Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a light conversion component and a display module. Background Technology

[0002] In MiniLED (Mini Light Emitting Diode) COB (Chip on Board) display modules,

[0003] The blue light emitted by the blue MiniLED chip in the backlight assembly illuminates the color conversion film (any of the phosphor film, light conversion film, and quantum dot diffuser), exciting the quantum dots inside the color conversion film and causing them to emit red and green light. During this process, the red and green light emitted by the quantum dots in the color conversion film mixes with the blue light illuminating the color conversion film, ultimately forming white light.

[0004] In related technologies, the color conversion master plate includes one conversion master plate and two water-oxygen barrier master plates. The conversion master plate is doped with quantum dots, and the two water-oxygen barrier master plates are respectively disposed on opposite sides of the conversion master plate along its thickness direction. One of the water-oxygen barrier master plates has a cutting line on its side facing away from the conversion master plate. The color conversion master plate is cut along this cutting line using a cutting device to obtain multiple independent color conversion films. In these related technologies, the sidewalls of the fabricated color conversion films are exposed to air. External moisture easily permeates through the sidewalls of the color conversion films, diffusing from the sidewalls towards the center of the films, eroding them and forming a failure zone around the center of the films, ultimately reducing the light conversion effect of the color conversion films. Summary of the Invention

[0005] Therefore, it is necessary to address the problem that external moisture can easily penetrate the sidewalls of the color conversion film and erode it, leading to a reduction in the light conversion effect of the color conversion film. In this regard, a light conversion component and display module are proposed.

[0006] A light conversion component, comprising:

[0007] A light conversion film has a central region and a border region, the border region surrounding the outer periphery of the central region, the light conversion film comprising:

[0008] A light conversion structure, wherein a portion of the light conversion structure is located in the central region and another portion is located in the border region;

[0009] The moisture and heat resistance of the light conversion structure in the border area is greater than that of the light conversion structure in the center area.

[0010] In this embodiment, the light conversion component divides the light conversion film into a central region and a border region surrounding the central region. A portion of the light conversion structure is located in the central region, and another portion is located in the border region, allowing the other portion of the light conversion structure to surround the periphery of a portion of the light conversion structure. By setting the humidity and heat resistance of the light conversion structure in the border region to be greater than that in the central region, the humidity and heat resistance of the light conversion structure in the border region is improved. Improving the humidity and heat resistance of the light conversion structure in the border region enhances its resistance to corrosion and high temperatures, reducing the risk of damage due to moisture erosion or inability to withstand high ambient temperatures. This reduces the risk of failure of the light conversion structure in the border region, ensuring its normal operation, improving the light conversion effect, and enhancing the light conversion capability of the light conversion film.

[0011] This application also proposes a display module, including the light conversion component, and

[0012] A backlight assembly for generating light, wherein the backlight assembly and the light conversion assembly are arranged sequentially along the thickness direction of the light conversion film; the side of the backlight assembly closest to the light conversion assembly is configured as the light-emitting side of the backlight assembly.

[0013] In this embodiment, the display module arranges the backlight assembly and the light conversion assembly sequentially along the thickness direction of the light conversion film, with the side of the backlight assembly closer to the light conversion assembly being the light-emitting side. This allows the light emitted from the light-emitting side of the backlight assembly to enter the light conversion film of the light conversion assembly in the direction from the backlight assembly to the light conversion assembly, thereby stimulating the light conversion film of the light conversion assembly to emit light.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] Please see Figure 1 and Figure 11 , Figure 1 A top view of a light conversion component 100 according to an embodiment of this application is shown. An embodiment of this application provides a light conversion component 100, which serves as a color conversion film for a display module 10. Specifically, light emitted from the backlight component 200 of the display module 10 enters the light conversion component 100 and can stimulate the light conversion component 100 to generate colored light. This colored light mixes with the light emitted from the backlight component 200 to form white light.

[0037] The light conversion assembly 100 includes a light conversion film 110, which has a central region A1 and a border region A2, with the border region A2 surrounding the outer periphery of the central region A1. The light conversion film 110 includes a light conversion structure 111, which is a component in the light conversion assembly 100 used to convert light. Specifically, the light emitted by the backlight assembly 200 of the display module 10 mainly enters the light conversion structure 111, exciting the light conversion structure 111 to generate colored light. In other words, the white light generated by the display module 10 is formed by mixing the colored light generated by the light conversion structure 111 with the light emitted by the backlight assembly 200 of the display module 10.

[0038] A portion of the light conversion structure 111 is located in the central region A1, and another portion is located in the border region A2. The damp heat resistance of the light conversion structure 111 in the border region A2 is greater than that in the central region A1. Damp heat resistance can be tested using a damp heat resistance performance test.

[0039] In this embodiment, the light conversion component 100 divides the light conversion film 110 into a central region A1 and a border region A2 surrounding the central region A1. A portion of the light conversion structure 111 of the light conversion film 110 is located in the central region A1, and another portion is located in the border region A2. This allows another portion of the light conversion structure 111 to surround the outer periphery of a portion of the light conversion structure 111. By setting the damp heat resistance of the light conversion structure 111 in the border region A2 to be greater than that in the central region A1, the damp heat resistance of the light conversion structure 111 in the border region A2 is improved. By improving the resistance to damp heat of the light conversion structure 111 in the border area A2, the corrosion resistance and high temperature resistance of the light conversion structure 111 in the border area A2 can be enhanced, reducing the risk of damage to the light conversion structure 111 in the border area A2 due to water vapor corrosion or inability to withstand high ambient temperatures. This reduces the risk of failure of the light conversion structure 111 in the border area A2, ensures the normal operation of the light conversion structure 111 in the border area A2, improves the light conversion effect of the light conversion structure 111, and enhances the light conversion capability of the light conversion film 110.

[0040] Please see Figure 1 and Figure 2 In some implementations, the light conversion structure 111 includes a substrate layer 111-1, red quantum dots (not shown), and green quantum dots (not shown). The substrate layer 111-1 is located at least in the central region A1. Red quantum dots are at least doped within the substrate layer 111-1 in the central region A1, and green quantum dots are at least doped within the substrate layer 111-1 in the central region A1.

[0041] In this embodiment, the light conversion component 100 includes a substrate layer 111-1 in the light conversion structure 111, with the substrate layer 111-1 located in the central region A1. Red quantum dots and green quantum dots are doped in the substrate layer 111-1 in the central region A1, so that when light emitted from the light source enters the substrate layer 111-1 in the central region A1, it can excite the red quantum dots and green quantum dots in the substrate layer 111-1 in the central region A1 to emit red light and green light respectively.

[0042] Please see Figure 1 and Figure 2 In some implementations, the substrate layer 111-1 is also located in the border region A2. Red quantum dot materials and green quantum dot materials are also doped into the substrate layer 111-1 in the border region A2.

[0043] In one example, the red quantum dot material in the border region A2 has a greater resistance to damp heat than the red quantum dot material in the central region A1.

[0044] In one example, the damp heat resistance of the green quantum dots in the border region A2 is greater than that of the green quantum dot material in the central region A1.

[0045] In this embodiment, the light conversion component 100 has a substrate layer 111-1 located in the frame region A2. Red quantum dot material and green quantum dot material are also doped in the substrate layer 111-1 in the frame region A2. This allows the light emitted by the light source to enter the substrate layer 111-1 in the frame region A2 and excite the red quantum dots and green quantum dots in the substrate layer 111-1 in the frame region A2 to emit red light and green light respectively.

[0046] By setting the humidity and heat resistance of the red quantum dot material in the border region A2 to be greater than that in the central region A1, the humidity and heat resistance of the red quantum dot material in the border region A2 is improved. Increasing the humidity and heat resistance of the red quantum dot material in the border region A2 enhances its resistance to moisture erosion, ensuring its proper functioning.

[0047] By setting the humidity and heat resistance of the green quantum dots in the border region A2 to be greater than that in the central region A1, the humidity and heat resistance of the green quantum dot material in the border region A2 is improved. Increasing the humidity and heat resistance of the green quantum dots in the border region A2 enhances the resistance of the green quantum dot material in the border region A2 to moisture erosion, ensuring that the green quantum dot material in the border region A2 can function normally.

[0048] Please see Figure 1 and Figure 2In some implementations, the half-maximum width (WHM) of the red quantum dot material in the central region A1 is narrower than that of the red quantum dot material in the border region A2.

[0049] In one example, the half-maximum width (WHM) of the green quantum dot material in the central region A1 is narrower than that of the green quantum dot material in the border region A2.

[0050] In this embodiment, the light conversion component 100 sets the half-peak width of the red quantum dot material in the central region A1 to be narrower than that of the red quantum dot material in the border region A2. This allows the light generated by the red quantum dot material in the central region A1 to have a higher purity than that generated by the red quantum dot material in the border region A2 when the light generated by the light source excites the red quantum dot materials in both the central region A1 and the border region A2. This improves the light conversion effect of the light conversion structure 111 located in the central region A1.

[0051] Similarly, by setting the half-width at half-maximum (WHM) of the green quantum dot material in the central region A1 to be narrower than that of the green quantum dot material in the border region A2, when the light generated by the light source excites the green quantum dot materials in the central region A1 and the border region A2, the purity of the light produced by the green quantum dot material in the central region A1 is higher than that produced by the green quantum dot material in the border region A2, thereby improving the light conversion effect of the light conversion structure 111 located in the central region A1.

[0052] Please see Figure 1 and Figure 2 In some implementations, the substrate layer 111-1 of the border region A2 is made of a quantum dispersant (not shown).

[0053] In this embodiment, the light conversion component 100, by setting the material of the substrate layer 111-1 of the border region A2 to include a quantum dispersant, and using a quantum dispersant to make the substrate layer 111-1 of the border region A2, can stably disperse the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the border region A2, reduce the aggregation of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the border region A2 due to their high surface energy, maintain the uniform distribution of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the border region A2, and ensure the luminous efficiency and color purity of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the border region A2.

[0054] Please see Figure 1 and Figure 2 In some implementations, the substrate layer 111-1 of the central region A1 is made of a quantum dispersant.

[0055] In this embodiment, the light conversion component 100 includes a quantum dispersant in the substrate layer 111-1 of the central region A1. By using a quantum dispersant to make the substrate layer 111-1 of the central region A1, the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the central region A1 can be stably dispersed, reducing the aggregation of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the central region A1 due to their high surface energy. This maintains the uniform distribution of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the central region A1, and ensures the luminous efficiency and color purity of the red quantum dot material and the green quantum dot material in the substrate layer 111-1 of the central region A1.

[0056] Please see Figure 1 and Figure 2 In some implementations, the substrate layer 111-1 of the border area A2 is made of a water- and oxygen-resistant material.

[0057] In this embodiment, the light conversion component 100, by setting the material of the substrate layer 111-1 of the border region A2 to include a water- and oxygen-resistant material, can improve the water- and oxygen-resistant ability of the substrate layer 111-1 of the border region A2, reduce the risk of external moisture and air eroding the red quantum dot material and green quantum dot material in the substrate layer 111-1 of the border region A2, ensure the normal operation of the red quantum dot material and green quantum dot material in the substrate layer 111-1 of the border region A2, and thus improve the light conversion effect of the light conversion structure 111 of the border region A2.

[0058] Please see Figure 1 and Figure 2 In some implementations, the substrate layer 111-1 of the central region A1 is made of a water- and oxygen-resistant material. Optionally, the water- and oxygen-resistant material includes materials such as ethylene-vinyl alcohol copolymer, polyvinylidene chloride, and polystyrene.

[0059] In this embodiment, the light conversion component 100, by setting the material of the substrate layer 111-1 of the central region A1 to include a water- and oxygen-resistant material, can improve the water- and oxygen-resistant ability of the substrate layer 111-1 of the central region A1, reduce the risk of external water vapor and air erosion of the red quantum dot material and green quantum dot material in the substrate layer 111-1 of the central region A1, ensure the normal operation of the red quantum dot material and green quantum dot material in the substrate layer 111-1 of the central region A1, and thus improve the light conversion effect of the light conversion structure 111 of the central region A1.

[0060] Please see Figure 1 and Figure 2In some implementations, the material of the light conversion structure 111 in the border area A2 includes phosphor.

[0061] In this embodiment, the light conversion component 100 is configured such that the material of the light conversion structure 111 in the border area A2 includes phosphor, so that when light emitted from the light source enters the light conversion structure 111 in the border area A2, the phosphor-made light conversion structure 111 can be excited to generate light.

[0062] Please see Figure 1 In some implementations, the light conversion film 110 includes an isolation structure 112, the material of which includes a water- and oxygen-resistant material. The isolation structure 112 is at least partially located within the central region A1, and the isolation structure 112 within the central region A1 separates the light conversion structure 111 of the central region A1 from the light conversion structure 111 of the border region A2.

[0063] In this embodiment, the light conversion component 100 includes an isolation structure 112 in the light conversion film 110. The isolation structure 112 is at least partially located within the central region A1. By using the isolation structure 112 within the central region A1, the light conversion structure 111 in the central region A1 is separated from the light conversion structure 111 in the border region A2. This allows external moisture or air to enter the light conversion structure 111 in the border region A2, making it difficult for moisture or oxygen to enter the isolation structure 112 in the central region A1. In other words, it blocks moisture or oxygen from entering the isolation structure 111 in the border region A2, thus protecting the isolation structure 112 in the central region A1.

[0064] Please see Figure 1 and Figure 3 In some implementations, a portion of the isolation structure 112 is located within the central region A1, and another portion is located within the border region A2. The isolation structure 112 of the border region A2 divides the light conversion structure 111 of the border region A2 into multiple first light conversion modules 111-2. The structure of the first light conversion module 111-2 includes, but is not limited to, a square or a regular hexagon.

[0065] In one example, in the border area A2, multiple first light conversion modules 111-2 are arranged in multiple rows along the first direction V1; the first direction V1 intersects with the thickness direction V3 of the light conversion film 110.

[0066] In one example, among multiple first ray conversion modules 111-2, the first ray conversion module 111-2 in the first row is located on one side of the ray conversion structure 111 in the central region A1 along the first direction V1.

[0067] In one example, the last row of the first ray conversion module 111-2 is located on the other side of the ray conversion structure 111 in the central region A1 along the first direction V1.

[0068] In this embodiment, the light conversion component 100 has an isolation structure 112, with a portion located in the central region A1 and another portion in the border region A2. This isolation structure 112 divides the light conversion structure 111 in the border region A2 into multiple first light conversion modules 111-2. This ensures that any two adjacent first light conversion modules 111-2 are separated by the isolation structure 112 in the border region A2, preventing the transfer of water vapor or oxygen between adjacent modules. By being positioned in the border region A2, the multiple first light conversion modules 111-2 are arranged in multiple rows along the first direction V1, resulting in a neat and orderly arrangement.

[0069] By setting multiple first light conversion modules 111-2 in rows, with the first row of first light conversion modules 111-2 located on one side of the light conversion structure 111 in the central region A1 along the first direction V1, the water vapor or oxygen on the outer periphery of the light conversion structure 111 is separated from the side of the light conversion structure 111 in the central region A1 along the first direction V1 by the first row of first light conversion modules 111-2. In this way, direct contact between the side of the light conversion structure 111 in the central region A1 along the first direction V1 and the water vapor or oxygen on the outer periphery of the light conversion structure 111 can be prevented, reducing the risk of water vapor or oxygen on the outer periphery of the light conversion structure 111 corroding the light conversion structure 111 in the central region A1 from the side of the light conversion structure 111 in the central region A1 along the first direction V1.

[0070] By setting multiple first light conversion modules 111-2, with the last row of first light conversion modules 111-2 located on the other side of the light conversion structure 111 in the central region A1 along the first direction V1, the water vapor or oxygen on the outer periphery of the light conversion structure 111 is separated from the other side of the light conversion structure 111 in the central region A1 along the first direction V1 by the last row of first light conversion modules 111-2. In this way, direct contact between the other side of the light conversion structure 111 in the central region A1 and the water vapor or oxygen on the outer periphery of the light conversion structure 111 can be prevented, reducing the risk of water vapor or oxygen on the outer periphery of the light conversion structure 111 eroding the light conversion structure 111 in the central region A1 from the other side of the light conversion structure 111 in the central region A1 along the first direction V1.

[0071] Please see Figure 1 and Figure 3In some implementations, among the multiple rows of first light conversion modules 111-2, each row of first light conversion modules 111-2 between the first row and the last row of first light conversion modules 111-2 is located on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, where the second direction V2 intersects with the first direction V1 and the thickness direction V3 of the light conversion film 110.

[0072] In this embodiment, the light conversion component 100 is configured such that each of the first light conversion modules 111-2 between the first row and the last row of the first light conversion modules 111-2 is located on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2. This ensures that the opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2 are separated from the water vapor or oxygen around the light conversion structure 111 by the first row of the first row and the last row of the first light conversion modules 111-2. This prevents the opposite sides of the light conversion structure 111 in the central region A1 from directly contacting the water vapor or oxygen around the light conversion structure 111 along the second direction V2, reducing the risk of water vapor or oxygen around the light conversion structure 111 eroding the light conversion structure 111 in the central region A1 from the opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2.

[0073] Please see Figure 3 and Figure 4 In some implementations, among the multiple rows of first light conversion modules 111-2 located between the first row of first light conversion modules 111-2 and the last row of first light conversion modules 111-2, at least a portion of the rows of first light conversion modules 111-2 are located between the first row of first light conversion modules 111-2 and the light conversion structure 111 of the central region A1.

[0074] In this embodiment, the light conversion component 100 increases the number of first light conversion modules 111-2 rows located at the top row between the first light conversion modules 111-2 rows and the light conversion structure 111 in the central region A1. This increases the number of first light conversion modules 111-2 rows on one side of the light conversion structure 111 in the central region A1 along the first direction V1. Thus, when water vapor or oxygen from the periphery of the light conversion structure 111 erodes the light conversion structure 111 in the central region A1 along the first direction V1, the multiple rows of first light conversion modules 111-2 rows on one side of the light conversion structure 111 in the central region A1 along the first direction V1 can provide multiple layers of blocking for the water vapor or oxygen, reducing the risk of water vapor or oxygen from the periphery of the light conversion structure 111 entering the light conversion structure 111 in the central region A1 from the one side of the light conversion structure 111 in the central region A1 along the first direction V1.

[0075] Please see Figure 3 and Figure 4 In some implementations, among the multiple rows of first light conversion modules 111-2 located between the first row of first light conversion modules 111-2 and the last row of first light conversion modules 111-2, a portion of the rows of first light conversion modules 111-2 are located between the first row of first light conversion modules 111-2 and the light conversion structure 111 of the central region A1.

[0076] Please see Figure 3 and Figure 4 In one example, among the multiple rows of first ray conversion modules 111-2 located between the first row of first ray conversion modules 111-2 and the last row of first ray conversion modules 111-2, at least a portion of the remaining number of rows of first ray conversion modules 111-2 are located between the last row of first ray conversion modules 111-2 and the ray conversion structure 111 of the central region A1.

[0077] In this embodiment, the light conversion component 100 increases the number of first light conversion modules 111-2 rows located on the other side of the light conversion structure 111 in the central region A1 along the first direction V1 by arranging at least a portion of the remaining number of first light conversion modules 111-2 rows between the un-rowed first light conversion modules 111-2 rows and the light conversion structure 111 in the central region A1. Thus, when water vapor or oxygen around the light conversion structure 111 erodes the light conversion structure 111 in the central region A1 along the first direction V1, the multiple rows of first light conversion modules 111-2 rows located on the other side of the light conversion structure 111 in the central region A1 along the first direction V1 can provide multiple layers of blocking for water vapor or oxygen, reducing the risk of water vapor or oxygen around the light conversion structure 111 entering the light conversion structure 111 in the central region A1 from the other side of the first direction V1.

[0078] Please see Figure 4 and Figure 5 In some implementations, a portion of the remaining first light conversion modules 111-2 rows are located between the un-rowed first light conversion modules 111-2 rows and the light conversion structure 111 of the central region A1.

[0079] Please see Figure 4 and Figure 5 In one example, in the remaining number of first light conversion modules 111-2 rows, another part of the first light conversion modules 111-2 rows are located on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, and the second direction V2 intersects with the first direction V1 and the thickness direction V3 of the light conversion film 110.

[0080] In this embodiment, the light conversion component 100, by setting another portion of the remaining number of first light conversion modules 111-2 rows to be located on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, can separate the opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2 from the water vapor or oxygen located on the periphery of the light conversion structure 111. In this way, the other portion of the remaining number of first light conversion modules 111-2 rows can block the water vapor or oxygen on the periphery of the light conversion structure 111, reducing the risk of water vapor or oxygen on the periphery of the light conversion structure 111 entering the light conversion structure 111 in the central region A1 from the opposite sides of the light conversion structure 111 in the second direction V2.

[0081] Please see Figure 5 In some implementations, in each row of first light conversion modules 111-2 on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, a portion of the first light conversion modules 111-2 are located on one side of the light conversion structure 111 in the central region A1 along the second direction V2, and the number of such portions of first light conversion modules 111-2 is a first value.

[0082] Please see Figure 5 In one example, in each row of first light conversion modules 111-2 on opposite sides of the light conversion structure 111 in the central region A1 along the second direction, another portion of the first light conversion modules 111-2 is located on the other side of the light conversion structure 111 in the central region A1 along the second direction V2, and the number of this portion of first light conversion modules 111-2 is a second value; the second value is greater than or equal to the first value.

[0083] In this embodiment, the light conversion component 100 is configured such that, in each row of first light conversion modules 111-2 located on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, a portion of the first light conversion modules 111-2 are located on one side of the light conversion structure 111 in the central region A1 along the second direction V2, so that this portion of the first light conversion modules 111-2 can separate the side of the light conversion structure 111 in the central region A1 along the second direction V2 from the water vapor or oxygen around the light conversion structure 111.

[0084] By setting up each row of first light conversion modules 111-2 on opposite sides of the light conversion structure 111 in the central region A1 along the second direction V2, and another portion of the first light conversion modules 111-2 located on the other side of the light conversion structure 111 in the central region A1 along the second direction V2, this portion of the first light conversion modules 111-2 can separate the other side of the light conversion structure 111 in the central region A1 along the second direction V2 from the water vapor or oxygen around the light conversion structure 111.

[0085] Please see Figure 5 In some implementations, the number of first light conversion modules 111-2 in any two adjacent rows of first light conversion modules 111-2 along the second direction V2 of the light conversion structure 111 located in the central region A1 is greater than or equal to the number of first light conversion modules 111-2 in the other row of first light conversion modules 111-2.

[0086] Please see Figure 5 and Figure 6In some implementations, the isolation structure 112 of the central region A1 divides the light conversion structure 111 of the central region A1 into multiple second light conversion modules 111-3; the multiple second light conversion modules 111-3 are arranged in multiple rows along the first direction V1. The structure of the second light conversion module 111-3 includes, but is not limited to, a square or a regular hexagon.

[0087] Please see Figure 5 and Figure 6 In one example, multiple rows of second light conversion modules 111-3 correspond one-to-one with multiple rows of first light conversion modules 111-2 on opposite sides of the light conversion structure 111 located in the central region A1 along the second direction V2; the first light conversion modules 111-2 corresponding to each row of second light conversion modules 111-3 are located on opposite sides of the row of second light conversion modules 111-3 along the second direction V2.

[0088] In this embodiment, the light conversion component 100 divides the light conversion structure 111 of the central region A1 into multiple second light conversion modules 111-3 by setting an isolation structure 112 in the central region A1. This ensures that any two adjacent second light conversion modules 111-3 are separated by the isolation structure 112 in the central region A1, preventing the transfer of water vapor or oxygen between adjacent second light conversion modules 111-3. By arranging multiple second light conversion modules 111-3 in multiple rows along the first direction V1, the multiple second light conversion modules 111-3 can be arranged neatly, making the light conversion structure 111 of the central region A1 more compact and smaller in size. By setting a first light conversion module 111-2 corresponding to each second light conversion module 111-3 row, located on opposite sides of the second light conversion module 111-3 row along the second direction V2, such that each second light conversion module 111-3 row has a corresponding first light conversion module 111-2 of the first light conversion module 111-2 row on opposite sides of the second direction V2, the first light conversion module 111-2 row corresponding to the second light conversion module 111-3 row can protect the opposite sides of the second light conversion module 111-3 row along the second direction V2.

[0089] Please see Figure 5 and Figure 6 In some implementations, the dimension D1 of the second light conversion module 111-3 along the second direction V2 is equal to the dimension D8 of the first light conversion module 111-2 along the second direction V2 in the first row of the first light conversion module 111-2.

[0090] Please see Figure 5 and Figure 6In some implementations, the first light conversion module 111-2 at the beginning of each row of first light conversion modules 111-2 is aligned with the side of the first light conversion module 111-2 at the beginning of the adjacent row of first light conversion modules 111-2 that is aligned with the side of the first light conversion module 111-2 at the beginning of the adjacent row of first light conversion modules 111-2 that is aligned with the side of the first light conversion module 111-2 that is aligned with the first direction V2 that is aligned with the first direction V1.

[0091] Please see Figure 5 and Figure 6 In one example, the first light conversion module 111-2 at the end of each row of first light conversion modules 111-2, on the side away from the central region A1 along the second direction V2, is aligned with the first light conversion module 111-2 at the end of the adjacent row of first light conversion modules 111-2, on the side away from the central region A1 along the second direction V2.

[0092] In this embodiment, the light conversion component 100 is configured such that the first light conversion modules 111-2 at the beginning of any two adjacent rows of first light conversion modules 111-2 are aligned with the side of the first light conversion module 111-2 away from the central region A1 along the second direction V2, so that the first light conversion modules 111-2 at the beginning of any two adjacent rows of first light conversion modules 111-2 have the same degree of contact with water vapor or oxygen on the outer periphery of the light conversion structure 111 of the border region A2.

[0093] By setting the first light conversion module 111-2 at the tail end of any two adjacent rows of first light conversion modules 111-2 to be aligned with the side away from the central region A1 along the second direction V2, the first light conversion module 111-2 at the tail end of any two adjacent rows of first light conversion modules 111-2 has the same degree of contact with water vapor or oxygen on the outer periphery of the light conversion structure 111 of the border region A2.

[0094] Please see Figure 5 and Figure 6 In some implementations, the first light conversion module 111-2 at the beginning of the first light conversion module 111-2 row is parallel to the first direction V1 on the side away from the central region A1 along the second direction V2.

[0095] Please see Figure 5 and Figure 6 In one example, the first ray conversion module 111-2 at the end of the first ray conversion module 111-2 row is parallel to the first direction V1 on the side away from the central region A1 along the second direction V2.

[0096] In this embodiment, the light conversion component 100 has the following characteristics: the first light conversion module 111-2 at the beginning of the first light conversion module 111-2 row is parallel to the first direction V1 on the side away from the central region A1 along the second direction V2; and the first light conversion modules 111-2 at the beginning of any two adjacent rows are aligned on the side away from the central region A1 along the second direction V2. Thus, it can be seen that the first light conversion modules 111-2 at the beginning of multiple rows of first light conversion modules 111-2 are located in the same plane on the side away from the central region A1 along the second direction V2, and this plane is parallel to the first direction V1.

[0097] Since the first light conversion module 111-2 at the end of the first light conversion module 111-2 row is parallel to the first direction V1 on the side away from the central region A1 along the second direction V2, and the first light conversion module 111-2 at the end of any two adjacent rows of first light conversion modules 111-2 is also aligned on the side away from the central region A1 along the second direction V2, it can be known that the first light conversion modules 111-2 at the end of multiple rows of first light conversion modules 111-2 are located in the same plane on the side away from the central region A1 along the second direction V2, and this plane is parallel to the first direction V1.

[0098] Please see Figure 5 and Figure 6 In some implementations, among the multiple rows of first light conversion modules 111-2 between the first row of the first light conversion module 111-2 and the last row of the first light conversion module 111-2, the dimension D3 of the first light conversion module 111-2 at the beginning of the odd-numbered rows along the second direction V2 is equal to the dimension D4 of the first light conversion module 111-2 at the end of the second direction V2.

[0099] Please see Figure 5 and Figure 6 In one example, among the multiple rows of first ray conversion modules 111-2 between the first row and the last row, the first ray conversion module 111-2 at the beginning of the odd-numbered rows has a first value for its dimension D3 along the second direction V2. Optionally, the first value is between 0.1mm and 0.3mm.

[0100] Please see Figure 5 and Figure 6In one example, among the multiple rows of first ray conversion modules 111-2 between the first row and the last row, the dimension D2 of each first ray conversion module 111-2 in the even-numbered rows along the second direction V2 is a second value; the second value is greater than or equal to the first value. Optionally, the second value is between 0.4mm and 0.6mm.

[0101] In this embodiment, the light conversion component 100, by setting the size of the first light conversion modules 111-2 at the beginning and end of the odd-numbered rows of the multiple first light conversion modules 111-2 between the first row and the last row of the first light conversion modules 111-2 along the second direction V2 to be smaller than the size of the first light conversion modules 111-2 along the second direction V2 in the even-numbered rows of the first light conversion modules 111-2, can make the first light conversion modules 111-2 in the odd-numbered rows of the multiple first light conversion modules 111-2 between the first row and the last row of the first light conversion modules 111-2 staggered with the first light conversion modules 111-2 in the even-numbered rows along the first direction V2.

[0102] Please see Figure 5 and Figure 6 In some implementations, in the odd-numbered rows of the first ray conversion modules 111-2, each of the first ray conversion modules 111-2 located between the first ray conversion module 111-2 at the beginning and the first ray conversion module 111-2 at the end has a third value for the dimension D5 along the second direction V2, and the third value is equal to the second value.

[0103] Please see Figure 6 and Figure 7 In some implementations, the surface of the light conversion module (first light conversion module 111-2, second light conversion module 111-3) is covered with a water and oxygen barrier layer 113.

[0104] In this embodiment, the light conversion module 100 does not have separate water and oxygen barrier layers on its opposite sides along its thickness direction. The light conversion module relies solely on its own surface water and oxygen barrier layer 113 to isolate external water vapor or oxygen. In this way, the light conversion module can be changed from a three-layer structure to a single-layer structure, thereby reducing the thickness of the light conversion module and ultimately making the light conversion module 100 thinner.

[0105] Please see Figure 6 and Figure 8In some implementations, the water and oxygen barrier layer 113 of the light conversion module has a substrate layer 113-1 on each of its opposite sides along the thickness direction of the light conversion module. The substrate layer 113-1 is made of PC (Polycarbonate, thermoplastic engineering plastic).

[0106] Please see Figure 6 and Figure 8 In one example, the substrate layer 111-1 is made of PS (Poly styrene).

[0107] In this embodiment, the light conversion component 100 has substrate layers 113-1 on opposite sides of the water-oxygen barrier layer 113 along the thickness direction of the light conversion module. These two substrate layers 113-1 isolate the water-oxygen barrier layer 113 from the external environment along the thickness direction of the light conversion module. This prevents water vapor or oxygen from directly contacting the water-oxygen barrier layer 113. Furthermore, when the ambient temperature outside the light conversion module is high, the substrate layers 113-1 can absorb some of the heat, reducing the amount of heat absorbed by the light conversion module and lowering the risk of damage due to excessive heat absorption. Thus, the light conversion component 100 can operate at higher ambient temperatures, such as above 80 degrees Celsius.

[0108] Please see Figure 6 and Figure 8 In some implementations, the melting point of the substrate layer 113-1 is greater than or equal to 85 degrees Celsius.

[0109] In this embodiment, the light conversion component 100 sets the melting point of the substrate layer 113-1 to be greater than or equal to 85 degrees Celsius, so that the substrate layer 113-1 can be used normally at 85 degrees Celsius. In this way, the maximum operating temperature of the light conversion module can be increased to above 85 degrees Celsius.

[0110] Please see Figure 1 and Figure 9 In some implementations, along the thickness direction V3 of the light conversion film 110, the size D6 of the light conversion structure 111 in the border region A2 is larger than the size D7 of the light conversion structure 111 in the central region A1.

[0111] In this embodiment, the light conversion component 100 has a larger dimension D5 of the light conversion structure 111 in the border region A2 than the dimension D6 of the light conversion structure 111 in the central region A1 by setting the thickness direction V3 of the light conversion film 110. This makes the light conversion structure 111 in the border region A2 thicker. As a result, when light emitted from the light source enters the light conversion structure 111 in the border region A2, the light conversion structure 111 in the border region A2 can emit light with higher purity. By increasing the purity of the light emitted by the light conversion structure 111 in the border area A2, the influence of external moisture, oxygen, or high temperature on the function of the light conversion structure 111 in the border area A2 can be offset, reducing the difference in purity between the light emitted by the light conversion structure 111 in the central area A1 and the light emitted by the light conversion structure 111 in the border area A2; ensuring that the purity of the light emitted by the light conversion structure 111 in the border area A2, affected by external moisture, oxygen, or high temperature, is basically equal to the purity of the light emitted by the light conversion structure 111 in the central area A1, improving the uniformity of the light emission effect of the light conversion structure 111, and improving the light emission effect of the light conversion component 100.

[0112] Please see Figure 1 and Figure 9 In some implementations, along the thickness direction V3 of the light conversion film 110, one side of the light conversion structure 111 in the border region A2 is flush with one side of the light conversion structure 111 in the center region A1.

[0113] Please see Figure 1 and Figure 10 In some implementations, the light conversion assembly 100 includes a light conversion boss 120, which is located on one side of the light conversion structure 111 in the frame region A2 along the thickness direction V3 of the light conversion film 110.

[0114] Optionally, the light conversion boss 120 and the light conversion structure 111 of the border area A2 are an integral structure.

[0115] Optionally, the light conversion boss 120 is attached to one side of the light conversion structure 111 located in the border area A2.

[0116] Please see Figure 1 and Figure 10 In one example, the light conversion boss 120 is ring-shaped and surrounds the light conversion structure 111 in the central region A1.

[0117] In this embodiment, the light conversion component 100 has an annular light conversion protrusion 120 surrounding the light conversion structure 111 in the central region A1 on one side of the light conversion structure 111 in the border region A2. This allows the light emitted from the light conversion protrusion 120 to reinforce the light emitted from the light conversion structure 111 in the border region A2 after the light source enters the light conversion structure 111 and the light conversion protrusion 120 in the border region A2. This counteracts the influence of external moisture, oxygen, or high temperature on the function of the light conversion structure 111 in the border region A2, ensuring that the purity of the light in the border region A2 of the light conversion film 110 is basically equal to the purity of the light in the central region A1 of the light conversion film 110, thereby improving the light emission uniformity of the light conversion film 110.

[0118] Please see Figure 1 and Figure 10 In some implementations, the light conversion protrusion 120 is doped with red and green quantum dots.

[0119] Please see Figure 1 and Figure 10 In one example, the damp heat resistance of the red quantum dots doped within the light conversion protrusion 120 is greater than that of the red quantum dot material in the central region A1.

[0120] Please see Figure 1 and Figure 10 In one example, the damp heat resistance of the green quantum dot material doped within the light conversion protrusion 120 is greater than that of the green quantum dot material in the central region A1.

[0121] In this embodiment, the light conversion component 100, by doping red quantum dots and green quantum dots into the light conversion protrusion 120, enables the red and green quantum dots in the light conversion protrusion 120 to emit red and green light respectively after the light emitted by the light source enters the light conversion protrusion 120.

[0122] By setting the humidity and heat resistance of the red quantum dots doped within the light conversion protrusion 120 to be greater than that of the red quantum dot material in the central region A1, the humidity and heat resistance of the red quantum dots doped within the light conversion protrusion 120 is improved. Improving the humidity and heat resistance of the red quantum dots doped within the light conversion protrusion 120 enhances their resistance to water and oxygen erosion and their high-temperature resistance, ensuring the normal operation of the red quantum dots within the light conversion protrusion 120.

[0123] By setting the humidity and heat resistance of the green quantum dot material doped within the light conversion protrusion 120 to be greater than that of the green quantum dot material in the central region A1, the humidity and heat resistance of the green quantum dots doped within the light conversion protrusion 120 is improved. Improving the humidity and heat resistance of the green quantum dots doped within the light conversion protrusion 120 enhances their resistance to water and oxygen erosion and their high-temperature resistance, ensuring the normal operation of the green quantum dots within the light conversion protrusion 120.

[0124] Please see Figure 1 and Figure 10 In some implementations, the inner wall, outer wall and the side away from the light conversion membrane 110 of the light conversion boss 120 are provided with a water and oxygen barrier layer 113.

[0125] In this embodiment, the light conversion component 100 has a water and oxygen barrier layer 113 on the inner wall of the light conversion protrusion 120. This water and oxygen barrier layer 113 can isolate the inner wall of the light conversion protrusion 120 from external water vapor and oxygen, reducing the risk of external water vapor or oxygen entering the light conversion protrusion 120 from the inner wall and causing corrosion to the light conversion protrusion 120.

[0126] By providing a water and oxygen barrier layer 113 on the outer wall of the light conversion protrusion 120, the water and oxygen barrier layer 113 can isolate the outer wall of the light conversion protrusion 120 from the water vapor and oxygen in the outside, reducing the risk of water vapor or oxygen entering the light conversion protrusion 120 from the outer wall of the light conversion protrusion 120 and causing corrosion to the light conversion protrusion 120.

[0127] By providing a water and oxygen barrier layer 113 on the side of the light conversion protrusion 120 away from the light conversion film 110, the water and oxygen barrier layer 113 can isolate the side of the light conversion protrusion 120 away from the light conversion film 110 from external water vapor and oxygen, reducing the risk of external water vapor or oxygen entering the light conversion protrusion 120 from the side of the light conversion protrusion 120 away from the light conversion film 110 and causing corrosion to the light conversion protrusion 120.

[0128] Please see Figure 1 and Figure 10 In some implementations, the material of the light conversion boss 120 includes phosphor.

[0129] In this embodiment, the light conversion component 100 is configured such that the material of the light conversion protrusion 120 includes phosphor. By using phosphor to make the light conversion protrusion 120, the light emitted by the light source can be excited to generate light when it enters the light conversion protrusion 120.

[0130] Please see Figure 1and Figure 10 In some implementations, along the thickness direction V3 of the light conversion film 110, the light conversion bosses 120 are arranged at intervals with the light conversion film 110.

[0131] Please see Figure 1 and Figure 10 In one example, the orthographic projection of the light conversion boss 120 on the light conversion film 110 is located on the side of the light conversion structure 111 in the border region A2 near the light conversion boss 120, and surrounds the outer periphery of the side of the light conversion structure 111 in the central region A1 near the light conversion boss 120.

[0132] In this embodiment, the light conversion component 100 arranges the light conversion protrusion 120 and the light conversion film 110 at intervals along the thickness direction V3 of the light conversion film 110, so that the light conversion protrusion 120 and the light conversion film 110 can be two separately set parts. In this way, the light conversion protrusion 120 and the light conversion film 110 can be manufactured separately.

[0133] By setting the orthographic projection of the light conversion protrusion 120 on the light conversion film 110, the light conversion structure 111 located in the border area A2 is close to the side of the light conversion protrusion 120, so that the light emitted by the light conversion protrusion 120 can reinforce the light emitted by the light conversion structure 111 in the border area A2.

[0134] By setting the orthographic projection of the light conversion protrusion 120 on the light conversion film 110, the light conversion structure 111 surrounding the central region A1 on the outer periphery of the side near the light conversion protrusion 120, so that the light emitted by the light conversion protrusion 120 along the circumference of the light conversion structure 111 in the border region A2 can reinforce the light emitted from each position of the light conversion structure 111 in the border region A2.

[0135] Please see Figure 1 and Figure 10 In some implementations, the orthographic projection of the light conversion boss 120 onto the light conversion film 110 coincides with the side of the light conversion structure 111 of the frame region A2 that is close to the light conversion boss 120.

[0136] In this embodiment, the light conversion component 100 is configured such that the orthographic projection of the light conversion protrusion 120 on the light conversion film 110 coincides with the side of the light conversion structure 111 of the frame area A2 that is close to the light conversion protrusion 120. This allows the light emitted by the light conversion protrusion 120 to reinforce the light emitted by each area of ​​the light conversion structure 111 of the frame area A2.

[0137] This application also proposes a display module 10, please refer to... Figure 11 , Figure 11 A schematic diagram of the structure of a display module 10 according to an embodiment of this application is shown. The display module 10 includes a light conversion component 100 and a backlight component 200. The backlight component 200 is used to generate light. Along the thickness direction V3 of the light conversion film 110, the backlight component 200 and the light conversion component 100 are arranged sequentially. The side of the backlight component 200 closest to the light conversion component 100 is configured as the light-emitting side of the backlight component 200.

[0138] In this embodiment, the display module 10 arranges the backlight assembly 200 and the light conversion assembly 100 sequentially along the thickness direction V3 of the light conversion film 110, so that the side of the backlight assembly 200 closest to the light conversion assembly 100 is the light-emitting side. This allows the light emitted from the light-emitting side of the backlight assembly 200 to enter the light conversion film 110 of the light conversion assembly 100 in the direction from the backlight assembly 200 to the light conversion assembly 100, thereby stimulating the light conversion film 110 of the light conversion assembly 100 to emit light.

[0139] Please see Figure 11 In some implementations, the outline of the light conversion film 110 is projected onto the backlight assembly 200 in a positive projection, which coincides with the outline of the backlight assembly 200.

[0140] In this embodiment, the display module 10, by setting the outer contour of the light conversion film 110 to coincide with the outer contour of the backlight assembly 200, can enable most of the light emitted from the light-emitting side of the backlight assembly 200 to enter the light conversion film 110 of the light-emitting conversion assembly 100, thereby improving the utilization efficiency of the light emitted by the backlight assembly 200.

[0141] Please see Figure 11 In some implementations, there is a gap between the backlight assembly 200 and the light conversion assembly 100.

[0142] Please see Figure 11 In some implementations, the backlight assembly 200 includes a substrate 210, a light-emitting component 220, and a sealant layer 230. The substrate 210 and the light-emitting component 100 are arranged sequentially along the thickness direction of the light conversion assembly 100. The light-emitting component 220 is located between the substrate 210 and the light conversion assembly 100, and is disposed on the side of the substrate 210 closer to the light conversion assembly 100.

[0143] Please see Figure 11 In one example, the light-emitting component 220 includes a plurality of light-emitting units 221, the orthographic projection of the light-emitting units 221 onto the light conversion film 110, and the light conversion film 110 located in the central region A1 on the side close to the substrate 210.

[0144] Please see Figure 11In one example, the sealant layer 230 is applied to the side of the light-emitting unit 221 away from the substrate 210, and to the side of the substrate 210 close to the light-emitting unit 221.

[0145] Please see Figure 11 In one example, a portion of the orthographic projection of the sealant layer 230 onto the light conversion film 110 coincides with the side of the light conversion structure 111 in the central region A1 that is close to the substrate 210, and another portion of the orthographic projection coincides with the side of the light conversion structure 111 in the border region A2 that is close to the substrate 210.

[0146] In this embodiment, the display module 10 sets the orthogonal projection of the light-emitting unit 221 onto the light conversion film 110, with the light conversion film 110 in the central region A1 located on the side close to the substrate 210. This allows most of the light emitted by the light-emitting unit 221 to enter the light conversion film 110 in the central region A1, thereby exciting the light conversion film 110 in the central region A1 to emit light.

[0147] By covering the side of the light-emitting unit 221 away from the substrate 210 with the sealant layer 230, the sealant layer 230 can isolate external moisture or oxygen from the side of the light-emitting unit 221 away from the substrate 210. By covering the side of the substrate 210 close to the light-emitting unit 221 with the sealant layer 230, the sealant layer 230 can isolate external moisture or oxygen from the side of the substrate 210 close to the light-emitting unit 221.

[0148] Please see Figure 11 In some implementations, the light conversion structure 111 of the frame region A2 has a corresponding sealant layer 230 portion doped with at least one of quantum dot material and phosphor.

[0149] In this embodiment, the display module 10 incorporates at least one of quantum dot material and phosphor within the sealant layer 230 portion corresponding to the light conversion structure 111 in the frame region A2. This allows the light emitted by the light-emitting unit 221 to enter the sealant layer 230 corresponding to the light conversion structure 111 in the frame region A2, thereby stimulating the sealant layer 230 to emit light. Consequently, the light emitted by the sealant layer 230 corresponding to the light conversion structure 111 in the frame region A2 can counteract the effects of external moisture, oxygen, or high temperatures on the light-emitting capability of the light conversion structure 111 in the frame region A2.
