Description

Phototherapy eye-shade

Technical Field

The invention relates to a phototherapy eyeshade. More particularly, the invention relates to a phototherapy eyeshade which can perform phototherapy on skin around eyes to achieve the effect of removing wrinkles and tightening the skin, and meanwhile, the phototherapy eyeshade does not obstruct normal eyes.

Background

Technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and photobiological modulation (PBM) appear in the middle and later stages of the 20 th century, and both of them are applied to the medical field by using illumination as a means for treating diseases (Michael r. There are several research surfaces that red to near infrared illumination helps to promote regeneration of tissues such as collagen and skin cells, and can be applied in the fields of anti-wrinkle cosmetology, promotion of wound healing, depigmentation, stimulation of hair growth, etc. (Chan Hee Nam et al, dermotologic Surgery,2017, daniel barolet, semin Cutan Med surg, 27-227, 2008, yongmin jeon, adv. Meanwhile, blue light irradiation is also the most effective means for treating pediatric jaundice at present, and phototherapy products using semiconductor Light Emitting Diodes (LEDs) as light sources and integrated on flexible substrates are gradually emerging (US 6811563B2, US6596016B1, US6974224B 2), and even commercial phototherapy blankets for treating neonatal jaundice, such as BiliTX products of Philips (https:// www. Philips. Com. Cn/healthcare/product/HC 866437/biltix-).

Various phototherapy devices aimed at anti-aging skin are already applied in beauty salons, for example, commercial LED masks are already available on the market. These products arrange the LED chips in an array on the back of a plastic face mask. LEDs are high intensity point sources of light, often accompanied by heat generation. LED light sources typically incorporate heat sinks to reduce temperature, and the LEDs must be spaced apart for heat dissipation when used in an array format. This results in three disadvantages of the LED mask. First, such masks are thick and heavy because heat dissipation considerations necessitate the addition of a heat sink and must be located some distance from the face of the person for safety. Some of these masks weigh up to 1.6 kilograms and the comfort of wearing on the face is compromised. Second, in the array arrangement, the LEDs are all independent at a certain position and have a distance therebetween, which results in non-uniform light emission. In cosmetic treatments, such uneven lighting may lead to uneven skin tone or require multiple treatments in different areas. Finally, to cover the entire face, a large number of LEDs, sometimes as many as 200 chips, need to be used. This increases the difficulty of LED screening, assembly and maintenance.

In contrast, OLEDs are a surface light source, a cold light source, non-glare, and lightweight features that make them very easy to integrate onto flexible substrates. This also makes OLEDs ideal light source options for wearable applications, and related patent applications have also covered various areas in recent years. Chinese patent CN205108772U, CN204951964U and chinese patent application CN102481456A all disclose that OLED light sources are applied to wearable products for medical treatment. The application of OLEDs to phototherapy masks is disclosed in chinese patent CN203694423U and chinese patent CN210009521U prior to the present inventors. However, these devices cover the entire face, and even though they disclose that treatment can be performed on the eyes, they are designed to block both eyes, and the wearer cannot observe the outside during use. The inventor's prior chinese patent application CN111538171A discloses a phototherapy glasses, in particular, it is required to prepare transparent OLEDs or arrange OLED dot matrix to achieve visual transparency, and such glasses generally use hard luminous panel. Phototherapy eyeshades using OLEDs as light sources are also described in chinese patents CN209734312U, CN205108772U, CN210009521U and chinese patent application CN108783778A, but these phototherapy eyeshades are also opaque when used, and the wearer can only close his eyes to receive treatment, and cannot perform normal working life. Chinese patent CN209933849U discloses an OLED patch screen suitable for eye care, which can be attached to a lens in a ring shape, and can perform phototherapy on eyes while leaving a part of the area for observing the outside. However, this application does not describe how such an OLED patch can be powered, nor how the patch can be sized or arranged so as to provide a non-obstructing view. Also, the application discloses eyewear and designs suitable for use on eyewear, which are substantially different from the flexible eyewear covers of the present invention.

A schematic diagram of a typical single-layer OLED device 100 is shown in fig. 1 a. The OLED device 100 includes 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, a cathode layer 109, and a capping layer (CPL) 110. In a bottom emission device, the anode layer 101 is a transparent or semi-transparent material, including but not limited to ITO, IZO, moOx (molybdenum oxide), etc., which typically has a transparency of greater than 50%; preferably, the transparency is greater than 70%; the cathode layer 109 is a material with high reflectivity, including but not limited to Al, ag, etc., with reflectivity greater than 70%; preferably, the reflectivity is greater than 90%. In a top-emitting device, the anode layer 101 is a material or combination of materials with high reflectivity, including but not limited to Ag, ti, cr, pt, ni, tiN, and combinations of the above with ITO and/or MoOx (molybdenum oxide), typically with a reflectivity of greater than 50%; preferably, the reflectance is greater than 80%; more preferably, the reflectivity is greater than 90%; the cathode layer 109 should be a translucent or transparent conductive material including, but not limited to, mgAg alloy, moOx, yb, ca, ITO, IZO or combinations thereof, typically having a transparency greater than 30%; preferably, the transparency is greater than 50%. The hole injection layer 102 may be a single layer of material, such as the commonly used HATCN; the hole injection layer 102 may also be a hole transport material doped with a p-type conductivity dopant at a doping rate of usually not higher than 5%, usually between 1% and 3%. The light-emitting layer 105 typically also comprises at least one host material and at least one light-emitting material. The electron blocking layer 104 and the hole blocking layer 106 are optional layers and the capping layer 110 is not required in a bottom-emitting device. The electron transport layer 107 may be a single layer of Yb, liQ, or LiF. FIG. 1b shows a schematic diagram of a multicolor OLED device 130, which can comprise a light-emitting layer 1051 and a light-emitting layer 1052, wherein the peak wavelength of the light-emitting layer 1051 can be between 600-750nm (red light emission) and the peak wavelength of the light-emitting layer 1052 can be between 750-1400nm (near infrared light emission), with the remaining layers unchanged. Note that the order of these two light emitting layers may also be reversed, that is, the light emitting layer 1051 emits near infrared light and the light emitting layer 1052 emits red light. The OLED device with this structure can emit red light and near infrared light simultaneously.

Of course, the light-emitting layer 1053 may emit near-infrared light and the light-emitting layer 1055 may emit red light, or vice versa. Reference may be made in particular to the present inventors' previous patent applications CN111081891A and CN111081892A for the structure and use of the adjustment layer of a variable color OLED device.

A typical stacked OLED device 200 is schematically shown in fig. 2, and includes an anode layer 201, a first light emitting unit 202, a first Charge Generation Layer (CGL) 203, a second light emitting unit 204, and a cathode layer 205. The first light-emitting unit 202 and the second light-emitting unit 204 may further include a series of organic layers from the hole injection layer 102 to the electron injection layer 108 in the single-layer light-emitting device 100, and the light-emitting layers of the first light-emitting unit 202 and the second light-emitting unit 204 may be the same or different. The first light emitting unit 202 and the second light emitting unit 204 may emit lights of the same color, such as red lights each having a peak wavelength between 600-750 nm; the first light emitting unit 202 and the second light emitting unit 204 may also emit light of different colors, for example, the first light emitting unit 202 emits red light, and the second light emitting unit 204 emits near infrared light with a peak wavelength between 750nm and 1400nm, in which case the device 200 may emit red light and near infrared light at the same time. The first charge generation layer 203 is generally made of an n-type material and a p-type material, and a buffer layer may also be added, as described in patent application CN 112687811A. If the stacked device is a top-emitting device, a capping layer (not shown) may also be added over the cathode layer 205. Fig. 2 shows a 2-unit stacked device, and a 3-unit stacked device formed by a third light-emitting unit and a second charge generation layer can be added on the basis of the 2-unit stacked device. The fabrication of both single and stacked OLED devices is well known in the art and will not be described in detail herein.

One light source that may be used in phototherapy eyewear is an Organic Light Emitting Device (OLED). A schematic cross-sectional view of an OLED light-emitting panel is shown in fig. 3a-3 d. In fig. 3a, 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, an 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 rigid, such as glass, or may be flexible; preferably, the substrate 301 is flexible, including but not limited to ultra-thin flexible glass, PET (polyethylene terephthalate), PEN (polyethylene naphthalate), PI (polyimide), and the like. In particular, the substrate 301 may be a material (e.g., PI material) that is previously coated on a support substrate in the form of a solution, 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, and preferably, OLED device 310 is a top emitting device because of its higher luminous efficiency. OLED device 310 can be a single layer structure or a stacked layer structure, and preferably OLED device 310 has a stacked layer structure because it has a longer lifetime at the same brightness and because the film layer is thicker, which is beneficial 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 entirely by 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 encapsulation layer 302 may be glass adhered to the device by UV curable adhesive, preferably a thin film encapsulation layer, which is typically more than 10 μm thick, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, and is formed by Plasma Enhanced Chemical Vapor Deposition (PECVD), atomic Layer Deposition (ALD), printing, spin coating, etc. If both the substrate 301 and the encapsulation layer 302 are flexible, the entire OLED light emitting panel is flexible; the contact electrode 303 may comprise at least one anode contact and at least one cathode contact. A front cover film 305 may be added to the OLED light emitting panel described above as shown in fig. 3 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 FPC boards to drive OLED light emitting panels can be found in patent application US20190376650A1, which is incorporated by reference in its entirety and which 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 a top-emitting device, 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. 3 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. 3d, 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. One of the essential elements of the present invention is that such an OLED light-emitting panel is an OLED light source when electrically connected to an external power source (whether in an on or off state).

The OLED light source used in the phototherapy eyeshade may emit light having a peak wavelength between 400-2000nm, preferably between 500-1400nm, more preferably between 600-1000nm, and even more preferably between 630-970 nm. For the eye and forehead area, the most common medical purposes are anti-wrinkle, skin regeneration, spot removal, even anti-inflammation (such as hordeolum and acne), wound healing, scar reduction, etc. According to studies, light with a peak wavelength between 630 and 970nm has been shown to contribute to the above-mentioned medical effects (Daniel Barolet, semin Cutan Med Surg, 27. The light with the peak wavelength of about 630nm also has obvious treatment effect on the actinic keratosis, and the light with the peak wavelength of about 650nm has hair growth effect. In one embodiment, a phototherapy mask may integrate OLED light panels emitting different wavelength bands in one area, such as using near infrared light with peak wavelength above 750nm for wrinkle reduction and macula removal treatment on forehead and eye circumference, and using light with peak wavelength above 650nm for hair growth treatment at hairline.

There are several ways to achieve light with a variety of different wavelength bands in phototherapy eye masks: the first is to design a pixelized layout on the same OLED light-emitting panel and then drive each pixel independently, or group pixels and then drive different groups independently. OLED light emitting panels may be flexible or inflexible; preferably, a flexible OLED light-emitting panel is used, i.e. encapsulated with a flexible substrate and a thin film. The pixels here usually have a light-emitting area in the order of millimeters, i.e. a minimum dimension of more than 1mm ² Preferably greater than 5mm ² . For example, fig. 5a is a schematic structural diagram of a flexible OLED light-emitting panel 500, which may include a flexible OLED substrate 501 on which a series of OLED devices 502 are prepared by patterning, and the devices share a same thin film encapsulation layer 503, in this case, each light-emitting unit is an OLED device, and the whole flexible 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. Different OLED devices are controlled by the circuit control system, so that different devices can emit light with different colors, or the same device works under different currents, and multiple colors are realized. A variation of this scheme is the schematic structure of a flexible OLED lighting panel 510 as shown in fig. 5b, comprising a flexible OLED substrate 501, a series of OLED devices 502, but each device shares a separate encapsulation layer 513, and preferably the encapsulation layer is a thin film encapsulation layer. The different OLED devices 502 can now be connected not only by metal wiring,and the electric connection can be carried out through the FPC circuit board, so that the possibility of conductivity and circuit complexity is greatly improved. Also, a single or multiple OLED devices 502 can be independently driven through these electrical connections. Under the two conditions, if light with different colors is emitted, different device structures can be evaporated on different OLED devices by using a metal mask, and particularly, the material of a light emitting layer is changed; it is also possible to refer to the arrangements of multiple light-emitting layers of the same independent unit, all of the devices using the movement of the recombination zone at different working points, as described in applications CN111081892A and CN111081891A, to achieve a change in colour. Alternatively, the structure of the light-emitting panel 520 is schematically illustrated in fig. 5c, where each OLED light-emitting panel comprises a separate substrate 521, an OLED device 502 and a separate encapsulating layer 513. The advantage of this arrangement is that non-flexible OLED light-emitting panels and/or non-flexible encapsulation layers can be used, as long as the area of each OLED light-emitting panel is small enough, and the light source formed into an array still has certain flexibility. The individual OLED light emitting panels may be cut from the same motherboard, for example, using the same individual unit multi-light emitting layer structure, or may be reassembled by selecting different structures of devices from different motherboards. The scheme has the advantages that the device can be screened, the yield is improved, and the color diversity of products is also improved. The independent light-emitting panel shown in fig. 5c can be arranged and combined through an FPC or front and back cover films and the like according to requirements to form a dot matrix physically connected with each other, and particularly, reference may be made to the method disclosed in CN208750423U, which is not in the scope of the present invention. Also, the panels may be independently controlled to apply different operating currents. The array arrangement can realize not only multicolor light emission, but also zone control, such as different treatment effects can be achieved by using different wavelengths of light on the eye circumference, forehead and hairline regions, or the intensity or the light duration of different regions is different. The local illumination can further reduce the power consumption and save energy.

Fig. 4a shows a schematic view of a phototherapy eyeshade 400, which includes a light-emitting region 401, an eye hollow region 402, a nose region 403, and a fixing device 404. The light emitting area 401 further comprises one or more OLED light emitting panels, the specific implementation being described with reference to the above, preferably using flexible OLED light emitting panels. The light emitting region 401 includes at least one or more OLED light emitting panels that emit light toward the human eye. Eye clear area 402 must be completely exposed to the human eye. The fastening means 404 may be a strap, elastic, loop, ear-hook, etc., noting that multiple straps or a pair of ear-hooks/loops may belong to a single fastening means. The driver of the OLED light emitting panel, which is electrically connected to the OLED panel including, but not limited to, one or more of thin film metal, transparent conductive material, FPC leads, and various leads may be integrated in the region of the fixture 404 or the nose region 403.

Furthermore, the control can be combined with an application program (APP). Fig. 4b shows another phototherapy eye patch 410, which comprises temple regions 405 (extended temple regions) in addition to the regions shown in fig. 4a, and OLED light panels integrated in the temple regions 405, which emit light towards the human face. This will further extend the phototherapy area to the extended area of the eyes and even sideburns, especially for consumers with severe fishtail lines. The nose region 403 portion may or may not be illuminated in fig. 4a and 4 b. Fig. 4c shows another eye mask 420, which includes a light-emitting area 421, an eye opening 422, a nose area 423, and a fixing device 424. The eye mask 420 may be designed to be more complete, such as with only one incision in the nose region 423 and the attachment means 424 may be designed as a loop that can be directly attached to both ears. A variation 430 of this design is shown in fig. 4d, and in addition to fig. 4c, the light emitting region 431 of the eye mask 430 further includes a forehead region 4311 (the region surrounded by the dotted line) which also emits light toward the forehead of the human face, so that the eye mask can perform phototherapy on the periocular region and can perform wrinkle removal treatment on the forehead region.

Fig. 6a shows a schematic view 600 of the front view of a phototherapy eyeshade similar to a Venetian mask (showing the side away from the face of a person). The phototherapy eyeshade includes a shell 601, wherein the eye region 602 is a hollow design. In this case, the driving device and a series of leads, electrical connections, etc. can be hidden in the housing 601, preferably, inside or inside the forehead decoration region 603. Note that the region 603 is merely illustrative, and different decoration regions can be provided or regions for hiding the driving and electrical connections can be found according to different design requirements. The housing 601 may be flexible, such as plastic film, fabric, leather, etc., or rigid, such as metal, rigid plastic, etc.; preferably, the housing 601 is flexible. The eye shield also includes a securing device 604 (illustrated as a strap). Fig. 6b is a schematic diagram of a rear view 610 (showing a face facing a human face) of the phototherapy eyeshade, which includes a peripheral region 6051 and a nose region 6052, wherein the peripheral region 6051 may be integrated with an OLED panel to emit light to the human face and cover the peripheral region, and the nose region 6052 may or may not emit light. Of course the light emitting area in fig. 6b is only an example and other designs are possible.

Fig. 7a shows a schematic view 700 of a front view of another phototherapy eyeshade (shown on the side away from the face of a person), which comprises a housing 701, an eye opening 702, a decorative region 703, a driving device such as a lead wire, etc. that can be integrated and hidden in the region of the decorative region 703, and a fastening device (e.g. a strap) 704. Fig. 7b shows a schematic view 710 (the face facing the face) of the rear view of the eye patch, which in addition to fig. 7a includes a light-emitting region 7051 covering a portion of the forehead and hairline regions, a light-emitting region 7052 covering the lower periocular region, a light-emitting region 7053 covering the upper periocular region and a portion of the forehead region, and a non-light-emitting region 7054 (note that this is merely an example, and in some embodiments, region 7054 may also emit light). One or more OLED light emitting panels may be integrated on light emitting regions 7051, 7052, and 7053 and all emit light toward a human face. The gap between light emitting regions 7053 and 7051 in fig. 7b is merely illustrative of the two region boundaries. It can be seen that such a design allows for both treatment of posterior hairline movement and treatment of the skin around the eye, so called a double-effect. The design of the eye mask of fig. 7 comes from the mask inspiration of cartoon characters, cats and women, and the design based on the specific modeling has high identification degree, is more popular in specific people, and makes a wearer not only feel embarrassment but also have identity recognition when using the eye mask. It should be noted that fig. 6 and 7 are only illustrative of the shape of the shell of the phototherapy eyeshade, and that various other designs may be used and are known to those skilled in the art, such as animals, people, or cartoon characters.

The phototherapy eye patch disclosed by the invention is designed in a hollow manner in the eye area, and meanwhile, the phototherapy eye patch is comfortable to wear due to the fact that the light, thin and flexible OLED light-emitting panel is used as a light source, and a wearer is allowed to perform normal business operation while using the phototherapy eye patch. Meanwhile, some special designs are adopted, so that phototherapy on skin around eyes and treatment on hair line backward movement can be considered, and multiple purposes can be achieved. In addition, the device can be controlled by other common electronic equipment such as a mobile phone and the like through the communication device, and is convenient and flexible to use.
