Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display devices, particularly 3D TVs, face issues with non-uniform display characteristics and the Moire phenomenon due to temperature deviations and the position of light sources, leading to uncomfortable viewing experiences and image distortion.
Innovation Solution
A display device with a conductive pattern featuring an irregular pattern, comprising a combination of conductive heating and non-heating patterns, is used to maintain uniform display characteristics across temperature changes and light source positions, minimizing the Moire phenomenon by distributing heat uniformly and preventing visual field interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a regular conductive pattern is used for heating, then the manufacturing precision is improved, but the Moire phenomenon occurs causing display quality deterioration
Solution Approach 1:
The patent applies asymmetry by using an irregular conductive pattern instead of a regular geometric pattern. The conductive pattern is designed with random or pseudo-random distribution of conductive lines, eliminating the periodic structure that causes Moire interference with the liquid crystal pixel pattern while maintaining effective heat distribution across the display panel.
2Device complexity
If the light source is positioned at the edge of the display, then the device structure is simplified, but temperature deviation occurs causing non-uniform display characteristics
Solution Approach 1:
The patent applies local quality by positioning the light source at the edge of the display where it can most effectively heat the liquid crystal layer in that region. The irregular conductive pattern is strategically designed to distribute electrical current and generate Joule heating in specific areas, particularly compensating for temperature deviations caused by the edge-mounted light source, thereby achieving uniform temperature distribution across the entire display panel.
3Speed
If the liquid crystal switching speed increases at high temperature, then the 3D display performance is improved, but temperature control becomes critical to prevent image distortion
Solution Approach 1:
The patent implements a feedback mechanism where the irregular conductive pattern acts as a heating element that responds to temperature variations. The non-uniform current distribution in the irregular pattern creates localized heating zones that compensate for temperature deviations, automatically adjusting the temperature profile to maintain optimal liquid crystal switching performance and prevent image distortion in 3D display modes.
