DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0036] In the related art, there are three solutions to reduce the reflectivity of MicroLED display screens: (1) Using black glue for packaging. This solution will cause the black glue to absorb the light emitted from the side of the chip, including the light originally emitted from the top of the chip after being reflected from the side of the chip, thereby reducing the brightness of the display screen. In addition, the light absorbed by the glue will increase the heat of the display panel, which is not conducive to the heat dissipation of the display panel; (2) Using lens glue and circular polarizer packaging. This solution causes the circular polarizer to not only absorb the reflected ambient light, but also absorb more than 55% of the light emitted by the chip, resulting in a decrease in brightness or an increase in power consumption in order to increase the brightness; (3) Making a patterned BM (black matrix) layer on the cover plate and making a light hole at the position of the Micro LED chip. This solution requires a precise bonding process and has a high preparation cost.

[0037] [First embodiment]

[0038] To make up for at least some of the defects in the above-mentioned related solutions, the first embodiment of the present invention provides a display panel 100. An array substrate 10, a lens 20, a reflective layer 30 and a light shielding layer 40. Figure 1The array substrate 10 includes a back plate 11 and a display unit 12 disposed on the back plate 11. The lens 20 protrudes from the back plate 11 and wraps the display unit 12. The reflective layer 30 covers the side of the back plate 11 facing the display unit 12 and covers the lens 20. The reflective layer 30 has a first opening 31, which is located on the side of the lens 20 facing away from the back plate 11 and exposes one end of the lens 20 facing away from the back plate 11. The light shielding layer 40 covers the side of the reflective layer 30 facing away from the back plate 11; the light shielding layer 40 has a second opening 41, which is arranged corresponding to the first opening 31 and exposes the first opening 31.

[0039] The display unit 12 is, for example, a Micro LED chip, wherein one display unit 12 may include one Micro LED chip or multiple Micro LED chips, such as Figure 1 A display unit 12 shown in the figure includes a MicroLED chip. However, in some other embodiments, when the distance between multiple MicroLED chips is set relatively close, multiple MicroLED chips can be regarded as one display unit 12. For example, multiple pixels are arranged on the backplane 11, and each pixel includes multiple color sub-pixels, for example, and MicroLED chips of different colors are arranged in the multiple color sub-pixels. For example, light-emitting devices of three colors, R (red), G (green), and B (blue), can be arranged. The MicroLED chip in the blue sub-pixel can be regarded as one display unit 12, the MicroLED chip in the green sub-pixel can be regarded as one display unit 12, and the MicroLED chip in the red sub-pixel can be regarded as one display unit 12. Or, for example, a main light-emitting device and a redundant light-emitting device are also arranged in each sub-pixel, and the main light-emitting device and the redundant light-emitting device can be regarded as one display unit 12. For example, a driving circuit for driving the display unit 12 to emit light and a binding electrode for binding and welding the display unit 12 are arranged on the backplane 11. The display units 12 can be electrically connected to the corresponding driving circuits through the binding electrodes on the backplane 11. For example, a plurality of display units 12 are disposed on the back panel 11, and the plurality of display units 12 are disposed at intervals from each other. Figure 1 As shown in the dimension mark, the distance from the surface of the display unit 12 facing away from the back plate 11 (i.e., the top surface of the display unit 12) to the back plate 11 is the fourth height H4. The display unit 12 has a second width W2, wherein when the display unit 12 is a MicroLED chip, the second width W2 may be the maximum width of the MicroLED chip, and when the display unit 12 includes a plurality of MicroLED chips, the second width W2 is the diameter of the circumscribed circle of the plurality of MicroLED chips in the display unit 12.

[0040] The lens 20 can be made of a transparent organic material such as a transparent resin. The lens 20 forms a raised curved surface structure, forming a convex lens effect, which can focus the light emitted by the display unit 12. The area where the lens 20 contacts the back panel 11 can be called a light-emitting area. If there are multiple display units 12, then there are also multiple lenses 20. The multiple lenses 20 are arranged one-to-one corresponding to the multiple display units 12, that is, each lens 20 wraps a display unit 12, and the multiple lenses 20 are arranged at intervals from each other. Figure 1 As shown in the size mark, the height of the lens 20 protruding from the back plate 11 is the second height H2, wherein the fourth height H4 is less than the second height H2. The side of the lens 20 close to the back plate 11 has a third width W3. For example, if the surface of the lens 20 in contact with the back plate 11 is circular, the third width W3 is the diameter of the circle in contact with the back plate 11. The third width W3 is greater than the second width W2. The material of the reflective layer 30 can be selected as a highly reflective material with a reflectivity of more than 80%. In some embodiments, the reflective layer 30 is, for example, a metal reflective layer, which can be one or more of Ag (silver), Al (aluminum), Mo (molybdenum), Cu (copper), Au (gold), and Ti (titanium). The portion of the back plate 11 other than the lens 20 can be called a non-luminous area. The reflective layer 30 covers the non-luminous area and covers part of the outer surface of the lens 20 (the surface of the lens 20 facing away from the display unit 12). When there are multiple lenses 20, there are also multiple first openings 31. The multiple first openings 31 are arranged in a one-to-one correspondence with the multiple lenses 20, so that at the position of each display unit 12, after the reflective layer 30 reflects the light from the side of the display unit 12, the lens 20 focuses the light and emits it through the first opening 31. The light emitted from the side of the display unit 12 can be fully utilized, and the light output efficiency can be improved. When the reflective layer 30 is a metal reflective layer, it can be prepared by a vapor deposition process, and the first opening 31 can be formed by an etching process. The multiple lenses 20 are arranged at intervals from each other, and the side of the reflective layer 30 facing away from the back plate 11 forms a first gap portion 32 located between the multiple lenses 20. The first gap portion 32 includes multiple first gaps, and a first gap is formed between any two adjacent lenses 20. The thickness of the reflective layer 30 is, for example, Figure 1 h1 shown in FIG. The distance from the first opening 31 to the back plate 11 is the fifth height H5. The fifth height H5 is less than the second height H2. In some embodiments, the fourth height H4 is greater than the fifth height H5. The first opening 31 has a first width W1. If the shape of the first opening 31 is, for example, circular, the first width W1 is the diameter of the first opening 31. When the first opening 31 is of other shapes, the minimum width of the first opening 31 can be regarded as the first width W1. In some embodiments, the first width W1 is greater than the second width W2. In some embodiments, the first width W1 is less than the third width W3.

[0041] In some embodiments, Figure 2 As shown, the surface of the lens 20 facing away from the display unit 12 is covered with a transition layer 60. The transition layer 60 is located between the lens 20 and the reflective layer 30. The transition layer 60 may be, for example, SiO x (Silicon Oxide), SiN x (silicon nitride) and other inorganic transparent materials. It can increase the adhesion between the reflective layer 30 and the lens 20 and prevent the reflective layer 30 from peeling off. The thickness of the transition layer 60 is, for example, greater than 0.2 μm (micrometer).

[0042] In some embodiments, reference Figure 2 , the display panel 100 further includes a limiting structure 70, which is arranged around the lens 20 on one side close to the back plate 11. When the number of lenses 20 is multiple, the number of limiting structures 70 can also be multiple, and the multiple limiting structures 70 correspond to each other around the multiple lenses 20, that is, each limiting structure 70 surrounds one lens 20. The setting of the limiting structure 70 can limit the material forming the lens 20 during the formation process of the lens 20, ensure the thickness of the lens 20 wrapped around the outside of the display unit 12, and also ensure the distance between the reflective layer 30 and the display unit 12. In some embodiments, the distance e1 between the limiting structure 70 and the display unit 12 wrapped in the corresponding lens 20 is 5 to 15 microns, which can better achieve the light gathering and side light reflection effects, improve the light energy utilization rate, and reduce power consumption.

[0043] The light shielding layer 40 may be made of a material with a reflectivity lower than 5%. In some embodiments, the light shielding layer 40 is, for example, a black adhesive material, which may be made by adding graphite powder to an organic adhesive material; or the light shielding layer 40 may be made of a black metal material with a low reflectivity, such as MoO x (Molybdenum oxide) material; or in some embodiments, the light shielding layer 40 may include a transparent medium layer and a Mo layer sequentially stacked on the reflective layer 30, and the transparent medium layer may be a metal oxide or SiO x (Silicon Oxide), SiN x(silicon nitride), etc. The light shielding layer 40 covers the side of the reflective layer 30 facing away from the back plate 11, so that the light from the external environment is absorbed but not reflected when it enters the light shielding layer 40, thereby reducing the reflectivity of the display panel 100 and improving the display effect. The second opening 41 is arranged corresponding to the first opening 31. If there are multiple first openings 31, there are also multiple second openings 41. Multiple second openings 41 are arranged one-to-one with multiple first openings 31 to expose the first opening 31, so that the light emitted by each display unit 12 can be emitted to the outside of the display panel 100 through the first opening 31 and the second opening 41 to achieve the display effect. The second opening 41 has a fourth width W4. The second opening 41 is, for example, circular, and the fourth width W4 is the diameter of the second opening 41. If the second opening 41 is of other shapes, the minimum width of the second opening 41 can be regarded as the fourth width W4. The fourth width W4 can be greater than or equal to the first width W1. The fourth width W4 is less than the third width W3.

[0044] In some embodiments, the light shielding layer 40 fills the first gap 32 to form Figure 1 and Figure 2 The structure shown in FIG. On the one hand, the light shielding layer 40 can achieve the effect of reducing the reflectivity, and on the other hand, it also enables the display panel 100 to form a flat surface. Figure 1 and Figure 2 In the embodiment shown, reference is made to Figure 1 In the dimension mark in FIG. 1 , the distance from the surface of the light shielding layer 40 facing away from the back plate 11 (i.e., the top surface of the light shielding layer 40) to the surface of the reflective layer 30 is the thickness h2 of the light shielding layer 40. The distance from the surface of the light shielding layer 40 facing away from the back plate 11 to the back plate 11 is the first height H1, and the first height H1=h1+h2. In some embodiments, the first height H1 is greater than the second height H2.

[0045] In other embodiments, Figure 3 and Figure 4 As shown, the side of the light shielding layer 40 facing away from the back plate 11 forms a second gap portion 42 located between the plurality of lenses 20. The second gap portion 42 includes a plurality of second gaps, and one second gap is formed between any two adjacent lenses 20. Figure 3 and Figure 4 The display panel 100 shown further includes a protective layer 50, which fills the second gap 42. The surface of the display panel 100 can be made flat to protect the display panel 100. The protective layer 50 is, for example, a transparent protective layer. The distance from the surface of the protective layer 50 facing away from the back plate 11 (i.e., the top surface of the protective layer 50) to the light shielding layer 40 (i.e., the thickness of the protective layer 50) is h3. The height from the surface of the protective layer 50 facing away from the back plate 11 (i.e., the top surface of the protective layer 50) to the back plate 11 is a third height H3, and the third height H3=h1+h2+h3. In some embodiments, the third height H3 is greater than the second height H2.

[0046] In summary, the display panel 100 provided in this embodiment can reflect the side light of the display unit 12 through the reflective layer 30 and emit it through the first opening 31 and the second opening 41 after focusing through the lens 20, so that the side light of the display unit 12 can be fully utilized to improve the front light emission efficiency. In addition, the light shielding layer 40 can reduce the reflectivity of the display panel 100 and improve the display effect.

[0047] [Second embodiment]

[0048] like Figures 5 to 8 As shown, the second embodiment of the present invention provides a method for preparing a display panel, which can be used to prepare the display panel 100 provided by the first embodiment. The method for preparing a display panel includes steps S1 to S5.

[0049] S1: providing an array substrate 10, wherein the array substrate 10 comprises a back plate 11 and a display unit 12 disposed on the back plate 11;

[0050] Lens forming step S2: forming a lens 20 on the display unit 12 that protrudes from the back plate 11 and wraps the display unit 12;

[0051] Reflective material layer forming step S3: forming a reflective material layer 33 on a side of the back plate 11 facing the display unit 12 and a surface of the lens 20 facing away from the display unit 12;

[0052] Light shielding material layer forming step S4: forming a light shielding material layer 43 on the side of the reflective layer 30 facing away from the back plate 11;

[0053] Opening forming step S5: S(5.1): forming a first opening 31 on the reflective material layer 33 to obtain a reflective layer 30; the first opening 31 is located on the side of the lens 20 facing away from the back plate 11 and exposes one end of the lens 20 facing away from the back plate 11; S(5.2): forming a second opening 41 on the shading material layer 43 to obtain a shading layer 40; wherein the second opening 41 is arranged corresponding to the first opening 31 and exposes the first opening 31.

[0054] In step S1, for example, the light emitting device (Micro LED chip) in the display unit 12 is bonded to the back plate 11 by welding or the like to obtain Figure 5 The array substrate 10 shown in step (a) of FIG. 1 . The number of the display units 12 may be multiple.

[0055] In some specific embodiments, step S2 may, for example, use a transparent organic material to form a lens 20 through dispensing or embossing. When there are multiple display units 12, multiple lenses 20 are formed in step S2 corresponding to the multiple display units 12, and the multiple lenses 20 are spaced apart from each other. Each display unit 12 is wrapped by a lens 20. Step S3, for example, specifically uses a metal evaporation process to form a reflective material layer 33. The material forming the reflective material layer 33 can be a highly reflective metal material, for example, one or a combination of Ag (silver), Al (aluminum), Mo (molybdenum), Cu (copper), Au (gold), and Ti (titanium). After step S3, it can be obtained Figure 5 In the structure of step (c), the side of the reflective material layer 33 facing away from the back plate 11 forms a first gap portion 32 located between the plurality of lenses 20. A first gap is formed between any two adjacent lenses 20, and the first gap portion 32 includes a plurality of first gaps.

[0056] Reference Figure 6 , before step S2, for example, step S8 is also included: forming a limiting structure 70 around the display unit 12 on the back plate 11, obtaining Figure 6 The number of the limiting structures 70 may correspond to multiple, and in step S8, one limiting structure 70 may be formed for each display unit 12. The limiting structure 70 may be formed, for example, by using a transparent adhesive material through an inkjet printing process. In step S2, a lens 20 may be formed in the limiting structure 70 by using a dispensing process, and the following may be obtained: Figure 6 The structure shown in step (k). The limiting structure 70 can limit the material forming the lens 20 during the formation process of the lens 20, ensure the thickness of the lens 20 wrapped around the outside of the display unit 12, and also ensure the distance between the reflective layer 30 and the display unit 12. It can better achieve the light gathering and side light reflection effects, improve the light energy utilization rate, and reduce power consumption.

[0057] After step S2 and before step S3, for example, the method further includes step S6: forming a transition layer 60 on the surface of the lens 20 facing away from the display unit 12. Figure 5 The transition layer 60 may be, for example, SiO x (Silicon Oxide), SiN x (silicon nitride) and other inorganic transparent materials. Since the lens 20 is made of organic materials, if the reflective material layer 33 is formed directly on the outer side of the lens 20 by a metal evaporation process, the high temperature during the formation process may cause the material of the lens 20 to expand, thereby causing the reflective material layer 33 to peel off. Providing the transition layer 60 can enhance the adhesion between the reflective material layer 33 and the lens 20 and prevent the reflective material layer 33 from falling off.

[0058] The light shielding material layer 43 can be formed by, for example, a black glue material. Then, step S4 includes, for example, step S41: filling the light shielding layer material (black glue material) into the first gap 31 to form the light shielding material layer 43. After step S41, Figure 7 Then, step S (5.2) is performed to form a second opening 41 on the light shielding material layer 43 by etching process, so as to form Figure 7 The structure shown in step (e) is obtained to obtain the light shielding layer 40. Finally, step S (5.1) is performed to form a first opening 31 on the reflective material layer 33 by etching to obtain the reflective layer 30. The position of the first opening 31 is opposite to the position of the second opening 41, forming Figure 7 The structure of step (f) is obtained, that is, the display panel 100 is obtained.

[0059] The light shielding material layer 43 can be formed of a black metal material, for example. Then step S4 specifically includes step S42: covering the light shielding material layer 43 on the reflective material layer 33 by using an evaporation process. Figure 8 In the structure shown in step (g), the side of the light shielding material layer 43 formed after step S42 facing away from the back plate 11 forms a second gap portion 42 located between the multiple lenses 20, and a second gap is formed between any two adjacent lenses 20, and the second gap portion 42 includes multiple second gaps. Then the display panel preparation method also includes step S7: forming a protective layer 50 in the second gap portion 42. Step S7 can be obtained by coating the second gap portion 42 with a transparent material. Figure 8 After completing step S7, an etching process is used to simultaneously perform step S(5.2) and step S(5.1) to simultaneously form the first opening 31 and the second opening 41, and obtain the structure shown in step (h). Figure 8 The structure shown in step (i) is obtained, that is, the display panel 100 is obtained.
