Description

[Technical Field]

[0001] The present invention is in the field of display technology, and more particularly to pixel arrays and display devices. [Background technology]

[0002] Currently, organic electroluminescence (organic light emitting diode, OLED) display devices have become one of the hotspots in the research field of flat panel displays. Compared with liquid crystal displays (LCDs), OLED display devices have advantages such as low power consumption, low production costs, self-luminescence, wide viewing angle, and fast response time. OLED display devices are now beginning to replace traditional liquid crystal displays (LCDs) in flat panel displays for mobile phones, tablets, digital cameras, etc.

[0003] An OLED display device mainly comprises a substrate and pixels formed on the substrate in an array. For each pixel, an organic electroluminescent element is generally formed at the corresponding pixel position on the array substrate using a deposition technique using an organic material through a high-definition metal mask plate.

[0004] However, in current OLED displays, the pixel spacing is relatively large, resulting in a relatively small pixel aperture area for the same resolution. Therefore, the driving current must be increased to meet the display brightness requirements. However, operating an OLED under a large driving current tends to accelerate the degradation rate of the device, shortening the lifespan of the OLED display.

DETAILED DESCRIPTION OF THE INVENTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0040] Unless otherwise defined, technical or scientific terms used herein have their ordinary meanings as understood by those skilled in the art. The terms "first," "second," and similar terms used herein do not denote any order, number, or importance, but are merely used to distinguish between different components. Similarly, terms such as "one," "an," or "the" do not limit the number but indicate at least one. Terms such as "comprise" mean that the element or item preceding the term encompasses the element or item described thereafter and its equivalents, and do not exclude other elements or items. Terms such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "top," "bottom," "left," and "right" are used only to indicate relative positional relationships, and if the absolute position of the described objects changes, the relative positional relationships may change accordingly.

[0041] In addition, the row direction and column direction in the embodiments of the present invention merely represent two different directions, and are not limited to being perpendicular to each other. In the drawings of the embodiments of the present invention, only the case where the row direction and column direction are perpendicular to each other is described as an example, but this does not limit the embodiments of the present invention.

[0042] Furthermore, in the embodiments of the present invention, the terms "identical" and "equal" do not mean that the dimensions of two items are completely equal or that the shapes are completely identical, but rather that they are approximately identical within a certain range of error, and cases where they are approximately equal are acceptable.

[0043] Before describing the pixel array, display device, and high-precision mask plate of the embodiments of the present invention, the concepts of subpixels, first subpixels, second subpixels, and third subpixels will be explained below. In the embodiments of the present invention, the pixel array refers to the arrangement structure of light-emitting elements of different colors on a display substrate, and the arrangement structure of the pixel circuits driving each light-emitting element is not limited. Similarly, in the embodiments of the present invention, the subpixel refers to the structure of the light-emitting elements, and it will be understood that the first subpixel, second subpixel, and third subpixel represent three subpixels of different colors. In the embodiments of the present invention, the first subpixel is a red subpixel, the second subpixel is a green subpixel, and the third subpixel is a blue subpixel will be described as an example. However, the fact that the first subpixel is a red subpixel, the second subpixel is a green subpixel, and the third subpixel is a blue subpixel does not limit the scope of protection of the embodiments of the present invention.

[0044] Typically, the shape of each sub-pixel is determined by a pixel aperture in the pixel definition layer, and forming at least a portion of the light-emitting layer in the pixel aperture defines the shape of the light-emitting area of ​​the sub-pixel, i.e., the shape of the sub-pixel in the embodiment of the present invention. When the pixel aperture is rectangular, the sub-pixel is rectangular.

[0045] In the embodiments of the present invention, at least one of the red, green, and blue subpixels has a polygonal shape. The following describes an example in which the red, green, and blue subpixels are all polygonal. A polygon may have three or more corners depending on its shape. For example, a square or a shape close to a square may have four vertices. FIG. 3a is a schematic diagram of a polygon, and FIG. 3b is a schematic diagram of another polygon. As shown in FIGS. 3a and 3b, each polygon has four vertices, namely, a first corner, a second corner, a third corner, and a fourth corner, with the first corner facing the second corner and the third corner facing the fourth corner. It should be understood that a polygonal subpixel may have more vertices, and this is not a limitation of the embodiments of the present invention. In the embodiments of the present invention, a so-called apex angle does not necessarily mean an angle between two lines. In practice, the two sides of a vertex angle that extend toward the vertex and intersect with each other may be formed as a single arc or straight line segment, resulting in a chamfered or flattened vertex. As shown in Figures 3a and 2b, the embodiments of the present invention describe a case in which the first corner 11 of at least one of the blue, red, and green subpixels is chamfered or flattened, while the other corners are nearly right angles. However, this is not intended to limit the scope of the present invention. The second, third, and fourth corners are substantially identical, e.g., nearly right angles. That is, these three corners may be rounded, but the radius of curvature of the corresponding roundness is relatively small, smaller than the radius of curvature of the first corner. In addition, the second corner, the third corner, and the fourth corner being approximately identical means, for example, that these three angles are identical, that the contours are identical, that the sizes are identical, and that the curvatures of the roundness are identical.

[0046] In order to clarify the structure of each sub-pixel in the pixel array of the embodiment of the present invention, the structure of the film layer of the pixel array of the embodiment of the present invention will be described below with reference to the manufacturing method of the pixel array. Figure 1 is a structural schematic diagram of the film layer of an exemplary pixel array. As shown in Figure 1, the method may specifically include the following steps:

[0047] (1): A base substrate is prepared on a glass carrier plate.

[0048] In some exemplary embodiments, the base substrate 10 may be a flexible base substrate, for example, 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 carrier plate. The first flexible material layer and the second flexible material layer may be made of a material such as polyimide (PI), polyethylene terephthalate (PET), or a surface-treated polymer soft film. The first inorganic material layer and the second inorganic material layer may be made of silicon nitride (SiNx) or silicon oxide (SiOx), etc., to improve the water resistance and oxidation resistance of the base substrate. The first inorganic material layer and the second inorganic material layer are also called barrier layers. The semiconductor layer may be made of amorphous silicon (a-Si). In some exemplary embodiments, taking a laminated structure PI1 / Barrier1 / a-si / PI2 / Barrier2 as an example, the fabrication process includes: first, applying a layer of polyimide to a glass carrier plate 1 and curing it to form a first flexible (PI1) layer; then, depositing a layer of barrier thin film on the first flexible layer to form a first barrier (Barrier1) layer covering the first flexible layer; then, depositing a layer of amorphous silicon thin film on the first barrier layer to form an amorphous silicon (a-si) layer covering the first barrier layer; then, applying a layer of polyimide on the amorphous silicon layer and curing it to form a second flexible (PI2) layer; and then, depositing a layer of barrier thin film on the second flexible layer to form a second barrier (Barrier2) layer covering the second flexible layer, completing the fabrication of the base substrate 10, as shown in FIG. 6.

[0049] (2): A driving structure layer is fabricated on the base substrate. The driving structure layer includes a plurality of driving circuits, each of which includes a plurality of transistors and at least one storage capacitor, and is designed as, for example, 2T1C, 3T1C, or 7T1C. Take the case where there are three subpixels, and each subpixel driving circuit only has one transistor and one storage capacitor.

[0050] In some embodiments, the fabrication process of the driving structure layer may refer to the following description: The fabrication process of the driving circuit for the red sub-pixel 01 will be described as an example.

[0051] A first insulating thin film and an active layer thin film are deposited in sequence on the base substrate 10, and the active layer thin film is patterned by a patterning process to form a first insulating layer 011 that covers the entire base substrate 010 and an active layer pattern that is provided on the first insulating layer 011 and includes at least the first active layer.

[0052] Next, a second insulating thin film and a first metal thin film are deposited in this order, and the first metal thin film is patterned by a patterning process to form a second insulating layer 012 that covers the active layer pattern and a first gate metal layer pattern that is provided on the second insulating layer 012 and includes at least a first gate electrode and a first capacitance electrode.

[0053] Next, a third insulating thin film and a second metal thin film are deposited in this order, and the second metal thin film is patterned by a patterning process to form a third insulating layer 013 covering the first gate metal layer and a pattern of the second gate metal layer provided on the third insulating layer 013 and including at least a second capacitance electrode, and the position of the second capacitance electrode corresponds to the position of the first capacitance electrode.

[0054] Next, a fourth insulating thin film is deposited, and the fourth insulating thin film is patterned by a patterning process to form a pattern of the fourth insulating layer 014 covering the second gate metal layer, and at least two first vias are opened in the fourth insulating layer 014, and 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.

[0055] Next, a third metal thin film is deposited and patterned by a patterning process to form a source-drain metal layer pattern including at least a first source electrode and a first drain electrode located in the display region on the fourth insulating layer 014. The first source electrode and the first drain electrode may each be connected to the first active layer through a first via.

[0056] In the driving circuit for the red subpixel 01 in the display region, the first active layer, the first gate electrode, the first source electrode, and the first drain electrode may form a first transistor 210, and the first capacitance electrode and the second capacitance electrode may form a first storage capacitor 212. In the above-mentioned fabrication process, the driving circuit for the green subpixel 02 and the driving circuit for the blue subpixel 03 may be formed simultaneously.

[0057] In some exemplary embodiments, the first insulating layer 011, the second insulating layer 012, the third insulating layer 013, and the fourth insulating layer 014 may be single-layered, multi-layered, or composite layers using one or more of silicon oxide (SiOx), silicon nitride (SiNx), and silicon oxynitride (SiON). The first insulating layer 011 is called a buffer layer and is used to improve the water resistance and oxidation resistance of the base substrate. The second insulating layer 012 and the third insulating layer 013 are called gate insulator (GI) layers, and the fourth insulating layer 014 is called an interlayer dielectric (ILD) layer. The first, second, and third metal thin films are made of one or more metal materials, such as silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), and molybdenum (Mo), or alloy materials of the above metals, such as aluminum-neodymium alloy (AlNd) or molybdenum-tungsten alloy (MoNb). They may have a single-layer structure or a multilayer composite structure, such as Ti / Al / Ti. The active layer thin film is made of 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), sexithiophene, and polythiophene. This invention applies to transistors fabricated using oxide, silicon, and organic technologies.

A plurality of second vias are formed in the planarization layer 015 in the display area by masking, exposing, and developing processes. The planarization layer 015 in the plurality of second vias is developed and removed to expose the surface of the first drain electrode of the first transistor 210 in the driving circuit for the red subpixel 01, the surface of the first drain electrode of the first transistor in the driving circuit for the green subpixel 02, and the surface of the first drain electrode of the first transistor in the driving circuit for the blue subpixel 03, respectively.

[0060] (4): A first electrode pattern is formed on the base substrate on which the pattern has been formed. In some examples, the first electrode is a reflective anode.

[0061] In some exemplary embodiments, a conductive thin film is deposited on the patterned base substrate 010, and then patterned through a patterning process to form a first electrode pattern. The first anode 213 of the red subpixel 01 is connected to the first drain electrode of the first transistor 210 through a second via, the second anode 223 of the green subpixel 022 is connected to the first drain electrode of the first transistor of the green subpixel 02 through a second via, and the third anode 233 of the blue subpixel 03 is connected to the first drain electrode of the first transistor of the blue subpixel 03 through a second via.

[0062] In some examples, the first electrode may be made of one or more metal materials such as magnesium (Mg), silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), and molybdenum (Mo), or an alloy material of the above metals such as aluminum neodymium alloy (AlNd) or molybdenum tungsten alloy (MoNb), and may be a single layer, a multilayer composite structure such as Ti / Al / Ti, or a stack structure made of a metal and a transparent conductive material, such as ITO / Ag / ITO or Mo / AlNd / ITO.

[0063] (5) A pixel definition layer (PDL) pattern is formed on the base substrate on which the above-described pattern has been formed.

[0064] In some exemplary embodiments, a pixel-defining thin film is coated on the base substrate 010 on which the above-mentioned pattern is formed, and a pattern of the pixel-defining layer is formed by masking, exposing, and developing processes. As shown in Figure 12, the pixel-defining layer 30 in the display area includes a plurality of sub-pixel defining portions 302, and a plurality of pixel-defining layer openings 301 are formed between adjacent sub-pixel defining portions 302. The pixel-defining layer 30 in the plurality of pixel-defining layer openings 301 is developed and removed to expose at least a portion of the surface of the first anode 213 of the red sub-pixel 01, at least a portion of the surface of the second anode 223 of the green sub-pixel 02, and at least a portion of the surface of the third anode 233 of the blue sub-pixel 03, respectively.

[0065] In some examples, pixel defining layer 30 may include polyimide, acrylic, polyethylene terephthalate, or the like.

[0066] (6) A post spacer (PS) pattern is formed on the base substrate on which the above-mentioned pattern has been formed.

[0067] In some exemplary embodiments, an organic material thin film is coated on the base substrate 010 on which the above-described pattern has been formed, and a pattern of post spacers 34 is formed by masking, exposing, and developing processes. The post spacers 34 may function as a support layer and are arranged to support the FMM during deposition. In some examples, two adjacent post spacers 34 are spaced apart by one repeat unit along the row arrangement direction of the subpixels. For example, a post spacer 34 may be located between adjacent red subpixel 01 and blue subpixel 03.

[0068] (7): An organic functional layer and a second electrode are sequentially formed on the base substrate on which the aforementioned pattern is formed. In some examples, the second electrode is a transparent cathode. The light-emitting element may emit light from the side away from the base substrate 010 through the transparent cathode to achieve top emission. In some examples, the organic functional layer of the light-emitting element includes a hole injection layer, a hole transport layer, an emitting layer, and an electron transport layer.

[0069] In some exemplary embodiments, a hole injection layer 241 and a hole transport layer 242 are sequentially deposited on the base substrate 010 having the above-described pattern formed thereon 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 FMM. Then, 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, the hole transport layer 242, the electron transport layer 243, and the cathode 244 are all common layers for multiple subpixels. 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.

[0070] In some exemplary embodiments, an organic functional layer is formed in the sub-pixel region to achieve a connection between the organic functional layer and the anode, and a cathode is formed in the pixel defining layer and connected to the organic functional layer.

[0071] In some exemplary embodiments, the cathode may be made of any one or more of magnesium (Mg), silver (Ag), aluminum (Al), an alloy of any one or more of the aforementioned metals, a transparent conductive material such as indium tin oxide (ITO), or a multi-layer composite structure of a metal and a transparent conductive material.

[0072] In some exemplary embodiments, an optical coupling layer may be formed on the side of the cathode 244 away from the base substrate 10, and the optical coupling layer may be a common layer for multiple subpixels. The optical coupling layer may function in cooperation with the transparent cathode to increase light output. For example, the optical coupling layer may be made of a semiconductor material. However, this embodiment is not limited thereto.

[0073] (8) A sealing layer is formed on the base substrate on which the above-mentioned pattern is formed.

[0074] In some exemplary embodiments, an encapsulation layer is formed on the base substrate 010 on which the above-described 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 thereto. In some examples, the encapsulation layer may have a five-layer structure of inorganic / organic / inorganic / organic / inorganic.

[0075] Figure 2 is a schematic diagram of an exemplary pixel array. As shown in Figure 2, the pixel array includes a plurality of first pixel rows 1 and a plurality of second pixel rows 2, where the first pixel rows 1 and the second pixel rows 2 are arranged alternately. The first pixel row 1 is formed by alternating red subpixels 01 and blue subpixels 03, and the red subpixels 01 and blue subpixels 03 located in the same column in the plurality of first pixel rows 1 are also arranged alternately. The second pixel row 2 is formed by juxtaposing a plurality of green subpixels 02, where the green subpixels 02 are arranged alternately with the red subpixels 01 and blue subpixels 03 in the adjacent row. In such a pixel arrangement, the pixel array may be divided into repeating units arranged in an array, each repeating unit including two rows and four columns of subpixels, i.e., each repeating unit including one red subpixel 01, one blue subpixel 03, and two green subpixels 02, where the red subpixel 01 and the blue subpixel 03 are common subpixels, and a virtualization algorithm may be used to display two virtual pixel units using four subpixels. For example, one virtual pixel unit may be formed by the red subpixel 01 in the second repeating unit in the first row, the blue subpixel 03 in the first repeating unit in the first row, and the green subpixel 02 closest to them, and another virtual pixel unit may be formed by the red subpixel 01 in the second repeating unit in the first row, the blue subpixel 03 in that repeating unit, and the green subpixel 02 closest to them. In addition, a blue subpixel 03 in the second repeating unit of the first row, another green subpixel 02 in the repeating unit, and the nearest red subpixel 01 in the third repeating unit of the first row form a virtual pixel unit, which can effectively improve the resolution of a display panel to which the pixel array is applied.

[0076] However, the inventors have found that the red subpixel 01 and the blue subpixel 03 are common subpixels, and that their areas are larger than the green subpixel 02 according to their emission spectra. In particular, the area of ​​the blue subpixel 03 is even larger than that of the red subpixel 01. Therefore, when the display panel displays, the actual brightness centers formed by each virtual pixel unit are not uniform. Therefore, the embodiments of the present invention provide the following technical solution:

[0077] In a first aspect, FIG. 4 is a schematic diagram of a pixel array according to an embodiment (first example) of the present invention. As shown in FIG. 4, the embodiment of the present invention provides a pixel array including a plurality of first pixel rows 1 and a plurality of second pixel rows 2, with the first pixel rows 1 and the second pixel rows 2 arranged alternately. The first pixel row 1 is formed by alternating red subpixels 01 and blue subpixels 03, and the red subpixels 01 and blue subpixels 03 located in the same column in the plurality of first pixel rows 1 are also arranged alternately. The second pixel row 2 is formed by juxtaposing a plurality of green subpixels 02, with the green subpixels 02 alternating with the red subpixels 01 and blue subpixels 03 in adjacent rows. The centers of two red subpixels 01 and two blue subpixels 03 arranged in an array are connected in order to form first virtual rectangles 10, and one green subpixel 02 is provided within each first virtual rectangle 10. At least some of the interior angles of the first imaginary rectangle 10 are not equal to 90°. The shapes of the red subpixel 01, the green subpixel 02, and the blue subpixel 03 all include polygons, and in at least one of these three subpixels that has a polygonal shape, the distance from the intersection of the extensions of two sides of at least one vertex angle to the center of the subpixel is not equal to the distance from the intersection of the extensions of two sides of the opposite corner to the center of the subpixel.

[0078] In the embodiments of the present invention, the polygon includes, but is not limited to, a rounded polygon, a convex polygon, and a concave polygon. The subpixel center is, for example, the geometric center of the subpixel, the intersection of the perpendicular bisectors of each side of the subpixel, or a point on the subpixel that is approximately equidistant from each side. Of course, a certain margin of error is allowed for the location of the subpixel center. For example, the subpixel center is any point within a 3 μm radius of the geometric center of the subpixel.

[0079] In an embodiment of the present invention, the shapes of some subpixels are adjusted so that at least some of the interior angles of the first virtual rectangle 10 formed by connecting the centers of the red subpixel 01 and the blue subpixel 03 are not equal to 90°, and the distance from the intersection of the extension lines of two sides of at least one vertex angle in at least one of the red subpixel 01, green subpixel 02, and blue subpixel 03 to the center of the subpixel is not equal to the distance from the intersection of the extension lines of the two diagonal sides to the center of the subpixel, thereby adjusting the actual brightness center in each virtual pixel unit and making the distribution of each actual brightness center across the entire display panel more uniform.

[0080] In some embodiments, when the first corner of the blue subpixel 03 is chamfered and planarized, the distance from the vertex of the first corner of the blue subpixel 03 to the boundary of the light-emitting layer is not equal to the distance from the vertices of the other vertices to the boundary of the light-emitting layer. For example, the distance from the vertex of the first corner of the blue subpixel 03 to the boundary is constant, and the distance from the other vertices to the boundary of the pixel is approximately zero. That is, the distance from the vertex of the first corner of the blue subpixel 03 to the boundary is greater than the distance from the vertices of the other vertices to the boundary of the blue subpixel 03.

[0081] Continuing with reference to FIG. 4 , the light-emitting layers located in the pixel definition layer define subpixel effective light-emitting areas, and the effective light-emitting areas for the red subpixel 01, green subpixel 02, and blue subpixel 03 are the first effective light-emitting area, the second effective light-emitting area, and the third effective light-emitting area, respectively. In some embodiments, each first effective light-emitting area is defined by a light-emitting layer in the corresponding red subpixel 01, located between opposing anodes and cathodes in a direction perpendicular to the base substrate, and driving light emission. For example, each second effective light-emitting area is defined by a light-emitting layer in the corresponding green subpixel 2, located between opposing anodes and cathodes in a direction perpendicular to the base substrate, and driving light emission. In some embodiments, each effective light-emitting area is defined by a corresponding light-emitting layer and an electrode (anode or cathode) or portion of an electrode that transports carriers (holes or electrons) through the corresponding light-emitting layer. In some embodiments, each effective light-emitting area is defined by at least a portion of the cathode and at least a portion of the anode that overlap with an orthogonal projection on the base substrate, and the at least a portion of the cathode and at least a portion of the anode do not overlap with an orthogonal projection on the base substrate of a first insulating layer, the first insulating layer being located between the cathode and the anode in a direction perpendicular to the base substrate, for example, the first insulating layer including a pixel defining layer. In some embodiments, each red subpixel 01, each green subpixel 02, and each blue pixel 03 includes a first electrode, a light-emitting layer located on a side of the first electrode away from the base substrate, and a second electrode located on a side of the light-emitting layer away from the first electrode. A second insulating layer may be further provided between the first electrode and the light-emitting layer and / or between the second electrode and the light-emitting layer in a direction perpendicular to the base substrate, wherein a projection of the second insulating layer on the base substrate overlaps a projection of the first electrode or the second electrode on the base substrate, and the second insulating layer may have an opening. The opening in the second insulating layer facing one side of the light-emitting layer may expose at least a portion of the first electrode or the second electrode to contact the light-emitting layer or the functional layer supporting light emission. Each first effective light-emitting area and each second effective light-emitting area are defined by a portion of the first electrode or the second electrode that is in contact with the light-emitting layer or the functional layer supporting light emission.In some embodiments, the second insulating layer includes a pixel defining layer. In some embodiments, the functional layer supporting light emission may be any one or more of a hole injection layer, a hole transport layer, an electron transport layer, a hole barrier layer, an electron barrier layer, an electron injection layer, a layer supporting light emission, an interface improvement layer, an anti-reflection layer, etc. In some embodiments, the first electrode may be an anode, and the second electrode may be a cathode. In some embodiments, the first electrode may include at least two stacked layers of indium tin oxide (ITO) and silver (Ag), for example, a three-layer stack of ITO, Ag, and ITO. In some embodiments, the second electrode may include any one or more of magnesium (Mg), Ag, ITO, and indium zinc oxide (IZO), for example, a mixed layer or alloy layer of Mg and Ag.

[0082] Each sub-pixel includes a light-emitting layer, with each red sub-pixel 01 including a first color light-emitting layer located within the aperture and in the pixel-defining layer, and each green sub-pixel 02 including a second color light-emitting layer located within the aperture and in the pixel-defining layer.

[0083] For example, the arrangement of the four green subpixels 02 surrounding one red subpixel 01 may be the same as that within the display area, and the arrangement at the edge of the display area may be different from that within the display area. For example, if the red subpixel 01 is a subpixel in the first row or column, or a subpixel in the last row or column, at the edge of the display area, only two green subpixels 02 may surround the red subpixel 01. For example, the edge of the display area may be rounded, or the shape of the display area may be an irregular display area, such as a circular display area, or a rectangular display area with a hole near one edge. At the edge of the display area, the red subpixel 01 may be surrounded by one, two, or three green subpixels 02.

[0084] In some embodiments, the shapes of the red subpixel 101, the green subpixel 102, and the blue subpixel 103 may be identical or substantially identical. The emissive layers are located within the pixel defining layer to define the effective emissive area of ​​the subpixel. In an embodiment of the present invention, if the first corner of the blue subpixel 03 is chamfered and planarized, the distance from the vertex of the first corner of the blue subpixel 03 to the boundary of the emissive layer is not equal to the distance from the vertices of the other corners to the boundary of the emissive layer. For example, the distance from the vertex of the first corner of the blue subpixel 03 to the boundary of the emissive layer is greater than the distance from the vertices of the other corners to the boundary of the emissive layer.

[0085] In some embodiments, the closest distances from the center of a green subpixel 02 to the boundaries of the light-emitting areas of two directly adjacent red subpixels 01 in the first virtual square 10 are equal. Also, the closest distances from the center of a green subpixel 02 to the boundaries of the light-emitting areas of two directly adjacent blue subpixels 03 are equal. The ratio of the closest distance from the center of a green subpixel 02 to the boundaries of the light-emitting areas of its directly adjacent red subpixel 01 to the closest distance to the boundaries of the light-emitting areas of its directly adjacent blue subpixel 03 is approximately 0.8 to 1.2.

[0086] Specifically, FIG. 5 is a schematic diagram illustrating the distribution of actual luminance centers during display in a pixel array in which the first corners of the blue subpixels 03 in an embodiment of the present invention are chamfered and nearly right-angled. Taking the example of a pixel array in which the first corners of all blue subpixels face right as shown in FIG. 5, the dashed corner at the first corner of the blue subpixel 03 in FIG. 5 represents a pixel array in the related art in which the first corners of the blue subpixels 03 are nearly right-angled. An "x" represents the actual luminance center during display in the pixel array in the related art, and a "·" represents the actual luminance center during display in the pixel array in an embodiment of the present invention. It can be seen from FIG. 5 that when the first corners of the blue subpixels are chamfered, the distribution of the actual luminance centers becomes more uniform.

[0087] In some embodiments, the range of each interior angle of the first imaginary quadrangle 10 is approximately 70° to 110°, and the closer the value of each interior angle is to 90°, the more preferable. However, the range of each interior angle of the first imaginary quadrangle 10 from 70° to 110° does not limit the embodiments of the present invention, and it is sufficient if all of the interior angles of the first imaginary quadrangle 10 are not equal to 90°.

[0088] In some embodiments, the first imaginary quadrilateral 10 may be, but is not limited to, a virtual parallelepiped or a virtual trapezoid, for example, a rhombus, an isosceles trapezoid, or a right-angled trapezoid.

[0089] In some embodiments, FIG. 6 is a schematic diagram of a blue subpixel according to an embodiment of the present invention. As shown in FIG. 6, the first corner of the blue subpixel 03 is chamfered or planarized. The distance from the intersection of the two extended lines 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, where d1:d2 is approximately 1 / 5 to 1 / 2. The vertex of the first corner of the blue subpixel 03 is the point closest to the intersection of the two extended lines of the corresponding vertex angle to the boundary of the subpixel. Similarly, when the first corners of the red subpixel 01 and the green subpixel 02 are chamfered or planarized, the distance from the intersection of the two extended lines of the first corner to the vertex of the first corner and the distance from the vertex of the first corner to the vertex of the second corner may also be set according to the above dimensions.

[0090] In some embodiments, the angles of the virtual vertex angles formed by the intersection of the extension lines of two sides of the corresponding vertex angles of the second corner, the third corner, and the fourth corner of the blue subpixel 03 are approximately equal, or the angles of the virtual vertex angles formed by the intersection of the extension lines of two sides of the corresponding vertex angles of the second corner, the third corner, and the fourth corner of the blue subpixel 03 are approximately 90°, for example, approximately 80° to 100°.

[0091] In some embodiments, the area surrounded by the extensions of two sides of the apex angle of the first corner of the blue subpixel 03 and the outline of the first corner is a first hollowed-out area, and the area surrounded by the extensions of two sides of the apex angle of the second corner of the blue subpixel 03 and the outline of the boundary of the second corner is a second hollowed-out area. The area of ​​the first hollowed-out area is larger than the area of ​​the second hollowed-out area.

[0092] The area surrounded by the extensions of two sides of the apex angle of the third corner of the blue subpixel 03 and the outline of the boundary of the third corner is a third cutout area, and the area surrounded by the extensions of two sides of the apex angle of the fourth corner of the blue subpixel 03 and the outline of the boundary of the fourth corner is a fourth cutout area. In some embodiments, the areas of the second cutout area, the third cutout area, and the fourth cutout area are approximately equal. For example, the areas of the second cutout area, the third cutout area, and the fourth cutout area are all 4 μm 2 The area of ​​the first hollowed-out area is 2 μm 2 Greater than.

[0093] In some embodiments, Figure 7 is a schematic diagram of a blue subpixel in an embodiment of the present invention. As shown in Figure 7, the first corner of the blue subpixel 03 is chamfered or planarized, and the blue subpixel 03 is divided into two parts with areas S1:S2 by a line passing through the center of the blue subpixel 03 in the row direction, or the blue subpixel 03 is divided into two parts with areas S1:S2 by a line passing through the center of the blue subpixel 03 in the column direction, where S1:S2 is approximately 2:8 to 8:2. Similarly, when the first corners of the red subpixel 01 and the green subpixel 02 are chamfered or planarized, lines passing through their centers in the row and column directions also divide their areas in the same proportions as the blue subpixel 03.

[0094] 6, the first corner of the blue subpixel is chamfered or planarized, and the imaginary vertex angle formed by the extensions of the two sides of the first corner is approximately 90°, and in some embodiments, the imaginary vertex angle is approximately 80° to 100°. Similarly, when the first corners of the red subpixel 01 and the green subpixel 02 are chamfered or planarized, the magnitude of the included angle between the extensions of the two sides of each first corner may be approximately the same as the included angle between the extensions of the two sides of the first corner of the blue subpixel 03.

[0095] In some embodiments, the diagonal lines of the red subpixels 01 and blue subpixels 03 in the same row are generally collinear or form an angle of about 30° with the row direction. In some embodiments, Fig. 8 is a schematic diagram of adjacent red and blue subpixels in the same row according to an embodiment of the present invention. As shown in Fig. 8, in a first pixel row 1, that is, in the case of adjacent red and blue subpixels 01 and 03 in the same row, an extension line connecting the farthest end points from the center of each of the first subpixels 01 and 03 on the first side (left side) in the column direction intersects with an extension line connecting the farthest end points from the center of each of the opposing second subpixels (right side), forming an angle of less than 30°.

[0096] 9 is a schematic diagram of one adjacent red subpixel and one adjacent blue subpixel in the same row according to some embodiments of the present invention. As shown in FIG. 9, one adjacent red subpixel 01 and one adjacent blue subpixel 03 in the same column are arranged such that an extension line connecting the farthest end points from the center of each of the first sides (upper sides) in the row direction intersects with an extension line connecting the farthest end points from the center of each of the opposing second sides (lower sides), forming an angle of less than 30°.

[0097] In some embodiments, at least one corner of one adjacent red subpixel 01 and at least one corner of one adjacent blue subpixel 03 in the same row faces each other, and the intersection of extended lines of two sides of the at least one corner of the red subpixel 01 and the intersection of extended lines of two sides of the at least one corner of the blue subpixel 03 are located on a line parallel to the row direction, and / or at least one corner of one adjacent red subpixel 01 and at least one corner of one adjacent blue subpixel 03 in the same column faces each other, and the intersection of extended lines of two sides of the at least one corner of the red subpixel 01 and the intersection of extended lines of two sides of the at least one corner of the blue subpixel 03 are located on a line parallel to the column direction. In some embodiments, the four first virtual rectangles 10 arranged in an array constitute one second virtual polygon. For example, as shown in FIG. 10 , the second virtual polygon formed by four first virtual squares 10 arranged in an array has a quadrilateral structure, and the quadrilateral is, for example, a rectangle (including a square). Of course, the second virtual polygon is not limited to a quadrilateral, and may be a polygon with more sides, such as a hexagon. In the embodiment of the present invention, a case in which the second virtual polygon is a quadrilateral will be described as an example, and will hereinafter be referred to as a second virtual square 100. The four green sub-pixels 02 in the second virtual square 100 are arranged in an "X" shape. In other words, the green sub-pixels 02 located in the same row of the second virtual square 100 are arranged symmetrically in the column direction, and the green sub-pixels 02 in the same column are arranged symmetrically in the row direction. In some embodiments, the red subpixels 01 in the second virtual square 100 are located at the center and vertex of the second virtual square 100, and the blue subpixels 03 are located on the sides of the second virtual square 100, and further, the red subpixels 01 and blue subpixels 03 located on the vertex and sides of the second virtual square 100 are alternately distributed clockwise at the sides and vertex of the second virtual square 100.

[0098] In some embodiments, within the second virtual rectangle 100, the centers of the blue subpixels 03 located in the same row are approximately aligned on a straight line parallel to the row direction, and / or the centers of the blue subpixels 03 located in the same column are approximately aligned on a straight line parallel to the row direction.

[0099] In some embodiments, within the second virtual rectangle 100, the centers of the green subpixels 02 located in the same row are approximately aligned on a straight line parallel to the row direction, and / or the centers of the green subpixels 03 located in the same column are approximately aligned on a straight line parallel to the row direction.

[0100] In some embodiments, the shape of each red subpixel 01 in the pixel array is the same, the shape of each green subpixel 02 is the same, and the shape of each blue subpixel 03 is the same. Of course, some color subpixels may have different shape structures, and the different shape structures may be uniformly distributed among the color subpixels, for example, the shape of the red subpixel 01 may be the same in every other row or every other column.

[0101] In some embodiments, if the first corners of the blue subpixels 03 are chamfered or planarized, the orientation of the first corners of each blue subpixel 03 in the pixel array may be the same or some of them may be the same, for example, the first corners of blue subpixels 03 located in the same row may be the same orientation, and the first corners of blue subpixels 03 located in the same column may be different orientations. Similarly, if the first corners of the green subpixels 02 and red subpixels 01 are chamfered or planarized, they may be arranged in the same orientation as the first corners of the blue subpixels 03.

[0102] An embodiment of the present invention further provides a pixel array substantially identical to the pixel array described above. The pixel array includes a plurality of subpixels, including red subpixels 01, green subpixels 02, and blue subpixels 03, where the red subpixels 01 and blue subpixels 03 are alternately arranged along the row direction to form a plurality of first pixel rows 1, the red subpixels 01 and blue subpixels 03 located in the same column in the plurality of first pixel rows 1 are alternately arranged, and the green subpixels 02 are juxtaposed along the row direction to form a plurality of second pixel rows 2. The centers of two red subpixels 01 and two blue subpixels arranged in the array are connected in order to form first virtual rectangles 10, and one green subpixel is provided within each first virtual rectangle 10. At least some of the interior angles of the first virtual rectangles 10 are not equal to 90°. The red subpixel 01, the green subpixel 02, and the blue subpixel 03 each have a polygonal shape. In at least one of the red subpixel 01, the green subpixel 02, and the blue subpixel 03, the closest distance from the intersection of two extended lines of at least one vertex angle to the boundary of the subpixel is not equal to the closest distance from the intersection of two extended lines of another vertex angle to the boundary of the subpixel. For example, referring to FIG. 6 , the first corner of the blue subpixel 03 is chamfered or planarized. The distance from the intersection of the two extended lines 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, where d1:d2 is approximately 1 / 5 to 1 / 2. The vertex of the first corner of the blue subpixel 03 is the closest point from the intersection of the two extended lines of the corresponding vertex angle to the boundary of the subpixel.

[0103] In some embodiments, the red subpixels 01 have an axially symmetric shape, where all the red subpixels 01 have the same shape but the symmetry axes of at least some of the red subpixels 01 are in different directions; the green subpixels 02 have an axially symmetric shape, where all the green subpixels 02 have the same shape but the symmetry axes of at least some of the green subpixels 02 are in different directions; or the blue subpixels 03 have an axially symmetric shape, where all the blue subpixels 03 have the same shape but the symmetry axes of at least some of the blue subpixels 03 are in different directions. For example, the first corners of the blue subpixels 03 are chamfered or planarized, and all the blue subpixels 03 in the pixel array have the same shape but the orientations of the first corners are different. A portion of the first corner faces upward and a portion of the first corner faces left, and the symmetry axis of the blue subpixel 03 whose first corner faces upward is parallel to the column direction, whereas the symmetry axis of the blue subpixel 03 whose first corner faces left is parallel to the row direction, i.e., the symmetry axes of the blue subpixels 03 whose first corner faces upward and left are in the same direction.

[0104] In some embodiments, the red subpixel 01 and the blue subpixel 03 are axially symmetric, and at least some of the symmetry axes of the red subpixel 01 and the blue subpixel 03 are not aligned. For example, the first corners of the red subpixel 01 and the blue subpixel 03 are both chamfered or planarized, with a portion of the first corner of the red subpixel 01 facing upward and its symmetry axis parallel to the column direction, and a portion of the first corner of the blue subpixel 03 facing left and its symmetry axis parallel to the row direction. In other words, the red subpixel 01 and the blue subpixel 03, whose first corners are oriented differently, have symmetry axes that are not aligned in the same direction.

[0105] In some embodiments, the shape of the green sub-pixel 02 may be an asymmetric shape, such as a right-angled trapezoid.

[0106] In some embodiments, the shape of at least one of the red subpixel 01 and the blue subpixel 03 includes only one axis of symmetry. For example, the first corner of the shape of at least one of the red subpixel 01 and the blue subpixel 03 is chamfered or planarized, and the second, third, and fourth corners of the shape of the red subpixel 01 and the blue subpixel 03 are substantially identical. In this case, the shape of at least one of the red subpixel 01 and the blue subpixel 03 includes only one axis of symmetry.

[0107] In some embodiments, at least two of the number of axes of symmetry of the red subpixel 01, the green subpixel 02, and the blue subpixel 03 are different. For example, one of the red subpixel 01, the green subpixel 02, and the blue subpixel 03 may be axially symmetric and the other two may not be axially symmetric; two of the red subpixel 01, the green subpixel 02, and the blue subpixel 03 may be axially symmetric and the third may not be axially symmetric; or all three may be axially symmetric but have different numbers of axes of symmetry, e.g., one, two, or four, respectively; or all three may be axially symmetric but one may have a different number of axes of symmetry from the other two, e.g., two may have one axis of symmetry and the other may have two or four axes of symmetry. A pixel array according to an embodiment of the present invention will now be described with reference to specific examples.

[0108] In a first example, Fig. 10 is a schematic diagram of the distribution of each sub-pixel in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 4. Fig. 10 merely illustrates an example of the arrangement structure of the sub-pixels in four second virtual rectangles 100. As shown in Figs. 4 and 7, each second virtual rectangle 100 includes four first virtual rectangles 10, and adjacent first virtual rectangles 10 share a side, and adjacent second virtual rectangles 100 share a side. Each first virtual square 10 is formed by connecting the centers of two red subpixels 01 and two blue subpixels 03 arranged in an array, in order, i.e., two red subpixels 01 and two blue subpixels 03 are provided at the positions of the four vertices of each first virtual square 10, with the two red subpixels 01 provided at two opposing vertices of the first virtual square 10 and the two blue subpixels 03 provided at the positions of the other two opposing vertices of the first virtual square 10, and one green subpixel 02 provided at the center of each first virtual square 10.

In each second virtual rectangle 100, two blue subpixels in the same row are arranged symmetrically along the column direction, and two blue subpixels in the same column are arranged symmetrically along the row direction. In two adjacent first pixel rows 1, the first corners of the blue subpixels 03 in one row are oriented in the same direction, while the first corners of the blue subpixels 03 in the other row are oriented in the opposite direction.

The blue subpixels 03 arranged diagonally around each red subpixel 01 are symmetrical with respect to the center of the red subpixel 01.

[0111] 10, if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center is one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction.

[0112] In a second example, FIG. 13 is a schematic diagram of a pixel array according to a second embodiment of the present invention. As shown in FIG. 13, the position and shape of each subpixel in this pixel array are all identical to the position and shape of each subpixel in the pixel array of the first example, with the only difference being that the orientation of the first corners of some blue subpixels 03 is different. In this pixel array, the orientation of the first corners of all blue subpixels 03 located in the same row is the same, and the orientation of the first corners of all blue subpixels 03 located in the same column is also the same. For example, in FIG. 13, the first corners of all blue subpixels 03 located in the first row face upward, and the first corners of all blue subpixels 03 located in the first column face left.

[0113] Fig. 10 is a schematic diagram of the distribution of each subpixel in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 13. As shown in Fig. 10, the first first virtual rectangle 10 in the upper left corner of the second virtual rectangle 100 has one diagonal angle equal to 92° (shown as 92°) and another angle of 90°, and the other first virtual rectangles 10 have at least one angle of 90°, with the vertex of the 90° angle located at the center of a red subpixel. The blue subpixels 03 at the two diagonal positions of each first virtual subsquare are arranged symmetrically with respect to the line connecting the centers of the two red subpixels 01.

[0114] 10 , if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center position being one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction.

In a third example, FIG. 13 is a schematic diagram of a pixel array according to a third embodiment of the present invention. As shown in Figure 13, the position and shape of each subpixel in this pixel array are the same as those in the pixel arrays of the two previous examples, with the only difference being that the orientation of the first corners of some of the blue subpixels 03 is different. In this pixel array, the orientation of the first corners of all the blue subpixels 03 is the same. For example, the first corners of all the blue subpixels 03 in Figure 13 face left.

[0115] Fig. 14 is a schematic diagram showing the distribution of sub-pixels in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 13. As shown in Fig. 14, the first first virtual rectangle 10 in the upper left corner of the second virtual rectangle 100 is an isosceles trapezoid with two angles of 92° and two angles of 88°.

[0116] 14, if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center is one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction. Also, as shown in FIG. 14, the vertical distances from the center of the green subpixel 02 in each first virtual rectangle 10 to the boundaries of the light-emitting areas of the red subpixels 01 and blue subpixels 03 are a and b, respectively, where a=b.

[0117] In the fourth example, FIG. 15 is a schematic diagram of a pixel array according to a fourth embodiment of the present invention. As shown in FIG. 15, the position and shape of each subpixel in this pixel array are all identical to the position and shape of each subpixel in the pixel arrays of the three examples described above, with the only difference being that the orientation of the first corners of some blue subpixels 03 is different. In this pixel array, the orientation of the first corners of all blue subpixels 03 in the same row is the same, but the orientation of the first corners of the blue subpixels 03 in the first pixel row 1, which is an odd row, is opposite to that of the first corners of the blue subpixels 03 in the first pixel row 1, which is an even row. For example, the first corners of all blue subpixels 03 in the first first pixel row 1 face right, and the first corners of all blue subpixels 03 in the second first pixel row 1 face left.

[0118] Fig. 16 is a schematic diagram of the distribution of each sub-pixel in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 15. As shown in Fig. 16, the first first virtual rectangle 10 in the upper left corner of the second virtual rectangle 100 has a diagonal angle of 92° and another diagonal angle of 88°.

[0119] 16, if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center is one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction. Also, as shown in Fig. 16, the vertical distances from the center of the green subpixel 02 in each first virtual rectangle 10 to the boundaries of the light-emitting areas of the red subpixels 01 and blue subpixels 03 are a and b, respectively, where a = b.

[0120] In the fifth example, FIG. 17 is a schematic diagram of a pixel array according to the fifth embodiment of the present invention. As shown in FIG. 17, the position and shape of each subpixel in this pixel array are all identical to the position and shape of each subpixel in the pixel arrays of the four examples described above, with the only difference being that the orientation of the first corners of some blue subpixels 03 is different. In this pixel array, the orientation of the first corners of all blue subpixels 03 located in the same row is the same, and the orientation of the first corners of all blue subpixels 03 located in the same column is also the same. For example, in FIG. 17, the first corners of all blue subpixels 03 located in the first row face upward, and the first corners of all blue subpixels 03 located in the first column face left.

[0121] Fig. 18 is a schematic diagram of the distribution of each sub-pixel in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 17. As shown in Fig. 18, the first first virtual rectangle 10 in the upper left corner of the second virtual rectangle 100 has two diagonal angles that are equal and 90°, and the other diagonal angles are 92° and 88°, respectively.

[0122] 18, if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center position being one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction. Also, as shown in Fig. 18, the vertical distances from the center of the green subpixel 02 in each first virtual rectangle 10 to the boundaries of the light-emitting areas of the red subpixels 01 and blue subpixels 03 are a and b, respectively, where a = b.

[0123] Note that the above examples do not limit the arrangement of each blue subpixel 03 in the embodiments of the present invention, and any pixel array formed by rotating any one blue subpixel 03 by any angle with respect to the midpoint of the line connecting the centers of adjacent red subpixels 01 along the row direction is within the scope of protection of the embodiments of the present invention.

[0124] In some embodiments, when only the first corner of the blue subpixel 03 is chamfered or planarized and both first corners face upward, a line connecting the vertices of two diagonal corners (third and fourth corners) of the red subpixel 01 and the blue subpixel 03 located in the same row is approximately collinear, and a line connecting the vertices of the first and second corners of the red subpixel 01 and the second corner of the blue subpixel 03 located in the same column is approximately collinear.

[0125] In all of the above first to fifth examples, the first corners of the blue subpixels 03 have been described as being chamfered. In some embodiments, FIG. 19 is a schematic diagram of a pixel array in which the first corners of the blue subpixels 03 are chamfered according to an embodiment of the present invention. As shown in FIG. 19 , the position, shape, and arrangement of each subpixel in such a pixel array are the same as those of the subpixels in the pixel array of the fourth example described above. In such a pixel array, the first corners of the blue subpixels 03 located in the same row all face the same direction, while the first corners of the blue subpixels 03 located in the odd-numbered first pixel row 1 face opposite directions to those of the blue subpixels 03 located in the even-numbered first pixel row 1. For example, the first corners of the blue subpixels 03 in the first first pixel row 1 all face right, and the first corners of the blue subpixels 03 in the second first pixel row 1 all face left.

[0126] Fig. 20 is a schematic diagram of the distribution of each sub-pixel in the first second virtual rectangle in the upper left corner of the pixel array shown in Fig. 19. As shown in Fig. 20, the first first virtual rectangle 10 in the upper left corner of the second virtual rectangle 100 has a diagonal angle of 91° and another diagonal angle of 89°.

[0127] 20, if the line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 located in the same column is L, the second virtual rectangle 100 is a square with a side length of 2L, its center is one red subpixel 01, and the center of the green subpixel 02 in each first virtual rectangle 10 is located on the center line connecting the centers of adjacent red subpixels 01 and blue subpixels 03 in the row or column direction. Also, as shown in Fig. 20, the vertical distances from the center of the green subpixel 02 in each first virtual rectangle 10 to the boundaries of the light-emitting areas of the red subpixels 01 and blue subpixels 03 are a and b, respectively, where a = b.

[0128] In addition, in all of the above examples, the first corner of the blue subpixel 03 is different from the other three corners; that is, the distance from the vertex of the first corner of the blue subpixel 03 to the center of the subpixel is smaller than the distance from each of the vertices of the other three corners to the center of the subpixel. In some embodiments, the shape of the first corner of at least one of the red subpixel 01 and the green subpixel 02 may be designed to match the shape of the blue subpixel 03 described above. This will be described below with reference to specific examples.

As shown in FIG. 21, the first corners of all red subpixels 01 in this pixel array face right. Of course, the centers of the red subpixels 01 may be changed by rotating the first corners of the red subpixels 01 so that the first corners face in any direction. After rotating the first corners of the red subpixels 01, the red subpixels 01 may be arranged in the same manner as the blue subpixels 03 described above. FIG. 22 is a schematic diagram of the distribution of actual luminance centers during display in a pixel array in which the first corners of the red subpixels 01 are chamfered to form nearly right angles according to an embodiment of the present invention. Taking the example of a pixel array in which the first corners of all red subpixels in the pixel array face right as shown in FIG. 22, the dashed corner at the position of the first corner of the blue subpixel 03 in FIG. 22 represents a pixel array in the related art in which the first corners of the red subpixels 01 are nearly right angles. The "x" represents the actual luminance center when the pixel array in the related art displays, and the "·" represents the actual luminance center when the pixel array in the embodiment of the present invention displays. It can be seen from Figure 22 that when the first corner of the red sub-pixel is chamfered, the distribution of its actual luminance center becomes more uniform.

[0130] 23 is a schematic diagram of a pixel array in which the first corners of the green subpixels are chamfered according to an embodiment of the present invention. As shown in FIG. 23, the orientations of the first corners of the four green subpixels 02 in each second virtual square 100 in the pixel array are all different, and two green subpixels 02 located in the same column are arranged symmetrically with respect to the row direction. Of course, the centers of the green subpixels 02 may be changed by rotating the first corners of the green subpixels 02 so that the first corners of the green subpixels 02 are oriented in any direction, or after rotating the first corners of the green subpixels 02, they may be arranged in the same manner as the blue subpixels 03 described above.

[0131] FIG. 24 is a schematic diagram of a pixel array in which the first corners of the red and blue subpixels are chamfered according to an embodiment of the present invention. As shown in FIG. 22, the first corners of the red subpixels 01 in the same row are oriented in the same direction, the first corners of the blue subpixels 03 in the same row are oriented in the same direction, and the first corners of the red and blue subpixels 01 and 03 in the same row are oriented in opposite directions. Of course, the centers of the red and blue subpixels 01 and 03 may be changed by rotating the first corners of the red and blue subpixels 01 and 03 so that the first corners of the red and blue subpixels 01 and 03 are oriented in any direction. After rotating the first corners of the red and blue subpixels 01 and 03, they may be arranged in the same manner as the blue subpixel 03 described above.
