Solution Overview
Problem
Conventional display devices lack the ability to efficiently direct electromagnetic radiation in predetermined directions, limiting their aesthetic and practical applications, such as in transparent substrates where visibility and information display are desired.
Innovation Solution
A display device comprising a substrate with radiation-directing features that are configured to redirect electromagnetic radiation, such as visible light, UV, or IR, within the substrate towards a viewing surface, using techniques like laser-induced refractive index changes or localized stress patterns, allowing for controlled light redirection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional display devices use transparent substrates, then visibility through the substrate is maintained, but the ability to direct electromagnetic radiation in predetermined directions is lost
Solution Approach 1:
The substrate is segmented by incorporating discrete radiation-directing features (such as microlenses, prisms, or reflective particles) distributed within the transparent material. Each feature acts as an independent element that redirects electromagnetic radiation along specific paths, enabling directional control while preserving overall substrate transparency.
Solution Approach 2:
The transparent substrate exhibits non-uniform optical properties through the incorporation of radiation-directing features at specific locations. These features create localized regions with different refractive indices or reflective properties, enabling predetermined direction control of electromagnetic radiation only in specific areas while maintaining uniform transparency in other regions.
2Adaptability or versatility
If radiation-directing features are incorporated in the substrate, then electromagnetic radiation can be directed in predetermined directions, but the complexity of the device increases
Solution Approach 1:
The radiation-directing features are integrated directly into the substrate material itself, merging the functions of the substrate (providing structural support and transparency) with the radiation-directing features (controlling electromagnetic radiation paths). This eliminates the need for separate components and reduces overall device complexity.
Solution Approach 2:
The substrate itself serves dual purposes: maintaining structural integrity and transparency while simultaneously directing electromagnetic radiation through its incorporated features. The substrate structure is designed to inherently guide radiation along predetermined paths without requiring additional external directing mechanisms.
3Loss of information
If radiation-directing features are used to display images on transparent substrates, then visibility and information display are enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The desired image or information is created by arranging radiation-directing features in specific patterns that replicate or encode the intended visual information. These features act as optical elements that redirect light to form the displayed image, allowing information to be conveyed through the transparent substrate when illuminated.
