The application provides a display panel, as shown in fig. 1 to 3, the display panel includes a substrate 10, a light-emitting layer 20, a refraction layer 30, a scattering layer 40, the light-emitting layer 20 is disposed on one side of the substrate 10, the light-emitting layer 20 includes a plurality of light-emitting units 21; the refraction layer 30 is disposed on a side of the light emitting layer 20 facing away from the substrate 10, the refraction layer 30 includes a laminated first refraction sub-layer 31 and a second refraction sub-layer 32, the first refraction sub-layer 31 includes a plurality of protrusions 311 disposed corresponding to the light emitting units 21, the second refraction sub-layer 32 is disposed on a side of the light emitting layer 20 facing away from the substrate 10 and covers the first refraction sub-layer 31, and a refractive index of the first refraction sub-layer 31 is greater than a refractive index of the second refraction sub-layer 32; the scattering layer 40 is disposed on a side of the refraction layer 30 facing away from the substrate 10, and the scattering layer 40 includes scattering portions 41 correspondingly disposed between the protrusions 311, and the scattering portions 41 are configured to disperse light incident into the scattering portions 41.

In this embodiment, the display panel may be an OLED panel, mini-LED panel, micro-LED panel, or the like.

In this embodiment, the substrate 10 may be a flexible material or a rigid material, for example, the material of the flexible substrate is a reinforced plastic such as polyimide, polycarbonate, polyethersulfone, polyethylene terephthalate, polyethylene naphthalate, polyarylate, or glass fiber. The material of the rigid substrate may be glass or the like.

The display panel comprises a display area and a non-display area arranged on the periphery of the display panel, wherein the display area is provided with a plurality of sub-pixels 11, and each sub-pixel 11 is arranged corresponding to one light emitting unit 21.

The substrate 10 may be provided with an array layer provided with a driving circuit for driving the sub-pixels 11 of the display panel to emit light. Taking an OLED panel as an example, the array layer further includes a pixel defining layer 111, where the pixel defining layer 111 includes a plurality of openings, and the light emitting layer 20 is disposed in the openings. The light emitting layer 20 includes a plurality of light emitting material layers, one disposed corresponding to each sub-pixel 11. The sub-pixel 11 includes an anode 211, a light emitting material layer, and a cathode (not shown in the figure), and a driving circuit supplies driving signals to the anode 211 and the cathode, the anode 211 for supplying holes, and the cathode for supplying electrons, the holes and the electrons being recombined in the light emitting material layer to emit light.

In this embodiment, the refraction layer 30 is disposed on the light emitting layer 20, and the refraction layer 30 is used to gather the light emitted from the light emitting unit 21 onto the front view angle, so as to improve the brightness of the front view angle of the display panel. For example, the refractive layer 30 may be a microlens array, but is not limited thereto.

The refractive layer 30 comprises a first refractive sub-layer 31 and a second refractive sub-layer 32. The first refraction sublayer 31 comprises a plurality of protrusions 311, and the second refraction sublayer 32 covers the first refraction sublayer 31. The refractive index of the first refractive sub-layer 31 is greater than the refractive index of the second refractive sub-layer 32. With the above arrangement, when the light emitted from the light emitting unit 21 is incident on the interface between the first refractive sub-layer 31 and the second refractive sub-layer 32, refraction can occur, so that the emitted light is converged in the normal direction of the substrate 10, that is, the method is converged to the front view angle. The shape of the first refraction sublayer 31 is not limited in the present application, and only the first refraction sublayer 31 is required to gather the outgoing light of the light emitting unit 21 in the normal direction of the substrate 10.

It should be understood that the protrusions 311 are provided corresponding to the light emitting units 21, and the protrusions 311 may be formed by patterning. The patterning process comprises the working procedures of photoresist coating, exposure and development, etching and the like.

In this embodiment, the first refraction sublayer 31 and the second refraction sublayer 32 may be made of organic or inorganic transparent materials, so as not to affect light transmission. For example, the material of the first refractive sub-layer 31 may be a material such as silicon nitride or photoresist with a high refractive index. The material of the second refraction sublayer 32 may be a low refractive index silicon oxynitride or photoresist.

In this embodiment, the scattering layer 40 is disposed on the refraction layer 30, and the scattering layer 40 includes scattering portions 41 correspondingly disposed between the protrusions 311, where the scattering portions 41 can diffuse the light incident into the scattering portions 41, so as to achieve uniform light emission at all angles.

The front projection of the scattering portion 41 onto the substrate 10 is located between the front projections of the projections 311 onto the substrate 10, that is to say that the front projection of the scattering portion 41 onto the substrate 10 does not overlap with the front projection of the projections 311 onto the substrate 10. With the above arrangement, the scattering portions 41 can be disposed between the protrusions 311, so that the scattering portions 41 do not affect the gathering effect of the protrusions 311 on light.

Specifically, as shown in fig. 2, since the orthographic projection of the light emitting unit 21 on the substrate 10 is located within the orthographic projection of the first refraction sublayer 31 on the substrate 10, the light S1 emitted from the light emitting unit 21 perpendicular to the plane of the substrate 10 is emitted in the original direction. The light S2 emitted from the light emitting unit 21 and having a small angle with respect to the plane of the substrate 10 is emitted through the interface between the first refractive sub-layer 31 and the second refractive sub-layer 32, and is thus aligned to be directed close to the normal line of the substrate 10. The two light rays S1 and S2 can improve the brightness of the display panel at the front view angle. It will be appreciated that since part of the light S2 is directed close to the normal of the substrate 10, the light on this part of the path is missing, resulting in a too fast decay of the light brightness in this angular range.

For this, the light S3 emitted by the light emitting unit 21 and having a larger angle with the plane of the substrate 10 does not pass through the interface between the first refraction sublayer 31 and the second refraction sublayer 32, but enters the scattering layer 40 after passing through the second refraction sublayer 32, and is further scattered in different directions, so that the technical problem of too fast luminance attenuation in the side view angle is solved by compensating for the light loss in the original path of the light S2.

That is, the present embodiment can make the refractive layer 30 gather the light S2 to the front view angle and make the scattering layer 40 diverge the light S3 from the side view angle by the above arrangement, thereby improving the technical problem that the luminance on the side view angle decays too fast.

The sizes of the scattering portion 41, the first refraction sublayer 31, and the light emitting unit 21 may be set as needed to control the front brightness in different angle ranges. For example, the direction of the line connecting the centers of two adjacent light emitting units 21 is taken as the first direction D1. The pitch of the boundary of the scattering portion 41 and the first refraction sublayer 31 that are close to each other in the first direction D1 may be adjusted according to the viewing angle requirement of the display panel, and the pitch of the boundary of the adjacent two scattering portions 41 that are close to each other in the first direction D1 may be set according to the pitch of the centers of the adjacent two light emitting units 21.

For example, when the display panel satisfies the brightness increase in the 60-degree viewing angle and the light is uniform outside the 60-degree viewing angle, the angle between the line connecting the center of the light emitting unit 21 and the boundary of the scattering portion 41 and the normal line of the substrate 10 is 30 degrees, that is, θ is 30 degrees in fig. 2.

In some embodiments, the distance between the boundary of the scattering portion 41, which is close to each other, and the first refractive sub-layer 31 in the first direction D1 is 6 micrometers to 10 micrometers. The distance between the boundaries of the adjacent two scattering portions 41 in the first direction D1, which are adjacent to each other, is 13.86 micrometers or more, and the thickness from the center of the light emitting unit 21 to the upper surface of the second refractive sublayer 32 is 12 micrometers to 18 micrometers, and the above arrangement makes it possible to set the angle θ to about 30 degrees. When the angle θ is other, the size and/or the pitch of the scattering portion 41 and the first refractive sub-layer 31 may be adjusted correspondingly.

In the display panel of the present application, as shown in fig. 2, fig. 2 is a schematic view of a first cross-sectional structure at C-C in fig. 1. The scattering portion 41 includes a first light-transmitting portion 411 and a plurality of scattering particles 412 disposed between the protrusions 311, and the scattering particles 412 are distributed in the first light-transmitting portion 411.

In the present embodiment, the scattering portion 41 includes the first light-transmitting portions 411 disposed between the protrusions 311 and the scattering particles 412 distributed within the first light-transmitting portions 411. The orthographic projection of the scattering portion 41 on the refraction layer 30 is located between the protrusions 311. The material of the first light transmitting part 411 may be a transparent inorganic insulating material or an organic insulating material. For example, the first light transmitting portion 411 may be any one of silicon oxide, silicon nitride, and silicon oxynitride, but is not limited thereto.

The scattering particles 412 may be nano-sized particles. The shape of the particles may be spherical or irregular particle shape. After the light is incident on the surface of the scattering particles 412, it may be reflected, thereby changing the path of the light.

The filling ratio (Fill Factor) of the scattering particles 412 may be 2% to 20%, and in the above range, the scattering particles 412 can have a good scattering effect. When the filling ratio of the scattering particles 412 is too large, the light transmittance is lowered and the haze is deteriorated. The filling ratio refers to the ratio of the area of the orthographic projection of the scattering particles 412 on the substrate 10 to the area of the orthographic projection of the scattering portion 41 on the substrate 10.

In the display panel of the present application, as shown in fig. 3, fig. 3 is a schematic diagram of a second cross-sectional structure at C-C in fig. 1. The second display panel is different from the first display panel in the structure of the diffusion section 41. The second scattering portion 41 includes a first light-transmitting portion 411 and a diffraction structure 413 disposed between the protrusions 311, and the disposition of the first light-transmitting portion 411 can be referred to the above-described embodiments. The diffraction structure 413 includes a plurality of spaced diffraction units 4131, and the diffraction units 4131 are distributed in the first light-transmitting portion 411.

In this embodiment, the diffraction structure 413 includes a plurality of diffraction units 4131 spaced apart, the diffraction units 4131 are distributed in the first light-transmitting portion 411, the diffraction units 4131 may be arranged along a first direction D1, and the first direction D1 may be any direction parallel to the plane of the substrate 10.

Specifically, the diffraction units 4131 are periodically arranged, wherein the width of the diffraction units 4131 in the first direction D1 is D, and the distance between two adjacent diffraction units 4131 in the first direction D1 is D, and D/D is 0.3.ltoreq.d.ltoreq.1.2. By adjusting the width of the diffraction unit 4131 in the arrangement direction to D and the interval between two adjacent diffraction units 4131 to D, the intensity of diffraction can be made to satisfy the requirement of light divergence.

The diffraction structure 413 may be prepared by a photolithography process or a nanoimprinting process. The width d of the diffraction unit 4131 in the arrangement direction is less than or equal to 1 micron, thereby avoiding shielding of the light by the diffraction unit 4131 itself.

In the present embodiment, the material of the diffraction unit 4131 may be a light transmitting material such as an organic photoresist, a photoresist, or the like, but is not limited thereto.

In the display panel of the present application, as shown in fig. 2 and 3, the scattering layer 40 further includes: the second light transmitting portion 42 is disposed corresponding to the protrusion 311, and the first light transmitting portion 411 is disposed around the second light transmitting portion 42.

In the present embodiment, the second light transmitting portion 42 is provided in the same layer as the scattering portion 41. That is, the scattering portion 41 and the second light-transmitting portion 42 may be located on the same film layer. For example, when the scattering portion 41 is disposed on the second refraction sublayer 32 in contact, the second light-transmitting portion 42 may also be disposed on the second refraction sublayer 32 in contact.

In the present embodiment, the material of the second light transmitting portion 42 may be a transparent inorganic insulating material or an organic insulating material. For example, the second light transmitting portion 42 may be any one of silicon oxide, silicon nitride, and silicon oxynitride, but is not limited thereto.

The orthographic projection of the protrusion 311 on the second light-transmitting portion 42 is located in the second light-transmitting portion 42, and the light emitted from the protrusion 311 can pass through the second light-transmitting portion 42. The first light-transmitting portion 411 is disposed around the second light-transmitting portion 42, that is, the first light-transmitting portion 411 is disposed at the periphery of the second light-transmitting portion 42.

Further, in the present embodiment, the second light transmitting portion 42 and the scattering portion 41 are disposed in connection in a direction parallel to the plane of the substrate 10, and the second light transmitting portion 42 is the same material as the first light transmitting portion 411. That is, the first light-transmitting portion 411 and the second light-transmitting portion 42 are continuous and of the same material, so that no distinct interface exists between the first light-transmitting portion 411 and the second light-transmitting portion 42, and a visual difference between the two portions due to refraction and reflection of light at the interface between the first light-transmitting portion 411 and the second light-transmitting portion 42 is avoided.

Alternatively, the diffusion part 41 and the second light transmitting part 42 may be implemented by a reticle etching or a division printing process, but are not limited thereto.

In the display panel of the present application, as shown in fig. 2 and 3, the protrusion 311 includes a refracting surface 31a, at least a portion of the refracting surface 31a forms an acute angle α with the plane of the substrate 10, and the second refracting sub-layer 32 covers the refracting surface 31a.

In the present embodiment, the cross-sectional shape of the protrusion 311 may be a trapezoid, a semicircle, a semi-ellipse, or the like, but is not limited thereto. The refractive surface 31a makes an acute angle α with the plane of the substrate 10, thereby refracting light rays in a direction close to the normal of the substrate 10.

The refractive surface 31a may be a plane surface, a curved surface, or a combination of a plane surface and a curved surface. The present application is not limited to the shape of the first refractive surface 31a, and the refractive surface 31a is only required to be capable of converging the outgoing light of the light emitting unit 21 in the normal direction of the substrate 10. For example, when the cross-sectional shape of the protrusion 311 is a trapezoid, the refractive surface 31a may be a trapezoid waist, and the side wall of the protrusion 311 forms an angle α with the plane of the substrate 10.

In the display panel of the present application, the display panel includes a touch layer 50, the touch layer 50 and the first refraction sublayer 31 are arranged in the same layer, the touch layer 50 includes a plurality of touch units 51, the touch units 51 are located between two adjacent protrusions 311, the touch units 51 are arranged corresponding to the scattering portions 41, and the second refraction sublayer 32 covers the touch units 51.

In this embodiment, the touch layer 50 may be a self-capacitance touch or a mutual capacitance touch, which is not limited in the present application.

In this embodiment, the touch layer 50 is disposed on the same layer as the first refraction sublayer 31, and the touch layer 50 includes a plurality of touch units 51. The touch layer 50 may include a first metal layer and a second metal layer separated by an insulating layer, which may be the same material as the first refraction sublayer 31. The first metal layer and the second metal layer are connected through the via hole in a partial area. By arranging the touch layer 50 and the first refraction sublayer 31 in the same layer, the insulating layer between the first metal layer and the second metal layer and the first refraction sublayer 31 can be manufactured by adopting the same film forming process, so that the manufacturing process of the display panel can be simplified.

Optionally, the thickness of the touch layer 50 is 0.2 to 0.6 micrometers. The second refractive sublayer 32 may have a thickness of 1 to 5 microns. The second refractive sub-layer 32 covers the touch layer 50 and the first refractive sub-layer 31.

Further, in the present embodiment, the touch layer 50 is in a grid shape, and the orthographic projection of the touch layer 50 on the substrate 10 is located at the periphery of the orthographic projection of the light emitting unit 21 on the substrate 10, so as to prevent the touch layer 50 from shielding the light emitted by the light emitting unit 21. The orthographic projection of the touch layer 50 on the substrate 10 is located within the orthographic projection of the scattering portion 41 on the substrate 10, for example, the distance between the boundary of the orthographic projection of the touch unit 51 on the substrate 10 and the boundary of the orthographic projection of the scattering portion 41 on the substrate 10 may be greater than 1 micrometer. By providing the orthographic projection of the touch layer 50 on the substrate 10 within the orthographic projection of the scattering portion 41 on the substrate 10, the scattering portion 41 can diverge light, and therefore, the influence of the touch layer 50 on the light in the area of the scattering portion 41 is small.

In the display panel of the present application, the display panel further includes an encapsulation layer 60, the encapsulation layer 60 is disposed on a side of the light emitting layer 20 away from the substrate 10, and the encapsulation layer 60 is disposed on a side of the refraction layer 30 close to the substrate 10. That is, the encapsulation layer 60 is disposed between the light emitting layer 20 and the refraction layer 30. The encapsulation layer 60 serves to prevent intrusion of moisture or the like into the light emitting layer 20. The encapsulation layer 60 may include a stacked first encapsulation sub-layer 61, a second encapsulation sub-layer 62, and a third encapsulation sub-layer 63. The first and third encapsulation sublayers 61 and 63 may be inorganic layers, and the second encapsulation sublayer 62 may be an organic layer, but is not limited thereto.
