[0059] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0060] The display device provided in this embodiment replaces the flowing sand with the microsphere 3, thereby avoiding the uneven spots and color patches in the color of the painting caused by directly mixing the quantum dots 6 in the flowing sand. Among them, the display device can be a flowing sand painting, or products such as an hourglass and a display painting.

[0061] Such as Figure 1 、Figure 2 As shown, a specific implementation of the display device provided in this embodiment includes: a cavity 1, the cavity 1 has a receiving cavity 2, at least one side of the receiving cavity 2 is a light-transmitting surface, the receiving cavity 2 is filled with microspheres 3, and the microspheres 3 are loaded with quantum dots 6. A light source assembly 14 is used to emit light so that the light excites the quantum dots 6 to emit light.

[0062] Among them, at least one side of the receiving cavity 2 is a light-transmitting surface, and the viewer can observe the flow of the microspheres 3 in the receiving cavity 2 through the light-transmitting surface. Among them, the total volume of the microspheres 3 can be 25% to 75% of the volume of the receiving cavity 2, preferably 30%. In this way, the microspheres 3 can have sufficient flow space in the receiving cavity 2, so as to realize the flow change of the microspheres 3. This application utilizes the fluorescence characteristics of the quantum dots 6, which can be excited to emit fluorescence after being irradiated by light. Any quantum dots 6 with fluorescence characteristics can be used, and no restrictions are imposed on this. The microspheres 3 loaded with quantum dots 6 in this application are those disclosed in the prior art and can be processed. The material of the microspheres 3 can include quantum dots 6 and polymers. Among them, the quantum dots 6 are located inside the microspheres 3, and the polymer serves as the outer shell of the microspheres 3 to embed the quantum dots 6. The polymer can be polystyrene, etc., and no restrictions are imposed here; the structure of the microspheres 3 can be a core-shell structure, and its material can also include quantum dots 6 and silica. Among them, the quantum dots 6 serve as the outer shell, and the silica serves as the inner core, and the outer shell is arranged on the outer surface of the inner core. Specifically, the preparation method of the microspheres 3 loaded with quantum dots 6 is also the preparation method disclosed in the prior art, and will not be elaborated here. By emitting light from the light source assembly 14 and irradiating the quantum dots 6 loaded on the microspheres 3, the quantum dots 6 are excited to emit fluorescence colors, so that the display device presents a bright and beautiful picture, enhancing the visual effect of the picture. In addition, when the light irradiates the microspheres 3, different visual effects will also be produced based on the refraction and reflection of the light, improving the aesthetic feeling and artistic atmosphere compared with traditional sand paintings. When the light source assembly 14 is turned off, the overall tone of the display device is the color when the quantum dots 6 loaded on the microspheres 3 are not excited. The microspheres 3 can present light red, light blue, light green, light yellow, etc., and no restrictions are imposed here. The whole can present a fresh and elegant picture, giving the viewer an unexpected aesthetic effect. By arranging the microspheres 3 loaded with quantum dots 6 in the receiving cavity 2, instead of the design of mixing quantum dots 6 in the flowing sand in the prior art, it avoids the uneven spots and color patches of the painting color caused by directly mixing quantum dots 6 in the flowing sand.

[0063] Such as Figure 3 、 Figure 4As shown, in this embodiment, the cavity 1 is provided with an opening 7 on its side wall. The opening 7 communicates with the accommodation cavity 2 of the cavity 1. By providing the opening 7, it is convenient to add the microspheres 3 through the opening 7. The cavity 1 is provided with a sealing member 8 for blocking the opening 7. After the microspheres 3 are filled, the opening 7 is blocked, which can ensure that the microspheres 3 will not leak out from the opening 7 during use.

[0064] Specifically, the sealing member 8 includes a rubber plug. Additionally, the sealing member 8 can also be set as a lid, and the lid is threadedly connected to the end of the opening 7.

[0065] As Figure 5 shown, the cavity 1 includes a first substrate 25, a second substrate 26, and a sealing member 10. The first substrate 25 and the second substrate 26 can be glass or plastic, and the first substrate 25 and the second substrate 26 are arranged relatively spaced apart. The sealing member 10 is arranged between the opposite surfaces of the first substrate 25 and the second substrate 26. Specifically, the shapes of the first substrate 25 and the second substrate 26 are both circular, and their sizes are the same. The sealing member 10 is arranged at the edge positions of the first substrate 25 and the second substrate 26. The sealing member 10 has a certain thickness, such that the sealing member 10 and the first substrate 25, the second substrate 26 enclose to form the accommodation cavity 2, and the microspheres 3 are arranged in the accommodation cavity 2. When installing the cavity 1, place the first substrate 25 flat, first bond the sealing member 10 to the first substrate 25 with glue, and then bond and fix the second substrate 26 to the sealing member 10 with glue, thus realizing the installation of the cavity 1. Specifically, the sealing member 10 is made of soft silicone rubber. During later use, a syringe needle can be used to penetrate the sealing member 10 and then extract a part of the air in the accommodation cavity 2. By controlling the size and quantity of the air bubbles, the flow rate of the microspheres 3 can be adjusted; after pulling out the needle, due to the elastic property of the soft silicone rubber material, it can quickly return to its original shape and seal the needle hole. Additionally, the sealing member 10 can also be rubber. Additionally, a liquid such as water, ethanol, etc. can be added to the accommodation cavity 2 to enable the microspheres 3 to flow therein.

[0066] Additionally, as an alternative embodiment, the cavity 1 includes a first substrate 25, a second substrate 26, and a sealing member 10. The sealing member 10 is arranged at the connection between the first substrate 25 and the second substrate 26 to seal the joint. Specifically, the sealing member 10 is a sealant. The first substrate 25 is a cylinder with an open end, and its open end is arranged at one end of the axis. The shape of the second substrate 26 is the same as the shape of the open end of the first substrate 25, and the size of the second substrate 26 is the same as the size of the open end of the first substrate 25. The second substrate 26 is arranged at the open end position of the first substrate 25, and the sealant seals the connection between the two, that is, fixes them in an adhesive manner.

[0067] As Figure 1As shown, in this embodiment, the light source assembly 14 includes: a light emitting member. A plurality of light emitting members are arranged in an array on the circumferential side wall of the cavity 1. Among them, the light emitting member is an ultraviolet lamp, which can emit light with a wavelength of 320 nm - 480 nm. The light irradiates the cavity 1 to excite the quantum dots 6 to emit light. It can be understood that when the light emitting member is arranged on the outer side wall of the cavity 1, the side wall of the cavity 1 is transparent. By arranging the light emitting member on the circumferential side wall of the cavity 1, when in use, the excitation light emitted by the light emitting member can be irradiated towards the accommodation cavity 2, so that all the microspheres 3 in the accommodation cavity 2 are irradiated, so that all the quantum dots 6 are excited to emit fluorescence, further improving the visual effect. In addition, as an alternative embodiment, one light emitting member can be arranged in an array on the cavity 1. In addition, as an alternative embodiment, in addition to the ultraviolet lamp, a fluorescent lamp for daily use lighting can also be arranged on the cavity 1. In addition, the light emitting member can be indirectly connected to the cavity 1, that is, the light emitting member can be arranged on a support member such as a base 16 or a support frame 17 and aligned with the microspheres 3 in the accommodation cavity 2, so that the ultraviolet light emitted by the light emitting member irradiates the quantum dots 6 loaded on the microspheres 3 to emit light.

[0068] Specifically, the light source assembly 14 can also be a separate handheld light source device, such as an ultraviolet flashlight. The viewer can hold the ultraviolet flashlight to irradiate the cavity 1 to excite the quantum dots 6 loaded on the microspheres 3 to emit light, thereby increasing the interactivity between the viewer and the display device. It can be understood that when the light source assembly 14 is a separate handheld light source device, the filter layer 15 can be not provided. In addition, as an alternative embodiment, the light source assembly 14 can also be an ultraviolet headlamp.

[0069] As Figure 1 , Figure 6 As shown, in this embodiment, a partition member 11 is arranged in the accommodation cavity 2 of the cavity 1. The partition member 11 is made of transparent glass material. The partition member 11 is fixedly installed inside the cavity 1 by means of adhesion. The partition member 11 divides the accommodation cavity 2 into a first chamber 12 and a second chamber 13. Among them, the first chamber 12 and the second chamber 13 are distributed in the vertical direction. A plurality of through holes 4 are arranged on the partition member 11 to enable the microspheres 3 to freely pass between the first chamber 12 and the second chamber 13, so as to form a beautiful picture. In addition, as an alternative embodiment, the partition member 11 can also be not provided, as long as the microspheres 3 flow in the cavity under the action of gravity. In addition, as an alternative embodiment, a plurality of partition members 11 can also be arranged, so as to divide the cavity into multiple spaces. In addition, as an alternative embodiment, the partition member 11 can also be integrally formed with the cavity 1. In addition, as an alternative embodiment, the partition member 11 can also be made of transparent hard plastic. In addition, as an alternative embodiment, the partition member 11 can also be set to be semi-transparent or frosted.

[0070] Specifically, the diameter of the through hole 4 is 500 μm. At this time, the diameter of the through hole 4 enables the microspheres 3 to pass through freely. In addition, those skilled in the art can also adjust the diameter of the through hole 4 to ensure that the microspheres 3 can pass through freely. For example, the diameter of the through hole 4 can be 800 μm, 1 mm, etc. This application does not limit this.

[0071] As Figure 7 shown, in this embodiment, the display device further includes a light filtering layer 15, and the light filtering layer 15 is at least provided on the light transmissive surface of the accommodating cavity 2. The light filtering layer 15 can be provided on the outer surface of the light transmissive surface facing the viewer, can also be provided on the inner surface of the light transmissive surface away from the viewer, or can be provided on both the outer surface of the light transmissive surface facing the viewer and the inner surface away from the viewer. There is no limitation on this. The ultraviolet light emitted by the light source assembly 14 is filtered by the light filtering layer 15, so that other colored lights can pass through, thereby reducing the irradiation time of ultraviolet light on the human body and reducing the damage to the human skin and eyes. In addition, as an alternative embodiment, the light filtering layer 15 can also be not provided.

[0072] As Figure 1 、 Figure 3 shown, in this embodiment, it further includes: a base 16, and the base 16 is detachably connected to the cavity 1. The base 16 can be placed on a plane. The viewer can disassemble the cavity 1 from the base 16 and manually turn the cavity 1 so that the microspheres 3 flow from top to bottom in the cavity 1 to form an image. In addition, as an alternative embodiment, the base 16 can also be rotatably connected to the cavity 1, so that the cavity 1 can be turned horizontally on the base 16, thereby enabling the microspheres 3 to flow from top to bottom in the cavity 1 to generate an image.

[0073] As Figure 3 shown, in this embodiment, a groove 18 is provided on the upper end surface of the base 16 for plug-in connection with the bottom of the cavity 1. The groove 18 is strip-shaped, and the bottom of the cavity 1 can be directly plugged into the groove 18. The overall structure is simple, which is convenient for the viewer to take down the cavity 1 from the groove 18 at any time for appreciation.

[0074] As an alternative embodiment, a clamping member 19 that is inserted and mated with the groove 18 may also be provided at the bottom of the cavity 1. During installation, the clamping member 19 is inserted into the groove 18 of the base 16, and the microspheres 3 start to flow freely and form an image. Further, a clamping member 19 that is inserted and mated with the groove 18 may also be provided at the top of the cavity 1. The viewer can remove the clamping member 19 at the bottom of the cavity 1 from the groove 18, and after flipping, insert the clamping member 19 at the top of the cavity 1 into the groove 18 to fix the cavity 1, so that the cavity 1 can be conveniently flipped. Among them, the cross-section of the groove 18 is rectangular, and the clamping member 19 is a corresponding rectangular column. Additionally, as an alternative embodiment, the cross-section of the groove 18 is circular, and the clamping member 19 is a cylinder. At this time, after the clamping member 19 of the cavity 1 is inserted into the groove 18, the cavity 1 can rotate around the axis of the cylinder on the base 16.

[0075] As Figure 1 shown, in this embodiment, it further includes: a support frame 17, the cavity 1 is rotatably connected to the support frame 17, and the support frame 17 is detachably connected to the base 16. The specific ways of detachable connection include threaded connection, hinged connection, etc. At this time, when it is necessary to rotate the cavity 1, only manual driving is required to flip the cavity 1 on the support frame 17, which is convenient and fast. The support frame 17 is detachably connected to the base 16. When it is necessary to package and transport the display device, the support frame 17 can be separated from the base 16, which is convenient for packing and transporting. As Figure 1 shown, in this embodiment, the support frame 17 is semi-circular, similar to a "U" shape. The inner sides of both ends of the support frame 17 are respectively rotatably connected to the cavity 1. The cavity 1 rotates around the rotation point as the center, and at the same time, both ends of the support frame 17 are rotatably connected to the cavity 1, so the support stability of the support frame 17 for the cavity 1 is better. Additionally, as an alternative embodiment, the support frame 17 can also be set as an arc, one end of the arc is rotatably connected to the cavity 1, and the other end is inserted and connected to the base 16. Additionally, as an alternative embodiment, the support frame 17 is a complete circular ring, and the cavity 1 is arranged inside the support frame 17.

[0076] Specifically, an adsorption component may also be provided on the upper end surface of the base 16. The adsorption component includes: a magnet, and a part of the support frame 17 is made of a material that can be magnetically connected to the magnet, so that the support frame 17 can be quickly disassembled from the base 16. Additionally, as an alternative embodiment, a magnet can also be provided on the support frame 17, and the magnet on the base 16 is used to connect and fix with the magnet on the support frame 17, which is also convenient for disassembly and storage.

[0077] Specifically, the base 16 is provided with a foldable part, which has a first state of supporting the support frame 17 after expansion and a second state after folding. The foldable part is: four legs provided on the lower end surface of the base 16, and the four legs are respectively arranged at the four corner positions of the lower end surface of the base 16, and the upper ends of the legs are rotatably connected to the base 16. When in use, rotate the legs so that the legs are perpendicular to the lower end surface of the base 16, and the four legs are used to support the base 16. When storage is needed, the legs can be folded and retracted. The foldable part can increase the support stability of the base 16. In addition, as an alternative implementation, the foldable part can also be: legs that can be bent. The legs are divided into two sections. One end of the first section of the leg is rotatably connected to one end of the second section of the leg, and the other end of the first section of the leg is rotatably connected to the lower end surface of the base 16. The legs can rotate the second section of the leg upward around the rotation point to fold it.

[0078] In addition, as an alternative implementation, as Figure 8 shown, the support frame 17 can also be integrally formed with the base 16. Integral formation facilitates the subsequent installation of the display device. Only by installing the cavity 1 on the support frame 17 can the installation requirements be completed.

[0079] At the same time, in order to facilitate the protection of the cavity 1 and more convenient fixation, as Figure 8 shown, the cavity 1 is installed in the protection component. The protection component includes: a first protection part 23 and a second protection part 24. The cross-sectional shapes of the first protection part 23 and the second protection part 24 are both "L" shapes, and their sizes are equal. The first protection part 23 and the second protection part 24 are detachably connected by bolts and can form a space for accommodating the cavity 2. At this time, the first protection part 23 and the second protection part 24 are clamped on both sides of the cavity 1. The first protection part 23 and the second protection part 24 are detachably connected to form a U-shaped groove. At the same time, the light source component 14 can be set as a strip-shaped ultraviolet LED light strip, and the ultraviolet LED light strip is arranged in the U-shaped groove. Of course, the above description is not restrictive, and the first protection part 23 and the second protection part 24 can also be detachably connected by means of snap connection. The first protection part 23 and the second protection part 24 can also be an integrally formed structure.

[0080] In addition, as an alternative implementation, the support frame 17 can be not provided, and the cavity 1 is connected to the base 16. Specifically, a groove 18 is provided on the upper end surface of the base 16, and the support frame 17 is provided with a connecting part corresponding to the groove 18. The connecting part of the support frame 17 is inserted into the groove 18 to realize the installation of the support frame 17 and the base 16.

[0081] As Figure 1 、 Figure 3As shown, in this embodiment, a power supply component 9 is further provided. The power supply component 9 is electrically connected to the light source assembly 14 and is disposed inside the base 16 or the support frame 17. The power supply component 9 supplies power to the light source assembly 14 to facilitate the light source assembly 14 to emit light. The power supply component 9 can be a lithium battery or other power supply devices capable of supplying power to the light source assembly 14, and there is no limitation thereto.

[0082] As Figure 1 , Figure 3 shown, in this embodiment, a charging interface 5 is further included. The charging interface 5 is disposed on the base 16 or the support frame 17 and is electrically connected to the power supply component 9. After the charging interface 5 is connected to an external power supply, the power supply component 9 can be charged without replacing the power supply component 9. The charging interface 5 is a USB interface. Additionally, as an alternative embodiment, the charging interface 5 can also be set as a type-c interface.

[0083] This application further provides an application device with a display device, including the display device, and the display device adopts the display device as described above. The application device with a display device can be a mobile phone case, a measuring tape, an alarm clock, a keychain, a stationery box, etc.

[0084] As Figure 9 , Figure 10 shown, the application device with a display device includes a housing 20. A receiving groove 21 for receiving a smart terminal is provided on one side of the housing 20, and the aforementioned display device is provided on the other side of the housing 20.

[0085] Specifically, the application device with a display device is a mobile phone case, the smart terminal is a mobile phone, and the mobile phone can be snapped into the receiving groove 21 for fixation. The other side of the housing 20 is fixedly connected to the aforementioned display device by means of adhesion. When the display device is fixed to the mobile phone case and the mobile phone is installed on the receiving groove 21 of the housing 20, by shaking or moving the mobile phone, the microspheres 3 flow in the cavity 1, presenting a flowing visual effect and improving the overall aesthetics of the mobile phone case. Additionally, the smart terminal can also be a device such as a tablet computer.

[0086] In addition, the description of the mobile phone case above is not restrictive. As Figure 11 , Figure 12As shown in the figure, the lower end surface of the base 16 of the display device can also be rotatably connected to the back of the mobile phone case. Specifically, two connecting blocks are provided on the back of the mobile phone case and extend outward perpendicular to the back surface. The two connecting blocks are respectively arranged at both ends of the base 16 in the length direction. On the opposite side end surfaces of the two connecting blocks, rotating shafts extend towards the base 16 respectively. The rotating shafts are rotatably connected to the base 16, and the rotating shafts are connected at the corner positions between the lower end surface and the side end surface of the base 16. Additionally, as an alternative implementation, the lower end surface of the base 16 can be set as a semi-circular arc, and the rotating shaft is concentric with the semi-circular arc. At this time, the display device has two usage states. The first is that the cavity 1 abuts against the back of the mobile phone case, and by rotating or flipping the mobile phone case, the microspheres 3 in the cavity 1 are caused to flow. The second is to rotate the base 16 around the rotation point between the base 16 and the mobile phone case until the base 16, the support frame 17, and the cavity 1 are perpendicular to the back of the mobile phone case. At this time, by flipping the cavity 1, the cavity 1 can be rotated around the rotation point between the cavity 1 and the support frame 17, so that the microspheres 3 flow.

[0087] As Figure 11 shown, the application device with the display device includes a device body 22, and a measurement scale area is provided on the device body 22, and the measurement scale area is arranged opposite to the aforementioned display device.

[0088] Specifically, as Figure 13 shown, the application device with the display device is a measuring scale. The measuring scale can be in a long strip shape. A measurement scale area is provided on the long strip-shaped measuring scale, and this area is used to measure length; the measuring scale can also be circular or semi-circular, and the measurement scale area on it is used to measure angles. The display device is fixed on the measuring scale by gluing and is arranged opposite to the measurement scale area, so that the display device does not block the measurement scale area. When in use, the scale on the measuring scale is used to measure the size of an object; when not in use, by rotating the measuring scale, the microspheres 3 in the display device flow to generate an image, thereby enhancing the fun of using the measuring scale.

[0089] In addition, the description of the mobile phone case above is not restrictive. As Figure 14As shown, the lower end face of the base 16 of the display device is rotatably connected to the side face of the measuring scale. Among them, the connection between the base 16 and the side end face of the measuring scale is a rotational connection. On the side end face of the measuring scale, there are connection blocks extending outward perpendicular to the side end face of the measuring scale, and the connection blocks are arranged at both ends in the length direction of the base 16. On the inner end face of the connection block, a rotating shaft extends towards the base 16, and the rotating shaft is rotatably connected to the base 16. At this time, the cavity 1 is rectangular, and the thickness of the cavity 1 is slightly lower than the thickness of the measuring scale, so that the display device can rotate around the rotating shaft, and the rotated display device is perpendicular to the side end face of the measuring scale. Specifically, after the rotational connection, the display device has two usage states on the measuring scale, which are the same as the states of the mobile phone case and the display device described above, and will not be elaborated here. Additionally, as an alternative implementation, if the measuring scale is a semi-circular protractor, the display device can be arranged on the straight edge.

[0090] Usage method of the display device: A power supply component 9 is arranged in the base 16, and the charging interface 5 on the base 16 is electrically connected to the power supply component 9. A groove 18 is arranged at the upper end of the base 16, and a clamping component 19 is arranged at the lower end of the support frame 17. The clamping component 19 is inserted into the groove 18 for fixation, so that the support frame 17 is installed on the base 16. The inner sides of both ends of the support frame 17 are rotatably connected to the cavity 1. The light source component 14 can be an ultraviolet lamp arranged on the outer side face of the cavity 1. The microspheres 3 loaded with quantum dots 6 flow from top to bottom in the accommodation cavity 2, and the light source component 14 irradiates the microspheres 3 loaded with quantum dots 6, thereby exciting the quantum dots 6 to emit light. The bright and rich fluorescent colors emitted by the quantum dots 6 enhance the visual experience of the viewers.

[0091] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
