Description

Wearable OLED Devices

technical field

The invention relates to an OLED (Organic Light-Emitting Device) device. More particularly, it relates to a wearable OLED device.

Background technique

Recent studies have shown that certain wavelengths of light have health effects. For example, red light is thought to stimulate collagen growth, which eliminates fine lines and tightens pores; yellow light improves intracellular oxygen exchange, causing regeneration of skin cells; and blue light, which has higher energy, kills porphyrins that cause acne (Kawada, Journal of Dermatological Science 30(2002) 129-135). This concept has been applied in beauty salons. Some facial treatments use LED light sources to illuminate patients (https://www.alibaba.com/product-detail/PDT-7-color-lights-led-photon_60738799145.html ?spm=a2700.details.maylikehoz.2.11ac5ecdx4Xz3g). The LED light source in the form of a face mask can be used for home beauty treatments and is already available in the market (https://detail.1688.com/offer/537712859216.html?spm=a262fl.8287134.2826706.5.65c932c5Fou tTi). In the medical field, 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 (Dong, Photomedicine, OLED summit; Guo, Photodiagnosis and Photodynamic Therapy 2015). There is a recent news report that using red LEDs can also help with weight loss, as red light exposure was found to shrink fat cells (https://www.ledinside.com/news/2015/9/us_doctor_using_red_led_technology_to_aid_weight_lo ss). Additionally, light has been found to affect mood. A wearable helmet emitting monochromatic light is described in US 4,777,937. Combined with a pink noise boost, the flashing helmet can create an extrasensory perception effect to help with stress. In particular, green and blue light are thought to help bring about a sense of relaxation. Fraunhofer FEP demonstrated an OLED wristband that emits specific wavelengths to help wounds heal or treat depression (see Figure 2, http://www.osadirect.com/news/article/2152/fraunhofer-fep-hoslt- centre-and-vtt-develop-flexible-or ganic-electronics-for-wearable-applications/). Plus, researchers have found that increasing or decreasing sunlight exposure can help combat jet lag. For example, when flying east, it is generally believed that more sunlight in the morning can help adjust the traveler's biological clock, while when flying west, more sunlight in the evening should be used (http://www.bbc.com/future/story/20140523 -the-science-of-jet-lag). However, in general civil aviation journeys, the cabin lights will be dimmed and the shades will be pulled down, so it is impossible to achieve additional sunlight.

Some weight reducing devices incorporating light emitting devices have been commercialized. Near Laser Assisted Lipolysis (NLAL) assembles red LEDs into soft pads that clients wear during their 20-minute workouts (see Figure 1). LEDs are high-intensity point light sources that typically generate a lot of heat. For this reason, LEDs are often packaged with heat sinks to dissipate heat energy, and when used in arrays are spaced apart from each other for better heat dissipation. This leads to at least three disadvantages. First, for safety, the pads are thick and bulky in order to incorporate heat sinks and keep heat away from the body. In some cases, this can make physical activity less effective. Second, such arrays, in which the LEDs are positioned with spacing between them, do not provide uniform light output. Finally, multiple LEDs, 30 diodes, are gathered in the NLAL pad. This makes boxing, assembly and repairs more difficult.

On the contrary, OLED is a surface light source, cold light source, not dazzling, and has the characteristics of thin and light, which makes it very easy to integrate on the flexible substrate. This makes OLEDs ideal for wearable applications. Nonetheless, the fabrication and overall systems of OLED medical devices are quite different from LED devices due to the contrasting form factors of the two light sources. On the other hand, although flexible OLED lighting in various shapes and applications has been demonstrated (US 8,773,013, US 8,907,560), few are 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 purpose of the treatment, light sources of certain wavelengths are favored, including the near-infrared spectrum. This requires the development of deep red or near-infrared OLEDs. Even with the wristband shown in Figure 2, it is worn as a decoration, which means that the light is emitted away from the human skin. In our invention, the OLED medical device is worn on or near the body and emits light towards the human skin.

Flexible OLEDs are key to wearable medical devices. Flexible OLEDs can be fabricated on various flexible substrates, including but not limited to, polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), metal Foil, fabric, leather, paper, etc. For applications such as facial masks or eye masks, the device is expected to be fully bonded, so the substrate can be PI, PET, PEN, and the thickness does not exceed 0.3mm. When used for slimming belts, the substrate can be PI, PET, PEN, leather or fabric, with a thickness not exceeding 1mm. The planarization layer can be coated on the prepared side of the substrate, the side to be coated with the OLED. Substrates can be coated with a thin film encapsulation layer on the preparation side, or on both sides. A layer of anode is deposited on the substrate and patterned through a mask or photoresist. Multiple organic layers are applied to a substrate that has been coated with an anode, followed by metal deposition as a cathode. Alternatively, one or more functional layers can be printed on a flexible substrate. 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 can be added over the cathode. The thin film encapsulation layer can 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, extend outside the encapsulation area for external electrical actuation. A flexible printed circuit board (FPC) can be pre-printed with circuits for connecting a flexible OLED to an external driver or internally connecting multiple OLEDs. The FPC board can be electrically bonded to the OLED contact electrodes with conductive glue. For the assembly of flexible OLEDs on FPC, please refer to the application CN201810572632.3, which is incorporated by reference in its entirety. In some embodiments, external actuation can be achieved by soldering wires to the electrical contacts. Light-diffusing films can be added to the light-emitting side of flexible OLEDs. A support film can be added to the non-emitting side of the flexible OLED. A basic OLED device plus encapsulation layer and external driving scheme, together with optional light diffusion film, FPC board and support film, constitutes 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. 3a. 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 an adhesive structure 304 connecting the pair of contact electrodes 303 to the OLED device 310. External drive circuit connection. OLED device 310 may be a bottom emitting device, or a top emitting device. The encapsulation layer 302 is preferably a thin film encapsulation layer, such as thin glass, a single layer of inorganic layers, or alternating layers of organic and inorganic layers. A pair of contact electrodes may include at least one anode contact and one cathode contact. A front cover film 305 can be added to the basic flexible OLED light-emitting panel, as shown in Figure 3b. 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 solution, the adhesive structure 304 can be an FPC frame, and the front cover film 305 can be a piece of plastic film to provide mechanical support. The front cover film 305 may also include a light extraction layer. When the OLED device 310 is top emitting, the front cover film 305 may be transparent in the light emitting area. The front cover film 305 may be a combination of the above. An additional thin film encapsulation layer 306 may be coated on one or both sides of the substrate 301, as shown in FIG. 3c. The front cover film can also be coated with an additional thin film encapsulation layer 306, but this is not shown in the figure. In FIG. 3d , the back cover film 307 is covered to the substrate 301 . Back cover film 307 may be used for mechanical support. When the flexible OLED is a bottom emission device, the back cover film 307 may be a light extraction layer. The back cover film 307 may be a combination of the above. This flexible OLED light-emitting panel will be the basis of the following medical light-emitting devices.

First example:

Here we disclose OLED medical devices worn around the body with the medical effect of assisting weight loss and/or wound healing. A plan view of an OLED medical device is shown in FIG. 4 . The OLED medical device 400 includes a housing fixing device 401 , a flexible OLED light-emitting 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 entering the viewing plane. Housing fixture 401 may be a front cover film (eg, layer 305 in Figure 3b), or a back cover film (eg, layer 307 in Figure 3d), or a combination of both. In another solution, the flexible OLED light-emitting panel 402 itself may contain the front cover film 305, or the rear cover film 307, or a combination of the two, and the housing fixture 401 may be an additional single-sided 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 fixing device 401 can be plastic-sealed onto the flexible OLED light-emitting panel 402, or bonded by heating, pressing or laser melting. The material of the housing fixing device 401 is preferably safe to contact with human skin. Attachment structure 406 may be a pair of elastic straps that help wrap the device around the body, such as the waist, arms, and thigh areas. Other connection structures, such as the one drawn in Figure 5, can be used. OLED medical device 500 may comprise substrate 501, flexible OLED light emitting panel 502, light emitting side 504 (out of viewing plane) and non-emitting side 505 (into 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 which cooperates with the connection structure 503 so that the device can form a closed loop. Note that the illustration of the elastic band 406 in FIG. 4 and the pair of connection structures 503 and 506 in FIG. 5 is for illustration purposes only, and any type of connection technique may be applied here. The flexible OLED light-emitting panel 402 can be driven by wires or FPC boards embedded in the housing fixture 401 . Additionally, the elastic band 406 may include wires for driving the OLED devices, wireless communication devices, sensors, controllers and/or batteries. In another approach, the above-mentioned electronic components can be integrated into the substrate as long as it does not interfere with light emission.

In some embodiments, as shown in FIG. 6 , an OLED medical device 600 may include a plurality of flexible OLED light-emitting panels 602 and housing fixtures 601 (the connection structures are similar to those described above, and thus not shown in the figure). Here, the light-emitting side 605 exits the viewing plane, while the non-light-emitting side 604 enters the viewing plane. These flexible OLED light-emitting panels 602 can be driven independently, or can be driven in groups according to the light-emitting colors. This configuration produces devices with a small active area for high yield, and the advantages of flexible binning and sorting of high-performance OLED light-emitting panels. Additionally, if the device is bent in the x-direction, at least two light emitting areas may have a gap in the x-direction to facilitate small bending radii. In another solution, the flexible OLED light-emitting panel 602 may include a plurality of pixels, and these pixels may be driven independently or in groups according to the light-emitting colors. Another advantage of this pixelated light-emitting device is localized therapy. For example, when used in a weight loss belt, a person might only want to treat the side abs, in which case the entire device could be worn around his waist, but only the light-emitting pixels in contact with the sides of the waist would be turned on. This saves energy and extends the life of the device. In another scenario, the device could be wrapped around a wound, and only the pixels covering the wound area could be lit. What's more, this pixelated device enables multifunctional therapy. For example, the pixel 602 may also include at least one pixel emitting blue light with a peak wavelength between 400-500 nm, at least one pixel emitting green/yellow light with a peak wavelength between 500-580 nm, and at least one pixel emitting red light, Its peak wavelength is between 580-800nm. When wearing an OLED medical device, the green/yellow pixels can be turned on for wound healing, and the red pixels can be turned on to save weight. In some other embodiments, the pixel 602 may further include at least one pixel emitting light with a peak wavelength between 580-700 nm, and at least one pixel emitting light with a peak wavelength between 630-800 nm. Utilizing two red pixels helps achieve deep red or near-infrared emission while maintaining good device lifetime.

When in use, the OLED medical device can be worn on the user's abdomen, waist, thigh, arm, or any other desired treatment area, with the light-emitting side in close contact with the human skin. This is fundamentally different from Fraunhofer bracelets used as fashion jewelry or wearable displays used for viewing by the wearer (Pang, Proceedings of SPIE (2011) invited paper, 7956, 79560J-1.). Biosensors may be incorporated into the device, preferably in the housing fixture, to monitor the user's physical capabilities, such as lean fat mass ratio, weight change, glucose level, etc. In addition, wireless communication devices can also be integrated, making it possible to control the light emission and connect with other electronic devices, such as the user's phone, smart watch, computer, etc. The information collected by biosensors can be displayed on other devices, and the power or intensity of OLED medical devices can be dynamically controlled.

In another approach, the flexible OLED panel 702 may already include one or both of the front and rear cover films, and the housing fixture 701 may be an additional support film. Also, although drawn here as one component, OLED panel 702 may be pixelated. Holes 703 may include, but are not limited to, the eye area, nose area, and mouth area. When transitioning from a 2D sheet to a 3D conformal mask, there may be, for example, additional cutouts 704 to aid in the expansion of the mask. Note that the holes 703 and cutouts 704 are only examples here, and the design of such structures is well known to those skilled in the art. These cuts can be achieved by laser cutting. The connection structure is represented by earhook 705 in FIG. 7 . Alternatively, a headgear could be used as previously described, but not shown here. Here, the light-emitting side is 706, which exits the viewing plane, and the non-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, the two halves of the mirror OLED mask can be bonded together to form a single unit. The drive concept can be integrated in the connection structure or housing fastening as described above.

The eye mask 800 may comprise one flexible OLED panel 802, or the two light emitting regions 802 may come from two separate flexible OLED panels joined together in the middle. The two light emitting regions 802 can be electrically driven in parallel. Likewise, elastic band 803 may include wires or cables for external drives and batteries. A controller and wireless communication device can be further assembled in the eye mask to provide remote control. Similarly, flexible OLED panel 802 may also include RGB OLED pixels.

The OLED eye mask can provide the following possible medical effects, but not limited to:

1. When emitting white light, imitating sunlight to slow down jet lag;

2. When the luminous wavelength is >580nm, it promotes the sleep environment;

The OLED device is worn like a hat on the user's head with the light-emitting side facing the head, emitting a red or deep red light that is thought to stimulate hair growth. The housing fixture can be shaped like a hat. In another solution, an adhesive can be provided on the non-emitting side of the OLED light-emitting panel, so that it can be pasted inside a common hat beforehand. A user can wear the OLED-integrated hat while performing hair growth treatments without being noticed.
