Exploring New Possibilities in Beauty Devices with Thin and Flexible OLED

We believe that the thinness and flexibility of Nippon Shokubai’s OLED light source will contribute to the next stage of innovation in beauty devices. It allows for easier handling and more uniform light emission, enhancing the overall user experience.
Nippon Shokubai’s Ultra-thin, Flexible OLED Light Source
Our OLED Light Source is thinner than paper, offering a breakthrough in design freedom for next-generation beauty devices.
With this ultra-thin, flexible OLED light source, explore new solutions.
Key Features
Feature 1: Thinness

Our OLED light source is approximately 0.1 mm thick, enabling an ultra-thin, lightweight, and compact design — ideal for masks and wearable beauty devices.
Feature 2: Flexibility

Its high flexibility allows it to conform closely to the contours of the skin, enabling efficient and even light irradiation.
Bending Radius

| Bending Radius(inward) | 4 mm |
| Bending Radius(outward) | 4 mm |
Feature 3: Uniform Light Emission

Surface-emitting design enables uniform and gentle light distribution across the skin. Unlike point light sources, our OLEDs achieve this without a diffuser.
Emission Area Ratio (Standard Samples)

| Shape | Emission Area | Light Source Size | Emission Area Ratio |
|---|---|---|---|
| Square | 20 mm × 20 mm | 25 mm × 28 mm | 57% |
| Square | 50 mm × 50 mm | 56 mm × 59 mm | 75% |
| String-like | 0.5 mm × 135 mm | 5 mm × 150 mm | 9% |
| Ribbon-like | 10 mm × 150 mm | 16 mm × 158 mm | 59% |
Feature 4: Minimal Heat Emission
Owing to its high luminous efficiency, Nippon Shokubai’s OLED Light Source generates minimal thermal energy. Beauty devices utilizing our OLED technology are expected to minimize thermal stress on the skin and contribute to a more comfortable user experience.
