This application claims priority to Chinese Patent Application No. CN 202311871033.9, filed on Dec. 29, 2023, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of display technology and, in particular, to a display panel and a display device.
With the development of display technology, electronic products having a display function are widely applied in various fields, such as televisions, mobile phones, computers and personal digital assistants which are all electronic products having the display function, and have become an indispensable part of people's life and work. A display panel is a core structure for fulfilling a display function in an electronic product.
In the related art, an organic light-emitting diode (OLED) display panel has characteristics of self-luminescence, low power consumption, high brightness and fast response and thus has attracted wide attention. However, affected by the arrangement manner of sub-pixels in the OLED display panel, pixels in the display panel have undesired light emission, thereby affecting the overall display effect of the display panel.

The plurality of third sub-pixels form second virtual quadrilaterals, centers of the plurality of third sub-pixels are located at vertices of the second virtual quadrilaterals, and one of a first sub-pixel of the plurality of first sub-pixels or a second sub-pixel of the plurality of second sub-pixels is located within a second virtual quadrilateral of the second virtual quadrilaterals.
A circumscribed parallelogram of the first sub-pixel is a first virtual shape, at least one edge of the first sub-pixel does not coincide with the first virtual shape, a center of the first sub-pixel does not coincide with a center of the first virtual shape, a circumscribed parallelogram of the second sub-pixel is a second virtual shape, at least one edge of the second sub-pixel does not coincide with the second virtual shape, and a center of the second sub-pixel does not coincide with a center of the second virtual shape.

According to another aspect of the present disclosure, a display device is provided. The display device includes the preceding display panel.
It is to be understood that the content described in this section is neither intended to identify key or critical features of the embodiments of the present disclosure nor intended to limit the scope of the present disclosure.

To make technical solutions of the present disclosure be better understood by those skilled in the art, the technical solutions in embodiments of the present disclosure are described below clearly and completely in conjunction with drawings in the embodiments of the present disclosure. Apparently, the embodiments described below are part, not all, of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art on the premise that no creative work is done are within the scope of the present disclosure.
The term “first”, “second” and the like used in the embodiments of the present disclosure are used for distinguishing different components but not used for describing any order, quantity or significance. Similarly, the term “one”, “a”, “the” or the like does not mean a quantitative limit but indicates the existence of at least one. The term “including”, “comprising”, or the like means that elements or objects in front of the term cover elements or objects and their equivalents listed in the back of the term, but does not exclude other elements or objects. The term “connected”, “connected to each other”, or the like is not limited to physical or mechanical connections, but may include electrical connections, whether it is direct or indirect. “On”, “below”, “left”, “right” and the like are only used for indicating the relative positional relationship, and when the absolute position of a described object is changed, the relative positional relationship may also change accordingly. In addition, the description of the same and equal involved in the embodiments of the present disclosure does not mean that two objects are completely equal in size and the same in shape. The two objects are allowed to be roughly the same or roughly equal within a certain error range.
It is to be noted that if not in collision, the embodiments of the present disclosure may be combined with each other.
Pixel arrangements of the current OLED display panel include “RGBG” arrangement, “delta” arrangement and “diamond” arrangement. Through the “RGBG” arrangement, the text is blurred, the strokes are relatively thick, and the picture display is relatively blurred. Through the “delta” arrangement, the displayed text has a relatively noticeable font aliasing. Through the “diamond” arrangement, the displayed text is clear, the strokes are relatively thin, and the sense of aliasing is relatively slight. However, the “diamond” arrangement still has some technical problems to be solved. For example, as the display resolution increases, distances between different sub-pixels in the display panel become smaller and smaller, resulting in a leakage current in a process of displaying the different sub-pixels. That is, a display current in a certain sub-pixel flows to a sub-pixel adjacent to the certain sub-pixel, which leads to the crosstalk between the different sub-pixels and the undesired light emission of sub-pixels, thereby affecting the display effect of the display panel.
To solve the preceding technical problems, an embodiment of the present disclosure provides a display panel. The display panel includes multiple first sub-pixels, multiple second sub-pixels and multiple third sub-pixels. The multiple first sub-pixels and the multiple second sub-pixels form first virtual quadrilaterals, centers of the multiple first sub-pixels are located at first vertices of the first virtual quadrilaterals, centers of the multiple second sub-pixels are located at second vertices of the first virtual quadrilaterals, the first vertices and the second vertices are alternated and spaced apart, and the multiple third sub-pixels are located within the first virtual quadrilaterals. The multiple third sub-pixels form second virtual quadrilaterals, centers of the multiple third sub-pixels are located at vertices of the second virtual quadrilaterals respectively, and one of a first sub-pixel or a second sub-pixel is located within a second virtual quadrilateral. A circumscribed parallelogram of the first sub-pixel is a first virtual shape, and at least one edge of the first sub-pixel does not coincide with the first virtual shape. The center of the first sub-pixel does not coincide with the center of the first virtual shape. A circumscribed parallelogram of the second sub-pixel is a second virtual shape, and at least one edge of the second sub-pixel does not coincide with the second virtual shape. The center of the second sub-pixel does not coincide with the center of the second virtual shape. The at least one edge of the first sub-pixel that does not coincide with the first virtual shape includes a first edge. The at least one edge of the second sub-pixel that does not coincide with the second virtual shape includes a second edge. In at least part of adjacent first sub-pixels and second sub-pixels, an included angle between the first edge and the second edge is denoted as α1, and 0°≤α1≤45°.
With the preceding technical solutions adopted, the at least one edge of the first sub-pixel does not coincide with the circumscribed first virtual shape of the first sub-pixel, and the at least one edge of the second sub-pixel does not coincide with the circumscribed second virtual shape of the second sub-pixel so that the distance from the first sub-pixel to the second sub-pixel can be increased, display leakage current between the first sub-pixel and the second sub-pixel can be reduced, and the crosstalk between different sub-pixels and undesired light emission of sub-pixels can be improved, thereby improving the display effect of the display panel. Meanwhile, in at least part of the adjacent first sub-pixels and second sub-pixels, a relatively small included angle is provided between the first edge and the second edge so that a shape of the first sub-pixel and a shape of the second sub-pixel can be ensured to be consistent, and so that at least part of the adjacent first sub-pixels and second sub-pixels can have consistent display light emission situations, thereby facilitating the improvement in the display uniformity of the display panel.
The preceding is the core idea of the present disclosure. The technical solutions in the embodiments of the present disclosure are described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present disclosure.
The first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel may have different emitted colors. For example, the first sub-pixel 10 may be a red sub-pixel whose emitted color is red, the second sub-pixel 20 may be a blue sub-pixel whose emitted color is blue, and the third sub-pixel 30 may be a green sub-pixel whose emitted color is green. However, the emitted colors of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 are not limited to this and may be designed according to actual requirements. In other optional embodiments, the colors of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 may also be the same or may also be not the same. On the premise that the core inventive points of the embodiment of the present disclosure can be achieved, the emitted colors of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 are not specifically limited in the embodiment of the present disclosure. For ease of description, the technical solution of the embodiment of the present disclosure is described exemplarily using an example in which the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 have different emitted colors.
With continued reference to
Correspondingly, the multiple third sub-pixels 30 form the second virtual quadrilaterals B, and the centers of the multiple third sub-pixels 30 are located at the vertices of the second virtual quadrilaterals B respectively, that is, third sub-pixels 30 that are located at four vertices of a respective second virtual quadrilateral B respectively are arranged in an array of 2*2, and one of a first sub-pixel 10 or a second sub-pixel 20 is located within a second virtual quadrilateral B. In this case, the second virtual quadrilaterals B may include two types. A first sub-pixels 10 of the multiple first sub-pixels 10 is located within a first-type second virtual quadrilateral Ba of the first-type second virtual quadrilaterals Ba, and a second sub-pixels 20 of the multiple second sub-pixels 20 is located within a second-type second virtual quadrilateral Bb of the second-type second virtual quadrilaterals Bb so that light rays emitted by third sub-pixels 30 located at vertices of the first-type second virtual quadrilateral Ba can be mixed with the light rays emitted by the first sub-pixel 10, and light rays emitted by third sub-pixels 30 located at vertices of the second-type second virtual quadrilateral Bb can be mixed with the light rays emitted by the second sub-pixel 20, thereby facilitating the improvement in the display resolution of the display panel.
It is to be understood that the centers of the multiple first sub-pixels 10, the centers of the multiple second sub-pixels 20 and the centers of the multiple third sub-pixels 30 that are mentioned in the embodiment of the present disclosure may be light emission centers of the multiple first sub-pixels 10, light emission centers of the multiple second sub-pixels 20 and light emission centers of the multiple third sub-pixels 30, respectively. The shapes of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 that are shown in
The at least one edge of the first sub-pixel does not coincide with the first virtual shape, that is, one, two, or more edges of the first sub-pixel may not coincide with the first virtual shape. Similarly, the at least one edge of the second sub-pixel does not coincide with the second virtual shape, that is, one, two, or more edges of the second sub-pixel may not coincide with the second virtual shape. On the premise that the core inventive points of the present disclosure can be achieved, this is not specifically limited in the present disclosure.
Similarly,
It is to be understood that, with continued reference to
It is also to be understood that lateral leakage currents are present between sub-pixels of the display panel, and the distance between two adjacent sub-pixels is the lateral leakage current distance between the two adjacent sub-pixels. Generally, the smaller the lateral leakage current distance, the smaller a potential barrier required for carriers to overcome when the carriers are transmitted between the two adjacent sub-pixels so that the larger the number of directional carriers moving between the two adjacent sub-pixels, the larger the lateral leakage current generated. On the contrary, the larger the lateral leakage current distance between the two adjacent sub-pixels, the smaller the lateral leakage current generated.
In conjunction with
In addition,
The value range of α1 is 0°≤α1≤45° so that in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the first edge 11 and the second edge 21 can be parallel to each other or can have a relatively small included angle, that is, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the included angle α1 between the first edge 11 and the second edge 21 may be 0°, 5°, 10°, 20°, 30°, 40°, or 45°. On the premise that the core inventive points of the embodiment of the present disclosure can be achieved, this is not specifically limited in the embodiment of the present disclosure. In an optional embodiment, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, extension directions of the first edge 11 and the second edge 21 are roughly the same so that the shapes of the multiple first sub-pixels 10 and the multiple second sub-pixels 20 can remain consistent. In this way, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the value range of the included angle α1 between the first edge 11 and the second edge 12 is 0°≤α1≤45° so that the shapes of the multiple first sub-pixels 10 and the shapes of the multiple second sub-pixels 20 can be similar, and so that the adjacent first sub-pixel 10 and second sub-pixel 20 can have consistent display light emission situations, thereby facilitating the improvement in the display uniformity of the adjacent first sub-pixel 10 and second sub-pixel 20 and the display effect of the display panel 100.
In conclusion, the at least one edge of the first sub-pixel does not coincide with the circumscribed first virtual shape of the first sub-pixel, and the at least one edge of the second sub-pixel does not coincide with the circumscribed second virtual shape of the second sub-pixel so that the distances from the multiple first sub-pixels to the multiple second sub-pixels can be increased, the display leakage currents between the multiple first sub-pixels and the multiple second sub-pixels can be reduced, and the crosstalk between the different sub-pixels and the undesired light emission of the sub-pixels can be improved, thereby improving the display effect of the display panel. Meanwhile, in at least part of the adjacent first sub-pixels and second sub-pixels, a relatively small included angle is provided between the first edge and the second edge so that the shapes of the multiple first sub-pixels and the shapes of the multiple second sub-pixels can be ensured to be consistent, and so that at least part of the adjacent first sub-pixels and second sub-pixels can have consistent display light emission situations, thereby facilitating the improvement in the display uniformity of the display panel.

Similarly, with continued reference to
In addition, the first edge 11 of the first sub-pixel 10 and the second edge 21 of the second sub-pixel 20 are cutting lines of the chamfers of the first sub-pixel 10 and the second sub-pixel 20 respectively so that when a relatively small included angle is provided between the first edge of the first sub-pixel 10 and the second edge 20 of the second sub-pixel 20 for at least part of adjacent first sub-pixels and second sub-pixels, the shapes of the multiple first sub-pixels 10 and the shapes of the multiple second sub-pixels 20 can remain consistent after the multiple first sub-pixels 10 and the multiple second sub-pixels 20 are chamfered, and the multiple first sub-pixels 10 and the multiple second sub-pixels 20 can have consistent light emission situations, thereby facilitating the improvement in the display uniformity of the display panel.
In an optional embodiment, in conjunction with
It is to be noted that in the embodiment of the present disclosure, the first pointing direction and the second pointing direction in at least part of the adjacent first sub-pixels and second sub-pixels are the same. That is, as shown in
As a feasible embodiment,
In an exemplary embodiment, the two first pixel groups 110 that are adjacent and arranged along the first direction X are a first pixel group 111 and a second first pixel group 112. In this case, in the first pixel group 111, the first pointing direction X11 of the first sub-pixel 10 is the same as the first pointing direction X21 of the second sub-pixel 20, and in the second first pixel group 112, the first pointing direction X12 of the first sub-pixel 10 is the same as the first pointing direction X22 of the second sub-pixel 20 so that in the same first pixel group 110 (111 or 112), the chamfer orientations of the first sub-pixel 10 and the second sub-pixel 20 can remain consistent, and the first sub-pixel 10 and the second sub-pixel 20 can have consistent light emission situations, thereby improving the display uniformity of the first sub-pixel 10 and the second sub-pixel 20 in the same first pixel group 110 (111 or 112).
In addition, the first pointing direction X11 of the first sub-pixel 10 in the first pixel group 111 is opposite to the first pointing direction X12 of the first sub-pixel 10 in the second first pixel group 112 so that the chamfer orientations of the first sub-pixels 10 in the adjacent first pixel group 111 and second first pixel group 112 can be different, that is, compared with the situation in which the first sub-pixels 10 are not chamfered, light rays center offset directions of light rays emitted by the first sub-pixels 10 in the first pixel group 111 and the second first pixel group 112 are opposite, that is, light rays emitted by any two adjacent first sub-pixels 10 are ensured to have different light rays center offset directions in the first direction X to prevent the display light emission effect in the first direction X from being affected due to that the light rays centers of light rays emitted by first sub-pixels 10 in the first direction X offset toward the same side, thereby facilitating the uniform distribution of the light rays emitted by the first sub-pixels 10 in the first direction X, further improving the display color deviation in the first direction X and improving the display uniformity in the first direction X. Similarly, the second pointing direction X21 of the second sub-pixel 20 in the first pixel group 111 is opposite to the second pointing direction X22 of the second sub-pixel 20 in the second first pixel group 112 so that light rays center offset directions of light rays emitted by second sub-pixels 20 in the first pixel group 111 and the second first pixel group 112 can be opposite, that is, light rays emitted by any two adjacent second sub-pixels 20 are ensured to have different light rays center offset directions in the first direction X to prevent the display light emission effect in the first direction X from being affected due to that the light rays centers of light rays emitted by second sub-pixels 20 in the first direction X offset toward the same side, thereby facilitating the uniform distribution of the light emitted by the second sub-pixels 20 in the first direction X, further improving the display color deviation in the first direction X and improving the display uniformity in the first direction X.
It is to be understood that in addition to that the multiple first sub-pixels 10 and the multiple second sub-pixels 20 are alternately arranged along the first direction X, the multiple first sub-pixels 10 and the multiple second sub-pixels 20 may also be alternately arranged along the second direction Y intersecting the first direction X so that the multiple first sub-pixels 10 and the multiple second sub-pixels 20 can be arranged in an array in the first direction X and the second direction Y, and in the first direction X and the second direction Y, light rays emitted by any adjacent first sub-pixel 10 and second sub-pixel 20 can be mixed with each other, thereby preventing a single-colored color edge of a picture displayed by the display panel and ensuring the display quality of the display panel. In this case, first pointing directions of the multiple first sub-pixels 10 arranged along the second direction Y and second pointing directions of the multiple second sub-pixels 20 arranged along the second direction Y may be the same or different.
As another feasible embodiment,
In an embodiment, with continued reference to
Meanwhile, when the first pointing direction X1 is opposite to the second pointing direction X2 in the first sub-pixel 10 and the second sub-pixel 20 that are adjacent and arranged along the second direction Y, center offset directions of the first sub-pixel 10 and the second sub-pixel 20 that are adjacent and arranged along the second direction are opposite so that the first virtual quadrilateral formed by lines connecting the centers of first sub-pixels 10 and second sub-pixels 20 that are adjacent and arranged along the first direction X, and first sub-pixels 10 and second sub-pixels 20 that are adjacent and arranged along the second direction Y can be a parallelogram.
Optionally, with continued reference to
In an embodiment, when the display panel 100 displays an image, there is a color edge effect, that is, noticeable colorful strips deviating from an original image are prone to appear at the edge of the displayed image. For example, when the edge of the image includes red sub-pixels and blue sub-pixels that are arranged sequentially, after mixture, the red sub-pixels and the blue sub-pixels are prone to form a magenta color edge; and when the edge of the image includes green sub-pixels that are arranged sequentially, a green color edge is prone to form. The center of the first virtual quadrilateral A does not coincide with the center of the third sub-pixel 30 that is located within the first virtual quadrilateral A, so the positions of the first sub-pixels 10 and the positions of the second sub-pixels 20 at the vertices of the first virtual quadrilaterals A can be adjusted flexibly. When the edge of a display region includes first sub-pixels 10 and second sub-pixels 20 that are alternately arranged, the positions of the first sub-pixels 10 and/or the second sub-pixels 20 may be adjusted so that the first sub-pixels 10 and the second sub-pixels 20 at the edge of the display region cannot be on a straight line. This reduces the sensitivity of a human eye to rows (or columns) formed by the first sub-pixels 10 and the second sub-pixels 20 at the edge of the display region so that a magenta color edge effect can be weakened.
Optionally, with continued reference to
It is to be understood that in the embodiment of the present disclosure, the first direction X intersects the second direction Y so that an included angle can be provided between the first direction X and the second direction Y, and the included angle may be any angle greater than 0° and less than 180°. In this case, a row of sub-pixels may be the first direction X, and a column of sub-pixels may be the second direction Y; or a row of sub-pixels is the second direction Y, and a column of sub-pixels is the first direction X. This is not specifically limited in the embodiment of the present disclosure.
In an optional embodiment, with continued reference to
It is to be noted that
In another optional embodiment, with continued reference to
It is to be understood that the display panel may include two third directions (W and W′), the two third directions may be a first third direction W and a second third direction W′, the first third direction W intersects the second third direction W′, the first third direction W and the second third direction W′ further intersect the first direction X and the second direction Y, and included angles between the first third direction W and the first direction X (or the second direction Y) may be the same as or different from included angles between the second third direction W′ and the first direction X (or the second direction Y). This is not specifically limited in the embodiment of the present disclosure. For ease of description, unless otherwise limited, the third direction mentioned in the embodiments below refers to the first third direction W.
As a feasible embodiment, referring to
The extension direction of the third sub-pixel 30 may be an extension direction of the longest edge in the third sub-pixel 30. Extension directions of third sub-pixels 30 that are arranged along the third direction W and between two adjacent first sub-pixels 10 are enabled to be parallel to the third direction W, and extension directions of the third sub-pixels 30 that are arranged along the third direction W and between two adjacent second sub-pixels 20 are enabled to intersect the third direction so that four adjacent third sub-pixels 30, that is, four third sub-pixels 30 located at four vertices of the same second virtual quadrilateral B, for example, a first third sub-pixel 301, a second third sub-pixel 302, a third sub-pixel 303 and a fourth third sub-pixel 304, can have different orientations, facilitating the display uniformity of the four directions.
Optionally, with continued reference to
In an embodiment, the first pointing directions X1 of the two first sub-pixels 10 in the same second pixel group 120 are opposite so that the two first sub-pixels 10 that are adjacent and arranged along the third direction W can have different chamfer orientations, and light ray center offset directions of light rays emitted by the two first sub-pixels 10 can be opposite, that is, the light rays emitted by the two first sub-pixels 10 in the same second pixel group 120 can be ensured to have different light ray center offset directions in the third direction W to prevent the display light emission effect in the third direction W from being affected due to that light ray centers of light rays emitted by first sub-pixels 10 in the third direction W offset toward the same side, thereby facilitating the uniform distribution of the light rays emitted by the first sub-pixels 10 in the third direction W, further improving the display color deviation in the third direction W and improving the display uniformity in the third direction W.
Similarly, the second pointing directions X2 of the two second sub-pixels 20 in the same third pixel group 130 are opposite so that the two second sub-pixels 20 that are adjacent and arranged along the third direction W can have different chamfer orientations, and light ray center offset directions of light rays emitted by the two second sub-pixels 20 can be opposite, that is, the light rays emitted by the two second sub-pixels 20 in the same third pixel group 130 can be ensured to have different light ray center offset directions in the third direction W to prevent the display light emission effect in the third direction W from being affected due to that light ray centers of light rays emitted by second sub-pixels 20 in the third direction W offset toward the same side, thereby facilitating the uniform distribution of the light rays emitted by the second sub-pixels 20 in the third direction W, further improving the display color deviation in the third direction W and improving the display uniformity in the third direction W.
Further, with continued reference to
Correspondingly, when the two second sub-pixels 20 that are adjacent and arranged along the third direction W form the third pixel group 130, second pointing directions X2 of two second sub-pixels 20 that are adjacent and belong to different third pixel groups 130 are the same. In this way, light emission situations of second sub-pixels 20 in two adjacent third pixel groups 130 can remain consistent so that the display uniformity of the display panel 100 in the third direction W can be improved.
Optionally,
Exemplarily, when two first virtual quadrilaterals A that are adjacent and arranged along the first direction X have a common edge, centers of five first sub-pixels 10 and centers of five second sub-pixels 20 are required to be connected to form one first virtual group AZ. In this case, among two first sub-pixels 10 and two second sub-pixels 20 that are located at four vertices of the first-type virtual quadrilateral A1, center offset directions of a first sub-pixel 10 and a second sub-pixel 20 that are adjacent and arranged along the first direction X are the same, that is, orientations of chamfers are the same, while center offset directions of a first sub-pixel 10 and a second sub-pixel 20 that are adjacent and arranged along the second direction Y are opposite, that is, orientations of chamfers are opposite, so that the first-type virtual quadrilateral A1 can be a parallelogram.
Among two first sub-pixels 10 and two second sub-pixels 20 that are located at four vertices of the second-type virtual quadrilateral A2, chamfer orientations of one group of a first sub-pixel 10 and a second sub-pixel 20 that are adjacent and arranged along the first direction face to each other while chamfer orientations of the other group of a first sub-pixel 10 and a second sub-pixel 20 that are adjacent and arranged along the first direction face away from each other; center offset directions of a first sub-pixel 10 and a second sub-pixel 20 that are adjacent and arranged along the second direction Y are opposite, that is, orientations of chamfers are opposite, and the offset amount of the center of a second sub-pixel 20 located in the previous row (or column) with respect to the center of a first sub-pixel 10 located in the next row in one group of a first sub-pixel 10 and a second sub-pixel 20 that are arranged along the second direction Y is the first offset amount; and when the offset amount of the center of a first sub-pixel 10 located in the previous row (or column) with respect to the center of a second sub-pixel 20 located in the next row in the other group of a first sub-pixel 10 and a second sub-pixel 20 that are arranged along the second direction Y is the second offset amount, the first offset amount may be equal to the second offset amount so that the second-type virtual quadrilateral A2 can be an isosceles trapezoid.
The arrangement manner of two first sub-pixels 10 and two second sub-pixels 20 that are located at four vertices of the third-type virtual quadrilateral A3 is similar to the arrangement manner of the two first sub-pixels 10 and the two second sub-pixels 20 in the first-type virtual quadrilateral A1. A difference lies in that center offset directions of the first sub-pixel 10 and the second sub-pixel 20 that are adjacent and arranged along the first direction X in the third-type virtual quadrilateral A3 are opposite to center offset directions of the first sub-pixel 10 and the second sub-pixel 20 that are adjacent and arranged along the first direction X in the first-type virtual quadrilateral A1 so that the third-type virtual quadrilateral A3 can also be a parallelogram, and the third-type virtual quadrilateral A3 and the first-type virtual quadrilateral A1 can mirror each other.
The arrangement manner of two first sub-pixels 10 and two second sub-pixels 20 that are located at four vertices of the fourth-type virtual quadrilateral A4 is similar to the arrangement manner of the two first sub-pixels 10 and the two second sub-pixels 20 in the second-type virtual quadrilateral A2. A difference lies in that center offset directions of first sub-pixels 10 that are arranged along the first direction X and located within the fourth-type virtual quadrilateral A4 and the second-type virtual quadrilateral A2 respectively are opposite, and center offset directions of second sub-pixels 20 that are arranged along the first direction X and located within the fourth-type virtual quadrilateral A4 and the second-type virtual quadrilateral A2 respectively are opposite so that the fourth-type virtual quadrilateral A4 can also be an isosceles trapezoid, and the fourth-type virtual quadrilateral A4 and the second-type virtual quadrilateral A2 can mirror each other.
In this way, the first-type virtual quadrilateral A1 and the third-type virtual quadrilateral A3 form parallelograms mirroring each other, and the second-type virtual quadrilateral A2 and the fourth-type virtual quadrilateral A4 form isosceles trapezoids mirroring each other so that first pointing directions X1 of any two first sub-pixels 10 that are adjacent and arranged along the first direction X can be opposite, and second pointing directions of any two second sub-pixels 20 that are adjacent and arranged along the first direction X can be opposite, thereby facilitating the improvement in the display uniformity in the first direction X and the color deviation in the first direction X. Meanwhile, the interval of centers of a first sub-pixel 10 and a second sub-pixel 20 on a short edge of each of the second-type virtual quadrilateral A2 and the fourth-type virtual quadrilateral A4 is relatively small so that chamfer orientations of the first sub-pixel 10 and the second sub-pixel 20 can face to each other to enable relatively long distance to be provided between the first sub-pixel 10 and the second sub-pixel 20, and relatively large space can be provided between the first sub-pixel 10 and the second sub-pixel 20. Therefore, a relatively large space can also be provided for configuring other structures such as a support column while lateral leakage current between the first sub-pixel 10 and the second sub-pixel 20 can be reduced so that an additional space is not required for configuring other structures, thereby facilitating the improvement in the resolution of the display panel.
It is to be understood that the preceding is solely described using an example in which the first pointing direction X1 and the second pointing direction X2 are parallel to the first direction X, while in the embodiment of the present disclosure, as shown in
As a feasible embodiment,
Exemplarily, using β11 being 90° and β12 being 180° as an example, the any four first sub-pixels 10 that are adjacent and arranged sequentially along the first direction X are a first sub-pixel 101, a second first sub-pixel 102, a third first sub-pixel 103 and a fourth first sub-pixel 104 respectively, and if an included angle between the first pointing direction X11 of the first sub-pixel 101 and a reference direction is 0°, the included angle β11 between the first pointing direction X12 of the second first sub-pixel 102 and the first pointing direction X11 of the first sub-pixel 101 is 90°, that is, an included angle between the first pointing direction X12 of the second first sub-pixel 102 and the reference direction is 90°; an included angle between a first pointing direction X13 of the third first sub-pixel 103 and the first pointing direction X12 of the second first sub-pixel 102 is also 90°, and the included angle β12 between the first pointing direction X13 of the third first sub-pixel 103 and the first pointing direction X11 of the first sub-pixel 101 is 180° so that an included angle between the first pointing direction X13 of the third first sub-pixel 103 and the reference direction can be 180°; and an included angle between a first pointing direction X14 of the fourth first sub-pixel 104 and the first pointing direction X13 of the third first sub-pixel 103 is 90°, and an included angle between the first pointing direction X14 of the fourth first sub-pixel 104 and the first pointing direction X12 of the second first sub-pixel 102 is 180° so that an included angle between the first pointing direction X14 of the fourth first sub-pixel 104 and the first pointing direction X11 of the first sub-pixel 101 can be 270°, that is, an included angle between the first pointing direction X14 of the fourth first sub-pixel 104 and the reference direction is 270°. In this case, among the any four first sub-pixels 10 that are adjacent and arranged sequentially along the first direction X, the first pointing direction X11 of the first sub-pixel 101 and the first pointing direction X13 of the third first sub-pixel 103 are parallel to the first direction X, and the first pointing direction X12 of the second first sub-pixel 102 and the first pointing direction X14 of the fourth first sub-pixel 104 are parallel to the second direction Y. In this way, included angles between the any four first sub-pixels 10 that are adjacent and arranged sequentially along the first direction X and the reference direction increase sequentially, and an included angle between the two adjacent first sub-pixels 10 differs by 90° so that chamfer orientations of the any four first sub-pixels 10 that are adjacent and arranged sequentially along the first direction X can be four directions on the plane respectively, further balancing the configured positions of the any four first sub-pixels 10 that are adjacent and arranged sequentially along the first direction X, facilitating the improvement in the color deviation in the four directions of the display panel 100 and improving the display uniformity of the multiple first sub-pixels 10 and the entire display panel 100.
Optionally, with continued reference to
With the preceding arrangement manner adopted, among the any four first sub-pixels 10 that are adjacent and arranged sequentially along the second direction Y, first pointing directions X1 of two first sub-pixels 10 can be parallel to the first direction X while first pointing directions X1 of the other two first sub-pixels 10 can be parallel to the second direction Y. In this case, chamfer orientations of the any four first sub-pixels 10 that are adjacent and arranged sequentially along the second direction Y may be four directions on the plane respectively so that the configured positions of the any four first sub-pixels 10 that are adjacent and arranged sequentially along the second direction Y can be balanced, thereby facilitating the improvement in the color deviation in the four directions of the display panel 100 and improving the display uniformity of the multiple first sub-pixels 10 and the entire display panel 100.
It is to be noted that
In another optional embodiment, with continued reference to
Exemplarily, using β21 being 90° and β22 being 180° as an example, the any four second sub-pixels 20 that are adjacent and arranged sequentially along the first direction X are a first second sub-pixel 201, a second second sub-pixel 202, a third second sub-pixel 203 and a fourth second sub-pixel 204 respectively, and if an included angle between the second pointing direction X21 of the first second sub-pixel 201 and a reference direction is 0°, the included angle β21 between the second pointing direction X22 of the second second sub-pixel 202 and the second pointing direction X21 of the first second sub-pixel 201 is 90°, that is, an included angle between the second pointing direction X22 of the second second sub-pixel 202 and the reference direction is 90°; an included angle between a second pointing direction X23 of the third second sub-pixel 203 and the second pointing direction X22 of the second second sub-pixel 202 is also 90°, and the included angle β22 between the second pointing direction X23 of the third second sub-pixel 203 and the second pointing direction X21 of the first second sub-pixel 201 is 180° so that an included angle between the second pointing direction X23 of the third second sub-pixel 203 and the reference direction can be 180°; and an included angle between a second pointing direction X24 of the fourth second sub-pixel 204 and the second pointing direction X23 of the third second sub-pixel 203 is 90°, and an included angle between the second pointing direction X24 of the fourth second sub-pixel 204 and the second pointing direction X22 of the second second sub-pixel 202 is 180° so that an included angle between the second pointing direction X24 of the fourth second sub-pixel 204 and the second pointing direction X21 of the first second sub-pixel 201 can be 270°, that is, an included angle between the second pointing direction X24 of the fourth second sub-pixel 204 and the reference direction is 270°. In this case, among the any four second sub-pixels 20 that are adjacent and arranged sequentially along the first direction X, the second pointing direction X21 of the first second sub-pixel 201 and the second pointing direction X23 of the third second sub-pixel 203 are parallel to the first direction X, and the second pointing direction X22 of the second second sub-pixel 202 and the second pointing direction X24 of the fourth second sub-pixel 204 are parallel to the second direction Y. In this way, included angles between the any four second sub-pixels 20 that are adjacent and arranged sequentially along the first direction X and the reference direction increase sequentially, and an included angle between the two adjacent second sub-pixels 20 differs by 90° so that chamfer orientations of the any four second sub-pixels 20 that are adjacent and arranged sequentially along the first direction X can be four directions on the plane respectively, further balancing the configured positions of the any four second sub-pixels 20 that are adjacent and arranged sequentially along the first direction X, facilitating the improvement in the color deviation in the four directions of the display panel 100 and improving the display uniformity of the multiple second sub-pixels 20 and the entire display panel 100.
Optionally, with continued reference to
With the preceding arrangement manner adopted, among the any four second sub-pixels 20 that are adjacent and arranged sequentially along the second direction Y, second pointing directions X2 of two second sub-pixels 20 can be parallel to the first direction X while second pointing directions X2 of the other two second sub-pixels 20 can be parallel to the second direction Y. In this case, chamfer orientations of the any four second sub-pixels 20 that are adjacent and arranged sequentially along the second direction Y may be four directions on the plane respectively so that the configured positions of the any four second sub-pixels 20 that are adjacent and arranged sequentially along the second direction Y can be balanced, thereby facilitating the improvement in the color deviation in the four directions of the display panel 100 and improving the display uniformity of the multiple second sub-pixels 20 and the entire display panel 100.
It is to be noted that
It is to be understood that chamfer orientations of the multiple first sub-pixels and the multiple second sub-pixels can affect the display uniformity of the display panel in various directions, and chamfer magnitudes of the multiple first sub-pixels and the multiple second sub-pixels affect the overall display brightness of the display panel.
Optionally, as shown in
It is to be understood that with respect to the first virtual shape 10′, a portion cut along the first edge 11 of the first sub-pixel 10 may be a triangle, the first edge 11 may serve as the base of the triangle, and a connection line between the first connection point o1 and the first virtual point o1′ and a connection line between the second connection point o2 and the first virtual point o1′ serve as two waists of the triangle, and if the connection line between the first connection point o1 and the first virtual point o1′ is a first connection line, and the connection line between the second connection point o2 and the first virtual point o1′ is a second connection line, the length of the first connection line may be denoted as 111, and the length of the second connection line may be denoted as 112. In this case, the length of the first connection line and the length of the second connection line can embody the size of the cut triangle, and the larger the size, the larger the offset amount of the center of the first sub-pixel 10 with respect to the center of the first virtual shape 10′, the larger the distances from the first sub-pixel 10 to other sub-pixels adjacent to the first sub-pixel 10 so that lateral leakage currents between the first sub-pixel 10 and the other sub-pixels adjacent to the first sub-pixel 10 can be smaller; but when the cut triangle has a relatively large size, the display brightness of the multiple first sub-pixels 10 is reduced so that color deviation can be caused, and the overall display brightness of the display panel can be even reduced.
In conclusion, in this embodiment, the ratio between the minimum distance 111 from the first connection point o1 to the first virtual point o1′ and the length L11 of the first virtual edge 11′ is limited to be greater than or equal to 1/40 and less than or equal to 1/2, and the ratio between the minimum distance 112 from the second connection point o2 to the first virtual point o1′ and the length L12 of the second virtual edge 12′ is limited to be greater than or equal to 1/40 and less than or equal to 1/2 so that on the premise that the multiple first sub-pixels 10 are ensured to have enough display brightness, enough small lateral leakage currents can be provided between the first sub-pixel 10 and the other sub-pixels adjacent to the first sub-pixel 10, thereby improving the overall display effect of the display panel. For example, 1/20≤111/L11≤2/5, and 1/20≤112/L12≤2/5.
In an optional embodiment, 111=112, that is, the cut triangle may be an isosceles triangle so that the multiple first sub-pixels 10 can be ensured to have uniform chamfers, thereby improving the light emission effect of the multiple first sub-pixels 10.
Optionally, as shown in
It is also to be understood that with respect to the second virtual shape 20′, a portion cut along the second edge 21 of the second sub-pixel 20 may also be a triangle, the second edge 21 may serve as the base of the triangle, and a connection line between the third connection point o3 and the second virtual point o2′ and a connection line between the fourth connection point o4 and the second virtual point o2′ serve as two waists of the triangle, and if the connection line between the third connection point o3 and the second virtual point o2′ is a third connection line, and the connection line between the fourth connection point o4 and the second virtual point o2′ is a fourth connection line, the length of the third connection line may be denoted as 121, and the length of the fourth connection line may be denoted as 122. In this case, the length of the third connection line and the length of the fourth connection line can embody the size of the cut triangle, and the larger the size, the larger the offset amount of the center of the second sub-pixel 20 with respect to the center of the second virtual shape 20′, the larger the distances from the second sub-pixel 20 to other sub-pixels adjacent to the second sub-pixel 20 so that lateral leakage currents between the second sub-pixel 20 and the other sub-pixels adjacent to the second sub-pixel 20 can be smaller; but when the cut triangle has a relatively large size, the display brightness of the multiple second sub-pixels 20 is reduced so that color deviation can be caused, and the overall display brightness of the display panel can be even reduced. For example, 1/20≤121/L21≤2/5, and 1/20≤122/L22≤2/5.
In conclusion, in this embodiment, the ratio between the minimum distance 121 from the third connection point o3 to the second virtual point o2′ and the length L21 of the third virtual edge 21′ is limited to be greater than or equal to 1/40 and less than or equal to 1/2, and the ratio between the minimum distance 122 from the fourth connection point o4 to the second virtual point o2′ and the length L22 of the fourth virtual edge 22′ is limited to be greater than or equal to 1/40 and less than or equal to 1/2 so that on the premise that the multiple second sub-pixels 20 are ensured to have enough display brightness, enough small lateral leakage currents can be provided between the second sub-pixel 20 and the other sub-pixels adjacent to the second sub-pixel 20, thereby improving the overall display effect of the display panel.
In an optional embodiment, 121=122, that is, the cut triangle may be an isosceles triangle so that the multiple second sub-pixels 20 can be ensured to have uniform chamfers, thereby improving the light emission effect of the multiple second sub-pixels 20.
It is to be understood that the multiple first sub-pixels and the multiple second sub-pixels have different emitted colors so that the multiple first sub-pixels and the multiple second sub-pixels can have different light emission efficiencies, and to ensure the consistent display brightness of the multiple first sub-pixels and the multiple second sub-pixels, when the sub-pixels are designed, the first sub-pixel and the second sub-pixel are configured to have different sizes, for example, for an organic light-emitting diode display panel, when the emitted color of the multiple first sub-pixels is red, and the emitted color of the multiple second sub-pixels is blue, the designed size of the multiple first sub-pixels is greater than the designed size of the multiple second sub-pixels. Meanwhile, since an image in response to a color requires to be displayed on the display panel, the display brightness of the multiple first sub-pixels, the display brightness of the multiple second sub-pixels and the display brightness of the multiple third sub-pixels require to be set separately so that an image of a corresponding color can be presented after the mixture of light rays emitted by the multiple first sub-pixels, the multiple second sub-pixels and the multiple third sub-pixels that have corresponding display brightness. Therefore, when the sizes of a triangle cut in the first sub-pixel and/or a triangle cut in the second sub-pixel are relatively large, or when the sizes of triangles cut in the first sub-pixel and the second sub-pixel are not uniform, the display brightness of the multiple first sub-pixels and/or the multiple second sub-pixels is caused to have a relatively large decrease so that the image of the corresponding color cannot be presented due to color deviation of the display panel.
Referring to
In an optional embodiment, 111/L11=121/L21, and 112/L12=122/L22. In this way, the proportion of the size of the triangle cut in the first sub-pixel 10 in the first virtual shape 10′ can be ensured to be consistent with the proportion of the size of the triangle cut in the second sub-pixel 20 in the second virtual shape 20′ so that the decreases in the display brightness of the multiple first sub-pixels 10 and the multiple second sub-pixels 20 can remain consistent, thereby preventing the display color deviation and improving the display brightness of the display panel.
It is to be understood that the preceding solely exemplifies that only one first edge 11 of the first sub-pixel 10 does not coincide with the first virtual shape 10′, and in the embodiment of the present disclosure, other edges of the first sub-pixel 10 may also not coincide with the first virtual shape 10′. Similarly, the preceding solely exemplifies that one second edge 21 of the second sub-pixel 20 does not coincide with the second virtual shape 20′, and in the embodiment of the present disclosure, other edges of the second sub-pixel 20 may also not coincide with the second virtual shape 20′. This is not specifically limited in the embodiment of the present disclosure on the premise that the core inventive points of the present disclosure can be achieved.
As a feasible embodiment,
In the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the included angle α2 between the eleventh edge 16 and the twelfth edge 26 is an included angle between extension lines of the eleventh edge 16 and the twelfth edge 26, or when an included angle between the eleventh edge 16 and the first direction X is denoted as α21, and an included angle between the twelfth edge 26 and the first direction X is denoted as α22, the included angle α2 between the eleventh edge 16 and the twelfth edge 26 may be equal to |α21-α22|, that is, that the included angle α2 is provided between the eleventh edge 16 and the twelfth edge 26 does not indicate that the eleventh edge 16 intersects the twelfth edge 26. In other words, eleventh edges 16 of all first sub-pixels 10 do not overlap twelfth edges 26 of all second sub-pixels 20.
In an embodiment, the value range of α2 is 0°≤α2≤45° so that in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the eleventh edge 16 and the twelfth edge 26 can be parallel to each other or can have a relatively small included angle, that is, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the included angle α2 between the eleventh edge 16 and the twelfth edge 26 may be 0°, 5°, 10°, 20°, 30°, 40°, or 45°. On the premise that the core inventive points of the embodiment of the present disclosure can be achieved, this is not specifically limited in the embodiment of the present disclosure. In an optional embodiment, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, extension directions of the first edge 11 and the second edge 21 are roughly the same, and extension directions of the eleventh edge 16 and the twelfth edge 26 are roughly the same so that the shapes of the multiple first sub-pixels 10 and the multiple second sub-pixels 20 can remain consistent. In this way, in the at least part of adjacent first sub-pixels 10 and second sub-pixels 20, the value range of the included angle α1 between the first edge 11 and the second edge 12 is 0°≤α1≤45°, and the value range of the included angle α2 between the eleventh edge 16 and the twelfth edge 26 is 0°≤α2≤ 45° so that the shapes of the multiple first sub-pixels 10 and the shapes of the multiple second sub-pixels 20 can be similar, and so that the adjacent first sub-pixel 10 and second sub-pixel 20 can have consistent display light emission situations, thereby facilitating the improvement in the display uniformity of the adjacent first sub-pixel 10 and second sub-pixel 20 and the display effect of the display panel 100.
In addition, when the eleventh edge 16 of the first sub-pixel 10 does not coincide with the first virtual shape 10′, a relatively large distance is provided from a sub-pixel located on one side of the eleventh edge 16 of the first sub-pixel 10 to the first sub-pixel 10 so that a lateral leakage current distance from the first sub-pixel 10 to the sub-pixel located on the side of the eleventh edge 16 of the first sub-pixel 10 can be relatively large, facilitating the reduction in a lateral leakage current between the first sub-pixel 10 and the sub-pixel located on the side of the eleventh edge 16 of the first sub-pixel 10; when the twelfth edge 26 of the second sub-pixel 20 does not coincide with the second virtual shape 20′, a relatively large distance is provided from a sub-pixel located on one side of the twelfth edge 26 of the second sub-pixel 20 to the second sub-pixel 20 so that a lateral leakage current distance from the second sub-pixel 20 to the sub-pixel located on the side of the twelfth edge 26 of the second sub-pixel 20 can be relatively large, facilitating the reduction in a lateral leakage current between the second sub-pixel 20 and the sub-pixel located on the side of the twelfth edge 26 of the second sub-pixel 20; in this way, the eleventh edge 16 of the first sub-pixel 10 does not coincide with the first virtual shape 10′, and the twelfth edge 26 of the second sub-pixel 20 does not coincide with the second virtual shape so that the undesired light emission of the sub-pixels and the optical crosstalk can be further improved, thereby ensuring a relatively high display light emission accuracy of the multiple first sub-pixels 10 and the multiple second sub-pixels 20 and further facilitating the improvement in the display quality of the display panel.
In an optional embodiment, the length of the first edge 11 is denoted as L31, the length of the eleventh edge 16 is denoted as L32, the length of the second edge 21 is denoted as L41, the length of the twelfth edge 26 is denoted as L42, and 1/10<(L31+L32)/(L41+L42)≤1.
When two edges of the first sub-pixel 10 do not coincide with the first virtual shape 10′, that is, the first edge 11 and the eleventh edge 16, the sizes of the two edges can embody the sizes of two chamfers in the first sub-pixel 10, and the larger the sum of the sizes of the two chamfers, the larger the decrease in the display brightness of the first sub-pixel 10. Similarly, when two edges of the second sub-pixel 20 do not coincide with the second virtual shape 20′, that is, the second edge 21 and the twelfth edge 26, the sizes of the two edges can embody the sizes of two chamfers in the second sub-pixel 20, and the larger the sum of the sizes of the two chamfers, and the larger the decrease in the display brightness of the second sub-pixel 20. In addition, when the decreases in the display brightness of the first sub-pixel 10 and the second sub-pixel 20 are different, the display panel may have color deviation so that the display effect of the display panel can be affected.
In this embodiment, the sum (L31+L32) of the first edge 11 and the eleventh edge 16 is used for indicating the sum of the sizes of chamfers cut in the first sub-pixel 10, the sum (L41+L42) of the second edge 21 and the twelfth edge 26 is used for indicating the sum of the sizes of chamfers cut in the second sub-pixel 20, and the value range of (L31+L32)/(L41+L42) is configured to be greater than or equal to 1/10 and less than or equal to 1 so that the sizes of chamfers of the first sub-pixel 10 and chamfers of the second sub-pixel 20 can have a relatively small difference, and so that the decreases in the display brightness of the first sub-pixel 10 and the second sub-pixel 20 can remain consistent, thereby ensuring that the first sub-pixel 10 and the second sub-pixel 20 can have consistent display brightness, preventing the display color deviation and improving the display effect of the display panel. For example, 1/2≤ (L31+L32)/(L41+L42)≤4/5.
It is to be understood that the preceding solely exemplifies a situation in which in the same first sub-pixel 10, an included angle may be present between the first edge 11 and the eleventh edge, and the size of the included angle may be designed according to actual requirements, that is, extension lines of the first edge and the eleventh edge may intersect. In an optional embodiment, when the first edge and the eleventh edge are two opposite edges, a relatively small included angle may be present between the first edge and the eleventh edge so that extension directions of the first edge and the eleventh edge can be roughly the same. Similarly, in the same second sub-pixel 20, an included angle may be present between the second edge and the twelfth edge, and the size of the included angle may be designed according to actual requirements, that is, extension lines of the second edge and the twelfth edge may intersect. In an optional embodiment, when the second edge and the twelfth edge are two opposite edges, a relatively small included angle may be present between the second edge and the twelfth edge so that extension directions of the second edge and the twelfth edge can be roughly the same.
In an optional embodiment, the first edge 11 is parallel to the eleventh edge 16 in the same first sub-pixel 10, and the second edge 21 is parallel to the twelfth edge 26 in the same second sub-pixel 20. In this way, the first edge 11 and the eleventh edge 16 may be two opposite edges in the first sub-pixel 10 so that the first sub-pixel 10 can have the same light emission effect in two opposite directions, thereby facilitating the improvement in the display light emission consistency of the first sub-pixel 10 in the two opposite directions. Similarly, the second edge 21 and the twelfth edge 26 may also be two opposite edges in the second sub-pixel 20 so that the second sub-pixel 20 can also have the same light emission effect in two opposite directions, thereby facilitating the improvement in the display light emission consistency of the second sub-pixel 20 in the two opposite directions.

For example, α3 may be 41°, 45°, or 49°. Optionally, α3=45°. In this way, the extension direction of the long axis of the support column 40 is pointed toward a respective third sub-pixel 30 so that an included angle between a short edge (which is perpendicular to the extension direction) of the support column 40 and a corresponding overlapped virtual edge can be very small. After the non-opening region between the multiple first sub-pixels 10 and the multiple second sub-pixels 20 are provided with the multiple support columns 40, the manufacturing yield and display effect can be improved, and high pixels per inch (PPI) of the display panel can be achieved.
