Description

Technical Field

[0001] This invention belongs to the field of display technology, specifically relating to a display substrate and a display device. Background Technology

[0002] Organic light-emitting diode (OLED) display devices are one of the hottest research topics in the field of flat panel displays today. Compared with liquid crystal displays, OLED display devices have advantages such as low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. At present, in the field of flat panel displays such as mobile phones, tablets, and digital cameras, OLED display devices have begun to replace traditional liquid crystal displays (LCDs).

[0003] The structure of an OLED display device mainly includes: a substrate, and pixels arranged in a matrix on the substrate. Each pixel is typically formed by depositing organic materials using a vapor deposition technique through a high-precision metal mask, creating an organic electroluminescent device at its corresponding pixel position on the array substrate.

[0004] However, in current OLED display devices, the pixel spacing in the pixel arrangement is relatively large, resulting in a smaller pixel aperture area under the same resolution conditions. This necessitates increasing the driving current to meet the display brightness requirements. However, operating OLEDs under high driving currents can accelerate device aging, thereby shortening the lifespan of the OLED display device. Summary of the Invention

[0071] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0073] It should be noted that the row direction and column direction involved in the embodiments of this disclosure represent only two different directions, and they are not limited to being perpendicular to each other. The accompanying drawings of the embodiments of this disclosure are only used as an example of the row direction and column direction being perpendicular, but this does not constitute a limitation on the embodiments of this disclosure.

[0074] Furthermore, the descriptions of "same" and "equal" used in the embodiments of this disclosure do not mean that two objects are completely equal in size or have the same shape. They are allowed to be approximately the same or approximately equal within a certain error range.

[0075] Before describing the pixel array, display device, and high-precision mask according to embodiments of this disclosure, the concepts of sub-pixel, first sub-pixel, second sub-pixel, and third sub-pixel mentioned in the following description will be explained. In embodiments of this disclosure, a pixel array refers to the arrangement structure of light-emitting devices of different colors in a display substrate, and is not limited to the arrangement structure of pixel circuits used to drive each light-emitting device. Accordingly, it should be understood that in embodiments of this disclosure, a sub-pixel refers to the structure of the light-emitting device, and the first sub-pixel, second sub-pixel, and third sub-pixel represent three different colored sub-pixels. In this embodiment, the first sub-pixel is described as a red sub-pixel, the second sub-pixel as a green sub-pixel, and the third sub-pixel as a blue sub-pixel. However, the fact that the first sub-pixel is red, the second sub-pixel is green, and the third sub-pixel is blue does not constitute a limitation on the scope of protection of embodiments of this disclosure.

[0076] Typically, the shape of each sub-pixel is determined by the pixel opening in the pixel defining layer. Since the light-emitting layer is at least partially formed within the pixel opening, it defines the shape of the light-emitting area of ​​that sub-pixel, which is the shape of the sub-pixel referred to in the embodiments of this disclosure. When the pixel opening is quadrilateral, the sub-pixel is quadrilateral.

[0077] Furthermore, in this embodiment of the disclosure, at least one of the red, green, and blue sub-pixels is described as having a polygonal shape. This embodiment will be illustrated using the example where all three sub-pixels are polygons. A polygon can have three or more corners depending on its shape; for example, a quadrilateral or similar shape includes four vertices. Figure 3a This is a schematic diagram of a polygon; Figure 3b A schematic diagram of another type of polygon; such as Figure 3a and 3b As shown, each polygon includes four vertices, namely the first corner, the second corner, the third corner, and the fourth corner; wherein the first and second corners are arranged opposite each other, and the third and fourth corners are arranged opposite each other, for example. Of course, it should be understood that if a sub-pixel is a polygon, it can have more vertices, and this is not limited in this embodiment. However, it should be noted that the so-called vertices in this embodiment are not necessarily the angle between two lines; in fact, they can also be the intersection of the two sides of a vertex extending towards its vertex, forming an arc segment or a straight line segment, so that the vertex is a rounded or flat chamfer. For example... Figure 3a As shown in the embodiments of this disclosure, the first corner 11 of at least one of the blue, red, and green sub-pixels is rounded or flat-edged, while the other corners are similar to right angles. However, this does not constitute a limitation on the embodiments of this disclosure. The second, third, and fourth corners are substantially the same, for example, similar to right angles; that is, these three corners can be rounded, but the radius of curvature of the corresponding rounded corners is relatively small, smaller than the radius of curvature of the first corner. It should be noted that "substantially the second, third, and fourth corners are substantially the same" means, for example, that these three have the same angle, the same outline, the same size, and the same curvature of the rounded corners.

[0078] To clarify the structure of each sub-pixel in the pixel array of this disclosure embodiment, the film structure of the pixel array of this disclosure embodiment will be described below in conjunction with the pixel array fabrication method. Figure 1 This is a schematic diagram of an exemplary pixel array film structure; as shown. Figure 1 As shown,

[0079] This method may specifically include the following steps:

[0080] (1) Prepare a substrate on a glass carrier.

[0081] In some exemplary embodiments, the substrate 10 can be a flexible substrate, such as including a first flexible material layer, a first inorganic material layer, a semiconductor layer, a second flexible material layer, and a second inorganic material layer stacked on a glass substrate. The first and second flexible material layers are made of materials such as polyimide (PI), polyethylene terephthalate (PET), or surface-treated polymer films. The first and second inorganic material layers are made of materials such as silicon nitride (SiNx) or silicon oxide (SiOx) to improve the substrate's resistance to water and oxygen; these first and second inorganic material layers are also referred to as barrier layers. The semiconductor layer is made of amorphous silicon (a-Si). In some exemplary embodiments, taking the stacked structure PI1 / Barrier1 / a-si / PI2 / Barrier2 as an example, its fabrication process includes: firstly, coating a layer of polyimide on a glass substrate 1, curing it to form a first flexible (PI1) layer; then depositing a barrier film on the first flexible layer to form a first barrier (Barrier1) layer covering the first flexible layer; then depositing an amorphous silicon film on the first barrier layer to form an amorphous silicon (a-si) layer covering the first barrier layer; then coating another layer of polyimide on the amorphous silicon layer, curing it to form a second flexible (PI2) layer; then depositing a barrier film on the second flexible layer to form a second barrier (Barrier2) layer covering the second flexible layer, thus completing the fabrication of the substrate 10. Figure 6 As shown.

[0082] (2) Fabricate a driving structure layer on the substrate. The driving structure layer includes multiple driving circuits, each driving circuit including multiple transistors and at least one storage capacitor, such as a 2T1C, 3T1C, or 7T1C design. An example of three sub-pixels is used for illustration, and the driving circuit for each sub-pixel is illustrated using only one transistor and one storage capacitor.

[0083] In some embodiments, the fabrication process of the driving structure layer can be described with reference to the following description. The fabrication process of the driving circuit of the red sub-pixel 01 is used as an example for illustration.

[0084] A first insulating film and an active layer film are sequentially deposited on the substrate 10. The active layer film is patterned by a patterning process to form a first insulating layer 011 covering the entire substrate 010, and an active layer pattern disposed on the first insulating layer 011.

The second gate metal layer pattern includes at least a second capacitor electrode, and the position of the second capacitor electrode corresponds to the position of the first capacitor electrode.

[0087] Subsequently, a fourth insulating film is deposited, and the fourth insulating film is patterned by a patterning process to form a pattern of the fourth insulating layer 014 covering the second gate metal layer. At least two first vias are formed on the fourth insulating layer 014. The fourth insulating layer 014, the third insulating layer 013 and the second insulating layer 012 in the two first vias are etched away to expose the surface of the first active layer.

[0088] Subsequently, a third metal thin film is deposited, and the third metal thin film is patterned using a patterning process to form a source / drain metal layer pattern on the fourth insulating layer 014. The source / drain metal layer includes at least a first source electrode and a first drain electrode located in the display area.

The active layer thin film uses one or more materials such as amorphous indium gallium zinc oxide (a-IGZO), zinc oxynitride (ZnON), indium zinc tin oxide (IZTO), amorphous silicon (a-Si), polycrystalline silicon (p-Si), hexathiophene, and polythiophene. That is, this disclosure is applicable to transistors manufactured based on oxide technology, silicon technology, and organic technology.

[0094] In some exemplary embodiments, a conductive thin film is deposited on the substrate 010 on which the aforementioned pattern is formed, and the conductive thin film is patterned by a patterning process to form a first electrode pattern. The first anode 213 of the red sub-pixel 01 is connected to the first drain electrode of the first transistor 210 through a second via, the second anode 223 of the green sub-pixel 022 is connected to the first drain electrode of the first transistor of the green sub-pixel 02 through a second via, and the third anode 233 of the blue sub-pixel 23 is connected to the first drain electrode of the first transistor of the blue sub-pixel 03 through a second via.

[0095] In some examples, the first electrode can be made of a metallic material, such as any one or more of magnesium (Mg), silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), and molybdenum (Mo), or an alloy of the above metals, such as aluminum-neodymium alloy (AlNd) or molybdenum-niobium alloy (MoNb). It can be a single-layer structure or a multi-layer composite structure, such as Ti / Al / Ti, or a stacked structure formed of metal and transparent conductive material, such as reflective materials like ITO / Ag / ITO or Mo / AlNd / ITO.

[0097] In some exemplary embodiments, a pixel definition film is coated on the substrate 010 on which the aforementioned pattern is formed, and the pixel definition layer pattern is formed by masking, exposure, and development processes. For example... Figure 12 As shown, the pixel definition layer 30 of the display area includes a plurality of sub-pixel definition portions 302, and a plurality of pixel definition layer openings 301 are formed between adjacent sub-pixel definition portions 302.

[0100] In some exemplary embodiments, an organic material thin film is coated on the substrate 010 on which the aforementioned pattern is formed, and the spacer pillar 34 pattern is formed by a masking, exposure, and development process. The spacer pillar 34 can serve as a support layer, configured to support the FMM during the evaporation process. In some examples, along the row arrangement direction of the subpixels, a repeating unit is spaced between two adjacent spacer pillars 34; for example, the spacer pillar 34 can be located between adjacent red subpixel 01 and blue subpixel 03.

[0101] (7) An organic functional layer and a second electrode are sequentially formed on the substrate on which the aforementioned pattern is formed. In some examples, the second electrode is a transparent cathode. The light-emitting element can emit light from the side away from the substrate 010 through the transparent cathode, achieving top emission. In some examples, the organic functional layer of the light-emitting element includes: a hole injection layer, a hole transport layer, a light-emitting layer, and an electron transport layer.

[0102] In some exemplary embodiments, a hole injection layer 241 and a hole transport layer 242 are sequentially deposited on the substrate 010 on which the aforementioned pattern is formed using an open mask. Then, a blue light-emitting layer 236, a green light-emitting layer 216, and a red light-emitting layer 226 are sequentially deposited using an open mask. Finally, an electron transport layer 243, a cathode 244, and an optical coupling layer 245 are sequentially deposited using an open mask. The hole injection layer 241, hole transport layer 242, electron transport layer 243, and cathode 244 are all common layers for multiple sub-pixels. In some examples, the organic functional layer may further include a microcavity adjustment layer located between the hole transport layer and the light-emitting layer. For example, after forming the hole transport layer, a blue microcavity adjustment layer, a blue light-emitting layer, a green microcavity adjustment layer, a green light-emitting layer, a red microcavity adjustment layer, and a red light-emitting layer may be sequentially deposited using an FMM.

[0103] In some exemplary embodiments, an organic functional layer is formed within a sub-pixel region, enabling the organic functional layer to be connected to the anode. A cathode is formed on the pixel definition layer and connected to the organic functional layer.

[0104] In some exemplary embodiments, the cathode may be any one or more of magnesium (Mg), silver (Ag), and aluminum (Al), or an alloy made of any one or more of the above metals, or a transparent conductive material, such as indium tin oxide (ITO), or a multilayer composite structure of metal and transparent conductive material.

[0105] In some exemplary embodiments, an optical coupling layer can be formed on the side of the cathode 244 away from the substrate 10. This optical coupling layer can be a common layer for multiple sub-pixels. The optical coupling layer can work in conjunction with the transparent cathode to increase light output. For example, the material of the optical coupling layer can be a semiconductor material. However, this embodiment is not limited to this.

[0106] (8) An encapsulation layer is formed on the substrate on which the aforementioned pattern is formed.

[0107] In some exemplary embodiments, an encapsulation layer is formed on the substrate 010 on which the aforementioned pattern is formed. The encapsulation layer may include a first encapsulation layer 41, a second encapsulation layer 42, and a third encapsulation layer 43 stacked together. The first encapsulation layer 41 is made of an inorganic material and covers the cathode 244 in the display area. The second encapsulation layer 42 is made of an organic material. The third encapsulation layer 43 is made of an inorganic material and covers the first encapsulation layer 41 and the second encapsulation layer 42. However, this embodiment is not limited to this. In some examples, the encapsulation layer may adopt a five-layer structure of inorganic / organic / inorganic / organic / inorganic.

[0108] Figure 2 A schematic diagram illustrating an exemplary pixel array is shown, such as Figure 2As shown, the pixel array includes multiple rows of first pixel rows 1 and multiple rows of second pixel rows 2, with the first pixel rows 1 and second pixel rows 2 alternating. The first pixel row 1 is formed by alternating red sub-pixels 01 and blue sub-pixels 03, and the red sub-pixels 01 and blue sub-pixels 03 in the same column of the multiple rows of first pixel rows 1 are also alternating. The second pixel row 2 is formed by multiple green sub-pixels 02 arranged side-by-side, with the green sub-pixels 02 interleaved with the red sub-pixels 01 and blue sub-pixels 03 in adjacent rows. For this pixel arrangement, the pixel array can be divided into repeating units arranged in an array. Each repeating unit includes two rows and four columns of sub-pixels, that is, each repeating unit includes one red sub-pixel 01, one blue sub-pixel 03, and two green sub-pixels 02. The red sub-pixels 01 and blue sub-pixels 03 are shared sub-pixels. Through a virtual algorithm, four sub-pixels can achieve the display of two virtual pixel units. For example, the red sub-pixel 01 in the second repeating unit of the first row, together with the blue sub-pixel 03 in the first repeating unit of the first row and the nearest green sub-pixel 02, forms a virtual pixel unit. At the same time, the red sub-pixel 01 in the second repeating unit of the first row, together with the blue sub-pixel 03 in the same repeating unit and the nearest green sub-pixel 02, also forms a virtual pixel unit. In addition, the blue sub-pixel 03 in the second repeating unit of the first row, together with another green sub-pixel 02 in the same repeating unit and the nearest red sub-pixel 01 in the third repeating unit of the first row, forms a virtual pixel unit. This can effectively improve the resolution of the display panel using this pixel array.

[0109] However, the inventors discovered that since the red sub-pixel 01 and the blue sub-pixel 03 are shared sub-pixels and, according to their emission spectra, the areas of both are larger than the area of ​​the green sub-pixel 02, especially the area of ​​the blue sub-pixel 03, which is larger than that of the red sub-pixel 01, the actual brightness center formed by each virtual pixel unit is not uniform when the display panel is displayed. The following technical solution is provided in the embodiments of this disclosure.

[0110] Firstly, Figure 4 This is a schematic diagram of a pixel array (first example) according to an embodiment of this disclosure. Figure 4As shown, this embodiment of the present disclosure provides a pixel array comprising multiple rows of first pixel rows 1 and multiple rows of second pixel rows 2, wherein the first pixel rows 1 and the second pixel rows 2 are alternately arranged. The first pixel rows 1 are formed by alternating arrangements of red sub-pixels 01 and blue sub-pixels 03, and the red sub-pixels 01 and blue sub-pixels 03 located in the same column within the multiple rows of first pixel rows 1 are also alternately arranged. The second pixel rows 2 are formed by multiple green sub-pixels 02 arranged side-by-side, and the green sub-pixels 02 are staggered with the red sub-pixels 01 and blue sub-pixels 03 in adjacent rows. The centers of two red sub-pixels 01 and two blue sub-pixels 03 arranged in an array are connected sequentially to form a first virtual quadrilateral 10, and a green sub-pixel 02 is set in each first virtual quadrilateral 10; wherein at least some of the interior angles of the first virtual quadrilateral 10 are not equal to 90°; the shapes of the red sub-pixels 01, green sub-pixels 02 and blue sub-pixels 03 are all polygons, and the distance from the intersection of the extensions of the two sides of at least one vertex of at least one of these three polygonal sub-pixels to the center of the sub-pixel is not equal to the distance from the intersection of the extensions of the two sides of the opposite diagonal of the sub-pixel to the center of the sub-pixel.

[0111] It should be noted that, in the embodiments of this disclosure, the polygons include, but are not limited to, rounded polygons, convex polygons, and concave polygons. The center of a sub-pixel is, for example, the geometric center of the sub-pixel, or the intersection of the perpendicular bisectors of the sides of the sub-pixel, or a point in the sub-pixel whose perpendicular distance to each side is approximately equal. Of course, the center of the sub-pixel can have a certain degree of error. For example, the center of a sub-pixel can be any point within a radius of 3 μm centered on the geometric center of the sub-pixel.

[0112] In this embodiment of the disclosure, by adjusting the shape of some sub-pixels, at least some interior angles of the first virtual quadrilateral 10 formed by the center line connecting the centers of red sub-pixel 01 and blue sub-pixel 03 are not equal to 90°, and the distance from the intersection of the extension lines of at least one of the two sides of at least one vertex of red sub-pixel 01, green sub-pixel 02, and blue sub-pixel 03 to the center of the sub-pixel is not equal to the distance from the intersection of the extension lines of the two sides of its opposite corner to the center of the sub-pixel, so as to adjust the actual brightness center in each virtual pixel unit, making the distribution of each actual brightness center in the entire display panel more uniform.

[0113] In some embodiments, if the first corner of blue sub-pixel 03 is a rounded chamfer or a flat chamfer, the distance from the vertex of the first corner of blue sub-pixel 03 to the boundary of the light-emitting layer is not equal to the distance from the vertices of other vertices to the boundary of the light-emitting layer. For example, the vertex of the first corner of blue sub-pixel 03 has a certain distance to the boundary, while the distance from other vertices to the boundary of the pixel is approximately 0. That is, the distance from the vertex of the first corner of blue sub-pixel 03 to the boundary is greater than the distance from the vertices of other vertices to the boundary of blue sub-pixel 03.

[0114] Continue to refer to Figure 4The light-emitting layer located in the pixel defining layer defines the effective light-emitting area of ​​the sub-pixel. The effective light-emitting areas of red sub-pixel 01, green sub-pixel 02, and blue sub-pixel 03 are respectively the first effective light-emitting area, the second effective light-emitting area, and the third effective light-emitting area. In some embodiments, each first effective light-emitting area is defined by a light-emitting layer in the corresponding red sub-pixel 01, located between opposing anodes and cathodes in the direction perpendicular to the substrate, and driven to emit light. For example, each second effective light-emitting area is defined by a light-emitting layer in the corresponding green sub-pixel 02, located between opposing anodes and cathodes in the direction perpendicular to the substrate, and driven to emit light. In some embodiments, each effective light-emitting area is defined by a corresponding light-emitting layer and an electrode (anode or cathode) or a portion of an electrode that carries charge carriers (holes or electrons) with the corresponding light-emitting layer. In some embodiments, each effective light-emitting area is defined by at least a portion of a cathode and at least a portion of an anode whose orthogonal projections on the substrate overlap, and the at least portion of the cathode and at least a portion of the anode do not overlap with the orthogonal projection of a first insulating layer on the substrate, which is located between the cathode and the anode in the direction perpendicular to the substrate. For example, the first insulating layer includes a pixel defining layer. In some embodiments, each red sub-pixel 01, each green sub-pixel 02, and each blue pixel 03 respectively includes a first electrode, a light-emitting layer located on the side of the first electrode away from the substrate, and a second electrode located on the side of the light-emitting layer away from the first electrode. In the direction perpendicular to the substrate, a second insulating layer is further disposed between the first electrode and the light-emitting layer, and / or between the second electrode and the light-emitting layer. The second insulating layer overlaps with the first electrode or the second electrode projected onto the substrate, and the second insulating layer has an opening. On the side facing the light-emitting layer, the opening of the second insulating layer can expose at least a portion of the first electrode or the second electrode, allowing it to contact the light-emitting layer or the auxiliary light-emitting functional layer. Each first effective light-emitting region and each second effective light-emitting region is defined by the portion of the first electrode or the second electrode that contacts the light-emitting layer or the auxiliary light-emitting functional layer. In some embodiments, the second insulating layer includes a pixel defining layer. In some embodiments, the auxiliary light-emitting functional layer can be any one or more layers selected from hole injection layer, hole transport layer, electron transport layer, hole blocking layer, electron blocking layer, electron injection layer, auxiliary light-emitting layer, interface improvement layer, anti-reflection layer, etc. In some embodiments, the first electrode can be an anode and the second electrode can be a cathode. In some embodiments, the first electrode can include at least two layers of indium tin oxide (ITO) and silver (Ag), such as a three-layer stack of ITO, Ag, and ITO. In some embodiments, the second electrode can include any one or more of magnesium (Mg), Ag, ITO, and indium zinc oxide (IZO), such as a mixed layer or alloy layer of Mg and Ag.

[0115] Each sub-pixel includes a light-emitting layer, each red sub-pixel 01 includes a first color light-emitting layer located inside the opening and on the pixel limiting layer, and each green sub-pixel 02 includes a second color light-emitting layer located inside the opening and on the pixel limiting layer.

[0116] For example, the arrangement of four green sub-pixels 02 surrounding one red sub-pixel 01 can be the arrangement within the display area, while the arrangement at the edge of the display area can differ from the arrangement within the display area. For example, at the edge of the display area, when the red sub-pixel 01 is in the first row or first column, or in the last row or last column, it can be surrounded by only two green sub-pixels 02. For example, if the shape of the display area edge is rounded, or if the display area is an irregularly shaped display area, such as a circular display area or a rectangular display area with a cutout area near a certain edge, the red sub-pixel 01 at the edge of the display area can be surrounded by one, two, or three green sub-pixels 02.

[0117] In some embodiments, the shapes of the light-emitting layer 101 of the red sub-pixel, the light-emitting layer 102 of the green sub-pixel, and the light-emitting layer 103 of the blue sub-pixel may be the same or substantially the same. The light-emitting layer located in the pixel defining layer defines the effective light-emitting area of ​​the sub-pixel. In embodiments of this disclosure, if the first corner of the blue sub-pixel 03 is a rounded chamfer or a flat chamfer, the distance from the vertex of the first corner of the blue sub-pixel 03 to the boundary of the light-emitting layer is not equal to the distance from the vertex of the other corners to the boundary of the light-emitting layer. For example, the distance from the vertex of the first corner of the blue sub-pixel 03 to the boundary of the light-emitting layer is greater than the distance from the vertex of the other corners to the boundary of the light-emitting layer.

[0118] In some embodiments, the nearest distance from the center of the green sub-pixel 02 in the first virtual quadrilateral 10 to the boundary of the light-emitting area of ​​the two directly adjacent red sub-pixels 01 is equal. Additionally, the nearest distance from the center of the green sub-pixel 02 to the boundary of the light-emitting area of ​​the two directly adjacent blue sub-pixels 03 is also equal. The ratio of the nearest distance from the center of the green sub-pixel 02 to the boundary of the light-emitting area of ​​the directly adjacent red sub-pixel 01 to the nearest distance to the boundary of the light-emitting area of ​​the directly adjacent blue sub-pixel 03 is approximately 0.8 to 1.2.

[0119] Specifically, Figure 5 This is a schematic diagram showing the distribution of the actual brightness center of a pixel array where the first corner of the blue sub-pixel 03 in this embodiment of the present disclosure is rounded and similar to a right angle; as shown... Figure 5 As shown, taking the example where the first corner of all blue sub-images in the pixel array faces right, where... Figure 5The dashed corner of the first corner of the blue sub-pixel 03 represents a pixel array in the related art where the first corner of the blue sub-pixel 03 is a near-right angle; "×" represents the actual brightness center of the pixel array when displayed in the related art; "·" represents the actual brightness center of the pixel array when displayed in the embodiment of this disclosure; by Figure 5 It can be seen that when the first corner of the blue pixel is rounded, its actual brightness distribution at the center is more uniform.

[0120] In some embodiments, the interior angles of the first virtual quadrilateral 10 range from approximately 70° to 110°, and it is preferred that the values ​​of the interior angles are closer to 90°. However, the fact that the interior angles of the first virtual quadrilateral 10 are between 70° and 110° does not constitute a limitation on the embodiments of this disclosure, as long as not all of the interior angles of the first virtual quadrilateral 10 are equal to 90°.

[0121] In some embodiments, the first virtual quadrilateral 10 may include, but is not limited to, a virtual parallelogram or a virtual trapezoid. For example, the first virtual quadrilateral 10 may be any one of a rhombus, an isosceles trapezoid, or a right trapezoid.

[0122] In some embodiments, Figure 6 This is a schematic diagram of a blue sub-pixel in one embodiment of the present disclosure; as shown below. Figure 6 As shown, the first corner of blue sub-pixel 03 is either rounded or flat-edged. The distance from the intersection of the extended lines of the two sides of the first corner to the vertex of the first corner is d1, and the distance from the vertex of the first corner to the vertex of the second corner is d2; the ratio of d1 to d2 is approximately 1 / 5 to 1 / 2. The vertex of the first corner of blue sub-pixel 03 is the point closest to the boundary of the sub-pixel, which is the intersection of the extended lines of the two sides of its corresponding vertex. Similarly, when the first corners of red sub-pixel 01 and green sub-pixel 02 are rounded or flat-edged, the distances from the intersection of the extended lines of the two sides of their respective first corners to the vertex of the first corner and the distances from the vertex of the first corner to the vertex of the second corner can also be set according to the above dimensions.

[0123] In some embodiments, the virtual apex angles formed by the intersection of the extended lines of the two sides of the corresponding apex angles of the second, third, and fourth corners of the blue sub-pixel 03 are approximately equal; or, the virtual apex angles formed by the intersection of the extended lines of the two sides of the corresponding apex angles of the second, third, and fourth corners of the blue sub-pixel 03 are around 90°, for example, approximately 80°-100°.

[0124] In some embodiments, the area enclosed by the extension lines on both sides of the apex of the first corner of the blue sub-pixel 03 and the outline of the first corner is the first hollow area, and the area enclosed by the extension lines on both sides of the apex of the second corner of the blue sub-pixel 03 and the boundary outline of the second corner is the second hollow area; wherein, the area of ​​the first hollow area is larger than the area of ​​the second hollow area.

[0125] Additionally, the area enclosed by the extended lines of the two sides of the apex of the third triangle of the blue sub-pixel 03 and the boundary outline of the third corner is the third cutout area; the area enclosed by the extended lines of the two sides of the apex of the fourth corner of the blue sub-pixel 03 and the boundary outline of the fourth corner is the fourth cutout area; in some embodiments, the areas of the second, third, and fourth cutout areas are approximately equal. For example, the areas of the second, third, and fourth cutout areas are all less than 4 μm²; the area of ​​the first cutout area is greater than 2 μm².

[0126] In some embodiments, Figure 7 This is a schematic diagram of a blue sub-pixel according to an embodiment of the present disclosure; as shown Figure 7 As shown, the first corner of the blue sub-pixel 03 is either rounded or flat. A straight line along the row direction from the center of the blue sub-pixel 03 divides it into two parts, with areas S1 and S2 respectively, where S1:S2 is approximately 2:8 to 8:2. Alternatively, a straight line along the column direction from the center of the blue sub-pixel 03 divides it into two parts, with areas S1 and S2 respectively, where S1:S2 is also approximately 2:8 to 8:2. Similarly, when the first corners of the red sub-pixel 01 and green sub-pixel 02 are rounded or flat, straight lines along the row and column directions from their respective centers divide their areas into the same proportions as the blue sub-pixel 03 described above.

[0127] In some embodiments, such as Figure 6 As shown, the first corner of the blue sub-pixel is rounded or flat-edged, and the virtual apex angle formed by the extensions of the two sides of its first corner is approximately 90°. In some embodiments, the angle of this virtual apex angle is approximately 80°-100°. Similarly, when the first corners of the red sub-pixel 01 and the green sub-pixel 02 are rounded or flat-edged, the angle between the extensions of the two sides of their respective first corners can be approximately the same as the angle between the extensions of the two sides of the first corner of the blue sub-pixel 03.

[0128] In some embodiments, the lines connecting the diagonal edges of red sub-pixels 01 and blue sub-pixels 03 located in the same row are approximately on the same straight line, or form an angle of about 30° with the row direction. Additionally, in some embodiments, Figure 8 This is a schematic diagram of a red sub-pixel and a blue sub-pixel located adjacent to each other in the same row in an embodiment of this disclosure, as shown below. Figure 8 As shown, in the first pixel row 1, that is, a red sub-pixel 01 and a blue sub-pixel 03 located adjacent to each other in the same row, the extension line of the line connecting the endpoints furthest from their respective centers on the first side (left) in the column direction intersects the extension line of the line connecting the endpoints furthest from their respective centers on the opposite second side (right), and the included angle is less than 30°.

[0129] In some embodiments, Figure 9 This is a schematic diagram of a red sub-pixel and a blue sub-pixel located adjacent to each other in the same row in an embodiment of this disclosure, as shown below. Figure 9 As shown, a red sub-pixel 01 and a blue sub-pixel 03 located adjacent to each other in the same column have their extended lines of the line connecting the endpoints furthest from their respective centers on the first side (top) of the row direction intersecting with the extended lines of the line connecting the endpoints furthest from their respective centers on the opposite second side (bottom), with an angle of less than 30°.

[0130] In some embodiments, at least one corner of an adjacent red sub-pixel 01 and at least one corner of a blue sub-pixel 03 in the same row are opposite each other, and the intersection of the extensions of the two sides of at least one corner of the red sub-pixel 01 and the intersection of the extensions of the two sides of at least one corner of the blue sub-pixel 03 lies on a straight line parallel to the row direction; and / or, at least one corner of an adjacent red sub-pixel 01 and at least one corner of a blue sub-pixel 03 in the same column are opposite each other, and the intersection of the extensions of the two sides of at least one corner of the red sub-pixel 01 and the intersection of the extensions of the two sides of at least one corner of the blue sub-pixel 03 lies on a straight line parallel to the column direction. In some embodiments, four first virtual quadrilaterals 10 arranged in an array constitute a second virtual polygon. For example, as... Figure 10 As shown, the second virtual polygon formed by the four first virtual quadrilaterals 10 arranged in an array is a quadrilateral structure, such as a rectangle (including a square). Of course, the second virtual polygon is not limited to quadrilaterals; it can also be hexagonal or other polygonal shapes. In this embodiment, a quadrilateral is used as an example for description, hereinafter referred to as the second virtual quadrilateral 100. The four green sub-pixels 02 in the second virtual quadrilateral 100 are arranged in an "X" shape. That is, the green sub-pixels 02 in the same row of the second virtual quadrilateral 100 are symmetrically arranged along the column direction, and the green sub-pixels 02 in the same column are symmetrically arranged along the row direction. In some embodiments, the red sub-pixel 01 within the second virtual quadrilateral 100 is located at the center and apex of the second virtual quadrilateral 100, and the blue sub-pixel 03 is located on the edge of the second virtual quadrilateral 100. The red sub-pixel 01 and the blue sub-pixel 03 located at the apex and edge of the second virtual quadrilateral 100 are alternately distributed in a clockwise direction at the edge and apex of the second virtual quadrilateral 100.

[0131] In some embodiments, within the second virtual quadrilateral 100, the centers of blue sub-pixels 03 located in the same row are approximately on a straight line in the parallel row direction, and / or, the centers of blue sub-pixels 03 located in the same column are approximately on a straight line in the parallel row direction.

[0132] In some embodiments, within the second virtual quadrilateral 100, the centers of green sub-pixels 02 located in the same row are approximately on a straight line in the parallel row direction, and / or the centers of green sub-pixels 03 located in the same column are approximately on a straight line in the parallel row direction.

[0133] In some embodiments, the red sub-pixels 01, green sub-pixels 02, and blue sub-pixels 03 in the pixel array have the same shape. Of course, different shapes can also exist in the sub-pixels of various colors, and the different shapes are evenly distributed in the sub-pixels of various colors. For example, the red sub-pixels 01 with the same shape are spaced out in every row or column.

[0134] In some embodiments, if the first corner of the blue sub-pixel 03 is rounded or flat, the orientation of the first corner of each blue sub-pixel 03 in the pixel array can be the same or partially the same. For example, the first corners of blue sub-pixels 03 located in the same row have the same orientation, while the first corners of blue sub-pixels 03 located in the same column have different orientations. Similarly, the first corners of green sub-pixels 02 and red sub-pixels 01 can be rounded or flat, and can be arranged according to the orientation of the first corner of the blue sub-pixels 03.

[0135] This disclosure also provides a pixel array, which is substantially the same as the pixel array described above; the pixel array includes multiple sub-pixels, including red sub-pixels 01, green sub-pixels 02, and blue sub-pixels 03; red sub-pixels 01 and blue sub-pixels 03 are alternately arranged along the row direction to form multiple rows of first pixel rows 1, and red sub-pixels 01 and blue sub-pixels 03 located in the same column of the multiple rows of first pixel rows 1 are alternately arranged; green sub-pixels 02 are arranged side by side along the row direction to form multiple rows of second pixel rows 2; the centers of two red sub-pixels 01 and two blue sub-pixels arranged in an array are... The secondary connections form a first virtual quadrilateral 10, and a green sub-pixel is set within each first virtual quadrilateral 10; wherein at least some interior angles of the first virtual quadrilateral 10 are not equal to 90°; the shapes of the red sub-pixel 01, green sub-pixel 02, and blue sub-pixel 03 include polygons, and the distance from the intersection of the extensions of the two sides of at least one vertex of at least one polygonal sub-pixel to the nearest boundary of the sub-pixel is not equal to the distance from the intersection of the extensions of the two sides of the other vertex of the sub-pixel to the nearest boundary of the sub-pixel. For example: Refer to Figure 6The first corner of the blue sub-pixel 03 is either rounded or flat. The distance from the intersection of the extensions of the two sides of the first corner to the vertex of the first corner is d1, and the distance from the vertex of the first corner to the vertex of the second corner is d2. The ratio of d1 to d2 is approximately 1 / 5 to 1 / 2. The vertex of the first corner of the blue sub-pixel 03 is the point closest to the boundary of the sub-pixel, which is the intersection of the extensions of the two sides of the corresponding vertex.

[0136] In some embodiments, the red sub-pixels 01 are axially symmetric graphics, and all red sub-pixels 01 have the same shape, but at least some of the red sub-pixels 01 have symmetry axes that are not in the same direction; or, the green sub-pixels 02 are axially symmetric graphics, and all green sub-pixels 02 have the same shape, but at least some of the green sub-pixels 02 have symmetry axes that are not in the same direction; or, the blue sub-pixels 03 are axially symmetric graphics, and all blue sub-pixels 03 have the same shape, but at least some of the blue sub-pixels 03 have symmetry axes that are not in the same direction. For example, the first corner of the blue sub-pixels 03 is a rounded chamfer or a flat chamfer. All blue sub-pixels 03 in the pixel array have the same shape, but the orientation of the first corner is different. Some of the first corners face upwards, and some face left. The symmetry axis of the blue sub-pixels 03 with the first corner facing upwards is parallel to the column direction, while the symmetry axis of the blue sub-pixels 03 with the first corner facing left is parallel to the row direction. That is, the symmetry axes of the blue sub-pixels 03 with the first corner facing upwards and left are in the same direction.

[0137] In some embodiments, the red sub-pixel 01 and the blue sub-pixel 03 are axially symmetric graphics, and at least some of the axes of symmetry of the red sub-pixel 01 and the blue sub-pixel 03 are not in the same direction. For example, the first corners of both the red sub-pixel 01 and the blue sub-pixel 03 are rounded or flat-edged, and the first corner of a portion of the red sub-pixel 01 faces upwards, with its axis of symmetry parallel to the column direction, while the first corner of a portion of the blue sub-pixel 03 faces left, with its axis of symmetry parallel to the row direction; that is, the axes of symmetry of the red sub-pixel 01 and the blue sub-pixel 03 with different first corner orientations are not in the same direction.

[0138] In some embodiments, the shape of the green sub-pixel 02 can be an asymmetrical shape, such as a right trapezoid.

[0139] In some embodiments, at least one shape of the red sub-pixel 01 and the blue sub-pixel 03 includes only one axis of symmetry; for example, the first corner of at least one shape of the red sub-pixel 01 and the blue sub-pixel 03 is a rounded chamfer or a flat chamfer, while the second, third, and fourth corners of the red sub-pixel 01 and the blue sub-pixel 03 are approximately the same, in which case at least one shape of the red sub-pixel 01 and the blue sub-pixel 03 includes only one axis of symmetry.

[0140] In some embodiments, at least two of the following are different: the number of symmetry axes of the shape of red sub-pixel 01, the number of symmetry axes of the shape of green sub-pixel 02, and the number of symmetry axes of the shape of blue sub-pixel 03. For example: one of red sub-pixel 01, green sub-pixel 02, and blue sub-pixel 03 can be an axially symmetric shape, while the other two are not axially symmetric shapes; or two of them are axially symmetric shapes, while the third is not; or all three are axially symmetric shapes, but the number of the three symmetry axes is different, for example, the three have one, two, and four symmetry axes respectively; or all three are axially symmetric shapes, but the number of one symmetry axis is different from the other two, for example, two have one symmetry axis, and the other has two or four symmetry axes, etc. The pixel array in the embodiments of this disclosure will be described below with reference to specific examples.

[0141] First example, Figure 10 for Figure 4 The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; where, as shown... Figure 10 As shown, it only illustrates the arrangement of sub-pixels within the four second virtual quadrilaterals 100; as Figure 4 and 7 As shown, each second virtual quadrilateral 100 includes four first virtual quadrilaterals 10, with adjacent first virtual quadrilaterals 10 sharing a common edge, and adjacent second virtual quadrilaterals 100 sharing a common edge. Each first virtual quadrilateral 10 is formed by connecting the centers of two red sub-pixels 01 and two blue sub-pixels 03 arranged in an array. That is, two red sub-pixels 01 and two blue sub-pixels 03 are respectively placed at the four vertices of each first virtual quadrilateral 10, with the two red sub-pixels 01 placed at two opposite vertices of the first virtual quadrilateral 10, and the two blue sub-pixels 03 placed at the other two opposite vertices of the first virtual quadrilateral 10. A green sub-pixel 02 is placed at the center of each first virtual quadrilateral 10. For the arrangement of sub-pixels within each second virtual quadrilateral 100, red sub-pixels 01 are placed at the center and four vertices of the second sub-pixels, and a blue sub-pixel 03 is placed between two red sub-pixels 01 in the row and column directions.

[0142] like Figure 10 As shown, the first corner of the blue sub-pixel 03 is rounded, and the second, third, and fourth corners all include similar right angles. For each second virtual quadrilateral 100, two blue pixels in the same row are symmetrically arranged along the column direction, and two blue sub-pixels 03 in the same column are symmetrically arranged along the row direction. For two adjacent first pixel rows 1, the first corners of each blue sub-pixel 03 in one row have the same orientation, while the first corners of each blue sub-pixel 03 in the other row have opposite orientations.

[0143] like Figure 10 As shown, the first virtual quadrilateral 10 in the upper left corner has a pair of equal angles (92° in the illustration) and another angle of 90°. The other virtual quadrilaterals 10 have at least one angle of 90°, and the vertex of the 90° angle is located at the center of the red pixel. The diagonal blue sub-pixels 03 around each red sub-pixel 01 are centrally symmetrical about the red sub-pixel 01.

[0144] like Figure 10 As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 10 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the light-emitting areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b.

[0145] Second example, Figure 13 This is a schematic diagram of a pixel array in a second example of an embodiment of this disclosure; as shown Figure 13 As shown, the positions and shapes of each sub-pixel in this pixel array are the same as those in the pixel array of the first example, the only difference being the orientation of the first corner of some blue sub-pixels 03. In this pixel array, the first corners of all blue sub-pixels 03 located in the same row have the same orientation, and the first corners of all blue sub-pixels 03 located in the same column also have the same orientation. For example: Figure 13 The first corners of all blue sub-pixels 03 in the first row are facing upwards; the first corners of all blue sub-pixels 03 in the first column are facing left.

[0146] Figure 10 for Figure 13 The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; as shown. Figure 10 As shown, the first virtual quadrilateral 10 in the upper left corner of the second virtual quadrilateral 100 has a pair of equal angles (92° in the illustration) and another angle of 90°. The other first virtual quadrilaterals 10 have at least one angle of 90°, and the vertex of the 90° angle is located at the center of the red pixel. The blue sub-pixels 03 at the two opposite corners of each first virtual sub-quadrilateral are symmetrically arranged about the center lines of the two red sub-pixels 01.

[0147] like Figure 10As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 10 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the luminous areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b. Third example, Figure 13 This is a schematic diagram of a pixel array in a third example of an embodiment of this disclosure; as shown Figure 13 As shown, the positions and shapes of each sub-pixel in this pixel array are the same as those in the pixel arrays of the two examples above, the only difference being the orientation of the first corner of some blue sub-pixels 03. In this pixel array, the orientation of the first corner of all blue sub-pixels 03 is the same. For example: Figure 13 The first corner of all blue sub-pixels 03 faces left.

[0148] Figure 14 for Figure 13 The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; as shown. Figure 14 As shown, the first virtual quadrilateral 10 in the upper left corner of the second virtual quadrilateral 100 is an isosceles trapezoid with two angles of 92° and the other two angles of 88°.

[0149] like Figure 14 As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 14 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the light-emitting areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b.

[0150] Fourth example, Figure 15 This is a schematic diagram of the pixel array in the fourth example of an embodiment of this disclosure; as shown Figure 15As shown, the positions and shapes of the sub-pixels in this pixel array are the same as those in the pixel arrays of the three examples above, the only difference being the orientation of the first corner of some blue sub-pixels 03. In this pixel array, the first corners of the blue sub-pixels 03 in the same row have the same orientation, and the first corners of the blue sub-pixels 03 in the first pixel row 1 of odd-numbered rows have opposite orientations to those in the first pixel row 1 of even-numbered rows. For example, the first corners of the blue sub-pixels 03 in the first pixel row 1 of the first row all face right, and the first corners of the blue sub-pixels 03 in the first pixel row 1 of the second row all face left.

[0151] Figure 16 for Figure 15 The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; as shown. Figure 16 As shown, the first virtual quadrilateral 10 in the upper left corner of the second virtual quadrilateral 100 has an obtuse angle of 92° and another obtuse angle of 88°.

[0152] like Figure 16 As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 16 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the light-emitting areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b.

[0153] Fifth example, Figure 17 This is a schematic diagram of the pixel array in the fifth example of an embodiment of this disclosure; as shown Figure 17 As shown, the positions and shapes of the sub-pixels in this pixel array are the same as those in the pixel arrays of the four examples above, the only difference being the orientation of the first corner of some blue sub-pixels 03. In this pixel array, the first corners of all blue sub-pixels 03 located in the same row have the same orientation, and the first corners of all blue sub-pixels 03 located in the same column also have the same orientation. For example: Figure 17 The first corners of all blue sub-pixels 03 in the first row are facing upwards; the first corners of all blue sub-pixels 03 in the first column are facing left.

[0154] Figure 18 for Figure 17The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; as shown. Figure 18 As shown, the first virtual quadrilateral 10 in the upper left corner of the second virtual quadrilateral 100 has one pair of equal angles of 90°, and the other pair of angles are 92° and 88° respectively.

[0155] like Figure 18 As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 18 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the light-emitting areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b.

[0156] It should be noted that the above examples do not constitute a limitation on the arrangement of each blue sub-pixel 03 in the embodiments of this disclosure. As long as any blue sub-pixel 03 is rotated at any angle along the midpoint of the line connecting the centers of its adjacent red sub-pixels 01 in the row direction, the resulting pixel array is within the protection scope of the embodiments of this disclosure.

[0157] In some embodiments, the blue sub-image 03 has only a rounded or flat chamfered first corner, and the first corner is always facing upwards. In this case, the lines connecting the vertices of the two opposite corners (the third and fourth corners) of the red sub-pixel 01 and the blue sub-image 03 in the row direction are approximately on the same straight line. The lines connecting the vertices of the first and second corners of the red sub-pixel 01 and the second corner of the blue sub-image 03 in the same column are also approximately on the same straight line.

[0158] The first to fifth examples above all illustrate the concept of a rounded corner in the first corner of the blue sub-pixel 03. In some embodiments, Figure 19 This is a schematic diagram of a pixel array in which the first corner of the blue sub-pixel is chamfered, according to an embodiment of this disclosure; as shown Figure 19As shown, the positions, shapes, and arrangements of each sub-pixel in this pixel array are the same as those in the pixel array of the fourth example described above. In this pixel array, the first corners of all blue sub-pixels 03 located in the same row face the same direction, and the first corners of the blue sub-pixels 03 in the first pixel row 1 of odd-numbered rows face opposite directions to those in the first pixel row 1 of even-numbered rows. For example, the first corners of all blue sub-pixels 03 in the first pixel row 1 of the first row face right, and the first corners of all blue sub-pixels 03 in the first pixel row 1 of the second row face left.

[0159] Figure 20 for Figure 19 The diagram shows the distribution of sub-pixels within the first and second virtual quadrilaterals in the upper left corner of the pixel array; as shown. Figure 20 As shown, the first virtual quadrilateral 10 in the upper left corner of the second virtual quadrilateral 100 has an obtuse angle of 91° and another obtuse angle of 89°.

[0160] like Figure 20 As shown, assuming the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the same column is L, the second virtual quadrilateral 100 is a square with a side length of 2L, and its center is a red sub-pixel 01. The center of the green sub-pixel 02 within each first virtual quadrilateral 10 is located on the midline of the line connecting the centers of adjacent red sub-pixels 01 and blue sub-pixels 03 in the row or column direction. Additionally, as... Figure 20 As shown, the vertical distances from the center of the green sub-pixel 02 within each first virtual quadrilateral 10 to the boundaries of the light-emitting areas of the red sub-pixel 01 and the blue sub-pixel 03 are a and b, respectively, where a = b.

[0161] Furthermore, in the examples above, the first corner of the blue sub-pixel 03 is different from its other three corners; that is, the distance from the vertex of the first corner of the blue sub-pixel 03 to the center of the sub-pixel is less than the distance from the vertices of the other triangles to the center of the sub-pixel. In some embodiments, the first corner of at least one of the red sub-pixel 01 and the green sub-pixel 02 may also be designed in the shape of the blue sub-pixel 03 described above. The following explanation is based on specific examples.

[0162] Figure 21 This is a schematic diagram of a pixel array where the first corner of the red sub-pixel is flat-beveled, according to an embodiment of this disclosure; as shown... Figure 21As shown, the first corner of each red sub-pixel 01 in this pixel array faces to the right. Of course, the center of the red sub-pixel 01 can be changed by rotating the first corner of the red sub-pixel 01 so that the first corner of the red pixel faces in any direction. After rotating the first corner of the red sub-pixel 01, it can be arranged in the same way as the blue sub-pixel 03 described above. Figure 22 This is a schematic diagram showing the distribution of the actual brightness center of a pixel array with rounded corners and near-right angles at the first corner of the red sub-pixel in an embodiment of this disclosure; as shown... Figure 22 As shown, taking the example where the first corner of all red sub-images in the pixel array faces right, where... Figure 22 The dashed corner of the first corner of the blue sub-pixel 03 represents a pixel array where the first corner of the red sub-pixel 01 is a near-right angle; "×" represents the actual brightness center of the pixel array when displayed in the related technology; "·" represents the actual brightness center of the pixel array when displayed in the embodiment of this disclosure; by Figure 22 It can be seen that when the first corner of the red pixel is rounded, its actual brightness distribution at the center is more uniform.

[0163] Figure 23 This is a schematic diagram of a pixel array in which the first corner of the green sub-pixel is flat-beveled, according to an embodiment of this disclosure; as shown Figure 23 As shown, in this pixel array, the four green sub-pixels 02 in each second virtual quadrilateral 100 have different orientations for their first corners, with two green sub-pixels 02 located in the same column arranged symmetrically about the row direction. Of course, the first corner of the green sub-pixel 02 can be rotated to face any direction, thus changing the center of the green sub-pixel 02. After rotating the first corner of the green sub-pixel 02, it can be arranged in the same way as the blue sub-pixel 03 described above.

[0164] Figure 24 This is a schematic diagram of a pixel array in which the first corners of the red and blue sub-pixels of an embodiment of this disclosure are flattened. As shown in 22, the first corners of each red sub-pixel 01 in the same row face the same direction, and the first corners of each blue sub-pixel 03 in the same row face the same direction. The first corners of the red and blue sub-pixels in the same row face opposite directions. Of course, the first corners of the red and blue sub-pixels 01 and 03 can be rotated to make them face in any direction, thereby changing the center of the red and blue sub-pixels 01 and 03. After rotating the first corners of the red and blue sub-pixels 01 and 03, they can be arranged in the same way as the blue sub-pixels 03 described above.

[0165] Secondly, embodiments of this disclosure also provide a display device, including any of the display panels described above. This display device can be any product or component with display functionality, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0166] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
