As shown in fig. 4, the light incident side of the display module 110 refers to the side of the display module 110 facing the external environment, and the external ambient light can enter from the light incident side of the display module 110.
Further, one side that deviates from display module assembly 110 at anti-dazzle layer 120 still sets up diamond-like carbon layer 130, and diamond-like carbon layer 130 can further promote anti-dazzle layer 120 and display module assembly 110's resistant scratch performance, forms better protection to anti-dazzle layer 120 and display module assembly 110, promotes the surface hardness and the antifriction performance of flexible display screen 100. Specifically, the diamond-like carbon layer 130 is a metastable non-static substance containing a diamond structure (SP3 hybrid bond) and a graphite structure (SP2 hybrid bond), and carbon atoms are mainly acted by SP3 hybrid bond and SP2 hybrid bond and are prepared on the antiglare layer 120 by adopting a physical vapor deposition or chemical vapor deposition process.

It should be noted that the display module 110 includes an ultra-thin glass 111, a polarizer 112, and a display panel 113 stacked in sequence along the incident direction of the external light, and the anti-glare layer 120 is disposed on the light incident side of the ultra-thin glass 111. It should be noted that the ultra-thin glass 111 and the antiglare layer 120, the ultra-thin glass 111 and the polarizer 112, and the polarizer 112 and the display panel 113 are all connected by the optical cement 114, and the optical cement 114 does not affect the propagation of light due to its light transmittance under the premise of adhesion.
Optionally, the display module 110 includes a liquid crystal display module 110 or an organic light emitting diode display module 110, the liquid crystal display module 110 is a passive light emitting device, and does not have a display function, and a backlight source needs to be disposed to provide illumination light for the liquid crystal display module 110, so as to complete the display function together with the liquid crystal display module 110. The oled display module 110 is an active light emitting device, and does not need a backlight source to provide illumination light for the oled display module 110, so that the thickness of the oled display module 110 is smaller than that of the lcd display module 110, and the size of the flexible display screen 100 is reduced. The organic light emitting diode display module 110 has the advantages of good display effect, strong layering sense and high color reduction degree, and the display effect of the flexible display screen 100 is improved.
The display module 110 in the flexible display screen 100 according to the embodiment of the present application is well known to those skilled in the art, and will not be described in detail herein.
According to an embodiment of the present application, as shown in fig. 1, the antiglare layer 120 includes an organic film layer 121 and light-transmitting particles 122, and the light-transmitting particles 122 are disposed on the organic film layer 121, including but not limited to, in or on the organic film layer, so that the organic film layer 121 forms a scattering surface.
In this embodiment, the antiglare layer 120 includes an organic film layer 121 and light-transmitting particles 122, and the organic film layer 121 includes at least one of: transparent polyimide, transparent thermoplastic polyester (such as polyethylene terephthalate, abbreviated as PET). The light-transmitting particles 122 are disposed in the organic film layer 121, that is, the light-transmitting particles 122 and the organic film layer 121 form an integral film layer, so as to achieve an anti-glare effect and simplify the preparation process. Since the organic film 121 has light transmittance and the light-transmitting particles 122 also have light transmittance, the light transmission is not affected. The transparent particles 122 can be disposed inside the organic film 121, and can also protrude from the surface of the organic film 121 away from the display module 110. The transparent particles 122 and the organic film layer 121 cooperate to form a scattering surface facing the diamond-like carbon layer 130, and the distance between the scattering surface and the diamond-like carbon is not completely equal, that is, the scattering surface is in an uneven state, and when external ambient light irradiates the uneven scattering surface, the light can be well scattered by the scattering surface, so that the anti-glare layer 120 has an anti-glare function.
The light-transmitting particles 122 are transparent particles or translucent particles.
Further, the light-transmitting particles 122 have different reflectivity from the organic film 121.
In this embodiment, since the light-transmitting particles 122 and the organic film layer 121 have different reflectivities, when external light is emitted to the light-transmitting particles 122 or the organic film layer 121, the light-transmitting particles 122 and the organic film layer 121 can reflect the light at different angles, and at this time, the scattering effect of the anti-glare layer 120 is significantly improved as a whole.
Further, the light transmissive particles 122 include polysiloxane microspheres.
In this embodiment, the light-transmitting particles 122 include polysiloxane microspheres, which refer to polymer microspheres with polysiloxane as a base material. Has the characteristics of large specific surface area, low relative density, heat resistance, weather resistance, no toxicity, no odor, good lubricating property, good hydrophobicity and the like. Furthermore, the diameter of the polysiloxane microspheres is more than or equal to 10 μm and less than or equal to 50 μm.
According to still another embodiment of the present application, as shown in fig. 2, the antiglare layer 120 includes an organic film layer 121 and an anti-glare layer 123, the anti-glare layer 123 is disposed on a side of the organic film layer 121 close to the diamond-like carbon layer 130, and the anti-glare layer 123 has a scattering surface.
In this embodiment, the organic film 121 includes at least one of the following: transparent polyimide, transparent thermoplastic polyester (such as polyethylene terephthalate, abbreviated as PET). The anti-glare layer 123 is disposed on a side of the organic film layer 121 close to the diamond-like carbon layer 130, that is, the anti-glare layer 123 may be sandwiched between the diamond-like carbon layer 130 and the organic film layer 121. The anti-glare layer 123 and the organic film layer 121 may be separately prepared as relatively independent film layers, and different anti-glare effects may be achieved by controlling characteristics of the anti-glare layer 123. The anti-glare layer 123 has a scattering surface facing the diamond-like carbon layer 130, and the distance between the scattering surface and the diamond-like carbon layer 130 is not completely equal, that is, the scattering surface is in an uneven state, and when external environment light irradiates the uneven scattering surface, the light can be well scattered by the scattering surface, so that the anti-glare layer 120 has an anti-glare function. The anti-glare layer 120 can effectively scatter external ambient light and effectively reduce the glare effect of ambient strong light, for example, the phenomenon of light reflection cannot be seen when the anti-glare layer is used indoors.
The anti-glare layer 123 has light scattering particles therein, and the light scattering particles have a high elastic state, so that the crease resistance and the scratch resistance of the anti-glare layer 123 can be improved.
Further, the anti-glare layer 123 includes silica sol, resin.
In this embodiment, the preparation of the silica sol refers to spraying the silica sol particles on the organic film layer 121 to form a rough scattering surface. Alternatively, the resin itself has a rugged scattering surface.
According to some embodiments of the present application, the antiglare layer 120 includes scattering protrusions 124 protruding in a direction away from the display module 110, and the roughness of the scattering surface is 0.1 μm or more and 0.5 μm or less.
Further, the haze of the antiglare layer 120 is 10% or more and 80% or less;
further, the anti-glare layer 120 has a transmittance of 70% or more.
In this embodiment, whether the anti-glare layer 120 is formed by the light-transmitting particles 122 and the organic film layer 121, or by the organic film layer 121 and the anti-glare layer 123 which are stacked independently, in both embodiments, the anti-glare layer 120 includes the scattering protrusions 124 protruding in a direction away from the display module 110, and the distances between the heat dissipation surface and the diamond-like carbon layer 130 are not exactly the same due to the heat dissipation protrusions. Specifically, the roughness of the scattering surface is 0.1 μm or more and 0.5 μm or less, and the roughness generally means surface roughness. The surface roughness refers to the unevenness of the surface having small pitches and minute peaks and valleys. The distance between two wave crests or two wave troughs (wave distance) is very small (below 1 mm), and the micro geometrical shape error belongs to. When the roughness of the scattering surface satisfies the above range, an effective diffuse reflection effect of the antiglare layer 120 can be ensured. Further, the haze of the antiglare layer 120, which is the percentage of the transmitted light intensity at an angle of 2.5 ° or more from the incident light to the total transmitted light intensity, satisfies the above range, and a larger haze means a decrease in the film gloss and transparency, particularly, the degree of image formation.
