Description
Technical Field
The invention relates to the technical field of display, in particular to a display panel and a display device thereof.
Background
With the development of technology, a simple rectangular display device cannot meet the requirements of consumers, and display devices with various shapes, such as circular shapes, arc shapes and the like, are produced. A display device that is not rectangular in shape may be referred to as an odd-shaped display device.
At present, sub-pixels at the edge of the irregular display device are generally cut into a specific shape, or are shielded by a black rectangle to form a specific shape, so that the sub-pixels can be disposed at the irregular edge. For example, in an arc-shaped display device, the sub-pixels arranged at the arc-shaped positions may be arranged in the corresponding arc shape, so that the sub-pixels can be arranged at the arc-shaped positions.
However, the difference between the opening area of each sub-pixel arranged at the edge of the special-shaped display device and the opening area of the conventional rectangular sub-pixel results in poor display effect of the display unit comprising the special-shaped sub-pixel during display, such as color cast and the like.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that although the terms first, second, third, etc. may be used to describe the color sub-pixels in the embodiments of the present invention, the color sub-pixels should not be limited to these terms. These terms are only used to distinguish color sub-pixels from each other. For example, the first color sub-pixel may also be referred to as a second color sub-pixel, and similarly, the second color sub-pixel may also be referred to as a first color sub-pixel without departing from the scope of embodiments of the present invention.
It should be noted that the terms "upper", "lower", "left", "right", and the like used in the description of the embodiments of the present invention are used in the angle shown in the drawings, and should not be construed as limiting the embodiments of the present invention. In addition, in this context, it is also to be understood that when an element is referred to as being "on" or "under" another element, it can be directly formed on "or" under "the other element or be indirectly formed on" or "under" the other element through an intermediate element.
Before explaining the technical solution of this embodiment in detail, the special-shaped display area and the special-shaped sub-pixels related to this embodiment are briefly described:
generally, the display area of the display panel is designed to be rectangular, and most of mobile phones are rectangular in shape, for example. With the rise of wearable devices, the personalized requirements of users are met, and the shapes of display panels are more and more diversified, such as circular, fan-shaped, arc-shaped, groove-shaped and the like. In this embodiment, a region in which the display region is not rectangular is referred to as a special-shaped display region, for example, the second display region in this embodiment. However, it cannot be understood that the technical solution related to this embodiment only has the special-shaped display area, and the display area in this embodiment may include the special-shaped display area, or may include a conventional display area other than the special-shaped display area, such as the first display area.
Further, the pixel unit to be disposed in the normal display area (first display area) in the present embodiment may be referred to as a normal pixel unit, for example, the first pixel unit in the present embodiment, because its shape is a normal rectangle. Similarly, the shape of the sub-pixel is a regular rectangle, which can be referred to as a regular sub-pixel, for example, the first color sub-pixel, the second color sub-pixel and the third color sub-pixel included in the first pixel unit in this embodiment can be referred to as a regular sub-pixel. Since the special-shaped display area necessarily includes an edge that is not perpendicular to other edges, the special-shaped edge may be referred to as a special-shaped edge, and a pixel unit near the special-shaped edge is limited by the special-shaped edge, and has a shape different from that of a conventional pixel unit, that is, the pixel unit near the special-shaped edge is not rectangular, and may be referred to as a special-shaped pixel unit, for example, the second pixel unit in the embodiment. Similarly, the shape of the sub-pixel is not a regular rectangle, and may be referred to as a special-shaped sub-pixel, for example, the sub-pixel included in the second pixel unit in this embodiment is not a rectangle.
In addition, the aperture area of a pixel unit may be understood as the sum of the aperture areas of all the sub-pixels constituting the pixel unit. The aperture area of each sub-pixel is an area excluding the wiring of the sub-pixel and the area of the sub-pixel blocked by the black matrix. The ratio of the opening area of the sub-pixel to the area occupied by each sub-pixel is called the aperture ratio, and can also be understood as the ratio of the area of the effective light-transmitting area of the sub-pixel to the total area. Illustratively, the opening area of the special-shaped sub-pixel represents the area of the effective light-transmitting region of the special-shaped sub-pixel, and the opening area of the conventional sub-pixel represents the area of the effective light-transmitting region of the conventional sub-pixel.
In this embodiment, as shown in fig. 1, which is a schematic structural diagram of a display panel provided in the embodiment of the present invention, the display panel 100 includes:
a display area 3 and a non-display area 4, wherein at least one first display area 1 and at least one second display area 2 are arranged within the display area 3.
The first display area 1 comprises at least one first pixel unit 10, wherein the first pixel unit 10 comprises a first color sub-pixel 101, a second color sub-pixel 102 and a third color sub-pixel 103; as shown in fig. 1, the shape of the first display area is rectangular, which can be understood as that the first display area is a normal display area, and the first pixel unit 10 and the first color sub-pixel 101, the second color sub-pixel 102 and the third color sub-pixel 103 included in the first pixel unit 10 are all rectangular, which can be understood as that the first pixel unit 10 is a normal pixel unit.
The second display area 2 is a convex area facing away from the first display area 1 with respect to the first display area 1, and the second display area 2 includes a connecting edge 23, and the connecting edge 23 is not perpendicular to the remaining edges of the second display area 2. As shown in fig. 1, the second display area 2 is semicircular, and the connecting edge 23 is an arc line of the second display area 2, and the arc line (connecting edge) is not perpendicular to the rest of the second display area 2, and the other edge at this time can be understood as an overlapping edge of the second display area 2 and the first display area 1, and the overlapping edge is a horizontal straight line.
In this embodiment, the second display area 2 may be understood as a special-shaped display area, which is not rectangular in shape. Wherein the second display area 2 necessarily has at least one edge that is not perpendicular to the remaining edges, this edge may be referred to as a shaped edge, and the connecting edge 23 may be understood as a shaped edge in this example.
The second display area 2 comprises at least one second pixel cell 20, the second pixel cell 20 is adjacent to the connecting edge 23, and the shape of the edge of the second pixel cell 20 adjacent to the connecting edge 23 is the same as the shape of the connecting edge 23. The second display area 2 is an odd-shaped display area including an odd-shaped edge (connecting edge), and the shape of one edge of the second pixel unit 20 is the same as the shape of the odd-shaped edge (connecting edge), that is, the shape of the second pixel unit 20 is also not rectangular, and the second pixel unit can be understood as an odd-shaped pixel unit in this embodiment.
The second pixel unit 20 includes at least one first color sub-pixel 101, at least one second color sub-pixel 102, and at least one third color sub-pixel 103, in which the first color sub-pixel 101 and the second color sub-pixel 102 are arranged in a row direction, and the third color sub-pixel 103 and the first color sub-pixel 101 are arranged in a column direction in the second pixel unit 20.
In the prior art, the pixel unit close to the irregular edge has color cast in the display process due to different opening areas of the sub-pixels included in the pixel unit. For example, taking a pixel cell near the shaped edge as an example, the pixel cell includes sub-pixels that may include only two colors, e.g., a red sub-pixel and a green sub-pixel, so that when white light is displayed, color cast occurs.
In this embodiment, the second display area 2 is a protruding area that is far away from the first display area 1 relative to the second display area 2, and the connecting edge 23 included in the second display area 2 is not perpendicular to the other edges of the second display area 2, which can be understood as that the connecting edge 23 is an irregular edge; the second pixel unit 20 is adjacent to the connecting edge (the irregular edge), and the second pixel unit 20 is limited by the irregular edge (the connecting edge), and at this time, if the second pixel unit 20 is still rectangular, the opening area is relatively small, and in order to pursue a larger opening area, the shape cannot be necessarily rectangular, that is, the opening area of the second pixel unit 20 is the largest when the shape of the edge of the second pixel unit 20 adjacent to the irregular edge (the connecting edge) is the same as the shape of the irregular edge (the connecting edge). While seeking the maximum opening area, the second pixel unit 20 arranges the first color sub-pixels 101 and the second color sub-pixels 102 along rows, and the third color sub-pixels 103 and the first color sub-pixels 101 along column directions, that is, the second pixel unit 20 includes three sub-pixels of different colors only occupying two columns, that is, three sub-pixels of different colors are placed on the area occupied by two sub-pixels in the prior art, so that color cast does not occur in the display process of the embodiment, and the display effect is improved.
It should be noted that, as an example, the second display area 2 shown in fig. 1 includes only two sides, and in fact, the present embodiment does not particularly limit the number of sides enclosing the second display area, as long as the connecting sides of the second display area are not perpendicular to the other sides. Similarly, although fig. 1 shows that the shape of two sub-pixels in the second pixel unit is not rectangular, it cannot be understood that the shape of two sub-pixels in the second pixel unit is not rectangular, as long as the shape of the sub-pixels adjacent to the connecting side in the second pixel unit is not rectangular, and the number of sub-pixels that are not rectangular is not particularly limited.
In an implementation manner, as shown in fig. 2, which is another schematic structural diagram of the display panel provided in the embodiment of the present invention, the second pixel unit 20 includes a first color sub-pixel 101, a second color sub-pixel 102, and a third color sub-pixel 103, wherein a ratio of opening areas of three sub-pixels of different colors in the second pixel unit 20 is the same as a ratio of opening areas of three sub-pixels of different colors in the first pixel unit 10.
It is understood that the first pixel unit 10 disposed in the first display region 1 is a conventional pixel unit, which can realize a normal display function, and in combination with the above embodiment, the second pixel unit 20 is an irregular pixel unit, in which case the opening area of the second pixel unit (irregular pixel unit) is inevitably not equal to the opening area of the first pixel unit (conventional pixel unit). In this embodiment, the ratio of the opening areas of the three sub-pixels with different colors in the special-shaped pixel unit (the second pixel unit) is the same as the ratio of the opening areas of the three sub-pixels with different colors in the conventional pixel unit (the first pixel unit), that is, the display effect of the second pixel unit (the special-shaped pixel unit) is the same as the display effect of the first pixel unit (the conventional pixel unit), that is, the second pixel unit does not generate color shift during the display process, thereby avoiding the color shift at the special-shaped edge.
Even if the odd-shaped pixel unit close to the odd-shaped edge includes three sub-pixels with different colors, for example, a red sub-pixel, a green sub-pixel and a blue sub-pixel, in the display process, since the three sub-pixels are limited differently by the odd-shaped edge, the aperture areas of the three sub-pixels are different greatly, and the problem of color cast is also caused when white light is displayed. In this embodiment, the ratio of the opening areas of the three sub-pixels with different colors in the special-shaped pixel unit (the second pixel unit) arranged on the connecting edge is the same as the ratio of the opening areas of the three sub-pixels with different colors in the conventional pixel unit (the first display unit), so that the display effect of the special-shaped pixel unit (the second pixel unit) is the same as that of the conventional pixel unit, and the problem of color cast is solved.
It should be noted that, in this embodiment, the aperture areas of the three sub-pixels with different colors in the second pixel unit may be equal or different, as long as the ratio is the same as the aperture area ratio of the three sub-pixels with different colors in the first pixel unit (regular pixel unit). In other words, the aperture areas of the three sub-pixels with different colors are the same, but a specific example is the same ratio.
In an implementation manner, as shown in fig. 3, which is another schematic structural diagram of the display panel provided in the embodiment of the present invention, the second pixel unit 20 includes a first color sub-pixel 101, a second color sub-pixel 102, and two third color sub-pixels 103, the first color sub-pixel 101, the second color sub-pixel 102, and the third color sub-pixel 103 are arranged along a row direction, and the other third color sub-pixel 103 and the first color sub-pixel 101 are arranged along a column direction.
In addition, it should be noted that, as an example, fig. 2 and fig. 3 both show two second display regions 2, and taking fig. 3 as an example, the second pixel units 20 in the second display regions on the left and right sides are symmetrically arranged, in fact, the arrangement of the second pixel units in this embodiment is not limited thereto, and for example, still taking fig. 3 as an example, the arrangement of each sub-pixel in the second pixel unit in the second display region 2 on the right side may be identical to that of the second pixel unit in the second display region on the left side.
Under the limitation of the special-shaped edge, in order to pursue the maximum opening area of the special-shaped pixel unit adjacent to the special-shaped edge, the shape of the edge of at least one sub-pixel included in the special-shaped pixel unit is the same as that of the special-shaped edge, but in the process of displaying, the color deviation can occur due to the difference of the opening areas of a plurality of sub-pixels included in the special-shaped pixel unit. For example, the irregular pixel unit comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel, and the opening areas of the three sub-pixels with different colors are not uniform, so that color cast is generated. In this embodiment, the second pixel unit is limited by the connecting edge (the special-shaped edge), and among the three sub-pixels with different colors, the opening area of the sub-pixel with one color is the smallest and the opening area of the sub-pixel with one color is the largest, so that the second pixel unit (the special-shaped pixel unit) does not have color cast during the display process, the second pixel unit (the special-shaped pixel unit) can divide part of the opening area in the sub-pixel with the largest opening area into the sub-pixel with the smallest opening area, so that the second pixel unit includes four sub-pixels in three rows, that is, the opening area of the sub-pixel with the smallest opening area is increased, and the color cast at the special-shaped edge is improved.
Further, in order to avoid color shift at the irregular edge, the ratio of the opening areas of the three sub-pixels with different colors in the second pixel unit may be the same as the ratio of the opening areas of the three sub-pixels with different colors in the first pixel unit.
In the prior art, limited by the special-shaped edge, the opening area of the special-shaped pixel unit adjacent to the special-shaped edge is inevitably not equal to the opening area of the conventional pixel unit, at this time, in order to prevent color shift at the special-shaped edge, the opening area of the sub-pixel included in the special-shaped pixel unit can be set to be consistent, inevitably, the opening area is kept consistent with the sub-pixel with the minimum opening area, that is, the opening area can be sacrificed by the special-shaped sub-pixel unit, and the problem of color shift is solved, but at this time, the opening area of the special-shaped pixel unit is further reduced, so that the light transmission effect of the special-shaped pixel unit is poor. Illustratively, the irregular pixel unit comprises a red sub-pixel, a blue sub-pixel and a green sub-pixel, wherein the opening area of the red sub-pixel is 5, the opening area of the blue sub-pixel is 8, and the opening area of the green sub-pixel is 11, and the opening area of the irregular pixel unit is the sum 24 of the opening areas of the three sub-pixels with different colors. However, in order to prevent color shift at the irregular edge, the opening area of each of the blue sub-pixel and the green sub-pixel is reduced to 5, and at this time, the opening area of the irregular pixel unit is 15, so that the light transmission effect of the irregular pixel unit is obviously reduced due to the reduction of the opening area of the irregular pixel.
In this embodiment, still taking the opening area of the special-shaped pixel unit (the second pixel unit) as 24 as an example, one of the two red sub-pixels has an opening area of 5, the other one of the two red sub-pixels has an opening area of 3, the opening area of the blue sub-pixel is still 8, and the opening area of the green sub-pixel is 8, that is, in this embodiment, the ratio of the opening areas of the three sub-pixels with different colors included in the second pixel unit (the special-shaped pixel unit) is the same as the ratio of the opening areas of the three sub-pixels with different colors included in the first pixel unit (the conventional pixel unit), so that the color shift problem at the special-shaped edge can be significantly improved, and meanwhile, the opening area of the second pixel unit (the special-shaped pixel unit) at the special-shaped edge is not reduced, so that the light transmission amount at the special-shaped edge is not reduced.
In the present embodiment, the second pixel unit (the special-shaped pixel unit) improves the color shift at the special-shaped edge while maximizing the maximum opening area, and does not reduce the amount of light transmission at the special-shaped edge (the connecting edge).
In another embodiment, on the basis of the above embodiment, in order to make the ratio of the aperture areas of the three different color sub-pixels in the second pixel unit to the aperture area ratio of the three different color sub-pixels in the first pixel unit (regular pixel unit) the first color sub-pixel, the second color sub-pixel and the two third color sub-pixels included in the second pixel unit are arranged in the following manner:
first, as shown in fig. 4, which is another schematic structural diagram of the display panel according to the embodiment of the present invention, the second pixel unit 20 is sequentially provided with a third color sub-pixel 103, a second color sub-pixel 102 and a first color sub-pixel 101 along the row direction, a width b of the second color sub-pixel 102 along the row direction is greater than a width a of the first color sub-pixel 101 along the row direction and a width c of the third color sub-pixel along the row direction, and a width of another third color sub-pixel 103 (in the same column as the first color sub-pixel) along the row direction is the same as the width a of the first color sub-pixel 101 along the row direction. At this time, in order to balance the ratios of the opening areas of the three sub-pixels of different colors in the second pixel unit 20, which are the same as the ratios of the opening areas of the three sub-pixels of different colors in the first pixel unit 10 (conventional pixel unit), the bottom edge 1021 of the second color sub-pixel 102 having a larger width in the row direction is not on the same straight line as the bottom edge 1011 of the first color sub-pixel and the bottom edge 1031 of the third color sub-pixel in the same row. Specifically, the second color sub-pixel 102 in the second pixel unit 20 is close to the side of the first pixel unit 10, and is not on the same straight line with the side of the first color sub-pixel 101 and the third color sub-pixel 103 in the same row in the second pixel unit 20.
In addition, in the second pixel unit, the width of the first color sub-pixel 101 along the row direction is set to be the same as the width of the two third color sub-pixels 101 along the row direction, so that the arrangement of the two sub-pixels is regular, and the process is simple.
In this embodiment, the second color sub-pixel in the second pixel unit 20 is close to the edge of the first pixel unit 10, and can be understood as the bottom edge 1021 of the second color sub-pixel. In addition, the width a of the first color sub-pixel 101 and the width c of the third color sub-pixel 103 in the same row as the first color sub-pixel 101 may be equal or different along the row direction. Preferably, the values of a and c are equal in this embodiment. Naturally, in the present embodiment, there may be a plurality of first pixel units 10 disposed in the first display region 1, and the number of the first pixel units is not particularly limited in the present embodiment. In this embodiment, a plurality of first pixel units 10 may be arranged on the display panel in an array. Similarly, the number of the second pixel units disposed in the second display area 2 may be plural, and the number is not particularly limited in this example.
Second, as shown in fig. 5, which is another structural schematic diagram of the display panel according to the embodiment of the present invention, the second pixel unit 20 is sequentially disposed with a third color sub-pixel 103, a second color sub-pixel 102, and a first color sub-pixel 101 along the row direction, and widths of the two third color sub-pixels 103 along the row direction are equal to a width a of the first color sub-pixel along the row direction. Moreover, the second color sub-pixel 102 in the second pixel unit 20 is close to the side of the first pixel unit 10, and is on the same straight line with the sides of the first color sub-pixel 101 and the third color sub-pixel 103 in the same row in the second pixel unit 20, that is, the bottom edge 1011 of the first color sub-pixel, the bottom edge 1021 of the second color sub-pixel, and the bottom edge 1031 of the third color sub-pixel in the same row are disposed on the same straight line. At this time, in order to balance the ratio of the opening areas of the three sub-pixels of different colors in the second pixel unit 20, which is the same as the ratio of the opening areas of the three sub-pixels of different colors in the first pixel unit 10 (conventional pixel unit), the width of the second color sub-pixel 102 with a larger opening area along the row direction can be relatively reduced, that is, the width b of the second color sub-pixel 102 along the row direction is smaller than the width a of the first color sub-pixel 101 along the row direction.
In an implementation manner, as shown in fig. 6, which is another schematic structural diagram of the display panel provided in the embodiment of the present invention, the second display area 2 further includes a first edge 21 and a second edge 22, and the first edge 21 and the second edge 22 are connected by a connecting edge 23; the extending direction of the first side 21 and the extending direction of the second side 22 are perpendicular to each other, and the connecting side 23 is not parallel to the extending direction of the first side 21 and the extending direction of the second side 22. In addition, in the present embodiment, the connecting edge may be an arc line as shown in fig. 6, or may be a straight line.
In this embodiment, each of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel is one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Therefore, on the basis of taking the pixel unit as a display unit, the display function can be realized.
In order to better understand the present solution, the following liquid crystal display panel is taken as an example to describe the display principle of the display panel:
as shown in fig. 7, fig. 8 and fig. 9, fig. 7 is another schematic structural diagram of a display panel according to an embodiment of the present invention, fig. 8 is a schematic display principle diagram of the display panel according to the embodiment of the present invention, fig. 9 is a cross-sectional view of an AA' position in fig. 8 according to the embodiment of the present invention, the display panel 100 may be a liquid crystal display panel, and the liquid crystal display panel includes an array substrate 62 and a color filter substrate 61 that are oppositely disposed, and a liquid crystal layer 63 located between the array substrate 62 and the color filter substrate 61.
