Description

Technical Field

[0001] This invention belongs to the field of optical display technology. Specifically, this invention relates to a pixel arrangement structure and a display panel. Background Technology

[0002] As display technology advances towards higher definition and miniaturization, the demand for high-resolution silicon-based microdisplays in fields such as virtual reality (VR) and augmented reality (AR) is becoming increasingly urgent. Silicon-based microdisplays use silicon-based materials as the driving backplane and possess advantages such as high pixel density, fast response speed, and high integration. Among them, silicon-based organic light-emitting diode (OLED) displays, due to their self-emissive characteristics, high contrast, and wide viewing angle, have become one of the core technology directions in the field of high-resolution microdisplays.

[0003] However, with the continuous improvement of display resolution, the size of individual pixels continues to decrease, and the pixel pitch shortens, leading to increasingly prominent crosstalk problems between adjacent pixels. Crosstalk mainly includes two forms: electrical crosstalk and optical crosstalk. Electrical crosstalk is usually caused by parasitic capacitance, current leakage, or signal coupling in the drive circuit. When the pixel size is miniaturized, the backplane circuit density increases, and the drive signal paths are close to each other, easily generating electrical signal interference and affecting the accuracy of independent pixel control. Optical crosstalk is mainly caused by the optical paths between pixels being too close, insufficient optical barrier of the encapsulation layer or isolation layer, or light diffusion caused by material reflection and refraction, thereby causing image blurring, decreased contrast, or color distortion.

[0004] Especially in silicon-based OLED displays, the turn-on voltages of different color emitting materials differ. For example, blue (B) OLEDs have higher turn-on voltages, while red (R) OLEDs have lower turn-on voltages. When a blue pixel is lit, it can easily cause weak light emission on adjacent red pixels, a phenomenon known as electrical light leakage, resulting in a grayish image, reduced color gamut, and color distortion. This problem is particularly pronounced in traditional RGB stripe arrangements because the boundary length between B and R pixels is relatively large, resulting in a wide physical contact area and numerous optical and electrical interference paths, thus amplifying the crosstalk effect. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention provides a pixel arrangement structure with the purpose of improving crosstalk reduction.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a pixel arrangement structure, comprising pixels arranged in an array, wherein the pixels include at least one red sub-pixel, at least one green sub-pixel and at least one blue sub-pixel; A color group is formed by a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In a color group: along the horizontal direction, the red sub-pixel and the green sub-pixel are arranged sequentially with a first interval; along the vertical direction, the blue sub-pixel is disposed on one side of the red sub-pixel and the green sub-pixel; along the horizontal direction, the length of the blue sub-pixel is greater than the length of the red sub-pixel.

[0007] The length of the red sub-pixel, the length of the green sub-pixel, and the total length of the first interval are equal to the length of the blue sub-pixel.

[0008] The pixel includes a color group.

[0009] The pixel includes two color groups, namely the first color group and the second color group; In the first color group, along the vertical direction, the blue sub-pixel is disposed below or above the red and green sub-pixels; In the second color group, along the vertical direction, the blue sub-pixel is positioned above or below the red and green sub-pixels.

[0010] The pixel includes four color groups, namely a first color group, a second color group, a third color group, and a fourth color group; along the horizontal direction, the first color group and the second color group are arranged adjacent to each other, and the third color group and the fourth color group are arranged adjacent to each other; along the vertical direction, the first color group and the third color group are arranged adjacent to each other, and the second color group and the fourth color group are arranged adjacent to each other. In the first color group and the fourth color group, along the vertical direction, the blue sub-pixel is disposed below or above the red sub-pixel and the green sub-pixel; In the second and third color groups, the blue sub-pixel is positioned above or below the red and green sub-pixels along the vertical direction.

[0011] The blue sub-pixel has a protrusion on the side near the red and green sub-pixels; the protrusion includes a first side near the red sub-pixel and a second side near the green sub-pixel.

[0012] The protrusion is disposed at the first interval and is horizontal in the direction of the first side extending toward the red sub-pixel and the second side extending toward the green sub-pixel. Both the red sub-pixel and the green sub-pixel are constricted at the protrusion.

[0013] The first side is set parallel to the second side.

[0014] The first side and the second side have a preset angle, which is greater than 0 and less than 180°.

[0015] The blue sub-pixel has a protrusion on the side near the green sub-pixel, the protrusion being located on the side of the green sub-pixel away from the red sub-pixel and extending towards the green sub-pixel; the green sub-pixel has an elongation on the side near the red sub-pixel, the elongation extending towards the red sub-pixel, the green sub-pixel being constricted at the protrusion, and the red sub-pixel being constricted at the elongation.

[0016] The present invention also provides a display panel including the aforementioned pixel arrangement structure.

[0017] The pixel arrangement structure of this invention features staggered pixel layout within each display unit. This reduces the physical boundaries of individual pixels, lowers optical and electrical crosstalk, and reduces the boundary size. Simultaneously, the staggered layout reduces direct optical path overlap, improving color mixing uniformity. The staggered arrangement directly reduces the direct coupling paths between pixels, lowering crosstalk by 30%-50%. Attached Figure Description

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0020] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0021] The technical approach of this invention includes: In the pixel design of existing silicon-based OLED displays, the standard RGB pixel arrangement (such as RGB stripe arrangement) is the mainstream solution, but its structural design further amplifies the aforementioned crosstalk problem. In the standard RGB pixel arrangement, R pixels and B pixels are usually distributed adjacently side by side, with a large physical boundary area between them; this large boundary area not only increases the direct superposition of optical signals between adjacent pixels but also provides a longer coupling path for leakage current from B pixels to R pixels. The superposition of these two crosstalk mechanisms makes it difficult to effectively solve the crosstalk problem of silicon-based OLED displays with standard RGB pixel design in high-resolution scenarios through conventional optimization methods. Figure 10 As shown, this is particularly evident in existing standard RGB pixel designs because the boundary between the blue and red subpixels is large, making it easy for the blue subpixel to leak current into the red subpixel. Therefore, it is necessary to reduce the boundary between the red and blue subpixels and develop pixel designs that improve crosstalk. The solution in this application is as follows: Firstly, such as Figures 1 to 9 As shown, the present invention provides a pixel arrangement structure, including pixels arranged in an array, wherein each pixel includes at least one red sub-pixel 1, at least one green sub-pixel 2 and at least one blue sub-pixel 3; A color group is formed by a red subpixel 1, a green subpixel 2, and a blue subpixel 3. Within a color group: horizontally, the red subpixel 1 and green subpixel 2 are arranged sequentially with a first interval; vertically, the blue subpixel 3 is located on one side of the red subpixel 1 and green subpixel 2; horizontally, the length of the blue subpixel 3 is greater than the length of the red subpixel 1. This staggered arrangement of subpixels within each display unit reduces the physical boundaries of individual subpixels, decreases the intersection size, and reduces optical and electrical crosstalk. Simultaneously, the staggered arrangement reduces direct optical path overlap, improving color mixing uniformity. The staggered arrangement directly reduces the direct coupling paths between pixels, reducing crosstalk by 30%-50%.

[0022] like Figures 1 to 9As shown, in this embodiment of the invention, the total length of the red sub-pixel 1, the green sub-pixel 2, and the first interval is equal to the length of the blue sub-pixel 3. This length setting ensures that the horizontal coverage of the blue sub-pixel 3 exactly includes the red sub-pixel 1, the green sub-pixel 2, and the first interval between them. This compensates for insufficient blue brightness by increasing the light-emitting area, while preventing the blue sub-pixel 3 from overflowing into adjacent areas due to being too long, or from causing local blue deficiency due to being too short, thus avoiding color cast and ensuring full-color uniformity. The horizontal boundary of the blue sub-pixel 3 is strictly limited to its own color group and will not overlap with sub-pixels of adjacent color groups. Combined with the first interval between the red and green sub-pixels 2, it can further cut off cross-group crosstalk between red and blue, as well as direct crosstalk between red and green, making crosstalk suppression more thorough. Moreover, it can make full use of the horizontal dimension without redundancy or waste, and will not force the sub-pixels to shrink and sacrifice resolution due to size misalignment, ensuring high resolution. Example 1

[0023] like Figure 1 As shown, in this embodiment, a pixel includes a color group. In a color group: along the horizontal direction, red sub-pixel 1 and green sub-pixel 2 are arranged sequentially with a first interval; along the vertical direction, blue sub-pixel 3 is disposed on one side of red sub-pixel 1 and green sub-pixel 2; along the horizontal direction, the length of blue sub-pixel 3 is greater than the length of red sub-pixel 1.

[0024] like Figure 1 As shown, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0025] like Figure 1 As shown, the protrusion is located at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion, and the first and second sides are arranged parallel to each other. The parallel sides make the protrusion regular and symmetrical, the RGB light mixes evenly, the color deviation is reduced, and the regular structure simplifies the manufacturing process. Example 2

[0026] like Figure 2As shown, in this embodiment, the pixel includes two color groups: a first color group and a second color group. In the first color group, along the vertical direction, the blue sub-pixel 3 is positioned below or above the red sub-pixel 1 and the green sub-pixel 2. In the second color group, along the vertical direction, the blue sub-pixel 3 is positioned above or below the red sub-pixel 1 and the green sub-pixel 2. The blue sub-pixels 3 of the two color groups alternate vertically, dispersing the boundary areas between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3, avoiding concentrated superposition of crosstalk and improving the crosstalk suppression effect. The special pixel arrangement optimizes the distribution of different color pixels, making the color transition more natural. For example, when displaying gradient colors, different colors can be mixed more smoothly, reducing color banding and presenting a richer and more realistic color effect.

[0027] like Figure 2 As shown, in the same color group, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0028] like Figure 2 As shown, within the same color group, the protrusion is positioned at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion, and the first and second sides are arranged parallel to each other. The parallel sides make the protrusion regular and symmetrical, resulting in uniform RGB light mixing, reduced color deviation, and a simplified manufacturing process due to the regular structure. Example 3

[0029] like Figure 3 As shown, in this embodiment, the pixel includes four color groups, namely the first color group, the second color group, the third color group and the fourth color group; along the horizontal direction, the first color group and the second color group are arranged adjacent to each other, and the third color group and the fourth color group are arranged adjacent to each other; along the vertical direction, the first color group and the third color group are arranged adjacent to each other, and the second color group and the fourth color group are arranged adjacent to each other. In the first and fourth color groups, along the vertical direction, the blue sub-pixel 3 is positioned below or above the red sub-pixel 1 and the green sub-pixel 2. In the second and third color groups, along the vertical direction, the blue sub-pixel 3 is positioned above or below the red sub-pixel 1 and the green sub-pixel 2.

[0030] Compared to Embodiments 1 and 2, this embodiment has the fewest intersections between red sub-pixels 1 and blue sub-pixels 3, resulting in the best crosstalk reduction effect. The four color groups of blue sub-pixels 3 alternate vertically, dispersing the intersections between red sub-pixels 1 and blue sub-pixels 3, and between green sub-pixels 2 and blue sub-pixels 3, avoiding concentrated crosstalk accumulation and further improving the crosstalk suppression effect.

[0031] like Figure 3 As shown, in the same color group, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0032] like Figure 3 As shown, within the same color group, the protrusion is positioned at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion, and the first and second sides are arranged parallel to each other. The parallel sides make the protrusion regular and symmetrical, resulting in uniform RGB light mixing, reduced color deviation, and a simplified manufacturing process due to the regular structure. Example 4

[0033] like Figure 4 As shown, in this embodiment, a pixel includes a color group. In a color group: along the horizontal direction, red sub-pixel 1 and green sub-pixel 2 are arranged sequentially with a first interval; along the vertical direction, blue sub-pixel 3 is disposed on one side of red sub-pixel 1 and green sub-pixel 2; along the horizontal direction, the length of blue sub-pixel 3 is greater than the length of red sub-pixel 1.

[0034] like Figure 4 As shown, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0035] like Figure 4As shown, the protrusion is located at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion. The first and second sides have a preset angle, which is greater than 0° and less than 180°. The non-parallel sides on the protrusion can further reduce the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3, cutting off crosstalk paths and reducing optical and electrical crosstalk. Example 5

[0036] like Figure 5 As shown, in this embodiment, the pixel includes two color groups: a first color group and a second color group. In the first color group, along the vertical direction, the blue sub-pixel 3 is positioned below or above the red sub-pixel 1 and the green sub-pixel 2. In the second color group, along the vertical direction, the blue sub-pixel 3 is positioned above or below the red sub-pixel 1 and the green sub-pixel 2. The blue sub-pixels 3 of the two color groups alternate vertically, dispersing the boundary areas between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3, avoiding concentrated superposition of crosstalk and improving the crosstalk suppression effect. The special pixel arrangement optimizes the distribution of different color pixels, making the color transition more natural. For example, when displaying gradient colors, different colors can be mixed more smoothly, reducing color banding and presenting a richer and more realistic color effect.

[0037] like Figure 5 As shown, in the same color group, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0038] like Figure 5 As shown, within the same color group, the protrusion is positioned at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion, and the first and second sides are arranged parallel to each other. The parallel sides make the protrusion regular and symmetrical, resulting in uniform RGB light mixing, reduced color deviation, and a simplified manufacturing process due to the regular structure. Example 6

[0039] like Figure 6As shown, in this embodiment, the pixel includes four color groups, namely the first color group, the second color group, the third color group and the fourth color group; along the horizontal direction, the first color group and the second color group are arranged adjacent to each other, and the third color group and the fourth color group are arranged adjacent to each other; along the vertical direction, the first color group and the third color group are arranged adjacent to each other, and the second color group and the fourth color group are arranged adjacent to each other. In the first and fourth color groups, along the vertical direction, the blue sub-pixel 3 is positioned below or above the red sub-pixel 1 and the green sub-pixel 2. In the second and third color groups, along the vertical direction, the blue sub-pixel 3 is positioned above or below the red sub-pixel 1 and the green sub-pixel 2.

[0040] Compared to Embodiments 4 and 5, this embodiment has the fewest intersections between red sub-pixels 1 and blue sub-pixels 3, resulting in the best crosstalk reduction effect. The four color groups of blue sub-pixels 3 alternate vertically, dispersing the intersections between red sub-pixels 1 and blue sub-pixels 3, and between green sub-pixels 2 and blue sub-pixels 3, avoiding concentrated crosstalk accumulation and further improving the crosstalk suppression effect.

[0041] like Figure 6 As shown, in the same color group, the blue sub-pixel 3 has a protrusion on the side near the red sub-pixel 1 and the green sub-pixel 2; the protrusion includes a first side near the red sub-pixel 1 and a second side near the green sub-pixel 2. By setting the protrusion, the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3 is reduced, the crosstalk path is cut off, and optical and electrical crosstalk is reduced.

[0042] like Figure 6 As shown, within the same color group, a protrusion is positioned at the first interval and runs horizontally. The first side of the protrusion extends towards the red sub-pixel 1, and the second side extends towards the green sub-pixel 2. Both the red sub-pixel and the green sub-pixel 2 are constricted at the protrusion. The first and second sides have a preset angle, which is greater than 0° and less than 180°. The non-parallel sides on the protrusion further reduce the boundary area between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3, cutting off crosstalk paths and reducing optical and electrical crosstalk. Example 7

[0043] like Figure 7 As shown, in this embodiment, a pixel includes a color group. In a color group: along the horizontal direction, red sub-pixel 1 and green sub-pixel 2 are arranged sequentially with a first interval; along the vertical direction, blue sub-pixel 3 is disposed on one side of red sub-pixel 1 and green sub-pixel 2; along the horizontal direction, the length of blue sub-pixel 3 is greater than the length of red sub-pixel 1.

Green sub-pixel 2 is constricted at the protrusion, and red sub-pixel 1 is constricted at the elongated portion. The elongated portion of green sub-pixel 2 reduces the boundary between red sub-pixel 1 and green sub-pixel 2, and the protrusion of blue sub-pixel 3 reduces the boundary between green sub-pixel 2 and blue sub-pixel 3. This dual effect can further reduce optical and electrical crosstalk. Example 8

[0045] like Figure 8 As shown, in this embodiment, the pixel includes two color groups, namely a first color group and a second color group. In the first color group, along the vertical direction, the blue sub-pixel 3 is disposed below or above the red sub-pixel 1 and the green sub-pixel 2. In the second color group, along the vertical direction, the blue sub-pixel 3 is disposed above or below the red sub-pixel 1 and the green sub-pixel 2. The blue sub-pixels 3 of the two color groups alternate vertically, dispersing the boundary areas between the red sub-pixel 1 and the blue sub-pixel 3, and between the green sub-pixel 2 and the blue sub-pixel 3, avoiding the concentrated superposition of crosstalk and improving the crosstalk suppression effect. The special pixel arrangement optimizes the distribution of different color pixels, making the color transition more natural. For example, when displaying gradient colors, different colors can be mixed more smoothly, reducing color banding and presenting a richer and more realistic color effect.

[0046] like Figure 8 As shown, in the same color group, the blue sub-pixel 3 has a protrusion on the side closer to the green sub-pixel 2. This protrusion is located on the side of the green sub-pixel 2 away from the red sub-pixel 1 and extends towards the green sub-pixel 2.

The green sub-pixel 2 is constricted at the protrusion, and the red sub-pixel 1 is constricted at the elongated portion. The elongated portion of the green sub-pixel 2 reduces the boundary between the red sub-pixel 1 and the green sub-pixel 2, and the protrusion of the blue sub-pixel 3 reduces the boundary between the green sub-pixel 2 and the blue sub-pixel 3. This dual effect can further reduce optical and electrical crosstalk.
