[0002] In recent years, spliced displays have been widely used. Spliced displays usually include multiple display screens, with different display screens showing different images. The images displayed by multiple display screens can be spliced together to form a complete image.
[0003] Since a spliced display is composed of multiple different screens, and each screen displays a different image, the edge parts of each spliced display, especially the parts connected to other spliced displays, will appear blurred or misaligned, affecting the image display.

The first dynamic display area and the second dynamic display area have the same sub-pixel rows / columns and a one-to-one correspondence. The first normally black display area includes a first normally black sub-area facing the blank, and the second normally black display area includes a third normally black sub-area facing the blank.

[0018] In this embodiment, it is determined that there is no first sub-normally black display area corresponding to a pixel unit in the first sub-display screen 1, and no third sub-normally black display area corresponding to a pixel unit in the second sub-display screen. Both are caused by the misalignment of the sub-display screens, and therefore, the number of sub-pixel rows or sub-pixel columns contained in the two are the same.

[0067] It should be noted that since the method of the embodiment of the present application is executed in an electronic device, the processing objects of each electronic device exist in the form of data or information. For example, time is actually time information. It can be understood that if size, quantity, position, etc. are mentioned in subsequent embodiments, the corresponding data exist for the electronic device to process. The details will not be repeated here.
[0068] The embodiments of the present application provide a spliced display and a driving method, which are described in detail below.
[0069] See also Figure 1 , Figure 1 This is a schematic diagram of an embodiment of a spliced display provided in an embodiment of the present application. Figure 1 In the illustrated embodiment, the tiled display includes at least two sub-displays, including a first sub-display and a second sub-display. The first sub-display and the second sub-display each include sub-pixels arranged in a multi-row and multi-column array. The first sub-display and the second sub-display are staggered in a first direction, with the sub-pixels being offset by N rows or columns.
[0070] At the same time, because the first sub-display screen and the second sub-display screen are offset by N rows of sub-pixels or N columns of sub-pixels in the first direction, the first sub-display screen also has a first dynamic display area and a first normally black display area; while the second sub-display screen has a second dynamic display area and a second normally black display area. The first dynamic display area and the second dynamic display area contain the same sub-pixel rows or sub-pixel columns and have a one-to-one correspondence; the first normally black display area includes a first normally black sub-display area facing the blank area, and the second normally black display area includes a third non-sub-display area facing the blank area.
[0071] The first sub-normally black display area includes N rows of sub-pixels, or the first sub-display area includes N columns of sub-pixels; similarly, the third sub-normally black display area includes N rows of sub-pixels, or the third sub-display area includes N columns of sub-pixels. The first sub-display screen and the second sub-display screen are arranged differently, and the sub-pixels therein are also misaligned differently.
[0072] The spliced display provided in an embodiment of the present application includes at least two sub-displays, including a first sub-display and a second sub-display. The first sub-display, the second sub-display, and the third sub-display have the same sub-pixel size and number in the horizontal or vertical direction. Furthermore, the first sub-display and the second sub-display are offset by N rows or N columns of sub-pixels in the horizontal or vertical direction. This spliced display effectively improves the precision of the moving display by offsetting N sub-pixels and avoids problems such as misalignment and blurring at the junction of the first sub-display and the second sub-display.
[0073] exist Figure 1 In the illustrated embodiment, the first sub-display screen 1 and the second sub-display screen 2 are arranged vertically above each other; specifically, the first sub-display screen 1 is arranged above the second sub-display screen 2. The first and second sub-display screens 1 and 2 have the same sub-pixel size and number in the horizontal direction, and the sub-pixels in the first and second sub-display screens 1 and 2 are offset by N columns in the horizontal direction.
[0074] In this case, the first sub-display screen 1 includes a first dynamic display area and a first normally black display area; while the second sub-display screen 2 correspondingly includes the first dynamic display area and the second normally black display area. The first dynamic display area includes sub-pixels arranged in a multi-row, multi-column array, and the second dynamic display area also includes sub-pixels arranged in a multi-row, multi-column array. The multiple columns of sub-pixels in the first dynamic display area are identical to the multiple columns of sub-pixels in the second dynamic display area, and are arranged in a one-to-one correspondence.
[0075] Among them, the sub-pixels arranged in a multi-row and multi-column array can be red sub-pixels, green sub-pixels and blue sub-pixels, that is, RGB sub-pixels. Typically, the sub-pixels in each row (or column) of the sub-display screen are the same, and the sub-pixels in each column (or row) are arranged crosswise in the order of RGB. In other embodiments of the present application, the sub-pixels arranged in a multi-row and multi-column array can also be red sub-pixels, green sub-pixels, blue sub-pixels and white sub-pixels, that is, RGBW sub-pixels. Similarly, the sub-pixels in each row (or column) of the sub-display screen are the same, and the sub-pixels in each column (or row) are arranged crosswise in the order of RGBW.
[0076] exist Figure 1In the illustrated embodiment, the first normally black display area also includes a second sub-normally black display area, with the second sub-normally black display area and the first sub-normally black display area respectively disposed at opposite ends of the first dynamic display area. Specifically, due to the misalignment between the first sub-display screen and the second sub-display screen, no sub-pixels in the second sub-display screen correspond to the first sub-normally black display area. This means that the first normally black display area includes the first sub-normally black display area facing the empty space. This first sub-normally black display area facing the empty space prevents the first sub-normally black display area from displaying images properly.
[0077] Since a pixel usually includes three or four sub-pixels, the sub-pixel rows / columns contained in the first dynamic display area and the second dynamic display area that can normally display the picture are both multiples of 3 or 4, so that three or four adjacent sub-pixels can form a pixel to normally display the picture.
[0078] When the first sub-normally black display area cannot display the picture normally, the sub-pixels in the second sub-normally black display area cannot form a complete pixel, resulting in the sub-pixels in the second sub-normally black display area also being unable to display the picture normally, making the second sub-normally black display area a normally black display area that cannot display the picture.
[0079] Because the first and second sub-display screens are misaligned, a first normally black display area is generated in the first sub-display screen, and a second normally black display area is generated in the second sub-display screen. The first normally black display area includes a first normally black sub-area facing the blank area, and the second normally black display area also includes a third normally black sub-area facing the blank area.
[0080] Please refer to Figure 1 ,exist Figure 1 In the example, some of the rightmost sub-pixels in the second sub-display have no corresponding pixels in the first sub-display, rendering them unable to display images. Therefore, these sub-pixels form the third sub-normally black display area. The third sub-normally black display area is identical to the first sub-normally black display area in that both are normally black areas facing the empty space. That is, neither the first nor the third sub-normally black display area has a sub-pixel corresponding to it.
[0081] It should be noted that the first normally black display area and the second normally black display area in the embodiment of the present application are both caused by the misalignment between different sub-display screens, and the sub-display screen itself does not include a normally black display area that cannot display an image.
[0082] like Figure 2 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 2 In the embodiment shown, the spliced display also includes a first sub-display screen and a second sub-display screen; Figure 1 The embodiment shown differs in that Figure 2The first sub-display screen 1 and the second sub-display screen 2 are arranged along the horizontal direction; specifically, the second sub-display screen 2 is arranged on the right side of the first sub-display screen 1.
[0083] At the same time, the sub-pixel size and number of the first sub-display screen 1 and the second sub-display screen 2 in the vertical direction are the same; Figure 2 The first sub-display screen and the second sub-display screen are offset in the vertical direction by N rows of sub-pixels.
[0084] exist Figure 2 In the illustrated embodiment, the first sub-display screen 1 also includes a first dynamic display area capable of displaying images, and a first normally black display area incapable of displaying images. Similarly, the second sub-display screen 2 also includes a second dynamic display area capable of displaying images, and a second normally black display area incapable of displaying images.
[0085] at the same time, Figure 2 In the illustrated embodiment, the first normally black display area also includes a first normally black sub-area and a second normally black sub-area; and the second normally black display area includes a third normally black sub-area and a fourth normally black sub-area. Furthermore, the first and second normally black sub-areas are positioned on either side of the first dynamic display area; while the third dynamic display area and the third normally black sub-area are positioned on either side of the fourth normally black sub-area.
[0086] exist Figure 1 and Figure 2 In the illustrated embodiment, no sub-pixels in the second sub-display screen 2 correspond to the first sub-normally black display area, and no sub-pixels in the first sub-display screen 1 correspond to the third sub-normally black display area. Both the first sub-normally black display area and the third sub-normally black display area include N rows or N columns of sub-pixels.
[0087] In an embodiment of the present application, if three sub-pixels constitute a pixel, then when N is 3a-2, the first normally black display area includes 3a-2 rows (or columns) of sub-pixels, and at this time the second sub-normally black display area can include 2 rows (or columns) of sub-pixels.
[0088] Specifically, when the first sub-normally black display area includes 3a-2 rows of sub-pixels, the second sub-normally black display area includes 1 row of sub-pixels; when the first sub-normally black display area includes 3a-1 rows of sub-pixels, the second sub-normally black display area includes 2 rows of sub-pixels; the first sub-normally black display area includes 3a rows of sub-pixels, and the second sub-normally black display area includes 0 rows of sub-pixels.
[0089] Please refer to Figure 1 ,exist Figure 1In the illustrated embodiment, when a pixel includes three sub-pixels, N can be 1. In this case, the first sub-display screen 1 and the second sub-display screen 2 are horizontally offset by one column of sub-pixels. In this case, the first sub-normally black display area includes one column of sub-pixels; similarly, the third sub-normally black display area also includes one column of sub-pixels. In this case, the second sub-normally black display area includes 3-1=2 columns of sub-pixels.
[0090] In some other embodiments, the first sub-display screen 1 and the second sub-display screen 2 may be horizontally offset by two columns of sub-pixels. In this case, the first sub-normally black display area includes two columns of sub-pixels. Similarly, the third sub-normally black display area also includes two columns of sub-pixels. The second sub-normally black display area includes 3-2=1 column of sub-pixels.
[0091] The first sub-display screen 1 and the second sub-display screen 2 may also be horizontally offset by three columns of sub-pixels. In this case, the first sub-normally black display area includes three columns of sub-pixels. Similarly, the third sub-normally black display area also includes three columns of sub-pixels. The second sub-normally black display area includes 3-3=0 columns of sub-pixels.
[0092] When N is 2, both the first and second sub-normally black display areas include 4 columns of sub-pixels, but the second sub-normally black display area still includes 2 columns of sub-pixels. Similarly, when N is 2 and the first sub-normally black display area includes 5 columns of sub-pixels, the second sub-normally black display area includes 1 column of sub-pixels. When N is 3, the first sub-normally black display area includes 6 columns of sub-pixels, while the second sub-normally black display area includes 0 columns of sub-pixels.
[0093] In other embodiments of the present application, if a pixel includes four sub-pixels, when the first sub-normally black display area includes 4a-3 rows of sub-pixels, the second sub-normally black display area includes 3 rows of sub-pixels; when the first sub-normally black display area includes 4a-2 rows of sub-pixels, the second sub-normally black display area includes 2 rows of sub-pixels; when the first sub-normally black display area includes 4a-1 rows of sub-pixels, the second sub-normally black display area includes 1 row of sub-pixels; the first sub-normally black display area includes 4a rows of sub-pixels, and the second sub-normally black display area includes 0 rows of sub-pixels.
[0094] Specifically, when N is 1 and the first sub-normally black display area includes one row of sub-pixels, the second sub-normally black display area includes three rows of sub-pixels. When N is 3 and the first sub-normally black display area includes five rows of sub-pixels, the second sub-normally black display area still includes three rows of sub-pixels.
[0095] That is, in an embodiment of the present application, when a pixel includes three sub-pixels, no matter how many rows (or columns) of sub-pixels are offset between the first sub-display screen and the second sub-display screen, the second sub-normally black display area only includes one row of sub-pixels, or two rows of sub-pixels, or zero rows of sub-pixels, that is, there is no second sub-normally black display area.
[0096] Similarly, when a pixel includes four sub-pixels, regardless of the number of rows (or columns) of sub-pixels offset between the first and second sub-display screens, the second sub-normally black display area only includes one row, two rows, three rows, or zero rows of sub-pixels. When the second sub-normally black display area includes a pilot sub-pixel, there is no second sub-normally black display area.
[0097] In the embodiment of the present application, the number of rows or columns of sub-pixels in the first normally black sub-display area is usually the same as the number of rows or columns of sub-pixels in the third non-sub-display area.
[0098] exist Figure 1 and Figure 2 In the illustrated embodiment, the first normally black display area includes not only the first normally black sub-area but also the second normally black sub-area. Furthermore, the second normally black display area also includes the third and fourth normally black sub-areas. The second and fourth normally black sub-areas are typically positioned opposite each other.
[0099] When the number of rows or columns of sub-pixels in the first sub-normally black display area is the same as the number of rows or columns of sub-pixels in the third sub-normally black display area; the number of rows or columns in the second sub-normally black display area is usually also the same as the number of rows or columns of sub-pixels in the fourth sub-normally black display area.
[0100] like Figure 3 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 3 In the example, the tiled display includes a first sub-display 1 and a second sub-display 2; each of the first sub-display 1 and the second sub-display 2 is composed of multiple sub-pixels. The multiple sub-pixels can be red pixels, green pixels, and blue pixels, i.e., RGB pixels. Normally, the multiple sub-pixels in the first and second sub-displays are of the same sub-pixel type, for example, all R sub-pixels, while the multiple sub-pixels in the same row are arranged in an interleaved, RGB order.
[0101] exist Figure 3 In the embodiment shown, the first sub-display screen 1 and the second sub-display screen 2 are offset by one sub-pixel. Figure 3 The multiple sub-pixels in the bold area in the figure are sub-pixels A1-An; and the multiple sub-pixels in the partial area of the second sub-display screen connected to the first sub-display screen 1 are B1-Bn.
[0102] When the first sub-display screen 1 and the second sub-display screen 2 are horizontally offset by one sub-pixel, sub-pixels A1, A2, and A3, which originally formed a pixel in the first sub-display screen 1, are offset due to A1. Consequently, sub-pixels A2, A3, and A4 in the first sub-display screen 1 form a new pixel. At this point, the sub-pixel arrangement within a pixel changes from RGB to GBR. In the second sub-display screen 2, sub-pixels B1, B2, and B3 also form the pixel within the second sub-display screen; that is, the pixels are still arranged in RGB order.
[0103] In the above embodiment, among the pixels corresponding to the area connected to the second sub-display screen 2 in the first sub-display screen 1, the first sub-pixel and the last two sub-pixels correspond to grayscale 0 and do not display the image. The same is true for the pixels in other rows of the first sub-display screen, where the first sub-pixel and the last two sub-pixels do not display the image. Figure 3 In the left and right sides of the first sub-display screen 1, the three columns corresponding to the first sub-pixel and the last two sub-pixels in each row do not display any image. This is because the last two pixels in each row of the first sub-display screen 1 cannot form a complete pixel, and therefore cannot display any image.
[0104] The first sub-pixel in each row of the first sub-display screen 1 constitutes a column of sub-pixels. This column of sub-pixels cannot display images, and this column of sub-pixels is the first sub-normally black display area. Similarly, the last two sub-pixels in each row of the first sub-display screen constitute two columns of sub-pixels. These two columns of sub-pixels cannot display images, and these two columns of images are the second sub-normally black display area.
[0105] For the second sub-display screen 2, the sub-pixels corresponding to sub-pixels Bn-2 and Bn-1 in the second sub-display screen are An-1 and An. However, sub-pixels An-1 and An cannot form a complete pixel unit, resulting in sub-pixels An-1 and An being unable to display images. Consequently, sub-pixels Bn-2, Bn-1, and Bn in the second sub-display screen 2 are also unable to display images. In other words, sub-pixels Bn-2, Bn-1, and Bn are at grayscale 0 and display no brightness.
[0106] Among them, the last sub-pixel in each row of the second sub-display screen 2 constitutes a column of sub-pixels, and this column of sub-pixels cannot display the picture, which is the third sub-normally black display area; and the second to last sub-pixel and the third to last sub-pixel in each row of the second sub-display screen constitute two columns of sub-pixels, and these two columns of sub-pixels cannot display the picture, which is the fourth sub-normally black display area.
[0107] Figure 3In the embodiment shown, the first sub-display screen 1 and the second sub-display screen 2 are arranged in the vertical direction. For spliced displays with other structures in which the first sub-display screen 1 and the second sub-display screen 2 are arranged in the horizontal direction, the dynamic display area and the normally black display area described in the above embodiments are both applicable.
[0108] like Figure 4 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 4 In the embodiment shown, one pixel includes three sub-pixels; and the first sub-display screen 1 and the second sub-display screen are offset by three sub-pixels, that is, the first sub-display screen 1 and the second sub-display screen 2 are offset by one pixel.
[0109] At this point, the first sub-display screen 1 includes only the first normally-black sub-area, excluding the second normally-black sub-area. This is because, except for the sub-pixels in the first normally-black sub-area, all other sub-pixels in the first sub-display screen 1 form a complete pixel unit and can display images normally. Similarly, the second sub-display screen 2 includes only the third normally-black sub-area, excluding the fourth normally-black sub-area.
[0110] In the embodiments of the present application, regardless of whether the second sub-normally black display area and the fourth sub-normally black display area are included, the number of sub-pixel rows or sub-pixel columns included in the first dynamic display area and the second dynamic display area of the normal display image is a multiple of 3 or 4. When the second sub-normally black display area and the fourth sub-normally black display area are included, the total number of sub-pixel rows or sub-pixel columns included in the fourth sub-normally black display area and the third and fourth normally black display areas is also a multiple of 3 or 4.
[0111] Whether the number of sub-pixel rows or sub-pixel columns is a multiple of 3 or a multiple of 4 depends on whether one pixel includes three sub-pixels or four sub-pixels.
[0112] In the embodiment of the present application, N rows or columns of sub-pixels are offset between the first sub-display screen 1 and the second sub-display screen 2. Thus, the first sub-normally black display area includes N rows or columns of sub-pixels, and the third sub-normally black display area also includes N rows or columns of sub-pixels.
[0113] If the second sub normally black display area includes A rows or A columns of sub-pixels, and the entire second normally black display area includes B rows or B columns of sub-pixels, then A, B, and N satisfy the following condition: B=A+N.
[0114] That is, the total number of sub-pixel rows that do not display an image in the second normally-black display area is equal to the total number of sub-pixel rows in the first sub-normally-black display area plus the total number of sub-pixel rows in the second sub-normally-black display area. In other embodiments, the total number of sub-pixel columns that do not display an image in the second normally-black display area is equal to the total number of sub-pixel columns in the first sub-normally-black display area plus the total number of sub-pixel columns in the second sub-normally-black display area.
[0115] If the second sub-normally black display area is not included, that is, the second sub-normally black display area includes 0 rows or 0 columns of sub-pixels, then A is 0; then the fourth sub-display area is not included in the second normally black display area, and the number of sub-pixel rows or sub-pixel columns in the second normally black display area is equal to the number of sub-pixel rows or sub-pixel columns in the first sub-normally black display area.
[0116] The present application also provides a spliced display including a third sub-display, wherein the third sub-display is filled between the first sub-display 1 and the second sub-display 2. The third sub-display has the same sub-pixel size and number in the first direction as the first sub-display 1 (or the second sub-display 2).
[0117] In the aforementioned embodiment including a third sub-display, when misalignment occurs between the first sub-display 1 and the second sub-display, the third sub-display generally remains fixed relative to one of the sub-displays. Specifically, misalignment between the first sub-display 1 and the second sub-display 2 actually occurs between the third sub-display and one of the sub-displays, while the position of the third sub-display relative to the other sub-display remains fixed.
[0118] Specifically, the third sub-display screen may be aligned with the first sub-display screen 1, and the third sub-display screen may be staggered with the second sub-display screen 2 in the first direction. Furthermore, the third sub-display screen and the second sub-display screen 2 may be staggered by N rows of sub-pixels, or by N columns of sub-pixels.
[0119] The embodiment of the present application also includes a dynamic display area and a normally black display area; however, the dynamic display area and the normally black display area here include a third sub-display screen. For details, please refer to the above description of the dynamic display area and the normally black display area, which will not be repeated here.
[0120] In the embodiments of the present application, the first sub-display screen and the second sub-display screen may be the same or different. When the first sub-display screen and the second sub-display screen are different, one of the sub-display screens may be treated as the third sub-display screen in the aforementioned embodiment; and the third sub-display screen and the first sub-display screen may be treated as a whole.
[0121] Meanwhile, in other embodiments, the spliced display may include more sub-display screens, and the multiple sub-display screens may all be staggered as described in the embodiment of the present application.
[0122] It should be noted that in the embodiments of this application, although N sub-pixels are misaligned between different sub-displays, resulting in a normally black display area where no image can be displayed, since the normally black display area moves to the edge of the entire tiled display, and since the misalignment is only one, two, or three sub-pixels, the resulting normally black display area is very small and generally undetectable to the human eye. Therefore, compared to existing technologies, the image accuracy at the connection between the sub-display and the third sub-display is effectively improved, avoiding problems such as blurring and misalignment.
[0123] The present application also provides a spliced display device, which includes a spliced display as described in any one of the above items. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of a spliced display provided in an embodiment of the present application. Figure 1 In the illustrated embodiment, the tiled display includes at least two sub-displays, including a first sub-display and a second sub-display. The first sub-display and the second sub-display each include sub-pixels arranged in a multi-row and multi-column array. The first sub-display and the second sub-display are staggered in a first direction, with the sub-pixels being offset by N rows or columns.
[0124] At the same time, because the first sub-display screen and the second sub-display screen are offset by N rows of sub-pixels or N columns of sub-pixels in the first direction, the first sub-display screen also includes a first dynamic display screen and a first normally black display area; while the second sub-display screen includes a second dynamic display screen and a second normally black display area. Furthermore, the first dynamic display area and the second dynamic display area include the same sub-pixel rows or sub-pixel columns and have a one-to-one correspondence; the first normally black display area includes a first sub-normally black display area with no corresponding sub-pixels, and the second normally black display area includes a third non-sub-display area with no corresponding sub-pixels.
[0125] The first sub-normally black display area includes N rows of sub-pixels, or the first sub-display area includes N columns of sub-pixels; similarly, the third sub-normally black display area includes N rows of sub-pixels, or the third sub-display area includes N columns of sub-pixels. The first sub-display area and the second sub-display area have different arrangements, and the sub-pixels therein are also different.
[0126] The spliced display device provided in an embodiment of the present application includes at least two sub-displays, including a first sub-display and a second sub-display. The first sub-display, the second sub-display, and the third sub-display have the same sub-pixel size and number in the horizontal or vertical direction. Furthermore, the first sub-display and the second sub-display are offset by N rows or columns of sub-pixels in the horizontal or vertical direction. This spliced display arrangement effectively improves the precision of the moving display by offsetting N sub-pixels and avoids problems such as misalignment and blurring at the junction of the first sub-display and the second sub-display.
[0127] exist Figure 1 In the illustrated embodiment, the first sub-display screen 1 and the second sub-display screen 2 are arranged vertically above each other; specifically, the first sub-display screen 1 is arranged above the second sub-display screen 2. The first and second sub-display screens 1 and 2 have the same sub-pixel size and number in the horizontal direction, and the sub-pixels in the first and second sub-display screens 1 and 2 are offset by N columns in the horizontal direction.
[0128] In this case, the first sub-display screen 1 includes a first dynamic display area and a first normally black display area; while the second sub-display screen 2 correspondingly includes the first dynamic display area and the second normally black display area. The first dynamic display area includes sub-pixels arranged in a multi-row, multi-column array, and the second dynamic display area also includes sub-pixels arranged in a multi-row, multi-column array. The multiple columns of sub-pixels in the first dynamic display area are identical to the multiple columns of sub-pixels in the second dynamic display area, and are arranged in a one-to-one correspondence.
[0129] Among them, the sub-pixels arranged in a multi-row and multi-column array can be red sub-pixels, green sub-pixels and blue sub-pixels, that is, RGB sub-pixels. Typically, the sub-pixels in each row of the sub-display screen are the same, and the sub-pixels in each column (or each row) are arranged crosswise in the order of RGB. In other embodiments of the present application, the sub-pixels arranged in a multi-row and multi-column array can also be red sub-pixels, green sub-pixels, blue sub-pixels and white sub-pixels, that is, RGBW sub-pixels. Similarly, the sub-pixels in each row (or each column) of the sub-display screen are the same, and the sub-pixels in each column (or each row) are arranged crosswise in the order of RGBW.
[0130] exist Figure 1 In the illustrated embodiment, the first normally black display area also includes a second sub-normally black display area, with the second sub-normally black display area and the first sub-normally black display area respectively disposed at opposite ends of the first dynamic display area. Specifically, due to the misalignment between the first sub-display screen and the second sub-display screen, no sub-pixels in the second sub-display screen correspond to the first sub-normally black display area. This means that the first normally black display area includes the first sub-normally black display area facing the empty space. This first sub-normally black display area facing the empty space prevents the first sub-normally black display area from displaying images properly.
[0131] Since a pixel usually includes three or four sub-pixels, the sub-pixel rows / columns contained in the first dynamic display area and the second dynamic display area that can normally display the picture are both multiples of 3 or 4, so that three or four adjacent sub-pixels can form a pixel to normally display the picture.
[0132] When the first sub-normally black display area cannot display the picture normally, the sub-pixels in the second sub-normally black display area cannot form a complete pixel, resulting in the sub-pixels in the second sub-normally black display area also being unable to display the picture normally, making the second sub-normally black display area a normally black display area that cannot display the picture.
[0133] Because the first and second sub-display screens are misaligned, a first normally black display area is generated in the first sub-display screen, and a second normally black display area is generated in the second sub-display screen. The first normally black display area includes a first normally black sub-area facing the blank area, and the second normally black display area also includes a third normally black sub-area facing the blank area.
[0134] Please refer to Figure 1 ,exist Figure 1 In the example, some of the rightmost sub-pixels in the second sub-display have no corresponding pixels in the first sub-display, rendering them unable to display images. Therefore, these sub-pixels form the third sub-normally black display area. The third sub-normally black display area is identical to the first sub-normally black display area in that both are normally black areas facing the empty space. That is, neither the first nor the third sub-normally black display area has a sub-pixel corresponding to it.
[0135] It should be noted that the first normally black display area and the second normally black display area in the embodiment of the present application are both caused by the misalignment between different sub-display screens, and the sub-display screen itself does not include a normally black display area that cannot display an image.
[0136] like Figure 2 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 2 In the embodiment shown, the spliced display also includes a first sub-display screen and a second sub-display screen; Figure 1 The embodiment shown differs in that Figure 2 The first sub-display screen 1 and the second sub-display screen 2 are arranged along the horizontal direction; specifically, the second sub-display screen 2 is arranged on the right side of the first sub-display screen 1.
[0137] At the same time, the sub-pixel size and number of the first sub-display screen 1 and the second sub-display screen 2 in the vertical direction are the same; Figure 2 The first sub-display screen and the second sub-display screen are offset in the vertical direction by N rows of sub-pixels.
[0138] exist Figure 2In the illustrated embodiment, the first sub-display screen 1 also includes a first dynamic display area capable of displaying images, and a first normally black display area incapable of displaying images. Similarly, the second sub-display screen 2 also includes a second dynamic display area capable of displaying images, and a second normally black display area incapable of displaying images.
[0139] at the same time, Figure 2 In the illustrated embodiment, the first normally black display area also includes a first normally black sub-area and a second normally black sub-area; and the second normally black display area includes a third normally black sub-area and a fourth normally black sub-area. Furthermore, the first and second normally black sub-areas are positioned on either side of the first dynamic display area; while the third dynamic display area and the third normally black sub-area are positioned on either side of the fourth normally black sub-area.
[0140] exist Figure 1 and Figure 2 In the illustrated embodiment, no sub-pixels in the second sub-display screen 2 correspond to the first sub-normally black display area, and no sub-pixels in the first sub-display screen 1 correspond to the third sub-normally black display area. Both the first sub-normally black display area and the third sub-normally black display area include N rows or N columns of sub-pixels.
[0141] In an embodiment of the present application, if three sub-pixels constitute a pixel, then when N is 3a-2, the first normally black display area includes 3a-2 rows (or columns) of sub-pixels, and at this time the second sub-normally black display area can include 2 rows (or columns) of sub-pixels.
[0142] Specifically, when the first sub-normally black display area includes 3a-2 rows of sub-pixels, the second sub-normally black display area includes 1 row of sub-pixels; when the first sub-normally black display area includes 3a-1 rows of sub-pixels, the second sub-normally black display area includes 2 rows of sub-pixels; the first sub-normally black display area includes 3a rows of sub-pixels, and the second sub-normally black display area includes 0 rows of sub-pixels.
[0143] Please refer to Figure 1 ,exist Figure 1 In the illustrated embodiment, when a pixel includes three sub-pixels, N can be 1. In this case, the first sub-display screen 1 and the second sub-display screen 2 can be horizontally offset by one column of sub-pixels. In this case, the first sub-normally black display area includes one column of sub-pixels; similarly, the third sub-normally black display area also includes one column of sub-pixels. In this case, the second sub-normally black display area includes 3-1=2 columns of sub-pixels.
[0144] In some other embodiments, the first sub-display screen 1 and the second sub-display screen 2 may be horizontally offset by two columns of sub-pixels. In this case, the first sub-normally black display area includes two columns of sub-pixels. Similarly, the third sub-normally black display area also includes two columns of sub-pixels. The second sub-normally black display area includes 3-2=1 column of sub-pixels.
[0145] The first sub-display screen 1 and the second sub-display screen 2 may also be horizontally offset by three columns of sub-pixels. In this case, the first sub-normally black display area includes three columns of sub-pixels. Similarly, the third sub-normally black display area also includes three columns of sub-pixels. The second sub-normally black display area includes 3-3=0 columns of sub-pixels.
[0146] When N is 2, both the first and second sub-normally black display areas include 4 columns of sub-pixels, but the second sub-normally black display area still includes 2 columns of sub-pixels. Similarly, when N is 2 and the first sub-normally black display area includes 5 columns of sub-pixels, the second sub-normally black display area includes 1 column of sub-pixels. When N is 3, the first sub-normally black display area includes 6 columns of sub-pixels, while the second sub-normally black display area includes 0 columns of sub-pixels.
[0147] In other embodiments of the present application, if a pixel includes four sub-pixels, when the first sub-normally black display area includes 4a-3 rows of sub-pixels, the second sub-normally black display area includes 3 rows of sub-pixels; when the first sub-normally black display area includes 4a-2 rows of sub-pixels, the second sub-normally black display area includes 2 rows of sub-pixels; when the first sub-normally black display area includes 4a-1 rows of sub-pixels, the second sub-normally black display area includes 1 row of sub-pixels; the first sub-normally black display area includes 4a rows of sub-pixels, and the second sub-normally black display area includes 0 rows of sub-pixels.
[0148] Specifically, when N is 1 and the first sub-normally black display area includes one row of sub-pixels, the second sub-normally black display area includes three rows of sub-pixels. When N is 3 and the first sub-normally black display area includes five rows of sub-pixels, the second sub-normally black display area still includes three rows of sub-pixels.
[0149] That is, in an embodiment of the present application, when a pixel includes three sub-pixels, no matter how many rows (or columns) of sub-pixels are offset between the first sub-display screen and the second sub-display screen, the second sub-normally black display area only includes one row of sub-pixels, or two rows of sub-pixels, or zero rows of sub-pixels, that is, there is no second sub-normally black display area.
[0150] Similarly, when a pixel includes four sub-pixels, regardless of the number of rows (or columns) of sub-pixels offset between the first and second sub-display screens, the second sub-normally black display area only includes one row, two rows, three rows, or zero rows of sub-pixels. When the second sub-normally black display area includes a pilot sub-pixel, there is no second sub-normally black display area.
[0151] In the embodiment of the present application, the number of rows or columns of sub-pixels in the first normally black sub-display area is usually the same as the number of rows or columns of sub-pixels in the third non-sub-display area.
[0152] exist Figure 1 and Figure 2In the illustrated embodiment, the first normally black display area includes not only the first normally black sub-area but also the second normally black sub-area. Furthermore, the second normally black display area also includes the third and fourth normally black sub-areas. The second and fourth normally black sub-areas are typically positioned opposite each other.
[0153] When the number of rows or columns of sub-pixels in the first sub-normally black display area is the same as the number of rows or columns of sub-pixels in the third sub-normally black display area; the number of rows or columns in the second sub-normally black display area is usually also the same as the number of rows or columns of sub-pixels in the fourth sub-normally black display area.
[0154] like Figure 3 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 3 In the example, the tiled display includes a first sub-display 1 and a second sub-display 2; each of the first sub-display 1 and the second sub-display 2 is composed of multiple sub-pixels. The multiple sub-pixels can be red pixels, green pixels, and blue pixels, i.e., RGB pixels. Normally, the multiple sub-pixels in the first and second sub-displays are of the same sub-pixel type, for example, all R sub-pixels, while the multiple sub-pixels in the same row are arranged in an interleaved, RGB order.
[0155] exist Figure 3 In the illustrated embodiment, the first sub-display screen 1 and the second sub-display screen 2 are offset by one sub-pixel. The sub-pixels in the portion below the first sub-display screen 1 that connects to the second sub-display screen 2 are sub-pixels A1-An, while the sub-pixels in the portion of the second sub-display screen that connects to the first sub-display screen 1 are sub-pixels B1-Bn.
[0156] When the first sub-display screen 1 and the second sub-display screen 2 are horizontally offset by one sub-pixel, sub-pixels A1, A2, and A3, which originally formed a pixel in the first sub-display screen 1, are offset due to A1. Consequently, sub-pixels A2, A3, and A4 in the first sub-display screen 1 form a new pixel. At this point, the sub-pixel arrangement within a pixel changes from RGB to GBR. In the second sub-display screen 2, sub-pixels B1, B2, and B3 also form the pixel within the second sub-display screen; that is, the pixels are still arranged in RGB order.
[0157] In the above embodiment, among the pixels corresponding to the area connected to the second sub-display screen 2 in the first sub-display screen 1, the first sub-pixel and the last two sub-pixels correspond to grayscale 0 and do not display the image. The same is true for the pixels in other rows of the first sub-display screen, where the first sub-pixel and the last two sub-pixels do not display the image. Figure 3In the left and right sides of the first sub-display screen 1, the three columns corresponding to the first sub-pixel and the last two sub-pixels in each row do not display any image. This is because the last two pixels in each row of the first sub-display screen 1 cannot form a complete pixel, and therefore cannot display any image.
[0158] The first sub-pixel in each row of the first sub-display screen 1 constitutes a column of sub-pixels. This column of sub-pixels cannot display images, and this column of sub-pixels is the first sub-normally black display area. Similarly, the last two sub-pixels in each row of the first sub-display screen constitute two columns of sub-pixels. These two columns of sub-pixels cannot display images, and these two columns of images are the second sub-normally black display area.
[0159] For the second sub-display screen 2, the sub-pixels corresponding to sub-pixels Bn-2 and Bn-1 in the second sub-display screen are An-1 and An. However, sub-pixels An-1 and An cannot form a complete pixel unit, resulting in sub-pixels An-1 and An being unable to display images. Consequently, sub-pixels Bn-2, Bn-1, and Bn in the second sub-display screen 2 are also unable to display images. In other words, sub-pixels Bn-2, Bn-1, and Bn are at grayscale 0 and display no brightness.
[0160] Among them, the last sub-pixel in each row of the second sub-display screen 2 constitutes a column of sub-pixels, and this column of sub-pixels cannot display the picture, which is the third sub-normally black display area; and the second to last sub-pixel and the third to last sub-pixel in each row of the second sub-display screen constitute two columns of sub-pixels, and these two columns of sub-pixels cannot display the picture, which is the fourth sub-normally black display area.
[0161] Figure 3 In the embodiment shown, the first sub-display screen 1 and the second sub-display screen 2 are arranged in the vertical direction. For spliced displays with other structures in which the first sub-display screen 1 and the second sub-display screen 2 are arranged in the horizontal direction, the dynamic display area and the normally black display area described in the above embodiments are both applicable.
[0162] like Figure 4 FIG. 1 is a schematic diagram of another embodiment of the spliced display provided by the embodiment of the present application. Figure 4 In the embodiment shown, one pixel includes three sub-pixels; and the first sub-display screen 1 and the second sub-display screen are offset by three sub-pixels, that is, the first sub-display screen 1 and the second sub-display screen 2 are offset by one pixel.
[0163] At this point, the first sub-display screen 1 includes only the first normally-black sub-area, excluding the second normally-black sub-area. This is because, except for the sub-pixels in the first normally-black sub-area, all other sub-pixels in the first sub-display screen 1 form a complete pixel unit and can display images normally. Similarly, the second sub-display screen 2 includes only the third normally-black sub-area, excluding the fourth normally-black sub-area.
[0164] In the embodiments of the present application, regardless of whether the second sub-normally black display area and the fourth sub-normally black display area are included, the number of sub-pixel rows or sub-pixel columns included in the first dynamic display area and the second dynamic display area of the normal display image is a multiple of 3 or 4. When the second sub-normally black display area and the fourth sub-normally black display area are included, the total number of sub-pixel rows or sub-pixel columns included in the fourth sub-normally black display area and the third and fourth normally black display areas is also a multiple of 3 or 4.
[0165] Whether the number of sub-pixel rows or sub-pixel columns is a multiple of 3 or a multiple of 4 depends on whether one pixel includes three sub-pixels or four sub-pixels.
[0166] In the embodiment of the present application, N rows or columns of sub-pixels are offset between the first sub-display screen 1 and the second sub-display screen 2. Thus, the first sub-normally black display area includes N rows or columns of sub-pixels, and the third sub-normally black display area also includes N rows or columns of sub-pixels.
[0167] If the second sub normally black display area includes A rows or A columns of sub-pixels, and the entire second normally black display area includes B rows or B columns of sub-pixels, then A, B, and N satisfy the following condition: B=A+N.
[0168] That is, the total number of sub-pixel rows that do not display an image in the second normally-black display area is equal to the total number of sub-pixel rows in the first sub-normally-black display area plus the total number of sub-pixel rows in the second sub-normally-black display area. In other embodiments, the total number of sub-pixel columns that do not display an image in the second normally-black display area is equal to the total number of sub-pixel columns in the first sub-normally-black display area plus the total number of sub-pixel columns in the second sub-normally-black display area.
[0169] If the second sub-normally black display area is not included, that is, the second sub-normally black display area includes 0 rows or 0 columns of sub-pixels, then A is 0; then the fourth sub-display area is not included in the second normally black display area, and the number of sub-pixel rows or sub-pixel columns in the second normally black display area is equal to the number of sub-pixel rows or sub-pixel columns in the first sub-normally black display area.
[0170] The present application also provides a spliced display including a third sub-display, wherein the third sub-display is filled between the first sub-display 1 and the second sub-display 2. The third sub-display has the same sub-pixel size and number in the first direction as the first sub-display 1 (or the second sub-display 2).
[0171] In the aforementioned embodiment including a third sub-display, when misalignment occurs between the first sub-display 1 and the second sub-display, the third sub-display generally remains fixed relative to one of the sub-displays. Specifically, misalignment between the first sub-display 1 and the second sub-display 2 actually occurs between the third sub-display and one of the sub-displays, while the position of the third sub-display relative to the other sub-display remains fixed.
[0172] The embodiment of the present application also includes a dynamic display area and a normally black display area; however, the dynamic display area and the normally black display area here include a third sub-display screen. For details, please refer to the above description of the dynamic display area and the normally black display area, which will not be repeated here.
[0173] The embodiment of the present application also provides a spliced display driving method for driving the spliced display as described in any one of the above items. Figure 5 FIG. 1 is a flow chart of an embodiment of a method for driving a spliced display provided by an embodiment of the present application, which may include:
[0174] 51. Obtain an initial video image to be displayed.
[0175] 52. Segment the initial video image into a first segmented image and a second segmented image that match the first sub-display screen and the second sub-display screen.
[0176] 53. Display a normally black image in the first normally black display area and the second normally black display area, and display a first segmented image and a second segmented image in the first dynamic display area and the second dynamic display area, respectively.
[0177] Specifically, since the first sub-display screen and the second sub-display screen display different images, the initial video image needs to be segmented to obtain a first segmented image matching the first sub-display screen and a second segmented image matching the second sub-display screen.
[0178] At the same time, since the first sub-display screen and the second sub-display screen in the embodiment of the present application are offset by N rows of sub-pixels or N columns of sub-pixels in the first direction, each segmented image needs to be moved so that the moved images can be aligned.
[0179] Specifically, the first segmented image can be shifted along a first direction by N rows or columns of sub-pixels to obtain a third segmented image, while the second segmented image remains unchanged. The third segmented image is then used to drive the first sub-display, while the second segmented image drives the third sub-display, so that the image displayed on the first sub-display is aligned with the image displayed on the second sub-display without misalignment.
[0180] In some embodiments of the present application, since the spliced display includes the spliced display as described in any of the above embodiments, the first sub-display screen in the spliced display may include a first dynamic display area, and the second sub-display screen includes a second dynamic display area; and the sub-pixel rows / columns included in the first dynamic display area and the second dynamic display area are the same and one-to-one corresponding.
[0181] At this time, using the third split image to drive the first sub-display screen and using the second split image to drive the second sub-display screen so that the picture displayed on the first sub-display screen and the picture displayed on the second sub-display screen are aligned may include:
[0182] The first dynamic display area is driven by the third segmented image; and the second dynamic display area is driven by the second segmented image, so that the picture displayed on the first sub-display screen is aligned with the picture displayed on the second sub-display screen.
[0183] That is, since the first sub-display screen and the second sub-display screen in the spliced display are misaligned, the images corresponding to the first sub-display screen and the second sub-display screen will also be misaligned compared to the initial ones, but this will in turn align the misaligned images, thereby solving the problem of the original image misalignment.
[0184] In some embodiments of the present application, three sub-pixels constitute one pixel, and the driving method also includes: when N=3a, configuring the first normally black display area to be composed only of the first sub-normally black display area; configuring the second normally black display area to be composed only of the third sub-normally black display area; wherein a is a positive integer.
[0185] In other embodiments, when N≠3a, the first normally black display area is configured to be composed of a first sub-normally black display area and a second sub-normally black display area, and the second sub-normally black display area and the first sub-normally black display area are respectively connected to the two sides of the first dynamic display area; the second normally black display area is configured to be composed of a third sub-normally black display area and a fourth sub-normally black display area, and the fourth sub-normally black display area is connected between the second dynamic display area and the third sub-normally black display area; the fourth sub-normally black display area and the second sub-normally black display area include the same pixel rows / columns.
[0186] When N=3a-2, the second sub-normally black display area is designed to include 2 rows / columns of sub-pixels; when N=3a-1, the second sub-normally black display area is designed to include 1 row / column of sub-pixels.
[0187] In other embodiments, four sub-pixels constitute one pixel, and the spliced screen driving method may further include: when N=4a, configuring the first normally black display area to be composed only of the first sub-normally black display area; configuring the second normally black display area to be composed only of the third sub-normally black display area; wherein a is a positive integer.
[0188] When N≠4a, the first normally black display area is configured to be composed of the first sub-normally black display area and the second sub-normally black display area, and the second sub-normally black display area and the first sub-normally black display area are respectively connected to the two sides of the first dynamic display area; the second normally black display area is configured to be composed of the third sub-normally black display area and the fourth sub-normally black display area, and the fourth sub-normally black display area is connected between the second dynamic display area and the third sub-normally black display area; the fourth sub-normally black display area and the second sub-normally black display area contain the same pixel rows / columns.
[0189] In other embodiments, when N=4a-3, the second sub-normally black display area is designed to include 3 rows / columns of sub-pixels; when N=4a-2, the second sub-normally black display area is designed to include 2 rows / columns of sub-pixels; when N=4a-1, the second sub-normally black display area is designed to include 1 row / column of sub-pixels.
