Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices using the RGB model perform sub-optimally in transparent or semi-transparent displays due to inadequate luminance and signal-to-noise ratio when superimposed with environmental light, leading to poor optical performance and inefficient power usage.
Innovation Solution
Employing alternative color primaries, such as cyan and amber, to form a color cord that enhances luminance and signal-to-noise ratio, allowing for improved visibility and power efficiency in transparent displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If RGB color model is used in transparent displays, then device complexity is reduced (standard color model), but optical performance deteriorates (luminance and signal-to-noise ratio)
Solution Approach 1:
The patent changes the color primary parameters from standard RGB to alternative combinations (e.g., cyan and amber). This parameter change optimizes the luminance output for transparent display conditions, achieving higher signal-to-noise ratio while maintaining manageable device complexity through systematic color space transformation.
2Device complexity
If RGB color model is used in transparent displays, then device complexity is reduced, but power efficiency deteriorates
Solution Approach 1:
By changing the color primary parameters to cyan and amber combinations, the system achieves more efficient light utilization. This parameter change reduces the energy required to achieve comparable luminance output, thereby improving power efficiency while maintaining reasonable device complexity through established color transformation methodologies.
3Ease of manufacture
If RGB color model is used in transparent displays, then ease of manufacture is maintained (standard model), but optical performance deteriorates (signal-to-noise ratio)
Solution Approach 1:
The patent introduces color transformation matrices and conversion algorithms as intermediary components that bridge standard RGB input with optimized cyan-amber output. This intermediary layer preserves manufacturing ease by accepting standard RGB data while transforming it into optically superior output, maintaining reliable signal-to-noise ratio through mathematical transformation rather than hardware complexity.
