Description

Display panel and display device Technical Field

[0001] This application relates to the field of displays, and in particular to a display panel and display device. Background Technology

[0002] MicroLED technology has gained increasing attention in recent years due to its advantages of high brightness, high transmittance, and high contrast. However, display panels with MicroLED chips typically have a color resist layer on the light-emitting side. As the light emitted by the MicroLED chip passes through the color resist layer, some of the light is filtered out, resulting in lower transmittance and greater light loss for the display panel. Invention Overview

[0003] This application provides a display panel and display device to improve the technical problem of low transmittance of existing display panels.

[0004] To address the above issues, the technical solution provided in this application is as follows:

[0006] Substrate;

[0007] An array layer is disposed on one side of the substrate;

[0008] A light-emitting layer is disposed on the side of the array layer away from the substrate. The light-emitting layer includes a plurality of light-emitting devices spaced apart, the plurality of light-emitting devices including a first light-emitting device, a second light-emitting device, and a third light-emitting device, wherein the first light-emitting device, the second light-emitting device, and the third light-emitting device emit different colors; and

[0009] A color resist layer is disposed on the side of the light-emitting layer away from the substrate. The color resist layer includes a plurality of color resist units spaced apart. Each color resist unit corresponds to a light-emitting device. The plurality of color resist units include a first color resist unit and a second color resist unit.

[0010] In this configuration, a first color resist unit corresponds to a first light-emitting device, a second color resist unit corresponds to a second light-emitting device, and the color of the first color resist unit is the same as the light-emitting color of the first light-emitting device, and the color of the second color resist unit is the same as the light-emitting color of the second light-emitting device.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] Furthermore, the terms "first" and "second" are used 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, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0027] Please refer to Figures 1 to 11. This application proposes a display panel 100, which includes a substrate 110, an array layer 120 disposed on one side of the substrate 110, a light-emitting layer 130 disposed on the side of the array layer 120 away from the substrate 110, a light-receiving layer 140 disposed on the side of the light-emitting layer 130 away from the substrate 110, and a color resist layer 150 disposed on the side of the light-emitting layer 130 away from the substrate 110.

[0028] In this embodiment, the light-emitting layer 130 includes a plurality of light-emitting devices D arranged at intervals, and the color resist layer 150 includes a plurality of color resist units 151 arranged at intervals. Each color resist unit 151 corresponds to a light-emitting device D, and the color of the color resist unit 151 is the same as the light-emitting color of the light-emitting device D.

[0029] It should be noted that the multiple light-emitting devices D in this application may include multiple first light-emitting devices D1, multiple second light-emitting devices D2, and multiple third light-emitting devices D3, and the light-emitting colors of the first light-emitting devices D1, the second light-emitting devices D2, and the third light-emitting devices D3 are different; for example, the light-emitting colors of the first light-emitting devices D1 and the second light-emitting devices D2 are either red or blue, and the light-emitting color of the third light-emitting device D3 is green.

[0030] In this embodiment, the first light-emitting device D1 emits red light, and the second light-emitting device D2 emits blue light.

[0031] It should be noted that the multiple first light-emitting devices D1, multiple second light-emitting devices D2 and multiple third light-emitting devices D3 can be arranged in a standard RGB arrangement, for example, the first light-emitting devices D1, the second light-emitting devices D2 and the third light-emitting devices D3 set at intervals can be used as repeating units, and these repeating units can be repeatedly arranged on the display panel 100.

[0032] It should be noted that the first light-emitting device D1, the second light-emitting device D2, and the third light-emitting device D3 can all be MicroLEDs.

[0033] Please refer to Figure 1. The multiple color resist units 151 in the color resist layer 150 include a first color resist unit 151R and a second color resist unit 151B. A first color resist unit 151R corresponds to a first light-emitting device D1, and a second color resist unit 151B corresponds to a second light-emitting device D2. The color of the first color resist unit 151R is the same as the light-emitting color of the first light-emitting device D1, and the color of the second color resist unit 151B is the same as the light-emitting color of the second light-emitting device D2.

[0034] It should be noted that since the first light-emitting device D1 emits red light and the second light-emitting device D2 emits blue light, the first color resist unit 151R of this application is red and the second color resist unit 151B is blue.

[0035] This application provides color resist units 151 with the same color as the emitted light on the first light-emitting device D1 and the second light-emitting device D2, while not providing a corresponding color resist unit 151 on the third light-emitting device D3. The reduction of color resist units 151 means that some of the light emitted by the light-emitting device D does not need to pass through the color resist units 151, thereby reducing the light loss of the light emitted by the light-emitting device D and improving the transmittance of the display panel 100.

[0036] It should be noted that, since the light emission pattern of MicroLED chips is close to that of Lambertian light, a light-collecting structure is usually required to converge the light emission pattern of the LED so that most of the light is emitted from the frontal direction, thereby increasing the brightness in the frontal direction and highlighting the high-brightness display characteristics of MicroLED. Referring to Figure 1, the light-collecting layer 140 includes a plurality of light-collecting structures 141 arranged at intervals. One light-collecting structure 141 is disposed between two adjacent light-emitting devices D, and a color resist unit 151 is disposed between two adjacent light-collecting structures 141.

[0037] The technical solution of this application will now be described in conjunction with specific embodiments.

[0038] Please refer to Figure 2. The substrate 110 can be made of materials such as glass, quartz, or polyimide.

[0039] Referring to Figure 2, the array layer 120 may include multiple thin-film transistors. The thin-film transistors may be etch-block type, back-channel etch type, or classified as bottom-gate thin-film transistors, top-gate thin-film transistors, etc., depending on the position of the gate and active layer 120C. For example, a bottom-gate thin-film transistor may include a buffer layer 120H on the substrate 110, a gate layer 120A on the buffer layer 120H, a gate insulating layer 120B on the gate layer 120A, an active layer 120C on the gate insulating layer 120B, an interlayer insulating layer 120G on the active layer 120C, a source-drain layer 120D on the interlayer insulating layer 120G, a planarization layer 120E on the source-drain layer 120D, a pixel electrode layer 120F on the planarization layer 120E, and a light-emitting layer 130 on the pixel electrode layer 120F. The light-emitting device D in the light-emitting layer 130 is electrically connected to the pixel electrode layer 120F.

[0040] Alternatively, referring to Figure 3, the bottom-gate thin-film transistor type thin-film transistor may include a buffer layer 120H on the substrate 110, a gate layer 120A on the buffer layer 120H, a gate insulating layer 120B on the gate layer 120A, an active layer 120C on the gate insulating layer 120B, an inter-insulating layer 120G on the active layer 120C, a source-drain layer 120D on the inter-insulating layer 120G, and a light-emitting layer 130 on the source-drain layer 120D. The source-drain layer 120D may include bonding terminals, and the light-emitting device D in the light-emitting layer 130 is electrically connected to the bonding terminals in the source-drain layer 120D.

[0041] Please refer to Figure 1. The display panel 100 also includes a first encapsulation layer 160 disposed on the side of the array layer 120 away from the substrate 110. The first encapsulation layer 160 is used to fill the area between two adjacent light-emitting devices D, that is, multiple light-emitting devices D are embedded in the first encapsulation layer 160.

[0042] In this embodiment, the material of the first encapsulation layer 160 may include inorganic insulating material or organic insulating material.

[0043] In this embodiment, the thickness of the first encapsulation layer 160 can be the same as the thickness of the light-emitting device D.

[0044] Referring to Figure 1, the light-collecting layer 140 can be disposed on the surface of the first encapsulation layer 160 away from the substrate 110, and the light-collecting structure 141 is disposed between two adjacent light-emitting devices D. Referring to Figure 4, the multiple light-collecting structures 141 of this application can be strip-shaped, and the multiple light-collecting structures 141 are arranged in a crisscross pattern to form multiple receiving cavities, and each receiving cavity contains a light-emitting device D.

[0045] This application provides a light-collecting layer 140 comprising multiple light-collecting structures 141 on the side of the light-emitting layer 130 away from the substrate 110. The multiple light-collecting structures 141 are interwoven and form a mesh structure. Each light-emitting device D is located within a mesh of the mesh structure. This allows the light emitted by the light-emitting device D to be reflected by the sidewalls of the light-collecting structures 141, forming light at a small angle. Since the light-collecting structures 141 have high reflectivity, the light energy loss caused by the conversion of light angle in the light-collecting structures 141 is small, thereby improving the light efficiency of the display panel 100 in the positive viewing angle direction and improving the luminous efficiency of the light-emitting device D.

[0046] In this embodiment, the light-collecting structure 141 can be made of a material with a reflectivity greater than or equal to 70%, for example, the material of the light-collecting structure 141 can be a photoresist material.

[0047] In this embodiment, the light-collecting structure 141 is trapezoidal. The width L1 of the lower base of the light-collecting structure 141 can be 10μm to 20μm, the width L2 of the upper base of the light-collecting structure 141 can be 5μm to 15μm, and the height H of the light-collecting structure 141 can be 5μm to 10μm.

[0048] In this embodiment, the minimum distance between the edge of the light-emitting device D and the adjacent light-receiving structure 141 is 1 μm to 10 μm; for example, the distance between each edge of the first light-emitting device D1 and the lower edge of the adjacent light-receiving structure 141 is 5 μm, and the distance between each edge of the second light-emitting device D2 and the lower edge of the adjacent light-receiving structure 141 is 5 μm.

[0049] Please refer to Figure 1. The display panel 100 also includes a second encapsulation layer 170 disposed on the side of the first encapsulation layer 160 away from the substrate 110. The second encapsulation layer 170 fills the area between the light-collecting layer 140 and two adjacent light-collecting structures 141, which is equivalent to multiple light-collecting structures 141 being embedded in the second encapsulation layer 170.

[0050] In this embodiment, in order to ensure the flatness of the interface, the second encapsulation layer 170 needs to completely cover the multiple light-collecting structures 141, that is, the thickness of the second encapsulation layer 170 is greater than the thickness of the light-collecting structures 141; for example, the thickness of the second encapsulation layer 170 is 1 μm to 2 μm greater than the thickness of the light-collecting structures 141.

[0051] In this embodiment, the refractive index of the first encapsulation layer 160 can be equal to the refractive index of the second encapsulation layer 170, and the refractive index of both the first encapsulation layer 160 and the second encapsulation layer 170 can be between 1.45 and 1.65.

[0052] Referring to Figure 1, the color resist layer 150 can be disposed on the surface of the second encapsulation layer 170 away from the substrate 110, and one end of the first color resist unit 151R overlaps with the surface of a light-collecting structure 141 away from the substrate 110, and the other end of the first color resist unit 151R overlaps with the surface of another light-collecting structure 141 away from the substrate 110, and the orthographic projection of the first light-emitting device D1 on the color resist layer 150 is located within the first color resist unit 151R; at the same time, one end of the second color resist unit 151B overlaps with the surface of a light-collecting structure 141 away from the substrate 110, and the other end of the second color resist unit 151B overlaps with the surface of another light-collecting structure 141 away from the substrate 110, and the orthographic projection of the second light-emitting device D2 on the color resist layer 150 is located within the second color resist unit 151B.

[0053] In the structures of Figures 1 and 5, this application provides a color resist unit 151 with the same emission color as the corresponding light-emitting device D between two adjacent light-receiving structures 141. After the ambient light passes through the color resist unit 151, it forms monochromatic light with the same emission color as the corresponding light-emitting device D, thereby filtering out interfering light in the ambient light and reducing the reflectivity of the display panel 100 surface.

[0054] Meanwhile, since the color resist unit 151 also filters the light emitted by the light-emitting device D, the red color resist has a smaller effect on filtering red light and the blue color resist has a smaller effect on filtering blue light. Therefore, this application can set the corresponding color resist unit 151 on the first light-emitting device D1 and the second light-emitting device D2. However, since the green color resist has a larger effect on filtering the green light emitted by the third light-emitting device D3, the light loss of the green light emitted by the third light-emitting device D3 is greater than the benefit of reducing reflectivity. Therefore, this application only sets the first color resist unit 151R and the second color resist unit 151B to minimize the light loss of the light emitted by the light-emitting device D while reducing the surface reflectivity of the display panel 100.

[0055] It should be noted that, in order to ensure the transmittance of the color resist unit 151 to the light emitted by the light-emitting device D, the absolute value of the difference between the peak wavelength of the transmittance spectrum of the color resist unit 151 and the peak wavelength of the light emitted by the corresponding light-emitting device D is less than or equal to 1 nm.

[0056] For example, in Figure 6, curve S1 is the transmittance curve of blue light of different wavelengths by the blue color resist unit 151, curve S2 is the transmittance curve of red light of different wavelengths by the red color resist unit 151, curve S3 is the transmittance curve of blue light emitted by the first light-emitting device D1 at different wavelengths, and curve S4 is the transmittance curve of red light emitted by the second light-emitting device D2 at different wavelengths.

[0057] The absolute value of the difference between the peak wavelength of the transmittance spectrum of the red color resist unit 151 and the peak wavelength of the red light emitted by the first light-emitting device D1 is less than or equal to 1 nm, and the absolute value of the difference between the peak wavelength of the transmittance spectrum of the blue color resist unit 151 and the peak wavelength of the blue light emitted by the second light-emitting device D2 is less than or equal to 1 nm.

[0058] Please refer to Figure 6. The spectral peak width of the transmittance of the color resist unit 151 is greater than the spectral peak width of the light emitted by the corresponding light-emitting device D; that is, the spectral peak width of the transmittance of the red color resist unit 151 is greater than the spectral peak width of the red light emitted by the first light-emitting device D1, and the spectral peak width of the transmittance of the blue color resist unit 151 is greater than the spectral peak width of the blue light emitted by the second light-emitting device D2.

[0059] In this embodiment, the red color resist unit 151 has a transmittance of 85% or more for the red light emitted by the first light-emitting device D1, and the blue color resist unit 151 has a transmittance of 85% or more for the blue light emitted by the second light-emitting device D2.

[0060] It should be noted that since multiple light-collecting structures 141 enclose and form multiple accommodating cavities, the color resist unit 151 needs to cover the opening of the accommodating cavity away from the substrate 110, that is, the color resist unit 151 needs to at least partially overlap with the light-collecting structure 141 that forms the accommodating cavity.

[0061] In the structure of Figure 1, since the first color resist unit 151R and the second color resist unit 151B only partially overlap with the corresponding light-receiving structure 141, and there is still a part of the light-receiving structure 141 exposed, the present application can provide a light-shielding layer 152 on the light-receiving structure 141 to block the exposed light-shielding light-receiving structure 141.

[0062] Please refer to Figure 1. The display panel 100 also includes a light-shielding layer 152 disposed in the same layer as the color resist layer 150. The light-shielding layer 152 includes a plurality of light-shielding units BM, and the light-shielding units BM are disposed on one side of a color resist unit 151. A light-shielding unit BM corresponds to a light-collecting structure 141. The orthographic projection of the light-shielding unit BM on the light-collecting layer 140 is located in the surface of the corresponding light-collecting structure 141 on the side away from the substrate 110.

[0063] Please refer to Figure 7. The light-shielding unit BM can be strip-shaped, and multiple light-shielding units BM can form a mesh structure. The orthographic projection of multiple light-shielding units BM on the light-collecting layer 140 can be located within the mesh structure formed by multiple light-collecting structures 141.

[0064] It should be noted that, since the first color resist unit 151R overlaps with the light-collecting structure 141 corresponding to the first light-emitting device D1, and the second color resist unit 151B overlaps with the light-collecting structure 141 corresponding to the second light-emitting device D2, and the side of the light-collecting structure 141 surrounding the third light-emitting device D3 that is far from the third light-emitting device D3 is only provided with the first color resist unit 151R and the second color resist unit 151B, the width of the light-shielding unit BM between the third light-emitting device D3 and the first light-emitting device D1 or the second light-emitting device D2 in this application can be greater than the width of the light-shielding unit BM between the first light-emitting device D1 and the second light-emitting device D2.

[0065] In some embodiments, all the light-shielding units BM may have the same width.

[0066] It should be noted that the material of the light-shielding unit BM in this application can be a black photoresist material.

[0067] Please refer to Figures 1 and 5. In this application, a color resist unit 151 and a light-shielding unit BM are disposed on the side of the light-emitting layer 130 away from the substrate 110. Ambient light is converted into monochromatic light with the same color as the light emitted by the corresponding light-emitting device D after passing through the color resist unit 151. At the same time, the light-shielding unit BM is disposed so that the light incident on the surface of the light-receiving structure 141 away from the substrate 110 is absorbed, which further reduces the reflectivity of the display panel 100.

[0068] Please refer to Figure 1. In order to further increase the light at the viewing angle of the display panel 100, the display panel 100 also includes at least one light-concentrating layer 180 disposed on the side of the light-receiving layer 140 away from the substrate 110. The light-concentrating layer 180 includes a plurality of microlens structures. A light-emitting device D corresponds to at least one microlens structure. The microlens structure can be a plurality of protrusions on the side away from the substrate 110, used to convert the light incident on the light-concentrating layer 180 into light perpendicular to the light-emitting surface.

[0069] In this embodiment, the material of the light-concentrating layer 180 can be polyethylene terephthalate (PET) or polymethyl methacrylate (PMMA).

[0070] Referring to Figure 1, the display panel 100 of this application also includes an anti-reflection layer 190 disposed on the side of the light-concentrating layer 180 away from the substrate 110. The anti-reflection layer 190 in this application can be an AR (Anti-Reflection) film, mainly used to reduce the reflectivity of the surface of the display panel 100.

[0071] Please refer to Figures 8 and 9. The structure in Figure 8 is the same as or similar to the structure in Figure 1. The difference is that the first color resist unit 151R and the second color resist unit 151B are both located on the side of the light-concentrating layer 180 away from the substrate 110, and the orthogonal projection of the first light-emitting device D1 on the color resist layer 150 is located in the first color resist unit 151R, and the orthogonal projection of the second light-emitting device D2 on the color resist layer 150 is located in the second color resist unit 151B.

[0072] Compared to the structure in Figure 1, in Figure 8, the color resist layer 150 and the light-shielding layer 152 are not disposed on the same layer, and the color resist layer 150 is disposed on the side of the light-collecting layer 180 away from the substrate 110. In the structure of Figure 8, since the color resist layer 150 and the light-shielding layer 152 are not disposed on the same layer, the light-shielding unit BM and the surface of the corresponding light-collecting structure 141 away from the substrate 110 can completely overlap, while the color resist unit 151 can at least partially overlap with the light-shielding unit BM.

[0073] Please refer to Figures 8 and 9. Since ambient light is reflected in each film layer of the display panel 100, this embodiment provides the color resist layer 150 on the side of the light-concentrating layer 180 away from the substrate 110. This allows ambient light to be directly incident into the color resist layer 150 without passing through the light-concentrating layer 180, thereby converting the ambient light into monochromatic light. This reduces the ambient light reflected in the display panel 100 and further reduces the reflectivity of the display panel 100.

[0074] Please refer to Figure 10. The structure in Figure 10 is the same as or similar to the structure in Figure 1. The difference is that the light-shielding layer 152 is disposed on the side of the light-receiving layer 140 near the substrate 110. The light-shielding layer 152 includes multiple light-shielding units BM, and a light-shielding unit BM is disposed between two adjacent light-emitting devices D.

[0075] Compared to the structure in Figure 1, the structure in Figure 10 moves the light-shielding layer 152 down to the surface of the array layer 120 and sets it in the same layer as the light-emitting layer 130, and forms a light-shielding material in the entire area except for the light-emitting device D.

[0076] In this embodiment, since the array layer 120 has a large number of metal layers, and the metal layers have a high reflectivity to ambient light, this application provides a light-shielding layer 152 on the surface of the array layer 120 to prevent ambient light from being reflected by the metal in the array layer 120 and affecting the reflectivity of the display panel 100.

[0077] Please refer to Figure 11. The structure in Figure 11 is the same as or similar to the structure in Figure 1, except that: the first color resist unit 151R is disposed on the side wall of the two adjacent light-receiving structures 141 facing the first light-emitting device D1, and the second color resist unit 151B is disposed on the side wall of the two adjacent light-receiving structures 141 facing the second light-emitting device D2.

[0078] Compared with the structure in Figure 1, in this embodiment, the color resist layer 150 is moved downward, and each color resist unit 151 is disposed on the side wall of the light-collecting structure 141 located around the light-emitting device D; for example, taking the first color resist unit 151R as an example, the first light-collecting device D1 is provided with a ring of light-collecting structure 141 around it, and the first color resist unit 151R will be formed on the side wall of the ring of light-collecting structure 141 facing the first light-emitting device D1.

[0079] The increase in reflectivity of the display panel 100 is mainly due to the reflection of ambient light incident on the surface of the light-collecting structure 141. This application reduces the reflectivity of the display panel 100 by forming a color resist unit 151 on the sidewall of the light-collecting structure 141 and setting a light-shielding unit BM on the surface of the light-collecting structure 141 away from the substrate 110. This allows ambient light to be converted into monochromatic light or absorbed by the light-shielding unit BM when it passes through the light-collecting structure 141.

[0080] The following comparative experiments were conducted to compare the reflectivity and light loss rate of the display panel 100 of this application.

[0081] In Comparative Example 1, based on Figure 1, a green color resist unit 151 is provided on the third light-emitting device D3, which is on the same layer as the first color resist unit 151R and the second color resist unit 151B; the reflectivity of the display panel 100 in Comparative Example 1 is 6%, and the light loss rate is 10% to 30%.

[0082] In Comparative Example 2, taking the structure in Figure 1 as an example, the reflectivity of the display panel 100 in Comparative Example 2 is 6%, and the light loss rate is 5%.

[0083] In Comparative Example 3, the light-shielding layer 152 was removed from Comparative Example 1; the reflectivity of the display panel 100 in Comparative Example 3 was 7.5%, and the light loss rate was 10%.

[0084] In Comparative Example 4, the light-shielding layer 152 was removed from Comparative Example 2; the reflectivity of the display panel 100 in Comparative Example 4 was 10.5%, and the light loss rate was 5%.

[0085] According to the above four sets of comparative examples, in Comparative Examples 2 and 4, the light loss rate did not increase, but the setting of the light-shielding layer 152 increased the reflectivity of the display panel 100 from 6.5% to 10.5%. In Comparative Examples 1 and 2, removing the green color resist increased the reflectivity by 0.5%, but reduced the light loss rate to 5%. Therefore, by adding the light-shielding layer 152 and removing the green color resist, this application ensures the light loss rate of the display panel 100 while reducing the reflectivity.
