Description
Technical Field
The invention relates to a cosmetic shell with a light source. And more particularly, to a cosmetic case integrating an OLED light source and a cosmetic using the same.
Background
The pursuit of beauty for human beings has been long, related records of using cosmetics have been available for thousands of years, and in modern society, cosmetics have become very popular as consumer products, and with the continuous improvement of science and technology, people have not only the demand of beauty but also many functional appeal for cosmetics.
Lipstick/lip balm is one of the most basic types of cosmetics. Generally speaking, the lipstick/lip stick needs to be applied to a mirror, so that the style of the lipstick/lip stick with a mirror begins to appear on the market, for example, a lip stick cover of the Jiaolan in FIG. 1 can be folded, and the inner part is a mirror surface (https:// www.guerlain.com.cn/zhen-cai-bao-shi-chun-gao-2018. html); or a mirror (https:// www.xiaohongshu.com/discovery/item/57e945b414de412a33d7cd81) is inlaid in other parts of the cover body. The lipstick with the mirror is very practical, and solves the requirement that busy modern people need multifunctional products, but the lipstick can be only used under the condition that the ambient light is bright enough. In order to solve this problem, some products have a mirror surface coated on one side of the cover body, and 1-2 LED beads are integrated into the lipstick cover (https:// detail.1688.com/offer/549177848782. htmlpsm ═ a 261b.2187593.0.0.200d13cdeW5NO), or as shown in FIG. 2, illuminated LED beads are integrated on the lipstick tube to solve the illumination problem of dark field makeup. However, such combination is not practical because, firstly, the LED lamp beads are all point light sources, and the emitted light is very dazzling when directly irradiating the human face, which may affect the vision; secondly, the existing design cannot be compatible with the use of illumination and a mirror, for example, when the lipstick in fig. 2 is used, the light source moves along with the movement of the lipstick, and the use is influenced (https:// www.youtube.com/watchv ═ Rec190vV4 SY); finally, LED lamp pearl and mirror surface occupation space simultaneously can make the lipstick pipe must have certain volume just can make the mirror surface big enough, perhaps the pipe shaft is big enough in order to hold LED lamp pearl module, and this is contradictory with the requirement that people carried to make up the product lightly again. Similarly, many other cosmetic products suffer from the above problems, particularly small, portable cosmetic products.
The flexible OLED display has the advantages of being light and thin in size, low in power consumption, flexible, good in flexibility and the like, and is generally applied to mobile electronic devices such as mobile phones and tablet computers. FIG. 3 shows a conceptual flexible OLED display screen, which can be rolled into a pen and can be pulled open to display a full screen (https:// rolled. com/rolled-marks/flexible-future/attachment/pen-with-rolled-display-variance-locations /) when necessary. However, due to the complexity of the backplane circuitry and the integrated optical polarizer in front of the screen, such a display screen is not useable as a mirror, and is typically black with a slight reflection effect in the off state, as can be seen in the comparative LG rollable television photographs shown in FIGS. 4a (TV on state) and 4b (TV off state) (https:// www.lifewire.com/what-is-a-roll-up-tv-4686358). The OLED light-emitting panel used in the invention is provided with a reflective anode or cathode, and is directly prepared on a substrate in a large-area mode without a backboard circuit or a polaroid, so that the mirror effect is obvious.
It is not uncommon to combine illumination with a mirror using the mirror effect of the OLED illumination panel when turned off. A mirror for realizing a lighting function by integrating a plurality of OLED light-emitting panels is disclosed in, for example, patent CN 202515153U. For another example, FIG. 5 shows a Philips Living Shapes sensing OLED mirror (https:// www.youtube.com/watchv ═ 88 BvvggjsJvk) that integrates an array of OLED light emitting panels in a mirror (as shown in FIG. 5 a). The above examples are all implemented by a series of sensors and/or control switches that selectively turn on or off some OLED light emitting panels to simultaneously achieve the lighting function and the mirror function, e.g. the surrounding OLED panels may be illuminated with a mirror effect in between (as shown in fig. 5 b). However, in the above example, the OLED light-emitting panels are arranged in a plane, and the combination of illumination and mirror can be realized only in the same plane, and the light emitted by each OLED light-emitting panel is in the same direction. When the OLED light-emitting panel is used as a mirror, the panel and the mirror are integrated into a plane, so that the OLED light-emitting panel is suitable for being used in a large-area fixed place, but the volume and the weight are inevitably increased due to the integration of the mirror and the requirement of a plurality of OLED light-emitting panels, and the OLED light-emitting panel is not suitable for being applied to portable products. In the invention, any non-planar included angle or radian can be formed among the plurality of OLED light-emitting panels, and each OLED light-emitting panel can be independently driven; an OLED light-emitting panel can also be rolled folded with a plurality of independently controllable OLED devices. The invention can realize that the angle of the light source can be adjusted at will when the mirror is used so as to achieve the best lighting effect, and meanwhile, the volume of the mirror surface can be reduced through operations such as folding, curling and the like, thereby being particularly suitable for being used as a mobile portable product.
Based on the practical problems, the invention provides a cosmetic shell integrating an OLED light source and a cosmetic using the cosmetic shell.

A typical single layer OLED device is shown in figure 6 a. The OLED device 100 includes, among other things, an anode layer 101, a Hole Injection Layer (HIL)102, a Hole Transport Layer (HTL)103, an Electron Blocking Layer (EBL)104, an emission layer (EML)105, a Hole Blocking Layer (HBL)106, an Electron Transport Layer (ETL)107, an Electron Injection Layer (EIL)108, and a cathode layer 109. The light-emitting layer 105 typically further comprises at least one host material and at least one light-emitting material, and the electron-blocking layer 104 and the hole-blocking layer 106 are optional layers. The hole injection layer 102 may be a single layer of material, such as the commonly used HAT-CN; the hole injection layer 102 may also be a hole transport material doped with a certain proportion of a p-type conductivity dopant material. A single layer white OLED device may also include multiple light emitting layers, such as dual light emitting layer OLED device 110 shown in fig. 6b, which includes light emitting layers 105a and 105 b. In general, when white light is produced, it is possible to realize a white light by superimposing a blue light-emitting layer and a yellow light-emitting layer. Accordingly, the OLED device 110 as shown in fig. 6b may comprise one yellow light emitting layer 105a and one blue light emitting layer 105 b. The yellow light emitting layer 105a can be realized by doping a yellow light host material with a yellow light emitting material, or can be realized by doping a green light emitting material and a red light emitting material with a host material; similarly, the blue light emitting layer 105b may be implemented by doping a blue light emitting material with a blue host material. Note that although OLED device 110 has two light emitting layers, it is still considered a single layer device because it has only one set of transport material systems. It is of course also possible to prepare a single-layer device with three light-emitting layers on top of the OLED device 110, for example by successively superimposing a red, a green and a blue light-emitting layer. Techniques for producing white light using single layer device structures are well known to those skilled in the art and will not be described in detail herein.
The white OLED device can also be implemented in a stacked structure, and a structural diagram of a stacked OLED device 200 is shown in fig. 6c, for example, and includes a first light emitting unit 201 and a second light emitting unit 202, wherein the light emitting units 201 and 202 include the same organic layers as in the OLED device 100, and the two light emitting units are connected by a charge generation layer 111, and an anode 101 and a cathode 109 are respectively disposed at the bottom and the top of the stacked OLED device 200. The charge generation layer 111 may further include an n-type material layer and a p-type material layer to conduct electrons and holes, respectively. The charge generation layer may further comprise a buffer layer material, and reference may be made to patent application CN 2019109871570. The stacked OLED device shown in fig. 6c is a double-layer structure, and if white light is to be prepared, a blue light emitting unit and a yellow light emitting unit can be stacked, for example, the light emitting unit 201 is a yellow light emitting unit, the light emitting layer 105 has a yellow light host material doped with a yellow light emitting material, and the light emitting unit 202 is a blue light emitting unit, which has a blue light host material doped with a blue light emitting material. In another embodiment, the yellow light emitting unit may also adopt an organic layer structure of the dual light emitting layer OLED device 110 as shown in fig. 6b, i.e., a structure in which one red light emitting layer and one green light emitting layer are stacked. Similarly, the yellow light-emitting unit can be further split into a red light-emitting unit and a green light-emitting unit, as shown in the three-layer stacked OLED device 210 in fig. 6d, which includes a first light-emitting unit 201 (red light-emitting unit), a second light-emitting unit 202 (green light-emitting unit), and a third light-emitting unit 203 (blue light-emitting unit), the light-emitting units are connected with each other by charge generation layers 111 and 121, and the anode 101 and the cathode 109 are disposed at two ends of the device. Techniques for producing white light using stacked device structures are well known to those skilled in the art and will not be described in detail herein.
To achieve the mirror effect, one of the anode 101 and the cathode 109 in the above-described OLED device is an electrode layer having a reflective effect. For example, if the OLED device is a bottom emission device, the anode may be transparent or semi-transparent ITO, IZO, etc., and the cathode 109 may be a metal material having high reflectivity, such as aluminum, silver, etc.; if the OLED device is a top-emitting device, the anode 101 can be silver or a material of ITO/silver/ITO combination and the cathode is one of Yb, MgAg, or a combination thereof, which is translucent. In some embodiments, the anode 101 and the cathode 109 of the OLED device may be transparent or translucent, and the substrate or the encapsulation layer used in the OLED light-emitting panel is made of a material with a reflective effect, for example, a flexible OLED light-emitting panel may use a metal film as the substrate, and such a substrate has a reflective effect. In addition, an additional reflective surface can be used as a mirror surface outside the OLED light-emitting panel.
Cross-sectional views of an OLED light-emitting panel are shown in fig. 7a-7 d. The OLED light emitting panel 300 includes a substrate 301, an OLED device 310, a pair of contact electrodes 303 electrically connected to the OLED device 310, a flexible encapsulating layer 302 exposing the contact electrodes 303, and a bonding structure 304 connecting the pair of contact electrodes 303 to an external driving circuit. The substrate 301 may be hard glass or ultra-thin glass (generally having a thickness of 200 μm or less), or may be flexible, including but not limited to ultra-thin flexible glass, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), Polyimide (PI), and the like. In particular, the substrate 301 may be a material (e.g., a polyimide-based material) that is coated on a supporting substrate in the form of a solution in advance, cured, and planarized for device fabrication. After the device is prepared, the device is peeled off from the supporting base plate by using a laser and is transferred to other flexible substrates according to requirements. OLED device 310 can be a bottom emitting device or a top emitting device, with a top emitting device being preferred because of its higher light emitting efficiency. OLED device 310 can be a single layer structure or a stacked layer structure, with a stacked layer structure being preferred because the lifetime of the stacked device is longer at the same luminance and because the film layer is thicker to improve the production yield. The organic material in OLED device 310 may be formed by evaporation in a vacuum chamber by thermal evaporation, or may be formed partially or even entirely using a solution process, including but not limited to ink jet printing (ink jet printing), spin coating, organic vapor spray printing (OVJP), and the like. The flexible encapsulation layer 302 may be ultra-thin glass adhered to the device by UV curable adhesive, preferably a thin film encapsulation layer, with a thickness of usually more than 10 μm, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, and is formed by PECVD, ALD, printing, spin coating, etc. The contact electrode 303 may comprise at least one anode contact and one cathode contact. A front cover film 305 may be added to the above-described OLED light-emitting panel as shown in fig. 7 b. The front cover film 305 may be a Flexible Printed Circuit (FPC) board on which a pre-designed circuit is printed and electrically connected to the OLED device 310 through the adhesive structure 304. In another alternative, the adhesive structure 304 may be an FPC frame and the front cover film 305 may be a sheet of plastic film to provide mechanical support. A specific description of the use of an FPC board to drive an OLED light-emitting panel can be found in chinese patent application CN201810572632.3, which is incorporated by reference in its entirety and is not within the scope of coverage of this application. The front cover film 305 may also include a light extraction layer. When OLED device 310 is top-emitting, front cover film 305 is transparent in the light-emitting area. The front cover film 305 may be a combination of the above. Additional thin film encapsulation layers 306 may be applied to one or both sides of the substrate 301 as shown in fig. 7 c. The front cover film may also be coated with an additional thin film encapsulation layer 306, but is not shown in this figure. In fig. 7d, a back cover film 307 is overlaid onto the substrate 301. The back cover film 307 may be used for mechanical support. When the OLED is a bottom-emitting device, the back cover film 307 may be a light extraction layer and transparent. The back cover film 307 may be a combination of the above. Such an OLED light-emitting panel is one of the basic constituent elements in the present invention.
Since the OLED panel itself can have a specular reflection effect, it can be integrated into a cosmetic housing to function as both a light source and a mirror. In order to ensure that when a part of the OLED light-emitting panel is used as a mirror, other panels can be used as light sources for lighting, which requires that the OLED light-emitting panel module integrated on the cosmetic case can be selectively lighted. There are many ways to achieve this, the first being to design a pixelized layout on one OLED light-emitting panel and then drive each pixel independently, or to group pixels and then drive different groups independently. A pixel here generally refers to a light-emitting area having a millimeter order, i.e., a minimum area of 1mm or more2Preferably 5mm or more2. For example, an OLED light-emitting panel 500 shown in fig. 8a may include an OLED substrate 501 on which a series of OLED devices 502 are patterned, and these devices share the same encapsulation layer 503, in this case, each light-emitting unit is an OLED device, and the whole OLED light-emitting panel is a light source. In this case, the metal wires may be arranged on the panel at the same time of preparing the anode or the cathode for electrically connecting the OLED devices 502, and the method of the metal wires is well known in the art and will not be described herein. By controlling different OLED devices through external electric drive, one part of the devices can be in a lighting state and used as a light source, and the other part of the devices can be in a extinguishing state and used as a mirror. A variation of this is an OLED light emitting panel 510 as shown in fig. 8b comprising an OLED substrate 501, a series of OLED devices 502, but each device enjoys a separate encapsulating layer 513, and preferably the encapsulating layer is a thin film encapsulating layer. At the moment, different OLED devices 502 can be connected through metal wiring and can also be electrically connected through an FPC circuit board, so that the conductivity is greatly improvedAnd the potential for circuit complexity. Also, a single or multiple OLED devices 502 can be independently driven through these electrical connections. In view of the limited volume of the portable cosmetics, the above two modes are particularly suitable for adopting the flexible OLED light-emitting panel, namely, the substrate is flexible, such as ultrathin glass, plastic and the like, and the packaging layer is packaged by a thin film. The flexible OLED light-emitting panel may have a radius of curvature of less than 5cm, preferably less than 3cm, more preferably less than 2 cm. The flexible OLED light-emitting panel may be stored in a tube like a film when it is to be used, and may be unfolded from one end when it is to be used, and a user may selectively light some of the pixels. Alternatively, individual OLED panels may be grouped in a modular array, as shown in fig. 8c, where each panel includes an individual substrate 521, an OLED device 502, and an individual encapsulating layer 513. The benefit of this arrangement is that a non-flexible OLED light emitting panel substrate and/or a non-flexible encapsulation layer may be selected. The independent OLED light-emitting panels can be cut from the same motherboard or can be reassembled by selecting devices with different structures from different motherboards. The method has the advantages that the device can be screened, and the yield is improved. The independent light-emitting panel shown in fig. 8c can be arranged and combined through FPC or front and back cover films, etc. to form a lattice physically connected with each other as required, and it is specifically referred to the method disclosed in CN208750423U and is not in the scope of the present invention. Also, the panels may be independently controlled to apply different operating currents.

The electric drive and the electrical connections can be integrated in the cosmetics housing by design.
Fig. 9a shows a schematic view of a lipstick 600 with an OLED light source, which comprises a cap 610 and a base 620. As shown in fig. 9b, the socket 620 further comprises a lip paste 621 and a socket housing 622; here, the tube cap 610 and the tube base case 622 are both a case of the lipstick 600, i.e., a cosmetic case. The tube cover 610 may be designed in a flip-over mode and further includes tube cover housing portions 611 and 612. The tube cover housing portion 611 may serve as a physical support and may also integrate light sources, including OLEDs, LEDs, etc. Another tube cover housing portion 612 may integrate an OLED light emitting panel and a mirror. The tube cover housing portion 612 can be further divided into multiple regions 6121, 6122, 6123, and 6124, which can all be OLED light emitting panels and can be driven independently, with the light emitting direction out of the plane of the paper. The four regions may be a single OLED light-emitting panel (especially when the OLED light-emitting panel is a flexible panel) or may be formed by splicing a plurality of OLED light-emitting panels. In some embodiments, a partial region, e.g., 6121 and 6122, is an OLED light emitting panel, while another partial region, e.g., 6123 and 6124, is a mirror. Preferably, all four regions are OLED light-emitting panels. In some embodiments, the area 6121-6124 includes at least two independent OLED light emitting panels, such that multiple panels can be connected by mechanical means and can form different angles with each other after being unfolded, as shown in FIG. 9c, when at least two OLED light emitting panels form a non-planar included angle or arc between them. The design has the advantages that the user can adjust the angle of the light source to achieve the optimal lighting effect and prevent the light source from directly irradiating two eyes to cause visual disturbance. The tube cover housing portion 611 of fig. 9c may also contain an electric drive 630 and is electrically connected to the OLED light emitting panel, which may be hidden in the housing portion 612 and not shown. The electric drive may also be integrated into the cap housing portion 612, and in other embodiments, a portion of the wireless charging device may be integrated into the stem 620, and corresponding electronic components may be integrated into the cap housing 610 to enable wireless charging or control. Electric drive 630 may selectively drive different areas of the OLED light-emitting panel and/or adjust the operating point of the light-emitting panel to achieve dimming. In the embodiment of fig. 9b and 9c, the OLED light emitting panel is integrated inside the cap housing 610, so that the cap housing portion 612 is folded inwards to close the cap shown in fig. 9a when not in use, and encloses the stem 622 and the lipstick body 621 therein, and the area 6121 and 6124 are closed in the cap; when the tube cover is needed to be used, the tube cover shell part 612 is unfolded to expose the areas 6121 and 6124, and all or part of the areas are lightened as required. In another embodiment, a mirror and/or an OLED light source can also be integrated on the outside of the tube cover 610, as shown in FIG. 9d, where the tube cover outside 6125 can be a mirror surface only, or can be an OLED light source. When not in use, the cap housing 612 is folded closed and encloses the tube seat 620 and the lipstick body 621 therein, unlike in FIG. 9b, where the outer side 6125 of the cap is still exposed, so that the whole lipstick has mirror effect when not in use.
FIG. 10a shows a schematic view of another lipstick 700 with an OLED light source, which similarly comprises a cap 710 and a stem 720, the stem 720 further comprising a lipstick body 721 and a stem housing 722. Also, the tube cap 710 and the tube holder housing 722 are both housings for the lipstick 700. The tube cover 710 further includes tube cover housing portions 711 and 712, and an electric drive. The tube cover housing 712 can integrate a flexible OLED light emitting panel, which can be a separate panel or can be formed by splicing multiple panels as shown in fig. 10b, forming regions 7121, 7122 and 7123, where the flexible OLED light emitting panel can be driven independently. In other embodiments, a separate flexible OLED light emitting panel is integrated into the tube cover housing 712, and preferably, the separate flexible OLED light emitting panel is further divided into multiple regions and driven independently, as described above. The flexible OLED light-emitting panel may have a radius of curvature of less than 5cm, preferably less than 3cm, more preferably less than 2 cm. In one embodiment of fig. 10b, the flexible OLED light emitting panel is integrated on either side of the tube cover housing 712, so that when not in use, the flexible OLED light emitting panel can be stored in the tube cover housing 711 like a roll of film, with the area 7121 and 7123 being closed in the tube cover; when it is needed, the flexible OLED lighting panel is unfolded from one end to expose the area 7121 and 7123, and all or part of the area is lighted up as required.
The housing design with OLED light source disclosed in the present invention can be used in many cosmetics, including but not limited to lipstick, lip glaze, mascara, eyebrow pencil, foundation, pressed powder, eye shadow, blush, face powder, highlight powder, hairline pencil, etc., preferably tubular or column type cosmetics.
