As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In general display devices, a plurality of microscopic concave-convex lenses are formed on the concave-convex surface of the anti-glare cover plate, and the structure of the concave-convex lenses makes a light beam directly incident easily focus, so that a snowflake sparkling point (sparkle) is formed, and the visual effect is influenced.
Referring to fig. 1, a display device 10 according to an embodiment of the present disclosure includes a display module 110, a cover plate 120 disposed on the display module 110, an anti-glare structure 121 disposed on a surface of the cover plate 120 away from the display module 110, and a light scattering structure 160 disposed between the cover plate 120 and the display module 110, wherein the anti-glare structure 121 includes a first concave-convex surface 1210 away from the cover plate 120, and the light scattering structure 160 includes a second concave-convex surface 1610 away from the cover plate 120.
When external light irradiates on the anti-glare structure 121 of the display device 10, the first concave-convex surface 1210 can realize diffuse reflection on the external light, and the light is prevented from being excessively concentrated during reflection, so that an anti-glare effect is realized. Meanwhile, when the light emitted by the display module 110 irradiates the light scattering structure 160, the second concave-convex surface 1610 can scatter the light of the display module 110, that is, the light passing through the second concave-convex surface 1610 has a divergence characteristic, so as to avoid the direct irradiation of the light on the first concave-convex surface 1210, thereby reducing the phenomenon of snowflake sparkling points and improving the visual effect.
In some embodiments, the anti-glare structure 121 is integrally formed with the cover plate 120, and at this time, the first concave-convex surface 1210 is a surface of the cover plate 120 away from the display module 110. In other embodiments, the anti-glare structure 121 is a separate film-like structure, that is, the anti-glare structure 121 further includes a first connection surface 1220 opposite to the first concave-convex surface 1210, and at this time, the anti-glare structure 121 is connected to the surface of the cover plate 120 away from the display module 110 through the first connection surface 1220. The anti-glare structure 121 may be made of plastic or glass, and the cover plate 120 may also be made of plastic or glass.
In some embodiments, the first concave-convex surface 1210 of the anti-glare structure 121 may be formed by etching a side of the cover plate 120 away from the display module 110, and at this time, the cover plate 120 and the anti-glare structure 121 are integrally formed. In other embodiments, an adhesive layer may be formed on the side of the cover plate 120 away from the display module 110, and then the first concave-convex surface 1210 of the anti-glare structure 121 is formed by stamping or the like. In still other embodiments, the anti-glare structure 121 is a separate thin film, and the first concave-convex surface 1210 is formed on the surface of the thin film away from the cover plate 120 by etching or the like.
Specifically, in some embodiments, the anti-glare structure 121 includes a plurality of first protrusions 1211 arranged at intervals, and the plurality of first protrusions 1211 form the first concave-convex surface 1210 of the anti-glare structure 121. The width of the cross section of the first protrusion 1211 gradually increases in a direction from the cover plate 120 to the display module 110, wherein the cross section is perpendicular to the anti-glare structure 121. Specifically, in some embodiments, the first protrusion 1211 may have any one of a cone, a pyramid, a hemisphere, a semi-ellipsoid, and a rhomboid. In some embodiments, the first concave-convex surface 1210 may be formed by forming a plurality of first protrusions 1211 on the anti-glare structure 121 by an embossing or etching method. At this time, light irradiated from the outside to the first concavo-convex surface 1210 is diffusely reflected by the plurality of first protrusions 1211.
Referring to fig. 1 and 2, in some embodiments, the light diffusion structure 160 includes a second connection surface 1620 opposite to the second concave-convex surface 1610, in the light diffusion structure 160, the second concave-convex surface 1610 is close to the display module 110, and the second connection surface 1620 is far from the display module 110. In some embodiments, the light scattering structure 160 connects adjacent elements by a second connecting surface 1620.
In some embodiments, the light diffusion structure 160 is formed by an optical adhesive, which may be an ultraviolet curing adhesive, an ultraviolet curing resin, an infrared curing adhesive, or a thermosetting material, and in this case, the second uneven surface 1610 on the light diffusion structure 160 may be formed by a physical method such as mold stamping. In other embodiments, the light diffusion structure 160 is also a plastic film structure or a glass film structure, and in this case, the second concave-convex surface 1610 may be formed on the light diffusion structure 160 by a mold stamping or etching method. The adoption of the light diffusion structure 160 can reduce the difficulty of the manufacturing process and reduce the material cost, compared to the solution of generally coating acrylic particles to achieve the light diffusion effect. Preferably, the light diffusion structure 160 has a high transmittance.
In some embodiments, the light diffusion structure 160 includes a plurality of second protrusions 1611 arranged at intervals, and the plurality of second protrusions 1611 form a second concave-convex surface 1610 of the light diffusion structure 160. The width of the cross section of the second protrusion 1611 is gradually decreased in the direction from the cover plate 120 to the display module 110, wherein the cross section is perpendicular to the light scattering structure 160. Specifically, in some embodiments, the second protrusion 1611 may be any one of a cone, a pyramid, a hemisphere, a semi-ellipsoid, and a rhomboid. In contrast, a recessed region will be formed between two adjacent second protrusions 1611. In some embodiments, the second rugged surface 1610 can be formed by stamping or etching to form a plurality of second protrusions 1611 on the light scattering structure 160. Preferably, the plurality of second protrusions 1611 are arranged in a regular array, and the regular arrangement can make the scattering effect of each region in the second concave-convex surface 1610 to be consistent, so as to avoid a large difference in the anti-glare effect between different regions.
The light irradiated onto the second uneven surface 1610 by the display module 110 is scattered (diffused) by the plurality of second protrusions 1611, passes through the light scattering structure 160, and then reaches the cover plate 120 and the anti-glare structure 121. Since the first protrusions 1211 on the first uneven surface 1210 form the micro lenses, when the second uneven surface 1610 scatters the light of the display module 110 so that the light cannot directly reach the first protrusions 1211, the phenomenon that the directly irradiated light is focused under the micro lenses to form snowflake-shaped flash points can be effectively prevented, and the display effect of the display device 10 is improved.
For example, when the light diffusion structure 160 is a structure formed by uv-curable adhesive, a semi-cured uv-curable adhesive layer may be formed first, then the uv-curable adhesive layer is imprinted by an imprint mold, so as to form a plurality of second protrusions 1611 on the uv-curable adhesive layer, and then the uv-curable adhesive layer is cured by uv light, so as to obtain the light diffusion structure 160. At this time, the second protrusions 1611 formed by embossing, etching, or the like have a controllable shape and size, and thus the roughness of the second uneven surface 1610 can be controlled.
In some embodiments, the roughness of the second bumpy surface 1610 is less than the roughness of the first bumpy surface 1210, i.e., the profile of the second bump 1611 is smoother than the profile of the first bump 1211. At this time. The second uneven surface 1610 with a lower roughness has a higher transmittance, and can prevent the light entering the light scattering structure 160 from the display module 110 from being scattered at an excessive angle (the image light is blurred when the scattering angle is too large), so as to ensure that the displayed image of the display device 10 has a good definition.
In addition, it should be noted that, since the second uneven surface 1610 has uneven characteristics, if the second uneven surface 1610 is directly connected to an adjacent device (such as a substrate, a touch module, a display module, etc.), the recessed area on the second uneven surface 1610 forms a gap, and the air in the gap diffuses light entering the light diffusion structure 160 through the gap at a large angle, so that the displayed image of the display device 10 is blurred, and the display quality is affected. In addition, the presence of the voids will make it easier for impurities such as dust in the display device 10 to enter the voids of the second uneven surface 1610, resulting in a problem that the display device 10 causes black spots or the like in an image at the time of display. Thus, in some embodiments, the second uneven surface 1610 is provided with the first adhesive layer 111 thereon, and the first adhesive layer 111 can cover the gap on the second uneven surface 1610 and function to connect the light dispersion structure 160 with an adjacent element. Preferably, the first bonding layer 111 fills the second bumpy surface 1610.
In some embodiments, the refractive index of the first adhesive layer 111 is smaller than that of the light diffusion structure 160. At this time, the light entering the light dispersion structure 160 through the first adhesive layer 111 has a good scattering effect, and the light is prevented from reaching the first concave-convex surface 1210 more intensively, thereby weakening the flash point phenomenon.
As shown in fig. 1, in some embodiments, the display device 10 further includes a substrate 150 disposed between the cover plate 120 and the display module 110, and the substrate 150 may be used to dispose the light scattering structure 160 or the touch electrode. In some embodiments, the substrate 150 may be a poly-terephthalic Plastic (PET) or a glass substrate.
In some embodiments, the display device 10 further includes a second adhesive layer 112, the second adhesive layer 112 is disposed between the anti-glare structure 121 and the display module 110, and the second adhesive layer 112 can be used to connect two adjacent components of the display device 10, such as the cover plate 120 and the light scattering structure 160, the cover plate 120 and the substrate 150, the substrate 150 and the light scattering structure 160, and the like. In some embodiments, the second adhesive layer 112 may be made of an optical adhesive or a photoresist, such as a uv curable adhesive, a uv curable resin, an infrared curable adhesive, or a thermosetting material. Preferably, the second adhesive layer 112 uniformly covers the connecting surfaces of two adjacent connecting elements, and prevents air bubbles from occurring on the connecting surfaces.
The arrangement of the elements of the display device 10 will now be described with reference to an embodiment: the display device 10 includes a display module 110, a cover plate 120 and a substrate 150 disposed between the cover plate 120 and the display module 110, wherein a first connecting surface 1220 of the anti-glare structure 121 connects a surface of the cover plate 120 away from the display module 110, a second bonding layer 112 is disposed between the cover plate 120 and the substrate 150 to achieve connection, a second connecting surface 1620 of the light-scattering structure 160 connects a surface of the substrate 150 close to the display module 110, a first bonding layer 111 is disposed on a second concave-convex surface 1610 of the light-scattering structure 160, and the first bonding layer 111 fills and levels the second concave-convex surface 1610 and connects the light-scattering structure 160 and the display module 110.
In some embodiments, the display device 10 further includes a touch module 130. The touch module 130 includes a first touch electrode 131 and a second touch electrode 132, which are disposed in an insulating manner, and the first touch electrode 131 and the second touch electrode 132 are used for determining touch coordinates.
