Hybrid E-Paper Display with Static Frame and Dynamic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic paper (e-paper) display technologies lack the ability to effectively communicate dynamic information and secure data through a combination of static and dynamic pattern elements, limiting their application in marketing, security, and identification.
Innovation Solution
A display device comprising a non-imagable support frame with a passive e-paper display portion, where a writing unit selectively writes a second pattern element onto the e-paper to be juxtaposed with a first pattern element, allowing for the communication of various types of information and security features, using an imaging unit that can erase and write via airborne charges, controlled by a processor and memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If e-paper display technology is used, then flexibility and durability are improved, but the ability to communicate dynamic information and secure data is limited
Solution Approach 1:
The patent combines static non-imagable support frame with dynamic e-paper display portion to create a hybrid system that maintains the flexibility and durability of e-paper while adding the capability to display dynamic information through selective imaging
Solution Approach 2:
The patent introduces dynamic capability to the otherwise static e-paper display by enabling selective writing and erasing of pattern elements on the e-paper portion, allowing the display to adapt and change information dynamically while preserving the underlying flexible and durable substrate
2Stability of the object's composition
If static pattern elements are used on support frame, then structural stability is improved, but information communication capability deteriorates
Solution Approach 1:
The patent segments the display into two distinct portions: a static non-imagable support frame that provides structural stability and a dynamic e-paper display portion that enables information communication, allowing each component to fulfill its specific function optimally
3Adaptability or versatility
If imaging unit is added to write on e-paper, then dynamic information display is improved, but device complexity increases
Solution Approach 1:
The patent extracts the imaging functionality into a separate, controllable unit that can selectively write and erase pattern elements on the e-paper display portion, enabling dynamic information display while keeping the core e-paper structure simple and manageable
