技术领域Technical Field

本发明涉及一种OLED设备。更特别地，涉及一种OLED面膜及制备方法。The present invention relates to an OLED device and more particularly to an OLED mask and a preparation method thereof.

背景技术Background Art

近期研究显示一定波长的光照对健康有影响。例如，红光被认为会刺激胶原蛋白的生长从而消除细纹紧缩毛孔；黄光可以改善细胞内氧交换，引起皮肤细胞的再生；具有更高能量的蓝光可以杀死导致粉刺的卟啉类化合物(Kawada,Journal of Dermatologicalscience 30(2002)129-135)。这已经在美容院得到应用，一些疗程会使用LED光源对病患进行光照医疗(https://www.alibaba.com/product-detail/PDT-7-color-lights-led-photon_60738799145.html？spm＝a2700.details.maylikehoz.2.11ac5ecdx4Xz3g)。做成面罩形式的LED灯源可以用于家庭美容疗程，已经在市场上可以买到(https://detail.1688.com/offer/537712859216.html？spm＝a262fl.8287134.2826706.5.65c932c5Fou tTi)。在医疗界，深红或近红外的光源被显示可以杀死坏细胞如癌症细胞，同时生长好细胞如伤口愈合和生发功效(Dong,Photomedicine,OLED summit；Guo,Photodiagnosis and PhotodynamicTherapy 2015)。最近有新闻报道使用红光照射还可以帮助减肥，因为红光照射被发现可以缩小脂肪细胞(https://www.ledinside.com/news/2015/9/us_doctor_using_red_led_technology_to_aid_weight_lo ss)。另外，光照也会影响情绪。在US 4,777,937中介绍了一种可以发出单色光的头盔。加上一种粉色噪声的刺激，这种闪光的头盔可以产生一种超感官知觉效果帮助减压。尤其是，绿光和蓝光被认为可以帮助带来轻松感。Fraunhofer FEP展示了一个OLED手环，可以发出特定的波长帮助伤口愈合或者用于治疗忧郁症(见图2，http://www.osadirect.com/news/article/2152/fraunhofer-fep-hoslt-centre-and-vtt-develop-flexible-or ganic-electronics-for-wearable-applications/)。另外，研究人员发现增加或者减少日照可以帮助倒时差。例如，往东飞时，一般认为在清晨多照日光可以帮助调整旅行者的生物钟，而往西飞时，要在晚上多照日光(http://www.bbc.com/future/story/20140523-the-science-of-jet-lag)。然而，在一般的民航旅程中，都会调暗机舱灯光并拉下遮光板，所以是无法做到额外日照的。另一方面，夜间应该减少蓝光照射，尤其是在睡前。目前的通用照明一般使用LED或是荧光灯泡，其中带有很强的450纳米以下的蓝光波长，这会干扰正常睡眠。而OLED一般不含有深蓝光，是理想的睡眠光源。Recent studies have shown that certain wavelengths of light have an impact on health. For example, red light is believed to stimulate collagen growth, thereby eliminating fine lines and tightening pores; yellow light can improve intracellular oxygen exchange and cause skin cell regeneration; blue light with higher energy can kill porphyrin compounds that cause acne (Kawada, Journal of Dermatologicalscience 30 (2002) 129-135). This has been applied in beauty salons, and some treatments use LED light sources to treat patients with light therapy (https://www.alibaba.com/product-detail/PDT-7-color-lights-led-photon_60738799145.html?spm=a2700.details.maylikehoz.2.11ac5ecdx4Xz3g). LED light sources in the form of masks can be used for home beauty treatments and are already available on 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). Recently, there have been news reports that using red light can also help with weight loss, as red light exposure has been found to shrink fat cells (https://www.ledinside.com/news/2015/9/us_doctor_using_red_led_technology_to_aid_weight_loss). In addition, light exposure can also affect mood. US 4,777,937 introduces a helmet that emits monochromatic light. Combined with a pink noise stimulus, this flashing helmet can produce an extrasensory perception effect to help relieve stress. In particular, green and blue light are believed to help bring a sense of relaxation. Fraunhofer FEP has demonstrated an OLED bracelet that can emit specific wavelengths to help heal wounds 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/). In addition, researchers have found that increasing or decreasing sunlight can help with jet lag. For example, when flying east, it is generally believed that more sunlight in the early morning can help adjust the traveler's biological clock, while when flying west, more sunlight should be exposed to the evening (http://www.bbc.com/future/story/20140523-the-science-of-jet-lag). However, in general civil aviation journeys, the cabin lights are dimmed and the sunshades are pulled down, so additional sunlight is not possible. On the other hand, blue light exposure should be reduced at night, especially before going to bed. Current general lighting generally uses LED or fluorescent bulbs, which have strong blue light wavelengths below 450 nanometers, which can interfere with normal sleep. OLED generally does not contain deep blue light and is an ideal light source for sleep.

市场上已经有商业化的LED面罩。这些产品将LED芯片以阵列形式排在塑料面罩的背面(见图1)。LED是高强度的点光源，通常伴随发热。所以LED灯源一般会集成散热装置来带走热能，而且这些LED在阵列形式中使用时必须相隔一定距离排布以便散热。这导致了LED面罩的三个劣势。首先，这种面罩很厚很沉，因为考虑散热，他们必须加入散热装置，且为了安全必须与人脸有一定距离。这其中的一些面罩重达1.6公斤，戴在脸上是很不舒服的。第二，在阵列排布中，LED都是独立在某个位置，彼此之间存在间距，这导致发光不均匀。在美容治疗中，这样不均匀的光照可能带来肤色不均或者需要在不同区域多次治疗。最后，为了覆盖整张面部，需要使用大量LED，有时多达200个芯片。这增加了LED筛选，组装和维修的难度。There are already commercial LED masks on the market. These products use LED chips arranged in an array on the back of a plastic mask (see Figure 1). LEDs are high-intensity point light sources that usually generate heat. Therefore, LED light sources are generally integrated with heat sinks to remove heat energy, and these LEDs must be arranged at a certain distance when used in an array to dissipate heat. This leads to three disadvantages of LED masks. First, these masks are thick and heavy because they must have heat sinks to dissipate heat and must be kept a certain distance from the face for safety. Some of these masks weigh up to 1.6 kilograms and are very uncomfortable to wear on the face. Second, in the array arrangement, the LEDs are all located independently at a certain position and there is a gap between them, which leads to uneven light emission. In cosmetic treatments, such uneven light can lead to uneven skin tone or the need for multiple treatments in different areas. Finally, in order to cover the entire face, a large number of LEDs are required, sometimes up to 200 chips. This increases the difficulty of LED selection, assembly and maintenance.

相反，OLED是一个面光源，冷光源，不刺眼，而且具有轻薄的特质，使得它非常容易集成到柔性基板上。这使得OLED成为穿戴应用中理想选择。尽管如此，OLED面膜的制备和整个系统还是和LED面罩很不一样，这是因为两者的结构不同。另一方面，尽管各种形状和应用的柔性OLED照明(US 8,773,013,US 8,907,560)都有被展示过，很少有跟医疗功能相关的。在被用于医疗器械时，设计需要重新斟酌，而对OLED光源也有一定的要求。例如，对于一个面膜来说，基板材料和形状必须设计得越贴合表面越好。同时，取决于治疗目的，一定波长的光源会受到青睐，包括近红外谱段。即便在一些可穿戴的模型展示中，例如FraunhoferFEP的OLED手环，也更多的是装饰功能。而在我们的发明中，OLED是有医疗功能可穿戴或者靠近身体的灯源，同时我们也介绍了生产方法。In contrast, OLED is a surface light source, cold light source, non-glaring, and thin and light, making it very easy to integrate into flexible substrates. This makes OLED an ideal choice for wearable applications. Nevertheless, the preparation of OLED masks and the entire system are still very different from LED masks because of the different structures of the two. On the other hand, although flexible OLED lighting with 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. For example, for a mask, the substrate material and shape must be designed to fit the surface as closely as possible. At the same time, depending on the treatment purpose, light sources with certain wavelengths will be favored, including the near-infrared spectrum. Even in some wearable model demonstrations, such as FraunhoferFEP's OLED bracelet, they are more decorative. In our invention, OLED is a light source that can be worn or close to the body with medical functions, and we also introduce the production method.

柔性OLED是可穿戴或近身应用的关键。柔性OLED可以制备在各种柔性基板上，包括但不局限于，聚酰亚胺(PI)，聚对苯二甲酸乙二酯(PET)，聚萘二甲酸乙二醇酯(PEN),金属薄膜，织物，皮革，纸张等。对于面膜或眼膜这类的应用，器件希望能够完全贴合，所以常用基板为PI，PET，PEN，且厚度不超过0.3mm。当用于减肥带时，基板可以是PI，PET，PEN，皮革或织物，厚度不超过1mm。平坦层可以涂布在基板的制备面，即将涂布OLED的一面。基板可以在制备面涂布上薄膜封装层，或者在两面都涂上。一层阳极被沉积在基板上，并通过掩模版或者光刻板完成图形化。多层有机层会涂在已布有阳极的基板上，紧跟着是沉积阴极。另一种方案中，一层或多层功能层可以印刷在柔性基板上。阳极，有机层，阴极构成了一个基本的OLED器件。制备阳极，有机层，阴极的材料和方法为该领域内技术人员所熟知。薄膜封装层可以添加在阴极之上。薄膜封装层可以是一层有机层，或者更优选的是有机无机层交替组合。至少一对接触电极，包括至少一个阴极一个阳极，延伸于封装区域外以供外部电驱动。柔性印刷电路板(FPC)可以事先印刷出用于连接柔性OLED至外部驱动或内部连接多个OLED的电路。FPC板可以用导电胶电黏合到OLED接触电极上。将柔性OLED组装到FPC上可详见申请CN201810572632.3，以全文引用的方式并入。在一些实施例中，外部驱动可以通过在电接触上焊接电线实现。光提取层可以添加到柔性OLED的发光面。支撑膜可以添加到柔性OLED的非发光面。一个基本OLED器件加上封装层和外部驱动方案，配合可选的光扩散膜，FPC板以及支撑板，构成了一块OLED发光面板。柔性OLED的制造为该领域内技术人士所熟知，并不仅仅局限于上述描绘。Flexible OLEDs are key to wearable or near-body applications. 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 films, fabrics, leather, paper, etc. For applications such as facial masks or eye masks, the device is expected to fit perfectly, so commonly used substrates are PI, PET, PEN, and the thickness does not exceed 0.3mm. When used in slimming belts, the substrate can be PI, PET, PEN, leather or fabric, and the thickness does not exceed 1mm. The flat layer can be coated on the preparation side of the substrate, that is, the side where the OLED is to be coated. The substrate can be coated with a thin film encapsulation layer on the preparation side, or on both sides. An anode is deposited on the substrate and patterned using a mask or photolithography. Multiple organic layers are coated on the substrate with the anode, followed by the deposition of the cathode. In another solution, one or more functional layers can be printed on the flexible substrate. The anode, organic layer, and cathode constitute a basic OLED device. The materials and methods for preparing the anode, organic layer, and cathode are well known to those skilled in the art. A thin film encapsulation layer can be added on top of the cathode. The thin film encapsulation layer can be an organic 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 encapsulation area for external electrical drive. A flexible printed circuit board (FPC) can be pre-printed with circuits for connecting the flexible OLED to an external drive or internally connecting multiple OLEDs.

The assembly of the flexible OLED onto the FPC can be detailed in application CN201810572632.3, which is incorporated by reference in its entirety. In some embodiments, external drive can be achieved by welding wires on the electrical contacts. A light extraction layer can be added to the light-emitting surface of the flexible OLED. A support film can be added to the non-light-emitting surface of the flexible OLED. A basic OLED device plus an encapsulation layer and an external drive solution, with an optional light diffusion film, an FPC board, and a support board, constitute an OLED light-emitting panel. The manufacture of flexible OLEDs is well known to those skilled in the art and is not limited to the above description.

第一个实施例:First embodiment:

在第一个实施例中，我们公开了一种有医疗效果的OLED面膜。半张OLED面膜400在图4中画出。这半张面膜包括了柔性OLED发光面板410，空洞403漏出眼睛部分，一个可选的挂勾404用于将面膜挂在使用者耳朵上。柔性OLED发光面板410进一步包含了非发光区域401和发光区域402。非发光区域401可以包含基板的一部分，薄膜封装层的一部分，接触电极，FPC板的一部分，光提取层的一部分以及/或者支撑膜的一部分。该柔性OLED发光面板的形状要能代表人脸，可以是60％以上相似度，包括以下的一种或者多种组合，前额区域，眼睛区域，脸颊区域以及脖颈区域。在这里，“代表”指相同或大体形似，但并不要求轮廓或面积完全一致，这种情况包括但不局限于，轮廓形状相同但轮廓周长成比例伸缩，或轮廓形状有60％及以上相似度，或占有60％及以上面积。相似度(如上文所述60％)可以通过特定的图像处理识别软件或工具进行评估。发光区域402可以占整个柔性OLED发光面板的50％以上面积，更优化的选择中，占80％以上面积。这种面膜的图形设计为该领域技术人员所熟知，在这里一张二维的平面经切割后可以转换成三维面膜。特别的，为了允许柔性OLED发光面板的扩展，有必要在鼻翼(如切割线405)在下巴与脸颊区域(如切割线406)，以及在脖颈中线区域做额外的切割。柔性OLED发光面板410可以用激光切割成想要的形状。发光区域402可以在整个基板上都是连续的如图4所示。在另一种方案中如图5所示，发光区域402可以被划分成好几个区域，其中一部分411可以大致覆盖前额区域，而另一部分412覆盖脸颊区域。同样，图中所示仅为示意，任何其他图形都可以使用。发光区域的分隔可以通过分隔以下一层或多层实现，阳极层，有机层，阴极层。也可以通过分隔基板实现。在这种时候，支撑膜可以附加在所有独立的基板上以增加力学支持。多个发光区域402可以通过FPC板点连接到外部电源。多个发光区域可以并联连接或是单独驱动。发光区域402可以更进一步包含多个象素，其中至少一个象素发出峰值波长在400-500纳米的蓝光，一个象素发出峰值波长在500-580纳米的黄绿光，一个象素发出峰值波长在580-800纳米的红光。发出相同波长的多个象素可以是并联连接，而不同波长的象素单独驱动。通过使用RGB象素，可以实现光谱可调。OLED面膜400更进一步包括发光面408和不发光面409。在图4的示例中，发光面408指向纸面外，而不发光面409指向纸面内。In the first embodiment, we disclose an OLED mask with medical effects. A half OLED mask 400 is shown in FIG. 4 . The half mask includes a flexible OLED light-emitting panel 410, a hole 403 leaking out the eye part, and an optional hook 404 for hanging the mask on the user's ear. The flexible OLED light-emitting panel 410 further includes a non-luminous area 401 and a luminous area 402. The non-luminous area 401 may include a portion of a substrate, a portion of a thin film encapsulation layer, a contact electrode, a portion of an FPC board, a portion of a light extraction layer, and/or a portion of a supporting film. The shape of the flexible OLED light-emitting panel should be representative of a human face, which may be more than 60% similar, including one or more of the following combinations, forehead area, eye area, cheek area, and neck area. Here, "representative" means the same or roughly similar, but does not require the contour or area to be completely consistent. This includes, but is not limited to, the contour shape is the same but the contour perimeter is proportionally stretched, or the contour shape has a similarity of 60% or more, or occupies 60% or more area. The similarity (60% as described above) can be evaluated by specific image processing recognition software or tools. The light-emitting area 402 can occupy more than 50% of the area of the entire flexible OLED light-emitting panel, and in a more optimized option, more than 80% of the area. The graphic design of this mask is well known to technicians in the field, where a two-dimensional plane can be converted into a three-dimensional mask after cutting. In particular, in order to allow the expansion of the flexible OLED light-emitting panel, it is necessary to make additional cuts in the nose wing (such as cutting line 405), in the chin and cheek area (such as cutting line 406), and in the midline area of the neck. The flexible OLED light-emitting panel 410 can be cut into the desired shape by laser. The light-emitting area 402 can be continuous across the entire substrate as shown in Figure 4. In another embodiment, as shown in Figure 5, the light-emitting area 402 can be divided into several areas, of which a portion 411 can roughly cover the forehead area, and another portion 412 covers the cheek area. Again, the figure is only for illustration, and any other graphics can be used. The separation of the light-emitting area can be achieved by separating one or more of the following layers: the anode layer, the organic layer, and the cathode layer. It can also be achieved by separating the substrates. In this case, the support film can be attached to all independent substrates to increase mechanical support. Multiple light-emitting areas 402 can be connected to an external power supply through FPC board points. Multiple light-emitting areas can be connected in parallel or driven individually. The light-emitting area 402 can further include multiple pixels, at least one of which emits blue light with a peak wavelength of 400-500 nanometers, one pixel emits yellow-green light with a peak wavelength of 500-580 nanometers, and one pixel emits red light with a peak wavelength of 580-800 nanometers. Multiple pixels emitting the same wavelength can be connected in parallel, while pixels of different wavelengths are driven individually. By using RGB pixels, spectral tunability can be achieved. The OLED mask 400 further includes a light-emitting surface 408 and a non-light-emitting surface 409. In the example of Figure 4, the light-emitting surface 408 points outside the paper, and the non-light-emitting surface 409 points inside the paper.

该OLED面膜的另一半从发光面408看拥有与上述一半镜像的基板和发光面积。图6显示了还未贴合的成镜像的OLED面膜的两瓣400和500，它们贴合后将组成OLED面膜600。面膜的两瓣可以沿着贴合线601贴合，如图所示。这构成了一种共轭贴合，即沿着贴合线601的两瓣构成了镜像。贴合线601大致是人脸的中心线位置。注意图示的贴合线601仅为示例，其他种类的贴合线都可使用，例如沿着贴合线601分段的贴合。贴合线601不发光，属于不发光区域的一部分。贴合过程可以通过下述方法但不局限于下述方法实现，胶贴合，热贴合，压力贴合，缝合，夹合及其他。一个最终OLED面膜700从非发光面观察的三维效果图如图7a所示，包括了贴合线601，额外切割线405和406。一个最终OLED面膜710从发光面观察的二维效果图如图7b所示，它包括了两瓣OLED面膜400和500。为了实现良好的面部贴合效果，OLED面膜的二位平面设计至关重要，会需要增加额外的切割来帮助基板材料的扩张，以完成三维转换。这与制备一个简单的柔性OLED照明面板是很不同的策略。将两瓣二维面膜贴合也是一种新颖的做法。这种做法有多种好处：1，将发光面积缩小到至少两瓣时，生产良率会提高；2，与面部贴合良好度也随着使用两瓣面膜而改善；3，两瓣面膜很容易折叠成二维形式，降低了包装和运输成本。一条松紧带407可以取代耳部挂钩附加到OLED面膜720上并环绕使用者头部，如图8所示。松紧带407可以进一步集成导电电线来驱动OLED面膜，以及电池来驱动柔性OLED发光面板。另外，控制器和无线通讯器件也可以集成到松紧带中，这样使用者可以通过其他设备如手机，笔记本，电脑，智能手表等，控制发光面膜。The other half of the OLED mask has a substrate and a light-emitting area that are mirror images of the above half when viewed from the light-emitting surface 408. FIG. 6 shows two halves 400 and 500 of the mirror-image OLED mask that have not yet been bonded, which will form an OLED mask 600 after bonding. The two halves of the mask can be bonded along a bonding line 601, as shown. This constitutes a conjugate bonding, that is, the two halves along the bonding line 601 form a mirror image. The bonding line 601 is roughly the center line position of the face. Note that the bonding line 601 shown in the figure is only an example, and other types of bonding lines can be used, such as segmented bonding along the bonding line 601. The bonding line 601 does not emit light and is part of the non-luminous area. The bonding process can be achieved by the following methods but is not limited to the following methods, adhesive bonding, heat bonding, pressure bonding, stitching, clamping and others. A three-dimensional effect diagram of a final OLED mask 700 observed from the non-luminous side is shown in FIG. 7a, including the bonding line 601, additional cutting lines 405 and 406. A two-dimensional effect diagram of a final OLED mask 710 observed from the light-emitting surface is shown in FIG7b, which includes two OLED masks 400 and 500. In order to achieve a good facial fit, the two-dimensional plane design of the OLED mask is crucial, and additional cutting will be required to help the expansion of the substrate material to complete the three-dimensional transformation. This is a very different strategy from preparing a simple flexible OLED lighting panel. It is also a novel approach to fit the two-flap two-dimensional mask. This approach has multiple benefits: 1. When the light-emitting area is reduced to at least two lobes, the production yield will increase; 2. The good fit with the face is also improved with the use of a two-flap mask; 3. The two-flap mask is easily folded into a two-dimensional form, reducing packaging and transportation costs. An elastic band 407 can be attached to the OLED mask 720 instead of the ear hook and wrapped around the user's head, as shown in FIG8. The elastic band 407 can further integrate conductive wires to drive the OLED mask, and batteries to drive the flexible OLED light-emitting panel. In addition, the controller and wireless communication device can also be integrated into the elastic band, so that the user can control the luminous mask through other devices such as mobile phones, notebooks, computers, smart watches, etc.

在一些实施例中，OLED面膜不需把眼部区域切出来，如图9a所示。在另一些实施例中，眼部区域可以部分切出来(如901)，如图9b所示。这种配置可以提供仅在需要时治疗眼部的灵活性。另一些实施例中，面膜可以进一步包含脖颈区域，如图10所示。这里，覆盖脖颈区域的柔性OLED发光面板可以是半张面膜的延伸，或者可以是独立的围脖。注意，图10只是该种应用中的一种示例，其他图形只要能覆盖60％的脖颈区域都可以使用。In some embodiments, the OLED mask does not need to cut out the eye area, as shown in Figure 9a. In other embodiments, the eye area can be partially cut out (such as 901), as shown in Figure 9b. This configuration can provide the flexibility to treat the eyes only when needed. In other embodiments, the mask can further include a neck area, as shown in Figure 10. Here, the flexible OLED light-emitting panel covering the neck area can be an extension of half of the mask, or it can be an independent neckband. Note that Figure 10 is only an example of this application, and other graphics can be used as long as they can cover 60% of the neck area.

另外，两瓣OLED面膜也可以呈现互补形状。图13展示了一个示例，其中一个上半部面膜421和一个下半部OLED面膜422可以通过贴合线423进行组合形成完整OLED面膜420。在这个示例中，这两瓣OLED面膜并没有呈现镜像，而是在贴合线部位呈现互相咬合。In addition, the two OLED masks can also present complementary shapes. FIG. 13 shows an example in which an upper mask 421 and a lower mask 422 can be combined through a bonding line 423 to form a complete OLED mask 420. In this example, the two OLED masks do not present a mirror image, but rather interlock at the bonding line.

该OLED面膜可以提供如下可能的治疗效果，但不局限于：The OLED mask can provide the following possible therapeutic effects, but not limited to:

1.在发光波长>580nm时，刺激胶原蛋白生长，增加抗疲劳，激发细胞新陈代谢；1. When the luminous wavelength is >580nm, it stimulates collagen growth, increases anti-fatigue, and stimulates cell metabolism;

2.在发光波长<500nm时，消除粉刺炎症：抗菌，消炎，再生，抑制皮脂分泌，有抗衰老效果；2. When the luminous wavelength is less than 500nm, it can eliminate acne inflammation: antibacterial, anti-inflammatory, regenerative, inhibit sebum secretion, and have anti-aging effects;

3.在发光波长在500–580nm时，平衡色素，减缓细纹，给衰老的肌肤补充营养，加速伤口愈合；3. When the luminous wavelength is 500-580nm, it balances pigments, slows down fine lines, replenishes nutrients to aging skin, and accelerates wound healing;

4.在发白光时，仿日光减缓时差反应。4. When emitting white light, it imitates sunlight to alleviate jet lag.

第二个实施例:Second embodiment:

接下来，我们公开一种有医疗效果的OLED眼罩。图11显示了该眼罩的一种示例。OLED眼罩800包含一个基底801，两个发光区域802，以及一条松紧带803。OLED眼罩800进一步包含发光面808和不发光面809。如图11所示，发光面808指向纸面外，不发光面809指向纸面内。基底801和两个发光区域802可以是同一块柔性OLED发光面板的组成部分。在另一种方案中，两块发光区域802可以来自两块独立的柔性OLED发光面板。在这种时候，两块柔性OLED发光面板可以沿着贴合线804以共轭方式贴合，当从发光面808方向看时两块面板图形成镜像。这两块发光区域802可以是并联连接。同样，松紧带803集成了用于外部驱动的线缆和电池。控制器和无线通讯器件可以进一步集成在眼罩中以便远程控制。类似的，发光区域可以包含RGB象素。Next, we disclose an OLED eye mask with medical effects. FIG11 shows an example of the eye mask. The OLED eye mask 800 includes a substrate 801, two light-emitting areas 802, and an elastic band 803. The OLED eye mask 800 further includes a light-emitting surface 808 and a non-light-emitting surface 809. As shown in FIG11, the light-emitting surface 808 points outside the paper, and the non-light-emitting surface 809 points inside the paper. The substrate 801 and the two light-emitting areas 802 can be components of the same flexible OLED light-emitting panel. In another embodiment, the two light-emitting areas 802 can come from two independent flexible OLED light-emitting panels. In this case, the two flexible OLED light-emitting panels can be conjugated along the bonding line 804, and the two panels are mirrored when viewed from the direction of the light-emitting surface 808. The two light-emitting areas 802 can be connected in parallel. Similarly, the elastic band 803 integrates cables and batteries for external drive. The controller and wireless communication device can be further integrated in the eye mask for remote control. Similarly, the luminous area can contain RGB pixels.

该OLED眼罩可以提供如下可能的医疗效果，但不局限于：The OLED eye mask can provide the following possible medical effects, but not limited to:

1.在发白光时，仿日光减缓时差反应；1. When emitting white light, it imitates sunlight to alleviate jet lag;

2.在发光波长>580nm时，促进睡眠环境；2. When the luminous wavelength is >580nm, it promotes a sleeping environment;

6.在发光波长在500–580nm时，平衡色素，减缓细纹，给衰老的肌肤补充营养，加速伤口愈合。6. When the luminous wavelength is between 500-580nm, it balances pigments, slows down fine lines, replenishes nutrients to aging skin, and accelerates wound healing.

第三个实施例:The third embodiment:

在该实施例中，我们公开了一种OLED面膜，其不需要两半单独的柔性OLED。如图12a所示，OLED面膜100具有发光区域110和不发光区域111。发光区域110包括OLED器件。OLED器件还可以包括多个像素，并且类似地，像素可以发射红色，绿色和蓝色。切口105和108用于暴露鼻子和嘴部区域，而切口101,102,106和107用于在3D转换期间进行扩展。注意，可以引入额外的切口以辅助3D转换，并且本领域技术人员都具有设计这个的知识。耳钩109附接到面膜的两侧。或者，可以如前所述应用头带，但这里没有画出。OLED面膜100没有暴露眼部区域，适于在休息，睡眠或眼睛治疗期间佩戴。或者，如图12b所示，可以部分地切割出眼睛区域，其中额外的切口103和104被添加到OLED面膜200中的眼睛区域。OLED面膜200包括不同的发光区域210和不发光区域211。在另一个示例中，OLED面膜300(参见图12c)包括发光区域310和不发光区域311，其中通过切口303和304实现了眼睛区域被完全切除。当佩戴者需要在治疗期间做其他事时，这种面膜更受青睐。In this embodiment, we disclose an OLED mask that does not require two separate halves of a flexible OLED. As shown in FIG. 12a, the OLED mask 100 has a light-emitting area 110 and a non-light-emitting area 111. The light-emitting area 110 includes an OLED device. The OLED device may also include multiple pixels, and similarly, the pixels may emit red, green, and blue. Cutouts 105 and 108 are used to expose the nose and mouth areas, while cutouts 101, 102, 106, and 107 are used to expand during 3D conversion. Note that additional cutouts may be introduced to assist in 3D conversion, and those skilled in the art have the knowledge to design this. Ear hooks 109 are attached to both sides of the mask. Alternatively, a headband may be applied as described above, but is not drawn here. The OLED mask 100 does not expose the eye area and is suitable for wearing during rest, sleep, or eye treatment. Alternatively, as shown in FIG. 12b, the eye area may be partially cut out, where additional cutouts 103 and 104 are added to the eye area in the OLED mask 200. The OLED mask 200 includes different light-emitting areas 210 and non-light-emitting areas 211. In another example, the OLED mask 300 (see FIG. 12c ) includes a light-emitting area 310 and a non-light-emitting area 311, wherein the eye area is completely cut off by cutouts 303 and 304. This mask is more preferred when the wearer needs to do other things during treatment.
