Optical Member Integration for Slim LCD Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display (LCD) devices face challenges in minimizing the bezel width and thickness due to the structural components like the support main and case top, which hinder the realization of a narrow bezel and lightweight, thinned design.
Innovation Solution
Integration of a liquid crystal panel with a backlight unit using an optical member that surrounds the side surfaces of the backlight unit, reducing the need for structural components like the support main and case top, and enhancing coupling power between the panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If structural components like support main and case top are used to assemble the display device, then the structural stability is improved, but the bezel area increases and the device thickness increases
Solution Approach 1:
The optical member integrates multiple functions: it serves as both an optical element for light management and a structural component for assembling the liquid crystal panel to the backlight unit. This merging eliminates the need for separate support mains and case tops, thereby reducing bezel area while maintaining structural stability.
Solution Approach 2:
The optical member is designed to perform multiple functions simultaneously: light guiding, structural support, and assembly bonding. This multi-functionality allows the removal of dedicated structural components, reducing overall device complexity and bezel dimensions.
2Stability of the object's composition
If structural components like support main and case top are used to assemble the display device, then the structural stability is improved, but the device thickness increases
Solution Approach 1:
The optical member combines structural support and optical functions into a single component, eliminating the need for separate support mains and case tops that would increase device thickness. This integration enables a thinner overall device profile while maintaining necessary structural stability.
3Stability of the object's composition
If multiple separate components are used for assembly, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The optical member consolidates multiple separate components (support main, case top, and optical elements) into a single integrated component. This reduction in part count simplifies the assembly process and reduces device complexity while maintaining structural integrity through the optical member's inherent bonding and support capabilities.
