Description

Portable phototherapy glasses

Technical Field

The invention relates to portable phototherapy glasses. And more particularly, to portable phototherapy eyeglasses using OLED light-emitting panels as light sources.

Background

Technologies such as Low Light Laser Treatment (Low Light Laser Treatment) and Photo Biological Modulation (PBM) appear in the middle and later stages of the 20 th century, and both technologies are applied to the medical field by taking illumination as a means for treating diseases (Michael r. Several studies have shown that red to near infrared illumination is found to help promote the regeneration of tissues such as collagen and skin cells, and can be applied in the fields of anti-wrinkle cosmetology, wound healing promotion, spot removal, etc. (Chan Hee Nam et al, dermotologic Surgery,2017, 371-380, daniel barolet, semin Cutan Med surg,27, 227-238,2008, 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-), are already in use.

Nowadays, people pay more and more attention to the problems of facial skin, especially eyes. A variety of phototherapy devices for anti-aging and tightening the skin of the eyes have been used in beauty salons, for example, LED eye masks have been commercialized in the market. These products have LED chips arrayed on the back of a plastic eyecup. 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 eyecup. First, the eye mask is thick and heavy because it must incorporate a heat sink for heat dissipation and must be spaced from the face for safety. This results in discomfort and inconvenience in wearing the eye. Second, in the array arrangement, the LEDs are all independent at a certain position, and there is a space between them, which results in non-uniform light emission. In cosmetic treatments, such uneven lighting may introduce uneven skin tone or require multiple treatments in different areas. Finally, such eye shields are opaque and do not allow the wearer to view the outside world during use.

In contrast, OLED is a surface light source, a cold light source, is not glaring, and has a light and thin property, making it very easy to integrate into a flexible substrate. This makes OLEDs ideal light source options for wearable applications, and the related patent applications also cover various fields in recent years. For example, CN205108772U, CN204951964U and CN102481456A all disclose the use of OLED light sources as wearing products for medical treatment. CN203694423U and CN109173071A disclose the preparation of phototherapy masks using OLEDs, but all are substantially full-face covering; even though treatment for eyes is mentioned, the eyes are shielded, and a wearer cannot observe the outside during use. Phototherapy glasses using OLEDs as light sources are also described in patents CN209734312U, CN205108772U, CN109173071A and CN108783778A, but these phototherapy glasses are also opaque when used, so that the wearer can only close the eyes to receive treatment and cannot perform normal work and life. The inventor's prior application CN111538171A discloses a pair of phototherapy glasses, which integrates OLED light sources on a transparent lens and arranges the transparent lens in an array form with a filling factor less than 80%, so that the whole lens still has high transparency, and normal eye use can be not hindered while phototherapy is performed on eye skin. However, the distance between each OLED light source array is not uniform, and thus, the whole position around the eyes cannot be well taken care of. Furthermore, the plurality of OLED light emitting units in this application must be supported by the lens and cannot exist independently. CN209933849U discloses a pair of glasses suitable for eye care, in which it is described that an OLED patch can be attached to a lens in a ring-shaped form, and light therapy can be performed on the eyes while leaving a part of the area for observing the outside. Likewise, the OLED patch in this application must also be lens-dependent and cannot stand alone; and the application neither describes how such an OLED patch is powered, nor does it describe the size or design of the patch that can be unobstructed for viewing. Finally, all of the above inventions do not mention how to store the eyeglasses.

Due to the rapid pace of modern life, people have more demands on beauty products, and people hope to provide phototherapy beauty without influencing the normal affair to maximize the utilization time. In addition, people prefer portable products so as to be used anytime and anywhere. Based on the practical problems, the invention provides portable phototherapy glasses using an OLED light-emitting panel as a phototherapy light source.

A typical single layer OLED device 100 is shown in figure 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 has a transparency of generally more than 50%, preferably more than 70%; the cathode layer 109 is a material having a high reflectivity, including but not limited to Al, ag, etc., greater than 70%, preferably 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, greater than 80%; more preferably, greater than 90%. And the cathode layer 109 should be a semi-transparent or transparent conductive material including, but not limited to, mgAg alloy, moOx, yb, ca, ITO, IZO or combinations thereof, which typically have a transparency greater than 30%; preferably, greater than 50%. In a double-sided light emitting device, the anode layer 101 and the cathode layer 109 are both transparent or translucent materials, so that the device can emit light from both sides of the anode and the cathode, respectively. In this case, the transparency of the two electrode layers can be adjusted to control a side to emit more or less light, for example, if the anode layer has a higher transmittance than the cathode layer, the anode layer emits more light than the cathode layer, and vice versa. The electron transport layer 107 may be a single layer of Yb, liQ, or LiF. The light-emitting layer 105 typically also contains at least one host material and at least one light-emitting material, while the electron blocking layer 104 and the hole blocking layer 106 are optional layers, and the capping layer 110 is not required in bottom-emitting devices. 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 material in a proportion, typically not higher than 5%, usually between 1% and 3%. Fig. 1b shows a structure of a multicolor OLED device 130, where the light-emitting layers may include a red light-emitting layer 1051 (with an emission wavelength between 600-750 nm) and a near-infrared light-emitting layer 1052 (with an emission wavelength between 750-1400 nm) without changing other layers, and it is noted that the order of the two light-emitting layers may also be reversed, that is, the light-emitting layer 1051 is a near-infrared light-emitting layer and the light-emitting layer 1052 is a red light-emitting layer. The OLED device with the structure can emit red light and near infrared light simultaneously. FIG. 1c shows the structure of a variable color OLED device 120 with a red light emitting layer 1053, a near infrared light emitting layer 1055 and an adjustment layer 1054. The adjusting layer 1054 can adjust and control the movement of electron holes under different current densities, thereby realizing the adjustment and control of colors. For example, at low current densities, the exciton recombination zone is primarily near the cathode side, i.e., in the red light emitting layer 1053, the OLED device 120 can emit red light; when the injection is gradually increased and the voltage and current density are increased, the exciton recombination region moves toward the anode side and finally enters the near-infrared light emitting layer 1055, and the oled device 120 emits near-infrared light. Of course, the light-emitting layer 1053 may emit near-infrared light and the light-emitting layer 1055 may emit red light, and 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 shown in fig. 2, and includes an anode layer 201, a first light emitting unit 202, a 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 102 to 108 in the single-layer light-emitting device 100, and the light-emitting layers of the first light-emitting unit and the second light-emitting unit may be the same or different. The first and second light emitting units may emit light of the same color, such as red light having a wavelength of 600-750 nm; the first and second light emitting units 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 wavelength between 750-1400nm, in which case the device 200 may emit both red and near infrared light. The charge generation layer 203 is generally made of an n-type material and a p-type material, and may also be supplemented by buffer layers, 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 not described in detail herein.

One light source used in portable 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, preferably flexible, including but not limited to ultra-thin flexible glass, PET, PEN, PI, etc. In particular, the substrate 301 may be a material (e.g., polyimide material) that is coated on the support base plate in a solution form 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 may be a bottom emitting device or a top emitting device, preferably a top emitting device 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 it has a longer lifetime at the same luminance and because a thicker film layer is beneficial for improved 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 encapsulation layer 302 may be glass adhered to the device by UV curable adhesive, preferably a thin film encapsulation layer, generally having a thickness of 10 μm or more, such as a single inorganic layer, or a thin film organic-inorganic alternating multilayer structure, and formed by PECVD, 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 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 an FPC board to drive an OLED light-emitting panel can be found in patent application US20190376650A1, which is incorporated by reference in its entirety, which is not the subject of the present study and is not described in any further detail. 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. 3 c. The front cover film may also be coated with an additional thin film encapsulation layer 306, but this is not shown in the figures. 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 emission 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 an OLED light source when electrically driven to form an electrical connection with an external device (regardless of whether it is in an on or off state), and is one of the essential components of the present invention.

The OLED light source used in the phototherapy glasses may emit light comprising a peak wavelength in the range of 400-2000nm, preferably in the range of 500-1400nm, more preferably in the range of 600-1000nm, still more preferably in the range of 630-970 nm. For the eye region, the most common medical purposes are wrinkle resistance, skin regeneration, macula removal, even inflammation (e.g. the appearance of hordeolum), wound healing, scar reduction, etc. According to studies it has been shown (Daniel Barolet, semin Cutan Med Surg,27, 227-238, 2008) that light with a wavelength between 630 and 970nm has an effect on both of the above mentioned medical effects. In one embodiment, a pair of phototherapy glasses can integrate OLED light-emitting panels emitting different wave bands in one area, for example, red light with the peak wavelength of 630nm is used for treating wrinkle resistance and freckle removal in the periphery of eyes, and near infrared light with the peak wavelength of 750nm or more can be emitted completely at some time.

There are several ways to achieve light with a variety of different wavelength bands in phototherapy glasses: the first is to design a pixelized layout on the same OLED light-emitting panel and then independently drive each pixel, or to group pixels and then independently drive different groups. 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 millimetres, i.e. a minimum dimension greater than 1mm ² Preferably greater than 5mm ² . For example, a flexible OLED light emitting panel 500 shown in fig. 5a may include a flexible OLED substrate 501 on which a series of OLED devices 502 are patterned, and these devices share the 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 is a flexible OLED light emitting panel 510 as shown in fig. 5b comprising a flexible OLED substrate 501, a series of OLED devices 502, but each device enjoys a separate encapsulating layer 513, and preferably a thin film encapsulating layer. At this time, the different OLED devices 502 can be connected through not only metal wiring but also an FPC board, which greatly improves the possibility of conductivity and circuit complexity. 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, individual OLED light emitting panels may be arranged in an array, as shown in fig. 5c, where each light emitting panel comprises an individual substrate 521, an OLED device 502 and an individual encapsulating layer 513. The advantage of this arrangement is that the non-flexible OLED light-emitting panel and/or the non-flexible encapsulation layer can be selected, and the light source formed into the array still has certain flexibility as long as the area is small enough. 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 may be arranged and combined through an FPC or front and rear cover films, etc. as required, to form a dot matrix physically connected to each other, which may specifically refer to the method disclosed in CN208750423U, which is not the content of the research in this application and is not described again. Also, the panels may be independently controlled to apply different operating currents. The array arrangement can realize multicolor luminescence and zone control, such as using different wavelengths of light to the periocular and temple regions to achieve different therapeutic effectsOr the illumination intensity or illumination duration of different areas is different, the local illumination can further reduce the power consumption and save the energy.

Fig. 4a shows a schematic diagram of a portable phototherapy glasses 400, wherein OLED light emitting panel area 4011, OLED light emitting panel area 4012 and OLED light emitting panel area 4041 cover the periocular and caudal-to-sideburns respectively, which may emit light comprising a peak wavelength in the range of 400-2000nm, preferably 600-1000 nm. The OLED light-emitting

panel regions

4011 and 4012 may be composed of two OLED light-emitting panels or four or more light-emitting panels, and preferably, the light-emitting panels are flexible light-emitting panels. The OLED light-emitting panel region 4041 may also be formed by two OLED light-emitting panels, preferably flexible light-emitting panels. The OLED light emitting panel may be integrated on the housing 406, and the housing 406 may be made of a flexible material, including but not limited to, textiles, plastic films, etc.; the housing 406 may also be rigid, such as plexiglass, or the like. Note that the housing supports and holds the OLED panel, which may be discontinuous, or in the form of a frame. The OLED light panel may not need to be integrated into the housing 406, especially when a rigid light panel is used, which may itself be worn as eyeglasses, but may be formed by splicing together by means of attachment means. The eye region 402 of the phototherapy glasses 400 is a hollow design, and the wearer can directly observe the outside. The first connecting means 403 is not integrated with the OLED light emitting panel and is made of a flexible material or a foldable structure, and the first connecting means 403 mainly covers the bridge of the nose and connects the OLED light emitting panel region 4011 and the OLED light emitting panel region 4012. The second connecting means 405 may also be made of a flexible material or a foldable structure, which connects the OLED light emitting panel area 4011, the OLED light emitting panel area 4012 with the fixing means 404. The first connecting means 403 and the second connecting means 405 may be flexible, i.e. they may be bent directly, or if they are rigid, they may be hinges, or the like. The first 403 and second 405 connection means may be in direct contact with the respective OLED light emitting panel, may be connected to the housing 406, or may be part of the housing 406. The fixing means 404 comprises an OLED light emitting panel area 4041 and an area 4042 without integrated OLED light emitting panel, between which further third connecting means (not shown here) may be comprised. The 4042 region of the securing device may be an elastic band, a strap, a temple, an ear hook, or the like. Such portable phototherapy glasses 400 also comprise driving means, which may be integrated in the fixation means 404, in particular in the region 4042. The driving device includes, but is not limited to, a battery, a control chip, a lead, a circuit board, a bluetooth communication system, a wireless charging system, and the like. The driving device may further include an external electrode 4043 for external charging, and the external electrode may be in various forms including, but not limited to, an electrode tab, a metal contact, a USB interface, and the like. The drive means are not shown here as being integrated inside the fixing means. The driving device can also realize wireless Bluetooth connection with external electronic equipment and be controlled by the external electronic equipment, such as a switch, dimming control, partition control and the like. The external electronic device can be a smart phone, a smart watch, a tablet computer, a notebook computer, a computer and the like. Furthermore, the control can be combined with an application program (APP).

One way to fold the phototherapy glasses is also shown in fig. 4 a. Firstly, folding the phototherapy glasses along the directions A1 and A2 (dotted arrows) along a folding line AA' to enable the light emitting panel area 4011 and the light emitting panel area 4012 to be overlapped, and folding the light emitting panel area 4041 of the fixing device to be reduced to a half; next, the second connecting means 405 is folded in the directions C0 and D0 along fold lines CC 'and DD' so that the light-emitting panel region 4041 of the fixing means 404 partially overlaps the light-emitting

panel regions

4011 and 4012; finally, the first connecting device 403 is folded along the folding line BB' along the direction B0. Note that the above folding sequence is only an example, and may be re-ordered according to design, such as folding along BB ' first, then folding along CC ' and DD '; or a portion may be omitted, for example the fold along fold line AA' may be omitted. One type of eyeglass assembly 410 for portable phototherapy eyeglasses is shown in fig. 4b, which shows portable phototherapy eyeglasses 400 folded into housing 412 with light panel area 4011 coinciding with light panel area 4012 and with light panel area 4041 of fixture 404, noting that portion 4042 of the fixture is shown here for illustrative purposes only. The maximum size of the folded phototherapy spectacles does not exceed 10cm and can be accommodated in the housing 412. The housing 412 in fig. 4b has a cuboid design with a length L, a width W, and a height H, but it is noted that this is only an illustration and the housing 412 can be of another design as long as it has a minimum volume to accommodate the folded phototherapy spectacles. Preferably, the length L of the housing 412 is no greater than 12cm, preferably, no greater than 10cm; the width W of the housing 412 is no greater than 10cm, preferably no greater than 8cm; the height H of the housing 412 is no greater than 3cm, preferably no greater than 1cm. If the housing 412 is of another design, such as a crescent-shaped box, cylinder, oval cylinder, etc., its maximum dimension is no greater than 12cm, preferably no greater than 10cm, where "maximum dimension" refers to the maximum distance between two points in a continuous plane of the housing. The housing 412 may further include an external charging interface 4121 and an internal charging electrode 4143 corresponding to the external electrode 4043 on the phototherapy glasses 400. When the glasses are placed back in the housing 412, the external electrode 4043 is electrically connected to the internal charging electrode 4143 in the housing, and then the phototherapy glasses 400 can be charged by connecting an external driver through the external charging interface 4121.

Another schematic diagram of a portable phototherapy glasses 420 is shown in fig. 4c, which differs from fig. 4a mainly in that the OLED light emitting

panel area

4211 and 4212 cover the whole eye, at this time the OLED light emitting panel emits light in the near infrared and infrared bands, which contains light with a peak wavelength of 750nm-2000nm, preferably 800-1000 nm. Since the emitted non-visible light is non-visible, although the OLED light-emitting panel covers the whole eye, the wearer can directly observe the outside by preparing the transparent panel as described in the inventor's prior application CN 111538171A. Or the structure of the double-sided light-emitting OLED device can be directly used, namely, the cathode and the anode are made of transparent or semitransparent materials, so that when the device is not lightened, the whole panel has the transmittance of more than 30 percent, and preferably the transmittance of more than 50 percent; when the device is lighted, although near infrared light is emitted toward human eyes and in the opposite direction, the sight line is not disturbed because the device is not visible light. In particular, the intensity of the emergent light at one side can be controlled by selecting the transmittances of the anode layer and the cathode layer, for example, an OLED device can be prepared by using a cathode made of MgAg alloy (Mg: ag ratio is 1. The region 4041 of the fixture 404 also integrates an OLED light-emitting panel, but light in the visible wavelength band with a peak wavelength above 400nm can still be used because it is not directly blocked in front of the human eye. One way of folding the phototherapy spectacles 420 as shown in fig. 4C is to fold the second connection means 405 along the C0 and D0 directions along fold lines CC 'and DD' such that the OLED light panel area 4041 on the fixing means 404 coincides with the OLED light panel area 4211 or the OLED light panel area 4212; the second connecting means 403 is then folded along the fold line BB' in the direction B0. The final folded phototherapy spectacles 420 may be received in the housing 432, a spectacle assembly plan view 430 of the portable phototherapy spectacles being shown in fig. 4d, wherein the

light panel area

4211 and 4212 of the folded phototherapy spectacles coincide, on which the light panel area 4041 of the fixing device is superimposed, and the maximum size thereof does not exceed 10cm. Here the housing 432 is an oval box having a maximum dimension D of no more than 12cm, preferably no more than 10cm; the height H of the housing 432 is likewise not greater than 3cm, preferably not greater than 1cm. Similarly, the housing 432 may further include an external charging interface 4321 and an internal charging electrode 4343, and the internal charging electrode 4343 is coupled to and electrically connected to the external electrode 4043 of the phototherapy glasses 420, so that the phototherapy glasses 420 can be charged through the external charging interface 4321.
