Solution Overview

Problem

Current transparent displays, such as LCD and OLED, are not suitable for video applications due to high resistivity in ITO layers, limiting conductivity and causing slow switching circuits, while flexible displays are limited in deformability and prone to wear, and stretchable electronics reduce available space for high resolution.

Innovation Solution

A deformable display system with flexible circuit boards, local pixel drivers, and stretchable conducting paths, allowing for high-resolution images by reducing unnecessary circuit board material and using multiplexing to minimize connections, integrated with additional functionalities like photovoltaic cells and sensors, and real-time color calibration to adjust color perception based on content and viewing angle.
