Mirror Display Reflecting Layer Openings for Clear Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirror displays with translucent mirrors face challenges in combining reflected images with displayed content due to low reflectance and reduced transmittance, making it difficult to clearly view both images simultaneously.
Innovation Solution
A display device configuration featuring a micro LED display with a light reflecting layer and transparent conductive layer, where the light reflecting layer has a mirror surface and openings overlapping the light emitting elements, allowing for independent reflection and emission areas to prevent light reflection from decreasing the luminance of displayed images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a translucent mirror is used in a mirror display, then the display can function as both a mirror and a display device, but the reflectance is lower than a reflecting mirror making it difficult to add reflected images with displayed content
Solution Approach 1:
The mirror surface is segmented into multiple regions: a first region with high reflectance for reflecting external light, and a second region with low reflectance for allowing light from the light emitting element to pass through. This segmentation enables the mirror display to simultaneously achieve high reflectance for mirror function and light transmission for display function without compromising either.
2Adaptability or versatility
If a translucent mirror is used in a mirror display, then the display can function as both a mirror and a display device, but the transmittance of the displayed image is lowered by the translucent mirror
Solution Approach 1:
The mirror surface is divided into a first region that reflects light and a second region that transmits light. The light emitting element is positioned to emit light through the second region, which has low reflectance and high transmittance characteristics. This allows the displayed content to pass through with minimal obstruction while the first region maintains mirror functionality.
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
This configuration enables clear viewing of both reflected and displayed images without compromising luminance, as the light reflecting layer effectively reflects external light while allowing light from the micro LEDs to be emitted without interference.
Implementation Method 1
a plurality of light emitting elements mounted on the base layer
Implementation Method 2
a light reflecting layer provided above the flat surface and including a mirror surface located on an opposite side of a surface facing the flat surface and a plurality of openings overlapping the light emitting elements
