Lth teams are staggered panel pixels 102.

[0260] That is, the 1st to (Ln)th teams of first color panel pixels arranged along the second direction, the (n+1)th to Lth teams of second color panel pixels arranged along the third direction, and the 1st to (Ln)th teams of third color panel pixels arranged along the fourth direction display the same picture in the image IM to be displayed.

[0261] For example, Figure 4 As shown, n=1, L=8, then Ln=7, n+1=2, the 1st to 7th columns of green panel pixels arranged along the second direction, the 2nd to 8th columns of red panel pixels arranged along the third direction, and the 1st to 7th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 1st to 7th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 1st to 7th columns of pixels in the image to be displayed IM.

[0262] In a technical solution corresponding to this embodiment, combined with Figure 2 and Figure 6 The 1st to (Ln)th teams of first color panel pixels arranged along the second direction in the first color display panel 10G, the (n+1)th to Lth teams of second color panel pixels arranged along the third direction in the second color display panel 10R, and the 1st to (Ln)th teams of third color panel pixels arranged along the fourth direction in the third color display panel 10B all display the (n+1)th to Lth teams of pictures of the image IM to be displayed.

[0263] For example, Figure 4As shown, n=1, L=8, then Ln=7, n+1=2, the 1st to 7th columns of green panel pixels arranged along the second direction, the 2nd to 8th columns of red panel pixels arranged along the third direction, and the 1st to 7th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 2nd to 8th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 2nd to 8th columns of pixels in the image to be displayed IM.

[0264] In a technical solution corresponding to this embodiment, combined with Figure 2 and Figure 4 , Figure 8 The 1st to (Ln)th teams of first color panel pixels arranged along the second direction in the first color display panel 10G, the (n+1)th to Lth teams of second color panel pixels arranged along the third direction in the second color display panel 10R, and the 1st to (Ln)th teams of third color panel pixels arranged along the fourth direction in the third color display panel 10B all display the 1st to (Ln)th teams of images of the image IM to be displayed.

[0265] For example, Figure 4 As shown, n=1, L=8, then Ln=7, n+1=2, the 1st to 7th columns of green panel pixels arranged along the second direction, the 2nd to 8th columns of red panel pixels arranged along the third direction, and the 1st to 7th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 1st to 7th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 1st to 7th columns of pixels in the image to be displayed IM.

[0266] It should be noted that the above description is based on the example of the misalignment of projection pixel columns in the row direction of projection images of different colors, and the display scheme of the display images of each color display panel is described as an example. It can be understood that the technical solution of this embodiment can also be used to determine the display scheme of the display images of each color display panel when there is a misalignment of projection pixel rows in the column direction of projection images of different colors, and this will not be repeated.

[0267] In one embodiment of the present application, the display module 01 includes a first color display panel 10G, a second color display panel 10R, and a third color display panel 10B. The first color display panel 10G includes the first to L teams of first color panel pixels arranged along the second direction, the second color display panel 10R includes the first to L teams of second color panel pixels arranged in the third direction, and the third color display panel 10B includes the first to L teams of third color panel pixels arranged in the fourth direction.

[0268] The panel pixels in the same team may be panel pixels in the same column or panel pixels in the same row. The following description will be made by taking the panel pixels in the same team as panel pixels in the same column as an example.

[0269] For example, the first color display panel 10G is a green display panel 10G and the green display panel 10G includes green panel pixels from the 1st column to the 8th column arranged along the second direction, the second color display panel 10R is a red display panel 10R and the red display panel 10R includes red panel pixels from the 1st column to the 8th column arranged along the third direction, and the third color display panel 10B is a blue display panel 10B and the blue display panel 10B includes blue panel pixels from the 1st column to the 8th column arranged along the fourth direction.

[0270] In a first direction parallel to the target projection surface 20, the second color projection picture 20R is offset by n projection pixels to the first projection direction relative to the first color projection picture 20G, and the third color projection picture 20B is offset by m projection pixels to the first projection direction relative to the second color projection picture 20R; the first color projection picture 20G is the projection of the picture displayed by the first color display panel 10G on the target projection surface 20, the second color projection picture 20R is the projection of the picture displayed by the second color display panel 10R on the target projection surface 20, and the third color projection picture 20B is the projection of the picture displayed by the third color display panel 10B on the target projection surface 20. For example, Fig.12 As shown, the second color projection screen 20R is the red projection screen 20R, the first color projection screen 20G is the green projection screen 20G, and the third color projection screen 20B is the blue projection screen 20B. The red projection screen 20R is offset to the right by 1 projection pixel on the target projection surface 20 relative to the blue projection screen 20G, and the blue projection screen 20B is offset to the right by 1 projection pixel on the target projection surface 20 relative to the red projection screen 20R, that is, the red projection screen 20R is displaced to the right relative to the blue projection screen 20G and the width of the dislocation is substantially equal to the width of 1 projection pixel, and the blue projection screen 20B is displaced to the right relative to the red projection screen 20R and the width of the dislocation is substantially equal to the width of 1 projection pixel.

[0271] The projections of the second direction, the third direction, and the fourth direction on the target projection surface 20 are the same as the first direction. Figure 1 As shown, the light emitting surfaces of the multiple display panels 10 included in the display module 01 are not in the same plane, but the projection images 200 of the display images of the display panels 10 on the target projection surface 20 are in the same plane. Figure 1 and Fig.12, the images displayed by the first color panel pixels of the 1st to Lth columns arranged along the second direction are projected onto the target projection surface 20 to form images displayed by the first color panel pixels of the 1st to Lth columns arranged along the first direction, and it can be understood that the projection of the second direction on the target projection surface 20 is the same as the first direction. Correspondingly, the projections of the third direction and the fourth direction on the target projection surface 20 are the same as the first direction.

[0272] In addition, the first projection orientation is the same as the first direction, that is, if the first projection orientation is on the right side, then the first direction points from the left side to the right side.

[0273] In the first color display panel 10G, the first color panel pixels from the (n+m+1)th team to the Lth team arranged along the second direction are overlapping panel pixels 101 and the first color panel pixels from the 1st team to the (n+m)th team are staggered panel pixels 102; in the second color display panel 10R, the second color panel pixels from the (m+1)th team to the (Ln)th team arranged along the third direction are overlapping panel pixels 101 and the first color panel pixels from the (L-n+1)th team to the Lth team are staggered panel pixels 102; in the third color display panel 10B, the third color panel pixels from the 1st team to the (Lnm)th team arranged along the fourth direction are overlapping panel pixels 101 and the third color panel pixels from the 1st team to the (Ln-m+1)th team are staggered panel pixels 102.

[0274] That is, the (n+m+1)th to Lth teams of first color panel pixels arranged along the second direction, the (m+1)th to (Ln)th teams of second color panel pixels arranged along the third direction, and the 1st to (Lnm)th teams of third color panel pixels arranged along the fourth direction display the same picture in the image IM to be displayed.

[0275] For example, Fig.12 As shown, n=1, m=1, L=8, then n+m+1=3, m+1=2, Ln=7, Lnm=6, the 3rd to 8th columns of green panel pixels arranged along the second direction, the 2nd to 7th columns of red panel pixels arranged along the third direction, and the 1st to 6th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the same 6 columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the same 6 columns of pixels in the image to be displayed IM.

[0276] In a technical solution corresponding to this embodiment, combined with Fig.12 and Fig.13The (n+m+1)th to (Ln)th first color panel pixels arranged along the second direction in the first color display panel 10G, the (m+1)th to (Ln)th second color panel pixels arranged along the third direction in the second color display panel 10R, and the 1st to (Lnm)th third color panel pixels arranged along the fourth direction in the third color display panel 10B all display the (m+1)th to (Ln)th images of the image IM to be displayed.

[0277] For example, Fig.13 As shown, n=1, m=1, L=8, then n+m+1=3, m+1=2, Ln=7, Lnm=6, the 3rd to 8th columns of green panel pixels arranged along the second direction, the 2nd to 7th columns of red panel pixels arranged along the third direction, and the 1st to 6th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 2nd to 7th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 2nd to 7th columns of pixels in the image to be displayed IM.

[0278] In a technical solution corresponding to this embodiment, combined with Fig.12 and Fig.15 The (n+m+1)th to (Ln)th first color panel pixels arranged along the second direction in the first color display panel 10G, the (m+1)th to (Ln)th second color panel pixels arranged along the third direction in the second color display panel 10R, and the 1st to (Lnm)th third color panel pixels arranged along the fourth direction in the third color display panel 10B all display the (n+m+1)th to (Lnm)th images of the image IM to be displayed.

[0279] For example, Fig.15 As shown, n=1, m=1, L=8, then n+m+1=3, m+1=2, Ln=7, Lnm=6, the 3rd to 8th columns of green panel pixels arranged along the second direction, the 2nd to 7th columns of red panel pixels arranged along the third direction, and the 1st to 6th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 2nd to 7th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 3rd to 8th columns of pixels in the image to be displayed IM.

[0280] In a technical solution corresponding to this embodiment, combined with Fig.12 and Fig.17The (n+m+1)th to (Ln)th first color panel pixels arranged along the second direction in the first color display panel 10G, the (m+1)th to (Ln)th second color panel pixels arranged along the third direction in the second color display panel 10R, and the 1st to (Lnm)th third color panel pixels arranged along the fourth direction in the third color display panel 10B all display the 1st to (Lnm)th images of the image IM to be displayed.

[0281] For example, Fig.17 As shown, n=1, m=1, L=8, then n+m+1=3, m+1=2, Ln=7, Lnm=6, the 3rd to 8th columns of green panel pixels arranged along the second direction, the 2nd to 7th columns of red panel pixels arranged along the third direction, and the 1st to 6th columns of blue panel pixels arranged along the fourth direction are all used to display the pictures corresponding to the 2nd to 7th columns of pixels in the image to be displayed IM. Therefore, the overlapping projection pixels 201 in each projection picture 200 in the target projection surface 20 can display the pictures corresponding to the 1st to 6th columns of pixels in the image to be displayed IM.

[0282] It should be noted that the above description is based on the example of the misalignment of projection pixel columns in the row direction of projection images of different colors, and the display scheme of the display images of each color display panel is described as an example. It can be understood that the technical solution of this embodiment can also be used to determine the display scheme of the display images of each color display panel when there is a misalignment of projection pixel rows in the column direction of projection images of different colors, and this will not be repeated.

[0283] Each display panel 10 includes the 1st to Lth teams of panel pixels arranged along the first panel direction, and the projection of the first panel direction on the target projection surface 20 is the same as the first direction. For example, the display module 01 includes a green display panel 10G, a red display panel 10R, and a blue display panel 10B, and the green display panel 10G includes the 1st to 8th columns of green panel pixels arranged along the second direction, the red display panel 10R includes the 1st to 8th columns of red panel pixels arranged along the third direction, and the blue display panel 10B includes the 1st to 8th columns of blue panel pixels arranged along the fourth direction, the projection of the second direction on the target projection surface 20 is the same as the first direction, the projection of the third direction on the target projection surface 20 is the same as the first direction, and the projection of the fourth direction on the target projection surface 20 is the same as the first direction, then the second direction, the third direction, and the fourth direction are the first panel direction of the green display panel 10G, the first panel direction of the red display panel 10R, and the first panel direction of the blue display panel 10B, respectively.

[0284] When the number of teams of staggered projection pixels 202 along the first direction of all projection images 200 on the target projection surface 20 is greater than or equal to 2, the overlapping panel pixels 101 in each display panel 10 display the i-th to (Lj)-th teams of images in the image IM to be displayed, where i is greater than or equal to 2 and j is greater than or equal to 1.

[0285] For example, Fig.13 As shown, the red projection picture 20R is offset by 1 projection pixel to the right on the target projection surface 20 relative to the green projection picture 20G, and the blue projection picture 20B is offset by 1 projection pixel to the right on the target projection surface 20 relative to the red projection picture 20R, then the number of columns of staggered projection pixels 202 of all projection pictures 200 along the first direction on the target projection surface 20 is equal to 2. At this time, the overlapping panel pixels 101 in each display panel 10 display the 2nd to 7th columns of the image IM to be displayed, that is, i=2, j=1, L=8, 8-1=7.

[0286] For example, Fig. 20 As shown, the red projection picture 20R is offset by 2 projection pixels to the right on the target projection surface 20 relative to the green projection picture 20G, and the blue projection picture 20B is offset by 1 projection pixel to the right on the target projection surface 20 relative to the red projection picture 20R, then the number of columns of staggered projection pixels 202 of all projection pictures 200 along the first direction on the target projection surface 20 is equal to 3. At this time, the overlapping panel pixels 101 in each display panel 10 display the 3rd to 7th columns of the image IM to be displayed, that is, i=3, j=1, L=8, 8-1=7.

[0287] It should be noted that the above description is based on the example of the misalignment of projection pixel columns in the row direction of projection images of different colors, and the display scheme of the display images of each color display panel is described as an example. It can be understood that the technical solution of this embodiment can also be used to determine the display scheme of the display images of each color display panel when there is a misalignment of projection pixel rows in the column direction of projection images of different colors, and this will not be repeated.

[0288] In one embodiment of the present application, Fig.23 As shown, when the misalignment of at least two projection images along the first direction on the target projection surface 20 exceeds a preset value, the resolution of the image to be displayed IM presented by the overlapping panel pixels in the display panel 10 is lower than the resolution of the image to be displayed IM. That is, the display module reduces the resolution of the image to be displayed and displays it through the overlapping panel pixels in the display panel 10, so the user can see a relatively complete image to be displayed on the target projection surface 20.

[0289] It should be noted that Fig.23The method of reducing the display resolution of the display panel 10 in the row direction by taking pixel sampling as an example is illustrated. In some embodiments, when there is a misalignment of projection pixel columns in the column direction of projection images of different colors, the display resolution of the display panel 10 in the column direction may also be reduced. For example, the display resolution of the display panel 10 in the column direction may be reduced by sampling pixel rows.

[0290] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
