[0001] Cross-Reference This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 650,586, filed May 22, 2023, which is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates to artificial nails, and more particularly, to an integrated digital nail system and related methods for programming a color display in an artificial nail. Background Art

[0003] Nail polish is typically applied to a person's nails for decorative purposes. In this process, a variety of items are usually required. These items may include nail polish containers, nail polish remover containers, top coat containers, base coat containers, nail polish remover pads, nail clippers, nail pliers, nail files, etc.

[0004] Furthermore, these items may be misplaced, causing the user to spend time searching for them and / or incur replacement costs. Additionally, nail polish often cracks and fades shortly after application, exposing the unpainted nail underneath. While users can reapply nail polish themselves, this self-reapplication may not be convenient when needed.

[0005] Furthermore, the use of certain fluids often presents risks of harmful fumes, flammability, and / or spillage onto user property. Like healthy adults, immunocompromised patients frequently visit nail salons and perform their own nail art at home. The health concern is that exposure to toxic industrial chemicals through inhalation or skin contact can have adverse effects on human health. Nail polish is made from toluene, formaldehyde, nickel, lead, and tin. Nail polish remover uses organic solvents. For some individuals, the combined effects of these chemicals may even lead to cancer or autoimmune diseases.

[0006] As an alternative to applying nail polish, users can opt for artificial nails, which allow them to achieve a nail appearance similar to polished nails without using all the aforementioned nail polish-related items. However, a drawback of artificial nails is that users are limited to specific nail polish colors or patterns on the artificial nails. Changing the color requires a different set of artificial nails.

[0007] One method to overcome the limitations of using pre-colored artificial nails is to use artificial nails with a color display that allows the user to change the color of the artificial nail. Artificial nails with a color display are disclosed in U.S. Patent Application No. 2016 / 0295989. This system includes a nail covering device comprising a body configured to mate with a user's fingernail, a display associated with an upper surface of the body, and a receiving unit for communicating with a pattern transmission device. The display uses electrophoretic ink to display the pattern.The system also includes a pattern transmission device comprising a housing containing a processing unit and a storage unit for storing at least one pattern, wherein the pattern transmission device is configured to transmit the at least one pattern to a nail covering device. A server storing multiple patterns is communicatively connected to the pattern transmission device. A user uses an application running on a user-associated mobile device to transmit the at least one pattern from the server to the pattern transmission device.

[0008] Another method for artificial nails with a color display is disclosed in U.S. Patent No. 8,863,759. A cosmetic device for application to artificial nails, wherein the device includes an electrochromic multilayer structure comprising an electrosensitive stack. The electrosensitive stack is formed of at least a first electrode layer and a second electrode layer, wherein the first electrode layer and the second electrode layer are coatings supported by respective support layers. The support layer comprises a single flexible membrane or a component of multiple flexible membranes, a first active electrochromic layer and a second active electrochromic layer, and an electrolyte layer. The cosmetic device also includes an optically active layer, which is at least partially stacked on an electrosensitive stack. The optically active layer comprises at least one of effect pigments, a coloring layer, a luminescent layer, and a print.

[0009] Nevertheless, there is still a need to improve artificial nails with color displays and how to program the color displays. Summary of the Invention

[0042] This specification is set forth with reference to the accompanying drawings, in which exemplary embodiments are shown. However, many different embodiments may be used, and therefore this specification should not be construed as limiting itself to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. The same reference numerals throughout refer to the same elements, and superscript symbols may be used to indicate similar elements in different embodiments.

[0043] Referring first to FIG. 1, an integrated digital nail system 120 includes a client device 130 and an artificial nail assembly 160, the artificial nail assembly 160 having a color display 162 bonded to the underside of a nail blank 192. The color display 162 is programmable to display one or more user-selected colors. The artificial nail assembly 160 is to be bonded to a user's nail, which may be a fingernail or a toenail.

[0044] The integrated digital nail system 120 avoids the use of fluid nail polish chemicals, which typically produce harmful fumes and flammable conditions. Health problems that could adversely affect human health due to exposure to toxic industrial chemicals through inhalation or skin contact are advantageously avoided.

[0045] The client device 130 may be a desktop computing device or a mobile computing device. Mobile computing devices include, for example, cellular phones or personal display assistants (PDAs).The client device 130 includes a nail color application 132 configured to display a set of color options 134 available for use with a color display 162. Each color option 134 has at least one color file 136 associated with it. Each color file 136 includes a programming signal value corresponding to the color option 134.

[0046] The integrated artificial nail assembly 160 includes a chipset and a power layer 200. The chipset and power layer 200 include a chipset 202 and a power supply 204 coupled to the chipset 202, wherein the chipset 202 communicates directly with the client device 130 to program the color display 162 to display one or more user-selected colors.

[0047] The color display 162 includes a first conductive layer 170 (also referred to as a first electrode), an electronic paper layer 172, and a backplate 166. A transparent protective layer 190 covers the first conductive layer 170. The protective layer 190 is a thermoplastic polymer, such as polyethylene terephthalate (PET). The first conductive layer 170 is a transparent conductive material, such as indium tin oxide (ITO).

[0048] In one embodiment, the electronic paper layer 172 is an electrophoretic layer. In other embodiments, the electronic paper layer 172 (see specification 4 / 10 pages 9 CN 122070069 A) may be, for example, an electrochromic layer. For the purposes of discussing the color display 162, the electronic paper layer 172 is configured as an electrophoretic layer.

[0049] Electronic paper is a technology that replicates the appearance of ordinary ink on paper. It works by using tiny capsules filled with a transparent fluid containing tiny particles, each about the width of a human hair. These capsules are arranged in a thin film containing particles of different colors and charges. The charge is initially set at the factory so that the capsules remain charged. When an electric field is applied to the respective electrodes (i.e., the first conductive layer 170 and the second conductive layer 176), the particles move within the charged capsules, thereby causing the electronic paper layer 172 to exhibit a certain color.

[0050] The backplate 166, also referred to as a custom backplate, is configured to enable the color display 162 to function properly within the integrated artificial nail assembly 160 and to be programmed via the chipset 202. The backplate 166 includes a support layer 174, a second conductive layer 176 located on the upper surface of the support layer 174, and a plurality of traces 178, 179 located on the lower side of the support layer 174. The second conductive layer 176 may also be referred to as a second electrode. The support layer 174 may be a thermoplastic polymer.

[0051] The second conductive layer 176 is a conductive material and does not need to be transparent. Exemplary conductive materials are carbon, copper, silver, and gold. The second conductive layer 176 may be segmented, each segment being individually controlled to configure the electronic paper layer 172 to display a different color. The traces 178, 179 are also conductive materials, such as silver.The second conductive layer 176 and the traces 178, 179 are printed on opposite sides of the support layer 174.

[0052] The backplate 166 further includes a plurality of vias 180, 182 extending between the plurality of traces 178, 179 and the first conductive layer 170 and the second conductive layer 176. Via 180 extends between a first trace in trace 178 and the first conductive layer 170. Via 182 extends between a second trace in trace 179 and the second conductive layer 176.

[0053] The chipset and power layer 200 are adjacent to the underside of the support layer 174. The chipset and power layer 200 are shown as being on the same layer, but in other embodiments, the chipset 202 and the power layer 204 are on different layers. The chipset 202 is electrically coupled to the plurality of traces 178, 179. The functionality of the chipset 202 may be provided by a single application-specific integrated circuit (ASIC) or by a collection of multiple individual chips.

[0054] The chipset 202 may be Bluetooth® compatible for communicating with the client device 130. The chipset 202 is used to receive at least one color file 136 corresponding to at least one user-selected color option 134, and generate a programming signal corresponding to the programming signal value provided by the received at least one color file 136 to program the color display 162 to the at least one user-selected color option 134.

[0055] Each microcapsule in the electronic paper layer 172 may include red, green, and yellow (RGY) pigments. The programming signal value in the color file 136 provides a voltage potential to be applied to the color display 162, and the duration for which the voltage potential needs to be applied. The voltage potential may be applied to the color display 162 within one time period, or it may be applied within multiple time periods. For example, a time period may fall within the range of microseconds or milliseconds.

[0056] Referring now to Figures 2A-2B, for a color display 162 configured as a monochrome display, the relative top and bottom sides of the support layer 174 will be discussed. A second conductive layer 176 is printed on the top side of the support layer 174 as a continuous segment, as shown in Figure 2A. Similarly, a first conductive layer 170 is also printed as a continuous sheet.

[0057] A small area of ​​the support layer 174 is not covered by the second conductive layer 176 to allow vias 180 to pass through without contacting the second conductive layer 176. A first trace 178 and a second trace 179 are printed on the bottom side of the support layer 174, as shown in Figure 2B. A via 180 extends from the first trace 178 to the first conductive layer 170, and a via 182 extends from the second trace 179 to the second conductive layer 176.

[0058] The chipset 202 is electrically connected to the first trace 178 and the second trace 179.This allows the chipset 202 to form an electrical contact with the first conductive layer 170 via via 180 (see page 5 / 10 of the specification, CN 122070069 A 180) and an electrical contact with the second conductive layer 176 via via 182.

[0059] When the chipset 202 applies a voltage difference to the first electrode 170 and the second electrode 176, the capsules in the electronic paper layer 172 are all set to the same color. The electronic paper layer 172 is presented as a single pixel. As an example, the voltage difference may be based on applying a ground voltage to the first electrode 170 and a 24-volt voltage to the second electrode 176. The voltage difference is based on the chipset 202 generating programming signals corresponding to programming signal values ​​provided by the color file 136 at predefined time intervals, wherein the programming signal values ​​program the color display 166 to the color option desired by the user.

[0060] Referring now to Figures 3A-3B, for the color display 162 configured as a multicolor display, the relative top and bottom sides of the support layer 174 will be discussed. This requires the first conductive layer 170 or the second conductive layer 176 to be divided into segments, wherein each segment is electrically isolated from the other segments and can be individually controlled with different voltage levels. As an example, the second conductive layer 176 may be divided into second conductive layer segments 176(1) and 176(2) for French nail patterns, as shown in FIG3A. Gap 177 electrically isolates the second conductive layer segments 176(1) and 176(2).

[0061] Since there are now two second conductive layer segments 176(1) and 176(2) for French nail patterns, additional traces and vias are required, as shown in FIG3B. The first trace 178 is still connected to the first conductive layer 170 via via 180. The second trace 179 is now divided into second traces 179(1) and 179(2). The second trace 179(1) is used to connect to the second conductive layer segment 176(1) via the through-hole 182(1), and the second trace 179(2) is used to connect to the second conductive layer segment 176(2) via the through-hole 182(2).

[0062] One advantage of switching the color display 166 at the second conductive layer segments 176(1), 176(2) is that since the first conductive layer 170, which is formed as a single continuous layer, only requires one contact (i.e., the through-hole 180), there will be fewer interruptions in the color display 162. Dividing the first conductive layer 170 into multiple segments would require multiple contacts, and since the first conductive layer 170 is transparent, this would result in more interruptions in the color display 162. In contrast, the contacts for the second conductive layer segments 176(1), 176(2) are invisible.

[0063] The second conductive layer segments 176(1), 176(2) are second electrodes that are controlled separately.When a voltage difference is applied to the first electrode 170 and the second electrode 176 (1), the corresponding capsules in the electronic paper layer 172 located between the first electrode 170 and the second electrode 176 (1) are all set to the same first color. When a different voltage difference is applied to the first electrode 170 and the second electrode 176 (2), the corresponding capsules in the electronic paper layer 172 located between the first electrode 170 and the second electrode 176 (2) are all set to the same second color, different from the first color. As described above, the voltage difference generates a programming signal corresponding to the programming signal value provided by the color file 136 at a predefined time interval based on the chipset 202, wherein the programming signal value programs the color display 166 to the color option desired by the user.

[0064] In order for the color display 166 to display more than the first color and the second color, the second conductive layer will be further divided into more than two second conductive layer segments. Each second conductive layer segment requires its own traces and vias. As will be readily understood by those skilled in the art, each second conductive layer segment may be shaped such that desired patterns, symbols, designs or alphanumeric values ​​can be displayed.

[0065] Referring now to FIG4, an alternative design for the second conductive layer 176 and the first trace 178 and the second trace 179 is based on configuring the second conductive layer 176' with tails 178', 179'. Tail 178' serves as the first trace 178, and tail 179' serves as the second trace 179. Tails 178', 179' are flexible, allowing them to fold from the top side to the bottom side of the second conductive layer 176'.

[0066] Tails 178', 179' may be printed separately from the second conductive layer 176' and then folded onto the top side of the support layer 174'. Alternatively, tails 178', 179' may be printed simultaneously with the second conductive layer 176', such that tail 179' is an extension of the second conductive layer 176'. Specification 6 / 10 pages 11 CN 122070069 A

[0067] The tail 179' is in electrical contact with the second conductive layer 176'. This advantageously avoids the need for the through-hole 182, since there is an electrical connection between the second conductive layer 176' and the tail 179'. Since the tail 178' is used to connect to the through-hole 180', the tail 178' is electrically isolated from the second conductive layer 176'. The through-hole 180' extends between the top side of the first conductive layer 170 and the support layer 174'. Since the tail 178' folds from the top side of the second conductive layer 176' to the bottom side, there is no need to connect the through-hole 180' to the bottom side of the support layer 174'.

[0068] Referring back to FIG1, the power source 204 may be a battery, such as a micro battery, a solid-state micro battery, or a nuclear diamond battery. The micro battery may be referred to as an electrochemical battery micro battery, which uses a liquid, paste, or gel as an ion conducting medium and consumes ion resources.The electrochemical battery may be conformal in shape to a fingernail, rechargeable, breathable, and / or bio-interactive. The solid-state microbattery uses a solid electrolyte for ion conduction between electrodes and consumes ion resources. The solid-state microbattery may be conformal in shape to a fingernail, rechargeable, breathable, and / or bio-interactive. The nuclear diamond battery is a β-voltaic battery that operates by converting the energy released by decaying isotopes into electrical energy. It can generate electrical energy for an extremely long time (decades or longer) without charging or maintenance. The nuclear diamond battery may be conformal in shape to a fingernail.

[0069] In other embodiments, the power supply 204 may be configured as a near-field communication (NFC) chipset that operates similarly to Apple Pay™. The NFC chipset receives power and at least one color file 136 corresponding to at least one user-selected color option via inductive coupling with the client device 130. The client device 130 includes a corresponding NFC chipset.

[0070] In other embodiments, the power source 204 may include a supercapacitor configured to be charged by connecting to an external power source, receiving and converting solar energy, or any number of radio frequency energy absorption and conversion processes. The supercapacitor may also be referred to as a supercapacitor and may be conformally shaped to a fingernail. The supercapacitor is a high-capacitance capacitor with a capacitance value far exceeding that of a solid-state capacitor but a lower voltage limit. It fills the gap between electrolytic capacitors and rechargeable batteries.

[0071] The integrated artificial nail assembly 160 may further include a power input layer 206 for charging the power source 204. The power input layer 206 may be a photovoltaic cell located below the chipset and power layer 200 and may be conformally shaped to a fingernail. Although not shown in the figures, the photovoltaic cell may alternatively be configured as a transparent photovoltaic cell disposed adjacent to the upper surface of the first conductive layer 170. The photovoltaic cell is integrated into a protective layer 190 and / or integrated into a second conductive layer 176 and may be conformally shaped to a fingernail. Any of these cases is used to convert photon energy into electrical potential energy for storage in power supply 204. The photovoltaic cell generates electrical energy from ambient light or provided visible light. In other embodiments, the photovoltaic cell may also be used as an optical detector for receiving from client device 130 at least one color file corresponding to at least one user-selected color option.

[0072] The integrated artificial nail assembly 160 may further include a nail interface adapter 194 that engages between the upper surface of the user's nail and the lower surface of the power input layer 206. If the integrated artificial nail assembly 160 does not include the power input layer 206, the nail interface adapter 194 engages with the lower surface of the chipset and power layer 200.

[0073] Referring now to Figures 5A-5C, different views of the artificial nail assembly 160 are provided. Human nails have curvature both along the finger axis and in the axis perpendicular to the finger. That is, the upper surface of a human nail has a composite curvature shape because there are two curvature axes. Therefore, the upper surface 193 of the nail preform 192 has a composite curvature shape to aesthetically resemble a natural nail.

[0074] However, there are physical limitations to the mechanical layout and / or material composition of the color display 162. These limitations may constrain or otherwise determine how the layers optimally bend or flex to engage with the underside of the nail preform 192. Since mechanical stress causes strain on the electronic paper layer 172, this can negatively affect the performance of the color display 162, and thus the physical limitations may cause the color display 162 to have a lower-than-desired composite curvature shape. In other words, there are physical limitations to the extent to which the color display 162 can bend or flex to engage with the underside of the nail preform 192. Preferably, the color display 162 is bent into a conformal curvature shape rather than a composite curvature shape.

[0075] As best shown in FIG6, the color display 162, chipset and power layer 200, and power input layer 206 can be characterized as an integrated color display 163 because the different layers are bonded together. The upper surface 167 and lower surface 168 of the integrated color display 163 are bent about a single axis. That is, the upper surface 167 and lower surface 168 of the integrated color display 162 each have a single axis of curvature.

[0076] In order to engage the nail blank 192 with the upper surface 168 of the integrated color display 163, the bottom surface 195 of the nail blank 192 is formed to have a single axis of curvature. In order to firmly bond the lower surface 167 of the integrated color display 163 to the upper surface of the user's nail, a nail interface adapter 194 is provided. The lower surface 197 of the nail interface adapter 194 has a composite curvature shape to securely engage with the user's nail, and the upper surface 199 of the nail interface adapter 194 has a single curvature shape to engage with the lower surface 167 of the integrated color display 163.

[0077] The nail preform 192 can be formed by injection molding. The three-dimensional curvature of the artificial nail assembly 160 is achieved by physical surface-to-surface bonding of the integrated color display 163 to a precast thermosetting polymer. The precast thermosetting polymer acrylic nail preform 192 may be, for example, an acrylic nail preform 192. The bonding of the integrated color display 163 to the polymer nail preform 192 is accomplished using an optically clear adhesive, thereby forming an adhesive optical system. The integrated color display 163 is attached to the user's nail using the precast nail interface adapter 194, wherein the nail interface adapter 194 is fixed to the surface of the user's nail using an optically clear adhesive.

[0078] The stack thickness of the artificial nail assembly 160 can be between 5 and 15 mils, including an integrated color display 163 with a thickness of 3 to 7 mils, one or more adhesive layers with a thickness of 1 mil, and an optically clear polymer overlay element nail preform 192 with a thickness of 1 to 10 mils. Conventional thermosetting polymer casting equipment for the nail preform 192 can be used to hot press sheet polymers, blow mold, cast separately, or directly melt-cast onto the integrated color display 163. Although not shown, stereolithography resin fusion can be used to create one or more sub-components or as a method of manufacturing an outer encapsulation.

[0079] The surface of the nail preform 192 can be modified to adjust various parameters to enhance the underlying color of the artificial nail assembly 160, change its prismatic visual effect, amplify desired optical effects, or minimize undesirable optical effects. One example of surface modification is laser ablation surface modification, in which the exposed surface 193 of the nail preform 192 or the final artificial nail assembly 160 is etched to optically alter the path of light through the nail preform 192. As an example, as shown in Figures 7A-7B, triangular lines 223 can be etched into the upper surface 193 of the nail preform 192.

[0080] The uppermost surface 193 of the nail preform 192 can be a pre-formed thermosetting resin shell that can be modified by laser energy surface ablation, thereby etching fine lines, curves, or geometric patterns into the uppermost surface 193. The volume of material constituting the etching is effectively removed to establish a lower surface morphology along the length of the nail preform 192 or in any desired repeating pattern, thereby achieving the desired optical effect. The illustrated example of color enhancement is based on repeating parallel lines extending from the back to the tip along the length of the nail preform 192.

[0081] The physical basis for allowing optical alterations to occur on the uppermost surface 193 and affecting the underlying color is the creation of constructive and / or destructive interference patterns on the surface of the artificial nail assembly, thereby altering the path of light through the outer protective shell of the artificial nail assembly 160. Certain ablation characteristics can be modified to achieve specific optical effects.

[0082] Ablation characteristics include the substrate material, ablation depth, width, ablation profile, energy frequency, ablation rate, substrate material surface roughness, ablation surface roughness, pattern, pattern width, optical properties of the polymer outer coating, thermal deformation properties of the substrate material, and the wavelength of the underlying color to be optimized. Once the ablation processing parameters are determined, the physical pattern is ablated onto one or more surfaces of the pre-formed thermosetting resin shell nail blank 192 and / or the outer surface of the final artificial nail assembly 160.

[0083] Another example of surface modification via laser ablation is the generation of microbubbles within the nail shell for prism optical alteration.As shown in Figures 8A-8B, dual lasers are used to alter the subsurface 225 of the nail preform 192 to generate microbubbles 227, thereby optically altering the path of light through the nail preform 192.

[0084] Laser ablation surface modification can adjust various parameters to enhance the prismatic effect of the patterned microbubbles 227 formed within the acrylic shell of the nail preform 192. Selective reflection of light within the patterned microbubbles 227 can produce the desired optical effect on the final artificial nail assembly 160. The preformed thermosetting resin nail preform 192 or shell can be modified by laser energy cavity ablation to form microbubbles 227 within the volume of the nail preform 192 to achieve a light scattering effect. The formation of microbubbles 227 in the material will induce physical stress in the optical material, inducing various prismatic optical ray scattering, including polarization, chromatic aberration, cavity reflection, and absorption. Careful arrangement of the microbubble pattern can achieve the desired optical effect. This color enhancement example is based on microcavity ablation and void generation within the nail shell material.

[0085] The physical basis for allowing optical alterations to the volume and underlying color representation of the nail preform 192 is the reconstruction of incident light into a unique and contrast-enhancing pattern within the transparent surface of the nail preform 192. Typically, light entering the surface of the artificial nail assembly, penetrating to the color layer, reflecting from the color layer, passing through the acrylic shell, and exiting from the top surface of the nail, will now have to interact with micropores in the transparent material that have irregular internal reflective surfaces, variable refractive indices, polarization, and light absorption properties.

[0086] To achieve specific optical effects, the ablation characteristics of the substrate material, microcavity generation characteristics, cavity depth, cavity width, energy frequency, cavity volume rate, substrate material surface roughness, ablated surface roughness, pattern, optical properties of the substrate material, thermal deformation characteristics of the substrate material, and the refractive indices of the substrate material and the ablated surface can be altered. Once the processing parameters resulting from microcavity ablation are determined, the physical pattern is etched into the transparent volume of the preformed acrylic nail preform 192 and / or onto the final artificial nail assembly 160.

[0087] Referring now to FIG. 9, the integrated digital nail system 120 may include a nail access code 530, which must be received by a nail color application 132 in a client device 130 before the integrated artificial nail assembly 160 is programmed. The nail access code 530 is used to activate the nail color application 132.

[0088] The nail access code 530 may be placed on the box or packaging containing the integrated artificial nail assembly 160 when purchased by the user. The nail access code 530 may be, for example, a QR code or barcode, scanned by a camera on the client device 130. In other embodiments, the nail access code 530 may be manually entered by the user into the client device 130.

[0089] The electronic paper layer 172 within the color display 162 of the artificial nail assembly 160 may vary with temperature. The client device 130 includes a temperature sensor 138 that provides temperature values. The client device 130 uses these temperature values ​​to select a color file 136 corresponding to that temperature value. In other words, each corresponding color option 134 may have multiple color files 136 for that color option 134. The programming signal value in the color file 136 for the corresponding color option 134 varies between different temperature values. In other embodiments, the temperature is determined by the artificial nail assembly 160.

[0090] After the nail color application 132 is activated, data associated with the user programming the integrated artificial nail assembly 160 may be relayed to a cloud-based data collection server 540. Example data collected by the client device 130 and stored in the data collection server 540 may include user trend lines, timestamps, location, demographic information, palette sharing, etc. The stored data may be referred to as a data lake. Instruction manual, pages 9 / 10, 14 CN 122070069 A

[0091] Referring now to Figures 10A-10B, the nail polish application 132 provides a relatively intuitive user interface for programming the integrated artificial nail assembly 160. Example screenshot 300 of the nail polish application 132 shows a variety of different colors and color themes for the user to view and select. The colors may include a trending color 302, a featured palette color 304, a “What’s your style?” color 306, and more palette colors 308. As an example, more palette colors 308 include a soft oasis color 310 and an earthy tranquility color 312.

[0092] To begin selecting one or more colors for the integrated artificial nail assembly 160, the user taps the UI interface 314 to connect to the integrated artificial nail assembly 160. Once connected, the user is able to select the one or more colors, which are displayed in the prompt area 316 in screenshot 320. To transfer the user-selected color to the integrated artificial nail assembly 160, the user selects the prompt area 318.

[0093] Another aspect relates to a method for manufacturing an integrated artificial nail assembly 160, comprising the steps of: forming a nail preform 192, forming an integrated color display 163 as described above, and bonding the lower side 195 of the nail preform 192 to the upper side 168 of the integrated color display 163 as shown in FIG. 6.

[0094] Referring now to FIG. 11, another aspect relates to a digital color-changing object system 620, which includes a client device 130 and a color-changing object 640. The color-changing object 640 may include, for example, brooches, pendants, jewelry, earrings, phone cases, and glasses. The description of these objects is not limiting, as other types of color-changing objects may be used.Although not shown, the digital color-changing object system 620 can also operate using object access codes and a data collection server, as described above for the integrated digital nail system 120.

[0095] Specifically, the color-changing object 640 includes an integrated color display 163, which can be programmed by a user to display a user-selected color. The integrated color display 163 is based on the integrated artificial nail assembly 160 shown in FIG. 1, but with the nail blank 192 and nail interface adapter 194 removed. The user-selected color option is provided to the integrated color display 163 by a client device 130, such that the chipset 502 programs the integrated color display 163 based on the received user-selected color.

[0096] In the above discussion of the integrated artificial nail assembly 160 and the color-changing object 640, the use of the color display 162 is based on electronic paper containing microcapsules. In an alternative embodiment, the electronic paper can be replaced by a digital display. The digital display can be configured, for example, as an LED display. An LED display is a flat panel display that uses an array of light-emitting diodes (LEDs) as pixels for a video display. LED displays allow the display of images and graphics. The brightness of LEDs allows them to be used outdoors and are easily visible in sunlight.

[0097] Many modifications and other embodiments will occur to those skilled in the art from the teachings given in the foregoing description and drawings. Therefore, it should be understood that the foregoing is not limited to the exemplary embodiments, and that modifications and other embodiments are intended to be included within the scope of the appended claims.Instruction Manual Page 10 / 10 15 CN 122070069 A Figure 1 Instruction Manual Figure 1 / 14 Page 16 CN 122070069 A Figure 2A Instruction Manual Figure 2 / 14 Page 17 CN 122070069 A Figure 2B Instruction Manual Figure 3 / 14 Page 18 CN 122070069 A Figure 3A Instruction Manual Figure 4 / 14 Page 19 CN 122070069 A Figure 3B Instruction Manual Figure 5 / 14 Page 20 CN 122070069 A Figure 4 Figure 5A Instruction Manual Figure 6 / 14 Page 21 CN 122070069 A Figure 5B Figure 5C Instruction Manual Figure 7 / 14 Page 22 CN 122070069 A Figure 6 Instruction Manual Figure 8 / 14 Page 23 CN 122070069 A Figure 7A Figure 7B Instruction Manual Figure 9 / 14 Page 24 CN 122070069 A Figure 8A Figure 8B Appendix to the Specification 10 / 14 Page 25 CN 122070069 A Figure 9 Appendix to the Specification 11 / 14 Page 26 CN 122070069 A Figure 10A Appendix to the Specification 12 / 14 Page 27 CN 122070069 A Figure 10B Appendix to the Specification 13 / 14 Page 28 CN 122070069 A Figure 11 Appendix to the Specification 14 / 14 Page 29 CN 122070069 A.
