Laminated LCD Panel with Gamma Corrector for 2D-3D Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices cannot seamlessly and linearly mix the ratios of high-contrast 2D and 3D displays, hindering smooth medical image diagnosis by forcing users to switch between 2D and 3D modes.
Innovation Solution
A liquid crystal display device comprising two laminated panels with a gamma corrector that performs gamma correction based on external control signals, generating corrected video signals for each panel to produce first and second video signals, allowing seamless and linear adjustment of the mixing ratio between high-contrast 2D and 3D displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If two liquid crystal display panels are disposed to be laminated to achieve high-contrast 2D display, then contrast is improved, but stereoscopic vision is prevented
Solution Approach 1:
The patent applies dynamics by making the display mode switchable between 2D and 3D through temporal multiplexing. The system dynamically alternates between displaying images on the first panel alone (2D mode) and displaying images on both panels (3D mode), allowing the display characteristics to change adaptively based on viewing requirements while maintaining both high contrast and stereoscopic vision capabilities
2Adaptability or versatility
If 2D and 3D display modes are switched to meet different display requirements, then display versatility is improved, but mixing ratio cannot be adjusted seamlessly and linearly
Solution Approach 1:
The patent applies parameter changes by introducing a mixing ratio parameter that can be continuously adjusted between 0 and 1. This parameter controls the degree to which 3D display characteristics are applied to the image data, allowing seamless and linear transition between 2D and 3D display modes. The system changes the display parameters dynamically based on the mixing ratio value, enabling precise control over the balance between contrast enhancement and stereoscopic effect
3Adaptability or versatility
If conventional switching between 2D and 3D modes is used, then display versatility is improved, but smooth diagnosis is obstructed due to inability to view medical images with desired mixing ratio
Solution Approach 1:
The system dynamically adjusts the mixing ratio parameter in real-time based on user input or automatic detection, allowing smooth transition between 2D and 3D display modes without requiring manual switching. This dynamic adjustment enables continuous optimization of display characteristics for different medical imaging scenarios, improving diagnostic smoothness by maintaining the desired display mode throughout the viewing process
