AI Technical Summary

Technical Problem

Existing optoelectronic devices are difficult to adapt to various curved surfaces, especially since traditional flexible substrates have insufficient water and oxygen barrier properties, leading to manufacturing difficulties and increased costs. At the same time, traditional manufacturing technologies are difficult to adapt to complex curved surfaces.

Method used

A flexible substrate made of high-temperature resistant polymer material is combined with paper cutting or origami folding techniques to form a three-dimensional optoelectronic device. The light-emitting element is independently controlled by using Origami or Kirigami patterns and is fixed to a curved surface by adhesives or machinery.

Benefits of technology

It achieves good adaptability to complex curved surfaces and independent light emission control, improves the water and oxygen protection performance of the device, and reduces manufacturing difficulty and cost.
