Sensor-Based Transparent Display Color Correction for Ambient Tint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display devices exhibit a yellowish tint due to the organic film and cathode, and the tint changes with variations in illuminance and color temperature of external light sources, affecting visibility and application range.
Innovation Solution
A transparent display device equipped with an illuminance sensor that calculates background conversion illuminance, allowing for correction of display input images in non-display regions based on measured illuminance and color characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If transparent display panel is used, then transparency is achieved, but yellowish tint appears due to organic film and cathode
Solution Approach 1:
The patent applies color correction by analyzing the spectral characteristics of the transparent display panel and compensating for the yellowish tint through color temperature adjustment and spectral balancing techniques
Solution Approach 2:
The patent changes operational parameters including drive current, pulse width modulation duty cycle, and color mixing ratios to adjust the spectral output and reduce the yellowish tint while maintaining transparency
2Illumination intensity
If transparent display panel is used, then visibility is improved, but tint changes with external lighting conditions
Solution Approach 1:
The patent implements feedback control by measuring the spectral characteristics of the transparent display panel under different lighting conditions and dynamically adjusting drive parameters to maintain consistent tint and visibility
Solution Approach 2:
The patent makes the display system dynamic by continuously adapting color temperature, brightness, and spectral composition in response to changing ambient lighting conditions to maintain optimal visibility and color consistency
3Adaptability or versatility
If illuminance sensor and image correction are added, then visibility and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent enables self-service operation by implementing automatic spectral analysis and correction algorithms that continuously monitor and adjust display characteristics without requiring manual intervention or complex external control systems
Solution Approach 2:
The patent achieves multi-functionality by integrating illuminance sensing, spectral analysis, and image correction capabilities into a unified control system that handles multiple functions through coordinated processing rather than separate dedicated components
