[0030] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0033] It should also be pointed out that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0034] In addition, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The following is an introduction to the related technologies of this application.

[0036] Figure 1 Schematic diagram of a sub-pixel arrangement. Figure 1 As shown in (a) in the figure, usually, each pixel on the display screen is composed of three primary colors, RGB, and arranged in RGB arrangement. Each color on each pixel is called a sub-pixel. However, evaporation is required in the production process of OLED display screens. If the sub-pixel is too small, the mask production is difficult and the evaporation yield is low. In order to improve the yield, the size of the sub-pixel can only be enlarged to reduce the difficulty of the manufacturing process, but this will reduce the resolution of the screen. Therefore, the SPR algorithm can be used, such as Figure 1 As shown in (b), the RGBG arrangement can achieve the same resolution with fewer sub-pixels. In particular, 6 sub-pixels are required to display 2 pixels in the RGB arrangement, while the RGBG arrangement based on the SPR algorithm only requires 4 sub-pixels. Therefore, the physical sub-pixels of the display screen with the same resolution are reduced by one third after using the SPR algorithm. It should be noted that Figure 1 This is only an illustration of the final arrangement on the pixel circuit. Considering the display effect, the arrangement on the circuit board may be slightly different, such as a diamond arrangement, a diamond-like arrangement, etc.

[0037] It can be understood that based on the three-color principle, it is necessary to borrow colors from the surrounding sub-pixels based on the SPR algorithm. In other words, the essence of the SPR algorithm is to construct color pixels in a shared way by rendering the two sub-pixels in the pixel and multiple borrowed pixels, presenting the required brightness and color, and finally restoring the image information on the OLED panel.

[0038] In recent years, with the development of screen technologies such as high refresh rate and high resolution, user experience has also reached a new level. With the increase in refresh rate, higher requirements are also placed on the battery life of mobile phones. In order to achieve lower power consumption while maintaining a high refresh rate, the low-temperature polycrystalline oxide (LTPO) screen technology makes the available refresh rate range of OLED very wide. At present, LTPO technology can dynamically adjust the screen refresh rate between 1Hz and 120Hz. In order to further reduce power consumption, a local dynamic refresh rate technology is proposed. Different refresh rates can be achieved in different positions of the same frame. Figure 2 FIG. 1 is a schematic diagram of a partial dynamic refresh of a display screen. Figure 2 As shown, in the panel, that is, the display area of ​​the display screen, the upper and lower areas use different refresh rates, the refresh rate of the upper part is 120Hz, and the refresh rate of the lower part is 30Hz. If the panel also uses the SPR algorithm, display abnormalities may occur at the boundary of the refresh area, that is, the junction of 120Hz and 30Hz.

[0039] Figure 3 This is a sub-pixel rendering example. Figure 1 Among them, the sub-pixel R (Red) is marked with dots, the sub-pixel G (Green) is marked with grid patterns, and the sub-pixel B (Blue) is marked with diagonal lines. Figure 3 As shown in (a), the left side is Figure 1 The RGB arrangement shown (real RGB arrangement) shows a rendering of a white dot at the panel coordinate position (4, 5). In this case, the value of sub-pixel R is 255, the value of sub-pixel G is 255, and the value of sub-pixel B is 255. Figure 3 As shown in (b), when the right side is a diamond arrangement, a rendering of a white dot is displayed at the position of the panel coordinates (4, 5). Since the sub-pixels of the diamond arrangement are RG or BG, it is impossible to use a sub-pixel to restore a single white dot in the RGB arrangement. Most SPR algorithms often use up and down, left and right borrowing, that is, borrowing sub-pixels on the right, bottom, and lower right sides to display a single white dot based on these 5 sub-pixels. Among them, the values ​​of the sub-pixels B in the upper left corner and the lower right corner are both 135, the values ​​of the sub-pixels R in the upper right corner and the lower left corner are both 135, and the value of the sub-pixel G in the center is 255.

[0040] Figure 4 This is a sub-pixel rendering example. Figure 2If the first four lines of the panel have a refresh rate of 120Hz, and the last four lines have a refresh rate of 30Hz, then when the position with coordinates (4, 5) changes to a black dot in the next frame, the sub-pixels in the 120Hz refresh area will be refreshed first, while the sub-pixels in the 30Hz refresh area will remain refreshed. Figure 4 In (a), for the RGB arrangement panel, the position with coordinates (4, 5) will directly change to black pixels following the refresh of the 120Hz refresh area. The diamond arrangement displays white pixels using up, down, left, and right color borrowing, such as Figure 4 As shown in (b), since the last row of sub-pixels is in the 30Hz refresh area and the first three rows of sub-pixels are in the 120Hz refresh area, local refresh is adopted. After the first three rows are refreshed to black, the last row remains. One sub-pixel R and one sub-pixel B will be retained in the image, presenting a magenta pixel, causing color abnormality.

[0041] Based on this, the present application provides a display device, method, timing controller and storage medium. For a frame of image to be displayed, the color information of the first sub-pixel after adjustment can be determined according to the position information of the first sub-pixel and the color information of the reference sub-pixel, and then displayed. In this way, the color information of the first sub-pixel can be adjusted according to the position information of the first sub-pixel and the color information of the reference sub-pixel adjacent to the first sub-pixel, which can not only solve the color abnormality problem of the display panel at the junction of different refresh rate areas, but also does not affect the color of other areas, thereby improving the display quality of the image.

[0042] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0043] In one embodiment of the present application, Figure 5 A schematic diagram of the structure of a display device provided in an embodiment of the present application Figure 1 .like Figure 5 As shown, the display device 10 may include a display driving device 101 and a display panel 102 coupled to the display driving device 101; wherein:

[0044] The display driving device 101 is used for obtaining position information of a first sub-pixel in a frame of an image to be displayed; wherein, in the frame of the image to be displayed, there is at least one sub-pixel whose refresh rate is different from the refresh rates of sub-pixels at other positions; according to the position information of the first sub-pixel, obtaining color information of a reference sub-pixel associated with the first sub-pixel; and adjusting the color information of the first sub-pixel according to the position information of the first sub-pixel and the color information of the reference sub-pixel;

[0045] The display panel 102 is used to display the first sub-pixel according to the adjusted color information.

[0046] In the embodiments of the present application, Figure 6 A schematic diagram of a mapping of a display image provided in an embodiment of the present application. Figure 6 (a) shows the arrangement of each sub-pixel in the image to be displayed. Figure 6 (b) is a schematic diagram of the arrangement of actual sub-pixels on the display panel 102, wherein the arrangement of sub-pixels in the display panel 102 may be in an RGBG arrangement. In the embodiment of the present application, the number of sub-pixels G in the RGB arrangement and the RGBG arrangement is the same, so there is no need to process the sub-pixels G. The number of sub-pixels R and sub-pixels B in the RGBG arrangement is half of that in the RGB arrangement, and color borrowing is required for display. Therefore, the first sub-pixel may refer to a sub-pixel in the display panel 102 that needs to be displayed in color, such as sub-pixels R and sub-pixels B.

[0047] It should also be noted that if Figure 6 As shown in (a), the sub-pixels r, g and b in each row of the image to be displayed are numbered respectively. Figure 6 In (b), sub-pixels B and R are numbered together, and sub-pixel G is numbered separately.

[0048] In an embodiment of the present application, the position information may include but is not limited to coordinates, row and column values, etc. In some embodiments, the image is divided into rows and columns, and the coordinate information of each first sub-pixel can be obtained respectively, and the coordinate information is used as the position information of the first sub-pixel. In some embodiments, a two-dimensional coordinate system is established with a vertex of the image, and the row and column values ​​of each first sub-pixel can be obtained respectively, and the row and column values ​​are used as the position information of the first sub-pixel. Exemplarily, the position information of the first sub-pixel may refer to the position of the first sub-pixel in the image to be displayed. Exemplarily, when the first sub-pixel is r22, its position information is Figure 6 The 2nd sub-pixel in the 2nd row in (a).

[0049] It can be understood that since the sub-pixels in the image to be displayed do not correspond to the actual sub-pixel arrangement, when the image to be displayed is displayed on the display panel 102, the image to be displayed needs to be rendered so that the image to be displayed can be displayed completely and normally on the display panel 102.

[0050] In the embodiment of the present application, the reference sub-pixel may be one or more sub-pixels that provide a borrowed color for the first sub-pixel and are adjacent to the first sub-pixel at the position of the image to be displayed. In addition, the color information of the reference sub-pixel may refer to the brightness information corresponding to the reference sub-pixel, or may be other parameters that determine the display effect, such as grayscale value. However, since the correspondence between grayscale and color display is nonlinear, it is necessary to change the calculation method of determining the parameter value of the sub-pixel unit to be displayed in the following steps according to the correspondence. Accordingly, the color information of the first sub-pixel in the following embodiment can refer to this explanation.

[0051] In the embodiment of the present application, the display driving device 101 may refer to the sub-pixel that is finally displayed on the display panel 102 after adjusting the first sub-pixel as the second sub-pixel. The position of the second sub-pixel on the display panel 102 corresponds to the position of the first sub-pixel in the image to be displayed. i,j When the second sub-pixel can be R i,j ; In the first sub-pixel, b in the image to be displayed i,j When the second sub-pixel can be B i,j For example, when the first sub-pixel is r22, the second sub-pixel determined according to the first reference sub-pixel and the first sub-pixel is R22, that is, Figure 6 In (b), in the second row on the display panel 102, the sub-pixel B and the sub-pixel R are numbered sequentially as the second sub-pixel.

[0052] In an embodiment of the present application, the display driving device 101 can determine whether to use the color information of one sub-pixel or the color information of multiple sub-pixels in the reference sub-pixel based on the position information of the first sub-pixel, adjust the color information of the first sub-pixel, determine the color information of the second sub-pixel, and display it on the display panel 102.

[0053] In the embodiment of the present application, the display panel 102 may be an electronic device for displaying images and texts, such as an OLED screen, etc. The arrangement of the multiple sub-pixels on the display panel 102 may be an RGBG arrangement, such as a diamond arrangement or a diamond-like arrangement, etc. The display driving device 101 processes the image to be displayed in sequence through the above embodiments to determine the multiple second sub-pixels, and the display panel 102 displays them at corresponding positions.

[0054] It should be noted that before obtaining the position information of the first sub-pixel, the position information and other data corresponding to each sub-pixel in the current row, including color information, can be stored in a static random access memory (SRAM). After obtaining the position information of the first sub-pixel, the position information of the first reference sub-pixel can be further determined, and then the color information corresponding to the first sub-pixel and the color information corresponding to the first reference sub-pixel in the SRAM can be read.

[0055] The embodiment of the present application provides a display device, which can determine the adjusted color information of the first sub-pixel according to the position information of the first sub-pixel and the color information of the reference sub-pixel for a frame of image to be displayed, and then display it. In this way, the color information of the first sub-pixel can be adjusted according to the position information of the first sub-pixel and the color information of the reference sub-pixel adjacent to the first sub-pixel, which can not only solve the color abnormality problem of the boundary area of ​​the display panel at different refresh rate areas, but also does not affect the color of other areas, thereby improving the display quality of the image.

[0056] In some embodiments, continue to refer to Figure 5 The reference sub-pixels include at least one of the following: a first reference sub-pixel located in the current row where the first sub-pixel is located and adjacent to the first sub-pixel, a second reference sub-pixel located in the previous row of the current row and adjacent to the first sub-pixel, and a third reference sub-pixel.

[0057] It should be noted that the pixel at each coordinate position is usually called a pixel. A pixel is composed of three sub-pixels: R, G, and B. The first reference sub-pixel associated with the first sub-pixel may refer to a sub-pixel at the previous position in the same row as the first sub-pixel in the image to be displayed and having the same color as the first sub-pixel. Figure 6 , the first sub-pixel is r in the image to be displayed i,j When the first reference sub-pixel can be r in the image to be displayed i,j-1 Or, the first sub-pixel is b in the image to be displayed i,j When the first reference sub-pixel can be b in the image to be displayed i,j-1 For example, Figure 6 As shown in (a), when the first sub-pixel is r22, the first reference sub-pixel may be r21.

[0058] In the embodiment of the present application, the second reference sub-pixel may refer to at least one sub-pixel in a row above the first sub-pixel in the image to be displayed, wherein in the image to be displayed, the second reference sub-pixel is vertically adjacent to the first reference sub-pixel and belongs to the same column, and the third reference sub-pixel is vertically adjacent to the first sub-pixel and belongs to the same column. i,jWhen the first reference sub-pixel is r i,j-1 , the second reference sub-pixel is r i-1,j-1 , the third reference sub-pixel is r i-1,j Or, in the first sub-pixel b i,j When the first reference sub-pixel is b i,j-1 , the second reference sub-pixel is b i-1,j-1 , the third reference sub-pixel is b i-1,j Exemplarily, when the first sub-pixel is r22, the first reference sub-pixel may be r21, the second reference sub-pixel may be r11, and the third reference sub-pixel may be r12.

[0059] It should be noted that the row where the first sub-pixel is located may be located in the same refresh area as the rows where the second reference sub-pixel and the third reference sub-pixel are located, or may be located in different refresh areas.

[0060] The embodiment of the present application provides a display device, which determines the adjusted color information of the first sub-pixel according to the position information of the first sub-pixel and the color information of one or more sub-pixels in the reference sub-pixel, and displays it. In this way, the adjusted color information of the first sub-pixel can be determined by one or more of the reference sub-pixels, thereby ensuring the display effect of the image to be displayed, thereby improving the display quality.

[0061] In some embodiments, continue to refer to Figure 5 The display driving device 101 is further used to determine a color adjustment method according to the position information of the first sub-pixel; and adjust the color information of the first sub-pixel based on the color adjustment method and the color information of the reference sub-pixel.

[0062] In the embodiment of the present application, it should be noted that the color adjustment method may include a plurality of color borrowing methods, which can adjust the first sub-pixel based on the reference sub-pixel, and then determine the corresponding second sub-pixel on the display panel 102. Among them, the color borrowing method includes but is not limited to no color borrowing, single-sided color borrowing, double-sided color borrowing, multi-sided color borrowing, etc., and no limitation is made here. It should be understood that when the position of the first sub-pixel is different, the color adjustment method also changes accordingly, so as to avoid the problem of color borrowing from areas with different refresh rates during the adjustment of the color information of the first sub-pixel, causing the display panel 102 to display abnormally after refreshing.

[0063] Further, the display driving device 101 may adjust the color information of the first sub-pixel based on the color information of one or more sub-pixels in the reference sub-pixel based on different color adjustment methods. For example, when the position of the first sub-pixel is close to the positions of other sub-pixels with different refresh rates, the left-right color borrowing method may be adopted, that is, the first sub-pixel is adjusted only based on the reference sub-pixels in the same row as the first sub-pixel in the reference sub-pixels; or, when the position of the first sub-pixel is far from the positions of other sub-pixels with different refresh rates, the up-down-left-right color borrowing method may be adopted, that is, the first sub-pixel is adjusted based on the color information of the sub-pixels in the same row and the adjacent rows of the reference sub-pixel and the first sub-pixel.

[0064] The embodiment of the present application provides a display device, which can use different color processing methods when the first sub-pixel is in different positions, and adjust the first sub-pixel based on the reference sub-pixel. In this way, it is possible to use appropriate color processing methods at different positions, solve the color rendering abnormality problem of the display panel at the boundary position with different refresh rates, and not affect the color rendering of other areas, thereby improving the display quality of the image.

[0065] In some embodiments, continue to refer to Figure 5 The display driving device 101 is further configured to, when the first sub-pixel is in a refresh transition region, determine that the color adjustment method is to adjust the color information of the first sub-pixel based on the first reference sub-pixel; or, when the first sub-pixel is in a non-refresh transition region, determine that the color adjustment method is to adjust the color information of the first sub-pixel based on the first reference sub-pixel, the second reference sub-pixel, and the third reference sub-pixel;

[0066] The refresh transition area is an area where the refresh rate of at least one sub-pixel is different from the refresh rate of other sub-pixels, and the non-refresh transition area is an area of ​​the image to be displayed except the refresh transition area.

[0067] For example, Figure 7 A schematic diagram of the area division of a display panel provided in an embodiment of the present application. Figure 7 As shown, the display panel 102 may include multiple areas with different refresh rates, that is, the display panel 102 may include multiple types of sub-pixels, and the refresh rate of each type of sub-pixel is different from the refresh rate of other types of sub-pixels. Take the connection between the 120Hz refresh area and the 30Hz refresh area as an example, wherein the refresh transition area may include at least one row of sub-pixels at the bottom of the 120Hz refresh area and at least one row of sub-pixels at the top of the 30Hz refresh area, that is, Figure 7The black bold area shown, wherein the refresh transition area includes two types of sub-pixels with different refresh rates, wherein the refresh rate of the location where one type of sub-pixel is located is 120Hz, and the refresh rate of the location where the other type of sub-pixel is located is 30Hz, then the refresh rate of at least one sub-pixel in the refresh transition area is different from the refresh rates of other sub-pixels. That is to say, in an embodiment of the present application, the refresh transition area may include at least one row of sub-pixels at the junction of areas with different refresh rates, and multiple rows of sub-pixels above and below the junction. Among them, it can be understood that the number of rows included in the refresh transition area can be specifically set according to actual display requirements. And, the refresh transition area can also be formed by connecting multiple areas with different refresh rates, then the number of corresponding refresh rates of sub-pixels contained in the refresh transition area has a corresponding relationship with the number of areas.

[0068] In addition, if Figure 7 As shown, the non-refresh transition area may include a first area and a second area, wherein the first area may include an area excluding the boundary of the refresh transition area to the dotted line, such as at least one row of sub-pixels from the top of the refresh transition area to the dotted line position in the 120Hz refresh area, and at least one row of sub-pixels from the bottom of the refresh transition area to the dotted line position in the 30Hz refresh area. The second area refers to the area of ​​the 120Hz refresh area and the 30Hz refresh area excluding the above-mentioned refresh transition area and the first area, that is, Figure 7 As shown, the area from the dotted line position to the upper boundary in the 120 Hz refresh area, and the area from the dotted line position to the lower boundary in the 30 Hz refresh area.

[0069] It should be noted that the above is only an example of each area. For example, the 30Hz refresh area may also intersect with other refresh areas with different refresh rates. The above area division method can be referred to for division below the 30Hz refresh area. The number of rows of sub-pixels contained in each of the above areas can be determined specifically according to rendering requirements.

[0070] In an embodiment of the present application, when the first sub-pixel is in the refresh transition area, in order to avoid borrowing sub-pixels from an area with a different refresh rate from the area where the first area is located, the color adjustment method can be a left-right borrowing method, that is, borrowing sub-pixels in the same row as the first sub-pixel as reference sub-pixels, further adjusting the first sub-pixel, and determining the color information of the second sub-pixel.

[0071] For example, in the embodiment of the present application, when the first sub-pixel is in the refresh transition region, the color adjustment method may be the left-right color borrowing method, and when the second sub-pixel is sub-pixel R, the first reference sub-pixel and the first sub-pixel are also sub-pixel R, and the display driving device 101 determines the color information of the second sub-pixel by the calculation formula shown in the following formula (1):

[0072] Ri,j =f(r i,j-1 ,r i,j ) (1)

[0073] When the color information is a brightness value, f(a,b) is a left-right fusion function, which is used to calculate the average value of the brightness value of parameter a and the brightness value of parameter b. i,j The position of the second sub-pixel is R i,j The corresponding color information, such as brightness value, r i,j-1 is the color information of the first reference sub-pixel, r i,j is the color information of the first sub-pixel.

[0074] Alternatively, when the color adjustment method is the left-right color borrowing method, the second sub-pixel is sub-pixel B, the first reference sub-pixel and the first sub-pixel are also sub-pixel B, and the display driving device 101 determines the color information of the second sub-pixel by the following formula (2):

[0075] B i,j =f(b i,j-1 ,b i,j ) (2)

[0076] When the color information is a brightness value, f(a,b) is a left-right fusion function, which is used to calculate the average value of the brightness value of parameter a and the brightness value of parameter b. i,j The position of the second sub-pixel is B i,j The corresponding color information, such as brightness value, b i,j-1 is the color information of the first reference sub-pixel, b i,j is the color information of the first sub-pixel.

[0077] In this way, based on the above steps, the display driving device 101 can map the first sub-pixel and the first reference sub-pixel in the image to be displayed to the second sub-pixel based on the left-right color borrowing method, and display them on the display panel 102 .

[0078] In the embodiment of the present application, when the first sub-pixel is in the non-refresh transition area, the refresh rates of the sub-pixels in the upper and lower rows are the same as the refresh rate of the first sub-pixel. Therefore, the color adjustment method can be a top-bottom-bottom-left-right color borrowing method, that is, borrowing the sub-pixel in the same row as the first sub-pixel, and the second reference sub-pixel and the third reference sub-pixel in the previous row of the first sub-pixel as reference sub-pixels to further determine the color information of the second sub-pixel. Among them, the display driving device 101 can refer to the above formula (1) or formula (2) to determine the color information of the current row after the left-right color borrowing, and the color information of the previous row after the left-right color borrowing, and combine the color information of the two rows after the left-right color borrowing to determine the color information of the second sub-pixel after the first sub-pixel is adjusted, and display it on the display panel 102, that is, top-bottom-left-right color borrowing.

[0079] It should also be noted that, during specific implementation, those skilled in the art can independently determine the corresponding relationship between the color adjustment method and the color borrowing method according to actual needs, and the embodiments of the present disclosure are not limited thereto.

[0080] In this way, when the first sub-pixel in the image to be displayed is in the refresh transition area, the color information of the first sub-pixel is adjusted according to the color information of the first reference sub-pixel in the same row and adjacent to the first sub-pixel and the color information of the first sub-pixel, and the color information of the second sub-pixel is determined. In this way, when the first sub-pixel is in the refresh transition area, the color information of the second sub-pixel is determined by only referring to the first reference sub-pixel and the first sub-pixel in the same row, without considering the color information of pixels in other rows. This left-right color borrowing method can solve the problem of abnormal color display caused by different refresh rates of different rows in the refresh transition area, that is, at the junction of different refresh rate areas, and improve the display quality of the image.

[0081] The embodiment of the present application provides a display device, which can adjust the color information of the first sub-pixel by using a color adjustment method of borrowing colors from left and right when the first sub-pixel is in a refresh transition area, or adjust the color information of the first sub-pixel by using a color adjustment method of borrowing colors from top to bottom and left to right when the first sub-pixel is in a non-refresh transition area. In this way, this color processing method based on position differentiation can not only solve the color abnormality problem of the display panel in the refresh transition area, but also does not affect the color of the non-refresh transition area, thereby improving the display quality of the image.

[0082] As mentioned above, when the area where the first sub-pixel is located is a refresh transition area and is close to the boundary, the color adjustment method using the upper, lower, left, and right borrowing colors may affect the color of the first sub-pixel. Therefore, the above-mentioned left and right borrowing color scheme is adopted without referring to the data of the upper and lower lines, so the above-mentioned problem will not occur during partial refresh. Figure 4However, the left-right color borrowing scheme does not perform as well as the up-down-left-right color borrowing scheme in some special patterns. Therefore, in order to improve the display quality, the left-right color borrowing scheme in the aforementioned embodiment can be used only at the boundary position in the refresh transition area, and the up-down-left-right color borrowing scheme described below can still be used at other positions.

[0083] In some embodiments, continue to refer to Figure 5 The display driving device 101 is also used to determine the color information of the first target sub-pixel according to the color information of the second reference sub-pixel and the color information of the third reference sub-pixel; determine the color information of the second target sub-pixel according to the color information of the first reference sub-pixel and the color information of the first sub-pixel; and adjust the color information of the first sub-pixel based on the color information of the first target sub-pixel and the color information of the second target sub-pixel.

[0084] In the embodiment of the present application, the position of the first target sub-pixel may correspond to the position of the third reference sub-pixel, and the first target sub-pixel has the same color as the third reference sub-pixel and the second reference sub-pixel. i-1,j When the first target sub-pixel is R i-1,j ; or, when the third reference sub-pixel is b i-1,j When the first target sub-pixel is B i-1,j .

[0085] Since the second reference sub-pixel and the third reference sub-pixel are in the same row, when the first target sub-pixel is sub-pixel R, the display driving device 101 can refer to formula (1) in the above embodiment, based on formula R i-1,j =f(r i-1,j-1 ,r i-1,j ), the color information of the first target sub-pixel is determined by using the left and right color borrowing method, wherein r i-1,j-1 represents the color information of the second reference sub-pixel, r i-1,j represents the color information of the third reference sub-pixel, R i-1,j Indicates the color information of the first target sub-pixel.

[0086] Accordingly, when the first target sub-pixel is sub-pixel B, the display driving device 101 can refer to the above formula (2) and calculate based on formula B: i-1,j =f(b i-1,j-1 ,b i-1,j ), the color information of the first target sub-pixel is determined by borrowing colors from the left and right, where b i-1,j-1 represents the color information of the second reference sub-pixel, b i-1,j represents the color information of the third reference sub-pixel, B i-1,j Indicates the color information of the first target sub-pixel.

[0087] In the embodiment of the present application, the position of the second target sub-pixel may correspond to the position of the first sub-pixel, and the second target sub-pixel has the same color as the first reference sub-pixel and the first sub-pixel. i,j When the second target sub-pixel is R i,j Or, in the first sub-pixel b i,j When the second target sub-pixel is B i,j .

[0088] Therefore, when the second target sub-pixel is sub-pixel R, the display driving device 101 can be based on the above formula (1), that is, R i,j =f(r i,j-1 ,r i,j ), the color information of the second target sub-pixel is determined by borrowing colors from the left and right, where r i,j-1 represents the color information of the first reference sub-pixel, r i,j Represents the color information of the first sub-pixel, R i,j Indicates the color information of the second target sub-pixel.

[0089] When the second target sub-pixel is sub-pixel B, the display driving device 101 can be based on the above formula (2), that is, B i,j =f(b i,j-1 ,b i,j ), the color information of the second target sub-pixel is determined by using the left and right color borrowing method, where b i,j-1 represents the color information of the first reference sub-pixel, b i,j Indicates the color information of the first sub-pixel, B i,j Indicates the color information of the second target sub-pixel.

[0090] Furthermore, based on the color information of the first target sub-pixel and the color information of the second target sub-pixel, the color information corresponding to the left adjacent sub-pixel, the upper adjacent sub-pixel, and the upper left sub-pixel of the first sub-pixel in these two rows can be referred to for vertical fusion, and the color information of the second sub-pixel can be determined by borrowing colors from top to bottom, left to right.

[0091] The embodiment of the present application provides a display device, when the first sub-pixel is in a non-refresh transition area, the display driving device determines the color information of the first target sub-pixel according to the color information corresponding to the second reference sub-pixel and the third reference sub-pixel respectively; determines the color information of the second target sub-pixel according to the color information corresponding to the first reference sub-pixel and the first sub-pixel respectively, and further determines the color information of the second sub-pixel according to the color information of the first target sub-pixel and the second target sub-pixel. In this way, the up, down, left, and right color borrowing is used in the non-refresh transition area, which does not affect the display screen of the image to be displayed, thereby improving the display quality of the image.

[0092] In some embodiments, continue to refer to Figure 5 The display driving device 101 is also used to determine a first weight of a first target sub-pixel and a second weight of a second target sub-pixel; perform weighted calculation according to the first weight, the second weight, the color information of the first target sub-pixel and the color information of the second target sub-pixel to adjust the color information of the first sub-pixel; wherein the distance between the first sub-pixel and the boundary where the refresh rate changes in the refresh transition area is recorded as the first distance; the value of the first weight is directly proportional to the first distance, and the value of the second weight is inversely proportional to the first distance.

[0093] In an embodiment of the present application, the first weight of the first target sub-pixel can be used to characterize the degree of influence of the color information of the first target sub-pixel on the color information of the second sub-pixel; correspondingly, the second weight of the second target sub-pixel can be used to characterize the degree of influence of the color information of the second target sub-pixel on the color information of the second sub-pixel, wherein the sum of the first weight and the second weight is 1.

[0094] In the embodiment of the present application, the coordinates of the boundary positions of each refresh area may be pre-stored as the boundary where the refresh rate changes. After reading the position information of the first sub-pixel, the position of the first sub-pixel may be compared with the boundary to determine the vertical distance between the position of the first sub-pixel and the boundary, which is the first distance.

[0095] Among them, when the first sub-pixel is at different positions in the image to be displayed, that is, the first distance between the first sub-pixel and the junction where the refresh rate changes in the refresh transition area is different, the values ​​of the first weight and the second weight can be made different accordingly. In this way, the influence of the color information of the first target sub-pixel and the color information of the second target sub-pixel on the color information of the second sub-pixel can be adjusted. For example, at the junction, the influence of the first target sub-pixel on the color information of the first sub-pixel can be reduced, so that the color information of the first sub-pixel is determined based on the left and right color borrowing scheme, and the fusion weight is adjusted in other areas. The farther from the junction, the more gradually the influence of the color information of the first target sub-pixel on the color information of the second pixel is increased, and the color information of the second sub-pixel is determined based on the upper, lower, left and right color borrowing scheme.

[0096] Furthermore, the product of the first weight and the color information of the first target sub-pixel and the product of the second weight and the color information of the second target sub-pixel may be added to adjust the color information of the first sub-pixel and determine the color information of the second sub-pixel.

[0097] In the embodiment of the present application, when the second sub-pixel is sub-pixel R, the color information of the second sub-pixel can be determined based on the following formula (3):

[0098] Ri,j =g(f(r i-1,j-1 ,r i-1,j ),f(r i,j-1 ,r i,j )) (3)

[0099] Among them, g(a,b) is the upper and lower fusion function, which is used to calculate the weighted average of parameters a and b, which is interpreted as the product of parameter a and the first weight plus the product of parameter b and the second weight. i,j is the color information of the second sub-pixel, f(r i-1,j-1 ,r i-1,j ) is the color information of the first target sub-pixel, f(r i,j-1 ,r i,j ) color information of the second target sub-pixel.

[0100] Alternatively, when the second sub-pixel is sub-pixel B, the color information of the second sub-pixel may be determined based on the following formula (4):

[0101] B i,j =g(f(b i-1,j-1 ,b i-1,j ),f(b i,j-1 ,b i,j )) (4)

[0102] Among them, B i,j is the color information of the second sub-pixel, f(b i-1,j-1 ,b i-1,j ) is the color information of the first target sub-pixel, f(b i,j-1 ,b i,j ) is the color information of the second target sub-pixel.

[0103] It should be noted that, based on the aforementioned embodiments, when the color adjustment method is the left-right borrowing color method, the second sub-pixel is determined only according to the first sub-pixel and the first reference sub-pixel; when the color adjustment method is the top-bottom-left-right borrowing color method, the second sub-pixel is determined according to the first sub-pixel, the first reference sub-pixel, the second reference sub-pixel and the third reference sub-pixel.

[0104] Alternatively, based on the embodiment of the present application, by adjusting the values ​​of the first weight and the second weight corresponding to different regions, the color adjustment mode can be a left-right color borrowing mode or a top-bottom-left-right color borrowing mode. For example, when the first sub-pixel is in the refresh transition area, the first weight is determined to be equal to 0 and the second weight is equal to 1; when the first sub-pixel is in the first area in the non-refresh transition area, the first distance increases, and the first weight is determined to be 0.25 and the second weight is 0.75; when the first sub-pixel is in the second area in the non-refresh transition area, the first distance increases again, and the first weight is determined to be 0.5 and the second weight is 0.5. In this way, the second target sub-pixel, that is, the sub-pixel that is not in the same row as the first sub-pixel, has a smaller impact on the display effect of the second sub-pixel until it no longer affects the color information of the second sub-pixel. In other words, the smaller the first distance between the first sub-pixel and the junction where the refresh rate changes in the refresh transition area, the smaller the value of the first weight, and the larger the value of the second weight, that is, the value of the first weight is directly proportional to the first distance, and the value of the second weight is inversely proportional to the first distance.

[0105] It can be understood that, in this way, even if the color information of the first target sub-pixel corresponding to the previous row of the first sub-pixel is calculated, since the first weight is 0, the product of the first weight and the color information of the first target sub-pixel is still 0, and the second weight is 1, then the color information of the second sub-pixel is completely dependent on the color information of the second target sub-pixel. When the first sub-pixel is in the refresh boundary area, it is equivalent to determining the color information of the second sub-pixel based only on the aforementioned formula (1) or (2), based only on the color information of the second target sub-pixel, that is, the first reference sub-pixel, and the color information of the first sub-pixel. That is, when the first sub-pixel is located at the preset boundary position, the color information of the second sub-pixel is displayed based on the left and right borrowing color method. In this way, the color information of the second sub-pixel is not affected by the color information of the second reference sub-pixel in the previous row and the color information of the third reference sub-pixel, so when the row where the second reference sub-pixel and the third reference sub-pixel are located is refreshed, it will not affect the display of the second sub-pixel. When the first sub-pixel is in the non-refresh boundary area, the color information of the second sub-pixel is determined based on the above formula (4) or (5), and the color information of the second sub-pixel is determined by referring to the first sub-pixel, the first reference sub-pixel, the second reference sub-pixel and the third reference sub-pixel.

[0106] It should be noted that the above-mentioned numerical values ​​in the present application are only used for exemplary description. In other embodiments of the present application, the first weight and the second weight can also be set to other numerical values ​​to implement this solution. The specific application is reasonably set according to the current situation and no limitation is made here.

[0107] In the embodiment of the present application, the first weight and the second weight can be configured according to the area where the first sub-pixel is located, so that the closer the first sub-pixel is to the junction, that is, the smaller the first distance is, the smaller the first weight is, and the larger the second weight is. Among them, the variation range of the first weight and the second weight can both be [0.5, 1]. The specific correspondence between the setting of the first weight and the second weight and the area where the first sub-pixel is located can refer to the above embodiment, and can also be set according to actual needs.

[0108] The embodiment of the present application provides a display device, which determines a first weight and a second weight, and further performs weighted calculation based on the first weight, the second weight, the color information of the first target sub-pixel, and the color information of the second target sub-pixel to determine the color information of the second sub-pixel. In this way, the display effect of the image to be displayed can be guaranteed and the display quality can be improved by using the color adjustment method of borrowing colors from top to bottom and left to right.

[0109] In some embodiments, continue to refer to Figure 5 , the color information includes at least one of the following: color information corresponding to the red channel, and color information corresponding to the blue channel.

[0110] In the aforementioned embodiment, at least one reference sub-pixel, the first sub-pixel, and the second sub-pixel have the same color and are all sub-pixels R of the red channel, or are all sub-pixels B of the blue channel, then the aforementioned color information may be color information corresponding to the red channel, or color information corresponding to the blue channel.

[0111] As mentioned above, this is because the number of G sub-pixels in the green channel of the RGB arrangement and the RGBG arrangement is the same, so there is no need to process the G pixels, while the number of R sub-pixels and B sub-pixels in the RGBG arrangement is half of that of the RGB arrangement, and color display is required. The SPR algorithm in the related art will have display abnormalities at the boundaries of areas with different refresh rates, and it is necessary to determine the color information of the second sub-pixel based on the steps in the aforementioned embodiments, according to the color information corresponding to at least one reference sub-pixel associated with the first sub-pixel, and the color information of the first sub-pixel.

[0112] In the embodiment of the present application, when the first sub-pixel is a green channel, that is, a sub-pixel G, the color information of the second sub-pixel can be determined based on the following formula (5):

[0113] G i,j =g i,j (5)

[0114] Among them, g i,j is the color information of the first sub-pixel, G i,j is the color information of the second sub-pixel. The above formula (5) can be interpreted as, when the first sub-pixel is the green channel, no matter the first sub-pixel is in Figure 7 In any area of ​​the image, the color information of the first sub-pixel is directly mapped to the color information of the second sub-pixel.

[0115] An embodiment of the present application provides a display device, and the specific implementation of the aforementioned embodiment is elaborated in detail through the above embodiment. It can be seen that according to the technical solution of the aforementioned embodiment, the problem of abnormal color display at the boundary position where the refresh rate changes can be solved, thereby improving the display quality of the image.

[0116] In some embodiments, Figure 8 A schematic diagram of the structure of a display device provided in an embodiment of the present application Figure 2 .like Figure 8 As shown, the display device 10 may further include an external memory 103 .

[0117] Among them, the external memory 103 can be SRAM, a solid state disk (Solid State Disk or Solid State Drive, SSD) or other memory, which is used to store the position information and color information corresponding to each sub-pixel in the row where the first sub-pixel and the first reference sub-pixel are located, and the position information and color information corresponding to each sub-pixel in the row where the second reference sub-pixel and the third reference sub-pixel are located.

[0118] It should be noted that, in the above modules, the display driving device 101 may include a control module 1011, a left and right color borrowing module 1012 and an upper and lower color borrowing module 1013. Among them, the control module 1011 may also be called a spr_mm_ctrl module, which is used to cache the current row data to the SRAM. The left and right color borrowing module 1012 may also be called a spr_h_pro module, including a first left and right color borrowing module a1 and a second left and right color borrowing module a2, wherein the first left and right color borrowing module a1 may also be called a spr_h_pro_mm module, which is used to calculate the color information of the first target sub-pixel corresponding to the previous row, and the second left and right color borrowing module a2 may also be called a spr_h_pro_cur module, which is used to calculate the color information of the second target sub-pixel corresponding to the current row. In this way, the left and right color borrowing part is output through the left and right color borrowing module 1012. In addition, the upper and lower color borrowing module 1013 may also be called a spr_v_pro module, and the output of the left and right color borrowing module 1012 is then passed through the upper and lower color borrowing module 1013 to obtain the RGBG arrangement data of the final output.

[0119] It should also be noted that in the embodiment of the present application, for the display driver 101, in addition to the control module 1011, the left and right borrowing color module 1012 and the upper and lower borrowing color module 1013, the display driver 101 can also include functional modules such as timing control, scan drive and data drive, and the structure of the display driver 101 is not specifically limited here.

[0120] In the embodiments of the present application, Fig. 9 A schematic diagram of an execution flow of a display device provided in an embodiment of the present application. Fig. 9 As shown, the method can be applied to the aforementioned display device 10, and comprises the following steps:

[0121] S201, data of the current row is stored in an external memory.

[0122] In the embodiment of the present application, since the calculation formula requires the use of data from the previous row, the data of the current row, including the position information and color information of each sub-pixel in the current row, needs to be cached to the SRAM each time the current row is processed.

[0123] S202, reading the data of the previous row from the external memory.

[0124] It should be noted that each time the data of the current row is processed, the data of the current row is stored in the SRAM. Thus, when the data of the next row of the current row is processed, the data last stored in the SRAM is used as the data of the previous row.

[0125] It should also be noted that the previous row of data of the first row of data is processed as all 0s.

[0126] S203, determining whether the data is located in a refresh transition area.

[0127] Determine whether the data, i.e., the first sub-pixel, is located in the transition zone, i.e., the refresh transition zone. If it is located in the transition zone, it is necessary to execute step S204, and calculate the weights of the upper and lower data fusion according to the longitudinal distance between the position of the first sub-pixel and the transition zone boundary position, i.e., the preset boundary position, including the first weight and the second weight. Then, according to the aforementioned formulas (3), (4), and (5), based on the first weight and the second weight, calculate the output data of the first sub-pixel, i.e., the color information of the second sub-pixel; if it is located in the non-refresh transition zone, it is necessary to execute step S205, and perform weighted value calculation on the color information of the first target sub-pixel and the color information of the second target sub-pixel to determine the color information of the second sub-pixel.

[0128] S204, calculating the weight of the upper and lower data fusion according to the distance between the position and the boundary position.

[0129] Among them, referring to the aforementioned Figure 7, the first weight and the second weight depend on the distance between the first sub-pixel and the boundary position of the refresh area. The closer the distance to the boundary position, the larger the second weight, and the range of variation is [0.5, 1]. Among them, in the refresh transition area, the first weight corresponding to the previous row of data is 0, and the second weight corresponding to the current row of data is 1; in the first area of ​​the non-refresh transition area, the first weight is 0.25 and the second weight is 0.75; in the second area of ​​the non-refresh transition area, the values ​​of the first weight and the second weight are both 0.5.

[0130] S205, calculate the output data of the current row according to formulas (3), (4), and (5).

[0131] In the embodiments of this application, see Figure 6 In the left-right color borrowing scheme, the calculation method of the sub-pixel R in the RGBG arrangement can refer to the aforementioned formula (1); the calculation method of the sub-pixel B can refer to the aforementioned formula (2); the calculation method of the sub-pixel G can refer to the aforementioned formula (5). In other words, there is no need to process the sub-pixel G, and the calculation of the sub-pixel R and sub-pixel B needs to refer to the values ​​of r and b at their respective positions and the previous position.

[0132] Among them, f(a, b) in formula (1) and formula (2) is a left-right fusion function, which is used to calculate the brightness value of parameter a and the average brightness value of parameter b.

[0133] In the left and right borrowing color scheme, since there is no reference to the data of the upper and lower lines, it will not appear in the local refresh area. Figure 4 However, since the left-right color borrowing scheme does not perform as well as the up-down-left-right color borrowing scheme in some special patterns, the left-right color borrowing scheme is only used at the junction, and the up-down-left-right color borrowing scheme is still used at other locations. Which scheme is used depends on the position of the sub-pixel from the refresh area boundary.

[0134] Among them, in the upper, lower, left, and right color borrowing scheme, the calculation method of sub-pixel R can refer to the above formula (3); the calculation method of sub-pixel B can refer to the above formula (4); the calculation method of sub-pixel G can refer to the above formula (5). Among them, g(a,b) is the upper and lower fusion function, which is used to calculate the weighted average of parameter a and parameter b. The first weight corresponding to parameter a and the second weight corresponding to parameter b can be determined according to the distance between the first sub-pixel and the preset boundary position.

[0135] S206, determining whether it is the last row.

[0136] If it is the last row, continue to execute step S207; if it is not the last row, return to execute step S201 and continue to process the next row as the current row.

[0137] S207, end.

[0138] In another embodiment of the present application, Fig.10 1 is a flow chart of a display method provided in an embodiment of the present application. The display method can be applied to the aforementioned display device 10, such as Figure 5 As shown, the display device 10 includes a display driving device 101 and a display panel 102 coupled to the display driving device 101 . The display panel 102 includes a plurality of sub-pixels arranged in an array.

[0139] like Fig.10 As shown, the display method may include:

[0140] S301 : For a frame of an image to be displayed, obtain position information of a first sub-pixel in the image to be displayed.

[0141] Among them, in a frame of the image to be displayed, there is at least one sub-pixel whose refresh rate is different from the refresh rates of sub-pixels at other positions.

[0142] S302: Acquire color information of a reference sub-pixel associated with the first sub-pixel according to the position information of the first sub-pixel.

[0143] S303, adjusting the color information of the first sub-pixel according to the position information of the first sub-pixel and the color information of the reference sub-pixel, so that the display panel performs display according to the adjusted color information.

[0144] In some embodiments, the reference sub-pixels include at least one of the following: a first reference sub-pixel located in the current row where the first sub-pixel is located and adjacent to the first sub-pixel, a second reference sub-pixel located in the previous row of the current row and adjacent to the first sub-pixel, and a third reference sub-pixel.

[0145] In some embodiments, for the aforementioned step S303, adjusting the color information of the first sub-pixel according to the position information of the first sub-pixel and the color information of the reference sub-pixel may include:

[0146] S401, determining a color adjustment method according to position information of a first sub-pixel.

[0147] S402, adjusting the color information of the first sub-pixel based on the color adjustment method and the color information of the reference sub-pixel.

[0148] In some embodiments, for the aforementioned step S401, determining the color adjustment method based on the position information of the first sub-pixel may include: when the first sub-pixel is in a refresh transition area, determining the color adjustment method is to adjust the color information of the first sub-pixel based on the first reference sub-pixel; or, when the first sub-pixel is in a non-refresh transition area, determining the color adjustment method is to adjust the color information of the first sub-pixel based on the first reference sub-pixel, the second reference sub-pixel and the third reference sub-pixel.

[0149] The refresh transition area is an area where the refresh rate of at least one sub-pixel is different from the refresh rate of other sub-pixels, and the non-refresh transition area is an area of ​​the image to be displayed except the refresh transition area.

[0150] In some embodiments, in the aforementioned step, when the first sub-pixel is in the non-refresh transition region, determining the color adjustment method is to adjust the color information of the first sub-pixel based on the first reference sub-pixel, the second reference sub-pixel, and the third reference sub-pixel may include:

[0151] S501 , determining color information of a first target sub-pixel according to color information of a second reference sub-pixel and color information of a third reference sub-pixel.

[0152] S502 : Determine color information of a second target sub-pixel according to color information of the first reference sub-pixel and color information of the first sub-pixel.

[0153] S503 , adjusting the color information of the first sub-pixel based on the color information of the first target sub-pixel and the color information of the second target sub-pixel.
