As background art, as the market matures and the industry advances, the OLED display panel is gradually changed from a conventional rectangular panel to a special-shaped display panel. But the shape of the sub-pixel that most OLED display panel adopted at present is mostly the rectangle, and the pixel that the rectangle sub-pixel constitutes arranges the structure corner straight, therefore receives the shape restriction that the pixel was arranged when the rectangle sub-pixel is forming special-shaped image easily, leads to special-shaped image edge to produce the sawtooth and feels, seriously influences display effect. Therefore, the embodiment of the invention provides a pixel arrangement structure, which can ensure the display effect, and simultaneously, the adjacent sub-pixels can be shared, so that the display resolution is further effectively improved.
Example one
Referring to fig. 1, a pixel arrangement structure 01 according to an embodiment of the present invention includes a plurality of first repeating units 10 and a plurality of second repeating units 20 alternately arranged in a row direction X and a column direction Y, where each of the first repeating units 10 and the second repeating units 20 includes a first sub-pixel 011, a second sub-pixel 012, a third sub-pixel 013, and a fourth sub-pixel 014. As an example, fig. 1 only cuts out a partial region of the pixel arrangement structure 01 provided in the embodiment of the present invention; in the actual pixel arrangement structure 01, the number of the first repeating units 10 may be M, M is a positive integer not less than 1, the number of the second repeating units 20 may be the same as or equal to the number of the first repeating units 10, M is a positive integer not less than 1, or M-1, where M is a positive integer not less than 1, and the number of the first repeating units and the number of the second repeating units may be specifically determined according to the size of the display panel, which is not limited by the embodiment of the present invention.
It is understood that the row direction X refers to a length direction of the display device to which the pixel arrangement 01 is applied, and the column direction Y refers to a width direction of the display device to which the pixel arrangement 01 is applied. In the present embodiment, the first repeating unit 10 and the second repeating unit 20 may be the same repeating unit.
The first sub-pixel 011 and the second sub-pixel 012 are both in circular arc structure, and the first sub-pixel 011 and the second sub-pixel 012 have the same size; it can be understood that four first sub-pixels 011 can be spliced end to form a circular ring structure, four second sub-pixels 012 can be spliced end to form a circular ring structure, and similarly, two first sub-pixels 011 and two second sub-pixels 012 are spliced at short sides to form a circular ring structure, and so on.
Two first sub-pixels 011 and two second sub-pixels 012 are disposed around the third sub-pixel 013; specifically, the adjacent first sub-pixels 011 or second sub-pixels 012 have no connection relationship, and the two first sub-pixels 011 and the two second sub-pixels 012 are distributed outside the third sub-pixel 013 in an array.
The fourth subpixel 014 is disposed on one side of any one of the first subpixels 011 or any one of the second subpixels 012, which is far away from the third subpixel 013; alternatively, a connection line between the center of the fourth subpixel 014 and the center of the third subpixel 013 covers just the center of the first subpixel 011 or the center of the second subpixel 012.
In the pixel arrangement structure 01 provided in the embodiment of the present invention, a preset region a is set in units of the first repeating unit 10 or the second repeating unit 20, and a virtual rectangle is set in the preset region a; as shown in fig. 1-2, in the predetermined area a, two first sub-pixels 011 are disposed diagonally, and/or two second sub-pixels 012 are disposed diagonally; as shown in fig. 2, one first sub-pixel 011 is disposed at the first top corner a and the second bottom corner d of the virtual rectangle, and one second sub-pixel 012 is disposed at the second top corner b and the first bottom corner c of the virtual rectangle.
Alternatively, in the preset region a, a center connecting line between the two first subpixels 011 and a center connecting line between the two second subpixels 012 intersect, and at the same time, an intersection point of the center connecting line between the two first subpixels 011 and the center connecting line between the two second subpixels 012 is just the intersection point o of two diagonal lines of the virtual rectangle. As a preferred embodiment, in the predetermined area a, a center line between the two first sub-pixels 011 and a center line between the two second sub-pixels 012 are perpendicular.
In the pixel arrangement structure 01 provided in the embodiment of the present invention, the third subpixel 013 and the fourth subpixel 014 are both centrosymmetric graphic structures. Optionally, in the preset region a, an intersection o of two diagonal lines of the virtual rectangle is just a center point of the third subpixel 013, a central connection line between the two first subpixels 011 passes through the center point of the third subpixel 013, and an extension line of the central connection line between the two first subpixels 011 can extend to the center point of the fourth subpixel 014.
Alternatively, the third subpixel 013 and the fourth subpixel 014 are both the same shape and size. In a preferred embodiment, the third subpixel 013 and the fourth subpixel 014 are circular structures with the same size. It is noted that the shape of the third subpixel 013 and the fourth subpixel 014 can be any centrosymmetric shape, such as: squares, regular polygons, crosses, and the like; the embodiment of the invention is not particularly limited, and can be flexibly adjusted according to the design requirements of the display panel in practical application.
Alternatively, the corners of the first and second sub-pixels 011 and 012 are rounded.
With reference to fig. 1, the auxiliary line α shows a boundary of the special-shaped display, and the sub-pixel region on the opposite side of the auxiliary line α is bent to form the special-shaped display region. The auxiliary line α intersects the plurality of first sub-pixels 011 and the plurality of second sub-pixels 012, and one side of the auxiliary line α in the opposite direction is an actual region for display, and since the first sub-pixels 011 and the second sub-pixels 012 are both in arc structures, the edge of the actual region for display tends to be more arc-shaped, and the step change amplitude is smaller. As a preferred embodiment, the third subpixel 013 and the fourth subpixel 014 are both in a circular structure, so that the real edge formed by the plurality of subpixels is more attached to the edge of the actual area for displaying, and meanwhile, since the edges of the plurality of subpixels are mostly in an arc shape, the step change range can be effectively reduced, so that the right-angle edge is reduced, the saw-tooth feeling is effectively relieved, the special-shaped display area can be more accurately controlled, particularly, the edge of the special-shaped display area is smooth and clear.
Referring to fig. 3, in the pixel arrangement 01 according to the embodiment of the present invention, the third sub-pixel 013 and the fourth sub-pixel 014 may also be in the shape of a four-segment circular, in other words, the third sub-pixel 013 may be divided into four right-angled fan-shaped third sub-pixels with equal radius, and similarly, the fourth sub-pixel 014 may also be divided into four right-angled fan-shaped fourth sub-pixels with equal radius. Optionally, a gap may be provided between each third sub-pixel and another third sub-pixel adjacent to its leg, and similarly, a gap may be provided between each fourth sub-pixel and another fourth sub-pixel adjacent to its leg. By further dividing the third sub-pixel 013 and the fourth sub-pixel 014 into sub-pixels, the display fineness can be effectively improved, and the influence of the failure of partial sub-pixel areas on the whole picture display can be reduced by dividing the sub-pixels. As can be seen from fig. 1, further dividing the third subpixel 013 and the fourth subpixel 014 into subpixels can further reduce the step width and the right-angle edge, and better alleviate the jaggy feeling, while ensuring the effect. As an alternative implementation manner, in the embodiment of the present invention, further optimization of the special-shaped display effect may be achieved by adjusting the position of the Pixel Definition Layer (PDL), which is not further limited by the embodiment of the present invention.
With continued reference to fig. 3, in the pixel arrangement structure 01 provided in the embodiment of the present invention, mutual borrowing between multiple different sub-pixels can be achieved by orderly arranging the sub-pixels, so as to achieve sharing of the multiple different sub-pixels, and the embodiment of the present invention provides a technical solution for sharing five sub-pixels, so that when driving display, adjacent sub-pixels can conveniently share light:
the first sub-pixel sharing scheme 101 includes one fourth sub-pixel 014, two first sub-pixels 011, two second sub-pixels 012, and four third sub-pixels classified into four different third sub-pixels 013; the second sub-pixel sharing scheme 102 includes one fourth sub-pixel 014, two first sub-pixels 011, two second sub-pixels 012, and four third sub-pixels belonging to two different third sub-pixels 013;
the second sub-pixel sharing scheme 102 includes a fourth sub-pixel 014, four third sub-pixels belonging to two different third sub-pixels 013, a first sub-pixel 011, two first sub-pixels formed by cutting the two first sub-pixels 011, a second sub-pixel 012, and two second sub-pixels formed by cutting the two second sub-pixels 011, it can be understood that the two first sub-pixels formed by cutting the two first sub-pixels form a complete first sub-pixel 011, and the two second sub-pixels formed by cutting the two second sub-pixels form a complete second sub-pixel 011;
the third sub-pixel sharing scheme 103 includes one third sub-pixel 013, two first sub-pixels 011, two second sub-pixels 012, and four fourth sub-pixels belonging to four different fourth sub-pixels 014;
the fourth sub-pixel sharing scheme 104 includes a fourth sub-pixel 014, four third sub-pixels belonging to two different third sub-pixels 013, a first sub-pixel 011, two first sub-pixels formed by cutting the first sub-pixels 011 into two parts, a second sub-pixel 012, and two second sub-pixels formed by cutting the second sub-pixels 011 into two parts, it can be understood that the two first sub-pixels formed by cutting the first sub-pixels into two parts constitute a complete first sub-pixel 011, and the two second sub-pixels formed by cutting the second sub-pixels into two parts constitute a complete second sub-pixel 012;
the fifth sub-pixel sharing scheme 105 includes four third sub-pixels divided into two different third sub-pixels 013, four fourth sub-pixels divided into two different fourth sub-pixels 014, two first sub-pixels 011, and two second sub-pixels 012.
The second sub-pixel sharing scheme 102 is different from the fourth sub-pixel sharing scheme 104 in that the second sub-pixel sharing scheme 102 is arranged in a column direction and the fourth sub-pixel sharing scheme 104 is arranged in a row direction.
The common point of the five sub-pixel sharing schemes is that if the first sub-pixel is tiled into a complete first sub-pixel 011, the second sub-pixel is tiled into a complete second sub-pixel 012, the four third sub-pixels are tiled into a complete third sub-pixel 013, and the four fourth sub-pixels are tiled into a complete fourth sub-pixel 014, each sub-pixel sharing scheme has two first sub-pixels 011, two second sub-pixels 012, one third sub-pixel 013, and one fourth sub-pixel 014.
Referring to fig. 1 and fig. 3, in the present embodiment, in the first repeating unit 10 or the second repeating unit 20, the first sub-pixel 011 is a red sub-pixel, the second sub-pixel 012 is a blue sub-pixel, and the third sub-pixel 013 and the fourth sub-pixel 014 are green sub-pixels. In other words, in any of the above sub-pixel sharing schemes, there are two red sub-pixels, two blue sub-pixels and two green sub-pixels, where the two green sub-pixels may be eight green sub-pixels, that is, each green sub-pixel may be split into four green sub-pixels, and a plurality of sub-pixels of the same color are pieced together according to a predetermined rule to form a large sub-pixel; even if the first sub-pixel 01 or the second sub-pixel 02 is cut into two sub-pixels in the second sub-pixel sharing scheme 102 and the fourth sub-pixel sharing scheme 104, when the sub-pixels are used for sharing light emission, the sub-pixels in the sub-pixel sharing region defined by the sub-pixel sharing scheme and the sub-pixels in another sub-pixel sharing region adjacent to the sub-pixel sharing region in the column direction and/or the row direction can be spliced to form a complete sub-pixel shape.
By the sub-pixel sharing scheme, on the basis that the sawtooth feeling can be reduced by the arc-shaped edge, the high resolution of the display panel adopting the pixel arrangement structure can be further ensured, and the number PPI (Pixels Per Inc) of the sub-pixels of each inch of the display panel is effectively increased; when the display panel adopting the pixel arrangement structure is applied to special-shaped display, the special-shaped display edge is displayed more uniformly, and the sawtooth sense is weaker.

Meanwhile, the intersection point of the central connecting line of the second subpixel 022 at the first top corner I of the virtual rectangle and the first subpixel 021 at the second bottom corner L of the virtual rectangle and the central connecting line of the second subpixel 022 at the second top corner J of the virtual rectangle and the first subpixel 021 at the first bottom corner K of the virtual rectangle is just the intersection point q of two diagonal lines of the virtual rectangle. In a preferred embodiment, in the predetermined region C, the second sub-pixel 022 at the first top corner I of the virtual rectangle is perpendicular to a line connecting centers of the first sub-pixel 021 at the second bottom corner L of the virtual rectangle, and the second sub-pixel 022 at the second top corner J of the virtual rectangle is perpendicular to a line connecting centers of the first sub-pixel 021 at the first bottom corner K of the virtual rectangle.
In the pixel arrangement structure 02 provided by the embodiment of the present invention, the third sub-pixel 023 and the fourth sub-pixel 024 are both centrosymmetric pattern structures.

Optionally, the third sub-pixel 023 and the fourth sub-pixel 024 are both the same shape and size. In a preferred embodiment, the third sub-pixel 023 and the fourth sub-pixel 024 are circular structures with the same size. It is noted that the shape of the third sub-pixel 023 and the fourth sub-pixel 024 can be any centrosymmetric shape, such as: squares, regular polygons, crosses, and the like; the embodiment of the invention is not particularly limited, and can be flexibly adjusted according to the design requirements of the display panel in practical application.
Optionally, the corners of the first subpixel 021 and the second subpixel 022 are rounded.
With reference to fig. 4, the auxiliary line β indicates a boundary of the special-shaped display, and the sub-pixel region on the opposite side of the auxiliary line β is bent to form the special-shaped display region. The auxiliary line β intersects the plurality of first sub-pixels 021 and the plurality of second sub-pixels 022, and one side of the auxiliary line β, which is bent in the opposite direction, is an actual region for display. As a preferred embodiment, the third subpixel 023 and the fourth subpixel 024 are both circular structures, so that the real edge formed by the multiple subpixels is more attached to the edge of the actual area for displaying, and meanwhile, because the edges of the multiple subpixels are mostly arc-shaped, the step change amplitude can be effectively reduced, so that the right-angle edge is reduced, the saw tooth feeling is effectively relieved, the special-shaped display area can be more accurately controlled, particularly, the edge of the special-shaped display area is smooth and clear.
Referring to fig. 7, in the pixel arrangement structure 02 according to the embodiment of the present invention, the third sub-pixel 023 and the fourth sub-pixel 024 can be in a shape of a four-segment circle, that is, the third sub-pixel 023 can be further divided into four sub-pixels in a rectangular fan shape with equal radius, and similarly, the fourth sub-pixel 024 can be further divided into four sub-pixels in a rectangular fan shape with equal radius.

As can be seen from fig. 4, further dividing the third subpixel 023 and the fourth subpixel 024 into subpixels can further reduce the step variation amplitude and the right-angle edge on the premise of ensuring the effect, thereby better alleviating the jaggy.
With continued reference to fig. 7, in the pixel arrangement structure 02 provided in the embodiment of the present invention, mutual borrowing between multiple different sub-pixels can be achieved by sequentially arranging the sub-pixels, so as to achieve sharing of multiple different sub-pixels, and the embodiment of the present invention provides a technical solution for sharing five sub-pixels, and through such an arrangement, when driving display, adjacent sub-pixels can conveniently share light emission:
the first sub-pixel sharing scheme 201 includes one fourth sub-pixel 024, two first sub-pixels 021, two second sub-pixels 022, and four third sub-pixels belonging to four different third sub-pixels 023; the second sub-pixel sharing scheme 102 includes one fourth sub-pixel 024, two first sub-pixels 021, two second sub-pixels 022, and four third sub-pixels belonging to two different third sub-pixels 023;
the second sub-pixel sharing scheme 202 includes a fourth sub-pixel 024, four third sub-pixels belonging to two different third sub-pixels 023, a first sub-pixel 021, two first sub-pixels formed by cutting the first sub-pixel 021 into two parts, a second sub-pixel 022, and two second sub-pixels formed by cutting the second sub-pixel 011 into two parts, and it can be understood that the two first sub-pixels formed by cutting the first sub-pixels into two parts constitute a complete first sub-pixel 021, and the two second sub-pixels formed by cutting the second sub-pixels into two parts constitute a complete second sub-pixel 011;
the third sub-pixel sharing scheme 203 includes one third sub-pixel 023, two first sub-pixels 021, two second sub-pixels 022, and four fourth sub-pixels belonging to four different fourth sub-pixels 024;
the fourth sub-pixel sharing scheme 204 includes a fourth sub-pixel 024, four third sub-pixels belonging to two different third sub-pixels 023, a first sub-pixel 021, two first sub-pixels formed by cutting the first sub-pixel 021 into two parts, a second sub-pixel 022, and two second sub-pixels formed by cutting the second sub-pixel 011 into two parts, and it can be understood that the two first sub-pixels formed by cutting the first sub-pixels into two parts constitute a complete first sub-pixel 021, and the two second sub-pixels formed by cutting the second sub-pixels into two parts constitute a complete second sub-pixel 022;
the fifth sub-pixel sharing scheme 205 includes four third sub-pixels belonging to two different third sub-pixels 023, four fourth sub-pixels belonging to two different fourth sub-pixels 024, two first sub-pixels 021, and two second sub-pixels 022.
The second sub-pixel sharing scheme 202 differs from the fourth sub-pixel sharing scheme 204 in that the second sub-pixel sharing scheme 102 is arranged in the column direction and the fourth sub-pixel sharing scheme 104 is arranged in the row direction.
The five sub-pixel sharing schemes described above have a common point in that if the first sub-pixel is tiled as one complete first sub-pixel 021, the second sub-pixel is tiled as one complete second sub-pixel 022, the four third sub-pixels are tiled as one complete third sub-pixel 023, and the four fourth sub-pixels are tiled as one complete fourth sub-pixel 024, each sub-pixel sharing scheme has two first sub-pixels 021, two second sub-pixels 022, one third sub-pixel 023, and one fourth sub-pixel 024.
As another pixel arrangement, referring to fig. 4 and fig. 7, in the present embodiment, in the first repeating unit 11, the first sub-pixel 021 is a red sub-pixel, the second sub-pixel 022 is a blue sub-pixel, and the third sub-pixel 023 and the fourth sub-pixel 024 are both green sub-pixels; in the second repeating unit 12, the first subpixel 021 is a blue subpixel, the second subpixel 022 is a red subpixel, and the third subpixel 023 and the fourth subpixel 024 are both green subpixels. In other words, in any of the above sub-pixel sharing schemes, there are two red sub-pixels, two blue sub-pixels and two green sub-pixels, where the two green sub-pixels may be eight green sub-pixels, that is, each green sub-pixel may be split into four green sub-pixels, and a plurality of sub-pixels of the same color are pieced together according to a predetermined rule to form a large sub-pixel; even if the first sub-pixel 01 or the second sub-pixel 02 is cut into two sub-pixels in the second sub-pixel sharing scheme 202 and the fourth sub-pixel sharing scheme 204, when the sub-pixels are used for sharing light emission, the sub-pixels in the sub-pixel sharing region defined by the sub-pixel sharing scheme and the sub-pixels in another sub-pixel sharing region adjacent to the sub-pixel sharing region in the column direction and/or the row direction can be spliced to form a complete sub-pixel shape.
As another pixel arrangement, in the first repeating unit 11, the first subpixel 021 is a green subpixel, the second subpixel 022 is a red subpixel, and the third subpixel 023 and the fourth subpixel 024 are both blue subpixels; in the second repeating unit 12, the first subpixel 021 is a red subpixel, the second subpixel 022 is a green subpixel, and the third subpixel 023 and the fourth subpixel 024 are both blue subpixels. In the process of the OLED display panel, the blue sub-pixels are usually made of a blue material made of a phosphorescent material or a fluorescent material, and the stability and the material life of the blue material are not as good as those of a red material for preparing the red sub-pixels and a green material for preparing the green sub-pixels, so that compared with the former pixel arrangement mode, the pixel arrangement mode has the advantages that each blue sub-pixel can be divided into four blue sub-pixels, in other words, each four blue sub-pixels occupy the position of one blue sub-pixel, which means that the four blue sub-pixels can realize pixel sharing, and the failure of any one blue sub-pixel does not obviously change the overall display effect of the display panel Longer, thereby effectively making up the defects of the blue light material in the aspects of stability and material life.
By the sub-pixel sharing scheme, on the basis that the sawtooth feeling can be reduced by the arc-shaped edge, the high resolution of the display panel adopting the pixel arrangement structure can be further ensured, and the number PPI (Pixels Per Inc) of the sub-pixels of each inch of the display panel is effectively increased; when the display panel adopting the pixel arrangement structure is applied to special-shaped display, the special-shaped display edge is displayed more uniformly, and the sawtooth sense is weaker. Meanwhile, in the pixel arrangement structure 02 provided in this embodiment, the stability and the light emitting lifetime of the light emitting materials used by different sub-pixels are also considered.

Referring to fig. 9, an embodiment of the present invention provides a high-precision metal mask 04, where the high-precision metal mask 04 includes two shapes of openings: an opening 411 corresponding to the first sub-pixel 021 or the second sub-pixel 022, and an opening 412 corresponding to the third sub-pixel 023 or the fourth sub-pixel 024. Since the first subpixel 021 and the second subpixel 022 have the same shape, the first subpixel 021 and the second subpixel 022 may share the opening 411; since the third subpixel 023 and the fourth subpixel 024 have the same shape, the third subpixel 023 and the fourth subpixel 024 can share the opening 412. As a preferred embodiment, the openings of the corresponding sub-pixels have the same shape and position, so that the accuracy of sub-pixel evaporation can be effectively improved in the evaporation process. It can be understood that the openings may be disposed on the same mask plate, or may be disposed on different mask plates.
In summary, the high-precision metal mask provided by the embodiment of the present invention has a plurality of opening patterns, and the shape and position of the opening pattern correspond to the shape and position of the first sub-pixel, the second sub-pixel, the third sub-pixel, or the fourth sub-pixel: wherein the third sub-pixel and the fourth sub-pixel share the opening pattern; in some embodiments, the first sub-pixel and the second sub-pixel share the opening pattern.
