Supporting Assistance Member for LCD Through-Hole Sealant Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal displays (LCDs) face challenges in minimizing the area occupied by sealants supporting through-holes, which complicates the manufacturing process and limits size reduction.
Innovation Solution
A supporting assistance member with a through-hole, made of the same material as the spacer, is used to connect and support the substrates, simplifying the manufacturing process and reducing the area occupied by the sealant, by forming the through-hole using an etching layer that connects with the substrate's through-hole.

Engineering Contradiction Analysis
1Area of stationary object
If sealant is used to support through-holes in substrates, then structural integrity is maintained, but the area occupied by sealant increases and manufacturing process becomes complicated
Solution Approach 1:
The supporting assistance member merges the functions of support and through-hole formation into a single integrated component. This member is formed from the same material as the spacer and includes a through-hole that connects the first through-hole in the first substrate with the second through-hole in the second substrate, eliminating the need for separate sealant-based support structures and additional size-reduction processes.
Solution Approach 2:
The supporting assistance member serves multiple functions simultaneously: it provides structural support between substrates, maintains spacing, and creates the through-hole pathway for module insertion. By making it from the same material as the spacer, it integrates seamlessly with existing components while performing these multiple roles, simplifying the overall manufacturing process.
2Area of stationary object
If separate process is added to reduce the size of sealant area, then area occupied by sealant is reduced, but manufacturing process becomes more complicated
Solution Approach 1:
The supporting assistance member is formed in advance during the spacer formation process, before substrate assembly. The through-hole is created as part of this pre-formed component, so no additional size-reduction or hole-formation processes are needed after assembly. This preliminary formation of both the support structure and through-hole pathway eliminates subsequent manufacturing steps.
3Area of stationary object
If through-hole is formed using sealant, then substrate connection is achieved, but area occupied by through-hole increases
Solution Approach 1:
The supporting assistance member provides localized support and through-hole formation precisely where needed, rather than using extensive sealant coverage. The member is positioned to connect specific through-holes in the substrates, creating a focused, minimal-area connection pathway that maintains reliability without occupying excessive area.
