[0057] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their detailed descriptions will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0058] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the accompanying drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0059] The terms "a", "an", "the", "said" and "at least one" are used to indicate the existence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and are not a limitation on the quantity of their objects.

[0060] In this application, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium. "And / or" is merely a description of the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0061] The example embodiments of the present disclosure provide a pixel processing method. Referring to Figure 1 as shown, the pixel processing method may include the following steps:

[0062] Step S10, obtain the first pixel density of the first display area of the display device and the second pixel density of the second display area of the display device, and compare the first pixel density and the second pixel density, where the first display area is closer to the edge of the display device than the second display area.

[0063] Step S20, if the second pixel density is greater than the first pixel density, then at the image end, supplement and expand the pixel points in the first mapped image area, or decimate the pixel points in the second mapped image area. The first display area corresponds to and is mapped with the first mapped image area, and the second display area corresponds to and is mapped with the second mapped image area.

[0064] The pixel processing method and pixel processing device of the present disclosure supplement and expand the pixel points in the first mapped image area 71 or decimate the pixel points in the second mapped image area 72 at the image end, so that the pixel density of the first mapped image area 71 is equal to the pixel density of the second mapped image area 72, thereby enabling the content of the first mapped image area 71 and the second mapped image area 72 to be extracted and mapped simultaneously, and further reducing the total number of mapped image pixels in the display system, reducing the occupation of hardware resources, and reducing the volume of the display system.

[0065] This pixel processing method can be applied to an LED display device. Since the display of an LED display device is achieved by converting image information into control information for the LED lights 5, which is a mapping from the image to the LED lights 5, the arrangement of current video sources is all regular rectangles, and controlling whether the LED lights 5 are on or off is achieved through the control of pixel gray levels. For example, the reason an LED light 5 is off is that it is controlled to display as completely black. However, in terms of the occupation of hardware resources, a black screen and a white screen require the same number of pixel points.

[0066] In addition, during the display process of an LED display system, the number of pixel points is superimposed and calculated based on the boundaries of the LED light patterns. And the number of pixel points is closely related to the number of network ports. Usually, the maximum number of pixel points that a single gigabit network port can drive is 650,000 pixel points. LED display is a mapping from image information to the control of LED lights 5. Refer to Figure 2As shown, the conversion from an image to the LED lamp 5 requires converting pixel information such as pictures and videos stored in the playback host 1 into TCP / IP network information through the sending card 2, then receiving it through the receiving card 3, and converting the network information into a control signal for the LED driving circuit 4, and finally converting it into voltage and current control of the LED lamp 5. In this system, there is a conversion from the HDMI interface of the playback host 1 to the image transmission TCP / IP network interface (network port). The HDMI interface has a fixed pixel loading capacity. For example, HDMI 2.0 can play 4K videos, while a single network port can transmit 650,000 pixel points. The increase in the number of pixel points will lead to an increase in the number of network ports, and further will also lead to an increase in the size and number of boards (sending card 2 and receiving card 3), which will result in an increase in the overall volume of the LED display system.

[0067] Of course, this pixel processing method can also be applied to other types of display devices, such as OLED display devices, LCD display devices, and so on.

[0068] This pixel processing method is mainly applicable to special-shaped display devices. Referring to Figure 3 、 Figure 4 and Figure 5 As shown, the special-shaped display device may include a plurality of display units 6, and the plurality of display units 6 are spliced to form a special-shaped display device. The display unit 6 may include a first display area 61 and a second display area 62, and the first display area 61 may also be adjacent to the second display area 62; the first display area 61 may surround the second display area 62. For example, the second display area 62 may be set as a regular hexagon, a rectangle, a circle, or various polygons. Correspondingly, the first display area 61 may be set as a ring of a regular hexagon, a ring of a rectangle, a ring of a circle, or a ring of various polygons, so that the gap between the first display area 61 and the second display area 62 is relatively uniform to achieve a better display effect; of course, in some other exemplary embodiments of the present disclosure, the shape of the first display area 61 may not correspond to the shape of the second display area 62. For example, it may be set that the circular ring-shaped first display area 61 surrounds the rectangular second display area 62.

[0069] Since the first display area 61 and the second display area 62 display different contents and may have different pixel densities, usually, the contents of the first display area 61 and the second display area 62 are separately extracted and pixel points are spliced.

[0070] Since the display of the LED lamp 5 is a mapping from the pixel points of the image to the LED lamp 5, each LED lamp 5 corresponds to each pixel point in the mapped image. Therefore, each display area corresponds to a mapped image area. Specifically, the first display area 61 corresponds to the first mapped image area 71, the second display area 62 corresponds to the second mapped image area 72, the third display area corresponds to the third mapped image area 73, and so on.

[0071] Moreover, for the same image, the spacing between pixel points is fixed, that is, the pixel density is fixed; assuming that the pixel densities of the first display area 61 and the second display area 62 are different, there are two mapping relationships between the first display area 61 and the second display area 62 and the image, and mapping processing needs to be performed separately. Obviously, when performing pixel processing on the first mapped image area 71 corresponding to the first display area 61, the blank area inside the first display area 61, due to the absence of an actual LED lamp 5, is filled with black pixels at the image end (the first mapped image area 71) during the mapping process; similarly, when performing pixel processing on the second display area 62, the blank area outside the second display area 62 is also filled with black pixels at the image end (the second mapped image area 72) during the mapping process due to the absence of an actual LED lamp 5; obviously, this pixel processing method is a waste of the pixel points of the image, and the total number of mapped image pixel points will increase greatly, basically equivalent to twice the actual number of LED lamps 5. When the accumulated number of pixel points is relatively large, more hardware interfaces are required to achieve video transmission to meet the display requirements. However, when the number of hardware interfaces increases, the corresponding number and size of the hardware will also increase, greatly increasing the occupancy of hardware resources.

[0072] The following takes the LED display device as an example to illustrate the pixel processing method of the present disclosure.

[0073] Step S10, obtain the first pixel density of the first display area 61 of the display device and the second pixel density of the second display area 62 of the display device, and compare the first pixel density and the second pixel density. The first display area 61 is closer to the edge of the display device than the second display area 62.

[0074] In the present exemplary embodiment, the pixel density is the number of pixels per inch. The higher the pixel density value, the higher the density at which the display device can display an image, and the higher the degree of realism. The first pixel density is the density of the LEDs in the first display area 61, and the second pixel density is the density of the LEDs in the second display area 62. The determining factor for the pixel density of the LED display device is the spacing between two adjacent LED lights 5. Therefore, the determining factor for the first pixel density of the first display area 61 is the first spacing between two adjacent LED lights 5 in the first display area 61, and the determining factor for the second pixel density of the second display area 62 is the second spacing between two adjacent LED lights 5 in the second display area 62.

[0075] Comparing the first pixel density and the second pixel density can also be comparing the first spacing and the second spacing. The first spacing is inversely proportional to the first pixel density, that is, the larger the first spacing, the smaller the first pixel density; similarly, the second spacing is inversely proportional to the second pixel density, that is, the larger the second spacing, the smaller the second pixel density.

[0076] For example, the first spacing is 8 mm and the second spacing is 4 mm. In this case, assuming that the middle blank area of the first display area 61 is S and is a standard rectangle, when filling this blank area, the maximum number of LED lights 5 that can be filled in this area is S / 64. And since the second spacing of the second display area 62 is 4 mm, the number of LED lights 5 covered in the second display area 62 with an area of S is S / 16. Obviously, the number of LED lights 5 with a second spacing of 4 mm is 4 times the number of LED lights 5 with a first spacing of 8 mm.

[0077] Step S20, if the second pixel density is greater than the first pixel density, then at the image end, supplement and expand the pixel points in the first mapped image area 71, or decimate the pixel points in the second mapped image area 72. The first display area 61 is correspondingly mapped to the first mapped image area 71, and the second display area 62 is correspondingly mapped to the second mapped image area 72.

[0078] It should be noted that since the LED lights 5 of the display device are already fixed and cannot be changed, supplementing and expanding the pixel points or compressing the pixel points refers to pixel processing at the image end, that is, at the software end.

[0079] In the present exemplary embodiment, refer to Figure 4As shown, the second pixel density is greater than the first pixel density, that is, the second pitch is less than the first pitch. In the same area, the number of LED lights 5 in the second display area 62 is larger, and the number of LED lights 5 in the first display area 61 is smaller. If the second mapped image area 72 is directly nested within the first mapped image area 71, not all of the LED lights 5 in the second display area 62 can participate in the display, and the distribution of the participating LED lights 5 is uneven, thus affecting the display effect.

[0080] For this, the pixel points in the first mapped image area 71 can be supplemented and extended, which can include supplementing virtual pixel points in the first mapped image area 71 to make the pixel density of the first mapped image area 71 equal to the pixel density of the second mapped image area 72.

[0081] Specifically, for example, when the first pitch of the first display area 61 is twice the second pitch of the second display area 62, that is, when the first pixel density of the first display area 61 is one-fourth of the second pixel density of the second display area 62, then one virtual pixel point is supplemented and extended between two adjacent pixel points in the first mapped image area 71.

[0082] When the first pitch of the first display area 61 is three times the second pitch of the second display area 62, that is, when the first pixel density of the first display area 61 is one-ninth of the second pixel density of the second display area 62, then two virtual pixel points are supplemented and extended between two adjacent pixel points in the first mapped image area 71.

[0083] Moreover, since there is no corresponding LED light 5 on the display device for the supplemented virtual pixel points to display, the virtual pixel points are controlled to display black.

[0084] In the present exemplary embodiment, the pixel points in the second mapped image area 72 can also be decimated. Specifically, it can include removing a part of the pixel points in the second mapped image area 72 and decimating another part of the pixel points into practical pixel points to make the pixel density of the first mapped image area 71 equal to the pixel density of the second mapped image area 72.

[0085] Only the practical pixel points can be displayed through the LED lights 5, and the removed pixel points will not be displayed through the LED lights 5. Since each LED light 5 of the display device corresponds to each pixel point in the mapped image, in the second display area 62 of the display device, a part of the LED lights 5 will not display the picture; this method is applicable when the requirement for the resolution is not too high. This pixel processing method will reduce the display effect and resolution to a certain extent.

[0086] However, after processing by the above two methods, the pixel points of the first mapped image area 71 and the LED lights 5 of the first display area 61, as well as the pixel points of the second mapped image area 72 and the LED lights 5 of the second display area 62, have the same mapping relationship and can be extracted simultaneously. The second mapped image area 72 can be directly nested within the first mapped image area 71 and mapped simultaneously, so the occupation of hardware resources is relatively small. Of course, if the first display area 61 and the second display area 62 are adjacent, the second mapped image area 72 can be directly spliced to the first mapped image area 71.

[0087] Furthermore, the distance between adjacent two useful pixel points is the same, making the display screen relatively uniform.

[0088] Specifically, for example, when the first distance of the first display area 61 is twice the second distance of the second display area 62, that is, the first pixel density of the first display area 61 is one-fourth of the second pixel density of the second display area 62, then decimation is performed in the second mapped image area 72 according to a ratio of 1:4, that is, one pixel point is extracted from every four pixel points for display, and the other three pixel points are not displayed.

[0089] When the first distance of the first display area 61 is three times the second distance of the second display area 62, that is, the first pixel density of the first display area 61 is one-ninth of the second pixel density of the second display area 62, then decimation is performed in the second mapped image area 72 according to a ratio of 1:9, that is, one pixel point is extracted from every nine pixel points for display, and the other eight pixel points are not displayed.

[0090] Moreover, there are multiple useful pixel points extracted, and the distance between any two adjacent useful pixel points is the same.

[0091] The pixel processing method may further include: referring to Figure 5 As shown, if the second pixel density is equal to or less than the first pixel density, that is, the second distance is equal to or greater than the first distance; within the same area, the number of LED lights 5 in the first display area 61 is larger, and the number of LED lights 5 in the second display area 62 is smaller. Then, the second mapped image area 72 and the first mapped image area 71 adopt the same mapping relationship, that is, the pixel points of the first mapped image area 71 and the LED lights 5 of the first display area 61, as well as the pixel points of the second mapped image area 72 and the LED lights 5 of the second display area 62, have the same mapping relationship. If the second mapped image area 72 is directly spliced with the first mapped image area 71, extraction and mapping processing can be performed simultaneously, and moreover, all the LED lights 5 in the second display area 62 can be displayed; thereby reducing the total number of mapped image pixel points in the display system, reducing the occupation of hardware resources, and reducing the volume of the display system.

[0092] Furthermore, for a display device in which the first display area 61 surrounds the second display area 62, the second mapped image area 72 can be nested within the first mapped image area 71, that is, the pixel points of the second mapped image area 72 are nested within the first mapped image area 71.

[0093] For a display device in which the first display area 61 and the second display area 62 are adjacent to each other, the second mapped image area 72 can be spliced to the first mapped image area 71.

[0094] In some exemplary embodiments of the present disclosure, a vacant pixel point area is provided between the first display area 61 and the second display area 62; the vacant pixel point area is an area where no LED lamp 5 is provided. However, when the pixel points of the image are correspondingly mapped to the LED lamp 5, on the image side, the vacant mapped image area 74 is correspondingly mapped to the vacant pixel point area, and black pixel points are also filled in the vacant mapped image area 74, that is, these filled pixel points are black and these black pixel points are not displayed. However, these black pixel points also occupy hardware resources.

[0095] For this, the pixel processing method may further include: obtaining the shape and position of the first display area 61 and the shape and position of the second display area 62, and determining the vacant pixel point area between the first display area 61 and the second display area 62 according to the shape and position of the first display area 61 and the shape and position of the second display area 62.

[0096] For example, the shape of the first display area 61 and the shape of the second display area 62 can be set to the same isosceles triangle, the position of the first display area 61 and the position of the second display area 62 are adjacent to each other, and moreover, the base of the first display area 61 and the base of the second display area 62 are collinear, so that an isosceles triangle vacant pixel point area is formed between the first display area 61 and the first display area 61.

[0097] Refer to Figure 6 As shown, since the image side is correspondingly mapped to the display area of the display device, therefore, the shape of the first mapped image area 71 and the shape of the second mapped image area 72 can be set to the same isosceles triangle, and the base of the first mapped image area 71 and the base of the second mapped image area 72 are collinear; so that the vacant mapped image area 74 can also be set to an isosceles triangle, and the vacant mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72.

[0098] Refer to Figure 7As shown in the figure, at the image end, the second mapped image area 72 is spliced to the first mapped image area 71. Specifically, after the second mapped image area 72 is rotated, it is spliced to the first mapped image area 71, and the rotation angle is 180 degrees. After the second mapped image area 72 is rotated by 180 degrees, it forms an isosceles triangle that is roughly the same as the vacant mapped image area 74, so that a part of the second mapped image area 72 is located in the vacant mapped image area 74. Therefore, black pixel points do not need to be set in the vacant mapped image area 74, but pixel points of the second mapped image area 72 corresponding to the second display area 62 are set. Pixel points may not be set in the original second mapped image area 72, thereby reducing the total number of mapped image pixel points of the display system, reducing the occupation of hardware resources, and reducing the volume of the display system.

[0099] Furthermore, a plurality of first display areas 61 are provided, a plurality of second display areas 62 are provided, and the plurality of first display areas 61 and the plurality of second display areas 62 are arranged alternately. For example, the shapes of the first display area 61 and the second display area 62 can be set as the same isosceles triangle, the positions of the first display area 61 and the second display area 62 are adjacent, and the bottom sides of the first display area 61 and the second display area 62 are collinear, so that an isosceles triangle vacant pixel point area is formed between the first display area 61 and the first display area 61. The plurality of first display areas 61 and the plurality of second display areas 62 are arranged alternately, that is, a second display area 62 is provided between two adjacent first display areas 61, that is, a first display area 61 is provided between two adjacent second display areas 62.

[0100] Since the image end is correspondingly mapped to the display area of the display device, that is, the first display area 61 is correspondingly mapped to the first mapped image area 71, the second display area 62 is correspondingly mapped to the second mapped image area 72, and the vacant mapped image area 74 is correspondingly mapped to the vacant pixel point area; therefore, referring to Figure 8 As shown in the figure, the shapes of the first mapped image area 71 and the second mapped image area 72 can be set as the same isosceles triangle, the first mapped image area 71 and the second mapped image area 72 are adjacent, and the bottom sides of the first mapped image area 71 and the second mapped image area 72 are collinear; the vacant mapped image area 74 can also be set as an isosceles triangle, and the vacant mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72. The plurality of first mapped image areas 71 and the plurality of second mapped image areas 72 are also arranged alternately, that is, a second mapped image area 72 is provided between two adjacent first mapped image areas 71, and a first mapped image area 71 is provided between two adjacent second mapped image areas 72.

[0101] In this case, after splicing the second mapped image region 72 to the first mapped image region 71, the original second mapped image region 72 forms a vacant region. Refer to Figure 9 As shown, move the first mapped image region 71 adjacent to the second mapped image region 72 to the second mapped image region 72. Of course, the second mapped image region 72 spliced to the first mapped image region 71 also moves accordingly; thus, the second mapped image region 72 can be filled without setting black pixel points; furthermore, the total number of mapped image pixels in the display system is reduced, the occupation of hardware resources is decreased, and the volume of the display system is reduced.

[0102] The above describes the case where the first display region 61 and the second display region 62 form a group of display regions.

[0103] In some other exemplary embodiments of the present disclosure, refer to 10- Figure 13 As shown, it is possible that the first display region 61, the second display region 62, and the third display region form a group of display regions.

[0104] Therefore, the pixel processing method may further include: obtaining the shape and position of the first display region 61, the shape and position of the second display region 62, and the shape and position of the third display region, and determining that there is a vacant pixel region between the first display region 61 and the second display region 62 according to the shape and position of the first display region 61 and the shape and position of the second display region 62, and the third display region is included in the display device.

[0105] For example, the shapes of the first display region 61, the second display region 62, and the third display region can be set to the same isosceles triangle, the positions of the first display region 61, the second display region 62, and the third display region are arranged adjacent to each other in sequence, and moreover, the bases of the first display region 61, the second display region 62, and the third display region are collinear, so that an isosceles triangle vacant pixel region is formed between the first display region 61 and the first display region 61.

[0106] Since the image end is correspondingly mapped to the display area of the display device, that is, the first display area 61 is correspondingly mapped to the first mapped image area 71, the second display area 62 is correspondingly mapped to the second mapped image area 72, the third display area is correspondingly mapped to the third mapped image area 73, and the vacant mapped image area 74 is correspondingly mapped to the vacant pixel area; therefore, as shown in FIG. 10, the shapes of the first mapped image area 71, the second mapped image area 72, and the third mapped image area 73 can be set as the same isosceles triangle. The first mapped image area 71 and the second mapped image area 72 are arranged adjacent to each other. The base of the first mapped image area 71, the base of the second mapped image area 72, and the base of the second mapped image area 72 are collinear. The vacant mapped image area 74 can also be set as an isosceles triangle, and the vacant mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72.

[0107] At the image end, as shown in FIG. 11, the third mapped image area 73 is spliced between the first mapped image area 71 and the second mapped image area 72. Specifically, after the third mapped image area 73 is rotated, it is spliced between the first mapped image area 71 and the second mapped image area 72, and the rotation angle is 180 degrees. After the third mapped image area 73 is rotated by 180 degrees, it forms an isosceles triangle that is substantially the same as the vacant mapped image area 74, so that a part of the third mapped image area 73 is located in the vacant mapped image area 74. Therefore, black pixel points do not need to be set in the vacant mapped image area 74, but pixel points of the third mapped image area 73 corresponding to the third display area are set. Pixel points may not be set in the original third mapped image area 73, thereby reducing the total number of mapped image pixel points of the display system, reducing the occupation of hardware resources, and reducing the volume of the display system.

[0108] Further, a plurality of first display areas 61 are provided, a plurality of second display areas 62 are provided, a plurality of third display areas are provided, and the plurality of first display areas 61, the plurality of second display areas 62 and the plurality of third display areas are arranged alternately. For example, the shapes of the first display area 61, the second display area 62 and the third display area can be set to the same isosceles triangle, the positions of the first display area 61, the second display area 62 and the third display area are arranged adjacent to each other in sequence, and moreover, the bases of the first display area 61, the second display area 62 and the third display area are collinear, so that an isosceles triangle vacant pixel area is formed between the first display area 61 and the first display area 61. The plurality of first display areas 61, the plurality of second display areas 62 and the plurality of third display areas are arranged alternately in sequence. For example, they can be arranged as the first display area 61, the second display area 62, the third display area, the first display area 61, the second display area 62, the third display area.

[0109] Since the image end is correspondingly mapped to the display area of the display device, that is, the first display area 61 is correspondingly mapped to the first mapped image area 71, the second display area 62 is correspondingly mapped to the second mapped image area 72, the third display area is correspondingly mapped to the third mapped image area 73, and the vacant mapped image area 74 is correspondingly mapped to the vacant pixel area; therefore, as shown in FIG. 12, the shapes of the first mapped image area 71, the second mapped image area 72 and the third mapped image area 73 can be set to the same isosceles triangle, the first mapped image area 71 is adjacent to the second mapped image area 72, and the base of the first mapped image area 71, the base of the second mapped image area 72 and the base of the second mapped image area 72 are collinear; the vacant mapped image area 74 can also be set to an isosceles triangle, and the vacant mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72. The plurality of first mapped image areas 71, the plurality of second mapped image areas 72 and the plurality of third mapped image areas 73 are also arranged alternately in sequence. For example, they can be arranged as the first mapped image area 71, the second mapped image area 72, the third mapped image area 73, the first mapped image area 71, the second mapped image area 72, the third mapped image area 73.

[0110] In this case, after splicing the third mapped image region 73 to the first mapped image region 71 and the second mapped image region 72, the original third mapped image region 73 forms a first vacant region. As shown in reference 13, moving the first mapped image region 71 adjacent to the third mapped image region 73 to the third mapped image region 73 can fill the third mapped image region 73 without setting black pixel points; thereby reducing the total number of mapped image pixels in the display system, reducing the occupancy of hardware resources, and reducing the volume of the display system.

[0111] In addition, after moving the first mapped image region 71 adjacent to the third mapped image region 73 to the first vacant region, the original first mapped image region 71 forms a second vacant region. Moving the second mapped image region 72 adjacent to the first mapped image region 71 to the second vacant region can fill the second vacant region without setting black pixel points; thereby reducing the total number of mapped image pixels in the display system, reducing the occupancy of hardware resources, and reducing the volume of the display system.

[0112] It should be noted that the third mapped image region 73 spliced between the first mapped image region 71 and the second mapped image region 72 also needs to move accordingly. In addition, more subsequent mapped image regions are arranged in sequence according to the above rules.

[0113] The above example illustrates that the first display region 61, the second display region 62, and the third display region are set as triangles, and the corresponding first mapped image region 71, second mapped image region 72, and third mapped image region 73 are set as triangles; in other exemplary embodiments of the present disclosure, the first display region 61, the second display region 62, and the third display region can also be set as trapezoids and / or parallelograms. Correspondingly, the first mapped image region 71, the second mapped image region 72, and the third mapped image region 73 are set as trapezoids and / or parallelograms. Moreover, the first display region 61, the second display region 62, and the third display region can be different from each other. Correspondingly, the first mapped image region 71, the second mapped image region 72, and the third mapped image region 73 can also be different from each other.

[0114] In some other exemplary embodiments of the present disclosure, the second mapped image region 72 can be moved and spliced to the first mapped image region 71. Of course, the third mapped image region 73 can be moved and spliced between the first mapped image region 71 and the second mapped image region 72. For example, when the first mapped image region 71 and the second mapped image region 72 are set as parallelograms, the second mapped image region 72 can be moved and spliced to the first mapped image region 71.

[0115] It should be noted that although the steps of the pixel processing method in the present disclosure are described in a specific order in the accompanying drawings, this does not require or imply that these steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step for execution, and / or one step may be decomposed into multiple steps for execution, etc.
