Description

[Technical Field]

[0001] This application claims priority from Chinese Patent Application No. 202410302679.3 entitled "Display Panel and Display Device," filed on March 15, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the field of display technology, and more particularly to a display panel, a display device, and a method for manufacturing a display panel. [Background technology]

[0003] Organic light-emitting diodes (OLEDs) are organic thin-film electroluminescent devices that have attracted much attention and are widely used in electronic display products due to their advantages such as simple manufacturing process, low cost, low power consumption, high brightness, wide viewing angle, high contrast, and flexible display. Summary of the Invention [Problem to be solved by the invention]

[0004] However, existing electronic display products are limited by their unique structural designs, and when applied to scenarios such as under-display recognition and transparent display, it is difficult to achieve both good touch functionality and good display functionality. [Means for solving the problem]

[0005] A first aspect of the present disclosure provides a display panel, the display panel including a display substrate, the display substrate including a first display area, the first display area including a number of first subpixels arranged in an array in a first direction, the first subpixels including at least two subpixel blocks, each of the first subpixels having at least two adjacent subpixel blocks, and the two adjacent subpixel blocks being separated by an isolation structure.

[0006] In an actual process, there is a risk that debris may enter the first subpixel, causing the first subpixel to fail to emit light. Therefore, in the above embodiment, by dividing the first subpixel into multiple subpixel blocks, only specific subpixel blocks will suffer from poor light emission due to debris, and the first subpixel itself will still be able to emit light, thereby reducing the risk of harmful substances such as debris entering the first subpixel and causing a malfunction in the display function of the display panel.

[0007] In a specific embodiment of the first aspect of the present disclosure, in the second direction, the display substrate includes a substrate and a display function layer located on the substrate. The display function layer includes a plurality of light-emitting elements, one for each subpixel block, and the light-emitting elements include a first electrode, a light-emitting function layer, and a second electrode sequentially stacked on the substrate, and in the same first subpixel, the first electrodes corresponding to adjacent subpixel blocks are electrically connected to each other. The isolation structure is located on the substrate and defines a plurality of isolation openings, and the light-emitting elements are positioned within the isolation openings.

[0008] In the above embodiment, the first electrodes of the two light-emitting elements in the same first subpixel are connected to each other, so the driving method of the entire pixel remains unchanged. Furthermore, the application of the isolation structure eliminates the need for a mask plate in the manufacturing process of the light-emitting elements, thereby eliminating the need to consider alignment accuracy issues in the manufacturing process and advantageously reducing the gap size between the light-emitting elements to improve the pixel PPI of the display panel.

[0009] In a specific embodiment of the first aspect of the present disclosure, the isolation structure includes a support portion and a crown portion sequentially stacked on a substrate, wherein the orthogonal projection of the support portion on the substrate is located within the orthogonal projection of the crown portion on the substrate, the support portion is a conductive structure, and the second electrode of the light-emitting element is located in the corresponding isolation opening and is connected to the support portion.

[0010] In the above-described embodiment, the gap between adjacent light-emitting elements has an overall isolation structure that is generally wider at the top and narrower at the bottom, thereby increasing the blocking effect of the isolation structure on the light-emitting functional layer during the manufacturing process of the light-emitting element and reducing the current crosstalk problem between adjacent light-emitting elements.

[0011] For example, optionally the support portion and crown portion are integrally formed.

[0012] For example, optionally the materials of the support and crown are different. Also optionally, for example, both the support and crown are electrically conductive structures.

[0013] In a specific embodiment of the first aspect of the present disclosure, the display substrate may further include a pixel definition layer located on one side of the isolation structure closer to the substrate, i.e., between the substrate and the isolation structure, and including a plurality of pixel openings corresponding to the isolation openings, respectively. The pixel openings position and restrict the light-emitting elements and expose the first electrodes, the pixel openings and the isolation openings correspond to each other, and the pixel openings communicate with the corresponding isolation openings.

[0014] In a specific embodiment of the first aspect of the present disclosure, in the first subpixel, the orthogonal projections of pixel openings corresponding to at least two subpixel blocks onto the substrate are located within the orthogonal projections of the same separated opening onto the substrate, or the orthogonal projections of pixel openings corresponding to each subpixel block onto the substrate are located within the orthogonal projections of each separated opening onto the substrate.

[0015] In a specific embodiment of the first aspect of the present disclosure, an edge of the first electrode overlaps an edge of the support to form a capacitor, and the pixel-defining layer covers the edges of the first electrodes to separate the support and the first electrodes, such that the orthogonal projection of the gap between two adjacent first electrodes onto the substrate is located within the orthogonal projection of the support onto the substrate.

[0016] When a light-emitting element is activated with a low voltage, its brightness is low, resulting in a weak visual effect. Furthermore, if there is leakage current, the light-emitting element may emit light even at a low gray level (e.g., a dark state), i.e., it cannot be turned off. In the above embodiment, by forming a capacitor using the supporting part and the edge portion of the first electrode, the capacitor can be charged during the turn-on phase of the light-emitting element, thereby improving the turn-on voltage of the light-emitting element so that the light-emitting element can reach the preset brightness requirement when emitting light. This design also prevents the light-emitting element from emitting light at a low gray level.

[0017] For example, the pixel-defining layer may optionally be an inorganic layer, the thickness of which may ensure that a capacitor formed between an edge of the first electrode and an edge of the support has sufficient capacitance.

[0018] In a specific embodiment of the first aspect of the present disclosure, the isolation structure extends continuously between two adjacent sub-pixel blocks so that light rays between the two adjacent sub-pixel blocks are blocked by the isolation structure.

[0019] In a specific embodiment of the first aspect of the present disclosure, in the first display region, the separation structure defines a plurality of light-transmitting apertures, and the light-transmitting apertures are located between adjacent subpixel blocks within the same first subpixel.

[0020] In the above-described embodiment, a transparent display or an under-display identification function such as fingerprint identification or under-display photography can be realized in the area of ​​the display panel where the light-transmitting opening is provided, so that a light-transmitting opening can be provided in the separation structure to allow light to pass through to the area of ​​the display panel where the light-transmitting opening is provided.

[0021] In a specific embodiment of the first aspect of the present disclosure, the display panel may further include a touch structure, where the touch structure is located on the light-emitting side of the display substrate and includes a touch electrode, the touch electrode has a grid structure, and the orthogonal projection of the grid lines of the touch electrode onto the display substrate is located at the gaps of the first sub-pixels.

[0022] In the above embodiment, by providing a light-transmitting opening for transmitting light inside the first subpixel, the adjacent length between the light-transmitting opening and the grid line can be reduced or the adjacent length between the light-transmitting opening and the grid line can be avoided, thereby reducing the problem of signal interference when the touch function and the display function are driven.

[0023] In a specific embodiment of the first aspect of the present disclosure, the orthogonal projection of the first electrode onto the substrate is located outside the orthogonal projection of the light-transmitting aperture onto the substrate, the substrate is provided with a conductive wire, and in a first subpixel having subpixel blocks, the first electrodes of the light-emitting elements corresponding to two adjacent subpixel blocks are connected to each other via the conductive wire. In this design, the first electrode is provided to avoid the light-transmitting aperture, which may improve the light transmittance of the display panel at the light-transmitting aperture and improve the light transmittance of the region where the light-transmitting aperture is located.

[0024] In another specific embodiment of the first aspect of the present disclosure, in the first subpixel, light-emitting elements corresponding to two adjacent subpixel blocks share the first electrode. For example, at the position where the light-transmitting aperture is located, the first electrode may be provided with a via hole overlapping the light-transmitting aperture to avoid blocking of light rays entering the light-transmitting aperture.

[0025] In another specific embodiment of the first aspect of the present disclosure, the first electrode includes a reflective electrode layer and a transparent electrode layer stacked on a substrate, the reflective electrode layer is located between the transparent electrode layers, in a first subpixel having a subpixel block, the first electrodes of the light-emitting elements in the subpixel block are connected via the transparent electrode layer, and the orthogonal projection of the light-transmitting aperture onto the substrate is located within the orthogonal projection of the transparent electrode layer onto the substrate, With this design, the setting of the separating aperture does not increase the difficulty of the manufacturing process of the display substrate and does not affect the layout of circuits within the substrate.

[0026] In a specific embodiment of the first aspect of the present disclosure, the emission color of the first subpixel is selected from at least one of red, green, and blue.

[0027] In a specific embodiment of the first aspect of the present disclosure, the first subpixel is a first-color subpixel that emits light of one color, and the first display area further includes a number of second-color subpixels and a number of third-color subpixels arranged in an array in a first direction, where adjacent first-color subpixels, second-color subpixels, and third-color subpixels constitute one pixel, and in each pixel, the first-color subpixel is located between the second-color subpixel and the third-color subpixel, the first-color subpixel, the second-color subpixel, and the third-color subpixel emit light of different colors, and the second-color subpixel and the third-color subpixel are all continuous. For example, optionally, the width of the first-color subpixel along the direction from the second-color subpixel to the third-color subpixel is equal to the width of the light-transmitting aperture. For example, optionally, the wavelengths of the emitted light of the second-color subpixel, the first-color subpixel, and the third-color subpixel sequentially decrease. For example, the second color subpixel, the first color subpixel, and the third color subpixel may selectively emit red light, green light, and blue light in sequence.

[0028] In the above embodiment, the light-transmitting apertures and the grid lines are spaced apart by the subpixel blocks, the second-color subpixels, and the third-color subpixels, so that they are not adjacent to the grid lines, which greatly reduces the problem of the touch function and the display function interfering with each other during driving.

[0029] In another specific embodiment of the first aspect of the present disclosure, the first subpixels are classified into first-color subpixels and second-color subpixels, each emitting light of at least two colors, and the first display area further includes a number of third-color subpixels arranged in an array in a first direction, where adjacent first-color subpixels, second-color subpixels, and third-color subpixels constitute one pixel, and in each pixel, the second-color subpixel is located between the first-color subpixel and the third-color subpixel, and the third-color subpixels are arranged in a continuous structure. For example, optionally, the light-transmitting apertures corresponding to the first-color subpixels and the second-color subpixels in each pixel are connected to each other. For example, optionally, the distance from the light-transmitting aperture to the grid line on one side of the first-color subpixel away from the second-color subpixel is greater than the distance from the first-color subpixel to the grid line. For example, optionally, the wavelengths of light emitted from the first-color subpixels, the second-color subpixels, and the third-color subpixels sequentially decrease. For example, the first color subpixel, the second color subpixel, and the third color subpixel may selectively emit red light, green light, and blue light in sequence.

[0030] In the above embodiment, the light-transmitting openings can have a large design area (increasing the number of light-transmitting openings), so that the area where the light-transmitting openings are located has a higher light transmittance; furthermore, this design makes the adjacent length between the light-transmitting openings and the grid lines short and the interval between adjacent positions large, thereby reducing the problem of touch function and display function interfering with each other when driven.

[0031] In another specific embodiment of the first aspect of the present disclosure, the first subpixels are classified into first-color subpixels, second-color subpixels, and third-color subpixels, each emitting light beams of at least three different colors, and each adjacent first-color subpixel, second-color subpixel, and third-color subpixel constitutes a pixel, and in each pixel, the second-color subpixel is located between the first-color subpixel and the third-color subpixel. For example, in each pixel, the light-transmitting apertures corresponding to the first-color subpixel, second-color subpixel, and third-color subpixel are selectively connected to each other. For example, selectively, the distance from the light-transmitting aperture to the grid line on one side of the first-color subpixel away from the second-color subpixel is greater than the distance from the first-color subpixel to the grid line, and the distance from the light-transmitting aperture to the grid line on one side of the third-color subpixel away from the second-color subpixel is greater than the distance from the third-color subpixel to the grid line. For example, the wavelengths of the emitted light from the first color subpixel, the second color subpixel, and the third color subpixel may selectively decrease sequentially, e.g., the first color subpixel, the second color subpixel, and the third color subpixel may selectively emit red light, green light, and blue light sequentially.

[0032] In the above embodiment, the light-transmitting openings can have a larger design area (increasing the number of light-transmitting openings), so that the area where the light-transmitting openings are located has a higher light transmittance; furthermore, this design makes the adjacent length between the light-transmitting openings and the grid lines shorter and the interval between adjacent positions larger, thereby reducing the problem of touch function and display function interfering with each other when driven.

[0033] In a specific embodiment of the first aspect of the present disclosure, the touch electrode includes a plurality of mesh holes surrounded by grid lines, each mesh hole corresponding to a subpixel, and the subpixel is located within the orthogonal projection of the corresponding mesh hole onto the display substrate. For example, the centroid of the orthogonal projection of the mesh hole onto the display substrate is aligned with the centroid of the corresponding subpixel. This design can reduce the brightness difference between light beams emitted from subpixels at the same viewing angle and in different directions, thereby reducing color shift.

[0034] In another specific embodiment of the first aspect of the present disclosure, the touch electrode includes a plurality of mesh holes surrounded by grid lines, each mesh hole corresponding to a first subpixel in a one-to-one correspondence, and the first subpixel is located within the orthogonal projection of the corresponding mesh hole onto the display substrate. For example, the centroid of the orthogonal projection of the mesh hole onto the display substrate is aligned with the centroid of the corresponding pixel. This design can reduce the brightness difference between light beams emitted from the first subpixel at the same viewing angle and in different directions, thereby reducing color shift.

[0035] For example, optionally, the touch electrode includes a plurality of first electrode bands arranged side by side and a plurality of second electrode bands arranged side by side, the first electrode bands and the second electrode bands intersect, and the first electrode bands and the second electrode bands are arranged in a grid-like structure.

[0074] Hereinafter, the technical solutions in the embodiments of this specification will be clearly and completely described with reference to the accompanying drawings in the embodiments of this specification, but obviously, the described embodiments are only a part of the embodiments of this specification, not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this specification without any creative work are all within the scope of protection of this specification.

[0075] In the manufacturing process of the light-emitting element of the display panel, contaminants such as dust, debris of processing materials, etc. may enter the openings for accommodating the light-emitting elements (e.g., the separation openings and pixel openings mentioned in the following examples), which may reduce the light-emitting performance of the light-emitting elements and even cause the light-emitting elements to quench when emitting light.

[0076] At least one embodiment of the present disclosure provides a display panel for solving at least the above technical problems. The display panel includes a display substrate, the display substrate including a first display region, the first display region including a number of first subpixels arranged in an array in a first direction, the first subpixels including at least two subpixel blocks, each of the first subpixels having at least two adjacent subpixel blocks separated by an isolation structure. By dividing the first subpixels into a plurality of subpixel blocks, light emission failure due to debris occurs only in a specific subpixel block, while the first subpixel itself can still emit light, thereby reducing the risk of harmful substances such as debris entering the subpixels and causing a malfunction of the display panel.

[0077] The structure of a display panel according to at least one embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings. Furthermore, in the drawings, a spatial Cartesian coordinate system is established with a substrate (or display substrate) in the display panel as a reference in order to intuitively represent the positional relationship of each component in the display panel. In the spatial Cartesian coordinate system, the X-axis and Y-axis are parallel to the plane on which the substrate is located, and the Z-axis is perpendicular to the plane on which the substrate is located.

[0078] 1 to 3, a display substrate 10 in a display panel includes a display area 11 and a frame area 12 surrounding the display area 11. Subpixels (which may be referred to as sub-pixels) that emit light beams of different colors, such as R, G, and B, are arranged in the display area 11. For example, three adjacent subpixels R, G, and B constitute one pixel (which may be referred to as a large pixel), and at least one subpixel (subpixel G in the figure) includes at least two spaced-apart subpixel blocks (e.g., subpixel blocks G1 and G2). In this case, even if subpixel block G1 becomes unable to emit light due to the intrusion of debris, subpixel block G2 ensures that a certain amount of light beams from subpixel G are emitted. The first direction may be a direction parallel to the X-axis or a direction parallel to the Y-axis.

[0079] In the embodiments of the present disclosure, all subpixels including multiple subpixel blocks are collectively referred to as first subpixels. In this case, if all subpixels in a display panel are designed to include subpixel blocks, the display panel includes only first subpixels, and in this case, the first subpixels emit light beams of various colors. In the case where some of the subpixels in a display panel are designed to include subpixel blocks, the some of the subpixels are referred to as first subpixels, and the other subpixels are classified as other types of subpixels, such as second subpixels, and in this case, the first subpixels may be designed to emit light beams of the same color or various colors.

[0080] For example, in some embodiments of the present disclosure, the display panel is designed with a luminance correction function. For example, if the subpixel G shown in FIG. 2 is the first subpixel, when the subpixel block G1 cannot emit light due to the intrusion of debris, the luminance of the emitted light of the subpixel block G2 is adjusted according to the luminance of the emitted light of the subpixel G, thereby adjusting the luminance of the subpixel G to the expected luminance.

[0081] For example, in the second direction, the physical configuration of the display substrate 10 includes the substrate 100, and the display function layer 200 and the separation structure 210 located on the substrate 100. The second direction may be parallel to the Z axis.

[0082] For example, the isolation structure 210 defines a plurality of isolation openings 202 , and the light emitting elements 220 are positioned within the isolation openings 202 .

[0083] The display function layer 200 includes a plurality of light-emitting elements 220, and each sub-pixel block is provided with at least one light-emitting element 220, i.e., the light-emitting element 220 is a physical structure of a sub-pixel and a sub-pixel block. The light-emitting element 220 includes a first electrode 221, a light-emitting function layer 223, and a second electrode 222 sequentially stacked on the substrate 100, and the first electrodes 221 corresponding to the sub-pixel blocks G1 and G2 located in the same sub-pixel G are electrically connected to each other directly or indirectly.

[0084] It should be noted that even a subpixel that does not include a subpixel block includes a light-emitting element 220 having the above structure.

[0085] For example, the light-emitting functional layer 223 may include a first common layer 2231, a light-emitting layer 2232, and a second common layer 2233, which are sequentially stacked on the anode. The first common layer 2231 may include a hole injection layer, a hole transport layer, an electron blocking layer, etc. The second common layer 2233 may include an electron injection layer, an electron transport layer, a hole blocking layer, etc. In the arrangement of the isolation structure 210, the first common layers (main film layers that cause current crosstalk) of each light-emitting element 220 need to be electrically isolated from each other.

[0086] In at least one embodiment of the present disclosure, the display area 11 includes a first display area 13, and the separation structure 210 can define a plurality of light-transmitting openings 201, which are located within the first display area 13, thereby enabling the first display area 13 of the display panel to allow light transmission.

[0087] In the above embodiment, the first electrodes 221 of the two light-emitting elements 220 in the same first subpixel are electrically connected to each other (either directly or indirectly), without changing the driving method of the entire pixel. Furthermore, the use of the isolation structure 210 eliminates the need for a mask plate in the manufacturing process of the light-emitting elements 220, eliminating the need to consider alignment accuracy issues during the manufacturing process. This reduces the gap size between the light-emitting elements 220 and is advantageous for increasing the pixel layout density (PPI) of the display panel (see the following examples related to the manufacturing method of the display panel for details). Furthermore, by providing a light-transmitting opening 201 in the isolation structure 210 in the first display region 13, light can be transmitted to the region of the display panel where the light-transmitting opening 201 is provided. This allows the first display region 13 of the display panel to realize transparent display or under-display identification functions, such as fingerprint identification and under-display photography.

[0088] In at least one embodiment of the present disclosure, the isolation structure 210 includes a support portion 211 and a crown portion 212 sequentially stacked on the substrate 100, the orthogonal projection of the support portion 211 onto the substrate 100 being located within the orthogonal projection of the crown portion 212 onto the substrate 100, the support portion 211 being a conductive structure, and the second electrode 222 of the light-emitting element 220 being located in the corresponding isolation opening 202 and connected to the support portion 211. In this manner, in the gap between adjacent light-emitting elements 220, the entire isolation structure 210 essentially has a shape that is wide at the top and narrow at the bottom, thereby increasing the blocking effect of the isolation structure 210 on the light-emitting functional layer 223 (including the first common layer 2231, which is a main film layer causing current crosstalk) during the manufacturing process of the light-emitting element 220, thereby reducing the problem of current crosstalk between adjacent light-emitting elements 220.

[0089] It should be noted that in some designs of the present disclosure, the support portion 211 and the crown portion 212 can be designed as a multi-layer laminated structure as shown in FIG. 5, and may be conveniently made of different materials, for example, in the following example, the support portion 211 is designed to be conductive, but the crown portion 212 is not limited to being designed to be conductive, or in some other designs of the present disclosure, the support portion 211 and the crown portion 212 may be provided as an integrated structure to increase the robustness of the separation structure 210.

[0090] 5, the support 211 may be a conductive structure, and the second electrode 222 is located in the isolation opening 202 and connected to the support 211. In this manner, the support 211 of the isolation structure 210 connects the second electrode 222 in series, so that the support 211 and the second electrode 222 form a common electrode to facilitate driving.

[0091] The material of the second electrode 222 may be a metal material, and the thinner the second electrode 222, the higher its light transmittance, but the higher its resistivity. If the second electrode 222 is too thin, the voltage drop of the second electrode 222 (in this case, the common electrode) will be too large if no isolation structure 210 is provided. In the embodiment of the present disclosure, the second electrode 222 is connected to the conductive support portion 211, which can remove the thickness restriction of the second electrode 222, and therefore the thickness of the second electrode 222 can be reduced, resulting in a higher light transmittance.

[0092] In at least one embodiment of the present disclosure, the support 211 may be a metal conductive structure, and the high conductivity of the metal material can reduce the voltage drop during cathode operation. Correspondingly, metal materials can transmit light only when they are extremely thin (e.g., on the order of several tens of nanometers), but the separation structure 210 requires a certain thickness to separate the light-emitting functional layer 223 (including the first common layer 2231). Correspondingly, the support 211 of the separation structure 210 is almost opaque to light. Therefore, the separation structure 210 can transmit light simply by providing the light-transmitting opening 201.

[0093] 5 and 6 , the display substrate may further include a pixel defining layer 213, which is located on one side of the isolation structure 210 closer to the substrate 100, i.e., the pixel defining layer 213 is located between the substrate 100 and the isolation structure 210, and the pixel defining layer 213 includes a plurality of pixel openings 203, each corresponding to the isolation opening 202. The pixel openings 203 position and define the light-emitting elements 220 and expose the first electrodes 221, and each pixel opening 203 corresponds to the isolation opening 202, and the pixel openings 203 are connected to the corresponding isolation openings 202.

[0094] When the light-emitting element 220 is activated with a low voltage, the brightness is low, which results in poor visual effect, and if there is leakage current, the light-emitting element 220 may emit light even at low gray levels (e.g., in a dark state), i.e., it cannot be turned off.

[0095] 7 , in at least one embodiment of the present disclosure, in a first subpixel, the orthogonal projections of pixel openings 203 corresponding to at least two subpixel blocks are located within the orthogonal projections of the same separation opening 202 onto the substrate 100. The pixel openings 203 corresponding to the subpixel blocks are pixel openings 203 in which the light-emitting elements 220 of the subpixel blocks are located. By separating the entire first subpixel by the separation structure 210, the light-emitting functional layers 223 of the subpixel blocks in the first subpixel are located within the same separation opening 202. This means that there is no need to provide the separation structure 210 between the subpixel blocks of the first subpixel, and the subpixel blocks are only separated from each other by the pixel defining layer 213, thereby reducing the overall difficulty of manufacturing the separation structure 210. In addition, the emission colors of the subpixel blocks in the same first subpixel are the same, and there is no problem of color mixing due to carrier crosstalk between the light-emitting functional layers 223 of the subpixel blocks. Therefore, even if the isolation structure 210 is not provided between each subpixel block of the same first subpixel, the light-emitting effect of the first subpixel can be ensured.

[0096] As shown in FIG. 3 , in at least one embodiment of the present disclosure, the orthogonal projection of the pixel opening 203 corresponding to each subpixel block onto the substrate 100 is located within the orthogonal projection of each isolation opening 202 onto the substrate 100. Each subpixel block is separated by an isolation structure 210, which directly separates the subpixel blocks. This eliminates the need for a separate mask plate to fabricate each subpixel block, thereby reducing costs. Furthermore, the isolation structure 210 has a good shielding effect, allowing the subpixel blocks to be spaced and insulated from each other without affecting the light-emitting functional layers 223 of each subpixel block. A first subpixel is divided into multiple independent subpixel blocks. If at least one of the subpixel blocks is damaged, causing a dark spot, the other subpixel blocks can continue to emit light normally, thereby ensuring normal light emission from the display panel. That is, the first subpixel is divided into multiple subpixel blocks, which can reduce the impact of a single dark spot on the display panel.

[0097] 5 and 6 , in at least one embodiment of the present disclosure, the orthogonal projection of the gap between two adjacent first electrodes 221 onto the substrate 100 is located within the orthogonal projection of the support 211 onto the substrate 100, such that the edge of the first electrode 221 overlaps with the edge of the support 211 to form a capacitor, and the pixel defining layer 213 covers the edge of the first electrode 221 to separate the support 211 from the first electrode 221. In this way, the capacitor formed by the edge portions of the support 211 and the first electrode 221 is charged during the turn-on phase of the light emitting element 220, thereby increasing the turn-on voltage of the light emitting element 220 and achieving a predetermined brightness requirement when the light emitting element 220 emits light; further, this design can also prevent the light emitting element 220 from emitting light at a low gray level.

[0098] For example, the pixel-defining layer 213 may be an inorganic layer. Because the inorganic layer is thin, a capacitor formed between the edge of the first electrode 221 and the edge of the support 211 has sufficient capacitance. In at least one embodiment of the present disclosure, the isolation structure 210 extends continuously between two adjacent subpixel blocks, thereby blocking light between the two adjacent subpixel blocks. The isolation structure 210 extends continuously between the adjacent subpixel blocks, thereby blocking light between the two adjacent subpixel blocks and avoiding the problem of stray light passing through the region between the adjacent subpixel blocks and reaching the light-emitting surface of the display panel, which may adversely affect the display effect of the display panel. Furthermore, the isolation structure 210 extends continuously, thereby increasing the distribution area of ​​the isolation structure 210. The isolation structure 210 may be made of a metal material or other reflective material. A larger area of ​​the isolation structure 210 can increase the amount of reflected light, further improving the luminance of the display panel.

[0099] Furthermore, the display panel has a touch function and can also take into consideration functions such as transparent display, under-display identification (fingerprint identification, under-display photography), etc. In this way, in the display panel, a light-transmitting area is partitioned and light-transmitting holes are provided in the gaps between the sub-pixels of the light-transmitting area to achieve light transmission. However, in the area where the light-transmitting holes are located, signal interference may occur between the conductive structure for achieving the touch function (e.g., the touch electrode described below) and the lower-layer driving circuit (e.g., the pixel driving circuit in the substrate described below), which may result in poor touch or display function.

[0100] 1 and 4 to 9B, the first display region 13 is provided with a light-transmitting aperture 201, and the subpixel G is the first subpixel, which is divided into two subpixel blocks G1 and G2 by the light-transmitting aperture 201. In this way, the light-transmitting aperture 201 allows the first display region 13 to have a certain light transmittance for under-display identification, photography, or transparent display. Note that in some embodiments of the present disclosure, the frame region 12 can be designed as a one-side frame by arranging some wires in the frame region 12 within the display region 11.

[0101] 1 and 4 to 9B, the display panel may further include a touch structure 20, which is located on the light-emitting side of the display substrate 10 and includes a touch electrode 400. The touch electrode 400 has a lattice structure, and the orthogonal projections of the lattice lines of the touch electrode 400 onto the display substrate 10 are located at the gaps between the subpixels (wherein all the subpixels may be first subpixels, and some of the subpixels may be first subpixels). In this way, in the region where the light-transmitting opening 201 is located, the lattice lines 21 of the touch electrode 400 surround the periphery of the light-transmitting opening 201, i.e., at least one side (three sides in FIG. 4) of the light-transmitting opening 201 and the lattice lines 21 are spaced apart by subpixels or subpixel blocks (e.g., subpixel blocks G1, G2). In this way, at the light-transmitting opening 201, the distance between the grid lines 21 of the touch electrode 400 and the driving circuit in the display substrate 10 is increased, thereby reducing the interference between the touch electrode 400 and the driving circuit.

[0102] In the embodiments of the present disclosure, the specific structure of the touch electrode is not limited and can be designed according to actual process needs. Different designs of the touch electrode will be described below through various embodiments, specifically as follows:

[0103] In at least one embodiment of the present disclosure, as shown in Figures 8A and 8B, the touch electrode 400 includes a plurality of parallel first electrode strips 410 and a plurality of parallel second electrode strips 420, the first electrode strips 410 and the second electrode strips 420 are spaced apart from each other and intersect with each other to form touch units at the intersections, and the first electrode strips 410 and the second electrode strips 420 are arranged in a grid-like electrode.

[0104] 8A and 8B, in some embodiments of the present disclosure, the first electrode strip 410 is located between the second electrode strip 420 and the isolation structure 210. Macroscopically, the intersecting and overlapping area of ​​the first electrode strip 410 and the second electrode strip 420 is the area where the touch unit is located, and in the overlapping area, the first electrode strip 410 and the second electrode strip 420 are both transparent. The first electrode strip 410 and the second electrode strip 420 can be separated by an insulating layer 430.

[0105] For example, in some other embodiments of the present disclosure, as shown in FIGS. 9A and 9B , a first electrode band 410 includes a plurality of spaced apart first electrode blocks 411 and a plurality of first connecting portions 412, and the plurality of first electrode blocks 411 of the same first electrode band 410 are connected by the first connecting portions 412; a second electrode band 420 includes a plurality of second electrode blocks 421 and a plurality of second connecting portions 422, and the plurality of second electrode blocks 421 of the same second electrode band 420 are connected by the first connecting portions 412; The second electrode blocks 421 are connected by second connecting portions 422, and the first connecting portions 412 and the second connecting portions 422 cross and are spaced apart, where the first electrode blocks 411, the first connecting portions 412, and the second electrode strips 420 are in the same layer, and the second connecting portions 422 are located between the first connecting portions 412 and the isolation structure 210, or the second connecting portions 422 are located on one side of the first connecting portions 412 away from the isolation structure 210. This design provides high light transmittance for the touch electrode 400, and high alignment accuracy between the mesh holes and the light-transmitting openings 201 and the isolation openings 202, thereby improving the light transmittance of the first display area 13. In this design, the main portions of the first electrode strips 410 and the second electrode strips 420 are designed in the same layer, which eliminates the need to consider alignment issues between the mesh holes and is advantageous for improving the light transmittance of the touch electrode 400. For example, the second connection portion 422 and the first connection portion 412 can be separated by an insulating layer 430 .

[0106] In the embodiments of the present disclosure, the types and numbers of sub-pixels provided with the sub-pixel blocks are not limited and can be selected according to the requirements of the actual process. Various situations will be presented below based on different embodiments.

[0107] For example, referring again to FIG. 4 , the subpixels included in each pixel are classified into a first subpixel R, a second subpixel G, and a third subpixel B that emit light of different colors, with the second subpixel G located between the first subpixels R. Note that the number of subpixels included in each pixel and the colors of emitted light can be designed according to actual process requirements, and the embodiments of the present disclosure are not limited thereto. For example, the color of emitted light of the first subpixel can be selected from at least one of red, green, and blue.

[0108] In some embodiments of the present disclosure, the subpixel located at the intermediate position in each pixel is designed to include a subpixel block, i.e., the first subpixel is a first-color subpixel that emits light of one color, and the first display area further includes a number of second-color subpixels and a number of third-color subpixels arranged in an array in a first direction, where each adjacent first-color subpixel, second-color subpixel, and third-color subpixel constitutes one pixel, and in each pixel, the first-color subpixel is located between the second-color subpixel and the third-color subpixel, the first-color subpixel, the second-color subpixel, and the third-color subpixel emit light of different colors, and the second-color subpixel and the third-color subpixel are both continuous structures. For example, optionally, the width of the first-color subpixel along the direction from the second-color subpixel to the third-color subpixel is equal to the width of the light-transmitting aperture. For example, optionally, the wavelengths of the emitted light of the second-color subpixel, the first-color subpixel, and the third-color subpixel sequentially decrease. For example, as shown in Figures 4 and 10, the second color subpixel, the first color subpixel, and the third color subpixel are subpixel R, subpixel G, and subpixel B, respectively, and the subpixel G is configured to include at least two subpixel blocks G1 and G2 separated by a light-transmitting aperture 201, and the subpixel R and the subpixel B are both continuous structures.

[0109] When subpixel G is designed to include subpixel blocks, the width of the light-transmitting aperture 201 corresponding to subpixel G can be designed depending on the presence or absence of surrounding grid lines 21. For example, as shown in FIG. 4 , when grid lines 21 are arranged in subpixel G, the width of subpixel G is larger than the width of the light-transmitting aperture 201 along the direction from subpixel R to subpixel B (the X-axis direction in FIG. 4 ). Alternatively, as shown in FIG. 10 , the light-transmitting aperture 201 is spaced apart from the grid lines 21 by subpixel blocks G1, G2, subpixel R, and subpixel B, so that it is not adjacent to the grid lines 21. The width of subpixel G is equal to the width of the light-transmitting aperture 201 along the direction from subpixel R to subpixel B. This allows the light-transmitting aperture 201 to have a large design area, thereby increasing the light transmittance of the first display region. Furthermore, the distance between the light-transmitting aperture 201 and the grid lines 21 is large, which significantly reduces the interference between the touch function and the display function during operation.

[0110] In the embodiments of the present disclosure, a "continuous structure" means that all parts of the planar shape of the target object are connected and have only one outer edge but no inner edges, i.e., the continuous structure does not surround an opening.

[0111] In some other embodiments of the present disclosure, in each pixel, at least two adjacent subpixels are designed to include a subpixel block, and at least one subpixel is designed to have a continuous structure, i.e., a first subpixel is classified into a first-color subpixel and a second-color subpixel, each emitting at least two different colored light beams, and the first display area may further include a number of third-color subpixels arranged in an array in a first direction, where each adjacent first-color subpixel, second-color subpixel, and third-color subpixel constitutes one pixel, and in each pixel, the second-color subpixel is located between the first-color subpixel and the third-color subpixel, and the third-color subpixel has a continuous structure. For example, in each pixel, the light-transmitting apertures corresponding to the first-color subpixel and the second-color subpixel are selectively connected to each other. For example, selectively, the distance from the light-transmitting aperture to the grid line on one side of the first-color subpixel away from the second-color subpixel is greater than the distance from the first-color subpixel to the grid line. 11 to 13, the first color subpixel, the second color subpixel, and the third color subpixel may have sequentially decreasing wavelengths of emitted light. For example, as shown in Figures 11 to 13, the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially subpixel R, subpixel G, and subpixel B, where subpixel R includes at least two subpixel blocks R1 and R2 separated by a light-transmitting aperture 201, subpixel G includes at least two subpixel blocks G1 and G2 separated by a light-transmitting aperture 201, and subpixel B has a continuous structure.

[0112] For example, when subpixel R and subpixel G are each configured to include two subpixel blocks, as shown in FIG. 12 , the side of the light-transmitting opening 201 adjacent to the grid line 21 is moved inward to increase the distance between the light-transmitting opening 201 and the grid line 21, i.e., on one side of subpixel R away from subpixel G, the distance from the light-transmitting opening 201 to the grid line 21 is greater than the distance from subpixel R to the grid line 21.

[0113] For example, when subpixel R and subpixel G each include two subpixel blocks, the adjacent light-transmitting apertures can be merged to increase the design area of ​​the light-transmitting aperture, and in each pixel, the light-transmitting apertures 201 corresponding to subpixel R and subpixel G are connected to each other, as shown in Fig. 12. In this way, the light-transmitting apertures 201 can have a large design area (the number of light-transmitting apertures 201 increases), thereby providing the first display region 13 with high light transmittance.

[0114] In some embodiments of the present disclosure, all subpixels in each pixel can be designed to include a subpixel block, i.e., a first subpixel is classified into a first-color subpixel, a second-color subpixel, and a third-color subpixel, each emitting light beams of at least three colors, and each adjacent first-color subpixel, second-color subpixel, and third-color subpixel constitutes one pixel, and in each pixel, the second-color subpixel is located between the first-color subpixel and the third-color subpixel. For example, in each pixel, the light-transmitting apertures corresponding to the first-color subpixel, the second-color subpixel, and the third-color subpixel can be selectively connected to each other. For example, selectively, the distance from the light-transmitting aperture to the grid line on one side of the first-color subpixel away from the second-color subpixel is greater than the distance from the first-color subpixel to the grid line, and the distance from the light-transmitting aperture to the grid line on one side of the third-color subpixel away from the second-color subpixel is greater than the distance from the third-color subpixel to the grid line. For example, the wavelengths of light emitted by the first color subpixels, the second color subpixels, and the third color subpixels may selectively decrease sequentially. For example, the first color subpixels, the second color subpixels, and the third color subpixels may selectively emit red light, green light, and blue light, respectively. For example, as shown in FIG. 14 , the first color subpixels, the second color subpixels, and the third color subpixels may sequentially be subpixels R, G, and B, respectively, and each of the subpixels R, G, and B may be arranged to include at least two subpixel blocks separated by a light-transmitting aperture 201. For example, in each pixel, the light-transmitting apertures 201 corresponding to the subpixels R, G, and B are connected to each other. For example, on one side of subpixel R away from subpixel G, the distance from the light-transmitting aperture 201 to the grid line is greater than the distance from subpixel R to grid line 21, and on one side of subpixel B away from subpixel G, the distance from the light-transmitting aperture 201 to the grid line 21 is greater than the distance from subpixel B to grid line 21.In this way, the light-transmitting openings 201 can have a larger design area (the number of light-transmitting openings 201 can be increased), so that the first display area 13 has a higher light transmittance; furthermore, this design makes the length between the light-transmitting openings 201 and the grid lines 21 shorter and the spacing between the adjacent positions larger, thereby reducing the problem of the touch function and the display function interfering with each other when driven.

[0115] For example, in at least one embodiment of the present disclosure, the wavelengths of the emitted light from subpixel R, subpixel G, and subpixel B sequentially decrease. In this manner, subpixel G is designed to emit light to which the human eye is sensitive. In this case, the design area required for subpixel G is relatively small, and when subpixel G is designed to include a subpixel block, the effect on the luminous efficiency of the pixel is reduced. For example, further optionally, subpixel R, subpixel G, and subpixel B can be designed to sequentially emit red light, green light, and blue light.

[0116] In the embodiments of the present disclosure, when the grid lines of the touch electrodes are located in the gaps between the subpixels, the specific positional relationship between the grid lines and the subpixels is not limited and can be designed according to the requirements of the actual process. Hereinafter, a description will be given of examples with reference to several specific embodiments.

[0117] For example, in some embodiments of the present disclosure, referring again to FIGS. 4 and 11 , the touch electrode includes a plurality of mesh holes surrounded by grid lines 21, where the mesh holes correspond one-to-one to the sub-pixels R, G, and B, and the sub-pixels R, G, and B are located within the orthogonal projections of the corresponding mesh holes onto the display substrate, i.e., the grid lines surround each sub-pixel R, G, and B.

[0118] For example, as shown in Figures 4 and 11, the centroids of the mesh holes projected orthogonally onto the display substrate are aligned with the centroids of the corresponding sub-pixels R, G, and B. This design can mitigate the brightness difference between the light beams emitted from the sub-pixels R, G, and B at the same viewing angle but in different directions, thereby reducing color shift.

[0119] For example, in some other embodiments of the present disclosure, referring again to Figures 10 and 12 to 14, the touch electrode includes a plurality of mesh-shaped holes surrounded by grid lines 21, the mesh holes correspond one-to-one to the pixels, and the pixels are located within the orthogonal projection of the corresponding mesh-shaped holes onto the display substrate, i.e., the grid lines 21 surround the pixels.

[0120] For example, as shown in Figures 10 and 12 to 14, the centroids of the mesh holes projected onto the display substrate are aligned with the centroids of the corresponding pixels, which can reduce the brightness difference between light rays emitted from sub-pixels at the same viewing angle and in different directions, thereby reducing color shift.

[0121] In the embodiment of the present disclosure, for the first sub-pixels in the sub-pixel block, the connection method of the first electrodes of the adjacent light-emitting elements therein is not limited.

[0122] 5, in at least one embodiment of the present disclosure, the substrate 100 includes a base and a driving circuit layer located on the base, the driving circuit layer including a plurality of pixel driving circuits located in the display area, and the display function layer is located on the driving circuit layer. For example, the pixel driving circuits include a plurality of transistors (TFTs), capacitors, etc., and can be formed in various forms, such as 2T1C (i.e., two transistors (TFTs) and one capacitor (C)), 3T1C, or 7T1C. The pixel driving circuits are connected to the light-emitting elements 220 to control the switching state and light-emitting brightness of the light-emitting elements 220.

[0123] 5 , in some embodiments of the present disclosure, the orthogonal projection of the first electrode 221 onto the substrate 100 is located outside the orthogonal projection of the light-transmitting opening 201 onto the substrate 100, the substrate 100 is provided with a conductive wire 101, and in a first subpixel having subpixel blocks, the first electrodes 221 of the light-emitting elements 220 corresponding to two adjacent subpixel blocks are connected to each other via the conductive wire 101. In this design, the first electrode 221 is disposed to avoid the light-transmitting opening 201, thereby increasing the light transmittance of the light-transmitting opening 201 of the display panel, and thereby increasing the light transmittance of the first display area 13. The width of the conductive wire 101 is narrow, and it is easy to dispose the first electrode 221 to avoid the light-transmitting opening 201 so as not to block light transmission through the light-transmitting opening 201.

[0124] 15 and 16 , the first electrode 221 includes a reflective electrode layer 2211 and a transparent electrode layer 2212 stacked on the substrate 100, the reflective electrode layer 2211 is located between the transparent electrode layers 2212, in a first subpixel having a subpixel block, the first electrodes 221 of the light-emitting elements 220 in the subpixel block are connected via the transparent electrode layer 2212, and the orthogonal projection of the light-transmitting aperture 201 onto the substrate 100 is located inside the orthogonal projection of the transparent electrode layer 2212 onto the substrate 100. With this design, the arrangement of the separation aperture 202 does not increase the difficulty of the manufacturing process of the display substrate and does not affect the arrangement of circuits within the substrate 100.

[0125] For example, the first electrode 221 may be an anode, and the second electrode 222 may be a cathode. The body material of the anode is a high work function material such as ITO or IGO, which has high light transmittance. In practical applications, the light emitting device 220 is designed as a top emission mode, so a reflective layer is provided on the anode to reflect light excited in the light emitting functional layer 223 to one side away from the anode. To ensure the conductivity of the anode, a highly reflective and conductive material such as a metal is used for the reflective layer.

[0126] 15 and 16 may be modified so that, in a first subpixel, light-emitting elements 220 corresponding to two adjacent subpixel blocks share the first electrode 221. For example, at the position where the light-transmitting aperture 201 is located, a via hole overlapping the light-transmitting aperture 201 may be disposed in the first electrode 221 so as not to block light entering the light-transmitting aperture 201. In this case, the orthogonal projection of the light-transmitting aperture 201 onto the substrate may be overlapped with the orthogonal projection of the via hole of the first electrode 221 onto the substrate, or the orthogonal projection of the light-transmitting aperture 201 onto the substrate may be located within the orthogonal projection of the via hole of the first electrode 221 onto the substrate.

[0127] 17, the display panel may further include a first encapsulation layer 310, which covers at least the light emitting elements 220 to protect the film layers of the light emitting elements 220 during the manufacturing process of the display panel. Note that the light emitting elements 220 emitting light of different colors are manufactured independently, but the film layers (deposited film layers such as the light emitting functional layer 223) of each light emitting element 220 are deposited over the entire surface of the display panel during deposition. For example, the light-emitting elements 220 are classified into light-emitting elements that emit red light (R), green light (G), and blue light (B), respectively. In the manufacturing process, the light-emitting elements R, G, and B are manufactured sequentially. When manufacturing the light-emitting element R, the light-emitting element R is formed in each separation opening 202. A first sealing layer 310 is manufactured in the display panel to cover the light-emitting element G. Next, the first sealing layer 310 in the separation opening 202 (used to form the light-emitting elements G and B in the final product) and the cathode and light-emitting functional layer 223 of the light-emitting element R are removed (the remaining part of the first sealing layer 310 is a sealing unit that covers the light-emitting element). In this process, the first sealing layer 310 is used to protect the light-emitting element R in the other separation opening. The light-emitting elements G and B are manufactured sequentially based on this method, and finally the first sealing layer 310 as shown in FIG. 5 is formed. Correspondingly, the first sealing layer 310 is composed of a sealing unit that covers each light-emitting element 220. In the above manufacturing process, the first sealing layer 310 in the light-transmitting opening 201 can be removed to further increase the light transmittance of the first display area.

[0128] In at least one embodiment of the present disclosure, referring again to FIG. 5 , the display panel may further include a second encapsulating layer 320 and a third encapsulating layer 330 covering the first encapsulating layer 310, the second encapsulating layer 320 being located between the first encapsulating layer 310 and the third encapsulating layer 330, the first encapsulating layer 310 and the third encapsulating layer 330 being inorganic layers that are highly dense to separate moisture and oxygen, and the second encapsulating layer 320 being an organic layer that has a large thickness to thereby planarize the surface of the display panel.

[0129] For example, as shown in FIG. 17, the display panel may further include structures such as an optical film sheet 500, a cover plate 600, etc., which may be located on one side of the touch structure away from the display substrate.

[0130] Hereinafter, with reference to Figures 18A, 18B, 19A, 19B, 20A, 20B, 21A, 21B, and 22, the manufacturing process of the display panel shown in Figures 5 and 6 will be described, and the principle of increasing the pixel arrangement density PPI by the isolation structure will be intuitively explained, where Figures 18A, 19A, 20A, and 21A correspond to the manufacturing process of the display panel shown in Figure 5, and Figures 18B, 19B, 20B, 21B, and 22 correspond to the manufacturing process of the display panel shown in Figure 6.

[0131] As shown in Figures 18A and 18B, a substrate 100 is provided, and first electrodes 221 arranged in an array are formed on the substrate 100. An insulating material film layer (e.g., an inorganic material film layer) is deposited on the substrate 100 on which the first electrodes are formed. A support portion 211 and a crown portion 212 are formed in the display panel, in which light-transmitting openings 201 and separation openings 202 are formed. The insulating material film layer is patterned to form a pixel definition layer 213 (having a lattice-like planar shape), which includes third via holes and covers the gaps between adjacent first electrodes. Thus, the pixel definition layer 213 has a lattice-like planar shape.

[0132] In the embodiment of the present disclosure, the patterning process is a photolithography patterning process, which may include, for example, coating a photoresist on the structural layer that needs to be patterned, exposing the photoresist using a mask plate, developing the exposed photoresist to obtain a photoresist pattern, etching (selectively wet etching or dry etching) the structural layer using the photoresist pattern, and then selectively removing the photoresist pattern. Note that if the material of the structural layer (e.g., the following photoresist pattern 700) includes photoresist, the structural layer can be directly exposed through a mask plate to form the required pattern.

[0133] 19A and 19B, a light-emitting functional layer and a second electrode are deposited on the substrate 100 to form a light-emitting element 220 in each light-transmitting opening 201 of the isolation structure 210. Since no mask plate is used in the deposition process, the deposited material is also deposited on the crown portion 212, and is also deposited on the light-transmitting opening 201 and the isolation opening 202. For example, the deposited light-emitting functional layer can emit red light (G), that is, at this stage, a light-emitting element 220 emitting red light is formed in each light-transmitting opening 201 and the isolation opening 202 of the isolation structure 210.

[0134] As shown in Figures 20A and 20B, a first encapsulating layer 310 is deposited to cover the light-emitting element 220, and at this stage the first encapsulating layer 310 covers the entire display area. A photoresist is formed on the first encapsulating layer 310 (e.g., by coating), and then patterned to form a photoresist pattern 700, which covers only a portion of the isolation opening 202 of the isolation structure 210 (the isolation opening 202 where the light-emitting element G of the display panel product is located).

[0135] As shown in Figures 21A and 21B, the photoresist pattern 700 is used as a mask to etch the surface of the display panel, removing the first sealing layer 310, the second electrode and the light-emitting functional layer covered by the photoresist pattern 700, and then removing the remaining photoresist pattern 700.

[0136] As shown in FIG. 22, the above steps are repeated to form light emitting elements 220 that emit green and blue light, respectively, in the other separated openings 202.

[0137] After all the light emitting elements 220 are manufactured, the second encapsulating layer 320 and the third encapsulating layer 330 are formed on the first encapsulating layer 310, respectively.

[0138] Referring again to FIGS. 5 and 6, the touch electrode 400 is fabricated on the third encapsulation layer 330 .

[0139] The manufacturing sequence of the light emitting elements 220 that emit red, green, and blue light can be designed according to actual needs, and the embodiments disclosed herein are not limited thereto.

[0140] In some embodiments of the present disclosure, some film layers of light-emitting functional layers such as light-emitting layers can be manufactured using a non-deposition method such as inkjet printing, and the specific method can be selected depending on the material of the film layer. For example, if the film layer is made of a polymer material and is not suitable for deposition, it can be manufactured using inkjet printing.

[0141] It should be noted that in the embodiments of the present disclosure, the design area of ​​the first display region is not limited and can be designed according to the actual process demands and application scenarios of the display panel.

[0142] For example, in some embodiments of the present disclosure, the entire display area can be designed as the first display area 13. With this design, the display panel can be used for scenes such as transparent display.

[0143] 1, for example, in some other embodiments of the present disclosure, the display area further includes a second display area (an area inside the display area 11 and outside the first display area 13), the second display area is located on at least one side of the first display area 13, the first display area 13 is a light-transmitting area, and the second display area is a non-light-transmitting area. With this design, the display panel can be used for scenarios such as fingerprint recognition or under-display photography.

[0144] In at least one embodiment of the present disclosure, the first subpixels include a first color subpixel, a second color subpixel, and a third color subpixel that are spaced apart from each other and have different colors, and the first color subpixel, the second color subpixel, and the third color subpixel are adjacently arranged. For example, the first color subpixel, the second color subpixel, and the third color subpixel selectively emit red light, green light, and blue light sequentially. For example, the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel R, subpixel G, and subpixel B, or the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel R, subpixel B, and subpixel G, and the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel G, subpixel R, and subpixel B, or the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel G, subpixel B, and subpixel R, or the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel B, subpixel G, and subpixel R, or the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel B, subpixel R, and subpixel G. In this specification, the first color subpixel, the second color subpixel, and the third color subpixel may be sequentially arranged as subpixel R, subpixel G, and subpixel B. As shown in FIG. 23 , in at least one embodiment of the present disclosure, a second-color subpixel G (e.g., subpixel blocks G1 and G2) is located on one side of a first-color subpixel R (e.g., subpixel blocks R1 and R2) in the second direction, and a third-color subpixel B (e.g., subpixel blocks B1 and B2) is located on one side of the first-color subpixel in the first direction, and the first direction and the second direction intersect. That is, the first-color subpixel, the second-color subpixel, and the third-color subpixel are arranged around each other. For example, optionally, the first-color subpixel and the second-color subpixel are located on one side of the third-color subpixel in the second direction.Here, the first direction is a direction parallel to the X axis, and the second direction is a direction parallel to the Y axis.

[0145] In at least one embodiment of the present disclosure, the first-color subpixels R and the second-color subpixels G have the same length in the first direction and both sides are flush with each other, forming a rectangular structure. Since the first-color subpixels R and the second-color subpixels G have the same length in the first direction, the light-emitting sizes of the first-color subpixels R and the second-color subpixels G in the first direction are similar, resulting in a good light-emitting effect. Furthermore, the both sides of the first-color subpixels R and the second-color subpixels G in the first direction are flush with each other, forming a single rectangular structure, which allows the first-color subpixels R and the second-color subpixels G to be aligned, thereby improving display uniformity. The first-color subpixels R and the second-color subpixels G form a single rectangular structure, i.e., the outer contours of the first-color subpixels R and the second-color subpixels R are extended and connected to form a single rectangular structure, which allows the alignment to be relatively uniform, further improving the display effect of the display panel.

[0146] Optionally, in the first direction, the first color subpixel R, the second color subpixel G, and the third color subpixel B have the same length, and the light-emitting sizes of the first color subpixel, the second color subpixel, and the third color subpixel in the first direction are similar, which further improves the light-emitting effect of the display panel.

[0147] Optionally, in the second direction, the first color subpixel R and the second color subpixel G have the same length, and the luminous sizes of the first color subpixel and the second color subpixel in the second direction are similar, which further improves the luminous effect of the display panel.

[0148] 24 , in at least one embodiment of the present disclosure, the first-color subpixels R (e.g., subpixel blocks R1 and R2), the second-color subpixels G (e.g., subpixel blocks G1 and G2), and the third-color subpixels B (e.g., subpixel blocks B1 and B2) are arranged in long strips and spaced apart sequentially in a first direction. This simple arrangement reduces manufacturing difficulties and facilitates the manufacture of the first-color subpixels, the second-color subpixels, and the third-color subpixels. Furthermore, this arrangement is relatively regular, which can improve the display uniformity of the display panel.

[0149] In at least one embodiment of the present disclosure, in a second direction intersecting the first direction, the first color subpixels, the second color subpixels, and the third color subpixels have the same length and both sides are flush with each other, forming a rectangular structure, so that the light-emitting sizes of the first color subpixels, the second color subpixels, and the third color subpixels are similar in the second direction, which further improves the display effect of the display panel. The first color subpixels, the second color subpixels, and the third color subpixels form a rectangular structure, i.e., the outer contours of the first color subpixels, the second color subpixels, and the third color subpixels can be extended and connected to form a rectangular structure, which is arranged in a relatively aligned manner, further improving the display effect of the display panel.

[0150] 25, in at least one embodiment of the present disclosure, a first subpixel includes at least three subpixel blocks (e.g., pixel blocks G1, G2, and G3), and the subpixel blocks are arranged peripherally, i.e., the subpixels are not arranged in the same direction but are arranged crosswise, and the subpixel blocks are arranged around a single center. For example, the first subpixel optionally has at least one subpixel block on one side of the same subpixel block in the first direction and the second direction.

[0151] 22 and 23 , in at least one embodiment of the present disclosure, the isolation structures 210 extend along the first and second directions (the gray-shaded portions in FIG. 25 can be considered to be the isolation structures 210), and first subpixels are spaced apart by the isolation structures 210 to form subpixel blocks adjacent in the first direction and / or subpixel blocks adjacent in the second direction. When the subpixel blocks are manufactured by disposing the isolation structures 210 and forming isolation openings 202 corresponding to each subpixel block, the light-emitting functional layers 223 of each subpixel block are separated by the isolation structures 210 and deposited in each separation opening 202, thereby forming subpixel blocks separated from each other in the first and second directions. The isolation structures 210 are arranged to provide a good separation effect between the subpixel blocks and reduce mutual influence between the subpixel blocks. If a dark spot problem occurs in one of the subpixel blocks, the other subpixel blocks continue to emit light normally, thereby ensuring the normal emission of the display panel, i.e., the first subpixel is divided into multiple subpixel blocks by the isolation structure 210, which can reduce the impact of a single dark spot defect on the display effect of the display panel. For example, if a dark spot problem occurs in pixel block R1 in Figure 25, pixel blocks R2, R3, and R4 can maintain normal emission, thereby ensuring the normal emission of the first color subpixels.

[0152] 24 and 25 , in at least one embodiment of the present disclosure, a first color subpixel includes a subpixel blocks, a second color subpixel includes b subpixel blocks, and a third color subpixel includes c subpixel blocks, where a, b, and c satisfy a≧b≧c. When the first color subpixel, the second color subpixel, and the third color subpixel are all divided into multiple subpixel blocks as shown in FIG. 24 , the first color subpixel, the second color subpixel, and the third color subpixel have an equal number of subpixels and a regular number distribution, which improves the display uniformity of the display panel, and the isolation structures 210 are arranged more regularly, which reduces the difficulty of manufacturing the isolation structures 210. As shown in FIG. 25 , when a>b, that is, the number of subpixel blocks of a first color subpixel (e.g., subpixel blocks R1, R2, R3, R4) is greater than the number of subpixel blocks of a second color subpixel (e.g., subpixel blocks G1, G2, G3), for example, a first color subpixel includes four subpixel blocks, a second color subpixel includes three subpixel blocks, and a third color subpixel includes two subpixel blocks, the number of subpixel blocks of a first color subpixel is greater and the area of ​​a single subpixel block is smaller. If at least one single subpixel block among them has a dark spot problem, the other subpixel blocks will emit light normally and have a larger light-emitting area, i.e., the first color subpixel will have a larger aperture ratio, thereby alleviating the effect of a single dark spot on the display panel.If the first color subpixels are fabricated after the second color subpixels, the first color subpixels are more likely to suffer from dark spots. Therefore, the first color subpixels are divided into more subpixel blocks to further reduce the effect of dark spots on the display performance. That is, the first subpixels fabricated later are divided into more subpixel blocks, thereby balancing the effect of dark spots on the first subpixels of each color and ensuring the display performance of the entire display panel. The second color subpixels and the third color subpixels have the same structures and effects as the first color subpixels and the second color subpixels, and therefore will not be described again here.

[0153] In at least one embodiment of the present disclosure, a first subpixel includes two subpixel blocks (subpixel blocks B1 and B2 in FIG. 25 ), which are spaced apart along a first direction. The first subpixel is divided into the spaced-apart subpixel blocks to reduce the luminous effect of a single dark spot on the entire first subpixel. For example, optionally, in the second direction, the two subpixel blocks have the same length and are flush with each other to form a rectangular structure. The luminous sizes of the two subpixel blocks in the second direction are similar, further improving the luminous effect of the first subpixel. The two subpixel blocks form a rectangular structure, i.e., the outer contours of the two subpixel blocks can be extended and connected to form a rectangular structure, which is relatively aligned and further improves the luminous effect of the first subpixel.

[0154] In at least one embodiment of the present disclosure, a first subpixel includes a first subpixel block, a second subpixel block, and a third subpixel block. For example, in FIG. 25 , subpixel block G1 is the first subpixel block, subpixel block G2 is the second subpixel block, and subpixel block G3 is the third subpixel block, where the first subpixel block and the second subpixel block are located on one side of the third subpixel block in a first direction and are spaced apart in a second direction. That is, the first subpixel includes three subpixel blocks, where the first subpixel block, the second subpixel block, and the third subpixel block are not arranged in the same direction but are arranged crosswise, and where the first subpixel block, the second subpixel block, and the third subpixel block are arranged around a single center.

[0155] Optionally, in the first direction, the first sub-pixel block and the second sub-pixel block have the same length and both sides are flush with each other to form a rectangular structure, so that the luminous sizes of the first sub-pixel block and the second sub-pixel block in the first direction are similar, which further improves the luminous effect of the first sub-pixel. The first sub-pixel block and the second sub-pixel block form a rectangular structure, i.e., the outer contours of the first sub-pixel block and the second sub-pixel block can be extended and connected to form a rectangular structure, which is arranged in a relatively regular manner, which further improves the luminous effect of the first sub-pixel.

[0156] Optionally, in the first direction, the first subpixel block, the second subpixel block and the third subpixel block have the same length, so that the luminous sizes of the first subpixel block, the second subpixel block and the third subpixel block in the first direction are similar, which further improves the luminous effect of the first subpixel.

[0157] Optionally, in the second direction, a side of the first subpixel block away from the second subpixel block is flush with one side of the third subpixel block, and the arrangement is relatively aligned, further improving the light-emitting effect of the first subpixel.

[0158] Optionally, in the second direction, a side of the second subpixel block away from the first subpixel block is flush with one side of the third subpixel block, and the arrangement is relatively aligned, further improving the light-emitting effect of the first subpixel.

[0159] In at least one embodiment of the present disclosure, a first subpixel includes four subpixel blocks (e.g., subpixel blocks R1, R2, R3, and R4 in FIG. 25), which are arranged peripherally, i.e., the four subpixel blocks are not arranged in the same direction but are arranged crosswise, and the four subpixel blocks are arranged around one center. For example, each side of one subpixel block in the first direction and the second direction has one subpixel block, and the four subpixel blocks are arranged in an array in the first direction and the second direction.

[0160] Optionally, at least two adjacent sub-pixel blocks in the first direction and / or the second direction have the same length and both sides are flush with each other to form a rectangular structure, so that the luminous sizes of each sub-pixel block in the first direction and the second direction are similar and the luminous effect of the first sub-pixel is further improved. The first sub-pixel block and the second sub-pixel block form a rectangular structure, i.e., the outer contours of the first sub-pixel block and the second sub-pixel block can be extended and connected to form a rectangular structure, so that the arrangement is relatively aligned and the luminous effect of the first sub-pixel is further improved.

[0161] In at least one embodiment of the present disclosure, in a first subpixel, at least two subpixel blocks have the same size of orthogonal projection onto the substrate 100, so that the luminous sizes of the subpixel blocks in the first subpixel are similar, thereby further improving the luminous effect of the first subpixel. The orthogonal projection of two subpixel blocks having the same size on the substrate 100 refers to the two subpixel blocks having the same shape and the same size in the first and second directions. For example, the orthogonal projection of one subpixel block on the substrate 100 is obtained by translating or rotating the orthogonal projection of another subpixel block on the substrate 100.

[0162] Optionally, the first sub-pixel includes 2n sub-pixel blocks, where n is a positive integer, and the size of the orthogonal projection of each sub-pixel block onto the substrate 100 is the same, i.e., the first sub-pixel is divided into an even number of sub-pixel blocks, and the luminous size of each sub-pixel block is similar, which further improves the luminous effect of the first sub-pixel.

[0163] Optionally, the size of the orthogonal projection onto the substrate 100 of at least one subpixel block of a first color subpixel and one subpixel block of a second color subpixel is the same, and the luminous sizes of the subpixel block in the first color subpixel and the subpixel block in the second color subpixel are similar, thereby improving the luminous uniformity of the first color subpixel and the second color subpixel.

[0164] In at least one embodiment of the present disclosure, the orthogonal projection of the first subpixel onto the substrate 100 is a polygon, the polygon having a plurality of corner regions, and a subpixel block being provided in at least one corner region. For example, the orthogonal projection of the first subpixel onto the substrate 100 is a rectangle, the rectangle having four corner regions, and at least one subpixel block being located in one corner region. Optionally, the first subpixel includes three subpixel blocks, where two subpixel blocks are located in two corner regions respectively, and another subpixel block is located across the other two corner regions. Optionally, the first subpixel includes four subpixel blocks, where the four subpixel blocks are located in the four corner regions respectively. The subpixel blocks being located in the corner regions can improve the light-emitting effect of the first subpixel, thereby improving the display effect of the display panel.

[0165] As shown in Figures 25 and 26, optionally, the edges of the subpixel blocks when orthogonally projected onto the substrate 100 may include straight edges and / or curved edges; for example, as shown in Figure 25, the edges of the subpixel blocks when orthogonally projected onto the substrate 100 may all be straight edges, or the edges of the subpixel blocks when orthogonally projected onto the substrate 100 may all be curved edges, or as shown in Figure 26, the edges of the subpixel blocks when orthogonally projected onto the substrate 100 may be a combination of straight edges and curved edges.

[0166] Optionally, the at least two straight edges are perpendicular to each other to form a right angle, and the subpixel block has a right angle, so that the outer contour of the first subpixel has a right angle, and the first subpixel having a right angle is less difficult to manufacture and has a good light-emitting effect.

[0167] As shown in FIG. 26, optionally, in at least two adjacent subpixel blocks, the right angles of the two subpixel blocks are spaced apart from each other, so that the right angles of the subpixel blocks are all located on the outer contours, i.e., the outer contour of the first subpixel has a right angle, so that the first subpixel is less difficult to manufacture and has a good light-emitting effect.

[0168] 27 , at least one embodiment of the present disclosure provides a display panel, the display panel including a first display region including a number of first subpixels arranged in an array in a first direction, each of the first subpixels including at least two subpixel blocks spaced apart from each other, the display panel further including a pixel defining layer 213, the pixel defining layer 213 being located on one side of a substrate 100 and including a plurality of pixel openings 203, the light-emitting elements 220 of the subpixel blocks being located within the pixel openings 203, the first subpixel having at least two adjacent subpixel blocks spaced apart by the pixel defining layer 213. By dividing the first subpixel into a plurality of subpixel blocks in the display panel, only a specific subpixel block will suffer from light emission failure due to debris, and the first subpixel itself can still emit light, thereby reducing the risk of harmful substances such as debris entering the subpixels and causing a malfunction of the display panel. Additionally, because the first sub-pixels are divided by the pixel defining layer 213 to form a plurality of spaced apart sub-pixel blocks, there is no need to provide the isolation structure 210, simplifying the manufacturing process.

[0169] Continuing to refer to FIG. 3, in at least one embodiment of the present disclosure, the display panel further includes an isolation structure 210 located on one side of the pixel definition layer 213 away from the substrate and defining a plurality of isolation openings 202, the light-emitting elements 220 of the sub-pixel blocks are positioned within the isolation openings 202, the pixel openings 203 correspond to the isolation openings 202, and the pixel openings 203 are connected to the corresponding isolation openings 202.

[0170] In at least one embodiment of the present disclosure, in a first subpixel, at least two subpixel blocks are adjacent to each other, and the two adjacent subpixel blocks are spaced apart by an isolation structure 210. The pixel defining layer 213 and the isolation structure 210 are used together to separate the first subpixel, which improves the spacing effect of the first subpixel and makes it less likely that the adjacent subpixel blocks will affect each other.

[0171] 7 , in at least one embodiment of the present disclosure, in a first subpixel, the orthogonal projections of pixel openings 203 corresponding to at least two subpixel blocks are located within the orthogonal projections of the same separation opening 202 onto the substrate 100, and the pixel openings 203 corresponding to the subpixel blocks are pixel openings 203 in which the light-emitting elements 220 of the subpixel blocks are located. By separating the entire first subpixel via the separation structure 210, the light-emitting functional layers 223 of the subpixel blocks within the first subpixel are located within the same separation opening 202. That is, the subpixel blocks within the first subpixel are only separated from each other by the pixel defining layer 213, without the need for the separation structure 210, thereby reducing the overall difficulty of manufacturing the separation structure 210. Furthermore, the subpixel blocks within the same first subpixel emit the same light, and color mixing problems due to carrier crosstalk do not occur between the light-emitting functional layers 223 of the subpixel blocks. Therefore, even if the isolation structure 210 is not provided between each subpixel block in the same first subpixel, the light emitting effect of the first subpixel can be ensured.

[0172] Continuing to refer to FIG. 3 , in at least one embodiment of the present disclosure, the orthogonal projection of the pixel opening 203 corresponding to each subpixel block onto the substrate 100 is located within the orthogonal projection of each isolation opening 202 onto the substrate 100. Each subpixel block is separated by an isolation structure 210, which is directly used to isolate each subpixel block. This eliminates the need for a separate mask plate and reduces manufacturing costs. Furthermore, the isolation structure 210 provides a better partitioning effect, allowing the light-emitting functional layers 223 of each subpixel block to be spaced apart and insulated without affecting each other. A first subpixel is divided into multiple independent subpixel blocks. If at least one of the subpixel blocks is damaged, causing a dark spot, the other subpixel blocks can continue to emit light normally, thereby ensuring normal light emission from the display panel. That is, dividing the first subpixel into multiple subpixel blocks can alleviate the impact of a single dark spot defect on the display panel.

[0173] At least one embodiment of the present disclosure may provide a display device including the display panel of the above embodiment. Furthermore, when the first display area is the identification area, the display device may include a photosensitive element, and an orthogonal projection of the photosensitive element onto the substrate at least partially overlaps with the first display area.

[0174] For example, in some embodiments of the present disclosure, the photosensitive element includes at least one fingerprint identification sensor, which can be provided on one side of the substrate away from the display function layer, or the fingerprint identification sensor can be provided within the substrate.

[0175] For example, in some other embodiments of the present disclosure, the photosensitive element may be a camera, and the camera is located on one side of the substrate away from the display function layer.

[0176] For example, in the embodiments of the present disclosure, the display device may be a product or part having a display function, such as a television, a digital camera, a mobile phone, a watch, a tablet computer, a laptop computer, or a navigator.

[0177] As shown in FIG. 28, with reference to FIGS. 1 to 27, at least one embodiment of the present disclosure provides a method for manufacturing a display panel, wherein the display panel includes a first display area, the first display area includes a number of first subpixels arranged in an array in a first direction, the first subpixels include at least two subpixel blocks, and the manufacturing method includes the following steps:

[0178] Step S01: sequentially fabricating a first electrode and a pixel definition layer on a substrate, the pixel definition layer including a plurality of pixel openings, the pixel openings defining the positions of the light-emitting elements and exposing the first electrode.

[0179] Step S02: Fabricating an isolation structure on one side of the pixel definition layer away from the substrate, the isolation structure defining a plurality of isolation openings, the pixel openings and the isolation openings corresponding to and communicating with each other.

[0180] Step S03: Sequentially fabricate a light-emitting functional layer and a second electrode on one side of the isolation structure away from the substrate, and the first electrode, the light-emitting functional layer, and the second electrode sequentially stacked on the substrate form a light-emitting element of the sub-pixel block.

[0181] Here, in the first sub-pixel, at least two sub-pixel blocks are adjacent to each other, and the adjacent two sub-pixel blocks are spaced apart by an isolation structure.

[0182] In these embodiments, step S01 fabricates the first electrode 221 and the pixel-defining layer 213. Step S02 fabricates the isolation structure 210. Step S03 fabricates the light-emitting functional layer 223 and the second electrode 222, where the first electrode 221, the light-emitting functional layer 223, and the second electrode 222 form the light-emitting element 220 of a subpixel block. Each subpixel block is separated by the isolation structure 210, which is directly used to divide the subpixel blocks. This eliminates the need for a separate mask plate and reduces costs. Furthermore, the isolation structure 210 provides a better partitioning effect, allowing the light-emitting functional layers 223 of each subpixel block to be spaced apart and insulated from one another without affecting each other. The first subpixel is divided into multiple independent subpixel blocks, and if at least one of the subpixel blocks is damaged and causes a dark spot problem, the other subpixel blocks can continue to emit light normally, thereby ensuring the normal emission of the display panel; that is, the first subpixel is divided into multiple subpixel blocks, which can alleviate the impact of a single dark spot defect on the display panel.

[0183] In at least one embodiment of the present disclosure, the first display area further includes a number of second-color subpixels and a number of third-color subpixels arranged in an array in a first direction, and adjacent first-color subpixels, second-color subpixels, and third-color subpixels constitute one pixel, and the manufacturing method further includes the following steps: fabricating a light-emitting element 220 of the first-color subpixel on the substrate 100, where the first-color subpixel includes a number of subpixel blocks; and fabricating a light-emitting element 220 of the second-color subpixel on the substrate 100, where the second-color subpixel includes b number of subpixel blocks, where a and b satisfy a>b.

[0184] In these embodiments, when the first color subpixels, the second color subpixels, and the third color subpixels are all divided into multiple subpixel blocks, the numbers of the first color subpixels, the second color subpixels, and the third color subpixels are equal and have a regular distribution, which improves the display uniformity of the display panel, and the arrangement of the isolation structures 210 is relatively regular, which reduces the difficulty of manufacturing the isolation structures 210. When a>b, that is, the number of subpixel blocks of a first color subpixel is greater than the number of subpixel blocks of a second color subpixel, for example, a first color subpixel includes four subpixel blocks, a second color subpixel includes three subpixel blocks, and a third color subpixel includes two subpixel blocks. The more subpixel blocks of a first color subpixel, the smaller the area of ​​a single subpixel block. If at least one single subpixel block has a dark spot problem, the other subpixel blocks will emit light normally and have a larger light-emitting area, that is, the first color subpixel will have a larger aperture ratio, thereby alleviating the effect of a single dark spot on the display panel. If the manufacturing order of the first color subpixels is after the deposition order of the second color subpixels, the first color subpixels are more likely to suffer from dark spots. Therefore, the first color subpixels are divided into a larger number of subpixel blocks to further reduce the impact of the dark spots on the display performance. That is, the later the manufacturing order, the more subpixels the first color subpixels are divided into, thereby balancing the impact of dark spots on the first color subpixels and ensuring the display performance of the entire display panel.

[0185] In at least one embodiment of the present disclosure, after the step of fabricating the light-emitting element 220 of the second color subpixel on the substrate 100, the manufacturing method further includes the step of fabricating the light-emitting element 220 of the third color subpixel on the substrate 100, where the third color subpixel includes c subpixel blocks, where b and c satisfy b>c.

[0186] In these embodiments, the structures and effects of the second color subpixel and the third color subpixel are similar to those of the first color subpixel and the second color subpixel, and the description will not be repeated here. For example, the first color subpixel, the second color subpixel and the third color subpixel are subpixel R, subpixel G and subpixel B in sequence, or the first color subpixel, the second color subpixel and the third color subpixel are subpixel R, subpixel B and subpixel G in sequence, or the first color subpixel, the second color subpixel and the third color subpixel are subpixel R, subpixel B and subpixel G in sequence, or the first color subpixel, the second color subpixel and the The subpixels of the first color, the second color, and the third color are successively subpixels G, R, and B, or the subpixels of the first color, the second color, and the third color are successively subpixels G, B, and R, or the subpixels of the first color, the second color, and the third color are successively subpixels B, G, and R, or the subpixels of the first color, the second color, and the third color are successively subpixels B, R, and G.

[0187] The above is merely a preferred embodiment of the present specification and is not intended to limit the present specification, and any modifications, equivalent replacements, etc. made within the spirit and principles of the present specification shall all be included in the protection scope of the present specification.
