"and/or" is only an association relationship describing an associated object, and indicates that three relationships may exist, for example, a and/or B, and may indicate: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.

The disclosed example embodiment provides a pixel processing method, which may include, as shown in fig. 1, the steps of:

step S10, obtaining a first pixel density of a first display area of a display device and a second pixel density of a second display area of the display device, and comparing the first pixel density and the second pixel density, where the first display area is closer to an edge of the display device than the second display area.

Step S20, if the second pixel density is larger than the first pixel density, complementary expansion is carried out on pixel points in a first mapping image area or pixel points in a second mapping image area are extracted at an image end, the first display area is mapped corresponding to the first mapping image area, and the second display area is mapped corresponding to the second mapping image area.

According to the pixel processing method and the pixel processing device, at the image end, supplementary expansion is carried out on the pixel points in the first mapping image area 71, or the pixel points in the second mapping image area 72 are subjected to snapshot, so that the pixel density of the first mapping image area 71 is equal to the pixel density of the second mapping image area 72, and therefore the content of the first mapping image area 71 and the content of the second mapping image area 72 can be extracted and mapped simultaneously, the total number of mapping image pixel points of a display system is reduced, the occupation of hardware resources is reduced, and the size of the display system is reduced.

The pixel processing method can be applied to an LED display device. Since the display of the LED display device is mapping from image to LED lamp 5 by converting image information into control information for LED lamp 5, the arrangement of the film sources is regular rectangle, and controlling the LED lamp 5 to be on or off is controlled by pixel gray scale, for example: the reason why the LED lamp 5 is not turned on is that the LED lamp 5 is controlled to display full black, but in the occupation situation of hardware resources, the black picture and the white picture need to occupy the same pixel point.

In addition, in the process of displaying of the LED display system, the number of the pixels is superposed and calculated according to the boundary of the LED lamp graph. The number of the pixel points is related to the number of the network ports, generally, the number of the pixel points which can be carried by a single gigabit network port is 65 ten thousand pixel points, the LED display is a mapping from image information to the control of the LED lamp 5, as shown in fig. 2, the conversion from the image to the LED lamp 5 requires that the pixel information such as pictures and videos stored in the play host 1 is converted into TCP/IP network information through the sending card 2, then the TCP/IP network information is received through the receiving card 3, the network information is converted into a control signal for the LED driving circuit 4, and finally the voltage and current control of the LED lamp 5 is converted. In the system, the conversion from the HDMI of the playback host 1 to the TCP/IP network interface (portal) for image transmission is performed, the HDMI has a fixed pixel loading number, for example, HDMI2.0 can play 4K video, and a single portal can transmit 65 ten thousand pixels. The increase in the number of pixels will increase the number of network ports, and further increase the size and number of board cards (the transmitting card 2 and the receiving card 3), which will increase the overall size of the LED display system.

Of course, the pixel processing method can also be applied to other types of display devices, such as OLED display devices, LCD display devices, and the like.

The pixel processing method is mainly suitable for the special-shaped display device, and as shown in fig. 3, 4 and 5, the special-shaped display device can comprise a plurality of display units 6, and the plurality of display units 6 are spliced to form the 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 disposed adjacent to the second display area 62; the first display region 61 may be enclosed outside the second display region 62, for example, the second display region 62 may be configured as a regular hexagon, a rectangle, a circle, or various polygons, and correspondingly, the first display region 61 may be configured as a regular hexagon ring, a rectangle ring, a circle ring, or various polygon rings, so that a gap between the first display region 61 and the second display region 62 is relatively uniform, so as to achieve a better display effect; of course, in some other exemplary embodiments of the present disclosure, the shape of the first display region 61 and the shape of the second display region 62 may not correspond, for example, a circular ring-shaped first display region 61 is provided so as to surround a rectangular second display region 62.

Since the first display region 61 and the second display region 62 display different contents in two parts and may have different pixel densities, for this reason, usually, the content of the first display area 61 and the content of the second display area 62 are extracted separately, and pixels are connected.

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

Moreover, for the same image, the distance between the pixel points is fixed, namely the pixel density is fixed; if the pixel densities of the first display area 61 and the second display area 62 are different, two mapping relationships exist between the first display area 61 and the image and between the second display area 62 and the image, and the mapping process needs to be performed separately. Obviously, when the first mapping image area 71 corresponding to the first display area 61 is subjected to pixel processing, the blank area inside the first display area 61 is filled with black pixels at the image end (the first mapping image area 71) during mapping due to the absence of the actual LED lamp 5; similarly, when the second display area 62 is subjected to pixel processing, the blank area at the periphery of the second display area 62 is filled with black pixels at the image end (second mapping image area 72) during mapping since there is no actual LED lamp 5; obviously, the pixel processing mode wastes pixel points of the image, and the total number of the pixel points of the mapping image is greatly increased, which is basically equal to twice of that of the actual LED lamp 5. When the number of pixels calculated accumulatively is large, more hardware interfaces are needed to transmit the video in order to meet the display requirement. However, when the number of interfaces of the hardware is increased, the number, size, and the like of the hardware are correspondingly increased, which greatly increases the occupation of hardware resources.

The following will exemplify the pixel processing method of the present disclosure by taking an LED display device as an example.

Step S10, obtaining a first pixel density of a first display area 61 of a display device and a second pixel density of a second display area 62 of the display device, and comparing the first pixel density and the second pixel density, wherein the first display area 61 is closer to an edge of the display device than the second display area 62.

In the present exemplary embodiment, the pixel density is the number of pixels possessed per inch. The higher the pixel density value, i.e. representing that the display device is capable of displaying images with a higher density, the higher the fidelity. The first pixel density is the density of the LEDs in the first display region 61 and the second pixel density is the density of the LEDs in the second display region 62. The determining factor of the pixel density of the LED display device is the distance between two adjacent LED lamps 5, and therefore, the determining factor of the first pixel density of the first display region 61 is the first distance between two adjacent LED lamps 5 in the first display region 61, and the determining factor of the second pixel density of the second display region 62 is the second distance between two adjacent LED lamps 5 in the second display region 62.

The first pixel density and the second pixel density are compared, or the first pitch and the second pitch are compared. The first distance is inversely proportional to the first pixel density, namely the larger the first distance is, the smaller the first pixel density is; likewise, the second pitch is inversely proportional to the second pixel density, i.e., the greater the second pitch, the less the second pixel density.

For example, the first pitch is 8mm, the second pitch is 4mm, in this case, assuming that the central blank area of the first display region 61 is S and is a standard rectangle, when filling is to be performed in the blank area, the number of LED lamps 5 that can be filled in the area is at most S/64. Since the second pitch of the second display region 62 is 4mm, the number of the LED lamps 5 covered in the second display region 62 having the area S is S/16. Obviously, the number of LED lamps 5 with the second pitch of 4mm is 4 times the number of LED lamps 5 with the first pitch of 8 mm.

Step S20, if the second pixel density is greater than the first pixel density, performing supplemental expansion on the pixel points in the first mapping image region 71 or performing snapshot on the pixel points in the second mapping image region 72 at the image end, where the first display region 61 is mapped corresponding to the first mapping image region 71, and the second display region 62 is mapped corresponding to the second mapping image region 72.

It should be noted that, since the LED lamp 5 of the display device is already fixed and cannot be changed, performing supplemental expansion or compression on the pixel points refers to pixel processing performed on the image side, that is, on the software side.

In the present exemplary embodiment, as shown with reference to fig. 4, the second pixel density is greater than the first pixel density, i.e., the second pitch is smaller than the first pitch. In the same area, the number of LED lamps 5 in the second display region 62 is larger, and the number of LED lamps 5 in the first display region 61 is smaller. If the second mapping image area 72 is directly nested in the first mapping image area 71, the LED lamps 5 in the second display area 62 cannot participate in the display, and the distribution of the LED lamps 5 participating in the display is not uniform, thereby affecting the display effect.

In this regard, the complementary expansion of the pixels in the first mapped image region 71 may include the complementary expansion of the dummy pixels in the first mapped image region 71 such that the pixel density of the first mapped image region 71 is equal to the pixel density of the second mapped image region 72.

Specifically, for example, when the first pitch of the first display region 61 is twice the second pitch of the second display region 62, that is, the first pixel density of the first display region 61 is one-fourth of the second pixel density of the second display region 62, a dummy pixel is additionally extended between two adjacent pixels in the first mapping image region 71.

When the first pitch of the first display region 61 is three times the second pitch of the second display region 62, that is, the first pixel density of the first display region 61 is one ninth of the second pixel density of the second display region 62, two dummy pixels are additionally extended between two adjacent pixels in the first mapping image region 71.

Moreover, since the supplemented dummy pixels are displayed on the display device without the LED lamp 5 corresponding thereto, the dummy pixels are controlled to be displayed in black.

In this exemplary embodiment, the snapshot of the pixels in the second mapping image region 72 may further be performed, specifically, the snapshot may include removing a part of the pixels in the second mapping image region 72, and the snapshot of another part of the pixels is a practical pixel, so that the pixel density of the first mapping image region 71 is equal to the pixel density of the second mapping image region 72.

The practical pixel points can be displayed through the LED lamp 5, the removed pixel points can not be displayed through the LED lamp 5, and because each LED lamp 5 of the display device corresponds to each pixel point in the mapping image, namely, in the second display area 62 of the display device, a part of the LED lamps 5 can not display the picture; this method is suitable for use where the resolution requirements are not too high. The pixel processing method may reduce the display effect and the resolution to some extent.

However, the pixel points of the first mapped image area 71 and the LED lamps 5 of the first display area 61 and the pixel points of the second mapped image area 72 and the LED lamps 5 of the second display area 62 are in the same mapping relationship after the above two methods, and the second mapped image area 72 can be directly embedded in the first mapped image area 71 and the mapping process can be performed at the same time, so that the occupation of hardware resources is small. Of course, if the first display area 61 and the second display area 62 are adjacently disposed, the second mapping image area 72 is directly stitched to the first mapping image area 71.

Furthermore, the distance between two adjacent practical pixel points is the same, so that the display picture is uniform.

For example, when the first pitch of the first display region 61 is twice the second pitch of the second display region 62, that is, the first pixel density of the first display region 61 is one-fourth of the second pixel density of the second display region 62, the ratio of the first pixel density to the second pixel density in the second mapping image region 72 is 1: and 4, performing snapshot in proportion, namely extracting one pixel from the four pixels for display, and not displaying other three pixels.

When the first pitch of the first display region 61 is three times the second pitch of the second display region 62, i.e., the first pixel density of the first display region 61 is one ninth of the second pixel density of the second display region 62, then the ratio of the first pixel density to the second pixel density of the second display region 62 in the second mapped image region 72 is 1: and 9, performing snapshot in proportion, namely extracting one pixel from nine pixels for display, and not displaying other eight pixels.

Moreover, the extracted practical pixel points are multiple, and the distance between any two adjacent practical pixel points is the same.

The pixel processing method may further include: referring to fig. 5, if the second pixel density is equal to or less than the first pixel density, that is, the second pitch is equal to or greater than the first pitch; in the same area, the number of LED lamps 5 in the first display region 61 is larger, and the number of LED lamps 5 in the second display region 62 is smaller. If the second mapping image area 72 and the first mapping image area 71 are directly spliced with the first mapping image area 71, the extraction and mapping processes can be simultaneously performed, and the LED lamps 5 of the second display area 62 can be completely displayed, if the pixel points of the first mapping image area 71 and the LED lamps 5 of the first display area 61 and the pixel points of the second mapping image area 72 and the LED lamps 5 of the second display area 62 are in the same mapping relationship; and further, the number of the total mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the size of the display system is reduced.

Further, for display devices in which the first display region 61 surrounds the second display region 62, the second mapped image region 72 may be nested within the first mapped image region 71, i.e. pixels of the second mapped image region 72 may be nested within the first mapped image region 71.

For display devices where the first display area 61 is disposed adjacent to the second display area 62, the second mapped image area 72 may be stitched to the first mapped image area 71.

In some example embodiments of the present disclosure, a blank pixel point region is provided between the first display region 61 and the second display region 62; the empty space pixel point region is a region where the LED lamp 5 is not set, but when the pixel point of the image is mapped correspondingly to the LED lamp 5, at the image end, the empty space mapping image region 74 is mapped correspondingly to the empty space pixel point region, and black pixel points are also filled in the empty space mapping image region 74, that is, the filled pixel points are black, and the black pixel points are not displayed. However, these black pixels also occupy hardware resources.

For this, the pixel processing method may further include: the shape and position of the first display region 61 and the shape and position of the second display region 62 are acquired, and a blank pixel point region between the first display region 61 and the second display region 62 is determined according to the shape and position of the first display region 61 and the shape and position of the second display region 62.

For example, the shape of the first display region 61 and the shape of the second display region 62 may be provided as the same isosceles triangle, the position of the first display region 61 and the position of the second display region 62 are adjacently provided, and moreover, the base of the first display region 61 is collinear with the base of the second display region 62, so that a blank pixel point region of an isosceles triangle is formed between the first display region 61 and the first display region 61.

Referring to fig. 6, since the image side is mapped corresponding to the display area of the display device, the shape of the first mapping image area 71 and the shape of the second mapping image area 72 may be set to be the same isosceles triangle, and the base of the first mapping image area 71 is collinear with the base of the second mapping image area 72; so that the space-mapped image area 74 can also be arranged as an isosceles triangle and the space-mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72.

Referring to fig. 7, at the image side, the second mapping image area 72 is spliced to the first mapping image area 71, specifically, the second mapping image area 72 is rotated and then spliced to the first mapping image area 71, and the rotation angle is 180 degrees. The second mapped image region 72 is rotated by 180 degrees to form substantially the same isosceles triangle as the space-mapped image region 74 such that a portion of the second mapped image region 72 is located in the space-mapped image region 74, and therefore, it is not necessary to set black pixels in the space-mapped image region 74, but rather, pixels of the second mapped image region 72 corresponding to the second display region 62 are set. And no pixel point can be set in the original second mapping image area 72, so that the number of the total mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the volume of the display system is reduced.

Further, the first display region 61 is provided in plurality, the second display region 62 is provided in plurality, and the plurality of first display regions 61 and the plurality of second display regions 62 are alternately arranged. For example, the shape of the first display region 61 and the shape of the second display region 62 may be provided as the same isosceles triangle, the position of the first display region 61 and the position of the second display region 62 are adjacently provided, and the base of the first display region 61 and the base of the second display region 62 are collinear, so that a blank pixel point region of an isosceles triangle is formed between the first display region 61 and the first display region 61. The plurality of first display regions 61 and the plurality of second display regions 62 are alternately arranged, that is, one second display region 62 is disposed between two adjacent first display regions 61, that is, one first display region 61 is disposed between two adjacent second display regions 62.

Since the image side is mapped correspondingly to the display region of the display device, i.e. the first display region 61 is mapped correspondingly to the first mapped image region 71, the second display region 62 is mapped correspondingly to the second mapped image region 72, and the blank mapped image region 74 is mapped correspondingly to the blank pixel point region; therefore, as shown in fig. 8, the shape of the first mapping image area 71 and the shape of the second mapping image area 72 may be set to be the same isosceles triangle, the first mapping image area 71 is disposed adjacent to the second mapping image area 72, and the base of the first mapping image area 71 is collinear with the base of the second mapping image area 72; the space-mapped image areas 74 may also be arranged as isosceles triangles and the space-mapped image areas 74 are located between the first and second mapped

image areas

71, 72. The plurality of first mapping image areas 71 and the plurality of second mapping image areas 72 are also arranged alternately, that is, one second mapping image area 72 is disposed between two adjacent first mapping image areas 71, and one first mapping image area 71 is disposed between two adjacent second mapping image areas 72.

In this case, after the second mapped image region 72 is merged with the first mapped image region 71, the original second mapped image region 72 is formed into a blank region, and as shown in fig. 9, the first mapped image region 71 adjacent to the second mapped image region 72 is moved to the second mapped image region 72, and of course, the second mapped image region 72 merged with the first mapped image region 71 is also moved; this second mapped image region 72 can thus be filled without the need to set black pixels; and further, the number of the total mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the size of the display system is reduced.

The above explains the case where the first display region 61 and the second display region 62 are formed as a set of display regions.

In other example embodiments of the present disclosure, as shown with reference to fig. 10 to 13, it is possible that the first display region 61, the second display region 62, and the third display region are formed as a set of display regions.

Therefore, the pixel processing method may further include: 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 are acquired, and a vacant pixel point region provided between the first display region 61 and the second display region 62 is determined 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.

For example, the shape of the first display region 61, the shape of the second display region 62, and the shape of the third display region may be provided as the same isosceles triangle, the position of the first display region 61, the position of the second display region 62, and the position of the third display region are disposed adjacently in this order, and the base of the first display region 61, the base of the second display region 62, and the base of the third display region are collinear, so that a blank pixel point region of an isosceles triangle is formed between the first display region 61 and the first display region 61.

Since the image side is mapped correspondingly to the display region of the display device, i.e. the first display region 61 is mapped correspondingly to the first mapped image region 71, the second display region 62 is mapped correspondingly to the second mapped image region 72, the third display region is mapped correspondingly to the third mapped image region 73, and the blank mapped image region 74 is mapped correspondingly to the blank pixel region; therefore, as shown with reference to fig. 10, the shape of the first mapping image region 71, the shape of the second mapping image region 72, and the shape of the third mapping image region 73 may be set to be the same isosceles triangle, the first mapping image region 71 is disposed adjacent to the second mapping image region 72, the base of the first mapping image region 71 is collinear with the base of the second mapping image region 72 and the base of the second mapping image region 72, the space position mapping image region 74 may be set to be an isosceles triangle, and the space position mapping image region 74 is located between the first mapping image region 71 and the second mapping image region 72.

On the image side, as shown in fig. 11, the third mapping image region 73 is spliced between the first mapping image region 71 and the second mapping image region 72, specifically, the third mapping image region 73 is rotated and then spliced between the first mapping image region 71 and the second mapping image region 72, and the rotation angle is 180 degrees. The third mapped image region 73 is rotated by 180 degrees to form an isosceles triangle substantially identical to the space mapped image region 74 such that a part of the third mapped image region 73 is located in the space mapped image region 74, and therefore, it is not necessary to set black pixels in the space mapped image region 74, but rather, pixels of the third mapped image region 73 corresponding to the third display region are set. Pixel points are not required to be set in the original third mapping image region 73, so that the number of the total mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the volume of the display system is reduced.

Further, the first display region 61 is provided in plurality, the second display region 62 is provided in plurality, the third display region is provided in plurality, and the plurality of first display regions 61, the plurality of second display regions 62 and the plurality of third display regions are alternately arranged. For example, the shape of the first display region 61, the shape of the second display region 62, and the shape of the third display region may be provided as the same isosceles triangle, the position of the first display region 61, the position of the second display region 62, and the position of the third display region are adjacently provided in this order, and the base of the first display region 61, the base of the second display region 62, and the base of the third display region are collinear, so that a blank pixel point region of an isosceles triangle is formed between the first display region 61 and the first display region 61. The plurality of first display regions 61, the plurality of second display regions 62, and the plurality of third display regions are alternately arranged in sequence, for example, the first display regions 61, the second display regions 62, the third display regions, the first display regions 61, the second display regions 62, and the third display regions may be arranged.

Since the image side is mapped correspondingly to the display region of the display device, i.e. the first display region 61 is mapped correspondingly to the first mapped image region 71, the second display region 62 is mapped correspondingly to the second mapped image region 72, the third display region is mapped correspondingly to the third mapped image region 73, and the blank mapped image region 74 is mapped correspondingly to the blank pixel region; therefore, as shown in fig. 12, the shape of the first mapping image area 71 and the shape of the second mapping image area 72 and the shape of the third mapping image area 73 may be set to be the same isosceles triangle, the first mapping image area 71 is disposed adjacent to the second mapping image area 72, and the base of the first mapping image area 71 is collinear with the base of the second mapping image area 72 and the base of the second mapping image area 72; the space position mapped image area 74 may be arranged as an isosceles triangle and the space position mapped image area 74 is located between the first mapped image area 71 and the second mapped image area 72. The plurality of first mapping image regions 71, the plurality of second mapping image regions 72, and the plurality of third mapping image regions 73 are also alternately arranged in this order, and for example, the first mapping image regions 71, the second mapping image regions 72, the third mapping image regions 73, the first mapping image regions 71, the second mapping image regions 72, and the third mapping image regions 73 may be arranged.

In this case, after the third mapped image region 73 is spliced to the first mapped image region 71 and the second mapped image region 72, the original third mapped image region 73 is formed into a first empty region, and as shown in fig. 13, the first mapped image region 71 adjacent to the third mapped image region 73 is moved to the third mapped image region 73, whereby the third mapped image region 73 can be filled without setting black pixels; and further, the number of the total mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the size of the display system is reduced.

In addition, after the first mapping image region 71 adjacent to the third mapping image region 73 is moved to the first vacant region, the original first mapping image region 71 is formed to form a second vacant region, and the second mapping image region 72 adjacent to the first mapping image region 71 is moved to the second vacant region, so that the second vacant region can be filled without setting black pixels; and the total number of mapping image pixel points of the display system is reduced, the occupation of hardware resources is reduced, and the volume of the display system is reduced.

It should be noted that the third mapping image region 73 which is stitched between the first mapping image region 71 and the second mapping image region 72 also needs to move following. In addition, more subsequent mapping image areas are sequentially arranged in a moving mode according to the rule.

It has been exemplified above that the first display area 61, the second display area 62 and the third display area are set to be triangular, and the corresponding first mapping image area 71, the second mapping image area 72 and the third mapping image area 73 are set to be triangular; in other example embodiments of the present disclosure, the first display region 61, the second display region 62, and the third display region may also be disposed as a trapezoid and/or a parallelogram, and correspondingly, the first mapping image region 71, the second mapping image region 72, and the third mapping image region 73 are disposed as a trapezoid and/or a parallelogram. The first display area 61, the second display area 62, and the third display area may be different from each other, and the first mapping image area 71, the second mapping image area 72, and the third mapping image area 73 may be different from each other.

In some other exemplary embodiments of the present disclosure, the second mapping image area 72 may be moved and then spliced to the first mapping image area 71. Of course, the third mapped image area 73 may be moved and then stitched between the first mapped image area 71 and the second mapped image area 72. For example, in the case where the first and second mapped

image regions

71 and 72 are set to be parallelograms, the second mapped image region 72 may be moved and then stitched to the first mapped image region 71.

Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken into multiple step executions, etc.
