A textile-based organic light-emitting diode (OLED) for wearable devices can be used actively in various fields such as phototherapy and display. It could significantly impact integrated development. However, there have been no reports of color-tunable OLEDs based on textiles for therapeutic applications at multiwavelengths. This paper proposes a parallel-stacked OLED with wavelength-tunable properties through AC driving, utilizing advantages of wearable textiles. Through this, red and greenish blue were output from the stacked OLED to realize white light based on the textile platform, and the color adjustment from cool white to warm white was successfully achieved by controlling the wavelength. In addition, the parallel-stacked OLED exhibits the same tendency as a single OLED device, and it can be operated stably even at low voltage. Therefore, it demonstrates that it can be utilized for phototherapy through forward and reverse operation and optoelectronics engineering applications. It can also be applied as a display by outputting white light.

波长可调的基于纺织品的有机发光二极管，用于多功能可穿戴光医学应用和显示器，采用冷白光到暖白光


用于可穿戴设备的基于纺织品的有机发光二极管 （OLED） 可积极用于光疗和显示器等各个领域。它可能会对集成开发产生重大影响。然而，目前还没有关于基于纺织品的可调色 OLED 用于多波长治疗应用的报道。本文利用可穿戴纺织品的优势，通过交流驱动提出了一种具有波长可调特性的并联堆叠 OLED。通过这种方式，红色和绿蓝色从堆叠的 OLED 输出，实现基于纺织平台的白光，并通过控制波长成功实现了从冷白到暖白的颜色调整。此外，并联堆叠的OLED表现出与单个OLED器件相同的趋势，即使在低电压下也能稳定运行。因此，它表明它可以通过正向和反向操作以及光电子工程应用用于光疗。它也可以通过输出白光作为显示器应用。
