Description

Pixel arrangement structure, display panel and display device

Technical Field

The application relates to the technical field of display, in particular to a pixel arrangement structure, a display panel and display equipment.

Background

Currently, with the continuous development of display technology, the demand for resolution of display devices is increasing. When the resolution of the display device is equivalent to the resolution level of human eyes, the mode that the conventional red (R), green (G) and blue (B) three-color sub-pixels simply define one pixel can be changed by utilizing the difference of the human eyes to the resolution of the sub-pixels with different colors. Namely: the sub-pixels with insensitive colors at certain positions and resolutions are shared among different pixels, and the same pixel resolution performance capability is realized by simulation with relatively fewer sub-pixels, so that the preparation process difficulty and the preparation cost of the display device are reduced. Among them, a Pixel unit formed by an exclusive Sub-Pixel and a peripheral shared Sub-Pixel is often referred to as an SPR virtual Pixel by Rendering (SPR) the shared Sub-Pixel.

At present, for the SPR virtual pixel arrangement structure applied to the existing display device, especially for the SPR virtual pixel in the existing AMOLED (Active-Matrix Organic Light-Emitting Diode) applied to the mobile display device, due to the specific shape difference of the sub-pixel Light spot profile in the adjacent virtual pixel, the border line of the picture displayed by the pixel unit has large periodic fluctuation, which easily causes the display picture to have the condition of wave feeling and granular feeling, thereby affecting the viewing experience of the user.

The inventor of the present application has studied and found that, for the SPR virtual pixel arrangement in an Active-Matrix Organic Light-Emitting Diode (AMOLED) currently applied to a mobile display device, due to a specific shape difference of a sub-pixel Light spot profile in adjacent virtual pixels, a boundary line of a picture displayed by a pixel unit has a large periodic fluctuation, which causes a situation that a fine line or an edge in a specific direction in the displayed picture has a discontinuous feeling such as a wave or a particle, thereby affecting the viewing experience of a user.

Moreover, the relative number of R sub-pixels and B sub-pixels in the SPR virtual pixel arrangement of the existing AMOLED is small, when a relatively uniform background is displayed, for example, for a near-white background, because the luminance of the B sub-pixel is low, the small number of B sub-pixels easily causes dark spots in the near-white background during the luminance modulation process, and further causes a relatively obvious granular sensation in the near-white background, thereby further affecting the viewing experience of a user.

The application provides a pixel arrangement structure, a display panel and a display device, which aim to solve the technical problems in the prior art.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.

An embodiment of the present application provides a pixel arrangement structure, a schematic structural diagram of the pixel arrangement structure is shown in fig. 1, and the pixel arrangement structure includes: a plurality of first subpixel columns 100 and a plurality of second subpixel columns 200, the first subpixel columns 100 and the second subpixel columns 200 being alternately arranged along the first direction.

The first sub-pixel column 100 comprises a plurality of first sub-pixels 10 and a plurality of second sub-pixels 20, the luminance center of each first sub-pixel 10 in the first sub-pixel column 100 is collinear with the luminance center of each second sub-pixel 20, and two second sub-pixels 20 are arranged between two adjacent first sub-pixels 10; in two adjacent first sub-pixel columns 100, a distance d along a second direction between a straight line where a first edge of a first sub-pixel 10 in one first sub-pixel column 100 is located and a first edge of a second sub-pixel 20 closest to the first sub-pixel 10 in the other first sub-pixel column 100 is within a first set distance range, and the second direction is perpendicular to the first direction; the second sub-pixel column 200 includes a plurality of third sub-pixels 30.

In the pixel arrangement structure provided in the embodiment of the present application, the first subpixel columns 100 and the second subpixel columns 200 are alternately arranged along the first direction, the luminance center of each first subpixel 10 in the first subpixel column 100 and the luminance center of each second subpixel 20 are arranged on the same line, and the distance d along the second direction between the straight line where the first edge of the first subpixel 10 in one first subpixel column 100 in the two adjacent first subpixel columns 100 is located and the first edge of the second subpixel 20 closest to the first subpixel 10 in the other first subpixel column 100 is within the first set distance range. Therefore, in the adjacent pixel units along the first direction, the distance between the straight line where the first edge of the first sub-pixel 10 of one pixel unit is located and the first edge of the second sub-pixel 20 of the other pixel unit along the second direction is within the first set distance range. And then the fluctuation range of the boundary lines of the display picture can be reduced, the probability of the display picture appearing wavy and granular feelings can be reduced, and the watching experience of a user is guaranteed.

In the embodiment of the present application, as shown in fig. 1, two first subpixel columns 100 and three second subpixel columns 200 are alternately arranged along the first direction, for the convenience of intuitively understanding the first subpixel columns 100 and the second subpixel columns 200, a dashed-line frame is shown in fig. 1, and a dashed-line frame does not exist in an actual product.

As shown in fig. 1, the first sub-pixel column 100 includes a plurality of first sub-pixels 10 and a plurality of second sub-pixels 20, and two second sub-pixels 20 are disposed between two adjacent first sub-pixels 10; the second sub-pixel column 200 includes a plurality of third sub-pixels 30. In two adjacent first sub-pixel columns 100, a distance d along the second direction between a straight line where the first edge of the first sub-pixel 10 in one first sub-pixel column 100 is located and the first edge of the second sub-pixel 20 closest to the first sub-pixel 10 in the other first sub-pixel column 100 is within a first set distance range.

It should be noted that, in the embodiment of the present application, as shown in fig. 1 and 2, the first edge of the first sub-pixel 10 refers to the outermost boundary of the first sub-pixel 10 in the second direction. Similarly, the first side of the second subpixel 20 refers to the outermost boundary of the first subpixel 10 in the second direction. In the embodiment of the present application, since the first sub-pixel 10 and the second sub-pixel 20 are regular in shape, the first edge is a straight line segment, and the extending direction of the first edge is parallel to the first direction.

In the case where the shape of the first subpixel 10 is irregular, the straight line where the first side of the first subpixel 10 is located is a tangent line parallel to the first direction in the outermost boundary of the first subpixel 10 in the second direction. Similarly, in the case where the shape of the second sub-pixel 20 is irregular, the straight line where the first edge of the first sub-pixel 10 is located is a tangent line parallel to the first direction in the outermost boundary of the second sub-pixel 20 along the second direction.

Optionally, in this embodiment of the application, the first sub-pixel 10 is a red sub-pixel, that is, light emitted by the first sub-pixel 10 is red; the second sub-pixel 20 is a green sub-pixel, that is, the light emitted by the second sub-pixel 20 is green; the third sub-pixel 30 is a blue sub-pixel, i.e. the light emitted by the third sub-pixel 30 is blue.

It is understood by those skilled in the art that the green and red sub-pixels play a major role in the perceived center position of the luminance of the pixel. Therefore, in the embodiment of the present application, in two adjacent first subpixel columns 100, a distance d along the second direction between a straight line where the first edge of the first subpixel 10 in one first subpixel column 100 is located and the first edge of the second subpixel 20 closest to the first subpixel 10 in the other first subpixel column 100 in the first set distance range can enable the fluctuation range of the boundary line of the display screen along the first direction to be within the set range, so that the fluctuation range of the boundary line of the display screen can be ensured, the probability of the display screen appearing wavy and grainy can be reduced, and the viewing experience of the user can be ensured.

In order to facilitate understanding of the pixel arrangement structure provided in the present application, the connecting line of the luminance centers of the sub-pixels and the middle dividing line of a part of the sub-pixels in the pixel arrangement structure shown in fig. 1 are shown by dashed lines, and the dashed line frame is removed, so as to obtain the structure shown in fig. 2.

Alternatively, as shown in fig. 2, the luminance center of each first sub-pixel 10 and the luminance center of each second sub-pixel 20 in each first sub-pixel column 100 are connected and indicated by a dotted line; connecting the brightness centers of the third sub-pixels 30 in each second sub-pixel column 200, which is indicated by a dotted line; connecting the brightness centers of the third sub-pixels 30 in the adjacent second sub-pixel column 200, which is indicated by a dotted line; the bisector of the first subpixel 10 is indicated by a dotted line, thereby forming a field grid region, and four field grids are formed in fig. 2.

It should be noted that, in the case where the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are regular in shape, the luminance centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 all coincide with the respective geometric centers.

In the embodiment of the present application, as shown in fig. 2, the luminance center of each first sub-pixel 10 and the luminance center of each second sub-pixel 20 in the first sub-pixel column 100 are collinear and parallel to the second direction; two second sub-pixels 20 are disposed between two adjacent first sub-pixels 10.

It should be noted that the pixel arrangement shown in fig. 1 and 2 is a minimal repeating unit, i.e., a display panel is implemented to include a plurality of the pixel arrangement shown in fig. 1 and 2.

In an embodiment of the present application, as shown in fig. 1 and fig. 2, two adjacent first subpixel columns 100 are disposed in a staggered manner, and a straight line, in which the luminance center of the first subpixel 10 in one first subpixel column 100 and the luminance center of the first subpixel 10 adjacent to the first subpixel 10 in the other first subpixel column 100, is located, has a set angle with the first direction. Optionally, the value of the set included angle is related to the distance d.

In the embodiment of the present application, two adjacent first subpixel columns 100 are disposed in a staggered manner, so that a distance d along the second direction between a straight line where the first edge of the first subpixel 10 in one first subpixel column 100 is located and the first edge of the second subpixel 20 closest to the first subpixel 10 in the other first subpixel column 100 is within a first set distance range. The fluctuation range of the boundary lines of the display picture can be reduced, the probability of the display picture appearing in a wavy sense and a granular sense can be reduced, and the watching experience of a user is guaranteed.

In one embodiment of the present application, as shown in fig. 2, the first distance D1 of the first sub-pixel column 100 is less than the second distance D2 along the second direction; the first distance D1 is the distance between the luminance centers of two second subpixels 20 disposed between two adjacent first subpixels 10; the second distance D2 is the distance between the luminance centers of the second sub-pixels 20 located at both sides of a first sub-pixel 10.

Optionally, the second distance D2 is 1.25 to 1.6 times the pixel pitch, the second distance D2 includes an end value, and the pixel pitch is the size of one grid shown in fig. 2; the sum of the first distance D1 and the second distance D2 is equal to twice the pixel pitch.

In one embodiment of the present application, as shown in fig. 1 and 2, of two adjacent second sub-pixel columns 200, one second sub-pixel column 200 and the other second sub-pixel column 200 are symmetrical with respect to the first sub-pixel column 100.

In two adjacent second sub-pixel columns 200, the third sub-pixel 30 of one second sub-pixel column 200 and the third sub-pixel 30 closest to the third sub-pixel 30 in the other second sub-pixel column 200 are symmetrically arranged about a straight line where the luminance center of the first sub-pixel 10 and the luminance center of the second sub-pixel 20 are located.

Optionally, along the first direction, one third sub-pixel 30 is disposed on each of two sides of each second sub-pixel 20, and the two third sub-pixels 30 are symmetrical with respect to the first sub-pixel column 100 where the second sub-pixel 20 is located. Therefore, the number of the third sub-pixels 30 in the pixel arrangement structure can be increased, the density of the third sub-pixels 30 in the pixel arrangement structure can be increased, when a relatively uniform background is displayed, the problem that dark spots of the third sub-pixels 30 in the brightness modulation process cause obvious granular sensation in the background can be solved, the bright spot phenomenon in a display picture can be reduced, the granular sensation of the display picture can be reduced, and the watching experience of a user is further guaranteed. Alternatively, as shown in fig. 1 and 2, the number ratio of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 located within the four checkered squares is 1:2: 2.

In one embodiment of the present application, as shown in fig. 2, the pitch of two adjacent first sub-pixel columns 100 along the first direction is one pixel pitch; the pitch of two adjacent second sub-pixel columns 200 along the first direction is also one pixel pitch. In two adjacent first sub-pixel columns 100, a distance between a bisectrix of a first sub-pixel 10 in one first sub-pixel column 100 and a bisectrix of a first sub-pixel 10 closest to the first sub-pixel 10 in the other first sub-pixel column 100 along a second direction is a pixel pitch; that is, in two adjacent first sub-pixel columns 100, the first sub-pixel 10 in one first sub-pixel column 100 is staggered from the first sub-pixel 10 closest to the first sub-pixel 10 in the other first sub-pixel column 100 by a pixel pitch; i.e. two adjacent first sub-pixel columns 100, are staggered by one pixel pitch in the second direction.

In the embodiment of the present application, as shown in fig. 2, in two adjacent first sub-pixel columns 100, a middle point of a connecting line of luminance centers of two second sub-pixels 20 located between two adjacent first sub-pixels 10 in one first sub-pixel column 100 and a connecting line of luminance centers of one first sub-pixel 10 in the other first sub-pixel column 100 extend in a direction perpendicular to the second direction. Thereby making the distribution of the luminance centers of the first sub-pixel 10 and the second sub-pixel 20 in the pixel arrangement more uniform.

Alternatively, as shown in fig. 2, in the second sub-pixel column 200, the luminance centers of the third sub-pixels 30 are uniformly distributed along the second direction. And the extension direction of the middle point of the connecting line of the brightness centers of two adjacent third sub-pixels 30 of any one second sub-pixel column 200 and the connecting line of the brightness centers of one first sub-pixel 10 in the adjacent first sub-pixel column 100 is perpendicular to the second direction. Therefore, the brightness centers of the third sub-pixels 30 in the pixel arrangement structure are uniformly distributed, so that the problem that the dark spots of the third sub-pixels 30 in the brightness modulation process cause obvious granular sensation in the background is solved, and the watching experience of a user is further guaranteed.

Optionally, on the premise of ensuring that the luminance centers of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 in the pixel arrangement structure are uniformly distributed, in order to ensure the aperture ratio, a stripe-shaped first sub-pixel 10 extending along the first direction and a stripe-shaped second sub-pixel 20 extending along the second direction as shown in fig. 1 and fig. 2 are formed; that is, the size of the first sub-pixel 10 along the first direction is much larger than the size of the second sub-pixel 20 along the second direction, and the size of the second sub-pixel 20 along the second direction is much larger than the size of the first sub-pixel along the first direction.

In one embodiment of the present application, as shown in fig. 1 and 2, in the first sub-pixel column 100, the second sub-pixels 20 located at two sides of the first sub-pixel 10 along the first direction are symmetrical with respect to the first sub-pixel 10, that is, the distance between one second sub-pixel 20 and the first sub-pixel 10 is equal to the distance between the other second sub-pixel 20 and the first sub-pixel 10.

In an embodiment of the present application, as shown in fig. 3, in two adjacent first sub-pixel columns 100, along the second direction, a projection of a first sub-pixel 10 of one first sub-pixel column 100 onto a first sub-pixel 10 of another first sub-pixel column 100 covers at least a part of the first sub-pixel 10.

In one embodiment of the present application, as shown in fig. 1 to 4, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 have at least one of a hexagonal shape and a quadrangular shape. Alternatively, as shown in fig. 1 and 2, the first sub-pixel 10 has a hexagonal shape, the second sub-pixel 20 has a rectangular shape, and the third sub-pixel 30 has a parallelogram shape. Alternatively, as shown in fig. 3, the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are all rectangular in shape. Alternatively, as shown in fig. 4, the first sub-pixel 10 has a shape of a centrosymmetric octagon, the second sub-pixel 20 has a shape of a hexagon, and the third sub-pixel 30 has a shape of a diamond.

Those skilled in the art can adapt the actual requirements. The first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 having different shapes are not limited to the shapes shown in fig. 1 to 4 in the embodiments of the present application.

In one embodiment of the present application, the pixel arrangement structure further includes a plurality of first pixel units 301 and a plurality of second pixel units 302; the first pixel unit 301 and the second pixel unit 302 are alternately arranged along the first direction and the second direction; the first pixel unit 301 and the second pixel unit 302 each include a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30, and a distance d along the second direction between a straight line where a first side of the first sub-pixel 10 of the first pixel unit 301 is located and a first side of the second sub-pixel 20 of the second pixel unit 302 adjacent to each other along the first direction is within a first set distance range.

In the embodiment of the present application, as shown in fig. 5 and 6, the first pixel unit 301 and the second pixel unit 302 are alternately arranged along the first direction and the second direction; the first pixel unit 301 and the second pixel unit 302 each include a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30, and a distance d along the second direction between a straight line where a first side of the first sub-pixel 10 of the first pixel unit 301 is located and a first side of the second sub-pixel 20 of the second pixel unit 302 adjacent to each other along the first direction is within a first set distance range. Therefore, the fluctuation range of the display frame along the boundary line in the first direction is within the set range, the fluctuation range of the boundary line of the display frame can be guaranteed, the probability of the display frame appearing wavy and granular feelings can be reduced, and the watching experience of a user is guaranteed.

As shown in fig. 6, in the first pixel unit 301 and the second pixel unit 302, the luminance centers of the first sub-pixel 10 and the second sub-pixel 20 are collinear, so that the fluctuation range of the display screen along the boundary line in the second direction can be visually improved, the probability of the display screen appearing wavy and grainy can be reduced, and the viewing experience of the user can be guaranteed.

In one embodiment of the present application, in the first pixel unit 301 and the second pixel unit 302, the first sub-pixel column 100 in which the first sub-pixel 10 and the second sub-pixel 20 are located, and the second sub-pixel column 200 in which the third sub-pixel 30 is located are sequentially arranged along the first direction; the first sub-pixel 10 and the second sub-pixel 20 in the first pixel unit 301 are sequentially arranged along the second direction, and the second sub-pixel 20 and the first sub-pixel 10 in the second pixel unit 302 are sequentially arranged along the second direction; the first sub-pixel 10 of the first pixel unit 301 is shared by the second pixel units 302 adjacent to each other in the second direction.

It should be noted that in the embodiment of the present application, since the sub-pixels in the first pixel unit 301 and the second pixel unit 302 are shared, the first pixel unit 301 and the second pixel unit 302 are not pixels in a strict sense, and the first pixel unit 301 and the second pixel unit 302 may be referred to as a virtual pixel. The third pixel unit 401, the fourth pixel unit 402, the fifth pixel unit 501 and the sixth pixel unit 502, which are mentioned later, are also all dummy pixels.

In the embodiment of the present application, as shown in fig. 5 and 6, a first pixel unit 301 and a second pixel unit 302 are marked by a dashed line frame. Since the first sub-pixel 10 is shared by the first pixel unit 301 and the second pixel unit 302, the gray scales of the first sub-pixel 10 in the first pixel unit 301 and the second pixel unit 302 are both 50%, and the gray scales of the second sub-pixel 20 and the third sub-pixel 30 are both 100%.
