Description

Wearable OLED equipment

Technical Field

The present invention relates to an OLED (Organic Light-Emitting Device) Device. And more particularly to a wearable OLED device.

Background

Recent studies have shown that certain wavelengths of light have an impact on health. For example, red light is believed to stimulate collagen growth to eliminate fine lines to tighten pores; yellow light can improve intracellular oxygen exchange, and cause skin cell regeneration; blue light with higher energy can kill the porphyrin-like compounds that cause acne (Kawada, Journal of Dermatologicals science 30(2002) 129-135). This concept has been applied in beauty salons, and some facial treatments use LED light sources to light the patient for medical treatment (https:// www.alibaba.com/product-detail/PDT-7-color-lights-LED-photon _60738799145. html. LED light sources in the form of masks are available for home cosmetic procedures and are already commercially available (https:// detail.1688.com/offer/537712859216. html. In the medical community, deep red or near infrared light sources have been shown to kill bad cells such as cancer cells while growing good cells, such as wound healing and hair growth efficacy (Dong, Photomedicine, OLED summit; Guo, Photodiagnosis and Photodynamics Therapy 2015). Recent news reports have also shown that red LEDs can be used to help lose weight because red light irradiation has been found to shrink adipocytes (https:// www.ledinside.com/news/2015/9/us _ sector _ using _ red _ led _ technology _ to _ aid _ weight _ lo ss). In addition, it has been found that light influences mood. In US 4,777,937 a wearable helmet is described that emits monochromatic light. The flashing helmet, in combination with a pink noise stimulus, can produce a hypersensitive perception effect to aid decompression. In particular, green and blue light is believed to help bring a sense of relaxation. Fraunhofer FEP shows an OLED bracelet that can emit specific wavelengths to aid in wound healing or for the treatment of depression (http:// www.osadirect.com/news/article/2152/frounhofer-fe-hoslt-center-and-vtt-devilop-flex-organic-electronics-for-welable-applications /). In addition, researchers have found that increasing or decreasing insolation can help with the moveout. For example, while flying east, it is generally believed that daylight may help to adjust the traveler's biological clock in the morning, while flying west, it is daylight-intensive in the evening (http:// www.bbc.com/future/store/20140523-the-science-of-jet-lag). However, in a general civil aviation journey, the light of the cabin is dimmed and the shading plate is pulled down, so that extra sunshine cannot be achieved.

Some weight reduction devices including light emitting devices have been commercialized. Near Laser Assisted Lipolysis (NLAL) assembles red LEDs into a soft pad that the customer wears during 20 minutes of exercise. LEDs are high intensity point light sources that typically generate a large amount of heat. Thus, LEDs are typically packaged with a heat sink to dissipate thermal energy, and when used in an array are spaced apart from each other for better heat dissipation. This results in at least three disadvantages. First, the cushion is thick and bulky for safety, in order to incorporate a heat sink and keep heat away from the body. In some cases, this may reduce the efficiency of the physical exercise. Second, such arrays, in which the LEDs are positioned with a spacing arrangement therebetween, do not provide uniform light output. Finally, a plurality of LEDs, 30 diodes, are gathered in the NLAL pad. This makes boxing, assembly and maintenance more difficult.

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 for wearable applications. Nevertheless, the preparation of OLED medical devices and the overall system is very different from LED devices because of the different contrasting form factors of the two light sources. On the other hand, although flexible OLED lighting of various shapes and applications (US 8,773,013, US 8,907,560) has been shown, there are few related to medical functions. When used in medical devices, the design needs to be reconsidered, and there are certain requirements for OLED light sources. Also, depending on the therapeutic purpose, light sources of certain wavelengths may be favored, including in the near infrared spectrum. This requires the development of deep red or near infrared OLEDs. Even with the OLED bracelet demonstrated by the Fraunhofer FEP mentioned above, it is worn as a decoration, which means that light is emitted away from human skin. In our invention, OLED medical devices are worn on or near the human body and emit light towards the human skin.

Flexible OLEDs are key to wearable medical devices. Flexible OLEDs can be fabricated on a variety of flexible substrates including, but not limited to, Polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), metal foil, fabric, leather, paper, and the like. For applications such as facial or eye masks, the device is intended to be conformable, so the substrate may be PI, PET, PEN and not more than 0.3mm thick. When used in a slimming strip, the substrate may be PI, PET, PEN, leather or fabric, and has a thickness of not more than 1 mm. The flat layer can be applied to the prepared side of the substrate, i.e. the side to be coated with the OLED. The substrate may be coated with a thin film encapsulation layer on the prepared side or on both sides. A layer of anode is deposited on the substrate and patterned by a reticle or a reticle. Multiple organic layers are applied to a substrate on which an anode is already disposed, followed by a metal deposition as a cathode. Alternatively, one or more functional layers may be printed on the flexible substrate. The anode, organic layer and cathode constitute a basic OLED device. Materials and methods for preparing anodes, organic layers, and cathodes are well known to those skilled in the art. A thin film encapsulation layer may be added over the cathode. The thin film encapsulation layer may be an inorganic layer or, more preferably, an alternating combination of organic and inorganic layers. At least one pair of contact electrodes, including at least one cathode and one anode, extends outside the package area for external electrical driving. A flexible printed circuit board (FPC) may be printed in advance with a circuit for connecting the flexible OLED to an external driver or internally connecting a plurality of OLEDs. The FPC board may be electrically bonded to the OLED contact electrodes with a conductive paste. The assembly of flexible OLEDs onto FPCs is described in application CN201810572632.3, incorporated by reference in its entirety. In some embodiments, external actuation may be achieved by soldering wires on the electrical contacts. A light diffusing film may be added to the light emitting face of the flexible OLED. A support film may be added to the non-light emitting face of the flexible OLED. A basic OLED device, an encapsulation layer and an external driving scheme are combined with an optional light diffusion film, an FPC board and a supporting film to form an OLED light-emitting panel. The fabrication of flexible OLEDs is well known to those skilled in the art and is not limited to the above description.

A schematic cross-sectional view of a basic flexible OLED light-emitting panel is shown in fig. 1 a. The flexible 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 encapsulation layer 302 exposing the contact electrodes 303, and a bonding structure 304 connecting the pair of contact electrodes 303 to an external driving circuit. OLED device 310 can be a bottom emitting device, or a top emitting device. The encapsulation layer 302 is preferably a thin film encapsulation layer, such as a thin glass, a monolayer of inorganic layers, or alternating layers of organic and inorganic layers. The pair of contact electrodes may include at least one anode contact and one cathode contact. A front cover film 305 may be added to the basic flexible OLED light emitting panel as shown in fig. 1 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. The front cover film 305 may also include a light extraction layer. When OLED device 310 is top-emitting, front cover film 305 may be 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. 1 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. 1d, the back cover film 307 is covered to the substrate 301. The back cover film 307 may be used for mechanical support. When the flexible OLED is a bottom-emitting device, the back cover film 307 may be a light extraction layer. The back cover film 307 may be a combination of the above. Such a flexible OLED light emitting panel will be the basis for the following medical light emitting device.

The first embodiment:

here we disclose OLED medical devices worn around the body with a medical effect to aid in weight loss and/or wound healing. A plan view of an OLED medical device is shown in fig. 2. The OLED medical device 400 includes a housing fixture 401, a flexible OLED lighting panel 402 and a connecting structure 406. The device also comprises a light emitting side 404 and a non-light emitting side 405. In this figure, the light emitting side 404 is out of the viewing plane and the non-light emitting side 405 is into the viewing plane. The housing fixture 401 may be a front cover film (e.g., layer 305 in fig. 1 b), or a back cover film (e.g., layer 307 in fig. 1 d), or a combination of both. In another approach, the flexible OLED lighting panel 402 itself may contain a front cover film 305, or a back cover film 307, or a combination of both, and the housing fixture 401 may be an additional single or double sided film to surround the panel. The material of the housing fixture 401 may be, but is not limited to, plastic, fabric, leather, synthetic material, artificial skin, and the like. The housing fixture 401 may be overmolded onto the flexible OLED lighting panel 402 or may be bonded by heat, pressure or laser melting. The material of the housing fixture 401 is preferably safe for contact with human skin. The attachment structure 406 may be a pair of elastic bands that help wrap the device around the person's body, such as the waist, arms and thigh areas. Other connection structures, such as the structure depicted in fig. 3, may be used. The OLED medical device 500 may comprise a substrate 501, a flexible OLED light emitting panel 502, a light emitting side 504 (out of the viewing plane) and a non-light emitting side 505 (into the viewing plane). On the light emitting side 504 of the device 500, there is a connection structure 503, while on the non-light emitting side 505, there is a corresponding connection structure 506 cooperating with the connection structure 503, so that the apparatus may form a closed loop. Note that the illustration of the elastic band 406 in fig. 2 and the pair of

attachment structures

503 and 506 in fig. 3 is for illustrative purposes only, and any type of attachment technique may be applied here. The flexible OLED light emitting panel 402 may be driven by a wire or an FPC board embedded in the housing fixture 401. In addition, the elastic band 406 may include wires, wireless communication devices, sensors, controllers and/or batteries for driving the OLED device. In another arrangement, the electronic component may be integrated into the substrate, as long as it does not interfere with the light emission.

In some embodiments, as shown in fig. 4, the OLED medical device 600 may contain a plurality of flexible OLED light emitting panels 602 and a housing fixture 601 (the connecting structure is similar to those described above and therefore not shown in the figures). Here, the light emitting side 605 emerges from the viewing surface, while the non-light emitting side 604 enters the viewing surface. These flexible OLED light emitting panels 602 may be driven independently or in groups depending on the color of the emitted light. This configuration produces devices with a small active area for high yield, and the advantage of flexible binning and sorting of high performance OLED panels. Additionally, if the device is curved in the x-direction, at least two light emitting areas may have a gap in the x-direction to facilitate a small radius of curvature. In another approach, the flexible OLED lighting panel 602 may comprise a plurality of pixels that are also driven independently or in groups of light emission colors. Another advantage of such a pixelated light emitting device is local treatment. For example, when used in a weight loss belt, one may only want to treat the lateral abdominal muscles, in which case the entire device may be worn around his waist, but only the light emitting pixels that are in contact with the sides of the waist are turned on. This saves energy and extends the life of the device. In another case, the device may be wrapped around a wound and only pixels covering the wound area may be illuminated. Moreover, such a pixelated device may enable multifunctional therapy. For example, the pixels 602 may further include at least one pixel emitting blue light with a peak wavelength between 400-500nm, at least one pixel emitting green/yellow light with a peak wavelength between 500-580nm, and at least one pixel emitting red light with a peak wavelength between 580-800 nm. When wearing an OLED medical device, the green/yellow pixels may be turned on for wound healing and the red pixels turned on to reduce weight. In some other embodiments, the pixel 602 may further include at least one pixel emitting light with a peak wavelength between 580 and 700nm, and at least one pixel emitting light with a peak wavelength between 630 and 800 nm. The use of two red pixels helps to achieve deep red or near infrared emission while maintaining good device lifetime.

In use, the OLED medical device may be worn on the abdomen, waist, thigh, arm or any other desired treatment area of a user with the light emitting side in close contact with the skin of the human body. This is fundamentally different from the Fraunhofer bracelet used as fashion jewelry or wearable displays for the wearer to view (Pang, Proceedings of SPIE (2011) attached paper, 7956,79560J-1.). Biosensors may be assembled in the apparatus, preferably in the housing fixture, to monitor the physical capabilities of the user, such as lean lipid mass ratio, weight changes, glucose levels, etc. Furthermore, a wireless communication device may be integrated such that the lighting may be controlled and connected to other electronic devices, such as a user's phone, a smart watch, a computer, etc. The information collected by the biosensor can be displayed on other devices and dynamically controlled for the power or intensity of the OLED medical device.

Second embodiment

In this embodiment, we disclose an OLED mask with medical treatment. As shown in fig. 5, the OLED face film 700 has a housing fixture 701 and a flexible OLED light emitting panel 702. Similar to those in the first embodiment, the housing fixture 701 may be a front cover film, a back cover film, or a combination of both. In another approach, the flexible OLED panel 702 may already include one or both of the front and back cover films, and the housing fixture 701 may be an additional support film. Also, although drawn here as one component, the OLED panel 702 may be pixelated. The apertures 703 may include, but are not limited to, an eye region, a nose region, and a mouth region. When converting from a 2D sheet to a 3D conformal mask, there may be additional cuts 704, for example, to aid in the expansion of the mask. Note that the holes 703 and cutouts 704 are merely illustrated here, and the design of such structures is well known to those skilled in the art. These cuts may be made by laser cutting. The attachment structure is represented by ear hook 705 in fig. 5. Alternatively, a headband may be used as described previously, but is not shown here. Here, the light emitting side is 706, which comes out of the viewing plane, and the non-light emitting side 707, which enters the viewing plane. In use, the user wears the OLED mask with the light emitting side 706 facing the face. In other embodiments, two halves of the mirrored OLED facing film can be bonded together to form a unitary body. The drive scheme may be integrated in the connection structure or housing fixture as described above.

The OLED mask may provide the following possible therapeutic effects, but is not limited to:

The OLED eye cup also includes a light emitting side 804 (out of plane) and a non-light emitting side 805 (into plane). The eye patch 800 may include a sheet of flexible OLED panel 802, or the two light emitting areas 802 may be from two separate flexible OLED panels and joined together in the middle. The two light emitting regions 802 may be electrically driven in parallel. Likewise, the elastic band 803 may include wires or cables for an external drive and battery. The controller and wireless communication device may further be incorporated into the eye shield to provide remote control. Similarly, the flexible OLED panel 802 may also include RGB OLED pixels.

The OLED eyewear may provide possible medical effects, but is not limited to:

1. when the white light is emitted, the time difference reaction is slowed down by imitating sunlight;

2. promoting sleep environment when the light emitting wavelength is greater than 580 nm;

Also, it has one light emitting side and one non-light emitting side. The piece of OLED device is worn on the head of a user like a hat and has the light emitting side directed toward the head, emitting red or deep red light which is considered to stimulate hair growth. The housing fixture may be shaped like a hat. In another approach, the adhesive may be provided on the non-light emitting side of the OLED light emitting panel so that it may be previously pasted on the inside of a general hat. A user can wear the cap with the integrated OLED while performing the hair growth treatment without being aware of the hair growth treatment.
