Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a pixel arrangement structure and a display panel. Background Technology

[0002] With the promising future of Augmented Reality (AR) / Virtual Reality (VR) headsets, the silicon-based OLED (OLED on silicon) industry is gradually accelerating its development. Silicon-based OLEDs will significantly improve the clarity, brightness, and size of AR / VR devices.

[0003] Silicon-based OLEDs are a technology developed to meet higher PPI requirements. Compared to traditional glass-based OLEDs, silicon-based OLEDs significantly increase PPI pixel density because the pixels are placed directly on a silicon wafer rather than a glass substrate, thus reducing the physical size of the display panel.

[0004] The pixel arrangement has a certain impact on the display effect of silicon-based OLEDs. In the traditional pixel arrangement structure, multiple strip-shaped sub-pixels of different colors are arranged alternately. This arrangement method can produce a grainy appearance on irregularly shaped display panels. For example, jagged edges are easily displayed on common rounded corners, c-corners, and other curved edges of display panels, resulting in a poor display effect. Summary of the Invention

[0010] Optionally, in the minimum repeating unit, the centers of all the third sub-pixels form a circle around the first sub-pixel and the second sub-pixel.

[0011] Optionally, the included angle between any two adjacent axes of symmetry in the first axis of symmetry, the second axis of symmetry, and the third axis of symmetry is the same.

[0012] Optionally, the first sub-pixel includes: a central portion and a plurality of protrusions respectively connected to the central portion; the protrusions include: a first protrusion, a second protrusion and a third protrusion; the extension direction of the first protrusion is opposite to the first direction; the extension direction of the second protrusion is opposite to the second direction; the extension direction of the third protrusion is opposite to the third direction; two adjacent protrusions and the central portion form a recessed area.

[0013] Optionally, the second sub-pixel includes at least a first sub-part; the first sub-part is disposed in the recessed region; and the shape of the first sub-part is the same as the shape of the recessed region.

[0014] Optionally, the minimum repeating unit includes a first sub-pixel, three second sub-pixels, and three third sub-pixels; the shape of the recessed region is trapezoidal; the shape of the second sub-pixel is trapezoidal; the shape of the third sub-pixel is strip-shaped; a second sub-pixel and a third sub-pixel are sequentially arranged along the first direction, the second direction, or the third direction; wherein the lower base of the trapezoid of the second sub-pixel is parallel to the long side of the strip of the third sub-pixel.

[0015] Optionally, the minimum repeating unit includes one first sub-pixel, three second sub-pixels, and six third sub-pixels; the shape of the recessed region is trapezoidal; the second sub-pixel is a hexagonal structure; the hexagonal structure is formed by splicing the first trapezoidal structure and the second trapezoidal structure; the first trapezoidal structure is disposed in the recessed region; the lower bases of the trapezoids of the first trapezoidal structure and the second trapezoidal structure coincide; the shape of the third sub-pixel is triangular; one second sub-pixel and two third sub-pixels are sequentially disposed along the first direction, the second direction, or the third direction; wherein, the two trapezoidal sidewalls of the second trapezoidal structure of the second sub-pixel are parallel to the edges of the triangles of the two third sub-pixels, respectively.

Within the plane formed by the pixel arrangement structure, starting from the center of the first sub-pixel, the second and third sub-pixels are sequentially arranged along a first direction, a second direction, and a third direction, respectively. Since each of these directions is different, the smallest repeating unit is centered on the first sub-pixel, with the second and third sub-pixels sequentially arranged along multiple directions.

Matrix-type units, including right angles, are prone to producing a grainy appearance on irregularly shaped screens. The graphic formed by the smallest repeating unit in this invention is smoother than a rectangle, thus reducing the jaggedness of the curved edges of the display panel and improving the display effect.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0034] like Figure 1 As shown, Figure 1This is a schematic diagram of a traditional pixel arrangement structure in the prior art. The pixel arrangement structure of a traditional display panel 11' generally includes sub-pixels 111' of various colors. Each color sub-pixel 111' is elongated, arranged in rows along the X-direction and columns along the Y-direction. Along the X-direction, the strip-shaped sub-pixels 111' of different colors are arranged alternately. Traditional pixel arrangement structures place high demands on the display algorithm of the display panel or display device. For example, to achieve the color ratio of different color sub-pixels 111', it is necessary to adjust the display brightness, number, and position of the different color sub-pixels 111', thus requiring extensive adjustments to the display algorithm of the entire display panel. Furthermore, the inventors have discovered that for irregularly shaped display panels containing R-corners, C-corners, curved edges, and recessed openings, such as… Figure 2 As shown, Figure 2 This is a partial structural diagram of an irregularly shaped screen with a traditional pixel arrangement in existing technology. It should be noted that... Figure 2 The diagonal line represents the edge of the display panel. Due to magnification, it appears as a straight line, but it is actually a curve or arc. The sub-pixels 111' of the aforementioned arc-shaped edge are all elongated, including right-angled structures. The presence of jagged edges between these right-angled structures and the arc-shaped edge during display can negatively impact the user's viewing experience.

[0035] To address the issue of graininess that easily appears at the edges of display panels, embodiments of the present invention provide a pixel arrangement structure, such as... Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of a pixel arrangement structure provided in an embodiment of the present invention. Figure 4 This is a schematic diagram of a minimum repeating unit provided in an embodiment of the present invention. The pixel arrangement structure 12 includes: a plurality of minimum repeating units 13; each minimum repeating unit 13 includes a first sub-pixel 131, at least three second sub-pixels 132 and at least three third sub-pixels 133; the first sub-pixel 131, the second sub-pixel 132 and the third sub-pixel 133 emit different colors;

[0036] In a plane parallel to the pixel arrangement structure 12, starting from the center O1 of the first sub-pixel 131, the second sub-pixel 132 and the third sub-pixel 133 are arranged sequentially along the first direction Z1; starting from the center O1 of the first sub-pixel 131, the second sub-pixel 132 and the third sub-pixel 133 are arranged sequentially along the second direction Z2; starting from the center O1 of the first sub-pixel 131, the second sub-pixel 132 and the third sub-pixel 133 are arranged sequentially along the third direction Z3; wherein the first direction Z1, the second direction Z2 and the third direction Z3 are all different.

[0037] In this embodiment of the invention, the minimum repeating unit includes a first sub-pixel, multiple second sub-pixels, and multiple third sub-pixels. Within the plane formed by the pixel arrangement structure, starting from the center of the first sub-pixel, the second and third sub-pixels are sequentially arranged along a first direction, a second direction, and a third direction, respectively. Since each of these directions is different, the minimum repeating unit is centered on the first sub-pixel, with the second and third sub-pixels sequentially arranged along multiple directions. This results in a sub-pixel group resembling a polygonal or circular arrangement, rather than the traditional matrix-type pixel unit. Matrix-type units, including right angles, are prone to producing a grainy appearance on irregularly shaped screens. In contrast, the graphic formed by the minimum repeating unit in this invention is smoother than a rectangle, thus reducing the jaggedness of the curved edges of the display panel and improving the display effect.

[0038] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] refer to Figure 3 and Figure 4 The pixel arrangement structure 12 includes multiple minimum repeating units 13, such as... Figure 3 As shown, multiple minimum repeating units 13 can be arranged closely. In this embodiment, the minimum repeating unit 13 includes a first sub-pixel 131, a second sub-pixel 132, and a third sub-pixel 133. The distinction between the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 is based on their different emission colors. Figure 4 As shown, each minimum repeating unit 13 includes a first sub-pixel 131, at least three second sub-pixels 132, and at least three third sub-pixels 133. Within the plane of the pixel arrangement structure, the present invention provides a first direction Z1, a second direction Z2, and a third direction Z3, and these directions are all different. It should be noted that these directions are unidirectional; that is, directions parallel to the first direction Z1 and opposite to it are not the first direction Z1. In this embodiment, starting from the center O1 of the first sub-pixel 131, the second sub-pixels 132 and third sub-pixels 133 are respectively arranged along the aforementioned directions. Specifically, in each direction, the second sub-pixels 132 and third sub-pixels 133 are sequentially positioned away from the first sub-pixel 131. Therefore, from the overall shape and arrangement of the minimum repeating unit 13, the minimum repeating unit 13 tends to form a sub-pixel group resembling a polygonal arrangement or a circular arrangement, such as... Figure 5 As shown, Figure 5This is a partial structural diagram of the pixel arrangement structure provided in an embodiment of the present invention at an irregular edge. The smallest repeating unit 13 at the curved edge, due to its relatively blunt overall shape, is less prone to graininess, thus improving the image display effect at the edge of the irregular screen. In contrast, traditional rectangular pixel units have sharper shapes, and when there is an angle between the edge of the display panel and the rectangle, the image is prone to jagged edges. Furthermore, the above... Figure 3 and Figure 4 Only one arrangement of the minimum repeating unit 13 is shown in this embodiment. This embodiment may also include other various forms, such as... Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of another minimal repeating unit provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of another minimal repeating unit provided in an embodiment of the present invention. Figure 3 The first sub-pixel 131 has a rotor-like structure. Figure 6 The first sub-pixel, 131, is a triangle. Figure 7 The first sub-pixel 131 is hexagonal. Furthermore, the shape of the second sub-pixel 132 can also be... Figure 4 The trapezoid shown can also be Figure 6 The rectangle shown has the following shape: the third sub-pixel 133 can be... Figure 4 The long strip shape in the middle can also be used for Figure 7 The multiple small rectangles shown in this embodiment do not impose any special limitations on the specific shapes of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133, nor do they impose any special limitations on the number of the second sub-pixel 132 and the third sub-pixel 133.

[0040] Optionally, in the pixel arrangement structure, the smallest repeating unit 13 is arranged sequentially along the first direction Z1, the second direction Z2, or the third direction Z3. (Continue to refer to...) Figure 3 The arrangement direction of the smallest repeating unit 13 is not the traditional row and column direction, but can be arranged along any one of the first direction Z1, the second direction Z2 or the third direction Z3. Alternatively, it can be arranged along two or three of the first direction Z1, the second direction Z2 and the third direction Z3 to form a tightly arranged pixel arrangement structure and improve the display detail.

[0041] Continue to refer to Figures 4 to 7Optionally, the first sub-pixel 131 includes a first axis of symmetry L1 along a first direction Z1, a second axis of symmetry L2 along a second direction Z2, and a third axis of symmetry L3 along a third direction Z3; the second sub-pixel 132 and the third sub-pixel 133 arranged sequentially along the first direction Z1 are both symmetrically arranged about the first axis of symmetry L1; the second sub-pixel 132 and the third sub-pixel 133 arranged sequentially along the second direction Z2 are both symmetrically arranged about the second axis of symmetry L2; the second sub-pixel 132 and the third sub-pixel 133 arranged sequentially along the third direction Z3 are both symmetrically arranged about the third axis of symmetry L3.

[0042] The first axis of symmetry, L1, extends along the first direction, Z1. It's important to note that the first axis of symmetry, L1, has no direction of its own; it is a straight line. Similarly, the second axis of symmetry, L2, extends along the second direction, Z2, and the third axis of symmetry, L3, extends along the third direction, Z3. Figure 4 As shown, the first sub-pixel 131 includes multiple axes of symmetry in different directions. Specifically, the first sub-pixel 131 includes a first axis of symmetry L1, a second axis of symmetry L2, and a third axis of symmetry L3. Thus, the first sub-pixel 131 has a shape that is symmetrical in multiple directions, which facilitates the arrangement of sub-pixels from the first direction Z1, the second direction Z2, and the third direction Z3, enhances the regularity of the arrangement, and the symmetrical first sub-pixel 131 is conducive to achieving uniformity of display in different display areas of the display panel.

[0043] Figure 8 This is a schematic diagram of another minimum repeating unit provided in an embodiment of the present invention. Optionally, in the minimum repeating unit 13, the centers of all the third sub-pixels 133 form a circle around the first sub-pixel 131 and the second sub-pixel 132. This further enhances the symmetry of the minimum repeating unit 13 and makes the shape of the entire minimum repeating unit 13 approach a circle, greatly enhancing the smoothness of the minimum repeating unit 13, reducing the jaggedness of the edges of irregularly shaped screens, and improving the image display effect.

[0044] Figure 9 This is a schematic diagram of another minimal repeating unit provided in an embodiment of the present invention. Figure 10 This is a schematic diagram of another minimal repeating unit provided in an embodiment of the present invention. Similarly, Figure 9 and Figure 10 The first sub-pixel 131 includes a first axis of symmetry L1 along a first direction Z1, a second axis of symmetry L2 along a second direction Z2, and a third axis of symmetry L3 along a third direction Z3, and the centers of all the third sub-pixels 133 form a circle around the first sub-pixel 131 and the second sub-pixel 132. (Reference) Figure 5 and Figure 7In this embodiment of the invention, the pixel arrangement is a non-traditional rectangular pattern. The R / G / B pixels are arranged in a circle and are symmetrically distributed in the center, which is beneficial for curved display (such as rounded corners, hole areas and other irregular areas), thereby effectively reducing the jaggedness of the display, reducing the graininess of the display, and improving the fineness of the image. Figure 11 This is a schematic diagram of another pixel arrangement structure provided in an embodiment of the present invention, which shows that... Figure 9 The smallest repeating unit 13 shown can also be arranged sequentially along the first direction Z1, the second direction Z2 and / or the third direction Z3 to form a compact structure, thereby increasing the screen resolution.

[0045] Continue to refer to Figures 4 to 11 Optionally, the included angles between adjacent pairs of the first axis of symmetry L1, the second axis of symmetry L2, and the third axis of symmetry L3 are the same. The identical included angles between these three axes of symmetry further enhance the symmetry of the minimum repeating unit 13, making its shape closer to a regular hexagon or circle, further reducing the jaggedness of the irregular areas of the screen and improving the display effect.

[0046] Continue to refer to Figure 4 Optionally, the first sub-pixel 131 includes: a central portion 137 and a plurality of protrusions respectively connected to the central portion 137; the protrusions include: a first protrusion 134, a second protrusion 135 and a third protrusion 136; the extension direction of the first protrusion 134 is opposite to the first direction Z1; the extension direction of the second protrusion 135 is opposite to the second direction Z2; the extension direction of the third protrusion 136 is opposite to the third direction Z3; two adjacent protrusions and the central portion 137 form a recessed region A1.

[0047] like Figure 4 As shown, in this embodiment, the first sub-pixel 131 can form a rotor-like structure. Specifically, the first sub-pixel 131 may include a first protrusion 134, a second protrusion 135, a third protrusion 136, and a central portion 137 connecting each protrusion. The extension direction of the first protrusion 134 is parallel to and opposite to the first direction Z1. Similarly, the extension direction of the second protrusion 135 is parallel to and opposite to the second direction Z2. The extension direction of the third protrusion 136 is parallel to and opposite to the third direction Z3. Furthermore, to further enhance the compactness of the entire minimum repeating unit 13, adjacent protrusions and the central portion 137 can form a recessed region A1. The two closest sides of the two adjacent protrusions and the edge of the central portion 137 delineate the shape of the recessed region A1. The recessed region A1 allows the second sub-pixel 132 to occupy at least a portion of the space in the recessed region A1, thereby saving the overall space occupied by the minimum repeating unit 13 and improving pixel resolution.

[0048] Continue to refer to Figure 4Optionally, the second sub-pixel 132 includes at least a first sub-part 132a; the first sub-part 132a is disposed in the recessed region A1; and the shape of the first sub-part 132a is the same as the shape of the recessed region A1. In this embodiment, the specific shape of the first sub-part 132a can be set to be the same as the shape of the recessed region A1, so that the first sub-part exactly occupies the space of the recessed region A1, further increasing the setting density of sub-pixels. For the same area of ​​the second sub-pixel 132, the overall space occupied by the minimum repeating unit 13 can be saved, and the pixel resolution can be improved.

[0049] Continue to refer to Figure 4 Optionally, the minimum repeating unit 13 includes a first sub-pixel 131, three second sub-pixels 132, and three third sub-pixels 133; the concave region A1 is trapezoidal in shape; the second sub-pixel 132 is trapezoidal in shape; the third sub-pixel 133 is strip-shaped; a second sub-pixel 132 and a third sub-pixel 133 are sequentially arranged along the first direction Z1, the second direction Z2, or the third direction Z3; wherein, the lower base of the trapezoid of the second sub-pixel 132 is parallel to the long side of the strip of the third sub-pixel 133.

[0050] In this embodiment, the first sub-pixel 131 can be selected to have a rotor-like structure shape, so the shape of the recessed area A1 is trapezoidal. Correspondingly, the shape of the second sub-pixel 132 is trapezoidal, and the shape of the third sub-pixel 133 is elongated. This embodiment includes three second sub-pixels 132 and three third sub-pixels 133. In the first direction Z1, the second direction Z2, and the third direction Z3, one second sub-pixel 132 and one third sub-pixel 133 can be sequentially set. The second sub-pixel 132 is placed within the recessed area A1, effectively saving the layout space of the minimum repeating unit 13. Furthermore, a trapezoid generally includes an upper base, a side waist, and a lower base. The lower base of the second sub-pixel 132 and the long side of the third sub-pixel 133 can be set parallel to each other. Figure 4 As shown, the entire smallest repeating unit 13 forms a hexagonal structure, which has a certain buffer between it and the irregular edge, effectively avoiding the jaggedness of the screen display and improving the display effect.

[0051] Continue to refer to Figure 9Optionally, the minimum repeating unit 13 includes a first sub-pixel 131, three second sub-pixels 132, and six third sub-pixels 133; the concave region A1 is trapezoidal in shape; the second sub-pixel 132 is a hexagonal structure; the hexagonal structure is formed by splicing a first trapezoidal structure T1 and a second trapezoidal structure T2; the first trapezoidal structure T1 is disposed in the concave region A1; the lower bases of the trapezoids of the first trapezoidal structure T1 and the second trapezoidal structure T2 coincide; the third sub-pixel 133 is triangular in shape; along the first direction Z1, the second direction Z2, or the third direction Z3, one second sub-pixel 132 and two third sub-pixels 133 are sequentially disposed; wherein, the two trapezoidal side waists of the second trapezoidal structure T2 of the second sub-pixel 132 are parallel to the triangular edges of the two third sub-pixels 133 respectively.

[0052] Similarly, in this embodiment, the first sub-pixel 131 can be selected to have a rotor-like structure shape, then the shape of the recessed region A1 is trapezoidal. Correspondingly, the second sub-pixel 132 is a hexagonal structure, which includes a first trapezoidal structure T1 and a second trapezoidal structure T2. The first trapezoidal structure T1 can serve as the first sub-part 132a, which is disposed in the recessed region A1, thus reducing the overall area occupied by the minimum repeating unit 13. The lower bases of the first trapezoidal structure T1 and the second trapezoidal structure T2 coincide. Furthermore, the third sub-pixel 133 is triangular in shape. It should be noted that in this embodiment, the minimum repeating unit 13 includes one first sub-pixel 131, three second sub-pixels 132, and six third sub-pixels 133. In the first direction Z1, the second direction Z2, and the third direction Z3, each direction is sequentially provided with one second sub-pixel 132 and two third sub-pixels 133. In this embodiment, the second trapezoidal structure T2 of the second sub-pixel 132 includes side waist S1 and side waist S2. Side waist S1 is parallel to a certain triangle edge of one of the two third sub-pixels 133, and side waist S2 is parallel to a certain triangle edge of the other of the two third sub-pixels 133. This further increases the occupied space of the minimum repeating unit 13 and makes the final shape of the minimum repeating unit 13 closer to a hexagon, improving the bluntness of the overall shape of the minimum repeating unit 13, avoiding sharp right angles or irregular shapes in the minimum repeating unit 13, and improving the display effect of irregular areas.

[0053] Continue to refer to Figures 4 to 11 Optionally, the first sub-pixel 131 is a blue sub-pixel; the second sub-pixel 132 is a red sub-pixel; and the third sub-pixel 133 is a green sub-pixel; or, the second sub-pixel 132 is a green sub-pixel; and the third sub-pixel 133 is a red sub-pixel. In the smallest repeating unit 13, the area of ​​the first sub-pixel 131 is greater than the total area of ​​the second sub-pixel 132; and the area of ​​the first sub-pixel 131 is greater than the total area of ​​the third sub-pixel 133.

[0054] In this embodiment, the first sub-pixel 131 is set as a blue sub-pixel, and the area of ​​the first sub-pixel 131 is larger than the area of ​​other color sub-pixels. This effectively increases the light-emitting area of ​​the blue sub-pixel, effectively avoids color shift caused by the lifespan decay of the blue sub-pixel, and improves the display lifespan of the pixel arrangement structure and even the entire display panel.

[0055] Based on the above embodiments, Figure 12 This is a schematic diagram of a conventional pixel arrangement provided in an embodiment of the present invention. Figure 13 This is a schematic diagram of a pixel arrangement structure provided in an embodiment of the present invention. It can be seen that the area in both diagrams is the same, and the pitch (distance between sub-pixels) is 50. Under the same luminous area and size, simple calculations show that the luminous area of ​​the red sub-pixel R, green sub-pixel G, and blue sub-pixel B in a traditional pixel arrangement is 60258.3547. In this embodiment, the areas of the first sub-pixel B, the second sub-pixel R, and the third sub-pixel G are 91380.5284, 50939.3234, and 68257.2042, respectively. Comparison reveals that the area of ​​the blue sub-pixel is 1 / 3 larger than that of the blue sub-pixel in the traditional pixel arrangement. Because the blue sub-pixel area is larger, it reduces color shift caused by lifespan decay. In this pixel arrangement structure, only the red sub-pixel has a smaller area than the traditional pixel arrangement; the areas of other color sub-pixels are larger, effectively solving the problem of low luminous efficiency of the blue sub-pixel affecting the lifespan of the display panel.

[0056] Furthermore, because each minimum repeating unit 13 includes multiple second sub-pixels and multiple third sub-pixels, pixel borrowing can be used to further improve the PPI resolution of the display panel during image display, and the process feasibility is high. Therefore, the pixel arrangement structure in this embodiment is more suitable for silicon-based OLED microdisplays, which can achieve... Figures 4 to 11 The use of tiny, multi-shaped sub-pixels effectively improves pixel resolution. The panel size is approximately 1 inch, and the substrate is a single-crystal silicon substrate, not a glass substrate. The substrate driving circuit is fabricated using CMOS technology, and the pixel arrangement can be fabricated using an exposure method to create the colored adhesive for red sub-pixels R, green sub-pixels G, and blue sub-pixels B. Furthermore, the pixel arrangement of red sub-pixels R, green sub-pixels G, and blue sub-pixels B in this embodiment is beneficial for the display effect of dots and lines.
