The box base 20 is divided into two cavities by the partition plate 23. The first cavity 211 is proximal to the box cover 10 and is an unsealed cavity, and one end of the first cavity 211 towards the box cover 10 is provided with an opening, such that it is convenient to store the article in the first cavity 211 or take the article out of the first cavity 211.

In the embodiments of the present disclosure, the first cavity 211 may be configured to accommodate a cosmetic product, such as a pressed powder 60.

The second cavity 212 formed by dividing the box base 20 by the partition plate 23 is a closed cavity and is configured to store electronic devices such as the circuit board 41, such that the electronic devices such as the circuit board 41 are effectively isolated from the external environment, thereby protecting the electronic devices in the display device.

Optionally, as shown in FIGS. 5 and 6, the display device further includes a power supply 42. The power supply 42 is electrically connected to the circuit board 41 and is disposed in the second cavity 212.

Exemplarily, the power source 42 may be a battery, for example, a lithium battery, a lead battery and another battery having a charging function, and a disposable battery such as a button battery.

As shown in FIGS. 5 and 6, the box base 20 further includes a heat-insulting plate 24. The heat-insulting plate 24 is disposed in the second cavity 212 and disposed between the circuit board 41 and the power supply 42.

By providing the plurality of supporting columns 25 on the bottom surface of the box base 20 as supporting foundations of the partition plate 23, the partition plate 23 can be disposed in the middle of the accommodating cavity 210, so as to divide the accommodating cavity 210 into two cavities.

As the partition plate 23 is provided on the end faces of the supporting columns 25, the height of the supporting columns 25 is the height of the second cavity 212. In the embodiments of the present disclosure, a ratio of the first cavity 211 to the second cavity 212 may be changed by adjusting the height of the supporting columns 25.

Exemplarily, as shown in FIGS. 5 and 6, four supporting columns 25 distributed at intervals are provided in the second cavity 212.

As shown in FIG. 6, the end face of each supporting column 25 is provided with a screw hole 251, and first through holes 231 are formed in a region of the partition plate 23 corresponding to the supporting columns 25. After the partition plate 23 is placed on the supporting columns 25, the screw holes 251 directly face the corresponding first through holes 231, such that bolts can pass through the first through holes 231 to be screwed with the screw holes 251, thereby fixing the partition plate 23 on the supporting columns 25.

Optionally, as shown in FIG. 5, each first through hole 231 in the partition plate 23 is a counterbore, such that after the bolt is screwed into the screw hole 251, a head of the bolt can be disposed in the counterbore, so as to prevent the head of the bolt from protruding from the partition plate 23 and affecting the placement of the article.

The cushion block 27 may be a rubber block, and can provide a frictional force between the box base 20 and the platform, such that after being placed on the platform, the box base 20 is prevented from easily sliding.

FIG. 7 is an exploded view of a box cover according to some embodiments of the present disclosure. As shown in FIG. 7, a surface of the box cover 10 facing the box base 20 is provided with an embedding groove 11, and the mirror display panel 30 is disposed in the embedding groove 11.

By forming the embedding groove 11 for accommodating the mirror display panel 30 on the surface of the box cover 10, the mirror display panel 30 may be prevented from protruding from the surface of the box cover 10, thereby protecting the mirror display panel 30. Meanwhile, the purpose of integrated design of the box cover 10 and the mirror display panel 30 is achieved.

Optionally, as shown in FIG. 7, the mirror display panel 30 includes a panel body 31 and a driving integrated circuit 32, and the panel body 31 is electrically connected to the driving integrated circuit 32.

The driving integrated circuit is connected to the panel body, and is configured to control each pixel unit in the panel body to be electrified and to emit light, so as to drive the panel body to display the image. In the embodiments of the present disclosure, the driving integrated circuit may drive the panel body to display the image under the control of the circuit board.

FIG. 8 is a schematic layered diagram of a panel body according to some embodiments of the present disclosure. As shown in FIG. 8, the panel body 31 includes a display substrate 310 and a metal reflecting layer 311 which are sequentially stacked.

As shown in FIG. 8, the display substrate 310 includes a base substrate 312 and a plurality of light-emitting units 313, and the plurality of light-emitting units 313 are arranged on the base substrate 312 in an array.

As shown in FIG. 8, the metal reflecting layer 311 is provided with a plurality of light-transmitting holes 314, and each of the light-transmitting holes 314 corresponds to at least one of the light-emitting units 313.

An orthogonal projection of the light-transmitting hole 314 on the base substrate 312 at least partially coincides with an orthogonal projection of the light-emitting unit corresponding to the light-transmitting hole 314 on the base substrate 312.

Optionally, the light-transmitting holes 314 may be in one-to-one correspondence with the light-emitting units, or the light-transmitting hole 314 may also correspond to the plurality of light-emitting units simultaneously, which is not limited in the embodiments of the present disclosure.

In the embodiments of the present disclosure, by forming the light-transmitting holes 314 corresponding to the light-emitting units, the light emitted by the light-emitting units can pass through the metal reflecting layer to achieve the function of displaying the image by the panel body. In addition, the metal reflecting layer may be configured to reflect external ambient light, such that the panel body can be used as a mirror.

Exemplarily, the metal reflecting layer includes an aluminum metal layer or a molybdenum metal layer.

Optionally, as shown in FIG. 8, the panel body 31 further includes a selective reflective layer 315. The selective reflective layer 315 is disposed on a surface of the metal reflecting layer 311 distal from the display substrate 310 and partially disposed in the light-transmitting holes 314. The selective reflective layer 315 includes a composite film layer composed of at least two materials which have different refractive indexes.

The refractive indexes of the at least two different materials in the selective reflective layer are different, such that the composite film layer composed of the at least two materials can select different wavelengths of light entering the composite film layer, thereby enabling the selective reflective layer to reflect light of a set color.

Exemplarily, the selective reflective layer includes a SiN_x/SiO₂/SiN_x composite film layer.

Optionally, as shown in FIG. 8, the panel body 31 further includes an atomizing layer 316. The atomizing layer 316 is disposed on a surface of the metal reflecting layer 311 distal from the display substrate 310.

By providing the atomizing layer on the display substrate, a screen brightness of the panel body can be reduced, such that the screen brightness is relatively soft, the color is brighter, and an obvious matte effect is achieved.

Exemplarily, the atomizing layer may include an adhesive material and scattering particles; and the scattering particles are dispersed in the adhesive material, or are coated on a side of the adhesive material distal from the base substrate.

An adhesive material monomer is doped with particles having a scattering function, such that part of the light can be scattered, thereby achieving an atomizing effect.

Exemplarily, the adhesive material is a triacetate fiber material; and the scattering particles are made of an acrylic material or silicon dioxide.

Exemplarily, the scattering particles are spherical, and the diameters of the scattering particles are 2 μm to 9 μm.

Exemplarily, the atomizing layer contains at least two types of scattering particles having different diameters.

The scattering particles made of the acrylic or silicon dioxide material are dispersed into the adhesive material monomer to form an optical film layer, such that micron-level concave-convex surfaces can be formed in the optical film layer. These concave-convex surfaces can refract incident light and play the role of light diffusion. In addition, as the function of the spherical scattering particle is similar to that of a convex lens, in the case that light passes through these particles, the light is focused to an exit angle. Thus, a function of ensuring the brightness can be achieved. Moreover, the scattering particles with different sizes also ensure that light cannot be directly emitted from the diffusing film, thereby further playing the role of atomization. In addition, a haze may be controlled by controlling the concentration of the scattering particles. The more scattering particles are, the more dispersed the scattered light is, and the greater the haze is.

Optionally, the haze of the atomizing layer is 20% to 30%. By setting the haze of the atomizing layer within the above range, it avoids the adverse influence on a clarity of the display effect caused by an increased diffuse reflectance arising from a too large haze, and moreover, it avoids a reduced matte feeling of the panel body caused by an insufficient diffuse reflectance extent arising from a too small haze of the atomizing layer.

The haze refers to a cloudy or turbid appearance in the interior or on the surface of a transparent or semi-transparent material caused by light diffusion, and is expressed as a percentage of a ratio of a flux of diffused light to a flux of light passing through the material. Specifically, in the case that a beam of parallel light from a standard “c” light source is vertically incident on a transparent or semi-transparent film, sheet and plate, some parallel light deviates from the incident direction due to scattering inside and on the surface of the material; and the haze, that is, the percentage of the ratio of the flux Td of scattered light which deviates from the incident direction by more than 2.5 degrees to the flux T2 of the light passing through the material, is an important parameter of optical transparency of the transparent or semi-transparent material.

Exemplarily, the haze of the atomizing layer is 25%.

The thickness of the mounting table 12 is not greater than the depth of the embedding groove 11, and a difference between the thickness of the mounting table 12 and the depth of the embedding groove 11 may be not less than the thickness of the panel body 31, such that the mirror display panel 30 is prevented from protruding from the surface of the box cover 10 after the panel body 31 is mounted on the mounting table 12, thereby protecting the mirror display panel 30.

In addition, the thickness of the mounting table 12 is not less than that of the driving integrated circuit 32.
