Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few 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. Furthermore, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the present application, are given by way of illustration and explanation only, and are not intended to limit the present application. In this application, where the context requires otherwise, the words "upper" and "lower" used in relation to the device in use or operation will generally refer to the upper and lower extremities of the device, particularly as oriented in the drawing figures; while "inner" and "outer" are with respect to the outline of the device.

In the prior art, a pixel arrangement structure of a display panel usually adopts a strip arrangement mode or a deformed strip arrangement mode, and each column of sub-pixels in the structure are made of same-color materials or alternatively made of same-color materials. Referring to fig. 1 and 2, fig. 1 is a pixel arrangement structure of a stripe arrangement, and fig. 2 is a pixel arrangement structure of a modified stripe arrangement. When a pixel structure is formed by using a high-precision metal mask, the size of a sub-pixel of a display panel is small, the size of a pixel opening in the high-precision metal mask is small, and a cross-bridge (PDL gap) between adjacent pixels is narrow along the arrangement direction of the pixels. When the resolution of the display panel needs to be improved, the size of a pixel opening and the width of a bridge collapse (PDL gap) need to be further reduced, so that the manufacturing difficulty of the high-precision metal mask is increased; with the improvement of the resolution, the PDL gap between the sub-pixels with different colors is reduced, the risk of product color mixing is high, and the taste and yield of the product are seriously influenced.

Therefore, how to improve the resolution of the display panel without increasing the manufacturing difficulty of the metal mask plate is one of the technical problems that needs to be solved urgently by those skilled in the art. The present application proposes the following solutions based on the above technical problems.

Referring to fig. 3 to 7, fig. 4 is a schematic view of a first pixel structure of a display panel of the present application, and fig. 3 is a schematic cross-sectional view taken along an AA cross-section of the display panel in fig. 4. Fig. 5 is an enlarged view of the first repeating unit 10 and the second repeating unit 20 in the pixel structure of fig. 4, fig. 6 is an enlarged view of the first repeating unit 10 and the second repeating unit 20 in the second pixel structure of the display panel of the present application, and fig. 7 is an enlarged view of the first repeating unit 10 and the second repeating unit 20 in the third pixel structure of the display panel of the present application.

In the embodiments of the present application, the second pixel structure of the display panel and the third pixel structure of the display panel are different only in the shape of the sub-pixels, and the rest are the same, and please refer to the description of the embodiments in the first pixel structure for the content that is not described in detail in the second pixel structure and the third pixel structure.

Referring to fig. 3 to 7, the present application provides a display panel including a plurality of first repeating units 10 and a plurality of second repeating units 20, the plurality of first repeating units 10 and the plurality of second repeating units 20 being alternately arranged along a first direction X and a second direction Y, the first direction X being perpendicular to the second direction Y; wherein the first repeating unit 10 includes one first sub-pixel 11, one second sub-pixel 12, and two third sub-pixels 13 arranged along the second direction Y, the two third sub-pixels 13 are disposed within a virtual rectangle 30 and are disposed near the vertices of the virtual rectangle 30 that are diagonal, the first sub-pixel 11 and the second sub-pixel 12 are disposed between the two third sub-pixels 13, and the emission colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixels 13 are different from each other; the first repeating unit 10 and the second repeating unit 20 are symmetrically disposed with a first central line 31 between the first repeating unit 10 and the second repeating unit 20 as an axis, and the first central line 31 is parallel to the second direction Y.

Referring to fig. 4 and 5, the dashed boxes disposed at the periphery of the two first sub-pixels 11 in the figures indicate the openings of the mask, and generally, the size of the openings of the mask is larger than the size of the corresponding pixels. Similarly, the dashed boxes located at the peripheries of the two second sub-pixels 12 indicate openings of another mask, and the dashed boxes located at the peripheries of the two third sub-pixels 13 indicate openings of another mask. It should be noted that one mask plate can implement the fabrication of the light emitting layers of all the sub-pixels of the same color of the display panel, and therefore, for the display panel having the pixels of three colors, three mask plates are usually required to fabricate the light emitting layers of three colors, respectively. In this embodiment, the description is mainly given of the fabrication of the first sub-pixel 11, and the fabrication method of the second sub-pixel 12 and the third sub-pixel 13 can refer to the embodiment of the first sub-pixel 11.

According to the present invention, the first repeating unit 10 and the second repeating unit 20 are axially symmetrically arranged with respect to the first central line 31 therebetween, so that the adjacent first sub-pixel 11, second sub-pixel 12 or third sub-pixel 13 can be processed by using the same mask opening, thereby increasing the size of the mask opening and further reducing the difficulty of the mask manufacturing process.

In the present embodiment, the display panel includes an OLED panel, a Mini-LED panel, a Micro-LED panel, and the like.

The pixel defining layer 60 is provided with sub-pixels of various colors, for example, the pixel defining layer 60 includes red, green, and blue sub-pixels.

I.e. in the row direction or in the column direction, two adjacent repeating units are different, one being the first repeating unit 10 and the other being the second repeating unit 20.

In the present embodiment, the first direction X may be a horizontal direction, while the second direction Y may be a vertical direction; the first direction X and the second direction Y may be interchanged. It should be noted that the first direction X may also be a direction at any angle to the horizontal direction, for example, the first direction X may be a direction at an angle of 60 degrees to the horizontal direction, and the second direction Y may be a direction at an angle of 150 degrees to the horizontal direction. In any angle, the first direction X is perpendicular to the second direction Y.

In this embodiment, the light emission colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different from each other. For example, the first sub-pixel 11 may be a red sub-pixel, the second sub-pixel 12 may be a green sub-pixel, and the third sub-pixel 13 may be a blue sub-pixel. The colors of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may be interchanged with each other, which is not limited in this application.

In the present embodiment, the first repeating unit 10 and the second repeating unit 20 are axisymmetric with respect to a first central line 31 therebetween, and the first central line 31 is disposed in parallel with the second direction Y. The short sides of the virtual rectangle 30 are parallel to the first direction X, and the long sides of the virtual rectangle 30 are parallel to the second direction Y.

In the present embodiment, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are located in the virtual rectangle 30, and the third sub-pixel 13 is located near the vertex of the virtual rectangle 30 that is diagonal. That is, the third subpixel 13, the first subpixel 11, the second subpixel 12, and the third subpixel 13 are arranged in this order in the second direction Y.

The technical solution of the present application will now be described with reference to specific embodiments.

In the display panel of the present application, referring to fig. 4 to 7, in the adjacent first repeating unit 10 and the second repeating unit 20, two first sub-pixels 11 are separately disposed, two second sub-pixels 12 are separately disposed, and two third sub-pixels 13 are connected.

In the present embodiment, the first sub-pixels 11 are separately disposed in the adjacent first and second repeating

units

10 and 20. Referring to fig. 4 to fig. 7, a distance between the first sub-pixel 11 in the first repeating unit 10 and the first sub-pixel 11 in the second repeating unit 20 in the first direction X is greater than 0. The present embodiment can improve the resolution of the display panel by separately disposing the first sub-pixels 11 in the adjacent first repeating unit 10 and second repeating unit 20, so that the two first sub-pixels 11 can be controlled independently.

In the present embodiment, in the adjacent first repeating unit 10 and second repeating unit 20, two second sub-pixels 12 are separately disposed. Referring to fig. 4 to 7, a distance between the second sub-pixel 12 in the first repeating unit 10 and the second sub-pixel 12 in the second repeating unit 20 in the first direction X is greater than 0. In the present embodiment, the second sub-pixels 12 in the adjacent first repeating unit 10 and the second repeating unit 20 are separately disposed, so that the two second sub-pixels 12 can be independently controlled, thereby improving the resolution of the display panel.

In the present embodiment, two third subpixels 13 are disposed in a connected manner in the adjacent first repeating unit 10 and second repeating unit 20. Referring to fig. 4 to fig. 7, a distance between the third sub-pixel 13 in the first repeating unit 10 and the third sub-pixel 13 in the second repeating unit 20 in the first direction X is equal to 0. In the embodiment, the third sub-pixels 13 in the first repeating unit 10 and the second repeating unit 20 are connected to form a minimum light emitting unit, so that the problem that the opening of the mask plate is too small due to the too small area of the third sub-pixels 13 is avoided, and the difficulty of the manufacturing process of the mask plate corresponding to the third sub-pixels 13 is reduced.

In the display panel of the present application, referring to fig. 4 to 7, at least one side of the third sub-pixel 13 is perpendicular to the first middle line 31, and the side of the third sub-pixel 13 perpendicular to the first middle line 31 faces the outer side of the virtual rectangle 30.

In the present embodiment, referring to fig. 4 to fig. 7, the outer side of the virtual rectangle 30 refers to a direction away from the center of the virtual rectangle 30 relative to other sides in the polygon located in the virtual rectangle 30. At least one side of the third sub-pixel 13 is perpendicular to the first middle line 31, i.e. one side of the third sub-pixel 13 is parallel to the short side of the virtual rectangle 30 and is close to the short side of the virtual rectangle 30.

In this embodiment, at least one side of the third sub-pixel 13 is set to be perpendicular to the first central line 31, and the side of the third sub-pixel 13 perpendicular to the first central line 31 faces the outer side of the virtual rectangle 30, so that the third sub-pixel 13 and another adjacent third sub-pixel 13 in the second direction Y can be manufactured by using the same opening of the mask plate, and thus the size of the opening of the mask plate can be increased, and the difficulty of manufacturing the mask plate can be reduced.

In the display panel of the present application, in the first repeating unit 10 and the second repeating unit 20 which are adjacent to each other, a pitch of the two first subpixels 11 is a first pitch a, a pitch of the two second subpixels 12 is a second pitch b, a pitch of the two third subpixels 13 is a third pitch c, and the first pitch a, the second pitch b, and the third pitch c are equal to each other.

In the present embodiment, referring to fig. 4 and fig. 5, the distance between the first sub-pixels 11 is the distance between two adjacent first sub-pixels 11 in the first direction X. The pitch between the second sub-pixels 12 is the pitch of two adjacent second sub-pixels 12 in the first direction X. The pitch between the third sub-pixels 13 is the pitch of two adjacent third sub-pixels 13 in the second direction Y. The first, second, and third pitches a, b, and c may be equal. By setting the first pitch a, the second pitch b, and the third pitch c to be equal, the pixel arrangement of the display panel can be made more compact, and the aperture ratio of the display panel can be increased.

In this embodiment, the first pitch a, the second pitch b, and the third pitch c may be set to be unequal. The first distance a, the second distance b and the third distance c are set to be unequal, so that the area sizes of the sub-pixels with different colors can be adjusted, and the white light synthesized by the sub-pixels with different colors can meet the requirements.

In the display panel of the present application, any one of the first pitch a, the second pitch b, and the third pitch c is smaller than the pitch of any two of the first subpixel 11, the second subpixel 12, and the third subpixel 13.

In the present embodiment, referring to fig. 4 and fig. 5, the first pitch a is smaller than the pitches of any two of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13. That is, the first pitch a is smaller than the pitch between the first sub-pixel 11 and the second sub-pixel 12, while the first pitch a is smaller than the pitch between the first sub-pixel 11 and the third sub-pixel 13, and while the first pitch a is smaller than the pitch between the second sub-pixel 12 and the third sub-pixel 13. Similarly, the second pitch b and the third pitch c are also set. It should be noted that, since the first pitch a is a pitch between two first sub-pixels 11, and the first sub-pixels 11 in the first repeating unit 10 and the first sub-pixels 11 in the second repeating unit 20 have the same color, the first pitch a refers to a pitch of sub-pixels of the same color in practice. That is, the pitch of the same color sub-pixels is smaller than the pitch of the different color sub-pixels.

In the embodiment, the pitch of the sub-pixels with the same color is set to be smaller than the pitch of the sub-pixels with different colors, so that two adjacent sub-pixels with the same color can be manufactured by adopting the same mask plate opening. The distance between the sub-pixels with different colors is set to be larger than the first distance a, the second distance b and the third distance c, so that the distance between the sub-pixels with different colors can be increased, and the problem of color mixing of the light emitting colors of the sub-pixels is avoided.

In the display panel of the present application, the areas of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different.

In this embodiment, the areas of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are different. Specifically, the area size of the sub-pixels may be adjusted according to the colors of the different sub-pixels. For example, the area of the blue sub-pixel is larger than that of the green sub-pixel, and the area of the green sub-pixel is larger than that of the red sub-pixel. When the first sub-pixel 11 is a red sub-pixel, the second sub-pixel 12 is a green sub-pixel, and the third sub-pixel 13 is a blue sub-pixel, the area of the third sub-pixel 13 is larger than that of the second sub-pixel 12, and the area of the second sub-pixel 12 is larger than that of the first sub-pixel 11. Since the sub-pixels of different colors have different luminous efficiencies, the luminance of white light synthesized by the sub-pixels of three colors can meet the requirement by setting the areas of the sub-pixels of different colors to be different.

In this embodiment, the areas of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are set to be different, so that the luminance of white light synthesized by the sub-pixels of three colors can meet the requirement.

In the display panel of the present application, the display panel further includes a pixel defining layer 60, the pixel defining layer 60 includes a plurality of first openings 502, and the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are disposed in the plurality of first openings 502 of the pixel defining layer 60; wherein a thickness dimension H2 of the pixel defining layer is greater than a thickness dimension of any one of the first, second, and third sub-pixels in a direction perpendicular to the display plane.

In the present embodiment, referring to fig. 3, the display panel includes a substrate 40, an array layer 50, and a pixel defining layer 60 disposed on the array layer 50, the pixel defining layer 60 includes a plurality of first openings 502 and a retaining wall 501 surrounding the first openings 502, and the first sub-pixels 11, the second sub-pixels 12, and the second sub-pixels are disposed in the first openings 502. In a direction perpendicular to the display plane, a thickness dimension H1 of the first sub-pixel is smaller than a thickness dimension H2 of the pixel defining layer, a thickness dimension (not shown) of the second sub-pixel is smaller than the thickness dimension H2 of the pixel defining layer, and a thickness dimension (not shown) of the third sub-pixel is smaller than the thickness dimension H2 of the pixel defining layer. The thickness dimension H1 of the first sub-pixel, the thickness dimension of the second sub-pixel, and the thickness dimension of the third sub-pixel may be the same or different. With the above arrangement, the banks 501 of the pixel defining layer 60 can separate the sub-pixels of different colors, thereby preventing color mixing between the sub-pixels of different colors.

In the display panel of the present application, the first sub-pixels 11 include a first light emitting material, and the first light emitting materials of two adjacent first sub-pixels 11 are connected in the first direction X.

In this embodiment, referring to fig. 3, the width dimension of the retaining wall 501 in each dashed frame in the first direction X is smaller than or equal to the width dimension of the retaining wall 501 between each two dashed frames in the first direction X.

In this embodiment, the upper surface of the retaining wall 501 away from the substrate 40 may be provided with a hydrophobic material, and the hydrophobic material is provided on the upper surface of the retaining wall 501, so that when two sub-pixels of the same color are manufactured through the same opening of the mask plate, the light emitting material of the sub-pixel is deposited on the upper surface of the retaining wall 501 to cause connection of the two sub-pixels, which affects the light emitting effect. Further, a hydrophobic material may be disposed in a region where the sidewall of the retaining wall 501 is connected to the upper surface, so as to prevent the light emitting material from depositing on the sidewall of the retaining wall 501, which may reduce the thickness uniformity of the light emitting layer.

In this embodiment, the included angle of the side wall of the retaining wall 501 and the bottom surface of the first opening 502 toward the first opening 502 is an obtuse angle, and the included angle is set to be an obtuse angle, so that the contact area with the evaporation material in the evaporation process can be increased, and the evaporation efficiency is improved. It should be noted that the included angle may also be set as a right angle, and the included angle is set as a right angle, so that deposition of the light-emitting material on the sidewall of the retaining wall 501 in the process of evaporating the light-emitting material can be prevented, and thus, when two sub-pixels with the same color are manufactured through the same opening of the mask plate, the light-emitting material is deposited on the sidewall of the retaining wall 501, which causes connection of the sub-pixels.

In this embodiment, referring to fig. 3, the first light-emitting materials of every two adjacent first sub-pixels 11 are connected, where the connection is that the first light-emitting materials of the two first sub-pixels 11 are connected in the process of performing vapor deposition by using a mask. It is noted that every second first sub-pixel 11 is connected, but not to another pair of first sub-pixels 11. Referring to fig. 3, for example, the figure includes three dashed boxes, where the first luminescent materials of the two first sub-pixels 11 in each dashed box are connected, and the first luminescent materials between the first sub-pixels 11 between each two dashed boxes are not connected. It should be further noted that the connection of the light-emitting materials includes two cases, one is that the light-emitting materials of the two first sub-pixels 11 are completely connected, and there is no break in the middle; the other is that the luminescent material portions of the two first sub-pixels 11 are connected, i.e. there are breaks in the first luminescent material of the two first sub-pixels. This is because in the evaporation process, the light emitting material of the pixel is deposited in the first opening 502 through the opening of the mask, and since the two adjacent first sub-pixels 11 are made by using the opening of the same mask, the light emitting material of a part of the pixels is deposited on the retaining wall 501 between the two first sub-pixels 11, so that the first light emitting materials of the two first sub-pixels 11 are connected. Instead of pixels manufactured by using the same mask plate opening, due to the shielding of the mask plate, the light emitting material of the pixels is not deposited on the upper surface of the corresponding retaining wall 501.

In this embodiment, the first luminescent materials of the two first sub-pixels 11 are connected, and the two first sub-pixels 11 can be manufactured through the same opening of the mask plate, so that the size of the opening of the mask plate is increased, and the difficulty in manufacturing the mask plate is reduced.

In the display panel of the present application, the second sub-pixel 12 includes a second light emitting material, the third sub-pixel 13 includes a third light emitting material, the second light emitting materials of two adjacent second sub-pixels 12 in the first direction X are connected and disposed, and the third light emitting materials of two adjacent third sub-pixels 13 in the second direction Y are connected and disposed.

In this embodiment, on the basis of the connection arrangement of the first luminescent materials of every two first sub-pixels 11, the second luminescent materials of every two second sub-pixels 12 may also be connected, and the third luminescent materials of every two third sub-pixels 13 may also be connected. It is noted that the second luminescent materials of every two second sub-pixels 12 are arranged consecutively in the first direction X, while the third luminescent materials of every two third sub-pixels 13 are arranged consecutively in the second direction Y.

In this embodiment, the second light emitting materials of every two second sub-pixels 12 are connected, and the third light emitting materials of every two third sub-pixels 13 are connected, so that the size of the opening of the mask plate for manufacturing the second sub-pixels 12 can be increased, and the size of the opening of the mask plate for manufacturing the third sub-pixels 13 can be increased, thereby reducing the difficulty in manufacturing the mask plate.

In the display panel of the present application, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are polygonal, and the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 include a triangle, a quadrangle, a pentagon, and a hexagon.

In the present embodiment, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are polygons. In some embodiments, at least one side of the first sub-pixel 11 is parallel to the first middle line 31. In the present embodiment, by disposing at least one side of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 in parallel to the first direction X or the second direction Y, the first sub-pixel 11 in two adjacent virtual rectangles 30, the second sub-pixel 12 in two adjacent virtual rectangles 30, and the third sub-pixel 13 in two adjacent virtual rectangles 30 can be brought close to each other, and thus the resolution of the display panel can be improved.

In the present embodiment, referring to fig. 4 to 7, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are polygonal, such as triangle, quadrangle, pentagon, hexagon, etc. The gravity centers of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are kept unchanged, and the shapes of the first sub-pixel, the second sub-pixel and the third sub-pixel can be changed according to actual requirements. When the shapes of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are changed, it is necessary to make the pitch of the sub-pixels of different colors larger than the distance between the sub-pixels of the same color.
