Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a filter assembly, a display panel and an electronic device. Background Art

[0002] The display panel relies on the diaphragm layer to adjust the color or distribution of light to ensure the image effect. However, in order to cope with the thermal expansion of the diaphragm layer caused by temperature changes, space needs to be left between the diaphragm layer and the plastic frame to prevent expansion from affecting the life of the display panel. This causes some light to enter this space directly without mixing, which in turn affects the color performance of the light after passing through the edge area of ​​the filter. For example, some colors of light are directly emitted through the edge area without mixing, which causes the color to be oversaturated, ultimately reducing the image quality and viewing experience.

[0045] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0047] The light-emitting diode (LED) display panel includes a backlight source and a filter assembly disposed on a substrate. The light emitted by the light-emitting element in the backlight source is processed by the film layer (diffusion film, quantum dot film, dispersion film, etc.) in the backlight source, passes through the substrate, and is filtered by the filter assembly to form a rich color combination, and finally presents the required image information.

[0048] In actual design, since the diaphragm layer in the backlight source will expand with temperature changes, in order to prevent the expansion of the diaphragm layer from affecting its service life, a certain space will be reserved between the diaphragm layer of the backlight source and the rubber frame of the backlight source. This causes part of the light emitted by the light-emitting component to directly pass through the expansion space without being effectively mixed by the quantum dot film. It eventually reaches the edge area of ​​the filter assembly through refraction and reflection of other diaphragms, causing the color of the corresponding edge area of ​​the filter assembly to be oversaturated.

[0049] At present, the problem of oversaturation of the color at the edge area of ​​the filter assembly is solved by improving the structure of the backlight source. First, the plastic frame of the backlight source is painted to reduce the reflection ratio of the light entering the expansion space. Although this design can reduce the saturation of the edge area to a certain extent, the leakage and reflection of light cannot be avoided, and the edge area of ​​the filter assembly will still be oversaturated; second, a shading part is set on the side of the backlight source, but when the display panel is applied to a narrow-frame electronic device [such as a sub-millimeter light-emitting diode (Mini Light-Emitting Diode, MiniLED), whose frame is less than or equal to 2.5mm], there is no space to design the light-emitting part in the backlight source to be large enough to make the darkened area outside the display area, so the edge area of ​​the filter assembly will still have a high color saturation.

[0050] In view of the above technical problems, the present application provides a filter assembly 100. The filter assembly 100 of the present application can be applied to display panels, such as liquid crystal displays, organic light-emitting diode displays, etc., to achieve color management and improve image quality; it can also be applied to stage lighting to adjust the color effect of the lighting and create a specific atmosphere.

[0051] Example 1

[0052] like Figure 1 and Figure 2 As shown, Embodiment 1 of the present application provides a filter assembly 100, including:

[0053] A first color resist portion 1 located in the edge area;

[0054] A second color resist portion 2, adjacent to the first color resist portion 1;

[0055] Wherein, when the filter assembly 100 is applied to a display panel, the color saturation of the light emitted by the display panel after passing through the first color resist portion 1 is less than the saturation of the light after passing through the second color resist portion 2 .

[0056] The position of the first color resist portion 1 can be flexibly designed according to the specific position and range of the color enhancement at the edge of the filter assembly 100. For example, when the color of a portion of the edge area of ​​the filter assembly 100 is enhanced, the first color resist portion 1 can be located in the portion of the edge area; when the color of all edge areas of the filter assembly 100 is enhanced, the first color resist portion 1 can be located in all edge areas. By making the saturation of the first color resist portion 1 less than the saturation of the second color resist portion 2, the edge area of ​​the filter assembly 100 with excessive color enhancement is neutralized, thereby ensuring that the color of the overall transmitted light is more balanced and consistent, significantly improving the user's visual experience, and ensuring that the user can get a more natural and comfortable picture effect.

[0057] The position of the second color resist portion 2 can be arranged based on the position of the first color resist portion 1, and it plays a role of complementation and connection. When the first color resist portion 1 is located in part of the edge area, the second color resist portion 2 can be located in the remaining edge area and the middle area; when the first color resist portion 1 is located in the entire edge area, the second color resist portion 2 can be located in the middle area. The second color resist portion 2 can be adjacent to the first color resist portion 1 to achieve uniformity of the overall color presented in the end.

[0058] The first color resist portion 1 and the second color resist portion 2 may be formed by different masks. For example, the first color resist portion 1 is formed by a first mask, the first mask has a first area, the first area is used to face the second color resist portion 2 to shield the second color resist portion 2; the edge of the first mask has a second area, the second area is used to face the first color resist portion 1 to form the first color resist portion 1.

[0059] The first color resist portion 1 is formed by a second mask plate, and the edge of the second mask plate has a third area, which is used to face the first color resist portion 1 to block the first color resist portion 1; the second mask plate has a second area, and the second area is used to face the second color resist portion 2 to form the second color resist portion 2.

[0060] The filter assembly 100 provided in the present application includes a first color resist portion 1 located in the edge area, and a second color resist portion 2 adjacent to the first color resist portion 1. Since the saturation of the first color resist portion 1 is less than the saturation of the second color resist portion 2, this differentiated design neutralizes the excessive enhancement of the edge color of the filter assembly 100 caused by expansion space or other process factors, making the overall color of the light after passing through the filter assembly 100 more balanced and consistent, thereby improving the image quality and optimizing the user's visual experience.

[0061] Example 2

[0062] like Figure 3 and Figure 4 As shown, Embodiment 2 of the present application provides a filter assembly 100. The difference between the filter assembly 100 of Embodiment 2 and Embodiment 1 is that:

[0063] The first color resist portion 1 includes a plurality of first sub-color resist portions 11 of different colors, and the second color resist portion 2 includes a plurality of second sub-color resist portions 21 of different colors;

[0064] The color saturation of the light after passing through the first sub-color resist portion 11 of at least one color in the first color resist portion 1 is less than the color saturation of the light after passing through the second sub-color resist portion 21 of the same color in the second color resist portion 2 .

[0065] The first color resistance portion 1 may include first sub-color resistance portions 11 of various different colors such as red, blue, green, cyan, and yellow, and the second color resistance portion 2 may include second sub-color resistance portions 21 of various different colors such as red, blue, green, cyan, and yellow.

[0066] When a certain color is over-enhanced at the edge of the optical filter assembly 100, the saturation of the first sub-color resist portion 11 of the corresponding color will be designed to be smaller than the saturation of the second sub-color resist portion 21 of the corresponding color. For example, when the edge of the optical filter assembly 100 is blue-enhanced, the saturation of the blue first sub-color resist portion 11 in the first color resist portion 1 is smaller than the saturation of the blue second sub-color resist portion 21 in the second color resist portion 2; when the edge of the optical filter assembly 100 is red-enhanced, the saturation of the red first sub-color resist portion 11 in the first color resist portion 1 is smaller than the saturation of the red second sub-color resist portion 21 in the second color resist portion 2; when the edge of the first optical filter assembly 100 is green-enhanced, the saturation of the green first sub-color resist portion 11 in the first color resist portion 1 is smaller than the saturation of the blue and green second sub-color resist portion 21 in the second color resist portion 2, and so on.

[0067] When multiple colors are over-enhanced at the edge of the filter assembly 100, the saturation of the first sub-color block portion 11 of the corresponding color is designed to be smaller than the saturation of the second sub-color block portion 21 of the corresponding color. The multiple colors may be two, three, four, etc., or even all colors.

[0068] For example, when the edge blue and red of the filter assembly 100 are enhanced at the same time, the saturation of the blue first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the blue second sub-color resist portion 21 in the second color resist portion 2, and the saturation of the red first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the red second sub-color resist portion 21 in the second color resist portion 2;

[0069] When the edge blue and green of the filter assembly 100 are enhanced at the same time, the saturation of the blue first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the blue second sub-color resist portion 21, and the saturation of the green first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the green second sub-color resist portion 21 in the second color resist portion 2;

[0070] When the edge red and green of the filter assembly 100 are enhanced at the same time, the saturation of the red first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the red second sub-color resist portion 21 in the second color resist portion 2, and the saturation of the green first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the green second sub-color resist portion 21 in the second color resist portion 2;

[0071] When the edge blue, green and red colors of the filter assembly 100 are enhanced, the saturation of the blue first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the blue second sub-color resist portion 21 in the second color resist portion 2, and the saturation of the green first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the green second sub-color resist portion 21 in the second color resist portion 2, and the saturation of the red first sub-color resist portion 11 in the first color resist portion 1 is less than the saturation of the red second sub-color resist portion 21 in the second color resist portion 2, and so on.

[0072] Based on the edge-enhanced color in the filter assembly 100, the saturation of the first sub-color resistance portion 11 of the corresponding color and the saturation of the second sub-color resistance portion 21 of the corresponding color are adjusted in a targeted manner, thereby achieving fine-grained control of the oversaturation of the edge color of the filter assembly 100, accurately suppressing and correcting the edge-enhanced color, and making the overall color of the light after passing through the filter assembly 100 more uniform.

[0073] Example 3

[0074] Embodiment 3 of the present application provides a filter assembly 100. The difference between the filter assembly 100 of embodiment 3 and embodiment 1 is that:

[0075] The first color resist portion 1 and the second color resist portion 2 are made of the same material, and the thickness of the first color resist portion 1 is smaller than the thickness of the second color resist portion 2 .

[0076] The first color resist portion 1 and the second color resist portion 2 can use the same material, such as a resin material containing a dye, or a photoresist with added pigment particles, etc., which can reduce the complexity of the production and procurement process, and the first color resist portion 1 and the second color resist portion 2 made of the same material can more easily achieve good optical and physical compatibility, such as consistent thermal expansion coefficients, thereby improving the overall stability and durability of the filter assembly 100.

[0077] During design, the thickness of the first color resist portion 1 and the second color resist portion 2 can be flexibly adjusted to change the difference in saturation between the two according to different actual production conditions and production requirements. For example, the thickness of the second color resist portion 2 can be kept unchanged and the thickness of the first color resist portion 1 can be reduced; or, the thickness of the first color resist portion 1 can be kept unchanged and the thickness of the second color resist portion 2 can be increased; or, while the thickness of the first color resist portion 1 is reduced, the thickness of the second color resist portion 2 can be increased.

[0078] The first color resist portion 1 and the second color resist portion 2 have the same thickness, and the color point density of the first color resist portion 1 is smaller than the color point density of the second color resist portion 2 .

[0079] The first color resist portion 1 and the second color resist portion 2 have the same thickness, and uniform standards and parameters can be maintained in process steps such as cutting and coating, thereby reducing the difficulty of processing.

[0080] During design, the color point density of the materials of the first color resist portion 1 and the second color resist portion 2 can be flexibly adjusted to achieve a difference in saturation between the two according to different actual production conditions and production requirements. For example, the material of the second color resist portion 2 can be kept unchanged, that is, the color point density of the second color resist portion 2 can be kept unchanged, and a new material with a lower color point density can be selected or mixed as the material of the first color resist portion 1; or, the material of the first color resist portion 1 can be kept unchanged, that is, the color point density of the first color resist portion 1 can be kept unchanged, and a new material with a higher color point density can be selected or mixed as the material of the second color resist portion 2; or, a new material with a lower color point density can be selected or mixed as the material of the first color resist portion 1, and a new material with a higher color point density can be selected or mixed as the material of the second color resist portion 2. Or,

[0081] The thickness of the first color resist portion 1 is smaller than that of the second color resist portion 2 , and the color point density of the first color resist portion 1 is smaller than that of the second color resist portion 2 .

[0082] By adjusting the thickness and material parameters at the same time, the filter assembly 100 can achieve more precise saturation adjustment, making the final color more consistent. In addition, by properly matching materials and thickness, it helps to reduce the risk of deformation caused by factors such as temperature changes and mechanical stress, thereby increasing the service life of the product.

[0083] The difference in saturation of the first color resist portion 1 being smaller than that of the second color resist portion 2 based on thickness and / or material properties not only achieves refined color management, but also takes into account the convenience of the production process and the stability and durability of the product, and can be more easily controlled and adjusted in the actual production process.

[0084] Example 4

[0085] Embodiment 4 of the present application provides a filter assembly 100. The difference between the filter assembly 100 of embodiment 4 and embodiment 1 is that it further includes a filter layer (not shown in the figure);

[0086] The filter layer is arranged on the first color block part 1, and the filter layer can absorb or scatter part of the light within the target wavelength range; by adding the filter layer to the first color block part 1, the light within the specific target wavelength range can be absorbed or scattered, and the saturation of the first color block part 1 can be reduced, so as to more finely control the color saturation of the edge area, so that the overall color of the light after passing through the filter assembly 100 is more uniform. Or,

[0087] The filter layer is arranged on the second color block part 2, and is used to pass light within the target wavelength range; the filter layer can selectively pass light within a specific target wavelength range, achieve more precise control of the final transmitted color, improve the saturation of the second color block part 2, and make the overall color of the light after passing through the filter assembly 100 more uniform. Or,

[0088] The filter layer is arranged on the first color-blocking portion 1, and the filter layer can absorb or scatter part of the light within the target wavelength range; the filter layer is arranged on the second color-blocking portion 2, and the filter layer is used to pass the light within the target wavelength range;

[0089] The target wavelength is a wavelength of light having a color corresponding to a saturation of the first color resist portion 1 being less than a saturation of the second color resist portion 2 .

[0090] It can be understood that when the light emitted by the light source in the display panel passes through the first color resist portion 1 and the second color resist portion 2, the light that exhibits reduced saturation in the first color resist portion 1 relative to the second color resist portion 2 can be the first light, and the wavelength range of the first light is the target wavelength range.

[0091] For example, when the blue saturation in the first color resist portion 1 is less than the blue saturation in the second color resist portion 2, the first light is blue light, and the target wavelength range is the wavelength range of blue light, that is, 450-495nm. At this time, the filter layer can be set in the first color resist portion 1, and when the filter layer is set in the first color resist portion 1, it is designed to absorb or scatter part of the light in the wavelength range of 450-495nm; the filter layer can also be set in the second color resist portion 2, and when the filter layer is set in the second color resist portion 2, it is designed to selectively transmit the light in the wavelength range of 450-495nm, and so on.

[0092] By arranging filter layers with different functional characteristics in the first color resistance part 1 and the second color resistance part 2, fine control of light is achieved, which not only solves the problem of color imbalance in the edge area, but also ensures the color expression of the middle area, and ultimately improves the overall image quality and viewing experience.

[0093] Example 5

[0094] like Figure 1 As shown, Embodiment 5 of the present application provides a filter assembly 100. The difference between the filter assembly 100 of Embodiment 5 and Embodiment 1 is that:

[0095] The first color resist portion 1 is ring-shaped, and the second color resist portion 2 is disposed inside the first color resist portion 1 .

[0096] Since the first color blocking portion 1 can be located at the edge of the filter assembly 100, its lower saturation design can effectively suppress the color oversaturation problem that may occur at the edge. This annular structure ensures full coverage of the filter edge, making the overall color of the light passing through the filter assembly 100 more uniform.

[0097] Example 6

[0098] like Figure 5 and Figure 6 As shown, Embodiment 6 of the present application provides a filter assembly 100. The difference between the filter assembly 100 of Embodiment 6 and Embodiment 1 is that:

[0099] The second color resist portion 2 includes an adjacent first sub-segment 22 and a second sub-segment 23, the first sub-segment 22 is adjacent to the first color resist portion 1, the first sub-segment 22 is arranged between the first color resist portion 1 and the second sub-segment 23, the saturation of the first color resist portion 1 is less than the saturation of the first sub-segment 22, and the saturation of the first sub-segment 22 is less than the saturation of the second sub-segment 23.

[0100] For example, Figure 5 As shown, the first color resist portion 1 may be annular, the first sub-segment 22 may be annular, and the second sub-segment 21 is arranged inside the first sub-segment 22; or Figure 6 As shown, the first color resist portion 1 may be strip-shaped, the first sub-segment 22 may be strip-shaped, and the second sub-segment 21 is arranged on a side of the first sub-segment 22 away from the first color resist portion 1. It should be understood that the shapes of the first color resist portion 1 and the first sub-segment 22 are only for illustration, and the shapes in actual design are not limited thereto.

[0101] By dividing the second color resist portion 2 into different sub-segments, the color presentation of each area can be precisely controlled, and by adjusting the saturation difference between different sub-segments, further refinement and liberalization of color control can be achieved, thereby improving the overall image quality and adaptability, and enhancing the adaptability of the filter assembly 100 to different use conditions and display requirements. The relative position of the first sub-segment 22 and the second sub-segment 23 can refer to the relative position of the second color resist portion 2 and the first color resist portion 1.

[0102] When the filter assembly 100 is applied to stage lighting, a plurality of sub-segments with different saturations may be provided to adjust the color effect of the lighting, and the positional relationship of the plurality of sub-segments may be designed according to the effect requirements.

[0103] Example 7

[0104] like Figure 1 , Figure 2 and Figure 7 As shown, Embodiment 7 of the present application provides a display panel, including:

[0105] substrate 200;

[0106] The filter assembly 100 disposed on the substrate 200 includes:

[0107] A first color resist portion 1 located in the edge region, wherein the first color resist portion 1 corresponds to a first pixel region of the substrate 200;

[0108] A second color resist portion 2, adjacent to the first color resist portion 1, and corresponding to a second pixel region of the substrate 200;

[0109] The color saturation of the light emitted by the display panel after passing through the first color resist portion 1 is less than the color saturation of the light after passing through the second color resist portion 2 .

[0110] The display panel may be an LED display panel or an organic light-emitting diode (OLED) display panel, etc.

[0111] When the display panel is an LED display panel, the filter assembly 100 can be integrated on the substrate 200, and the sub-color resistance portion of each color resistance portion corresponds to the corresponding pixel area on the substrate 200 to achieve color balance and optimize the display effect; when the display panel is an OLED display panel, since each of its sub-pixels is composed of independent organic light-emitting materials of different colors (such as red, green, blue, etc.), these light-emitting materials are directly responsible for generating light of different colors. At this time, the saturation of each sub-pixel is adjusted by controlling the material of each sub-pixel, that is, the sub-pixel plays the role of the filter assembly 100 in Example 1 of the present application, and the sub-pixel can be deposited on the substrate by evaporation or printing process.

[0112] The substrate 200 is used to carry and construct the base material of the functional layer of the display panel, and is usually made of glass, plastic film or flexible material, and the specific material selection depends on the type of display panel. The display panel of Example 7 of the present application introduces a filter assembly 100 with a differentiated saturation design. The saturation of the first color resistance part 1 of the filter assembly 100 is less than the saturation of the second color resistance part 2. This differentiated design neutralizes the excessive enhancement of the edge color of the filter assembly 100 due to expansion space or other process factors, making the overall color of the light after passing through the filter assembly 100 more balanced and consistent, thereby effectively solving the problem of uneven color at the edge of the display panel, making the overall image of the display panel more realistic and natural, significantly improving the image quality and visual experience of the display panel, improving the display quality, and enhancing the market competitiveness of the product.

[0113] The display panel of the present application can be applied to consumer electronic products, such as smart phones, tablet computers, televisions, monitors, virtual reality (VR) head-mounted devices or augmented reality (AR) head-mounted devices, etc.; or professional display devices, such as high-resolution projectors, medical imaging equipment, aviation instrument display panels, etc.

[0114] Example 8

[0115] like Figure 1 , Figure 2 and Figure 7 As shown, Embodiment 8 of the present application provides a display panel. The display panel of Embodiment 8 is different from that of Embodiment 7 in that it includes:

[0116] A backlight source 300 is sequentially arranged on the substrate 200 and the filter assembly 100 along the direction of light emitted by the backlight source 300;

[0117] The light shielding portion 400 is disposed on the backlight source 300 . The light shielding portion 400 can enable the backlight source 300 to form a light emitting area and a shielding area. The filter assembly 100 is directly opposite to the light emitting area.

[0118] The backlight source 300 is one of the core components in the display panel, which may include components such as a back plate 310, a fixing plate 320, a light emitting component 330, a membrane layer 340 and a rubber frame 350. The backlight source 300 can provide uniform and sufficient light to illuminate the entire display area, ensuring the brightness and clarity of the displayed image. Among them, the light emitting component 330 can be set on the back plate 310 through the fixing plate 320. The light emitting component 330 can be a light bar, a plurality of lamp beads or a cold cathode fluorescent lamp tube, etc.; the membrane layer 340 may include a diffusion film 341, a quantum dot film 342, a spectroscopic film 343, a prism film 344, etc., and a specific membrane can be selected according to the actual needs of the backlight source 300; the rubber frame 350 can be set on the back plate 310, and at the same time, it can be spaced apart from the membrane layer 340 and the light emitting component 330 to form an expansion space. For example, Figure 7 As shown, multiple lamp beads emitting blue light can be set on the back plate 310 through the fixing plate 320, and a diffusion film 341, a quantum dot film 342, a three-layer splitter film 343 and a prism film 344 can be sequentially arranged on the light-emitting side of the multiple lamp beads.

[0119] The light shielding part 400 can be pasted with black optical glue or other black light shielding glue with high absorption rate, and it can be precisely attached to the edge or specific area of ​​the backlight source 300 to prevent light from escaping the predetermined light emitting area; or, the light shielding part 400 can also be designed to be integrated with the backlight source 300 component. For example, a component made of opaque plastic, metal or coated with black light absorbing material is embedded in the backlight source frame.

[0120] Since the saturation of the first color resist portion 1 is less than that of the second color resist portion 2, the light that has not been mixed by the diaphragm layer 340 is filtered by the first color resist portion 1 with relatively low saturation, which neutralizes the excessive enhancement of the edge color of the filter assembly 100 caused by the expansion space or other process factors, and avoids the situation where one or more colors of light such as blue light, red light, and green light in the edge area will be highlighted, making the overall color of the light after passing through the filter assembly 100 more balanced and consistent. In addition, since the shading portion 400 more effectively concentrates and limits the light within the luminous area, it can prevent the light from escaping to the part where the image is not displayed (such as the expansion space between the diaphragm and the frame), reduce the background brightness, enhance the dark part of the image, and thus improve the overall contrast. High contrast helps to improve the sharpness and clarity of the image, making the displayed content more vivid and lively.

[0121] Example 9

[0122] Embodiment 9 of the present application provides an electronic device, such as Figure 1 , Figure 2 and Figure 7 As shown, including:

[0123] A display panel, the display panel comprising:

[0124] substrate 200;

[0125] The filter assembly 100 disposed on the substrate 200 includes:

[0126] A first color resist portion 1 located in the edge region, wherein the first color resist portion 1 corresponds to a first pixel region of the substrate 200;

[0127] A second color resist portion 2, adjacent to the first color resist portion 1, and corresponding to a second pixel region of the substrate 200;

[0128] The color saturation of the light emitted by the display panel after passing through the first color resist portion 1 is less than the color saturation of the light after passing through the second color resist portion 2 .

[0129] The electronic device may be a television, a display, a tablet computer, a mobile phone, etc. Since the display panel of the electronic device of the present application is not limited to a narrow frame design, it is widely applicable to electronic devices using Mini LED display panels. The electronic device of Example 9 of the present application, its display panel is configured with a filter assembly 100 with a differentiated saturation design, and the saturation of the first color resistance portion 1 of the filter assembly 100 is less than the saturation of the second color resistance portion 2. This differentiated design neutralizes the excessive enhancement of the edge color of the filter assembly 100 due to expansion space or other process factors, making the overall color of the light after passing through the filter assembly 100 more balanced and consistent, significantly improving the overall image quality of the electronic device, and providing a more realistic and natural visual experience. The dominant position of the electronic device in market competition is greatly enhanced, making it stand out among similar products and meeting the growing demand of users for high-quality display effects.

[0130] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
