[0012] While the present text describes several embodiments, the descriptions are illustrative and not limiting. Many more embodiments and implementations may exist within the scope of the embodiments described herein. While many possible combinations of features are shown in the drawings and discussed in exemplary embodiments, many other combinations of the disclosed features are possible. Unless otherwise limited, any feature or element of any embodiment can be used in combination with or substituted for any other feature or element in any other embodiment.

[0013] In describing exemplary embodiments, the specification may have expressed a method or process as a particular sequence of steps. However, to the extent that the method or process does not depend on the particular order of steps described herein, the method or process should not be limited to a particular order of steps. As one of ordinary skill in the art will understand, other order of steps are possible. Accordingly, the particular order of steps described in the specification should not be construed as a limitation on the claims. Furthermore, claims to the method or process are not limited to performing those steps in the order described; as one of ordinary skill in the art will readily understand, these orders may be changed and still remain within the spirit and scope of the embodiments of the present disclosure.

[0014] In the drawings, the size of components, layer thicknesses, or areas may be exaggerated for clarity. Therefore, one embodiment of the present disclosure is not limited to the size, and the shapes and sizes of parts in the drawings do not reflect actual proportions. In addition, the drawings are schematic illustrations of ideal examples, and one embodiment of the present disclosure is not limited to the shapes, numerical values, etc. shown in the drawings.

[0015] In this specification, ordinal numbers such as "first," "second," and "third" are used to avoid confusion of components and are not intended to limit the number of components.

[0016] For convenience, the positions of components are described herein with reference to the drawings using terms indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer." However, this is intended to simplify and explain the present specification, and is not intended to indicate or suggest that the described devices or elements have a specific orientation or are constructed and operated in a specific orientation. Therefore, it is not intended to limit the present disclosure. The positional relationships of components are appropriately changed depending on the direction in which the components are described. Therefore, the terms are not limited to those described in the specification, and may be appropriately changed in some cases.

[0017] In this specification, unless otherwise clearly specified and limited, the terms "attach," "couple," and "connect" should be understood in a broad sense. For example, they may be fixedly connected, detachably connected, or integrally connected. They may be mechanically connected or electrically connected. They may be directly connected, indirectly connected via a linker, or internally connected between two elements. Those skilled in the art can understand the meaning of the above terms in the present disclosure depending on the specific circumstances.

[0018] In this specification, "electrical connection" includes cases where components are connected via an element having a certain electrical function. The "element having a certain electrical function" is not particularly limited as long as it can transmit and receive electrical signals between the connected components. The "element having a certain electrical function" may be, for example, an electrode or wiring, a switching element such as a transistor, or other functional element such as a resistor, inductor, or capacitor.

[0019] In this specification, a transistor refers to an element that includes at least three terminals: a gate electrode, a drain electrode, and a source electrode. A transistor has a channel region between a drain electrode (also referred to as a drain electrode terminal or a drain region) and a source electrode (also referred to as a source electrode terminal or a source region), and current can flow through the drain electrode, the channel region, and the source electrode. In this specification, a channel region refers to a region through which current mainly flows. In this specification, the functions of a "source electrode" and a "drain electrode" may be interchanged when using transistors with opposite polarity or when the current direction changes during operation in a circuit. Therefore, in this specification, the terms "source electrode" and "drain electrode" may be interchanged.

[0020] As used in the examples of this disclosure, "about" and "similar" refer to values ​​that do not precisely define boundaries but allow for process and measurement error.

[0021] The term "side by side" used in the embodiments of the present disclosure refers to being arranged in a single line (row or column), regardless of whether they are front to back.

[0022] FIG. 1 is a structural schematic diagram of an OLED display device. As shown in FIG. 1, in a direction perpendicular to the OLED display device, the OLED display device may include a base substrate 10, a pixel driving circuit 11 disposed on the base substrate 10, and a pixel structure disposed on the side of the pixel driving circuit 11 away from the base substrate 10. For example, the pixel driving circuit 11 may include multiple pixel circuits, each configured to drive multiple light-emitting elements 12 in a pixel structure to be subsequently formed. The circuit structure and layout of the pixel circuits may be designed according to actual circumstances, and the embodiments of the present disclosure do not limit this. For clarity and simplicity, FIG. 1 schematically illustrates only one transistor T1 in each pixel circuit of the pixel driving circuit 11, and the transistor T1 is arranged to couple with the light-emitting element 12 to be subsequently formed. For example, the pixel driving circuit 11 may further include various wirings, such as scanning signal lines and data signal lines, and the embodiments of the present disclosure do not limit this. For example, the base substrate 10 may be, but is not limited to, a silicon-based substrate, such as a single-crystal silicon-based substrate.

[0023] 1, taking transistor T1 as an example, the transistor T1 in the pixel driving circuit 11 may include a gate electrode G, a source electrode S, and a drain electrode D. For example, the three electrodes are electrically connected to three electrode connection parts, for example, via vias filled with tungsten metal (i.e., tungsten vias, W-vias). Furthermore, the three electrodes may be electrically connected to other electrical structures (e.g., transistors, wiring, light-emitting elements, etc.) via the corresponding electrode connection parts.

[0024] In an exemplary embodiment, as shown in FIG. 1 , the OLED display device may include a plurality of light-emitting elements 12 formed on a pixel driving circuit 11 in a direction perpendicular to the OLED display device. For example, the light-emitting element 12 may include a first electrode 121 (e.g., an anode), an organic light-emitting functional layer 122, and a second electrode 123 (e.g., a cathode), which are sequentially stacked. For example, the first electrode 121 may be electrically connected to the source electrode S of the corresponding transistor T1 through a tungsten via (through a connection portion corresponding to the source electrode S). Here, the positions of the source electrode S and the drain electrode D may be interchanged, i.e., the first electrode 121 may be electrically connected to the drain electrode D. For example, the organic light-emitting functional layer 122 may include an EL (emitted-light) layer and may further include one or more of an electron injection layer, an electron transport layer, a hole injection layer, and a hole transport layer. For example, the second electrode 123 may be a transparent electrode. For example, the second electrode 123 may be a common electrode, ie, multiple light emitting elements 12 in a pixel structure may share the entire second electrode 123 .

[0025] In an exemplary embodiment, as shown in FIG. 1 , the OLED display device may further include a first encapsulation layer 13, a color filter layer 15, and a second encapsulation layer 14, which are sequentially disposed on the plurality of light-emitting elements 12 in a direction perpendicular to the OLED display device. For example, the color filter layer 15 may include a plurality of color filters (CF) 151 and a black matrix (BM) 152 disposed between adjacent color filters 151. The plurality of color filters 151 correspond to the plurality of light-emitting elements in the pixel structure and are configured to transmit light from the light-emitting elements. One color filter 151 and a corresponding light-emitting element are defined as one sub-pixel. For example, the color filter 151 may include a red (R) color filter unit, a green (G) color filter unit, and a blue (B) color filter unit. The red (R) color filter unit, the green (G) color filter unit, and the blue (B) color filter unit may correspond to the red (R) sub-pixel, the green (G) sub-pixel, and the blue (B) sub-pixel, respectively. For example, but not limited to, the material of color filter 151 may be color photoresist. For example, but not limited to, first encapsulation layer 13 and second encapsulation layer 14 may be one or more of a polymer and a ceramic Thin Film Encapsulation (TFE) layer.

[0026] In an exemplary embodiment, the OLED display device may further include a cover plate 16 on the side of second encapsulation layer 14 away from base substrate 10. For example, but not limited to, cover plate 16 may be a glass cover plate.

[0027] In an exemplary embodiment, the first encapsulation layer 13 and the second encapsulation layer 14 are TFE layers, for example, because the OLED material and the cathode (typically Mg / Ag) material are sensitive (i.e., easily oxidized) by water (H2O) and oxygen gas (O2), and therefore the TFE layer can protect the OLED display device. In this way, the thin film encapsulation technology can be used to isolate the OLED display device from water and oxygen, thereby achieving a protective effect.

[0028] On the other hand, as shown in FIG. 1, some OLED display devices (e.g., Micro OLED display devices) typically employ a white-light-emitting layer and CF151 to achieve color display. CF151 absorbs light of a specific wavelength to achieve "monochromatic light" transmission (e.g., monochromatic red, blue, or green light). Therefore, the brightness of white light from the white-light-emitting layer in an OLED display device is significantly reduced after passing through CF151. The transmittance of low-temperature CF151 used in some conventional OLED display devices (e.g., Micro OLED display devices) is approximately 18% to 30%, and the aperture ratio (AR) of the anode in the active area (AA) is approximately 60% to 70%. Therefore, as calculated using the following equation (1), only about ¼ of the white light from the emitting layer in some conventional OLED display devices (e.g., Micro OLED display devices) is effectively utilized. Therefore, the low transmittance of CF151 is one of the factors that contribute to the relatively low luminance and relatively high power consumption of some OLED display devices (eg, Micro OLED display devices).

[0029]

number

[0030] In equation (1), τ is the transmittance of the CF in the OLED display device, α is the aperture ratio of the AA area in the OLED display device, L is the luminance of white light from the OLED display device, and L CFindicates the brightness that can be perceived by the human eye after white light from an OLED display device passes through CF.

[0031] On the other hand, the pixel arrangement of some OLED display devices (e.g., Micro OLED display devices) adopts a pixel structure design in which one pixel is composed of three sub-pixels of RGB (Red, Green, Blue) colors, as shown in Figure 2A. Here, depending on whether sub-pixel rendering is adopted, there are two types of pixel arrangements: BV3 arrangement and Delta RGB arrangement. However, these two types of pixel arrangements cause problems with high power consumption and low luminance in most OLED display devices, and also cause cross-color problems when the viewing angle is relatively large, as shown in Figure 2B.

[0032] On the other hand, in some OLED display devices (e.g., Micro OLED display devices), due to issues with the BM material, the RGB cross-color problem is not prevented by introducing a BM, but rather by overlaying CF (e.g., RGB color photoresist) between the BM and CF. However, when the viewing angle is relatively large, the CF overlay between RGB has almost no effect in preventing cross-color. Therefore, some OLED display devices (e.g., Micro OLED display devices) have a serious problem of large-viewing-angle cross-color. Furthermore, the introduction of a BM or CF overlay results in a reduction in the aperture ratio, exacerbating the problem of relatively low emission brightness in some OLED display devices.

[0033] An embodiment of the present disclosure provides a pixel structure, which may include multiple pixel rows and multiple pixel columns. Each pixel row may include subpixels of four different colors. The multiple pixel columns may include multiple first pixel columns and multiple second pixel columns arranged alternately. Each first pixel column may include subpixels of three of the four different colors. Each second pixel column may include subpixels of a color other than the three of the four different colors. Thus, according to the pixel structure of the embodiment of the present disclosure, by introducing one second pixel column, which includes only subpixels of colors other than the three colors, between two first pixel columns, each including subpixels of three colors, the subpixels of colors other than the three colors can be introduced between the two first pixel columns, thereby isolating the subpixels of the colors other than the three colors. This allows for uniform mixing of the four different colors, improving the color mixing effect and luminance. Furthermore, when the viewing angle is shifted in the first direction (i.e., the pixel direction), since both sides of the three-color subpixel are subpixels of colors other than the three colors, the light from the three-color subpixel at a large angle only enters the subpixels of colors other than the three colors, and does not enter the three-color subpixel. This avoids serious cross-color problems, and further avoids the need for a black matrix or carbon fiber overlay, which reduces the aperture ratio, improves the luminance of the device, and improves the transmittance and light efficiency of the device. Furthermore, it also improves the quality of the display screen.

[0034] The embodiments of the present disclosure further provide a pixel structure, which may include a plurality of pixels arranged in an array. Each pixel may include four subpixels of different colors. The ratio of the number of subpixels of the four different colors in each pixel may be 1:1:1:3. Thus, the pixel structure according to the embodiments of the present disclosure allows the four subpixels of different colors to be grouped into one pixel, thereby improving the brightness of each pixel, achieving a uniform mixture of the four different colors, improving the color mixing effect, improving the luminance, and improving the display quality. Here, if the total number of subpixels in the pixel structure is not an integer multiple of six, the phrase "the ratio of the number of subpixels of the four different colors in each pixel may be 1:1:1:3" in the embodiments of the present disclosure may mean that the ratio of the number of subpixels of the four different colors in each pixel is approximately 1:1:1:3. For example, if dummy pixels are present around the AA area of ​​a display device, a situation may arise in which the ratio of the number of subpixels of the four different colors in each pixel does not satisfy the 1:1:1:3 ratio.

[0035] The embodiments of the present disclosure further provide a pixel structure, which may include a plurality of repeat units arranged in an array. Each repeat unit may include three pixels arranged side by side. Each pixel may include sub-pixels of four different colors. The arrangement positions of the sub-pixels of four different colors in the three pixels may be different. Thus, according to the pixel structure of the embodiments of the present disclosure, sub-pixels of four different colors are divided into one pixel, and three pixels with different arrangements of sub-pixels of four different colors are divided into one repeat unit, which can improve the brightness of each pixel, achieve uniform mixing of the four different colors, improve the color mixing effect, improve the light emission brightness, ensure display uniformity, and improve the quality of the display screen.

[0036] In an exemplary embodiment, the four different color subpixels may include a red (R) subpixel, a blue (B) subpixel, a green (G) subpixel, and a white (W) subpixel. Alternatively, the four different color subpixels may include a red (R) subpixel, a blue (B) subpixel, a green (G) subpixel, and a yellow (Y) subpixel. Alternatively, the four different color subpixels may adopt other color combinations. However, the embodiments of the present disclosure are not limited thereto.

[0037] In an exemplary embodiment, the subpixels of colors other than three of the four different colors may include white (W) subpixels, yellow (Y) subpixels, or subpixels of other colors, although the embodiments of the present disclosure are not limited thereto.

[0038] In an exemplary embodiment, for example, the subpixels of four different colors may include a red (R) subpixel, a blue (B) subpixel, a green (G) subpixel, and a white (W) subpixel, and the subpixels of three of the four different colors may include a red (R) subpixel, a blue (B) subpixel, and a green (G) subpixel, and the subpixel of a color other than the three of the four different colors may be a white (W) subpixel.

[0039] 3 is a structural schematic diagram of a pixel structure in an exemplary embodiment of the present disclosure, and FIG. 4 is another structural schematic diagram of a pixel structure in an exemplary embodiment of the present disclosure. In FIG. 3 and FIG. 4, three of the four different color subpixels include a red (R) subpixel, a blue (B) subpixel, and a green (G) subpixel, and the subpixel of a color other than the four different colors is a white (W) subpixel. Nine pixel rows 33 and six alternating first pixel columns 31 and six second pixel columns 32 are shown in the pixel structure, and six repeat units 30 are shown in the pixel structure, each repeat unit 30 including three pixels 34, each pixel 34 including three white (W) subpixels, one red (R) subpixel, one blue (B) subpixel, and one green (G) subpixel. The pixel structure according to the embodiment of the present disclosure includes, but is not limited to, the above-described configurations. For example, the positions of the red (R) subpixel, blue (B) subpixel, and green (G) subpixel in the repeat unit shown in Figures 3 and 4 may be interchanged. For example, the positions of the four different color subpixels in the pixel structures shown in Figures 3 and 4 may be interchanged. For example, the colors of the four different color subpixels in the pixel structures shown in Figures 3 and 4 may be interchanged. Exemplary embodiments of the present disclosure are not limited thereto.

[0040] Hereinafter, the pixel structure in the embodiment of the present disclosure will be described in detail with reference to FIGS.

[0041] 3 and 4, the first pixel column 31 may be composed of an array of red (R), blue (B), and green (G) subpixels, and the second pixel column 32 may be composed of only an array of white (W) subpixels. Thus, in the pixel structure, along the first direction (i.e., the row direction), the white (W) subpixels can separate any two different color subpixels from the red (R), blue (B), and green (G) subpixels (e.g., in pixel row 33, the white (W) subpixels can separate the red (R) and green (G) subpixels, separate the green (G) and blue (B) subpixels, and separate the blue (B) and red (R) subpixels). As a result, when the viewing angle is shifted in the first direction, as shown in Figure 5, the large-angle light from any one of the red (R), blue (B), and green (G) subpixels can only enter the adjacent white (W) subpixel and not the other subpixels, thereby avoiding the cross-color problem, improving the color mixing effect, luminance, and display quality.

[0042] In an exemplary embodiment, each pixel row 33 may be linear, as shown in FIGS.

[0043] In an exemplary embodiment, each pixel row may be zigzag, for example, as shown in Figures 3 and 4, the alternating first pixel column 31 and second pixel column 32 are both zigzag.

[0044] In an exemplary embodiment, the numbers of the three color sub-pixels in each first pixel column are the same, for example, the numbers of red (R), blue (B) and green (G) sub-pixels in the first pixel column 31 are the same, as shown in Figures 3 and 4 .

[0045] In an exemplary embodiment, the total number of sub-pixels in the second pixel column 32 is equal to the total number of sub-pixels in the first pixel column 31, as shown in FIGS.

[0046] In an exemplary embodiment, the ratio of the numbers of subpixels of four different colors in each pixel row may be 1:1:1:3. For example, as shown in FIGS. 3 and 4 , the ratio of the numbers of red (R) subpixels, blue (B) subpixels, green (G) subpixels, and white (W) subpixels in pixel row 33 is 1:1:1:3. Here, if the total number of subpixels in the pixel structure is not an integer multiple of 6, the phrase "the ratio of the numbers of subpixels of four different colors in each pixel row is 1:1:1:3" in the embodiments of the present disclosure may refer to the ratio of the numbers of subpixels of four different colors in each pixel row being close to 1:1:1:3. For example, if dummy pixels are present around the AA area in the display device, a situation may arise in which the ratio of the numbers of subpixels of four different colors in the pixel row may not satisfy this ratio (i.e., 1:1:1:3).

[0047] In an exemplary embodiment, adjacent subpixels in each pixel row have different colors. For example, as shown in FIGS. 3 and 4, a white (W) subpixel can isolate any two subpixels of different colors from the red (R), blue (B), and green (G) subpixels, thereby avoiding the adjacent two subpixels from the red (R), blue (B), and green (G) subpixels. In this way, when the viewing angle shifts in the first direction (the pixel row direction), as shown in FIG. 5, the adjacent subpixels of any one of the red (R), blue (B), and green (G) subpixels are all white (W) subpixels. This allows the large-angle light from the red (R), blue (B), and green (G) subpixels to enter only the adjacent white (W) subpixel, but not the other subpixels. This avoids serious cross-color issues, improves color mixing effects, enhances luminance, and enhances the quality of the display screen.

[0048] 3 and 4, the first pixel column 31 may include one or more of the following arrangements: a red (R) subpixel, a blue (B) subpixel, and a green (G) subpixel that are sequentially alternated; a green (G) subpixel, a red (R) subpixel, and a blue (B) subpixel that are sequentially alternated; and a blue (B) subpixel, a green (G) subpixel, and a red (R) subpixel that are sequentially alternated. For example, as shown in FIGS. 3 and 4, the pixel structure may include the first pixel column 31 in the above three sequentially alternated arrangements, whereby the red (R) subpixel, the blue (B) subpixel, and the green (G) subpixel may be uniformly arranged in one repeat unit 30, thereby improving the light emission brightness of the device, the transmittance and light efficiency of the device, the color mixing effect, and the display quality.

[0049] In an exemplary embodiment, as shown in Figures 3 and 4, adjacent sub-pixels in each first pixel column 31 are of different colors.

[0050] In an exemplary embodiment, the colors of adjacent subpixels in adjacent first pixel columns among the plurality of pixel columns in the pixel structure are different. For example, as shown in Figures 3 and 4, a first first pixel column 31 includes red (R) subpixels, blue (B) subpixels, and green (G) subpixels that are sequentially alternated, and a second first pixel column 31 includes green (G) subpixels, red (R) subpixels, and blue (B) subpixels that are sequentially alternated. Thus, along the first direction, the red (R) subpixels in the first first pixel column 31 are adjacent to the green (G) subpixels in the second first pixel column 31, the blue (B) subpixels in the first first pixel column 31 are adjacent to the red (R) subpixels in the second first pixel column 31, and the green (G) subpixels in the first first pixel column 31 are adjacent to the blue (B) subpixels in the second first pixel column 31.

[0051] In an exemplary embodiment, the shape of each sub-pixel may be a hexagon, and all six interior angles of the hexagon are 120°. In this way, the arrangement between the sub-pixels in the pixel structure can be made strict, which can improve the aperture ratio, increase the light emission brightness, and reduce power consumption.

[0052] In an exemplary embodiment, the shape of each sub-pixel is a hexagon, where three sets of opposite sides of the hexagon are parallel and at least two sets of opposite sides have equal lengths, thereby achieving a strict alignment between the sub-pixels in the pixel structure, thereby improving the aperture ratio, increasing the light emission brightness, and reducing power consumption.

[0053] For example, as shown in FIG. 3, each subpixel may be shaped like a regular hexagon, with three sets of opposite sides parallel to each other and the six sides all having the same length. Alternatively, as shown in FIG. 4, each subpixel may be shaped like a parallel hexagon, with three sets of opposite sides parallel to each other and the lengths of two sets of opposite sides being equal. For example, as shown in FIG. 6, the parallel hexagon may include a first side (side ab), a second side (side bc), a third side (side cd), a fourth side (side de), a fifth side (side ef), and a sixth side (side fa). The first set of opposite sides may include the first side (side ab) and the fourth side (side de), which are parallel to each other; the second set of opposite sides may include the second side (side bc) and the fifth side (side ef), which are parallel to each other; and the third set of opposite sides may include the third side (side cd) and the sixth side (side fa), which are parallel to each other; and the lengths of the first set of opposite sides may be equal to those of the third set of opposite sides. Here, FIG. 6 shows one sub-pixel as an example.

[0054] In an exemplary embodiment, six subpixels are defined as one pixel, and three pixels arranged side by side are defined as one repeat unit. As shown in Figures 3 and 4, the pixel structure may include a plurality of repeat units 30 arranged in an array along a first direction (row direction) and a second direction (column direction). Each row of each repeat unit 30 includes one red (R) subpixel, one blue (B) subpixel, one green (G) subpixel, and three white (W) subpixels. Each repeat unit 30 may include three pixels 34 arranged side by side, and the arrangement of the subpixels of the three pixels 34 in each repeat unit 30 is different. Each pixel 34 may include one red (R), one blue (B), one green (G), and three white (W) subpixels, with the first column of each pixel 34 including one red (R), one blue (B), and one green (G) subpixel arranged in a zigzag pattern, and the second column of each pixel 34 including three white (W) subpixels arranged in a zigzag pattern. Each subpixel is hexagonal, with all six interior angles of the hexagon being 120°.

[0055] In this way, on the one hand, by dividing one red (R) subpixel, one blue (B) subpixel, one green (G) subpixel and three white (W) subpixels into one pixel, the brightness of each pixel can be improved, the colors of the subpixels of multiple colors can be uniformly mixed, and the quality of the display screen can be improved. On the other hand, each row of each repeat unit 30 includes one red (R) subpixel, one blue (B) subpixel, one green (G) subpixel, and three white (W) subpixels, and the arrangement of the subpixels of the three pixels 34 in each repeat unit 30 is different, and each pixel 34 may include one red (R) subpixel, one blue (B) subpixel, one green (G) subpixel, and three white (W) subpixels, where the first column of each pixel 34 includes one red (R) subpixel, one blue (B) subpixel, and one green (G) subpixel arranged in a zigzag pattern, and the second column of each pixel 34 includes three white (W) subpixels arranged in a zigzag pattern, thereby improving the brightness of each repeat unit, achieving uniform color mixing of the multiple color subpixels, and improving the quality of the display screen. On the other hand, since each subpixel has a hexagonal shape and all six interior angles of the hexagon are 120°, the arrangement between the subpixels in the pixel structure can be strict, improving the aperture ratio, increasing the luminance, and reducing power consumption. When the pixel structure according to the exemplary embodiment of the present disclosure is applied to a display product, the luminance of the display product can be improved and the power consumption of the display product can be reduced. This allows for a wider dynamic display range. Furthermore, the pixel structure according to the exemplary embodiment of the present disclosure can be applied to fields such as head-up displays (HUDs), transparent displays, augmented reality (AR) displays, and virtual reality (VR) displays. Compared to the pixel structure shown in FIG. 2A , the luminance of the pixel structure according to the exemplary embodiment of the present disclosure can be improved by approximately 1.5 to 2 times.

[0056] In an exemplary embodiment, as shown in FIGS. 3 and 4 , each repeat unit 30 may include first, second, and third pixels arranged sequentially along a first direction. The first row of first pixels may include red (R) subpixels and white (W) subpixels arranged sequentially along the first direction. The second row of first pixels may include blue (B) subpixels and white (W) subpixels arranged sequentially along the first direction. The third row of first pixels may include green (G) subpixels and white (W) subpixels arranged sequentially along the first direction. The first row of second pixels may include green (G) subpixels and white (W) subpixels arranged sequentially along the first direction. The second row of second pixels may include red (R) subpixels and white (W) subpixels arranged sequentially along the first direction. The third row of second pixels may include blue (B) subpixels and white (W) subpixels arranged sequentially along the first direction. The first row of the third pixels may include blue (B) subpixels and white (W) subpixels arranged sequentially along the first direction. The second row of the third pixels may include green (G) subpixels and white (W) subpixels arranged sequentially along the first direction. The third row of the third pixels may include red (R) subpixels and white (W) subpixels arranged sequentially along the first direction. In this manner, each row of the repeat unit has the same number of red (R) subpixels, blue (B) subpixels, and green (G) subpixels, and each red (R) subpixel, each blue (B) subpixel, and each green (G) subpixel may be adjacent to a white (W) subpixel. This can improve the luminance of the device, enhance the transmittance and light efficiency of the device, ensure color mixing uniformity, and improve the quality of the display screen. Furthermore, the large-angle light from any one of the red (R), blue (B), and green (G) subpixels can only enter the adjacent white (W) subpixel, and not the other subpixels, thereby avoiding the cross-color problem and achieving a good color mixing effect, good display quality, and higher luminance.

[0057] In an exemplary embodiment, the arrangement order of the first pixel, the second pixel, and the third pixel in the pixel structures shown in Figures 3 and 4 may be interchangeable. For example, each repeat unit 30 in Figure 3 may include a second pixel, a first pixel, a third pixel, etc., arranged sequentially along the first direction. However, the embodiments of the present disclosure are not limited thereto.

[0058] In an exemplary embodiment, in each repeat unit, the sub-pixels of the same color have the same size. For example, as shown in Figures 3 and 4, in each repeat unit 30, three red (R) sub-pixels have the same size, or three blue (B) sub-pixels have the same size, or three green (G) sub-pixels have the same size, or nine white (W) sub-pixels have the same size. This ensures display uniformity.

[0059] In an exemplary embodiment, in each repeat unit, all sub-pixels have the same shape, size, and arrangement angle. For example, as shown in Figures 3 and 4, in each repeat unit 30, 18 sub-pixels have the same shape, size, and arrangement angle. This ensures display uniformity.

[0060] In an exemplary embodiment, since the luminous efficiency and lifetime of sub-pixels of different colors are different, in one repeating unit, the areas corresponding to the sub-pixels of different colors can be set according to the luminous efficiency and lifetime of the sub-pixels of different colors to improve the brightness and lifetime of the product.

[0061] For example, based on the design requirements for brightness improvement proportion and lifetime, the area ratio of four types of subpixels, i.e., red (R) subpixel, blue (B) subpixel, green (G) subpixel, and white (W) subpixel, in one repeat unit can be flexibly adjusted.

[0062] For example, if the luminous efficiency of a blue (B) subpixel at the same current intensity is lower than the luminous efficiency of a green (G) subpixel and the luminous efficiency of a red (R) subpixel at the same current intensity, and the ratio of the numbers of red (R), green (G), and blue (B) subpixels in one repeat unit is 1:1:1, the area of ​​the blue (B) subpixel can be increased, i.e., the area of ​​the blue (B) subpixel can be set to be larger than the area of ​​the red (R) subpixel and larger than the area of ​​the green (G) subpixel, thereby improving the brightness and service life of the pixel structure.

[0063] For example, the contribution values ​​of the RGB subpixels to the brightness of white light are approximately 20% to 25% for the red (R) subpixel, approximately 50% to 60% for the green (G) subpixel, and approximately 20% to 25% for the blue (B) subpixel. The lifetimes of the RGB organic materials are approximately 17,000 to 18,000 hours for the red (R) subpixel, approximately 26,000 to 27,000 hours for the green (G) subpixel, and approximately 6,000 to 7,000 hours for the blue (B) subpixel. Therefore, the area ratio of the red (R), green (G), and blue (B) subpixels in one repeat unit can be set to approximately 1:1:2.

[0064] In an exemplary embodiment, the shape of each subpixel is a hexagon with three sets of opposite sides parallel to each other, at least two sets of opposite sides having equal lengths, and six interior angles all 120°, and the length of each repeat unit is three times its width. For example, as shown in FIG. 7, the length of each repeat unit may refer to its equivalent length in the first direction (Pitch_H), and the width of each repeat unit may refer to its equivalent length in the second direction (Pitch_V). Here, FIG. 7 shows one repeat unit as an example.

[0065] In an exemplary embodiment, the minimum distance Space between any two adjacent sub-pixels may be equal, as shown in Figures 7 and 8. Here, the minimum distance Space between two adjacent sub-pixels may indicate the width of the BM or CF overlay.

[0066] In an exemplary embodiment, as shown in FIG. 8, the minimum distance Space between any two adjacent subpixels may be equal to 0, i.e., Space=0, indicating no BM or CF overlay. Alternatively, as shown in FIG. 7, the minimum distance between any two adjacent subpixels may be greater than 0, i.e., Space=X μm (microns, X ≠ 0 and X > 0), indicating a BM or CF overlay width of X μm. For example, as shown in FIG. 9, the minimum distance Space between any two adjacent subpixels may be perfectly coincident, i.e., the distance between the six sides of any two hexagonal subpixels may all be X μm. For example, the minimum distance Space between any two adjacent subpixels within the same repeat unit may be approximately 0.6 μm.

[0067] In an exemplary embodiment, as shown in FIG. 8, in each repeat unit, all subpixels have the same shape, size, and arrangement angle, the minimum distance Space between any two adjacent subpixels is equal to 0, and the shape of the subpixel is a parallelepiped. As shown in FIG. 6, the subpixel width R1 may refer to the minimum distance in the first direction between the second side (side bc) and the fifth side (side ef) of the subpixel, the subpixel equivalent length R2 may refer to the minimum distance in the second direction between the vertices d and f of the subpixel, and the subpixel length R3 may refer to the minimum distance in the second direction between the vertices d and a of the subpixel. Therefore, the length and width of the repeat unit are as shown in Equations (2) and (3), where the repeat unit length Pitch_H may be six times the subpixel width R1, and the repeat unit width Pitch_V may be the sum of twice the subpixel equivalent length R2 and the subpixel length R3.

[0069] In the formula, Pitch_H denotes the length of the repeat unit, Pitch_V denotes the width of the repeat unit, R1 denotes the width of the sub-pixel, R2 denotes the equivalent length of the sub-pixel, and R3 denotes the length of the sub-pixel.

[0070] In an exemplary embodiment, as shown in Figure 7, in each repeat unit, all subpixels have the same shape, size, and arrangement angle, the minimum distance Space between any two adjacent subpixels is greater than 0, and the subpixel shape is a parallelepiped. As shown in Figure 6, the subpixel width R1 may refer to the minimum distance in the first direction between the second side (side bc) and the fifth side (side ef) of the subpixel, the subpixel equivalent length R2 may refer to the minimum distance in the second direction between the vertices d and f of the subpixel, and the subpixel length R3 may refer to the minimum distance in the second direction between the vertices d and a of the subpixel. Therefore, the repeat unit length and the repeat unit width are as shown in Equations (4) and (5).

[0072] where Pitch_H is the length of the repeat unit (i.e., the equivalent distance of the repeat unit in the first direction), and W R1 is the width of the white (W) subpixel, and R R1 indicates the width of the red (R) subpixel, and G R1 indicates the width of the green (G) subpixel, and B R1denotes the width of the blue (B) subpixel, Space denotes the minimum distance between any two adjacent subpixels, Pitch_V denotes the width of the repeat unit (i.e., the equivalent distance of the repeat unit in the second direction), and R R3 indicates the length of the red (R) subpixel, and G R2 indicates the equivalent length of the white (W) sub-pixel, and B R3 indicates the length of the blue (B) subpixel, and sqrt(3) indicates the square root of three.

[0073] In an exemplary embodiment, the pixel structure may be set to satisfy one or more of the following five conditions: Condition 1: Pitch_V=Pixel_Pitch, Pitch_H=3×Pixel_Pitch, i.e., the length of each repeating unit, Pitch_H, is three times the width of each repeating unit, Pitch_V, and Pixel_Pitch indicates the distance between two pixels. Condition 2: In one repeat unit, the sizes of the four subpixels, i.e., the red (R) subpixel, the green (G) subpixel, the blue (B) subpixel, and the white (W) subpixel, are all the same, i.e., in one minimum repeat unit, the sizes of the 18 subpixels are all the same. Condition 3: The minimum distance Space between any two adjacent subpixels is 0, i.e., there is no BM or CF overlay. Condition 4: Equation (2) and Equation (3) are satisfied, i.e., the length of the repeat unit Pitch_H is six times the width R1 of the subpixel, and the width of the repeat unit Pitch_V may be the sum of twice the equivalent length R2 of the subpixel and the length R3 of the subpixel. Condition 5: The shape of each sub-pixel is a hexagon, and all six interior angles of the hexagon are 120°. This can improve the aperture ratio. For example, the pixel structure can be set to satisfy all of the above five conditions. In this case, compared with strictly arranged square, triangular, and other hexagonal pixel array designs, the pixel structure according to the exemplary embodiment of the present disclosure has a larger aperture ratio due to the sub-pixel size calculated according to the above five conditions, thereby resulting in brighter light emission.

[0074] In an exemplary embodiment, three pixels arranged side by side can constitute one repeat unit, and by arranging a repeat unit array based on the repeat unit, pixel structure arrangements of different resolutions can be realized. For example, when FHD (Full High Definition) display is set and the resolution reaches 1920 x 1080, by configuring 1920 / 3 = 640 columns of repeat units in the first direction (i.e., horizontal direction) and configuring 1080 rows of repeat units in the second direction (i.e., vertical direction), the resolution of FHD 1920 x 1080 can be realized.

[0075] In an exemplary embodiment, when arranging the repeat unit array, the size used may be determined according to the AA area and resolution of the display device. For example, assume that the pixel structure in the embodiment of the present disclosure is applied to a 0.71-inch Full High Definition (FHD) display device. Since the display size is 0.71 inches and the resolution is FHD 1920 x 1080, the distance Pixel_Pitch between two pixels is calculated to be 8.1 μm. Then, calculated from Equations (2) and (3), the length Pitch_H of each repeat unit may be 8.1 μm × 3 = 24.3 μm, and the width Pitch_V of each repeat unit may be 8.1 μm. Thus, when arranging the repeat units in an array, it is satisfied that the length Pitch_H of each repeat unit is three times the width Pitch_V of each repeat unit.

[0076] In an exemplary embodiment, the pixel structure may further include a plurality of data signal lines (Source Lines), where each second pixel column is controlled by one data signal line and each first pixel column is controlled by two data signal lines, thereby reducing the number of data signal lines in the pixel structure by one.

[0077] In an exemplary embodiment, the pixel structure may further include a plurality of data signal lines, where three of the four different color sub-pixels in each pixel are controlled by two data signal lines, and the sub-pixels other than the three of the four different color sub-pixels in each pixel are controlled by the same data signal line, thereby reducing the number of data signal lines in the pixel structure.

[0078] In an exemplary embodiment, when the pixel structure is in a first display mode, the pixel structure may display a pixel row set consisting of two adjacent pixel rows as a unit, or when the pixel structure is in a second display mode, the pixel structure may display a pixel column set consisting of one first pixel column and one second pixel column as a unit, or when the pixel structure is in a third display mode, the pixel structure may display each pixel as a unit.

[0079] Figure 10 is a display schematic diagram of a pixel structure in an exemplary embodiment of the present disclosure, Figure 11 is another display schematic diagram of a pixel structure in an exemplary embodiment of the present disclosure, and Figure 12 is a further display schematic diagram of a pixel structure in an exemplary embodiment of the present disclosure. Display methods of pixel structures according to embodiments of the present disclosure will be described in detail below with reference to Figures 10, 11, and 12. Figures 10, 11, and 12 all illustrate the pixel structure shown in Figure 3 as an example.

[0080] In an exemplary embodiment, when the pixel structure is in the first display mode, the pixel structure may display a set of two adjacent pixel rows. Each pixel row includes a white (W), red (R), blue (B), and green (G) subpixel, and the white (W) subpixel separates any two of the red (R), blue (B), and green (G) subpixels. For example, when displaying horizontal black and white lines, the RGBW pixel arrangement realized by the repeat unit array can be realized in the form of four black and white lines shown in FIG. 10. As can be seen from FIG. 10, when displaying horizontal black and white lines, one black line or one white line is realized by two rows of subpixels rather than by the pixel points shown in FIG. 10. This allows for higher resolution when displaying black and white lines, and the resolution of the horizontal lines can be improved by one-third. Here, FIG. 10 shows an example of displaying two white lines and two black lines.

[0081] In an exemplary embodiment, when the pixel structure is in the second display mode, the pixel structure may display in units of pixel column sets, each consisting of one first pixel column and one second pixel column. The first pixel column in each pixel column set includes a red (R), green (G), and blue (B) subpixel, and the second pixel column in each pixel column set includes only a white (W) subpixel. For example, when an RGBW pixel array realized by a repeat unit array displays vertical black and white lines, it can be realized using the vertical black and white line display format shown in FIG. 11. As can be seen from FIG. 11, one white line or one black line includes two subpixels in the horizontal direction, and the two subpixels may include one white (W) subpixel. This can improve luminance and avoid cross-color issues. The first pixel column includes three subpixels of red (R), green (G), and blue (B) colors, and can display color stripes. Here, FIG. 11 shows an example of displaying three white lines and three black lines. 11, the red (R), green (G), and blue (B) subpixels in the first pixel column of each pixel column set output different display signals through two data signal lines, and all the white (W) subpixels in the second pixel column of each pixel column set output the same display signal through the same data signal line, thereby saving one data signal line.

[0082] In an exemplary embodiment, when the pixel structure is in the third display mode, the pixel structure displays each pixel as a unit. Each pixel includes three white (W) subpixels, one red (R) subpixel, one blue (B) subpixel, and one green (G) subpixel. For example, as shown in FIG. 12, an RGBW pixel array realized by a repeating unit array can display one pixel dot in the manner of three pixel dots as shown in FIG. 12. Here, FIG. 12 shows an example in which three pixel dots are lit. For example, as shown in FIG. 12, all white (W) subpixels in each pixel output the same display signal through the same data signal line, while the red (R) subpixel, green (G) subpixel, and blue (B) subpixel in each pixel output different display signals through two data signal lines. This pixel structure saves one data signal line.

[0083] An embodiment of the present disclosure further provides a method for driving a pixel structure, which may be the pixel structure in one or more of the above exemplary embodiments.

[0084] 13 is a schematic flow chart of a driving method of a pixel structure in an exemplary embodiment of the present disclosure. As shown in FIG. 13, the driving method includes: Step 1301: obtaining an original signal corresponding to each pixel in each frame, the original signal including original luminance values ​​corresponding to sub-pixels of three of four different colors; Step 1302: converting an original signal corresponding to each pixel into a target signal corresponding to each pixel, the target signal including target luminance values ​​corresponding to four different color sub-pixels; and step 1303 of outputting a target signal corresponding to each pixel.

[0085] For example, assume that three of the four different color subpixels include a red (R) subpixel, a blue (B) subpixel, and a green (G) subpixel, and the other subpixels are white (W) subpixels. Generally, in a standard video signal or image signal for each frame, the original signal corresponding to each pixel only includes an R signal (i.e., the original luminance value of the red (R) subpixel in each pixel), a G signal (i.e., the original luminance value of the green (G) subpixel in each pixel), and a B signal (i.e., the original luminance value of the blue (B) subpixel in each pixel), but does not include a W signal (i.e., the original luminance value of the white (W) subpixel). Therefore, for driving the pixel structure of the RGBW pixel array according to the embodiment of the present disclosure, after receiving the original signals corresponding to each pixel in the video or image for each frame, the original signals corresponding to each pixel in the received video or image for each frame are converted into target signals corresponding to each pixel, and the converted target signals corresponding to each pixel are output to the pixel structure to achieve accurate image display. The target signal corresponding to each pixel may include an R signal (i.e., the total luminance value of the red (R) sub-pixel in each pixel), a G signal (i.e., the total luminance value of the green (G) sub-pixel in each pixel), a B signal (i.e., the total luminance value of the blue (B) sub-pixel in each pixel), and a W signal (i.e., the total luminance value of the white (W) sub-pixel in each pixel). In this way, by adopting a driving method that is compatible with the pixel structure arrangement, accurate color display can be achieved.

[0086] In an exemplary embodiment, step 1302 may include the following steps 1401 to 1402. In step 1401, the maximum and minimum values ​​of the original signal corresponding to each pixel are determined. In step 1402, a target signal corresponding to each pixel is determined based on the maximum and minimum values ​​of the original signal corresponding to each pixel.

[0087] Here, the maximum value of the original signal corresponding to each pixel may refer to the maximum value of original luminance values ​​corresponding to sub-pixels of three of the four different colors in the original signal corresponding to each pixel, and the minimum value of the original signal corresponding to each pixel may refer to the minimum value of original luminance values ​​corresponding to sub-pixels of three of the four different colors in the original signal corresponding to each pixel.

[0088] For example, an original signal corresponding to each pixel generally includes only an R signal (i.e., the original luminance value of the red (R) subpixel in each pixel), a G signal (i.e., the original luminance value of the green (G) subpixel in each pixel), and a B signal (i.e., the original luminance value of the blue (B) subpixel in each pixel), but does not include a W signal (i.e., the original luminance value of the white (W) subpixel). The maximum value of the original signal corresponding to each pixel may refer to the maximum value among the original luminance values ​​of the red (R) subpixel, the blue (B) subpixel, and the green (G) subpixel in the original signal corresponding to each pixel. The minimum value of the original signal corresponding to each pixel may refer to the minimum value among the original luminance values ​​of the red (R) subpixel, the blue (B) subpixel, and the green (G) subpixel in the original signal corresponding to each pixel.

[0089] In an example embodiment, step 1402 may include determining a target signal corresponding to each pixel based on the maximum and minimum values ​​of the original signal corresponding to each pixel according to the following equation:

[0091] In the formula, R0 is the total luminance value of the red (R) subpixel in the original signal, B0 is the total luminance value of the blue (B) subpixel in the original signal, G0 is the total luminance value of the green (G) subpixel in the original signal, min(R0,G0,B0) is the minimum value of the original signal, max(R0,G0,B0) is the maximum value of the original signal, W1 is the total luminance value of the white (W) subpixel in the target signal, gain is a gain coefficient, R1 is the total luminance value of the red (R) subpixel in the target signal, B1 is the total luminance value of the blue (B) subpixel in the target signal, and G1 is the total luminance value of the green (G) subpixel in the target signal.

[0092] In an exemplary embodiment, each pixel in the pixel structure includes one red (R) subpixel, one blue (B) subpixel, one green (G) subpixel, and three white (W) subpixels. W1 is uniformly divided to obtain luminance values ​​corresponding to the three white (W) subpixels. The three white (W) subpixels in a pixel have the same luminance value. Alternatively, different luminance values ​​may be assigned to white (W) subpixels at different positions, taking into account factors such as pixel life. For example, a white (W) subpixel adjacent to a blue (B) subpixel in a pixel may be assigned a relatively large luminance value. For example, the ratio of the luminance values ​​of the white (W) subpixel adjacent to the red (R) subpixel, the white (W) subpixel adjacent to the green (G) subpixel, and the white (W) subpixel adjacent to the blue (B) subpixel may be 1:1:2. That is, the luminance value of the white (W) subpixel adjacent to the blue (B) subpixel may be 0.5W1, the luminance value of the white (W) subpixel adjacent to the red (R) subpixel may be 0.25W1, and the luminance value of the white (W) subpixel adjacent to the green (G) subpixel may be 0.25W1, but the embodiments of the present disclosure are not limited thereto.
