Description

Technical Field

[0001] The present application belongs to the field of display technology, and specifically relates to a method for manufacturing a diffusion plate and a display device. Background Art

[0002] At present, liquid crystal displays are dominant in flat panel display technology, and transmissive liquid crystal displays are the mainstream of current liquid crystal display technology. Since liquid crystal displays themselves do not emit light, backlight modules are essential for transmissive liquid crystal displays. Generally speaking, backlight modules can be divided into edge-lit and direct-lit types.

[0003] The direct-type backlight module is composed of a light source, a back panel and a diffusion plate. Currently, there are two main methods to solve the display problem of the direct-type backlight module: increasing the content of the diffuser in the diffusion plate and adding a reflective coating on the surface of the diffusion plate.

[0004] Among them, increasing the content of the diffusant in the diffuser plate, the higher the content of the diffusant, the lower the transmittance of the diffuser plate, the higher the haze, which can increase the reflectivity of light and expand the area of ​​the light spot, but the method of increasing the diffusant has the problem of low light efficiency; adding a reflective coating on the surface of the diffuser plate can increase the reflectivity, but this method has no obvious effect on the brightness prompt.

DETAILED DESCRIPTION

[0080] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of example embodiments to those skilled in the art.

[0081] According to a first aspect of an embodiment of the present application, a method for manufacturing a diffusion plate 100 is provided. The diffusion plate 100 manufactured by the manufacturing method is applied to a display device.

[0082] Among them, see Figure 1 and Figure 2As shown, the display device includes a backlight module and a display panel 200. The backlight module may be a direct-down structure, which includes a back plate 300, a light-emitting element 400 and the above-mentioned diffusion plate 100. The light-emitting element 400 is disposed on the back plate 300. The light-emitting element 400 may be an LED light source, a miniLED light source or a micro LED light source. The diffusion plate 100 is disposed on the back plate 300 and is arranged opposite to the light-emitting element 400. One side of the diffusion plate 100 receives the light emitted by the light-emitting element 400, and the other side corresponds to the display panel 200, that is, the diffusion plate 100 diffuses the light emitted by the light-emitting element 400 and then emits it to the display panel 200 to complete the display image.

[0083] See also Figure 1 and Figure 2 As shown, the diffuser plate 100 includes a light guide grid 101 and a diffuser plate body 102. The light guide grid 101 is arranged on one side of the diffuser plate body 102 close to the light emitting element 400. When the light emitted by the light emitting element 400 enters the light guide grid 101, the light will diffuse to various angles and then enter the diffuser plate body 102 to diffuse again. The diffuser plate body 102 is filled with a diffusing agent, which can increase the diffusion effect of the light.

[0084] It should be noted that the use of this light guide mesh 101 can improve the haze of the diffuser 100, so as to improve the reflectivity of the light and expand the spot area, and then the method of reducing the use of the diffusant content in the diffuser body 102 to increase the haze of the diffuser 100 can also reduce the content of the diffusant in the diffuser body 102, improve the transmittance of the diffuser 100, further improve the light effect, and then improve the display brightness. In addition, this light guide mesh 101 can correspond to the light-emitting element 400 one by one, that is, one light-emitting element 400 corresponds to one light guide mesh 101. It can also be that multiple light guide meshes 101 correspond to one light-emitting element 400. It can also be that the side of the diffuser body 102 close to the light-emitting element 400 uses light guide meshes 101 with different density and size distribution, and the density and size of the light guide meshes 101 at the position corresponding to the light-emitting element 400 are larger, so as to solve the problem of light shadow and further improve the display effect.

[0085] Among them, see Figure 3 As shown, the manufacturing method of the diffuser plate 100 includes the following steps:

[0086] Step S100, providing a screen substrate 500, on which a plurality of groups of transparent portions are disposed, the plurality of groups of transparent portions are disposed at intervals on the screen substrate 500, and each group of transparent portions includes at least two layers of transparent regions 5000, see Figure 4a or Figure 5a .

[0087] Step S200, providing a diffusion plate body 102, such as Figure 4b or Figure 5b The diffuser body 102 is filled with a diffuser, which can improve the diffusion effect of light.

[0088] Step S300, the screen substrate 500 is attached to one side of the diffuser body 102, such as Figure 4c or Figure 5c shown.

[0089] Step S400, filling ink into the transparent area, such as Figure 4d or Figure 5d shown.

[0090] Step S500, curing the ink in the transmission area;

[0091] Step S600, removing the screen substrate 500 and forming a light guide grid point 101 with the same outline as the transmission area on one side of the diffuser plate body 102. The light guide grid point is a three-dimensional structure extending toward the side away from the diffuser plate body, see Figure 4e or Figure 5e shown.

[0092] It is worth mentioning that the transparent parts are evenly arranged on the screen substrate 500, and the transparent parts are spaced apart from each other; each group of transparent parts includes at least two layers of transparent areas 5000, which are penetrating areas with a hollow structure that allows liquid to flow through the transparent areas. The above-mentioned light-guiding dots 101 can be formed on the diffuser plate body 102 through the transparent areas 5000.

[0093] In addition, see Figure 4a or Figure 5a As shown, in the direction from the light emitting element 400 to the display panel 200 , the transmission area of ​​the transmission region 5000 gradually increases, and the transmission area of ​​the transmission region 5000 close to the display panel 200 is larger than the transmission area of ​​the transmission region 5000 close to the light emitting element 400 .

[0094] For example, when each group of dot through holes includes two layers of transmission areas 5000, in the direction from the light-emitting element 400 to the display panel 200, the transmission area of ​​the first layer of transmission area 5000 close to the light-emitting element 400 is smaller than the transmission area of ​​the second layer of transmission area 5000, and the first layer of transmission area 5000 is located on the side close to the display panel 200, and the second layer of transmission area 5000 is located on the side close to the transmission area 5000 of the light-emitting element 400.

[0095] The screen substrate 500 includes at least two screen bodies, and the screen bodies are stacked, that is, the screen bodies are stacked on each other; each screen body is provided with a transmission area 5000, and the transmission areas 5000 on the screen bodies correspond to each other. In the direction from the light emitting element 400 to the display panel 200, the transmission area on the transmission area 5000 gradually increases; that is, the transmission area of ​​the transmission area 5000 close to the diffuser plate body 102 is greater than the transmission area of ​​the transmission area 5000 far from the diffuser plate body 102.

[0096] That is, the screen substrate 500 is formed by superimposing at least two screen bodies, and each screen body is provided with a transmission area 5000. The transmission areas 5000 on all the screen bodies correspond to each other, and in the direction from the light emitting element 400 to the display panel 200, the transmission area of ​​the transmission area 5000 gradually increases, and the transmission area of ​​the transmission area 5000 close to the diffuser plate body 102 is greater than the transmission area of ​​the transmission area 5000 far from the diffuser plate body 102.

[0097] For example, the screen substrate 500 includes two screen bodies stacked together, namely, a first screen body 501 and a second screen body 502. The first screen body 501 and the second screen body 502 are respectively provided with a first transmission area 503 and a second transmission area 504. The first transmission area 503 on the first screen body 501 and the second transmission area 504 on the second screen body 502 correspond to each other. In the direction from the light-emitting element 400 to the display panel 200, the transmission area of ​​the transmission area gradually increases, that is, the transmission area of ​​the first transmission area 503 is greater than the area of ​​the second transmission area 504. The first screen body 501 is arranged on the side of the second screen body 502 close to the diffuser body 102.

[0098] By stacking at least two screen bodies to form the screen substrate 500, it is easier to design different sizes of transmission areas, and the design is simpler, which simplifies the design method of different transmission areas. It should be noted that the transmission area of ​​the transmission area on each screen body can be gradual or constant. In the embodiment of the present application, in each screen body: the transmission area of ​​the transmission area is the same to ensure the uniformity of its diffusion effect.

[0099] In some embodiments, in the direction from the display panel 200 to the light emitting element 400 , in each mesh body: the transmission area of ​​the transmission region gradually decreases; it can be understood that the cross-section of the transmission region in the thickness direction of the diffuser plate 100 is a trapezoidal structure.

[0100] In the examples of this application, see Fig.9eAs shown, the screen substrate 500 includes a first screen body 501 and a second screen body 502, which are stacked in sequence in the thickness direction of the diffuser plate body 102. The transmittance area of ​​the transmittance region of the first screen body 501 is greater than the transmittance area of ​​the transmittance region of the second screen body 502. When the screen substrate 500 is attached to the diffuser plate body 102, the side of the first screen body 501 away from the second screen body 502 is attached to the diffuser plate body 102. In other words, the first screen body 501 with a larger transmittance area is attached to the side of the diffuser plate body 102 close to the light-emitting element 400. It can be understood that the light-guiding mesh point 101 on the diffuser body 102 can be formed by the transparent area on the first mesh body 501 and the transparent area on the second mesh body 502. By adopting a three-dimensional structure with different light-guiding areas, the haze of the diffuser 100 can be improved, and the content of the diffuser in the diffuser 100 can be reduced, and the absorption of light by the diffuser in the diffuser 100 can be reduced. Moreover, the light-guiding mesh point 101 is composed of two different parts, which can improve the diffusion effect of light, improve the light efficiency, and thus improve the display effect. Figure 6 and Figure 8 As shown, the method of forming the screen substrate 500 using the first screen body 501 and the second screen body 502 includes:

[0101] Step S110, providing a first mesh 710, and coating a layer of resin on the first mesh 710, such as Figure 7a shown.

[0102] Step S111, providing a first bottom film 601, on which first shielding areas 602 are arranged, and the first shielding areas 602 are arranged at intervals on the first bottom film 601, such as Figure 7b It is understandable that the first shielding area 602 can be printed on the first film 601 by the above-mentioned printing method.

[0103] Step S112, the first mesh 710 coated with resin is arranged opposite to the first base film 601, such as Figure 7c The first bottom film 601 with the first shielding area 602 is arranged opposite to the first mesh 710 coated with resin, and the first shielding area 602 has an overlapping area on the first mesh 710 .

[0104] Step S113, curing the resin on the first mesh 710 that is not blocked by the first blocking area 602, such as Figure 7dAs shown. The resin on the first mesh 710 is cured by ultraviolet rays (UV). The first shielding area 602 can shield the ultraviolet rays, while the ultraviolet rays can pass through the position on the first film 601 where the first shielding area 602 is not present to cure the resin on the first mesh 710. In other words, the resin on the first mesh 710 that overlaps with the first shielding area 602 will not be cured by the ultraviolet rays, while the resin that does not overlap with the first shielding area 602 will be cured by the ultraviolet rays and become hard.

[0105] Step S114, washing the first mesh 710 to remove the uncured resin, forming the first transparent area 503 at the position of the first mesh 710 corresponding to the first shielding area 602, and forming the first mesh body 501, as shown in FIG. Figure 7e It is understandable that the uncured resin on the first mesh 710 can be removed by washing with water, that is, the resin at the position corresponding to the first shielding area 602 is removed by washing with water, while the cured resin on the rest of the first mesh 710 will not be washed away by water, so as to obtain the first transparent area 503 and form the first mesh body 501, as shown in FIG7 .

[0106] Step S115, laying a layer of second mesh 720 on the first mesh 710, and coating a layer of resin on the second mesh 720, such as Figure 9a That is, after the first mesh body 501 is formed, a second mesh gauze 720 is laid on the first mesh body 501, and then the second mesh body 502 is formed.

[0107] In some embodiments, the first mesh body 501 and the second mesh body 502 may be designed separately, that is, the first mesh body 501 and the second mesh body 502 are designed separately, and then the first mesh body 501 and the second mesh body 502 are attached.

[0108] Step S116, providing a second bottom film 603, on which a second shielding area is provided, the second shielding area is arranged at intervals on the second bottom film 603, and the second shielding area includes a first shielding portion 604 and a second shielding portion 605 arranged at intervals, such as Figure 9b As shown. It is understandable that the second shielding area can print the first shielding portion 604 and the second shielding portion 605 on the second film 603 by the above-mentioned printing method. Step S117, the second mesh 720 coated with resin is arranged opposite to the second film 603, and the first mesh 710 is arranged on the side of the second mesh 720 away from the second film 603, as shown in FIG. Fig.9c shown.

[0109] Step S118 solidifies the resin on the second mesh 720 that is not blocked by the first blocking portion 604 and the second blocking portion 605. Figure 9d As shown. The negative film with the second shielding area is arranged opposite to the second mesh 720 coated with resin, and the second shielding area has an overlapping area on the second mesh 720, and the overlapping area corresponds to the first transparent area 503, and the overlapping area is smaller than the area of ​​the first transparent area 503, so as to ensure the stability of the resin on the first mesh body 501. The resin on the second mesh 720 is cured by ultraviolet light (UV). Among them, the first shielding part 604 and the second shielding part 605 on the second shielding area can block the ultraviolet light, and the ultraviolet light can pass through the position where the first shielding part 604 and the second shielding part 605 are not present on the second negative film 603, and cure the resin on the second mesh 720. In other words, the resin on the second mesh 720 that has an overlapping area with the first shielding part 604 and the second shielding part 605 in the second shielding area will not be cured by ultraviolet light, while the resin that has no overlapping area with the first shielding part 604 and the second shielding part 605 in the second shielding area will be cured by ultraviolet light and become hard.

[0110] Step S119, washing the second mesh 720 to remove the uncured resin, forming a second transparent area 504 at the position of the second mesh 720 corresponding to the second shielding area, the second transparent area 504 corresponds to the first transparent area 503, and the transparent area of ​​the second transparent area 504 is smaller than the transparent area of ​​the first transparent area 503, forming a second mesh body 502, as shown in FIG. Fig.9e shown.

[0111] It is understandable that, since the structure of the second shielding area is different from that of the first shielding area 602, the second shielding area adopts two first shielding parts 604 and second shielding parts 605 which are spaced apart from each other, and the first shielding area 602 is an integral structure. Therefore, when the resin on the second mesh 720 is irradiated with ultraviolet rays, the resin corresponding to the first shielding part 604 and the second shielding part 605 will not be cured, and the resin between the first shielding part 604 and the second shielding part 605 in the second shielding area will be cured because the resin between the first shielding part 604 and the second shielding part 605 on the second mesh 720 is not shielded from ultraviolet rays. When the second mesh 720 is washed with water, the uncured resin is removed, and a second transparent area 504 is formed on the second mesh 720. Among them, since the first blocking portion 604 and the second blocking portion 605 are arranged at an interval, there is solidified resin in the second transparent area 504 in the second mesh 720. Due to the effect of the second mesh 720, the resin will not fall off, and the transparent area of ​​the second transparent area 504 is smaller than the transparent area of ​​the first transparent area 503.

[0112] It should be noted that the cross-sectional area of ​​the first shielding area 602 in the thickness direction of the first bottom film 601 is a rectangular or square structure, and the cross-sectional area of ​​the second shielding area in the thickness direction of the second bottom film 603 is a rectangular or square structure. Finally, the formed screen substrate 500 has a first transparent area 503 and a second transparent area 504, the first transparent area 503 and the second transparent area 504 are connected to each other, and the first transparent area 503 and the second transparent area 504 are hollow structures.

[0113] The method of forming light-guiding dots by using a screen substrate formed of two screen bodies includes: attaching a first screen body 501 to a diffuser body 102, and arranging a second screen body 502 on a side of the first screen body 501 away from the diffuser body 102, and filling ink into the second transmission area 504. Since the second transmission area 504 and the first transmission area 503 are interconnected, the ink in the second transmission area 504 will gradually flow into the first transmission area 503 and contact the side of the diffuser body 102 close to the light-emitting element 400. Then, the ink filled in the first transmission area 503 and the second transmission area 504 is cured by ultraviolet irradiation to form a light-guiding dot 101 on the side of the diffuser body 102 close to the light-emitting element 400. The light-guiding dot 101 has the same contour as the first transmission area 503 and the second transmission area 504, see Figure 4c and Figure 4e shown.

[0114] like Figure 4e As shown, the light guide dot 101 includes a first light guide portion 110 formed by a first transmission area 503 and a second light guide portion 111 formed by a second transmission area 504. The second light guide portion 111 is disposed on a side of the first light guide portion 110 close to the diffuser plate body 102. The second light guide portion 111 includes a first portion 120 and a second portion 121. The first portion 120 corresponds to the first shielding portion 604, and the second portion 121 corresponds to the second shielding portion 605. That is, the first portion 120 and the second portion 121 are arranged at intervals and extend in a direction away from the first light guide portion 110. It is worth mentioning that, since there is solidified resin in the second transmission area 504 of the second screen body 502, when filling ink, the solidified resin will block the formation of ink, and ink is only filled around the solidified resin. The solidified resin separates the ink in the second transmission area 504 from each other, and finally forms the first light guide portion 110 and the second light guide portion 111.

[0115] It is understandable that if Figure 4eAs shown, the first light guide part 110 and the second light guide part 111 form a light guide grid point 101 similar to a crater shape. Since the light guide grid point 101 is at a higher height in the direction from the light emitting element 400 to the diffuser plate body 102, that is, the light guide grid point 101 is thicker, the overall haze of the diffuser plate 100 can be improved, and the shielding property is better, and the content of the diffusing agent inside the diffuser plate body 102 can be reduced. In other words, the diffusing agent inside the diffuser plate body 102 is reduced by using the light guide grid point 101, thereby reducing the absorption of light by the diffuser plate body 102, increasing the transmittance, improving the light effect, optimizing the display effect, and improving the optical brightness.

[0116] In some other embodiments, see Figure 5a As shown, the screen substrate 500 includes a third screen body 505, a fourth screen body 506 and a fifth screen body 507, which are stacked in sequence. In the direction from the light-emitting element 400 to the display panel 200, the transmission areas of the third screen body 505, the fourth screen body 506 and the fifth screen body 507 gradually increase. When the screen substrate 500 is attached to the diffuser plate body 102, the third screen body 505 is attached to the diffuser plate body 102.

[0117] That is, the transmission area of ​​the third network version body 505 is greater than the transmission area of ​​the fourth network version body 506, and the transmission area of ​​the fourth network version body 506 is greater than the transmission area of ​​the fifth network version body 507. Fig.10 , Fig.12 and Fig.14 As shown, the method of forming the screen substrate 500 includes:

[0118] Step S120, providing a third mesh 730, and coating a layer of resin on the third mesh 730, such as Fig.11a Step S121, providing a third bottom film 606, on which a third shielding area 607 is provided, and the third shielding area 607 is arranged at intervals on the third bottom film 606, as shown in FIG. Fig.11b It is understandable that the third shielding area 607 can be printed on the third negative film 606 by the above-mentioned printing method.

[0119] Step S122, the third mesh 730 coated with resin is arranged opposite to the third bottom film 606, such as Fig.11c Step S123, curing the resin on the third mesh 730 that is not blocked by the third blocking area 607, as shown in FIG. Fig.11dAs shown. The third base film 606 with the third shielding area 607 is arranged opposite to the third mesh 730 coated with resin, and the third shielding area 607 has an overlapping area on the third mesh 730. The resin on the third mesh 730 is cured by ultraviolet rays (UV). Among them, the third shielding area 607 can block the ultraviolet rays, and the ultraviolet rays can pass through the position on the third base film 606 where there is no third shielding area 607 to cure the resin on the third mesh 730. In other words, the resin on the third mesh 730 that has an overlapping area with the third shielding area 607 will not be cured by ultraviolet rays, while the resin that does not have an overlapping area with the third shielding area 607 will be cured by ultraviolet rays and become hard.

[0120] Step S124, washing the third mesh 730 to remove the uncured resin, and forming the third transparent area 508 at the position corresponding to the third shielding area 607 of the third mesh 730, thereby forming the third mesh body 505, as shown in FIG. Fig.11e It is understandable that the uncured resin on the third mesh 730 can be removed by washing with water, that is, the resin at the position corresponding to the third shielding area 607 is removed by washing with water, while the cured resin on the rest of the third mesh 730 will not be washed away by water, so as to obtain the third transparent area 508 and form the third mesh body 505.

[0121] Step S125, laying a layer of fourth mesh 740 on the third mesh 730, and coating a layer of resin on the fourth mesh 740, such as Fig.13a That is, after the third mesh body 505 is formed, a fourth mesh gauze 740 is laid on the third mesh body 505, and then the fourth mesh body 506 is formed.

[0122] Step S126, providing a fourth bottom film 608, on which fourth shielding areas 609 are provided, and the fourth shielding areas 609 are arranged at intervals on the fourth bottom film 608, such as Fig.13b As shown. It can be understood that the fourth shielding area 609 can be printed on the fourth film 608 by the above-mentioned printing method, and the shielding area of ​​the fourth shielding area 609 is smaller than the shielding area of ​​the third shielding area 607. Step S127, the fourth mesh 740 coated with resin is arranged opposite to the fourth film 608, and the third mesh 730 is arranged on the side of the fourth mesh 740 away from the fourth film 608, as shown in FIG. Fig.13c shown.

[0123] Step S128 solidifies the resin on the fourth mesh 740 that is not blocked by the fourth blocking area 609. Fig.13dAs shown. The fourth film 608 with the fourth shielding area 609 is arranged opposite to the fourth mesh 740 coated with resin, and the fourth shielding area 609 has an overlapping area on the fourth mesh 740. The resin on the fourth mesh 740 is cured by ultraviolet rays (UV). Among them, the fourth shielding area 609 can block the ultraviolet rays, and the ultraviolet rays can pass through the position on the fourth film 608 where there is no fourth shielding area 609 to cure the resin on the fourth mesh 740. In other words, the resin on the fourth mesh 740 that has an overlapping area with the fourth shielding area 609 will not be cured by ultraviolet rays, while the resin that does not have an overlapping area with the fourth shielding area 609 will be cured by ultraviolet rays and become hard.

[0124] Step S129, washing the fourth mesh 740 to remove the uncured resin, and forming the fourth transparent area 509 at the position corresponding to the fourth shielding area 609 of the fourth mesh 740, thereby forming the fourth mesh body 506. Fig.13e It is understandable that the uncured resin on the fourth mesh 740 can be removed by washing with water, that is, the resin at the position corresponding to the fourth shielding area 609 is removed by washing with water, while the cured resin on the rest of the fourth mesh 740 will not be washed away by water, so as to obtain the fourth transparent area 509 and form the fourth mesh body 506.

[0125] Step S130, laying a layer of fifth mesh 750 on the fourth mesh 740, and coating a layer of resin on the fifth mesh 750, such as Fig.15a That is, after the fourth mesh body 506 is formed, a layer of fifth mesh gauze 750 is laid on the fourth mesh body 506 , and then the fifth mesh body 507 is formed, and the fourth mesh body 506 is arranged between the third mesh body 505 and the fifth mesh body 507 .

[0126] Step S131, providing a fifth bottom film 610, on which fifth shielding areas 611 are provided, and the fifth shielding areas 611 are arranged at intervals on the fifth bottom film 610, such as Fig.15b It is understood that the fifth shielding area 611 can be printed on the fifth film 610 by the above printing method. In addition, the cross-sectional area of ​​the fifth shielding area 611 on the fifth film 610 is smaller than the cross-sectional area of ​​the fourth shielding area 609 on the fourth film 608.

[0127] Step S132, the fifth mesh 750 coated with resin is arranged opposite to the fifth base film 610, and the fourth mesh 740 is arranged on the side of the fifth mesh 750 away from the fifth base film 610, such as Fig.15c shown.

[0128] Step S133 solidifies the resin on the fifth mesh 750 that is not blocked by the fifth blocking area 611. Fig.15d As shown. The fifth base film 610 with the fifth shielding area 611 is arranged opposite to the fifth mesh 750 coated with resin, and the fifth shielding area 611 has an overlapping area on the fifth mesh 750. The resin on the fifth mesh 750 is cured by ultraviolet rays (UV). Among them, the fifth shielding area 611 can block the ultraviolet rays, and the ultraviolet rays can pass through the position on the fifth base film 610 where there is no fifth shielding area 611, and cure the resin on the fifth mesh 750. In other words, the resin on the fifth mesh 750 that has an overlapping area with the fifth shielding area 611 will not be cured by ultraviolet rays, while the resin that does not have an overlapping area with the fifth shielding area 611 will be cured by ultraviolet rays and become hard.

[0129] Step S134, washing the fifth mesh 750 to remove the uncured resin, and forming the fifth transparent area 510 at the position corresponding to the fifth shielding area 611 of the fifth mesh 750, thereby forming the fifth mesh body 507, as shown in FIG. Fig.15e As shown. It can be understood that the uncured resin on the fifth mesh 750 can be removed by washing with water, that is, the resin at the position corresponding to the fifth shielding area 611 can be removed by washing with water, while the cured resin on the rest of the fifth mesh 750 will not be washed away by water, so as to obtain the fifth transmission area 510 and form the fifth mesh body 507. It is worth mentioning that since the transmission area of ​​the third mesh body 505 is larger than the transmission area of ​​the fourth mesh body 506, and the transmission area of ​​the fourth mesh body 506 is larger than the transmission area of ​​the fifth mesh body 507, when the fourth mesh body 506 and the fifth mesh body 507 are subsequently cured by ultraviolet light, the third transmission area 508 and the fourth transmission area 509 in the third mesh body 505 and the fourth mesh body 506 will not be affected.

[0130] The method of forming light-guiding dots by using a screen substrate formed of three screen bodies includes: attaching the third screen body 505 to the diffusion plate body 102, stacking the fourth screen body 506 and the fifth screen body 507 in sequence, and placing the fourth screen body 506 between the third screen body 505 and the fifth screen body 507, and filling the fifth transmission area 510 with ink. Since the fifth transmission area 510, the fourth transmission area 509 and the third transmission area 508 are interconnected, the ink in the fifth transmission area 510 will gradually The ink gradually flows to the fourth transmission area 509, and then flows to the third transmission area 508, and contacts the side of the diffuser plate body 102 close to the light emitting element 400. The ink in the third transmission area 508, the fourth transmission area 509 and the fifth transmission area 510 is cured by ultraviolet irradiation to form a light guide grid point 101 on the side of the diffuser plate body 102 close to the light emitting element 400. The light guide grid point 101 has the same contour as the third transmission area 508, the fourth transmission area 509 and the fifth transmission area 510. Figure 5c and Figure 5e It should be noted that the cross-sectional shape of the light guide dots 101 in the thickness of the diffuser body 102 is stacked, and because the transmission area of ​​the third transmission area 508, the transmission area of ​​the fourth transmission area 509 and the transmission area of ​​the fifth transmission area 510 gradually decrease, the cross-sectional area of ​​the light guide dots 101 close to the light emitting element 400 is the smallest.

[0131] For example, the light guide network dot 101 includes a third light guide portion 112 formed by a third transmission area 508, a fourth light guide portion 113 formed by a fourth transmission area 509, and a fifth light guide portion 114 formed by a fifth transmission area 510. The fourth light guide portion 113 is disposed between the third light guide portion 112 and the fifth light guide portion 114. The third light guide portion 112 is disposed on a side of the fourth light guide portion 113 away from the light emitting element 400. In the direction from the light emitting element 400 to the display panel 200, the cross-sectional areas of the fifth light guide portion 114, the fourth light guide portion 113, and the third light guide portion 112 in the thickness direction of the diffuser plate body 102 gradually increase, as shown in FIG. Figure 5e shown.

[0132] In addition, the projections of the third light guide portion 112, the fourth light guide portion 113 and the fifth light guide portion 114 on the diffuser plate body 102 are triangular or circular, that is, the formed third light guide portion 112 can be a triangular prism or cylindrical structure. It is worth mentioning that in some embodiments, the screen substrate 500 can also adopt a multi-layer screen body structure, and in the direction from the diffuser plate body 102 to the light-emitting element 400, the transmission area of ​​the transmission area in the multi-layer screen body gradually decreases.

[0133] In a second aspect of the embodiment of the present application, a display device is provided. The display device includes a backlight module and a display panel 200. The display panel 200 is arranged on the light emitting side of the backlight module. Figure 1 and Figure 2 As shown, the backlight module includes a light-emitting element 400 and a diffuser plate 100 manufactured by any of the above-mentioned manufacturing methods, the diffuser plate 100 is arranged on the light-emitting side of the light-emitting element 400, and the display panel 200 is arranged on the side of the diffuser plate 100 away from the light-emitting element 400; the diffuser plate 100 includes a diffuser plate body 102 and light-guiding dots 101, and a plurality of light-guiding dots 101 are arranged on the side of the diffuser plate body 102 close to the light-emitting element 400, and the light-guiding dots 101 include at least two layers of light-guiding portions, and in the direction from the light-emitting element 400 to the display panel 200, the cross-sectional area of ​​the at least two layers of light-guiding portions in the thickness direction of the diffuser plate body 102 gradually increases.

[0134] The present application can improve the diffusion effect of the diffuser plate 100 by adopting light-guiding dots 101 with thicker thickness and different shapes, and can reduce the content of the diffuser in the diffuser plate body 102, thereby reducing the absorption of light by the diffuser, and can improve the transmittance of light, optimize the display effect, enhance the optical brightness, and thus improve the display effect of the display device.

[0135] Among them, see Figure 1 and Figure 4e As shown, the light guide mesh point 101 can be a light guide mesh point 101 in a crater-like shape formed by the first mesh body 501 and the second mesh body 502. It can be understood that the light guide mesh point 101 formed by the first mesh body 501 and the second mesh body 502 presents a shape with the same contour as the first transmission area 503 and the second transmission area 504. Among them, the second light guide part 111 is arranged on the side of the first light guide part 110 close to the diffuser plate body 102, and the second light guide part 111 includes a first part 120 and a second part 121. The first part 120 corresponds to the above-mentioned first shielding part 604, and the second part 121 corresponds to the above-mentioned second shielding part 605, that is, the first part 120 and the second part 121 are arranged at intervals from each other and extend in a direction away from the first light guide part 110. It is worth mentioning that due to the presence of solidified resin in the second transparent area 504 of the second screen body 502, when filling ink, the solidified resin will block the formation of ink, and ink will only be filled around the solidified resin. The solidified resin separates the ink in the second transparent area 504 from each other, and finally forms the first light guide portion 110 and the second light guide portion 111.

[0136] It can be understood that the first light guide portion 110 and the second light guide portion 111 form a three-dimensional structure, and the light guide dots 101 thereof are relatively high in the direction from the light emitting element 400 to the diffuser plate body 102, that is, the light guide dots 101 are relatively thick, which can improve the overall haze of the diffuser plate 100, have better shielding properties, and can reduce the content of the diffusing agent inside the diffuser plate body 102. In other words, the light guide dots 101 are used to reduce the amount of diffusing agent inside the diffuser plate body 102, thereby reducing the absorption of light by the diffuser plate body 102, increasing the transmittance, improving the light efficiency, optimizing the display effect, and improving the optical brightness. The light guide dots may also be stacked light guide dots 101 formed by the third mesh body 505, the fourth mesh body 506, and the fifth mesh body 507, such as Figure 2 and Figure 5e The cross-sectional shape of the light guide dots 101 in the thickness of the diffuser plate body 102 is stacked, and because the transmission area of ​​the third transmission area 508, the fourth transmission area 509 and the fifth transmission area 510 gradually decrease, the cross-sectional area of ​​the light guide dots 101 close to the light emitting element 400 is the smallest.

[0137] For example, the light guide network dot 101 includes a third light guide portion 112 formed by a third transmission area 508, a fourth light guide portion 113 formed by a fourth transmission area 509, and a fifth light guide portion 114 formed by a fifth transmission area 510. The fourth light guide portion 113 is disposed between the third light guide portion 112 and the fifth light guide portion 114. The third light guide portion 112 is disposed on a side of the fourth light guide portion 113 away from the light emitting element 400. In the direction from the light emitting element 400 to the display panel 200, the cross-sectional areas of the fifth light guide portion 114, the fourth light guide portion 113, and the third light guide portion 112 in the thickness direction of the diffuser plate body 102 gradually increase, as shown in FIG. Figure 5e shown.

[0138] In addition, the projections of the third light guide part 112, the fourth light guide part 113 and the fifth light guide part 114 on the diffuser plate body 102 are triangular or circular, that is, the formed third light guide part 112 can be a triangular prism or cylindrical structure. It should be noted that the light guide grid point 101 is filled with diffusion particles, and the diffusion particles can improve the diffusion effect of light. In addition, the light guide grid point 101 can also adopt a three-dimensional structure formed by multiple light guide parts, and in the direction from the light emitting element 400 to the diffuser plate body 102, the cross-sectional area of ​​the light guide part in the thickness direction of the diffuser plate body 102 gradually increases.

[0139] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application. Therefore, any changes or modifications made in accordance with the claims and description of the present application should fall within the scope of the patent of this application.
