[0055] Figure 1 is a structural schematic diagram of a display device provided by an embodiment of the disclosure. As shown in Figure 1 the display device includes a box cover 10, a box base 20, and a mirror display panel 30. The box cover 10 is connected to the box base 20, and the mirror display panel 30 is connected to the box cover 10.

[0056] In an embodiment of the disclosure, the box cover 10 is configured to have an open state and a closed state. Figure 1 The illustrated box cover 10 is in the open state. As shown in Figure 1 when the box cover 10 is in the open state, the box cover 10 is at least partially separated from the box base 20, and the mirror display panel 30 is located outside the box base 20.

[0057] Figure 2 is a structural schematic diagram of another display device provided by an embodiment of the disclosure. Figure 2 The illustrated box cover 10 is in the closed state. As shown in Figure 2 when the box cover 10 is in the closed state, the mirror display panel 30 is located inside the box base 20.

[0058] This disclosure provides a display device including a cover 10, a base 20, and a mirrored display panel 30. The cover 10 is connected to the base 20, and the mirrored display panel 30 is disposed on the cover 10. After assembly, the cover 10 and base 20 have two states: the mirrored display panel 30 can be installed inside the base 20 or moved outside the base 20. By providing these two states, the user's need to expose the mirrored display panel 30 can be met, while the mirrored display panel 30 can be hidden within the base 20, thus protecting it.

[0059] Furthermore, by combining the mirror display panel 30 with the box lid 10, the mirror display panel 30 is installed on the box. Since this combination method effectively reduces the size of the mirror display panel 30, it is convenient for users to carry.

[0060] Figure 3 This is an exploded view of a display device provided in an embodiment of this disclosure. Figure 3 As shown, the display device also includes: a circuit board 41 and an adapter cable 43. The housing base 20 has a receiving cavity 210, the circuit board 41 is located in the receiving cavity 210, and the circuit board 41 and the mirror display panel 30 are connected by the adapter cable 43.

[0061] This separates the electronic components used to connect to the mirror display panel 30 from the mirror display panel 30, allowing each electronic component to be installed separately in the base 20 or the cover 10. This makes full use of the internal space of the base 20 and the cover 10, so that each electronic component in the display device can be reasonably installed in the base 20 and the cover 10.

[0062] Furthermore, the circuit board 41 is housed inside the housing base 20, while a portion of the adapter cable 43 is within the housing base 20, and the other portion is inside the housing cover 10. This design prevents the circuit board 41 from being exposed and also conceals most of the adapter cable 43, thereby improving reliability.

[0063] For example, the circuit board 41 can be a printed circuit board (PCB) or a flexible printed circuit board (FPCB). The circuit board 41 is connected to the mirror display panel 30, and the circuit board 41 can control the mirror display panel 30 to display an image so that the mirror display panel 30 has a display function.

[0064] Figure 4 This is a schematic diagram of the structure of a box base 20 provided in an embodiment of this disclosure. For example... Figure 4As shown, the box base 20 has a connecting hole 22, one end of which is located on the cavity wall of the receiving cavity 210, and the other end of which is located at the connection between the box cover 10 and the box base 20; a part of the adapter cable 43 is located in the connecting hole 22, and the other part of the adapter cable 43 is located inside the box cover 10.

[0065] By providing a connecting hole 22 at the location where the box base 20 connects to the box cover 10, the adapter cable 43 extending from the box cover 10 can be directly inserted into the connecting hole 22 to connect with the circuit board 41 inside the box base 20, so as to minimize the exposure of the adapter cable 43 to the external environment and protect the adapter cable 43.

[0066] Figure 5 This is an exploded view of a box base provided in an embodiment of this disclosure. For example... Figure 5 As shown, the box base 20 also includes a partition 23.

[0067] Figure 6 yes Figure 1 An AA cross-sectional view is provided. For example... Figure 6 As shown, partition 23 divides the receiving cavity 210 into a first cavity 211 and a second cavity 212. Combined with... Figure 5 , 6 The first cavity 211 is close to the lid 10 and is used to hold items. The circuit board 41 and the power supply 42 are located in the second cavity 212.

[0068] The box base 20 is divided into two cavities by the partition 23. The first cavity 211 is close to the box cover 10 and is not closed. The end of the first cavity 211 facing the box cover 10 has an opening, which facilitates the storage or retrieval of items contained in the first cavity 211.

[0069] In this embodiment of the disclosure, the first cavity 211 can be used to contain cosmetic products, such as powder compact 60, etc.

[0070] The second cavity 212, which is divided by the base 20 and the partition 23, is a closed cavity. The second cavity 212 is used to store electronic components such as the circuit board 41, so as to effectively isolate the electronic components such as the circuit board 41 from the external environment and protect the electronic components in the display device.

[0071] Optionally, such as Figure 5 , 6 As shown, the display device also includes a power supply 42, which is electrically connected to the circuit board 41 and is located inside the second cavity 212.

[0072] For example, the power source 42 can be a battery. For example, a rechargeable battery such as a lithium battery or a lead-acid battery, or a disposable battery such as a button cell battery.

[0073] As shown in Figure 5 , 6 , the box base 20 further comprises a heat insulation plate 24, the heat insulation plate 24 is located in the second cavity 212, and the heat insulation plate 24 is located between the circuit board 41 and the power supply 42, the heat insulation plate 24 has a connecting groove 241 penetrating through the heat insulation plate 24, and the circuit board 41 and the power supply 42 are electrically connected through the connecting groove 241.

[0074] Since the power supply 42 is easy to heat during the power supply process of the mirror display panel 30, in order to avoid the damage of the circuit board 41 placed together with the power supply 42 due to the heat of the power supply 42, the heat insulation plate 24 is arranged in the second cavity 212, and the power supply 42 and the circuit board 41 are separated by the heat insulation plate 24, so as to effectively reduce the heat transferred from the power supply 42 to the circuit board 41, and prevent the damage of the circuit board 41.

[0075] Meanwhile, in order to avoid affecting the electrical connection between the circuit board 41 and the power supply 42 due to the arrangement of the heat insulation plate 24, the connecting groove 241 is arranged on the heat insulation plate 24, the connecting groove 241 penetrates through the heat insulation plate 24, so that the power supply 42 can be electrically connected with the circuit board 41 on the other side of the heat insulation plate 24 through the connecting groove 241.

[0076] Exemplarily, the heat insulation plate 24 is a structure piece made of asbestos. The asbestos has good heat insulation effect, which can effectively reduce the heat transferred from the side of the power supply 42 on the heat insulation plate 24 to the side of the circuit board 41 on the heat insulation plate 24, and prevent the damage of the circuit board 41.

[0077] Optionally, as shown in Figure 5 , 6 , the second cavity 212 has a plurality of support columns 25 distributed at intervals, the partition plate 23 is located at the end face of the plurality of support columns 25, and the partition plate 23 is detachably connected with the plurality of support columns 25.

[0078] The plurality of support columns 25 are arranged on the bottom surface of the box base 20 to serve as the support basis of the partition plate 23, so that the partition plate 23 can be located at the middle position of the containing cavity 210 to divide the containing cavity 210 into two cavities.

[0079] Since the partition plate 23 is arranged at the end face of the support column 25, the height of the support column 25 is the height of the second cavity 212. In the embodiment of the present disclosure, the height of the support column 25 can be adjusted to change the proportion of the first cavity 211 and the second cavity 212.

[0080] Exemplarily, as shown in Figure 5 , four support columns 25 are arranged in the second cavity 212.

[0081] As shown in Figure 5As shown, the end surface of the support column 25 has a threaded hole 251, and the region of the partition plate 23 corresponding to the support column 25 is provided with a first through hole 231. After the partition plate 23 is placed on the support column 25, the threaded hole 251 is opposite to the corresponding first through hole 231, so that a bolt can be screwed through the first through hole 231 and the threaded hole 251 to be threadedly connected, so as to fix the partition plate 23 on the support column 25.

[0082] Optionally, as shown in Figure 6 , the first through hole 231 on the partition plate 23 is a counterbore, so that the head of the bolt can be located in the counterbore after the bolt is screwed into the threaded hole 251, so as to avoid the head of the bolt protruding from the partition plate 23 and affecting the placement of the article.

[0083] As shown in Figure 5 , 6 , in order to avoid the heat insulation plate 24 blocking the support column 25, a second through hole 242 can be provided on the heat insulation plate 24, the second through hole 242 is for the support column 25 to pass through, so that the end surface of the support column 25 abuts against the partition plate 23.

[0084] Optionally, as shown in Figure 4 , the bottom of the box base 20 can be provided with a limiting groove 26, the shape and size of the limiting groove 26 are consistent with the shape and size of the power supply 42, so that the power supply 42 can be accommodated in the limiting groove 26, preventing the power supply 42 from loosening.

[0085] As shown in Figure 5 , 6 , the surface of the box base 20 away from the box cover 10 is provided with a pad 27. The pad 27 can prevent the box base 20 from directly contacting the platform and being worn, so as to protect the box base 20.

[0086] Among them, the pad 27 can be a rubber block, which can provide friction between the box base 20 and the platform, preventing the box base 20 from easily sliding on the platform.

[0087] Figure 7 is a disassembly view of the box cover 10 provided by the embodiment of the present disclosure. As shown in Figure 7 , the surface of the box cover 10 opposite to the box base 20 has an embedded groove 11, and the mirror display panel 30 is located in the embedded groove 11.

[0088] By providing the embedded groove 11 on the surface of the box cover 10 for accommodating the mirror display panel 30, the mirror display panel 30 can not protrude from the surface of the box cover 10, so as to protect the mirror display panel 30. At the same time, the purpose of integrating the box cover 10 and the mirror display panel 30 is achieved.

[0089] Optionally, as shown in Figure 7As shown, the mirror display panel 30 includes a panel body 31 and a driving integrated circuit 32, and the panel body 31 is electrically connected with the driving integrated circuit 32.

[0090] The panel body 31 is a part of the mirror display panel for displaying images, and the panel body can be an OLED (Organic Light-Emitting Diode) display panel. The driving integrated circuit is connected with the panel body, and is used for controlling each pixel unit in the panel body to be powered to emit light, so as to drive the panel body to display images. In the embodiment of the present disclosure, the driving integrated circuit can drive the panel body to display images under the control of the circuit board.

[0091] Figure 8 is a hierarchical schematic diagram of the panel body provided by the embodiment of the present disclosure. As Figure 8 shown, the panel body 31 includes a display substrate 310 and a metal reflection layer 311 which are stacked in sequence.

[0092] As Figure 8 shown, the display substrate 310 includes a substrate 312 and a plurality of light emitting units 313, and the plurality of light emitting units 313 are arranged in an array on the substrate 312.

[0093] As Figure 8 shown, the metal reflection layer 311 has a plurality of light transmission holes 314, and each light transmission hole 314 is opposite to at least one light emitting unit 313.

[0094] The orthogonal projection of the light transmission hole 314 on the substrate 312 at least partially overlaps with the orthogonal projection of the corresponding light emitting unit on the substrate 312.

[0095] Optionally, the light transmission hole 314 can be opposite to one light emitting unit, or the light transmission hole 314 can be opposite to a plurality of light emitting units at the same time, and the embodiment of the present disclosure does not make any limitation.

[0096] In the embodiment of the present disclosure, by arranging the light transmission hole 314 opposite to the light emitting unit, the light emitted by the light emitting unit can be transmitted through the metal reflection layer to achieve the effect of displaying images by the panel body; and the metal reflection layer can be used to reflect external ambient light, so that the panel body can be used as a mirror.

[0097] Exemplarily, the metal reflection layer includes an aluminum metal layer or a molybdenum metal layer.

[0098] Optionally, as Figure 8 shown, the panel body 31 further includes a selective reflection layer 315, the selective reflection layer 315 is located on the surface of the metal reflection layer 311 away from the display substrate 310, and part of the selective reflection layer 315 is located in the light transmission hole 314, and the selective reflection layer 315 includes a composite film layer composed of at least two materials, and the refractive indexes of the at least two materials are different.

[0099] The refractive indexes of the at least two different materials in the selective reflection layer are different, so that the composite film layer composed of the at least two materials can select light of different wavelengths entering the composite film layer, and thus the selective reflection layer reflects light of a set color.

[0100] For example, the selective reflection layer can include SiN x / SiO2 / SiN x The composite film layer.

[0101] Optionally, as Figure 8 As shown, the panel body 31 further includes a haze layer 316 located on the surface of the metal reflection layer 311 away from the display substrate 310.

[0102] By arranging the haze layer on the display substrate, the screen brightness of the panel body can be reduced, the screen brightness is soft, the color is bright, and the screen has a clear matte effect.

[0103] For example, the haze layer can include a glue material and scattering particles; the scattering particles are dispersed in the glue material, or the scattering particles are coated on the side of the glue material away from the substrate.

[0104] The glue material monomer is doped with scattering functional particles, which can scatter part of the light to achieve the haze effect.

[0105] For example, the glue material is a triacetate fiber material; and the scattering particles are acrylic materials or silicon dioxide.

[0106] For example, the scattering particles are spherical, and the diameter of the scattering particles is 2-9 μm.

[0107] For example, the haze layer contains at least two scattering particles with different diameters.

[0108] The scattering particles made of acrylic or silicon dioxide materials are dispersed into the glue material monomer to form an optical film layer, which can form micron-level concave-convex surfaces in the optical film layer. These concave-convex surfaces can cause the incident light to be dispersed, and play a role of light diffusion. In addition, the scattering particles are spherical, and their function is similar to that of convex lenses. When the light passes through these particles, it is focused to a certain exit angle, thereby ensuring the brightness. In addition, the scattering particles with different particle sizes also ensure that the light will not be directly emitted from the diffusion film, thereby further achieving the haze effect. In addition, the haze can be controlled by controlling the concentration of the scattering particles. The more the scattering particles, the more the scattered light is dispersed, and the greater the haze.

[0109] Optionally, the haze of the haze layer is 20% to 30%. By setting the haze of the haze layer in the above range, the haze degree can be prevented from being too large, the diffuse reflectivity is increased, the display effect is affected, and the haze degree of the haze layer can be prevented from being too small, the amplitude of the diffuse reflectivity is not enough, and the metal matte feeling of the panel body is reduced.

[0110] The haze refers to the cloud-like or turbid appearance of the inside or surface of a transparent or translucent material due to light diffusion. The haze is expressed as the percentage of the ratio of the diffuse light flux to the light flux transmitted through the material. Specifically, a beam of parallel light of a standard "c" light source is vertically irradiated onto a transparent or translucent film, sheet or plate. Due to the scattering of the inside and surface of the material, part of the parallel light deviates from the incident direction. The haze is the percentage of the ratio of the scattered light flux Td deviating from the incident direction greater than 2.5° to the light flux T2 transmitted through the material. The haze is an important parameter of the optical transparency of the transparent or translucent material.

[0111] For example, the haze of the haze layer is 25%.

[0112] As shown in Figure 7 , the embedding groove 11 has a mounting table 12. A part of the panel body 31 is located on the mounting table 12. Another part of the panel body 31, the mounting table 12 and the groove bottom of the embedding groove 11 form a mounting cavity 13. The driving integrated circuit 32 is located in the mounting cavity 13.

[0124] The first lug 111 is arranged on the box cover 10, and the second lug 112 is arranged on the box base 20. When the box cover 10 is connected with the box base 20, the first lug 111 and the second lug 112 are aligned in parallel, and the first hinge hole 113 of the first lug 111 and the second hinge hole 114 of the second lug 112 are coaxial, so that the pin shaft 115 can pass through the first hinge hole 113 and the second hinge hole 114 at the same time. Thus, the box cover 10 can rotate around the pin shaft 115 relative to the box base 20 with the pin shaft 115 as the center axis, so as to realize the hinge connection of the box cover 10 and the box base 20.

[0125] Exemplarily, as shown in Figure 9 , the box cover 10 has two first lugs 111, and the box base 20 is provided with corresponding two second lugs 112. The hinge connection of the box cover 10 and the box base 20 is realized by arranging multiple first lugs 111 and multiple second lugs 112, which can improve the hinge connection reliability of the box cover 10 and the box base 20.

[0126] Optionally, the display device further comprises a locking member, which is arranged on the box base 20 and is used for locking the relative angle of the box cover 10 and the box base 20.

[0127] The relative angle of the box cover 10 and the box base 20 is fixed by arranging the locking member, so that the box cover 10 and the box base 20 can maintain the angle required by the user, and the user can support the box cover 10 and the box base 20 with hands, which is convenient for the user to use.

[0128] Figure 10 is a schematic view of the assembly of the box cover 10 and the box base 20 provided by the embodiment of the present disclosure.

[0132] Wherein, the part of the ball 53 with a size smaller than the opening diameter of the opening section is located outside the barrel 51, when an external force presses the ball 53, the ball 53 is extruded to recover into the barrel 51 under the spring 52, when the external force disappears, the ball 53 returns to the open end under the elastic force of the spring 52.

[0133] In the embodiments of the present disclosure, in combination with Figure 9 , 10 , the arc surface on the first ear plate 111 is a circular arc surface, and the circular arc surface is provided with two locking grooves 116, since the ball 53 of the wave ball screw 50 is abutted on the arc surface, the ball 53 is recovered into the barrel 51 under the extrusion of the arc surface. During the rotation of the first ear plate 111, when the locking groove 116 on the arc surface is opposite to the ball 53, the external force applied by the arc surface to the ball 53 is released instantaneously, the ball 53 returns to the open end under the elastic force of the spring 52, and the part of the ball 53 with a smaller size enters into the locking groove 116, thereby limiting the continuous rotation of the first ear plate 111, and fixing the positions of the box cover 10 and the box base 20 relative to each other.

[0134] As shown in Figure 9 , 10 , the arc surface of the first ear plate 111 is provided with two locking grooves 116, one of the two locking grooves 116 is used for locking the first ear plate 111 when the box cover 10 is in an open state, and the other locking groove 116 is used for locking the first ear plate 111 when the box cover 10 is in a closed state.

[0135] Exemplarily, the interval distribution angle of the two locking grooves 116 is 90°, so that after the box cover 10 is opened, the box cover 10 and the box base 20 are just in a vertical state, which is convenient for the user to use.

[0136] It should be noted that the interval distribution angle of the two locking grooves 116 can be any other angle, and the specific angle to be adopted can be determined according to the user's use demand, and the embodiments of the present disclosure are not limited.

[0137] As shown in Figure 9 , 10 , the locking member comprises two wave ball screws 50, and the two wave ball screws 50 are arranged, which can improve the reliability of the locking member in locking the relative angle between the box cover 10 and the box base 20.

[0138] The third through hole 28 is arranged on the box base 20 for mounting the wave bead screw 50. A part of the wave bead screw 50 is inserted into the third through hole 28, and another part of the wave bead screw 50 is located outside the third through hole 28, so that the ball 53 of the wave bead screw 50 can be elastically inserted into the locking groove 116 of the first ear plate 111.

[0139] In some other implementations, the locking member can be a bolt. When the box cover 10 is rotated to the appropriate position, the bolt can be simultaneously inserted into the first ear plate 111 and the second ear plate 112 to lock the first ear plate 111 and the second ear plate 112, thereby fixing the relative angle between the box cover 10 and the box base 20.

[0140] In some other implementations, the locking member can also be a bracket. When the box cover 10 is rotated to the appropriate position, the bracket can support the box cover 10 to maintain the relative angle between the box cover 10 and the box base 20.

[0141] For example, the bracket can be a support plate located away from the surface of the box cover 10 facing the box base 20. One side of the support plate is connected to the box cover 10, and the other side of the support plate can abut against a platform on which the box base 20 is placed when the box cover 10 is opened, thereby maintaining the relative angle between the box cover 10 and the box base 20.

[0142] Optionally, as shown in Figure 1 the display device further comprises a first locking structure 17 and a second locking structure 18. The first locking structure 17 is located on the surface of the box cover 10 opposite to the box base 20, and the second locking structure 18 is located on the surface of the box base 20 opposite to the box cover 10. When the box cover 10 is in the closed state, the first locking structure 17 and the second locking structure 18 are locked and connected.

[0143] When the box cover 10 is in the closed state, the first locking structure 17 and the second locking structure 18 can be locked and connected, thereby maintaining the box cover 10 and the box base 20 in the closed state, avoiding the box cover 10 from being easily opened and the items in the box base 20 from being lost.

[0144] Exemplarily, as shown in Figure 1 the first locking structure 17 and the second locking structure 18 are both magnetic members.

[0145] In some other implementations, the first locking structure 17 and the second locking structure 18 are both magnets. The surface of the box cover 10 opposite to the box base 20 has a round hole for mounting the first locking structure 17, and the surface of the box base 20 opposite to the box cover 10 has a round hole for mounting the second locking structure 18. When the box cover 10 is in the closed state, the first locking structure 17 and the second locking structure 18 are opposite to each other, so that the first locking structure 17 and the second locking structure 18 can be attracted together.

[0146] Exemplarily, one of the first locking structure 17 and the second locking structure 18 is a protrusion, and the other of the first locking structure 17 and the second locking structure 18 is a groove, and the protrusion is detachably connected with the groove.

[0147] For example, the first locking structure 17 is a protrusion, and the second locking structure 18 is a groove, and when the box cover 10 is in the closed state, the protrusion is just inserted into the groove, and the box cover 10 is prevented from being easily separated from the box base 20 by the plug-in cooperation of the protrusion and the groove, so that the box cover 10 and the box base 20 remain in the connected state.

[0148] In some other embodiments of the present disclosure, in addition to the hinged connection between the box cover 10 and the box base 20, the box cover 10 and the box base 20 can also be connected by a flexible member.

[0149] Exemplarily, the box cover 10 and the box base 20 are connected by a flexible connecting band, one part of the flexible connecting band is connected with the box cover 10, and the other part of the flexible connecting band is connected with the box base 20.

[0150] The flexible connecting band can be a band-shaped object with flexibility and bendability, for example, the flexible connecting band can be a rubber band or a plastic band.

[0158] The image acquisition unit is used to acquire portrait data of the user and send the data to the control unit. The image acquisition unit can accurately acquire facial information of the user through face recognition technology.

[0159] The control unit can control the mirror display panel 30 to display cosmetic information, so that the user can select a cosmetic product. Meanwhile, the control unit can also obtain the selected cosmetic product and determine the part of the face to which the selected cosmetic product is applied according to the type of the selected cosmetic product.

[0160] For example, the control unit can determine the selected cosmetic product according to touch information of the mirror display panel. The control unit has a pre-stored corresponding relationship between the type of the cosmetic product and the position. When the selected cosmetic product is a lipstick, the control unit can determine that the position corresponding to the lipstick is the mouth according to the corresponding relationship and the type of the cosmetic product after obtaining that the cosmetic product is a lipstick.

[0161] In addition, the control unit can also receive the portrait data acquired by the image acquisition unit and generate information including at least the coordinates and size of the specific position of the facial features, so as to determine the image overlay position according to the acquired coordinates.

[0162] For example, the control unit can obtain the specific position (mouth) and determine the specific coordinates of the mouth according to the acquired portrait data, so as to determine the specific area on the mirror display panel where the lipstick needs to be displayed, i.e., to determine the set area.

[0163] Then, the control unit can retrieve makeup information from the storage unit. Different cosmetic products have different makeup information. After determining the makeup information, the control unit can display the corresponding makeup information on the mirror display panel 30. For example, the control unit can display red on the mirror display panel 30. That is, the selected cosmetic product is applied on the imaging position of the face on the mirror display panel 30 to display the overlay image.
