Solution Overview
Problem
Existing window systems fail to efficiently utilize the window surface area for media display while maintaining visibility and protecting the display from environmental factors like UV irradiation and heat, and do not effectively integrate augmented reality and shading options.
Innovation Solution
A display construct integrated with a tintable window, comprising a transparent organic light-emitting diode (TOLED) display and an electrochromic device, allowing for media display, augmented reality, and shading, with a fastener system for reversible mounting and control mechanisms for tint adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transparent display is installed on the window surface, then media display capability is improved, but the display is exposed to environmental factors (UV irradiation, heat) that cause degradation
Solution Approach 1:
An electrochromic device is positioned between the transparent display and the external environment. This intermediary component controls light transmission and provides a tinted backdrop when activated, protecting the display from UV irradiation and heat while allowing the display to function. The electrochromic device acts as a protective barrier that can be adjusted between transparent and tinted states.
Solution Approach 2:
The electrochromic device changes its optical parameters (transparency to tinting) in response to environmental conditions or user control. When the display is in use, the electrochromic device remains transparent. When protection is needed or when the display is not active, the electrochromic device transitions to a tinted state, reducing UV exposure and heat while maintaining the structural integrity of the window system.
2Illumination intensity
If a tinted backdrop is used for media display, then display contrast is improved, but visibility through the window is reduced
Solution Approach 1:
The electrochromic device provides dynamic control over the backdrop tinting. The system can switch between transparent and tinted states based on display activity, environmental conditions, or user preference. When media display is active, the electrochromic device provides a tinted backdrop for enhanced contrast. When the display is inactive or when external visibility is prioritized, the electrochromic device transitions to a transparent state, allowing clear viewing through the window.
3Productivity
If the window surface is used for media display, then space utilization is improved, but the window's primary function of providing external view is compromised
Solution Approach 1:
The system dynamically switches between display mode and viewing mode. The electrochromic device and transparent display work together to provide a tinted backdrop when media display is active, enhancing display contrast. When external viewing is desired, the electrochromic device transitions to a transparent state, allowing clear viewing through the window while the transparent display can be turned off or set to a transparent state, thus maintaining the window's primary function.
Solution Approach 2:
The window system is designed to perform multiple functions: it can serve as a transparent display for media playback, as a clear viewing window for external scenery, and as a controllable backdrop for enhanced display contrast. The electrochromic device enables the window to adapt between these different functions based on user needs and environmental conditions, making the system universally applicable for both display and viewing purposes.
