Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display panel. The display panel 10 may be an OLED display panel, a Micro-LED display panel, or the like; in order to achieve the full-screen effect, the display panel 10 includes a display interface, and the display interface includes a first display area 100 (also referred to as a sub-screen display area) and a second display area 102 (also referred to as a main-screen display area) that are adjacently disposed, where the first display area 100 is used to correspond to a position of a photosensitive element (e.g., an off-screen camera, etc.). Alternatively, the second display region 102 may be surrounded on the periphery of the first display region 100. And the shape of the orthographic projection of the first display area 100 on the display surface of the display panel 10 may be a circle, an ellipse, a rounded rectangle, etc., which is not limited in this application. Further, in order to ensure the photosensitive effect of the photosensitive element, the light transmittance of the first display area 100 is greater than that of the second display area 102.

However, this method may cause the second display area 102 and the first display area 100 to have different brightness when the display panel 10 displays a pure color picture, and a boundary visible to the naked eye exists between the second display area 102 and the first display area 100.

In order to solve the above technical problems and to facilitate understanding, a debugging process of the display panel 10 before factory shipment is first described below; referring to fig. 2, fig. 2 is a schematic flowchart illustrating an embodiment of an image display method according to the present application, the image display method specifically includes:

s101: when a preset gray scale image is displayed on a display interface, a first gray scale of the first display area 100 and a second gray scale of the second display area 102 are obtained; the first display area 100 and the second display area 102 are disposed adjacent to each other, the transmittance of the first display area 100 is greater than that of the second display area 102, and a boundary 1000 is defined between the first display area 100 and the second display area 102.

Specifically, generally speaking, the display panel has a gray scale of 0-255, the maximum brightness of a small-sized display panel can reach 500nits, and the maximum brightness of a display panel for some special industry applications can reach 1500nits, so that one gray scale generally corresponds to one brightness range. The implementation process of the step S101 may be: obtaining target brightness of a preset gray scale image, and obtaining a gray scale corresponding to brightness closest to the target brightness from stored gray scale data of the first display area 100 based on the target brightness, namely the first gray scale; and obtaining a gray scale corresponding to the brightness closest to the target brightness from the stored gray scale data of the second display area 102 based on the target brightness, namely the second gray scale.

In an embodiment, a specific implementation process of the step S101 may be: the display interface is placed in a preset two-dimensional coordinate system, for example, the display interface may be rectangular, a certain corner of the display interface coincides with an origin of the two-dimensional coordinate system, and two adjacent sides of the display interface coincide with coordinate axes of the two-dimensional coordinate system respectively. Then, based on the position information of the first display area 100 and the second display area 102 in the display panel 10 in the design stage, the coordinate information of the first display area 100 and the second display area 102 in the current two-dimensional coordinate system is obtained, and the boundary 1000 of the first display area 100 and the second display area 102 is determined.

In some cases, the first display area 100 and the second display area 102 may have a deviation between the position information at the design stage and the position information after the end of the manufacturing process due to errors at the manufacturing process stage. The specific implementation process of step S101 may be: placing a display interface in a preset two-dimensional coordinate system; then, based on the actual position information of the first display area 100 and the second display area 102 in the display panel 10 after the process is finished, coordinate information of the first display area 100 and the second display area 102 in the current two-dimensional coordinate system is respectively obtained, and the boundary 1000 of the first display area 100 and the second display area 102 is determined; the process of obtaining the actual position information of the first display area 100 and the second display area 102 after the process is finished may be: light transmittance at each position of the display panel is obtained, and a region where the light transmittance is greater than a threshold is defined as a first display region 100, and a region where the light transmittance is less than or equal to the threshold is defined as a second display region 102. Alternatively, a pseudo edge (e.g., a circle) may be drawn on the display interface according to the shape of the edge of the first display area 100 (e.g., a circle, etc.) and the position information of the first display area 100; obtaining each pixel point intersected with the simulated edge; determining whether each intersected pixel point belongs to the first display area 100 or the second display area 102, and adaptively adjusting the pseudo-edge to obtain a boundary, for example, the pixel point intersected with the pseudo-edge is divided into two areas by the pseudo-edge, which are a first area and a second area respectively, and the first area is close to the first display area 100 relative to the second area; when the area of the first region is larger than that of the second region, the current pixel point can be attributed to the first display region 100; otherwise, the current pixel point may be attributed to the second display region 102. It can be known that the finally obtained boundary is zigzag-shaped and extends along the edge of the pixel point without crossing the inside of the pixel point.

In another embodiment, before the step S101, the method may further include: when the display panel 10 displays a preset grayscale image, performing brightness compensation on the first display area 100 and/or the second display area 102 to make the brightness difference between the first display area 100 and the second display area 102 smaller; after the brightness compensation, the first display area 100 has a first gray scale, and the second display area 102 has a second gray scale. Optionally, the brightness compensation process may be: A. when the preset gray-scale image is displayed on the display interface, the first average brightness of the first display area 100 and the second average brightness of the second display area 102 are obtained. B. Adjusting the gray scale of the first display area 100 and/or the second display area 102 to make the difference between the first average brightness of the first display area 100 and the second average brightness of the second display area 102 smaller; for example, the gray scale of the first display area 100 may be adjusted based on the second average brightness of the second display area 102; specifically, a luminance gray scale curve composed of a plurality of gray scales and corresponding luminances of the first display area 100 may be obtained in advance; the gray scale corresponding to the brightness closest to the second average brightness is obtained from the brightness gray scale curve of the first display area 100 based on the second average brightness, and is used as the first gray scale of the adjusted first display area 100. In summary, after the brightness compensation, the first display region 100 has the first gray scale, and the second display region 102 has the second gray scale.

S102: the transition region 104 is determined based on the boundary 1000.

Specifically, the transition region 104 may include a portion of the first display area 100 and/or a portion of the second display area 102 in addition to the boundary 1000.

Optionally, referring to fig. 1 again, the specific implementation process of the step S102 may be: enlarging the boundary 1000 centering on the center point O of the first display area 100 to obtain an outer edge 1040, and reducing the boundary 1000 centering on the center point O to obtain an inner edge 1042; wherein the inner edge 1042 and the outer edge 1040 define a transition region 104 therebetween. I.e. when the transition area 104 comprises the boundary 1000, part of the first display area 100 and part of the second display area 102. The above-described manner of determining the transition region 104 is simple and easy to implement.

Alternatively, in some cases, the boundary 1000 between the first display area 100 and the second display area 102 may be an irregular graph, and the step S102 specifically includes: fitting the boundaries 1000 of the first display area 100 and the second display area 102, for example, to a circle (as shown in fig. 1) or a rectangle, etc.; the transition region 104 is then determined based on the fitted boundary 1000. The design mode can reduce the processing difficulty of the subsequent steps.

Alternatively, the boundary 1000 is located at an intermediate position of the transition region 104. This design may better reduce the probability of a visible demarcation of the subsequent second display area 102 and the first display area 100.

In one application scenario, as shown in fig. 1, the boundary 1000, the inner edge 1042 of the transition region 104, and the outer edge 1040 of the transition region 104 are all jagged, which may correspond to a fitted circle; and the radius of the fitting circle corresponding to the boundary 1000 is R, the radius of the fitting circle corresponding to the inner edge 1042 is R/2, the radius of the fitting circle corresponding to the outer edge 1040 is 3/2R, and at this time, the ring width of the transition region 104 is R. The transition region 104 is simple in design and has low processing difficulty.

Of course, in other application scenarios, the boundary 1000 and the transition region 104 may be designed in other manners. For example, as shown in fig. 3, fig. 3 is a schematic structural diagram of another embodiment of the boundary and the transition region in fig. 1. The boundary 1000, the inner edge 1042 of the transition region 104, and the outer edge 1040 of the transition region 104 may each correspond to a fitted rectangle; and the height of the fitted rectangle corresponding to the boundary 1000 is D, the height of the fitted rectangle corresponding to the inner edge 1042 is 0.5D, the height of the fitted rectangle corresponding to the outer edge 1040 is 1.5D, and at this time, the loop width of the transition region 104 is 0.5D. The transition region 104 is likewise designed in such a way that it has the advantages described above.

S103: the gray levels of at least some of the pixels in the transition region 104 are adjusted such that the gray level value of the transition region 104 gradually changes from the first gray level to the second gray level in the first direction from the first display region 100 to the second display region 102.

Specifically, referring to fig. 4, fig. 4 is a flowchart illustrating an embodiment corresponding to step S103 in fig. 2, where the specific implementation process of step S103 may be:

s201: respectively assigning mark values to at least part of pixel points in the transition region 104; the mark values include a first mark value and a second mark value, and the density of the pixel points having the second mark value is increased in a first direction in which the first display area 100 points to the second display area 102.

Specifically, the first flag value may be 0, and the second flag value may be 1; or the first flag value is 1 and the second flag value is 0; as long as the first flag value and the second flag value are different.

In one embodiment, please refer to fig. 5, fig. 5 is a flowchart illustrating an embodiment corresponding to step S201 in fig. 4, where the step S201 specifically includes:

s301: dividing the transition region 104 into a plurality of transition sub-regions 1044 in a circumferential direction (i.e., a direction labeled X in fig. 6) of a first display zone (not illustrated in fig. 6); in a first direction in which the first display area points to the second display area, at least a portion of the transition sub-area 1044 defines a plurality of dividing lines 1046 arranged at intervals.

Specifically, referring to fig. 6, fig. 6 is a schematic structural diagram of an embodiment corresponding to step S301 in fig. 5. The transition region 104 is schematically divided into eight transition sub-regions 1044 in fig. 6. It will be appreciated that in other embodiments, the transition region 104 may be divided into other numbers of transition sub-regions 1044. And optionally, each of the divided transition sub-regions 1044 is identical in shape. The design mode can reduce the implementation difficulty of the step S301 and can reduce the calculation difficulty of the subsequent assignment process.

Furthermore, it can be seen that, in the first direction in which the first display area (not illustrated in fig. 6) points to the second display area, at least a portion of the transition sub-area 1044 is defined with a plurality of borderlines 1046, and the intervals between adjacent borderlines 1046 located in the same transition sub-area 1044 may be the same, so as to reduce the difficulty in implementing step S201.

Alternatively, the dividing line 1046 may be defined within only one transition sub-region 1044; of course, in other embodiments, a dividing line 1046 may be defined in each transition sub-region 1044, and the dividing lines 1046 on adjacent transition sub-regions 1044 are arranged in the same manner, and the adjacent dividing lines 1046 on adjacent transition sub-regions 1044 are connected to each other to form a ring shape.

S302: marking values are respectively given to the pixel points on each boundary line 1046 in at least part of the transition sub-region 1044; the pixels located on the same boundary 1046 have a first labeled value or a second labeled value, and the ratio of the number of pixels having the second labeled value on the same boundary 1046 to the number of all pixels on the boundary 1046 where the same boundary is a first ratio, and the first ratio is increased in the first direction.

Specifically, in one embodiment, the implementation manner of step S302 may be:

A. the insertion ratio K corresponding to the current boundary 1046 is set.

Alternatively, as shown in fig. 6, a single pixel point has a first length pl, and the transition region 104 includes an inner edge 1042 closest to the center point O; the spacing between any one of the dividing lines 1046 and the inner edge 1042 is an integer multiple N of the first length pl. On this basis, the implementation process of the step a may be: a) Determining a pixel interval Gnum corresponding to the ring width based on a ratio of the ring width of the transition region 104 to the first length pl; for example, assuming that the ring width is R in fig. 6, it is expressed by the formula: gnum = R/pl. b) The ratio of the integer multiple N corresponding to the current boundary 1046 to the pixel interval Gnum is taken as an insertion ratio K; expressed as: k = N/Gnum. This way of setting the insertion ratio K is simple.

Preferably, the interval between adjacent dividing lines 1046 in the same transition sub-region 1044 is a first length pl, and the difference between the insertion ratios K corresponding to the adjacent dividing lines 1046 is the inverse of the first number 1/Gnum. For example, as shown in FIG. 6, suppose the inner edge 1042 corresponds to a circular arc radius of 0.5R, and the outer edge 1040 corresponds to a circular arc radius of 0.5R + Gnum + pl, i.e., 1.5R; then, in the direction far away from the central point O, the arc radiuses corresponding to the plurality of boundary lines 1046 are 0.5r + pl, 0.5r +2 + pl, 0.5r +3 + pl 8230, 0.5R + (Gnum-1) · pl, respectively; the insertion ratios K corresponding to the respective plurality of demarcations 1046 can be 1/Gnum,2/Gnum,3/Gnum,4/Gnum, \8230; (Gnum-1)/Gnum, respectively. By the design mode, all pixel points in the whole transition sub-region 1044 can be assigned, so that the fusion effect of the first display region and the second display region is better.

As shown in fig. 1, it is assumed that the size of the display panel is H × W and the resolution of the display panel is H × W. In the height direction L1 of the display panel 10, a first length pl = H/H of a single pixel point; in the width direction L2 of the display panel 10, the single pixel point has a first length p1= W/W.

As shown in fig. 6, when the transition region 104 is a circular ring, the first length employed in calculating the insertion ratio K may be a first length in the height direction L1 or the width direction L2.

As shown in fig. 7, fig. 7 is a schematic structural diagram of another embodiment corresponding to step S301 in fig. 5. When the transition region 104 is a rectangular ring and the transition sub-region 1044 is a rectangle, the first length used in calculating the insertion ratio K may be determined according to the spacing direction of the boundary lines 1046 in the transition sub-region 1044. For example, when the boundary lines 1046 are provided at intervals in the height direction L1, the first length corresponding to the insertion ratio K is calculated as the first length in the height direction L1; when the boundary lines 1046 are provided at intervals in the width direction L2, the first length corresponding to the insertion ratio K is calculated as the first length in the width direction L2.

B. The total number num of pixel points passed by the current boundary 1046 is obtained, and the insertion interval is determined based on the first product of the total number num and the insertion ratio K.

Specifically, when the first product is an integer, the first product is the insertion interval; when the first product is a non-integer, the rounded value of the first product may be used as the insertion interval.

In an application scenario, please continue to refer to fig. 6, assuming that a small square in fig. 6 represents a pixel point, the total number num of the pixel points passing through the current dividing line 1046 and the transition sub-region 1044 in which the dividing line is located can be obtained; for example, if the total number is 18, and the insertion ratio K corresponding to the boundary line 1046 set in the above step a is 0.3, the first product obtained by calculation is 5.4, and the corresponding insertion interval is 5.

C. Marking values are respectively given to all pixel points on the current boundary 1046 based on the insertion interval; among them, one of the multiple pixels of the number of consecutive insertion intervals on the current boundary 1046 is assigned as the first flag value, and the rest are assigned as the second flag values.

Specifically, in an application scenario, when the total number of pixel points through which the current boundary passes is 18, the insertion ratio K is 0.3, and the insertion interval is 5, one of the continuous 5 pixel points is assigned as the first flag value, and 4 of the continuous 5 pixel points are assigned as the second flag value. For another example, when the number of pixels passed by the current boundary is 18, the insertion ratio is 0.4, and the insertion interval is 7, one of the 7 continuous pixels is assigned as the first flag value, and 6 are assigned as the second flag value.

Optionally, the number of pixels with the first flag value spaced between two adjacent pixels with the second flag value on the same boundary 1046 is the same, and a pixel with the first flag value and at least one surrounding pixel with the second flag value form a repeating unit. That is, the adjacent pixel points 1046 on the same boundary line with the insertion interval number form a repeating unit, a plurality of pixel points in each repeating unit are non-overlapped, and the assignment rules of the plurality of pixel points in each repeating unit are the same. For example, when the insertion interval is 5, the assignment rules of the plurality of pixel points in all the repeating units are 0,1. The design mode can reduce the difficulty in assignment and reduce the processing capacity of the processor. It should be noted that, in some cases, when it is found that the ratio of the total number of all the pixels on the current boundary 1046 to the insertion interval is a non-integer during assignment, that is, when remaining pixels on the current boundary 1046 cannot form a repeat unit, the remaining pixels may be directly assigned as the first flag value or the second flag value or may not be flagged.

Alternatively, when the step C is implemented, marking values may be respectively assigned to all the pixels on the current boundary 1046 based on the insertion interval in the preset direction; the preset direction includes a clockwise direction or a counterclockwise direction, and the assignment process of all the borderlines 1046 in the same transition sub-area 1044 is based on the same preset direction. The design mode can further reduce the difficulty in assignment and reduce the processing capacity of the processor.

In order to assign the pixels in each transition sub-region 1044, after the transition sub-regions 1044 are obtained by dividing in step S301, each transition sub-region 1044 may define a corresponding boundary, and at this time, the step S302 may be performed for each transition sub-region 1044. Of course, in other embodiments, other convenient ways may be adopted to achieve the above-mentioned objectives.

For example, as shown in fig. 6, each of the transition sub-regions 1044 divided when the step S301 is performed has the same shape, and one of the transition sub-regions 1044 is defined with a plurality of dividing lines arranged at intervals. In this case, the specific implementation process of the step S302 may be: a1, respectively assigning a marking value to a pixel point on each boundary line 1046 in one transition sub-region 1044; the pixels located on the same boundary 1046 have a first marking value or a second marking value, and the ratio of the number of pixels having the second marking value on the same boundary 1046 to the total number of all pixels on the boundary 1046 where the same boundary is the first ratio, and the first ratio is increased in the first direction; specifically, the implementation process of step A1 may refer to step a to step C, which are not described herein again. B1, setting the assigned marking values of the pixels in the other transition subregions 1044 based on the assigned marking value of the pixel in one transition subregion 1044; when one of the transition sub-regions 1044 rotates to coincide with the other transition sub-regions 1044, the marking values assigned to the pixel points at the corresponding positions on the two transition sub-regions 1044 are the same. The method for giving the mark value is simple, and the calculation amount of the processor can be greatly reduced.

In an application scenario, the above process may be implemented based on a kernel function, and the kernel function may be any one of the prior art, which is not described in detail herein. The step A1 specifically includes: the center of the kernel function is made to coincide with the center of one of the transition sub-regions 1044, and the kernel function is used to assign a mark value to each pixel point on the boundary 1046 in one of the transition sub-regions 1044; the kernel function includes a mapping relationship between the position of the pixel in the one of the transition sub-regions 1044 and the assigned tag value. The step B1 specifically includes: after the centers of the kernel functions are overlapped with the centers of the rest transition sub-regions, marking values are given to the pixel points in the rest transition sub-regions based on the mapping relation contained in the kernel functions; the step of coinciding the center of the kernel function with the centers of the remaining transition sub-regions 1044 is equivalent to changing the coordinates of the pixel points in the mapping relationship represented by the kernel function to the coordinates of the pixel points in the remaining transition sub-regions 1044, and then, the assignment process can be directly performed based on the changed mapping relationship. The process of assigning values to the rest of transition sub-regions based on the kernel function is simple.

In summary, in the above steps S301 to S302, the transition area 104 is subdivided into a plurality of transition sub-areas 1044, and then corresponding mark values are respectively set for at least some pixel points in each transition sub-area 1044, which can improve the effect of subsequently removing the macroscopic boundary between the second display area 102 and the first display area 100. Of course, in other embodiments, the subdivision process in step S201 may not be performed, for example, the implementation process of step S201 may be: defining a plurality of annular dividing lines arranged at intervals in the transition region 104 in a first direction in which the first display area 100 points to the second display area; respectively endowing a marking value to the pixel point on each annular boundary; the pixel points on the same annular boundary have a first mark value or a second mark value, the ratio of the number of the pixel points with the second mark value on the same annular boundary to the number of all the pixel points on the annular boundary is a first ratio, and the first ratio is increased in the first direction.

S202: the gray scale of the pixel point with the first mark value is made to be the first gray scale, and the gray scale of the pixel point with the second mark value is made to be the second gray scale.

Specifically, after step S202, in the first direction in which the first display area 100 points to the second display area, the density of the pixel points having the second gray scale in the transition area 104 is increased. At this time, the brightness in the transition region 104 may gradually change from the brightness of the first display region 100 to the same as the brightness of the second display region 102 in the first direction, so that the probability of the boundary visible to the human eye between the second display region 102 and the first display region 100 may be reduced to improve the display effect.

In addition, the steps S101 to S103 define a debugging process of the display panel before normal use, and in order to facilitate direct call of the subsequent display panel in the display stage, the steps S103 further include: and burning the position information of each pixel point in the display panel and the corresponding final gray scale aiming at each preset gray scale. When the subsequent display panel is normally displayed after leaving the factory, the image to be displayed in the display panel can be obtained, the target gray scale of each pixel point in the image to be displayed is obtained, and the corresponding final gray scale is directly obtained from the burning data and displayed based on the target gray scale and the position information.

The normal display process of the display panel 10 after shipment will be described. Referring to fig. 1 and 8 together, fig. 8 is a schematic flow chart of an embodiment of an image display method according to the present application, the image display method including:

s401: acquiring a preset gray scale image to be displayed; the display interface comprises a first display area 100 and a second display area 102 which are arranged adjacently, the light transmittance of the first display area 100 is greater than that of the second display area 102, and a boundary 1000 is defined between the first display area 100 and the second display area 102.

S402: and calling gray scale data corresponding to the preset gray scale image.

Specifically, the gray scale data corresponding to the preset gray scale may be obtained from the burned data according to the preset gray scale, where the gray scale data includes gray scales corresponding to each pixel point in the first display area 100 and the second display area 102.

S403: displaying a preset gray-scale image based on the gray-scale data; the display interface is defined with a transition area 104, and the transition area 104 at least comprises a boundary 1000; the first display area 100 outside the transition area 104 has a first gray scale, and the second display area 102 outside the transition area 104 has a second gray scale; in a first direction in which the first display area 100 points to the second display area 102, the gray scale value of the transition region 104 gradually changes from the first gray scale to the second gray scale.

At this time, the brightness in the transition region 104 may gradually change from the brightness of the first display region 100 to the same brightness as the second display region 102 in the first direction, so as to achieve the purpose of reducing the probability of the occurrence of the boundary visible to human eyes between the first display region 100 and the second display region 102, so as to improve the display effect.

In one embodiment, the pixels in the transition region 104 have a first gray scale or a second gray scale, and the density of the pixels in the transition region 104 having the second gray scale is gradually increased in the first direction. The design method can reduce the difficulty of setting gray scales for the pixel points in the transition region 104 in the debugging process, and can ensure that the brightness in the transition region 104 can be gradually changed from the brightness of the first display region 100 to the brightness same as the brightness of the second display region 102 in the first direction, thereby achieving the purpose of reducing the probability of the occurrence of the visible boundary of human eyes in the first display region 100 and the second display region 102.

Alternatively, as shown in fig. 1, the transition region 104 is annular, and a portion of the transition region 104 is located in the first display area 100 and a portion of the transition region 104 is located in the second display area 102. The transition region 104 is simple to set and easy to implement.

Further, a center (e.g., point O in fig. 1) of the transition region 104 coincides with a center (e.g., point O in fig. 1) of the first display area 100, the boundary 1000 has a first distance from an inner edge 1042 of the transition region 104, the boundary 1000 has a second distance from an outer edge 1040 of the transition region 104, and the first distance and the second distance are equal; that is, the boundary 1000 is located at the middle of the transition region 104, and this design may reduce the difficulty of setting the transition region 104. When the boundary 1000, the inner edge 1042 and the outer edge 1040 are jagged, the first distance may be a distance between a circle (or a rectangle) corresponding to the boundary 1000 and a circle (or a rectangle) corresponding to the inner edge 1042, and the second distance may be a distance between a circle (or a rectangle) corresponding to the boundary 1000 and a circle (or a rectangle) corresponding to the outer edge 1040.

In one application scenario, as shown in FIG. 1, the transition region 104 is a circular ring, the radius of the inner edge 1042 (i.e., the radius of the fitted circle corresponding to the inner edge 1042) is 1/2 of the radius of the first display region 100, and the radius of the outer edge 1040 (i.e., the radius of the fitted circle corresponding to the outer edge 1040) is 3/2 of the radius of the first display region 100. For example, the radius of the first display area 100 is R, the radius of the inner edge 1042 is 0.5R, and the radius of the outer edge 1040 is 1.5R.

In one embodiment, referring to fig. 6, in the circumferential direction of the first display area 100, the transition area 104 is divided into a plurality of transition sub-areas 1044; in a first direction in which the first display area 100 points to the second display area 102, a plurality of dividing lines 1046 are defined in each transition sub-area 1044 at intervals, a ratio of the number of pixels having the second gray scale among pixels located on the same dividing line 1046 to the total number of pixels on the dividing line 1046 where the pixel has the second gray scale is a first ratio, and the first ratio increases in the first direction. That is, in the first direction in which the first display region 100 points to the second display region 102, the density of the pixel points having the second gray scale in each transition sub region 1044 is gradually increased to reduce the probability of the occurrence of the macroscopic dividing line.

Optionally, the number of the pixels having the first gray scale spaced between two adjacent pixels having the second gray scale on the same dividing line 1046 is the same, and one pixel having the first gray scale and at least one surrounding pixel having the second gray scale form a repeating unit. The design mode can reduce the difficulty of setting the gray scale of each pixel point in the early debugging process. It can be known that the ratio of the number of the pixels having the second gray scale in the repeating unit to the total number of the pixels in the repeating unit is a second ratio, and the second ratio increases in the first direction in which the first display area 100 points to the second display area 102.

Further, as shown in fig. 6, a single pixel in the display panel has a first length pl, and the specific process of obtaining the first length pl can be referred to in the foregoing embodiments, and is not described herein again. The transition region 104 has a pixel spacing Gnum that is the ratio of the ring width to the first length pl of the transition region 104; the transition region 104 includes inner edges 1040 closest to the center point of the first display area 100, the interval between any boundary 1046 and the inner edges 1040 is an integer multiple N of the first length pl, the insertion ratio K corresponding to the boundary 1046 is a ratio of the integer multiple N corresponding to the boundary 1046 to the pixel interval Gnum, and the integer value of the product of the insertion ratio K and the total number of pixel points on the boundary 1046 is the number of all pixel points included in the repeating unit. The design mode can reduce the difficulty of setting the gray scale value of the pixel point in the debugging process.

Optionally, the interval between the adjacent borderlines 1046 in the same transition sub-region 1044 is a first length pl, and the difference between the insertion ratios K corresponding to the adjacent borderlines 1046 in the same transition sub-region 1044 is the inverse 1/Gnum of the pixel interval. The design mode can enable the second display area and the first display area to have better fusion effect.

Optionally, each transition sub-region 1044 has the same shape, and when one transition sub-region 1044 rotates to coincide with another transition sub-region 1044, the gray level values of the pixel points at the corresponding positions on the two transition sub-regions 1044 are the same. The design mode can simplify the early debugging process. For example, the transition region 104 is a circular ring, the transition sub-regions 1044 are sectors, and when one sector of the transition sub-region 1044 rotates counterclockwise or clockwise to coincide with the next sector of the transition sub-region 1044, the gray level values of the pixel points at the corresponding positions of the two transition sub-regions 1044 are the same.
