Phosphorescent Component Placement for Powered-Down Display Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays do not generate images when powered down, limiting their ability to display advertisements or aesthetic images without consuming energy or battery power.
Innovation Solution
Incorporating a phosphorescent component between the cover lens and display module, activated by specific wavelengths of light, allowing images to be displayed even when the device is powered off, with customizable images stored in memory and activated by a processor before power-down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a conventional display is used without phosphorescent components, then the display can operate continuously with power, but it cannot display images when powered down
Solution Approach 1:
The display module activates the phosphorescent component before powering down, storing energy in the phosphorescent material. This preliminary action allows the phosphorescent component to continue emitting light and displaying images after the display is powered off, extending image display duration without continuous power consumption
Solution Approach 2:
The phosphorescent component acts as an intermediary between the display module and the external environment. It receives energy from the display module when powered on and converts it to sustained light emission when powered off, enabling image display during the powered-down state without direct power consumption
2Ease of manufacture
If the phosphorescent component is placed behind the display module, then it is protected during manufacturing, but the generated images are difficult to see
Solution Approach 1:
The patent changes the spatial dimension of the phosphorescent component placement from behind the display module to between the cover lens and display module. This dimensional change allows the phosphorescent component to be positioned in a location where generated images are easily visible through the cover lens while still being protected during manufacturing processes
3Illumination intensity
If the phosphorescent component is placed between the cover lens and display module, then images are easily visible, but the component may be damaged during manufacturing
Solution Approach 1:
The patent employs a protective film or adhesive layer as a flexible barrier between the phosphorescent component and the display module. This thin film protects the phosphorescent component from damage during manufacturing while allowing the component to remain positioned between the cover lens and display module for optimal image visibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Minimizes energy consumption by enabling image display without continuous power, while maintaining manufacturing protection for the phosphorescent component and allowing for customizable, multi-colored images.
Implementation Method 1
Incorporating a phosphorescent component between the cover lens and display module, activated by specific wavelengths of light, allowing images to be displayed even when the device is powered off

AI summary
In example implementations, a display is provided. The display includes a cover lens, a phosphorescent component, a display module and a processor. The phosphorescent component is located adjacent to the cover lens. The display module is located adjacent to the phosphorescent component opposite the cover lens. The processor is communicatively coupled to the display module to cause the display module to generate a desired image that activates corresponding portions of the phosphorescent component before the display is powered down.
