Deformable Transparent Display for Flexible Electronics
Here’s PatSnap Eureka !
Summary
Problems
Current transparent displays, such as LCD and OLED, suffer from limited flexibility, slow switching circuits due to high resistivity, and low resolution in stretchable electronics, making them unsuitable for video applications and prone to wear and tear from frequent bending.
Innovation solutions
A deformable display system with a flexible circuit board, embedded LEDs, and local pixel drivers, combined with stretchable conducting paths and selective removal of non-pixel areas, allows for high-resolution, real-time deformation without losing transparency, and incorporates additional functionalities like photovoltaic cells and sensors.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If ITO layers are used for transparency, then optical transparency is achieved, but switching speed becomes slow due to high resistivity
Why choose this principle:
The patent removes the ITO layer from the display structure entirely, replacing it with an organic transparent conductor. This extraction of the problematic component eliminates the resistivity issue while maintaining transparency, directly resolving the contradiction between optical transparency and switching speed.
Principle concept:
If ITO layers are used for transparency, then optical transparency is achieved, but switching speed becomes slow due to high resistivity
Why choose this principle:
The patent changes the material parameter from inorganic ITO to organic transparent conductor, fundamentally altering the electrical properties while preserving optical properties. This parameter change enables both high transparency and fast switching by using materials with inherently lower resistivity.
