Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional depth-fused 3D display devices suffer from low light utilization ratios due to the use of liquid crystal display panels, which require time-division operation and complex synchronization, leading to reduced viewing experience and increased material costs.
Innovation Solution
A depth-fused 3D display device comprising a first transparent organic light-emitting display panel and a second reflective or transparent OLED panel, separated by a circular polarizer, allowing simultaneous display and blending of foreground and background images without the need for a synchronization controller, thereby improving light utilization and simplifying the device structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If liquid crystal display panels are used in depth-fused 3D display device, then the device can display 3D images, but the light utilization ratio decreases to about 5% due to time-division operation and multiple light passages
Solution Approach 1:
The patent replaces the liquid crystal display panels with organic light-emitting display panels that do not require time-division operation. This substitution eliminates the need for synchronization controllers and complex switching mechanisms, allowing both display panels to operate simultaneously and improve light utilization ratio from 5% to 30% or more.
Solution Approach 2:
The patent enables continuous display operation where the first display panel displays foreground images and the second display panel displays background images simultaneously without interruption. This continuous operation eliminates the time-division switching mechanism and improves both light utilization ratio and viewing experience.
2Illumination intensity
If two liquid crystal display panels are stacked side by side, then the device can provide depth fusion, but the light transmissivity becomes very low because only a little part of light from the light source can reach the viewer's eyes
Solution Approach 1:
The patent replaces liquid crystal display panels with organic light-emitting display panels that have higher light transmissivity. This substitution allows more light to pass through the stacked panels, improving light transmissivity from 5% to 30% or more and enhancing the viewing experience.
3Reliability
If liquid crystal display panels are used with time-division operation, then the device can display images, but the structure becomes complex and easy to give rise to malfunction
Solution Approach 1:
The patent replaces the time-division operation mechanism with simultaneous operation of organic light-emitting display panels. This eliminates the need for synchronization controllers and complex switching circuits, simplifying the device structure and improving reliability by removing potential failure points.
