Glass Light Guide Integration for Slim LCD Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display (LCD) devices are thick and bulky due to the presence of structures like case tops, guide panels, and cover bottoms, which increase the bezel and manufacturing costs.
Innovation Solution
The integration of a light guide formed as one body with the liquid crystal panel, eliminating the need for separate structures like case tops and guide panels, and using a glass light guide with a reflector and adhesive member to combine the light source and light guide, enhancing slimness and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If separate structures like case top, guide panel, and cover bottom are used to support the liquid crystal panel and backlight unit, then the device structure is stable and functional, but the device thickness and bezel are increased
Solution Approach 1:
The patent merges the light guide plate with the liquid crystal panel into a single integrated structure, eliminating the need for separate case top, guide panel, and cover bottom structures. This integration directly reduces device thickness while maintaining structural stability and support functions through the unified design of the light guide plate that now serves both optical guidance and structural support roles.
2Illumination intensity
If multiple optical sheets and support structures are included in the backlight unit, then light distribution is improved, but manufacturing cost and device weight are increased
Solution Approach 1:
The patent extracts and eliminates unnecessary optical sheets from the backlight unit while maintaining light distribution uniformity through the optimized integrated light guide plate design. By removing redundant optical components, the device achieves comparable or improved light uniformity with fewer materials, thereby reducing manufacturing cost and device weight.
3Reliability
If traditional separate structures are used for light source and light guide, then assembly is straightforward, but thermal deformation from light source is not prevented
Solution Approach 1:
The patent integrates the light source directly with the light guide plate in a unified structure, which improves thermal management by reducing thermal resistance between the light source and heat dissipation pathways. This integration prevents thermal deformation while the design maintains ease of manufacture through simplified assembly steps and reduced component count.
4Strength
If case top and guide panel structures are used to cover and support components, then structural protection is provided, but device slimness is compromised
Solution Approach 1:
The patent merges the protective and support functions into the integrated light guide plate structure, which provides necessary structural protection while maintaining device slimness. The unified design eliminates the need for separate case top and guide panel structures, achieving both structural integrity and reduced thickness through multifunctional integration.
