Integrated Front Glass and Liquid Crystal Display Module for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly process of liquid crystal display modules in mobile devices faces alignment issues due to manufacturing tolerance between the liquid crystal display module and the cover glass, which hinders the development of thinner, lighter, and narrower rim designs.
Innovation Solution
The solution involves replacing the cover glass with a front glass structure that is integrated into the liquid crystal display module, matching its dimensions with the middle-frame structure, thereby eliminating the need for adherence and reserved spaces, and enhancing the structural strength and optical properties through vacuum coating and silk printing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cover glass structure is used with the liquid crystal display module, then the display can be protected, but manufacturing tolerance causes alignment issues and requires reserved spaces
Solution Approach 1:
The patent combines the cover glass structure with the liquid crystal display module into a single integrated unit. The front glass of the LCM serves as the cover glass, eliminating the need for a separate cover glass assembly and the associated alignment tolerances. This merging resolves the contradiction by maintaining protection functionality while eliminating alignment issues caused by separate component manufacturing tolerances.
Solution Approach 2:
The front glass structure performs multiple functions: it serves as both the protective cover glass and the front substrate of the liquid crystal display module. This multi-functionality eliminates the need for a separate cover glass component, thereby removing the alignment tolerance problems that would arise from assembling two separate components.
2Reliability
If a separate cover glass structure is used with the liquid crystal display module, then the display can be protected, but the device thickness and weight increase
Solution Approach 1:
By merging the cover glass function with the front glass of the LCM, the patent eliminates the need for additional glass layers and adhesive structures that would increase device thickness. The integrated structure achieves protection without the extra thickness that would result from assembling separate cover glass and LCM components.
3Manufacturing precision
If manufacturing tolerance is accommodated with reserved spaces, then alignment issues are resolved, but the device becomes larger and heavier
Solution Approach 1:
The integration of cover glass and LCM into a single unit eliminates the need for reserved spaces or tolerance compensations that would increase device dimensions and weight. The unified structure is manufactured as one component, removing the need for additional materials and space required for separate component assembly and tolerance accommodation.
