[0050] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0052] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. Similarly, "including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0053] As used herein, "parallel" and "perpendicular" include the described situation and the situation similar to the described situation, and the range of the similar situation is within the acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the error associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°.

[0054] It will be understood that when a layer or an element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present between the layer or element and the other layer or substrate.

[0055] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are conceivable. Therefore, the exemplary embodiments should not be interpreted as being limited to the shapes of the regions shown herein, but include deviations in shape due to, for example, manufacturing. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shapes of regions of the device, and are not intended to limit the scope of the exemplary embodiments.

[0056] Among the related technologies, OLED beauty masks have received widespread attention in the field of phototherapy beauty due to their advantages such as having a variety of different beauty functions and being flexible and easy to carry.

[0057] For example, in some embodiments, the OLED beauty mask can emit red light with a wavelength in the range of 620-700nm, which has the effects of inhibiting inflammation and promoting collagen production. In other embodiments, the OLED beauty mask can emit blue light with a wavelength in the range of 450-495nm, which has the effects of shrinking pores, improving acne and blackheads. In other embodiments, the OLED beauty mask can emit yellow light with a wavelength in the range of 570-590nm, which has the effects of brightening and rejuvenating the skin, reducing skin inflammation, etc. In other embodiments, the OLED beauty mask can emit green light with a wavelength in the range of 495-570nm, which has the effects of whitening the skin and controlling oil secretion, etc.

[0058] At present, an OLED beauty mask generally only emits light of a single wavelength in a fixed band, such as red light. Therefore, an OLED beauty mask cannot fully exert the beauty advantages of different colored lights, limiting the scope of use of an OLED beauty mask. Producing multiple OLED beauty masks that emit different colored lights will greatly increase production costs.

[0059] Furthermore, users may have different beauty problems in different facial areas, and using the same color light to beautify the entire face will result in a waste of light in facial areas that do not need the light, and may even cause damage to the skin in facial areas that do not need the light.

[0060] In order to at least alleviate or solve one of the above-mentioned technical problems, the present disclosure provides a mask and a beauty device.

[0061] Figure 1 It is a schematic diagram of the planar structure of the mask in some embodiments of the present disclosure. Figure 2 is a schematic diagram of the cross-sectional structure of the mask in some embodiments of the present disclosure, specifically along Figure 1Schematic diagram of the cross-sectional structure cut along the middle cutting line BB'.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the present disclosure provides a mask 10 having a facial fitting area AA. The mask 10 comprises: a light-emitting sub-mask 11 and a functional sub-mask 12.

[0063] Figure 3 Schematic diagram of the cross-sectional structure of the mask in the facial fitting area AA in some embodiments of the present disclosure. Figure 4 Schematic diagram of the cross-sectional structure of the mask in the facial fitting area AA in other embodiments of the present disclosure.

[0064] Among them, Figure 3 and Figure 4 As shown, the light-emitting sub-mask 11 includes a light-emitting layer 113 located in the facial fitting area AA. The light-emitting layer 113 is used to emit light of M colors, where M is a positive integer.

[0065] The functional sub-mask 12 is located at the light-emitting side of the light-emitting sub-mask 11. The functional sub-mask 12 includes an optical functional layer 122 opposite to the light-emitting layer 113. The optical functional layer 122 is used to receive the light emitted by the light-emitting sub-mask 11 and emit light of N colors, where N is a positive integer less than or equal to M. The light emitted by the optical functional layer 122 is different in color from the light emitted by at least one light-emitting layer 113.

[0066] For example, in one example, M=2, that is, the light emitting layer 113 emits two colors of light, specifically red light and green light. After receiving the red light and the green light, the optical functional layer 122 can absorb the red light and emit green light at the same time. At this time, the emitted green light is the light emitted by the optical functional layer 122, that is, N=1. Obviously, the green light emitted by the optical functional layer 122 is different in color from the red light emitted by the light emitting layer 113. That is, in this example, the light emitted by the optical functional layer 122 is different in color from the light emitted by one of the light emitting layers 113.

[0067] In another example, M>2, for example, the light emitted by the light-emitting layer 113 is white light, and the white light includes light of M colors, for example, specifically including light of multiple colors such as red light, blue light and green light. After receiving the light of these M colors, the optical functional layer 122 can absorb light other than blue light, for example, absorb red light and green light, and emit blue light at the same time. At this time, the emitted blue light is the light emitted by the optical functional layer 122, that is, N=1. Obviously, the blue light emitted by the optical functional layer 122 is different from the colors of red light and green light in the white light emitted by the light-emitting layer 113. That is, in this example, the light emitted by the optical functional layer 122 is different in color from the light emitted by the M-1 light-emitting layers 113.

[0068] In another example, M=1, that is, the light emitting layer 113 emits light of one color. For example, the light emitted by the light emitting layer 113 is blue light. After receiving the blue light, the optical functional layer 122 can absorb the blue light and emit red light at the same time. At this time, the emitted red light is the light emitted by the optical functional layer 122, that is, N=1. Obviously, the red light emitted by the optical functional layer 122 is different from the blue light emitted by the light emitting layer 113. That is, in this example, the light emitted by the optical functional layer 122 is different from the color of the light emitted by the light emitting layer 113.

[0069] In another example, M=3, that is, the light emitting layer 113 emits three colors of light, including blue light, red light and green light, and the optical functional layer 122 can absorb blue light and emit red light and green light at the same time. The red light and green light at this time are the light emitted by the optical functional layer 122, that is, N=2. Obviously, the red light emitted by the optical functional layer 122 is different in color from the green light and blue light emitted by the light emitting layer 113, and the green light emitted by the optical functional layer 122 is different in color from the red light and blue light emitted by the light emitting layer 113. That is, in this example, each light emitted by the optical functional layer 122 is different in color from the light emitted by the two light emitting layers 113.

[0070] In the embodiment of the present disclosure, a functional sub-mask 12 is arranged on the light-emitting side of the light-emitting sub-mask 11, and the color of light emitted by the light-emitting layer 113 in the light-emitting sub-mask 11 can be changed through the optical functional layer 122 in the functional sub-mask 12. Specifically, the color of light emitted by the optical functional layer 122 is different from the color of at least one of the lights emitted by the light-emitting layer 113, so that the mask 10 can emit light of multiple different colors, thereby meeting the user's beauty needs for different colors of light.

[0071] In some embodiments, the display sub-mask 10 and the functional sub-mask 12 are detachably connected.

[0072] Optionally, the display sub-mask 10 and the functional sub-mask 12 can be detachably connected by means of connectors such as snap buttons, magnetic buttons, Velcro, hook and loop fasteners, and Velcro.

[0073] Figure 5 It is a schematic diagram of the planar structure of a sub-mask in some embodiments of the present disclosure. Figure 6 It is a schematic diagram of the planar structure of the functional sub-mask in some embodiments of the present disclosure.

[0074] Specifically, Figure 5 As shown, the edge area NA of the sub-mask 11 is provided with a first connecting member 40, such as Figure 6 As shown, the edge area NA of the functional sub-mask 12 is provided with a second connecting piece 50 .

[0075] Optionally, the first connecting member 40 is located on a side of the display sub-mask 11 close to the functional sub-mask 12, and the second connecting member 50 is located on a side of the functional sub-mask 12 close to the display sub-mask 11, and the first connecting member 40 and the second connecting member 50 are arranged opposite to each other. The first connecting member 40 and the second connecting member 50 can be detachably connected by means of snap connection, magnetic attraction, bonding, etc.

[0076] In the disclosed embodiment, the display sub-mask 10 and the functional sub-mask 12 are detachably connected. When the display sub-mask 10 and the functional sub-mask 12 are in a detached state, the display sub-mask 10 can be used for phototherapy beauty. When the display sub-mask 10 and the functional sub-mask 12 are in a connected state, the mask 10 as a whole can be used for phototherapy beauty.

[0077] Furthermore, the same display sub-mask 10 in the embodiment of the present disclosure can be used in combination with different functional sub-masks 12, and the same functional sub-mask 12 in the embodiment of the present disclosure can also be used in combination with different display sub-masks 10. Therefore, the embodiment of the present disclosure can achieve different matching combinations through the display sub-mask 10 and the functional sub-mask 12, thereby meeting the user's needs for various beauty color lights.

[0078] In the embodiment of the present disclosure, the description of the components of the mask 10 and the positional relationship between the film layers is based on the description that the display sub-mask 10 and the functional sub-mask 12 are in a connected state.

[0079] Alternatively, if Figure 3 and Figure 4 As shown, the display sub-mask 10 further includes a first electrode located at the light-emitting layer 113 away from the functional sub-mask 12, a second electrode located at the light-emitting layer 113 close to the functional sub-mask 12, and a driving circuit layer 112 located at the first electrode away from the functional sub-mask 12. (The first electrode and the second electrode are not shown in the figure)

[0080] The light-emitting layer 113 can emit light under the driving action of the voltage between the first electrode and the second electrode.

[0081] Optionally, the driving circuit layer 112 includes a thin film transistor, which is electrically connected to the first electrode and is used to control the light emitting layer 113 to emit light.

[0082] Alternatively, if Figure 3 and Figure 4 As shown, the display sub-mask 10 further includes a first substrate 111 located on the side of the driving circuit layer 112 away from the functional sub-mask 12 and a second substrate 115 located on the side of the second electrode away from the functional sub-mask 12. The first substrate 111 is a non-transparent substrate, and the second substrate 115 is a transparent substrate. That is, the light emitted by the light-emitting layer 113 can be emitted from the side of the second substrate 115.

[0083] Alternatively, if Figure 3 and Figure 4 As shown, a first encapsulation layer 114 is further disposed between the second substrate 115 and the second electrode.

[0084] Alternatively, if Figure 3 and Figure 4 As shown, the functional sub-mask 12 further includes a third substrate 121 located on the side of the optical functional layer 122 close to the light-emitting sub-mask 11 and a fourth substrate 124 located on the side of the optical functional layer 122 away from the light-emitting sub-mask 11. Both the third substrate 121 and the fourth substrate 124 are transparent substrates.

[0085] Alternatively, if Figure 3 and Figure 4 As shown, the functional sub-mask 12 further includes a second encapsulation layer 123 located between the optical functional layer 122 and the fourth substrate 124 , and / or a third encapsulation layer located between the optical functional layer 122 and the third substrate 121 . Figure 3 and Figure 4 The illustrated embodiment specifically shows the case where the functional sub-mask 12 includes the second encapsulation layer 123 .

[0086] In some embodiments, the M colors of light include the first color light and the second color light, and the N colors of light include the second color light.

[0087] like Figure 3 As shown, the optical function layer 122 includes a photoelectric conversion sublayer 1222 , and the photoelectric conversion sublayer 1222 includes a transparent substrate and a photoelectric conversion material distributed in the transparent substrate.

[0088] The photoelectric conversion material can absorb the first color light and convert the first color light into electrical energy, and the transparent substrate can transmit the second color light.

[0089] In the embodiment of the present disclosure, the light-emitting layer 113 emits a first color light and a second color light, the photoelectric conversion material in the optical function layer 122 absorbs the first color light and converts the first color light into electrical energy, and at the same time, the transparent substrate in the optical function layer 122 emits the second color light, thereby providing beauty to the user through the second color light.

[0090] Optionally, the colors of the first color light and the second color light may be different.

[0091] Optionally, the first color light may have one color or multiple colors.

[0092] For example, in one example, the first color light is red light, and the second color light is green light, and the mask 10 in this example emits green light. Therefore, the mask 10 can be provided to users who need green light for beauty treatment.

[0093] In another example, the first color light includes red light and green light, and the second color light is blue light. The mask 10 in this example emits blue light. Therefore, the mask 10 can be provided to users who need blue light for beauty treatment.

[0094] Optionally, the second color light may be of one color or of multiple colors.

[0095] For example, in one example, the first color light is green light, and the second color light is red light, and the mask 10 in this example emits red light. Therefore, the mask 10 can be provided to users who need red light for beauty treatment.

[0096] In another example, the first color light is blue light, and the second color light includes red light and green light, then the mask 10 in this example emits composite light including red light and green light, and the composite light may be yellow light, for example. Therefore, the mask 10 in the embodiment of the present disclosure can be provided to users who need composite light for beauty treatment.

[0097] Optionally, the first color light and the second color light have similar or identical colors but different wavelengths.

[0098] For example, in one example, the first color light is red light with a wavelength in the range of 700-720nm, and the second color light is also red light with a wavelength in the range of 620-700nm, that is, in this example, the photoelectric conversion material can absorb red light with a wavelength in the range of 700-720nm, and the light-transmitting substrate transmits red light with a wavelength in the range of 620-700nm. Then, the mask 10 in this example can emit red light with a wavelength in the range of 620-700nm. Therefore, the mask 10 can be provided to users who need red light with a wavelength in the range of 620-700nm for beauty treatment.

[0099] In another example, the first color light is red light with a wavelength in the range of 620-720nm, and the second color light includes red light with a wavelength in the range of 600-620nm, and includes red light with a wavelength in the range of 700-720nm, that is, the embodiment of the present disclosure can further purify the color of the first color light emitted by the light-emitting layer 113, so that the color of the second color light emitted by the optical functional layer 122 is purer, thereby ensuring the cosmetic effect of the second color light.

[0100] To sum up, in the embodiment of the present disclosure, the first color light is absorbed by the photoelectric conversion material, and the second color light is transmitted through the transparent substrate, so that the mask 10 finally emits the second color light, and the color, wavelength and other parameters of the second color light can be set according to the material of the light-emitting layer 113 and the photoelectric conversion material, etc., as needed. Therefore, the mask 10 in the embodiment of the present disclosure can meet the user's needs for various beauty color lights.

[0101] In some embodiments, the photoelectric conversion material includes an electron donor and an electron acceptor.

[0102] For example, in one example, if the beauty mask 10 is required to emit red light, when selecting the photoelectric conversion material, an electron donor and an electron acceptor that have no absorption in the wavelength range of 620-700 nm can be selected.

[0103] In another example, if a green-light-emitting beauty mask 10 is desired, when selecting the photoelectric conversion material, an electron donor and an electron acceptor that have no absorption in the wavelength range of 495-570 nm may be selected.

[0104] Therefore, the embodiment of the present disclosure can realize that the mask 10 emits different colored lights by selecting different electron donors and electron acceptors, thereby meeting the user's needs for different cosmetic colored lights.

[0105] Optionally, the electron donor may be, for example, P3HT (3-hexyl substituted polythiophene), the electron acceptor may be, for example, PCBM (phenyl-C61-butyric acid methyl ester), and the material of the transparent substrate may include, for example, at least one of chlorobenzene (CB) and chloroform (CF).

[0106] The disclosed embodiment adjusts the concentration of P3HT and PCBM in the transparent substrate so that the electron donor-acceptor material formed by P3HT and PCBM can absorb light of a certain wavelength band and convert it into electrical energy. Correspondingly, the light not absorbed by the electron donor-acceptor material formed by P3HT and PCBM can be transmitted through the transparent substrate.

[0107] For example, in one example, the concentration of P3HT and PCBM in the transparent substrate is 1:3. At this time, the electron donor-acceptor material formed by P3HT and PCBM absorbs light with a wavelength in the range of 650-700nm weakly, but absorbs light with a wavelength in the range of 300-620nm strongly. At this time, the wavelength of the colored light emitted by the beauty mask 10 is in the range of 650-700nm, that is, red light.

[0108] The disclosed embodiment can adjust the concentration ratio of P3HT and PCBM in the transparent substrate so that the electron donor-acceptor material formed by P3HT and PCBM absorbs and filters the light emitted by the light-emitting layer 113, thereby achieving the beauty mask 10 emitting light of corresponding colors.

[0109] Figure 7 It is a schematic diagram of the planar structure of the light-emitting sub-mask in some embodiments of the present disclosure. Figure 8 It is a schematic diagram of the planar structure of the functional sub-mask in some embodiments of the present disclosure.

[0110] In some embodiments, Figure 1 As shown, the mask 10 also has an edge region NA, which is located at the periphery of the face fitting region AA.

[0111] The light-emitting sub-mask 11 includes a first conductive layer (not shown in the figure) located in the edge area NA. Figure 7 As shown, the light-emitting sub-mask 11 further includes a first connection terminal 101 and a second connection terminal 102 electrically connected to the first conductive layer.

[0114] For example, in one example, the first connection terminal 101 is detachably electrically connected to the third connection terminal 201. In the embodiment of the present disclosure, the second conductive layer transmits the electric energy generated by the photoelectric conversion sublayer 1222 to the third connection terminal 201. After the third connection terminal 201 is electrically connected to the first connection terminal 101, the third connection terminal 201 transmits the electric energy to the first connection terminal 101, the first connection terminal 101 transmits the electric energy to the first conductive layer, and the first conductive layer transmits the electric energy to the second connection terminal 102.

[0115] That is, the electrical connection between the first connection terminal 101 and the third connection terminal 201 can realize the transmission of electric energy to the second connection terminal 102 through the third connection terminal 201. In this case, the second connection terminal 102 can be electrically connected to the external power source 21, for example, it can be electrically connected to the battery, and the second connection terminal 102 can realize the transmission of electric energy to the battery for storage.

[0120] Optionally, the first connecting terminal 101 is located on a side of the light-emitting sub-mask 11 close to the functional sub-mask 12, the third connecting terminal 201 is located on a side of the functional sub-mask 12 close to the light-emitting sub-mask 11, and the first connecting terminal 101 and the third connecting terminal 201 are both located in the edge area NA and are arranged opposite to each other. At this time, the first connecting terminal 101 and the third connecting terminal 201 can be directly buckled.

[0121] Optionally, the first connection terminal 101 is electrically connected to the first light-emitting layer 113 via a second flexible member, and / or the second connection terminal 102 is electrically connected to the first light-emitting layer 113 via a third flexible member.

[0122] Optionally, the third connection terminal 201 is electrically connected to the photoelectric conversion sublayer 1222 through a fourth flexible member.

[0123] In the embodiment of the present disclosure, when the optical functional layer 122 has a photoelectric conversion function, by providing a first connection terminal 101, a second connection terminal 102 and a third connection terminal 201, it is convenient to effectively extract and store the electric energy generated by the photoelectric conversion sublayer 1222, thereby improving resource utilization.

[0124] Moreover, in the embodiment of the present disclosure, there are multiple ways of electrically connecting the first connection terminal 101, the second connection terminal 102 and the first light-emitting layer 113, the way of electrically connecting the third connection terminal 201 and the photoelectric conversion sublayer 1222, and the ways of connecting the first connection terminal 101 and the third connection terminal 201, which can be selected according to actual needs, thereby increasing the usability of the light-emitting sub-mask 11 and the functional sub-mask 12 in the embodiment of the present disclosure.

[0125] In some embodiments, Figure 3 As shown, the optical functional layer 122 also includes a transparent conductive sublayer 1221 stacked with the photoelectric conversion sublayer 1222. The transparent conductive sublayer 1221 is electrically connected to the photoelectric conversion sublayer 1222 and the third connection terminal 201 respectively. The transparent conductive sublayer 1221 is used to transmit the electric energy converted by the photoelectric conversion sublayer 1222 to the third connection terminal 201.

[0126] The embodiment of the present disclosure can effectively conduct the electric energy generated by the photoelectric conversion sublayer 1222 to the third connection terminal 201 by providing a transparent conductive sublayer 1221 stacked with the photoelectric conversion sublayer 1222, so as to facilitate the subsequent use of the electric energy and avoid the waste of electric energy.

[0127] Optionally, the transparent conductive sublayer 1221 covers the photoelectric conversion sublayer 1222 .

[0128] In the disclosed embodiment, the transparent conductive sublayer 1221 covering the photoelectric conversion sublayer 1222 can further ensure that the electric energy generated by the photoelectric conversion sublayer 1222 is transmitted in time, avoiding waste of electric energy and preventing leakage of electric energy from affecting the functional sub-mask 12 and the user.

[0129] Optionally, the transparent conductive sub-layer 1221 is located on a side of the photoelectric conversion sub-layer 1222 close to the light-emitting sub-mask 11 .

[0130] In some embodiments, the M colors include a third color and a fourth color. The N second colors include a fourth color. The optical function layer 122 includes a filter material that absorbs the third color and transmits the fourth color. The third color and the fourth color are different in color.

[0131] Optionally, the third color light may be one or more.

[0132] For example, in one example, M colors of light are mixed into white light. Among them, the third color light includes colors other than red light, such as green light and blue light. The fourth color light is red light. That is, the filter material absorbs colors other than red light and transmits red light. In the mask 10 in this example, the mask 10 emits red light, which can be provided to users who need red light for beauty treatment.

[0133] In another example, the M color lights include red light and green light, the third color light includes red light, and the fourth color light is green light. That is, the filter material absorbs red light and transmits green light, so in the mask 10 in this example, the mask 10 emits green light, which can be provided to users who need green light.

[0134] It is understandable that the optical function layer 122 in the embodiment of the present disclosure is a filter. When the mask 10 is required to emit red light, the optical function layer 122 is a red filter, that is, it filters out light other than red light.

[0135] Therefore, in the embodiment of the present disclosure, the light emitting layer 113 emits a plurality of third color lights of different colors, and a color filter is configured as the optical function layer 122, so that the color of the fourth color light emitted by the optical function layer 122 can be controlled. Therefore, in the embodiment of the present disclosure, different masks 10 can emit different color lights through the color filter, thereby meeting the different needs of users for beauty color lights.

[0136] In some embodiments, the M colors include a fifth color. The N second colors include a sixth color. The optical function layer 122 includes a light conversion material that can absorb the fifth color and convert the fifth color into a sixth color. The fifth color and the sixth color are different in color.

[0137] Optionally, the fifth color light may be of one color or of multiple colors.

[0138] Optionally, the sixth color light may be of one color or of multiple colors.

[0139] For example, in one example, the fifth color light includes blue light, and the sixth color light may be at least one of red light, green light, and yellow light.

[0140] The embodiment of the present disclosure changes the color of the first color light emitted by the light-emitting layer 113 through the light conversion material, thereby achieving control over the color of the color light emitted by the mask 10, thereby meeting the different needs of users for beauty color light.

[0141] In some embodiments, the light conversion material includes at least one of a fluorescent material and a quantum dot (QD) material.

[0142] Optionally, the fluorescent material may include at least one of red fluorescent powder, green fluorescent powder, and yellow fluorescent powder, wherein, for example, the red fluorescent material can emit red light under the excitation of blue light.

[0143] Alternatively, the quantum dot material may include an inorganic quantum dot material, such as copper indium sulfide (CuInS2) quantum dot material that can emit red light under the excitation of blue light.

[0144] The embodiment of the present disclosure can change the color of the light emitted by the light-emitting layer 113 by setting corresponding fluorescent materials or quantum dot materials in the optical functional layer 122, thereby controlling the color of the light emitted by the mask 10 to meet the different needs of users for beauty color light.

The optical function layer 122 includes an optical function portion located in the bonding sub-region A1. The optical function portion is used to receive the light emitted by the light-emitting portion and emit light of N colors.

[0149] It is understandable that the optical function parts correspond to the light emitting parts one by one, and the light emitted by the optical function parts is different in color from the light emitted by at least one corresponding light emitting part.

[0150] Among them, the M colors of light emitted by at least two light-emitting parts are different, and / or the N colors of light emitted by at least two optical functional parts are different.

[0151] The M colors of light rays are different, which may mean that at least one of the light rays has a different color, or the number of color types of the light rays is different, that is, the value of M is different. The N colors of light rays are different, which may mean that at least one of the light rays has a different color, or the number of color types of the light rays is different, that is, the value of N is different.

[0152] For example, in one example, the number and color of the M kinds of light emitted by the light-emitting portion corresponding to the forehead and the light-emitting portion corresponding to the cheek are the same, for example, both include red light and green light. The color of the light emitted by the optical functional portion corresponding to the forehead and the optical functional portion corresponding to the cheek is different, for example, the optical functional portion corresponding to the forehead emits green light, and the optical functional portion corresponding to the cheek emits red light.

[0153] In another example, the light emitting portion corresponding to the forehead and the light emitting portion corresponding to the cheek emit different colors and types of light, for example, the light emitting portion corresponding to the forehead emits blue light, and the light emitting portion corresponding to the cheek emits white light. The optical function portion corresponding to the forehead and the optical function portion corresponding to the cheek emit different colors of light, for example, the optical function portion corresponding to the forehead emits green light, and the optical function portion corresponding to the cheek emits yellow light.

[0154] In the embodiment of the present disclosure, the number and color of the types of light emitted by the light-emitting portion, as well as the number and color of the types of light emitted by the optical functional portion, can be specifically set according to actual conditions, and the embodiment of the present disclosure will not list them one by one.

[0155] In the embodiment of the present disclosure, the number of fitting sub-areas A1 and the division of specific positions can be designed differently for different masks 10 according to actual needs, so that different areas of the face can be treated with independent light therapy. Furthermore, the needs of different areas of the face for beauty color light can be met by combining the materials of the light-emitting part and the corresponding optical functional part.

[0156] Furthermore, designing a plurality of face fitting sub-areas A1 can also make the mask 10 fit the face more closely, thereby improving the phototherapy beauty effect of the colored light.

[0158] Optionally, the cosmetic device of the present disclosure further comprises a wearable structure, which is connected to the edge area NA of the mask 10. The wearable structure is used to fix the mask 10 to prevent the mask 10 from slipping off during the phototherapy process after being fitted to the face.

[0159] For example, in one example, the end of the wearable structure away from the mask 10 may be provided with a ring-shaped connector, the ring-shaped connector may be connected to a strap, and the strap may be tied behind the head to fix the mask 10.

[0160] For instance, in another example, the wearable structure may be a helmet-type wearable structure.

[0172] In some embodiments, Fig.12 As shown, the light-emitting sub-mask 11 further includes a fourth connection terminal 103 electrically connected to the third conductive layer. The flexible conductive member 30 includes a first transmission line and a second transmission line.

[0173] Among them, one end of the first transmission line is electrically connected to the first connection terminal 101 and the other of the second connection terminals 102, and the other end of the first transmission line is electrically connected to the external power supply 21. The first transmission line is used to transmit the electrical energy output by the photoelectric conversion sublayer 1222 to the external power supply 21 for storage.

Optionally, the driving circuit board 22 is connected between the external power supply 21 and the fourth connection terminal 103.
