TOLED Display Hinge Installation with Electrochromic Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bonding methods for TOLED displays on architectural glass are permanent, making maintenance and replacement difficult due to the shorter lifespan of TOLEDs compared to architectural glass, and lack transparency control.
Innovation Solution
A system and method for semi-permanent installation of TOLED displays with transparency control, using a TOLED panel coupled with electrochromic glass and hinge assemblies for easy rotation and removal, allowing for aesthetic and functional flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent bonding methods are used to install TOLED displays on architectural glass, then the installation is secure and stable, but the display cannot be easily removed or replaced for maintenance
Solution Approach 1:
The display system is divided into separable components: the TOLED display module and the architectural glass substrate. The hinge assembly creates a segmented connection that allows the display to be detached from the glass for maintenance while maintaining a stable installed position during normal operation.
Solution Approach 2:
The hinge assembly introduces dynamic functionality to the installation system, enabling the display to rotate between different positions (installed, removed, maintenance positions) while maintaining secure attachment during normal use. This dynamic connection resolves the contradiction between permanent stability and ease of removal.
2Ease of manufacture
If TOLED displays are directly bonded to architectural glass, then the installation is simple, but the display cannot be easily maintained or replaced due to the shorter lifespan of TOLEDs compared to glass
Solution Approach 1:
The system segments the TOLED display from the architectural glass structure through the hinge assembly, creating independent replaceable modules. This allows the shorter-lived TOLED component to be maintained or replaced without affecting the permanent glass infrastructure.
Solution Approach 2:
The hinge assembly enables the TOLED display to be discarded (removed) and recovered (reinstalled or replaced) easily, addressing the lifespan mismatch between TOLEDs and architectural glass. The display can be taken down for maintenance and put back up without damaging the glass structure.
3Reliability
If current bonding methods are used, then the display is securely attached, but removal processes are risky and may damage the display or glass
Solution Approach 1:
The hinge assembly provides a dynamic, controlled detachment mechanism that eliminates the risk of damage during removal. The display can be safely taken down by operating the hinge mechanism, avoiding the harmful effects associated with forced removal from permanent bonds.
Solution Approach 2:
The hinge assembly acts as an intermediary component between the TOLED display and the architectural glass, providing a controlled interface for attachment and detachment. This intermediary mechanism prevents direct contact damage that would occur with permanent bonding methods during removal.
4Ease of manufacture
If TOLED displays are installed without transparency control, then the installation is simpler, but the visibility and aesthetic flexibility are limited
Solution Approach 1:
The display system is designed with multi-functionality, combining the TOLED display with electrochromic glass that provides adjustable transparency control. This universal design allows the same system to adapt to different visibility requirements and aesthetic preferences without requiring separate installation systems.
Solution Approach 2:
The electrochromic glass provides dynamic transparency control, allowing the display to adjust its opacity in response to different conditions. This dynamic feature enhances adaptability while maintaining a relatively simple integrated installation structure.

AI summary
A system and method for removable or semi-permanent installation of a transparent organic lighting diode (TOLED) display with transparency control are disclosed. In one embodiment, the system includes a TOLED display that includes a TOLED panel with a front side and a back side, a cover glass coupled to the front side of the TOLED panel, and an electrochromic (EC) glass coupled to the back side of the TOLED panel to provide transparency control of the TOLED panel. The system further includes a top hinge assembly and a bottom hinge assembly used to rotatably couple the TOLED display to a support structure to facilitate rotation of the TOLED display to different positions and to provide relatively easy removal of the TOLED display.
