Adaptive Display Switching Between Reflective and Transmissive Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signs and displays are often designed for worst-case viewing scenarios, failing to provide optimal visibility across varying conditions such as day and night, and are prone to malfunction due to damage or component failure, which can compromise safety and functionality.
Innovation Solution
A color-changing display system that includes a housing, a light panel, and a color display panel, capable of operating in reflective, transmissive, and transflective modes, with a processor and computer memory to selectively activate the display for alerts, and features a smart panel with switchable color particles and a gel filter for enhanced visibility and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the sign is designed for night-time viewing, then the sign provides good visibility at night, but the sign does not provide optimal viewing during the day
Solution Approach 1:
The display system dynamically switches between transmissive mode (for night viewing) and reflective mode (for daytime viewing) based on ambient lighting conditions. The controller automatically adjusts the operational mode to optimize visibility across varying environmental conditions, transforming a static display into an adaptive system.
Solution Approach 2:
The display system incorporates multiple operational modes (transmissive, reflective, and transflective) within a single device, enabling it to function effectively across diverse viewing conditions. This multi-functionality allows the same display to serve both night-time and daytime viewing requirements without requiring separate systems.
2Adaptability or versatility
If the display uses a single operational mode, then the device complexity is reduced, but the display cannot adapt to different viewing conditions
Solution Approach 1:
The patent combines transmissive and reflective display technologies into a single integrated system. The display assembly includes both transmissive components (light source, transmissive panel) and reflective components (reflective panel, mirror), which work together under the control of a single controller to provide multi-mode operation without requiring entirely separate systems.
3Illumination intensity
If the display operates in transmissive mode only, then the display provides good visibility in dark conditions, but the display consumes excessive energy and is not suitable for daytime use
Solution Approach 1:
The system dynamically adjusts its operational mode based on ambient light conditions. In bright environments, it switches to reflective mode which requires minimal or no active illumination, thereby dramatically reducing energy consumption. In dark environments, it activates transmissive mode to provide necessary visibility, optimizing the balance between visibility and energy usage.
4Illumination intensity
If the sign is designed with high brightness for night visibility, then the sign is visible at night, but the sign causes glare and is difficult to view during the day
Solution Approach 1:
The display dynamically adjusts its brightness and operational mode based on ambient lighting conditions. During daytime, it switches to reflective mode where the display reflects ambient light rather than emitting high-intensity light, eliminating glare. At night, it activates transmissive mode with controlled brightness to provide visibility without causing excessive glare, thus adapting to prevent harmful effects in different conditions.
