Dual-Substrate Display Apparatus for Simultaneous Mirroring and Image Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses that combine mirroring and display functions using semi-transmission mirrors suffer from reduced light transmission and reflectance, limiting their ability to effectively display images on both surfaces while maintaining a high reflection property.
Innovation Solution
A dual-layer display apparatus with first and second substrates, each featuring display and non-display regions, reflection members, driving circuits, and insulation layers, allowing for independent image display and mirroring on both surfaces without degrading reflection properties, using reflection and transmissive materials to optimize light transmission and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If semi-transmission mirrors are used to combine mirroring and display functions, then both functions can be performed, but light transmission and reflectance are reduced
Solution Approach 1:
The display apparatus is divided into two separate substrates: a first substrate for display function and a second substrate for mirroring function. This segmentation allows each substrate to be optimized for its specific function without compromising performance - the first substrate can have high light transmission for display while the second substrate can have high reflectance for mirroring.
Solution Approach 2:
The patent transitions from a single-substrate design to a dual-substrate stacked configuration. By adding the dimension of substrate layering, the system achieves both display and mirroring functions simultaneously without the performance degradation that occurs when attempting to combine both functions in a single layer.
2Adaptability or versatility
If images are displayed on both surfaces, then dual display function is achieved, but reflection property deteriorates
Solution Approach 1:
Different regions of the dual-substrate structure are assigned different optical properties. The first substrate is designed with high transmittance characteristics for display purposes, while the second substrate is designed with high reflectance characteristics for mirroring purposes. This local optimization of material properties ensures that each function operates at peak performance.
Solution Approach 2:
The patent creates a mirrored copy structure where the second substrate acts as a reflection of the first substrate's display content. By using a separate substrate for the mirrored image, the original display quality is preserved while enabling simultaneous mirroring 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
The apparatus achieves simultaneous image display and mirroring on both surfaces without compromising reflection quality, enhancing both display and mirroring functions by optimizing the placement and materials of reflection members and insulation layers.
Implementation Method 1
An image may be displayed on a side of the second substrate by light emitted from the first display device, and an image may be displayed on a side of the first substrate by light emitted from the second display device
Implementation Method 2
a first reflection member that is disposed between the first substrate and the first display device and overlaps the first display device
