Highly Flexible and Efficient Fabric Based Organic Light-Emitting Devices for Clothing-Shaped Wearable Displays

Journal: Scientific Reports

Publication date: 2017.07.25

Summarized by Seongmin Park

 

– Methods to achieve actual clothing-shaped information displays

  1. Attaching a display panel onto a piece of clothing → Flexibility decreases
  2. Fabricating of light emitting fiber → Low emission performance
  3. Fabricating an information display onto a fabric → Best choice

– Novel Concept

v. Spin coating of the silane-based film on fabric (Fig. 1, 2)
