Description

Technical Field

[0001] This disclosure relates to the field of display technology, specifically to a pixel unit, a pixel repeating arrangement unit, and a display panel. Background Technology

[0002] With the continuous development of display technology, the resolution of displays is constantly improving, enabling better image display effects. However, current display panels, limited by pixel graphic design, often exhibit severe jagged edges and color fringing in their displayed images, especially text, resulting in a poor user experience. Summary of the Invention

[0003] In view of this, the present disclosure provides a pixel unit, a pixel repeating arrangement unit, and a display panel, which alleviates or eliminates the jagged edge phenomenon by staggering the sub-pixels in the pixel unit.

[0004] The first aspect of this disclosure provides a pixel unit comprising two first sub-pixels, two second sub-pixels, and one third sub-pixel. The first sub-pixels, second sub-pixels, and third sub-pixels have different preset emission colors. The two first sub-pixels and two second sub-pixels are distributed around the third sub-pixel, and the two second sub-pixels are located on both sides of a straight line defined by the centroids of the two first sub-pixels.

[0005] In the above scheme, the sub-pixels in the pixel unit are arranged in an interlaced manner, thereby alleviating the jaggedness of the pixel unit when it is displayed. In addition, it can avoid the situation where the first sub-pixel or the second sub-pixel is arranged in a row or column alone, so as to avoid the appearance of colored edges in the displayed image. Furthermore, when arranging pixels, the degree of interlacing of the sub-pixels included in each pixel unit can be increased to further alleviate the edge jaggedness of the displayed image, thereby improving the display effect.

[0006] In one specific implementation of the first aspect of this disclosure, two first sub-pixels are located on opposite sides of a third sub-pixel, and two second sub-pixels are located on the other opposite sides of the third sub-pixel. For example, further, the two first sub-pixels are located on opposite sides of two opposite pixel edges of the third sub-pixel, and the two second sub-pixels are located on opposite sides of another two opposite pixel edges of the third sub-pixel. For example, even further, the pixel edges of the corresponding two first sub-pixels of the third sub-pixel are a first pixel edge and a second pixel edge, and the pixel edges of the corresponding two second sub-pixels of the third sub-pixel are a third pixel edge and a fourth pixel edge. The first pixel edge and the third pixel edge are adjacent, the second pixel edge and the fourth pixel edge are adjacent, and the first pixel edge, the third pixel edge, the second pixel edge, and the fourth pixel edge are arranged sequentially in the circumferential direction of the third sub-pixel. For example, even further, the second pixel edge and the third pixel edge are connected by at least one pixel edge, and the first pixel edge and the fourth pixel edge are connected by at least one pixel edge.

[0007] In one specific implementation of the first aspect of this disclosure, one of the two first sub-pixels is connected to one of the two second sub-pixels to form a group, and the other of the two first sub-pixels is connected to the other of the two second sub-pixels to form another group, with the first and second sub-pixels of different groups spaced apart from each other.

[0008] In the above scheme, the first and second sub-pixels are arranged in an alternating manner in groups, thereby further alleviating the problems of jagged edges and color fringes in the displayed image; in addition, the fabrication of part of the structure of the third sub-pixel (such as the light-emitting layer) can share the same opening of the mask, so as to reduce the precision requirements of the mask and the alignment accuracy requirements of the corresponding fabrication process, thereby reducing costs.

[0009] In one specific implementation of the first aspect of this disclosure, the preset emission wavelength of the first sub-pixel is less than the preset emission wavelength of the second sub-pixel, but greater than the preset emission wavelength of the third sub-pixel. For example, further, the first sub-pixel is a green sub-pixel, the second sub-pixel is a red sub-pixel, and the third sub-pixel is a blue sub-pixel.

[0010] In one specific implementation of the first aspect of this disclosure, the opening area of ​​the third sub-pixel can be designed to be larger than the opening areas of the first sub-pixel and the second sub-pixel.

[0011] In one specific implementation of the first aspect of this disclosure, the planar shapes of the first sub-pixel, the second sub-pixel, and the third sub-pixel are all polygons. The first sub-pixel and the second sub-pixel each share a pixel edge of the third sub-pixel, and at least two opposite pixel edges of the third sub-pixel are not shared with either the first sub-pixel or the second sub-pixel.

[0012] In one specific implementation of the first aspect of this disclosure, the planar shapes of the first sub-pixel, the second sub-pixel, and the third sub-pixel are all polygons. The pixel edges of the third sub-pixel opposite to the first sub-pixel are shared pixel edges of the third sub-pixel and the first sub-pixel. The pixel edges of the third sub-pixel opposite to the second sub-pixel are shared pixel edges of the third sub-pixel and the second sub-pixel. Furthermore, at least two opposite pixel edges of the third sub-pixel are not shared with any pixel edge of either the first sub-pixel or the second sub-pixel. For example, further, the two first sub-pixels are centrally symmetric about the centroid of the third sub-pixel; and / or, the two second sub-pixels are centrally symmetric about the centroid of the third sub-pixel.

[0013] In the above scheme, the light emission of the pixel unit is relatively uniform, so as to improve the image display effect.

[0014] In one specific implementation of the first aspect of this disclosure, the planar shape of the third sub-pixel is hexagonal, and the planar shapes of the first and second sub-pixels are both quadrilaterals. Each of the first and second sub-pixels shares a pixel edge with the third sub-pixel. The two pixel edges shared by the third sub-pixel and the first sub-pixel are opposite each other, and the two pixel edges shared by the third sub-pixel and the second sub-pixel are opposite each other, but the third sub-pixel is not opposite to any pixel edge shared by the first and second sub-pixels. For example, further, the opposite edges of the hexagons are parallel to each other.

[0015] In one specific implementation of the first aspect of this disclosure, the hexagon is formed by joining a rectangle and two isosceles triangles, with two opposite sides of the rectangle sharing the base of the isosceles triangle. Two sides of the rectangle not shared with the isosceles triangle are shared with the pixel edge of a first sub-pixel, and one side of each isosceles triangle is shared with the pixel edge of a second sub-pixel.

[0016] In one specific implementation of the first aspect of this disclosure, the vertex angle of the isosceles triangle is a right angle, and / or, the lengths of the two sides of the rectangle not shared with the isosceles triangle are half the length of the base of the isosceles triangle.

[0017] In one specific implementation of the first aspect of this disclosure, the planar shape of the first sub-pixel is a rectangle, the planar shape of the second sub-pixel is a right trapezoid, the pixel side shared by the second sub-pixel and the first sub-pixel is the top side of the right trapezoid, and the pixel side shared by the second sub-pixel and the third sub-pixel is the sloping side of the right trapezoid. For example, further, the planar shape of the first sub-pixel is a square.

[0018] In the above scheme, the ratio of the areas of the two first sub-pixels, the two second sub-pixels, and the two third sub-pixels is 2:3:4. This ratio can compensate for the differences in light emission efficiency, lifespan, etc. of various sub-pixels, so as to ensure the display effect of the displayed image while making the product with the pixel unit (such as the display panel described below) have a longer service life.

[0019] In another specific implementation of the first aspect of this disclosure, the planar shape of the first sub-pixel is rectangular, the planar shape of the second sub-pixel is parallelogram, and the pixel edges shared by the second sub-pixel and the pixel edges shared by the third sub-pixel are connected. For example, further, the planar shape of the first sub-pixel is square.

[0020] In the above scheme, the ratio of the area of ​​the two first sub-pixels, the area of ​​the two second sub-pixels, and the area of ​​the two third sub-pixels is 1:1:2. When the preset emission wavelength of the third sub-pixel is relatively small (for example, it emits blue light), this ratio can compensate for the shortcomings of the third sub-pixel in terms of light emission efficiency and lifespan, so as to ensure the display effect of the displayed image while making the product with this pixel unit (such as the display panel described below) have a longer service life.

[0021] In another specific implementation of the first aspect of this disclosure, the planar shape of the first sub-pixel is a right trapezoid, the pixel side shared by the first sub-pixel and the third sub-pixel is the right leg of the right trapezoid, the pixel side shared by the second sub-pixel and the first sub-pixel is the base of the right trapezoid, and the pixel side of the second sub-pixel that is opposite to the first sub-pixel it is opposite to the pixel side it is opposite to the pixel side it is opposite to the first sub-pixel it is opposite to. For example, further, the lengths of the top side and the right leg of the right trapezoid are equal; and / or, the ratio of the lengths of the top side and the base of the right trapezoid is 2 / 3, and the lengths of the pixel side shared by the second sub-pixel and the first sub-pixel are equal to the lengths of the top side of the right trapezoid.

[0022] In the above scheme, the staggered arrangement of pixel units can be ensured without gaps between adjacent pixel units, thereby alleviating the problem of jagged edges in the displayed image.

[0023] A second aspect of this disclosure provides a pixel repeating arrangement unit, which includes at least one pixel unit as described in the first aspect above.

[0024] In one specific implementation of the second aspect of this disclosure, each pixel repeating arrangement unit includes two pixel units, wherein a straight line in one pixel unit defined by the centroids of the two first sub-pixels is parallel to a straight line in the other pixel unit defined by the centroids of the two first sub-pixels.

[0025] In one specific implementation of the second aspect of this disclosure, in each pixel repeating unit, a straight line defined by the centroids of two first sub-pixels in the pixel unit passes through a second sub-pixel in another pixel unit.

[0026] In one specific implementation of the second aspect of this disclosure, two first sub-pixels located between two third sub-pixels are centrally symmetrical; and / or, two second sub-pixels located between two third sub-pixels are centrally symmetrical.

[0027] This disclosure provides a display panel including a display area in which a plurality of pixel repeating units as described in the second aspect are arranged. The plurality of pixel repeating units are arranged in multiple rows and columns, and in each pixel repeating unit, a straight line defined by the centroids of two first sub-pixels is parallel to the row direction. In the same row, any straight line in each pixel repeating unit coincides with a straight line in another pixel repeating unit. In the same column, for any pixel repeating unit located at a non-endpoint (with pixel repeating units arranged on its front and rear sides), the pixel edge of the third sub-pixel in each pixel unit that is not opposite to the first and second sub-pixels is opposite to the pixel edge of the third sub-pixel in an adjacent pixel repeating unit that is not adjacent to the first and second sub-pixels, such that a straight line in each pixel repeating unit that is perpendicular to the row direction and passes through the centroid of the third sub-pixel is parallel to and spaced apart from a straight line in an adjacent pixel repeating unit that is perpendicular to the row direction and passes through the centroid of the third sub-pixel.

[0045] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0046] The display area of ​​a display panel is arranged with sub-pixels. Adjacent sub-pixels (which can be called sub-pixels) with different emitting colors constitute large pixels. By controlling the grayscale of each sub-pixel within a large pixel, the large pixel can emit light of any color; that is, the large pixel is the smallest independent unit for image display. A large number of large pixels are needed in the display panel to achieve image display. In the display panel, large pixels are repeatedly arrayed, which inevitably results in some large pixels and even sub-pixels appearing in multiple rows and columns. Under this design, the edges of the displayed image will appear jagged; furthermore, if the preset emitting color of each row and / or column of sub-pixels is the same, colored edges will appear in the displayed image (e.g., monochrome or colored lines not included in the preset display image), leading to poor display.

[0047] Embodiments of this disclosure provide a pixel unit, a pixel repeating arrangement unit, and a display panel to at least solve the aforementioned technical problems. The pixel unit includes two first sub-pixels, two second sub-pixels, and one third sub-pixel. The first, second, and third sub-pixels have different preset emitted light colors. The two first and two second sub-pixels are distributed around the third sub-pixel, and the two second sub-pixels are located on either side of a straight line defined by the centroids of the two first sub-pixels. In this way, the two first sub-pixels and two second sub-pixels in the pixel unit are located on opposite sides of the third sub-pixel. This is equivalent to splitting a large area of ​​one first sub-pixel and one second sub-pixel into two smaller areas of one first sub-pixel and two second sub-pixels, which are placed on both sides of the third sub-pixel. This allows the sub-pixels in the pixel unit to be arranged in an interlaced manner, thereby alleviating the jagged edges when the pixel unit is displayed. In addition, after arranging the pixels based on this pixel unit, it is possible to avoid the situation where the first sub-pixel or the second sub-pixel is arranged in a row or column alone. That is, each row or column of sub-pixels will not contain only the first sub-pixel or the second sub-pixel, thus avoiding colored edges in the displayed image. Furthermore, while maintaining the connection between adjacent pixel units, the row and column directions of the pixel unit arrangement can intersect but not be perpendicular, thereby further increasing the degree of interlacing of the sub-pixels included in each pixel unit, further alleviating the jagged edges of the displayed image, and thus improving the display effect.

[0048] The structure of the pixel unit, pixel repeating unit, and display panel according to at least one embodiment of the present disclosure will now be described with reference to the accompanying drawings. It should be noted that, since both the pixel unit and the pixel repeating unit are used to constitute the pixel structure of the display panel, in these embodiments, the structure of the display panel will be described first, followed by a simultaneous description of the structure of the pixel unit and the pixel repeating unit included in the display panel.

[0049] Furthermore, in these accompanying drawings, a spatial Cartesian coordinate system is established with the surface of the display panel as a reference to illustrate the position of each element in the display panel and the arrangement of pixel units and their sub-pixels. In this spatial Cartesian coordinate system, the X-axis and Y-axis are parallel to the surface of the display panel, and the X-axis is parallel to the line determined by the centroids of the two first sub-pixels in the pixel unit, while the Z-axis is perpendicular to the surface of the display panel.

[0050] like Figures 1-7 As shown, the display panel 10 includes a display area 11 and a border area 12 surrounding the display area 11. Pixel structures are arranged in the display area 11 to achieve image display, and at least one pixel unit 100 constitutes a pixel repeating arrangement unit 200. Figure 3 Each pixel repeating unit 200 consists of two pixel units 100. The pixel repeating units 200 are arranged in multiple rows and columns to form the pixel structure of the display area. The row direction is the extension direction of the straight line L1. In the same row, any straight line L1 in each pixel repeating unit 200 will coincide with a straight line L1 in other pixel repeating units 200. The column direction is the extension direction of line L2. In the same column, for any pixel repeating unit 200 located at a non-endpoint (with pixel repeating units 200 arranged on both its front and back sides), the pixel edge of the third sub-pixel 130 in each pixel unit 100 that is not adjacent to the first sub-pixel 110 and the second sub-pixel 120 is opposite to the pixel edge of the third sub-pixel 130 in the adjacent pixel repeating unit 200 that is not adjacent to the first sub-pixel 110 and the second sub-pixel 120. 200 is such that the line L4 in each pixel repeating unit that is perpendicular to the row direction and passes through the centroid of the third sub-pixel is parallel to and spaced apart from the line L4 in the adjacent pixel repeating unit 200 that is perpendicular to the row direction and passes through the centroid of the third sub-pixel 130. The line connecting the centroids of the adjacent third sub-pixels 130 determines line L2. The border area 12 can be used to lay out traces leading out from the display area 11. For example, the border area 12 may include a bonding area 13, in which multiple lap terminals (or pads) may be provided. The traces led out from the display area 11 may be gathered in the bonding area 13 and connected to the lap terminals to be electrically connected to external circuits (such as flexible circuit boards with driver chips) through the lap terminals.

[0051] Specifically, such as Figures 2-4As shown, in pixel unit 100, there are two first sub-pixels 110, two second sub-pixels 120, and one third sub-pixel 130. The preset emitted light colors of the first sub-pixels 110, second sub-pixels 120, and third sub-pixels 130 are different. The two first sub-pixels 110 and the two second sub-pixels 120 are arranged alternately around the third sub-pixel 130, such that the straight line L3 (parallel to the X-axis) determined by the centroids of the two first sub-pixels 110 passes through the third sub-pixel 130. The two second sub-pixels 120 are respectively arranged on both sides of the straight line L3. Thus, in the circumference (e.g., clockwise) surrounding the third sub-pixel 130, the first sub-pixels 110, second sub-pixels 120, first sub-pixels 110, and second sub-pixels 120 are arranged in sequence, and in the direction of the straight line L4 perpendicular to the straight line L3 (parallel to the Y-axis), the two second sub-pixels 120 are staggered. Thus, in each pixel unit, the number of the three types of sub-pixels is designed in a 2:2:1 ratio. While maintaining the overall pixel unit area unchanged, this effectively reduces the design area of ​​each first sub-pixel 110 and second sub-pixel 120, and disperses the emission areas of the light corresponding to the color of the first sub-pixel 110 and the light corresponding to the color of the second sub-pixel 120, thereby alleviating the jagged edge problem during image display. Furthermore, as... Figure 5 As shown, in the case of Figure 5 After the pixel units 100 are combined into pixel repeating arrangement units 200 and repeated arrangement is performed based on pixel repeating arrangement units 200 to form a pixel structure, the first sub-pixel 110 and the second sub-pixel 120 cannot be arranged into a row or column alone. That is, the first sub-pixel and the second sub-pixel will be arranged in an alternating manner, thereby eliminating the color edge problem that may exist when displaying the image.

[0052] For example, in the pixel units provided in the embodiments of this disclosure, such as Figure 6 and Figure 5 As shown, two first sub-pixels 110 are located on two opposite sides of a third sub-pixel 130, and two second sub-pixels 120 are also located on the other two opposite sides of the third sub-pixel 130.

[0053] For example, such as Figure 6 and Figure 5 As shown, the two first sub-pixels 110 are respectively located on opposite sides of two opposing pixel edges (e.g., the first pixel edge 131 and the second pixel edge 132 described below), and the two second sub-pixels 120 are respectively located on opposite sides of another two opposing pixel edges (e.g., the third pixel edge 133 and the fourth pixel edge 134 described below), that is, the first sub-pixels 110 and the second sub-pixels 120 are both set to correspond to different pixel edges of the third sub-pixel 130.

[0054] For example, such as Figure 6and Figure 5 As shown, the pixel edges of the two corresponding first sub-pixels 110 of the third sub-pixel 130 are the first pixel edge 131 and the second pixel edge 132, and the pixel edges of the two corresponding second sub-pixels 120 of the third sub-pixel 130 are the third pixel edge 133 and the fourth pixel edge 134. The first pixel edge 131 and the third pixel edge 133 are adjacent, and the second pixel edge 132 and the fourth pixel edge 134 are adjacent. In the circumferential direction of the third sub-pixel 130, the first pixel edge 131, the third pixel edge 133, the second pixel edge 132 and the fourth pixel edge 134 are arranged in sequence. The two first sub-pixels 110 and the two second sub-pixels 120 corresponding to these first pixel edges 131, the third pixel edge 133, the second pixel edge 132 and the fourth pixel edge 134 respectively also have the same arrangement relationship.

[0055] For example, such as Figure 6 and Figure 4 As shown, the second pixel edge 132 and the third pixel edge 133 are connected by at least one pixel edge (e.g., the sixth pixel edge 136 described below), and the first pixel edge 131 and the fourth pixel edge 134 are connected by at least one pixel edge (e.g., the fifth pixel edge 135 described below). Thus, the pixel edges of the third sub-pixel 130 that are not opposite to the first sub-pixel 110 and the second sub-pixel 120 can be used to splice the pixel unit with other pixel units.

[0056] In the embodiments of this disclosure, the edge of the third sub-pixel in the pixel unit will be connected with the first sub-pixel and the second sub-pixel. Here, the size of the part used for connection in the edge of the third sub-pixel is not limited and can be designed according to the actual process requirements.

[0057] For example, in some embodiments of this disclosure, in each pixel unit, the edge of the third sub-pixel is used to mate with the first sub-pixel and the second sub-pixel.

[0058] For example, in other embodiments of this disclosure, in each pixel unit, only a portion of the edge of the third sub-pixel is used to connect with the first and second sub-pixels. Thus, when pixel units are used to form pixel repeating units and further arranged into pixel structures, third sub-pixels in adjacent but different pixel repeating units can connect, reducing the manufacturing process requirements of the third sub-pixels and allowing them to have a larger aperture ratio. Furthermore, after the pixel repeating units are arranged into multiple rows and columns, the row and column directions intersect but are not perpendicular, further increasing the degree of overlap between the first and second sub-pixels to further eliminate the color edge problem. For example, as... Figure 2As shown, the first sub-pixel 110 and the second sub-pixel 120 are connected in pairs to form two groups. Each group includes one first sub-pixel 110 and one second sub-pixel 120. The first sub-pixel 110 and the second sub-pixel 120 in the same group are connected. The two groups are separated by a third sub-pixel 130, that is, the first sub-pixel 110 and the second sub-pixel 120 of different groups are separated from each other. Thus, as... Figure 3 and Figure 2 As shown, at the interval between the two groups, the edge of the third sub-pixel 1330 in each pixel unit 100 can be used to align with the edge of the third sub-pixel 130 of another adjacent pixel unit 100 located in the same column (located at the interval between the two groups of the pixel unit), thereby causing the first sub-pixels 110 and the second sub-pixels 120 in the entire pixel structure to be arranged in an alternating grouped manner, in order to further alleviate the problems of edge jaggedness and color fringing in the displayed image; in addition, the above design can allow the third sub-pixels 130 to be arranged in a row or column alone (e.g., Figure 5 The arrangement shown is in multiple columns, which allows the fabrication of some structures of the third sub-pixel 130 (such as the light-emitting layer) to share the same opening of the mask, thereby reducing the precision requirements of the mask and the alignment accuracy requirements of the corresponding fabrication process, and thus reducing costs.

[0059] Each sub-pixel can include an effective light-emitting area (e.g., Figure 5 As shown, each subpixel's area within the dashed box and its boundary area (such as...) Figures 1-7 As shown, each sub-pixel's area is located outside the dashed box. The effective light-emitting area is used to emit light to form the displayed image, while the boundary area defines the light-emitting boundaries of sub-pixels of different colors. The "aperture ratio" can be the ratio of the area of ​​the effective light-emitting area to the area of ​​the sub-pixel (the sum of the areas of the effective light-emitting area and the boundary area). Furthermore, during the fabrication of the display panel, a mask is used to pattern the corresponding film structure to determine the range of the effective light-emitting area and the boundary area. Thus, the precision of the mask (e.g., the size of the aperture used for patterning) directly limits the sub-pixel density (higher density results in higher resolution). When some sub-pixels with the same preset light-emitting color (e.g., the third sub-pixel) are adjacent, the apertures of the mask used to pattern these sub-pixels can be connected, thereby reducing the precision requirements of the mask.

[0060] The specific structure of subpixels will be described below through some specific embodiments to explain the technical principle that adjacent subpixels with the same preset emission color will increase the aperture ratio. It should be noted that in the embodiments of this disclosure, the specific structure of the subpixel unit can be designed according to the type of display panel, and the type of display panel is not limited here. Therefore, in these embodiments, the structure of the subpixels is described for several different types of display panels.

[0061] For example, in some embodiments of this disclosure, such as Figure 7 As shown, the display panel 10 is an organic light-emitting display panel (OLED panel). The display panel 10 may include a substrate 210 and a display functional layer located on the substrate 210. The display functional layer includes a plurality of organic light-emitting devices 230 and a pixel defining layer 220 for defining the organic light-emitting devices 230. The organic light-emitting device 230 includes an anode 231, a light-emitting functional layer 233, and a cathode 232 sequentially stacked on the substrate 210. The light-emitting functional layer 233 includes a light-emitting layer. The pixel defining layer 220 includes an opening corresponding to each organic light-emitting device 230. Each opening exposes the anode 231 of the corresponding organic light-emitting device 230 and is used to accommodate the light-emitting functional layer 233 (e.g., the light-emitting layer is located in the opening). The substrate 210 may be an array substrate, which includes a driving circuit layer. The portion of the driving circuit layer located in the display area includes a plurality of pixel driving circuits 211 connected to the anode. Figure 7 Only the thin-film transistors included in the pixel driving circuit 211 are shown in the image. The area where the organic light-emitting device 230 is located is the effective light-emitting area of ​​each sub-pixel, while the boundary area of ​​the sub-pixel is actually the area where the pixel defining layer 220 is distributed.

[0062] As described above, the position of the organic light-emitting device 230 is actually determined by the opening in the pixel defining layer 220, while... Figure 2 In the fabrication process of the display panel shown, a full-layer pixel-defining material film is deposited on the substrate 210, and then patterned (using a mask) to form a pixel-defining layer 220 with multiple openings. During this process, if sub-pixels with the same preset light color are spaced apart, the anode position error and the alignment error between the anode and the mask need to be considered. The anode needs to be designed to be larger than the openings, and the pixel-defining layer 220 between the openings needs a certain design width to ensure that the openings and the anode 231 can be aligned. Increasing this design width will correspondingly reduce the design area of ​​the openings, thereby reducing the "aperture ratio" of the sub-pixels. Figure 3 and Figure 5When the third sub-pixels 130 with the same preset emission color are connected, the light-emitting functional layers in the connected third sub-pixels have the same structure and can be designed to share a light-emitting functional layer. That is, it is not necessary to consider the width of the pixel boundary layer 130 between the organic light-emitting devices 230 in the two connected third sub-pixels 130, or the pixel boundary layer 130 is not set between the organic light-emitting devices 230 in the two connected third sub-pixels 130, so that the organic light-emitting devices 230 in the two third sub-pixels 130 are located in the same opening, thereby allowing the organic light-emitting devices 230 of the third sub-pixel 130 to have a larger design area, that is, increasing the "aperture ratio" of the third sub-pixel.

[0063] For example, in some other embodiments of this disclosure, the display panel can be a liquid crystal display panel, which includes an array substrate and a counter substrate disposed opposite each other, with liquid crystal filling the space between the array substrate and the counter substrate. Control electrodes are disposed on the array substrate and the counter substrate to form an electric field. By controlling the electric field, the state of the liquid crystal is controlled to control the polarization state of light (light provided by an external device such as a backlight module), and a polarizer is used to control the emitted light brightness. A color filter (CF) and a black matrix (BM) are disposed on the light-emitting side of the display panel to control the color and emission boundary of the emitted light, thereby achieving display. The color filter includes multiple color filters, which constitute the body of a sub-pixel. When the color filter and the black matrix are on the same layer, the range of the color filter is defined by the black matrix, and the opening of the black matrix is ​​used to define the position of the color filter. In this case, the color filter acts as the effective light-emitting area of ​​the sub-pixel. When the color filter and the black matrix are on different layers, the portion of the color filter that overlaps with the opening of the black matrix serves as the effective light-emitting area. For example, the preparation method of the black matrix may include coating, deposition or photolithography using a mask. When sub-pixels with the same preset light color are connected, the openings of the mask corresponding to these sub-pixels (such as color filters) can be connected to each other, thereby giving the sub-pixels a larger aperture ratio.

[0064] For example, in some embodiments of this disclosure, the display panel can be a display structure of the electronic paper type, and the sub-pixels can be cavity structures containing electronic ink. For example, the electronic ink can be a small ball containing ink, the ball carrying a charge, and electrodes are disposed in the cavity. An electric field is generated by the electrodes to control the distribution of the ball, thereby realizing image display. When sub-pixels with the same preset emission color are connected, the two sub-pixels can share a cavity, thereby giving the sub-pixels a larger aperture ratio.

[0065] In the embodiments of this disclosure, the preset emitted light colors (different colors of light have different wavelengths) of the first sub-pixel, the second sub-pixel, and the third sub-pixel are not limited and can be designed according to actual display requirements. For example, the preset emitted light wavelength of the first sub-pixel is less than the preset emitted light wavelength of the second sub-pixel and greater than the preset emitted light wavelength of the third sub-pixel. For example, see 2~ Figure 5 As shown, the first sub-pixel 110 is the green sub-pixel G, the second sub-pixel 120 is the red sub-pixel R, and the third sub-pixel 130 is the blue sub-pixel B.

[0066] In at least one embodiment of the pixel unit provided in this disclosure, two first sub-pixels are centrally symmetrical about the centroid of a third sub-pixel; and / or, two second sub-pixels are centrally symmetrical about the centroid of a third sub-pixel. Thus, the light emission of the pixel unit is relatively uniform, thereby improving the image display effect. For example, as... Figure 5 As shown, the third sub-pixel 130 is a centrally symmetrical shape, with its centroid being the center of symmetry. Figure 5 (The position of the letter "B" in the middle), the straight line L3 passes through the center of symmetry of the third sub-pixel 130. Thus, the two first sub-pixels 110 are centrally symmetrical about this center of symmetry, and the two second sub-pixels 120 are also centrally symmetrical about this center of symmetry.

[0067] In the embodiments of this disclosure, the overall shape of the pixel unit is determined based on the shapes of the three sub-pixels, and the overall shape of the pixel unit determines the arrangement of the pixel repeating arrangement units. Below, in several specific embodiments, the pixel repeating arrangement units and their arrangement methods are described in conjunction with several design shapes of the pixel unit and its included sub-pixels.

[0068] It should be noted that the first and second sub-pixels are located on opposite sides of the third sub-pixel; therefore, the first and second sub-pixels can be designed based on the shape of the third sub-pixel. Below, we will first describe several specific shapes of the third sub-pixel, and then explain several design methods for the first and second sub-pixels.

[0069] In at least one embodiment of the pixel unit provided in this disclosure, the planar shapes of the first sub-pixel, the second sub-pixel, and the third sub-pixel are all polygonal. The pixel edge of the third sub-pixel opposite to the first sub-pixel is a shared pixel edge of the third sub-pixel and the first sub-pixel; the pixel edge of the third sub-pixel opposite to the second sub-pixel is a shared pixel edge of the third sub-pixel and the second sub-pixel; and at least two opposite pixel edges of the third sub-pixel are not shared with any of the pixel edges of the first or second sub-pixel. Therefore, the number of pixel edges of the third sub-pixel is greater than the sum of the number of first and second sub-pixels, and the difference is not less than two, i.e., the third sub-pixel has at least six pixel edges. Thus, when arranging pixels based on pixel units, the unshared pixel edges of the third sub-pixel in a pixel unit can be joined with the unshared pixel edges of the third sub-pixel in adjacent pixel units, so that the pixel units are arranged relatively closely to improve the resolution of the displayed image.

[0070] In at least one embodiment of the pixel unit provided in this disclosure, such as Figure 5 As shown, the planar shape of the third sub-pixel 130 is hexagonal, while the planar shapes of the first sub-pixel 110 and the second sub-pixel 120 are both quadrilaterals. This hexagon includes a first pixel edge 131, a third pixel edge 133, a sixth pixel edge 136, a second pixel edge 132, a fourth pixel edge 134, and a fifth pixel edge 135, which are connected sequentially. Pixel edge 111 of the first sub-pixel 110 (corresponding to the first pixel edge 131 and the second pixel edge 132 of the third sub-pixel 130) is a shared pixel edge between the first sub-pixel 110 and the third sub-pixel 130. Pixel edge 121 of the second sub-pixel 120 (corresponding to the third pixel edge 133 and the fourth pixel edge 134 of the third sub-pixel 130) is a shared pixel edge between the second sub-pixel 120 and the third sub-pixel 130. The first pixel edge 131 and the second pixel edge 132 shared by the two first sub-pixels 110 of the third sub-pixel 130 are two opposite sides of a hexagon. Similarly, the third pixel edge 133 and the fourth pixel edge 134 shared by the two second sub-pixels 120 of the third sub-pixel 130 are two other opposite sides of a hexagon. The first pixel edge 131 and the third pixel edge 133 are connected, and the second pixel edge 132 and the fourth pixel edge 134 are connected. Thus, the third sub-pixel 130 is not opposite to the two pixel edges shared by the first sub-pixels 110 and the second sub-pixels 120.

[0071] For example, such as Figure 5As shown, the opposite sides of the hexagon are parallel to each other; that is, the first pixel side 131 and the second pixel side 132 are parallel to each other, the third pixel side 133 and the fourth pixel side 134 are parallel to each other, and the fifth pixel side 135 and the sixth pixel side 136 are parallel to each other. Furthermore, with the opposite sides having equal lengths, the hexagon is an axially symmetric and centrally symmetric figure, specifically formed by joining a rectangle and two isosceles triangles as described below.

[0072] In at least one embodiment of the pixel unit provided in this disclosure, such as Figure 5 As shown, the third sub-pixel 130 of the hexagon is formed by splicing a rectangle and two isosceles triangles. The two opposite sides of the rectangle share the base of the isosceles triangle; this base is a dummy side and will not be displayed after the graphics are spliced. The two sides of the rectangle not shared with the isosceles triangles, the first pixel side 131 and the second pixel side 132, are shared with the first sub-pixel 110. One side of each isosceles triangle (the third pixel side 133 or the fourth pixel side 134) also serves as a pixel side of the second sub-pixel 120. Thus, the third sub-pixel 130 of the hexagon is both centrally symmetric and axially symmetric, for example, having the following characteristics: Figure 5 The two axes of symmetry shown are L3 and L4. The axis of symmetry L3 passes through the centroid of the hexagon and the center of the first pixel side 131 and the second pixel side 132. The axis of symmetry L4 passes through the vertices of the two isosceles triangles mentioned above.

[0073] In the embodiments of this disclosure, there are no restrictions on the proportional relationships of the side lengths of the hexagon (which determine the size of its interior angles and the specific shape of the hexagon), and the design can be tailored to the needs of the actual process. For example, as Figure 5 As shown, the vertex angle of the isosceles triangle used to form the hexagon is a right angle. For example, further, the length of the two sides of the rectangle not shared with the isosceles triangle is half the length of the base of the isosceles triangle. Thus, the dimension of the third sub-pixel 130 along the axis of symmetry L3 is two-thirds of its dimension along the axis of symmetry L4.

[0074] In the following embodiment, the shape of the third sub-pixel is as follows: Figure 5 Taking the hexagon shown (axisymmetric and centrally symmetric) as an example, the shapes of the first and second sub-pixels will be explained.

[0075] For example, in some embodiments of this disclosure, such as... Figure 5As shown, the first sub-pixel 110 has a rectangular planar shape, comprising four sides 111-114, with sides 111 and 112 facing each other, and sides 113 and 114 facing each other. The second sub-pixel 120 has a right-angled trapezoidal planar shape, comprising a sloping side 121, a right-angled side 122, a top side 123, and a bottom side 124. Sides 113 and 123 coincide. The sloping side 121 serves as a shared pixel edge for the second sub-pixel 120 and the third sub-pixel 130, and side 111 serves as a shared pixel edge for the first sub-pixel 110 and the third sub-pixel 130.

[0076] based on Figures 2-5 The pixel unit 100 shown, a pixel repeating arrangement unit structure can be as follows: Figure 2 As shown, the pixel repeating unit 200 can be composed of two pixel units 100, which are arranged along the extension direction (row direction) of line L1 (or line L3). Furthermore, in each pixel repeating unit 200, the two pixel units intersect along the extension direction of line L4, which is perpendicular to line L3. That is, the two lines L3 defined by the centroids of the two first sub-pixels 110 in the two pixel units 100 are parallel to each other and spaced apart. For example, further, in each pixel repeating unit 200, the line defined by the centroids of the two first sub-pixels 110 in the pixel unit 100 passes through a second sub-pixel 120 in the other pixel unit 100. The degree of interlacing of the two pixel units 100 is the length of the pixel edge 112 of the first sub-pixel 110 that is away from the third sub-pixel 130. Thus, in the case where the first sub-pixel 110 is a square and the second sub-pixel 120 is a right-angled trapezoid mentioned in the foregoing embodiment, the ratio of the stagger distance between two pixel units 100 along the straight line L4 in the same pixel repeating unit 200 to the size of the entire pixel repeating unit 200 along the straight line L4 is 1 / 4. Thus, in each pixel repeating unit 200, in the region between two third sub-pixels 130, the pixel edge 112 of the first sub-pixel 110 of one pixel unit 100 facing away from the third sub-pixel 130 coincides with the right-angled side 122 (pixel edge) of the second sub-pixel 120 of another pixel unit 100. The pixel structure formed by the pixel repeating unit 200 based on the above design can be found in [reference needed]. Figure 3 and Figure 5 All pixel units 100 are connected to each other without gaps, so that the display area of ​​the display panel is used to arrange sub-pixels, thereby giving the display panel a larger resolution.

[0077] based on Figure 8 The pixel unit 100 shown can have a structure similar to another pixel repeating arrangement unit, as shown below. Figure 4As shown, a pixel repeating arrangement unit can consist of two pixel units, as in... Figure 8 The difference in the pixel repeating arrangement units shown is that, Figure 4 The degree of overlap between two pixel units in the pixel repeating arrangement shown is greater than the length of the pixel edge 112 of the first sub-pixel 110 that is away from the third sub-pixel 130. Thus, in each pixel repeating arrangement unit and in the region between two third sub-pixels 130, the right-angled edges (pixel edges) of the two second sub-pixels 120 of the two pixel units partially overlap. In the pixel structure formed by the pixel repeating arrangement units based on the above design, a dummy region 140 is formed between the four pixel units included in adjacent pixel repeating arrangement units in the same column; however, with... Figure 5 Compared to the situation shown, the degree of overlap between sub-pixels with the same preset light color is increased, which can further alleviate the problems of jagged edges and color fringing.

[0078] For some types of display panels, sub-pixels emitting different colors of light have varying light extraction efficiencies and lifespans. For example, for sub-pixels containing organic light-emitting devices (OLEDs), OLEDs with shorter wavelengths of emitted light have lower light extraction efficiency, requiring higher driving voltages and thus shorter lifespans. In the embodiments of this disclosure, by designing the area ratios of the three sub-pixels, the differences in light extraction efficiency and lifespan among these different types of sub-pixels can be compensated for. For example, in... Figure 5 In the illustrated embodiment, if the planar shape of the first sub-pixel 110 is designed as a square, the area ratio of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is 2:3:8. In each pixel unit 100, the area ratio of the two first sub-pixels 110, the two second sub-pixels 120, and the two third sub-pixels 130 is 2:3:4. This ratio can compensate for the differences in light emission efficiency, lifespan, etc., among the three sub-pixels, thereby ensuring the display effect of the displayed image while giving the product (e.g., the display panel described below) with this pixel unit a longer lifespan. It should be noted that the light emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel are respectively set as follows: Figure 5 In the case of green, red, and blue as shown, the above ratio of 2:3:4 can significantly improve the lifespan of the display panel.

[0079] In other embodiments of this disclosure, the pixel units can be based on Figure 9 The pixel unit 100 shown is modified to obtain, as Figure 9The pixel unit 100a shown is as follows: Specifically, the planar shape of the first sub-pixel 110a is still rectangular, the planar shape of the second sub-pixel 120a is changed to a parallelogram, and the pixel edge 123a shared with the first sub-pixel 110a and the pixel edge 121a shared with the third sub-pixel 130a of the second sub-pixel 120a are connected, the pixel edge 121a of the second sub-pixel 120a is parallel to the pixel edge 122a away from the third sub-pixel 130a, and the pixel edge 123a of the second sub-pixel 120a is parallel to the pixel edge 124a away from the first sub-pixel 110a.

[0080] based on Figure 10 The pixel unit 100a shown can be structured as follows: Figure 11 and Figure 10 As shown, a pixel unit 100a can serve as a pixel repeating arrangement unit 200a. The pixel repeating arrangement units 200a (pixel unit 100a) are arranged along the extension direction (row direction) of the straight line L1 (or the straight line L3), and the pixel repeating arrangement units 200a in the same row are connected and will not intersect along the straight line L4. Thus, the pixel edge of the first sub-pixel 110a of each pixel repeating unit 200a (or pixel unit 100a) that faces away from the third sub-pixel 130a coincides with the pixel edge of the first sub-pixel 110a of another pixel repeating unit 200a (or pixel unit 100a) in the same row that faces away from the third sub-pixel 130a. Similarly, the pixel edge of the second sub-pixel 120a of each pixel repeating unit 200a (or pixel unit 100a) that faces away from the third sub-pixel 130a coincides with the pixel edge of the second sub-pixel 120 of the adjacent pixel repeating unit 200a (or pixel unit 100a) in the same row that faces away from the third sub-pixel 130a. The pixel structure formed by the pixel repeating units 200 based on the above design can be found in [reference needed]. Figure 11 and Figure 9 All pixel repeating units 200a (or pixel units 100a) are connected to each other, and there can be no gaps between each pixel unit 100a, so that the display area of ​​the display panel is used to arrange sub-pixels, thereby enabling the display panel to have a larger resolution.

[0081] based on Figure 12 The pixel unit 100 shown can have a structure similar to another pixel repeating arrangement unit, as shown below. Figure 13 and Figure 10 As shown. (Similar to...) Figure 11 and Figure 10The difference in the pixel repeating arrangement unit shown is that the pixel repeating arrangement unit 200a can be composed of two pixel units 100a. The two pixel units 100a in each pixel repeating arrangement unit 200a are staggered along the extension direction of the line L4. That is, the line L3 defined by the centroids of the two first sub-pixels 110a in the two pixel units 100a is parallel to each other and spaced apart from each other. For example, further, in each pixel repeating arrangement unit 200a, the line defined by the centroids of the two first sub-pixels 110a in the pixel unit 100a passes through a second sub-pixel 120a in the other pixel unit 100a, and the degree of staggering is the length of the pixel edge of the first sub-pixel 110a away from the third sub-pixel 130a. Thus, when the first sub-pixel 110a is square, the ratio of the stagger distance of the two pixel units 100a in the same pixel repeating arrangement unit 200a along the line L4 to the size of the entire pixel repeating arrangement unit 200a along the line L4 is 1 / 4. In the pixel structure formed by the pixel repeating arrangement unit 200a based on the above design, a dummy region 140a is formed between the four pixel units included in adjacent pixel repeating arrangement units 200a in the same column. However, with Figure 11 and Figure 9 Compared to the situation shown, the degree of overlap between sub-pixels with the same preset light color is increased, which can further alleviate the problems of jagged edges and color fringing.

[0082] When the shape of the first sub-pixel is a square. Figure 9 In the pixel unit 100a shown, the area ratio of the first sub-pixel 110a, the second sub-pixel 120a, and the third sub-pixel 130a is 1:1:4. In each pixel unit 100a, the area ratio of the two first sub-pixels 110a, the two second sub-pixels 120a, and the two third sub-pixels 130a is 1:1:2. When the preset emission wavelength of the third sub-pixel 130a is relatively small (e.g., it emits blue light), this ratio can compensate for the deficiencies of the third sub-pixel 130a in terms of light emission efficiency and lifespan, so as to ensure the display effect of the displayed image while giving the product with this pixel unit (e.g., the display panel described below) a longer service life.

[0083] In some embodiments of the present disclosure, the pixel units can be based on Figure 16 The pixel unit 100a shown is modified to obtain, as Figure 17 and Figure 14 The pixel unit shown is 100b. The modification principle is as follows: Figure 15 and Figure 14As shown, the dummy region 140a is divided to compensate for the surrounding sub-pixels, thereby increasing the design area of ​​these sub-pixels and improving the aperture ratio. For example, as... Figure 15 and Figure 14 As shown, the dummy region 140a, surrounded by two first sub-pixels 110a and two second sub-pixels 120a, is a parallelogram. If the parallelogram is divided along its diagonals, four triangles (e.g., △BQC and △EQH) are obtained, defined by the intersection of the diagonals Q and the four sides. These four triangles are then merged with the adjacent first sub-pixel 110a or second sub-pixel 120a, thereby transforming the first sub-pixel 110a from parallelogram ABCD into trapezoid AQCD to obtain the first sub-pixel 110b, and the second sub-pixel 120a from rectangle EFGH into right trapezoid QEFGH to obtain the second sub-pixel 120b. The pixel edge shared by the first sub-pixel 110b and the third sub-pixel 130b is the right-angled side of the right trapezoid QEFGH. The pixel edge shared by the second sub-pixel 120b and the first sub-pixel 110b is the base edge of the right trapezoid QEFGH. Furthermore, the pixel edge of the second sub-pixel 120b that is opposite to the first sub-pixel 110b and the pixel edge shared with the first sub-pixel 110b are parallel.

[0084] For example, in embodiments of this disclosure, when the first sub-pixel is designed as a right-angled trapezoid and the second sub-pixel is designed as a trapezoid, the lengths of the top side and the right-angled legs of the right-angled trapezoid are equal; and / or, the ratio of the lengths of the top side and the bottom side of the right-angled trapezoid is 2 / 3, and the length of the pixel side shared by the second sub-pixel and the first sub-pixel is equal to the length of the top side of the right-angled trapezoid. Exemplarily, in cases such as... Figure 15 and Figure 16 In the transformation process shown, if the first sub-pixel 110b is a square, then in the obtained... Figure 17 and Figure 14 In the pixel unit 100b shown, the top edge HG and the right-angled waist GF of the first sub-pixel 110b of the right-angled trapezoid QEFGH are of equal length, the length ratio of the top edge HG to the bottom edge QF is 2 / 3, and the pixel edge DC shared by the second sub-pixel 120b with the first sub-pixel 110b is of equal length to the top edge HG of the right-angled trapezoid QEFGH.

[0085] based on Figure 15 and Figure 16 The pixel unit 100b obtained by the modification, and the structure of a pixel repeating arrangement unit 200b can be as follows: Figure 17 and Figure 12 As shown. The arrangement of pixel repeating arrangement units 200b is similar to that shown in the figure. Figure 13 and Figures 2-9The pixel repeating arrangement unit 200a shown has the same arrangement method, which will not be described in detail here. It should be noted that the pixel repeating arrangement units 200b are connected to each other, and there may be no gap between each pixel unit 100b, so that the display area of ​​the display panel is used to arrange sub-pixels, thereby enabling the display panel to have a larger resolution; in addition, the two pixel units 100b included in each pixel repeating arrangement unit 200b are arranged in an alternating manner along a direction perpendicular to the row direction (the extension direction of the straight line L4 mentioned in the previous embodiment) to alleviate the problems of jagged edges and color fringing.

[0086] In the embodiments of this disclosure, when a pixel repeating arrangement unit is composed of two pixel units, there are no restrictions on the positional relationships such as the spacing and stagger degree of the pixel units within the same pixel repeating arrangement unit, and other designs can be made according to actual needs. For example, in... Figures 12-17 and Figures 2-5 In all the pixel repeating units shown, the two first sub-pixels located between two third sub-pixels are centrally symmetrical, and the two second sub-pixels located between two third sub-pixels are also centrally symmetrical. Furthermore, in... Figures 12-13 , Figures 16-17 and ​ In all the pixel repeating units shown, the centers of symmetry of the two first sub-pixels and the centers of symmetry of the two second sub-pixels coincide.

[0087] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications or equivalent substitutions made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
