Liquid Crystal Panel Recycling via Discard Region Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for withdrawing liquid crystals from panels are inefficient due to the narrow slots used, making it difficult to separate and recycle the liquid crystal and housing effectively.
Innovation Solution
A method involving the formation of through holes in the discard region of a liquid crystal panel, liquefying the liquid crystal, and using pressure differences to withdraw it through these holes, followed by cutting and sealing to facilitate recycling and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a narrow slot is used to withdraw liquid crystal from the liquid crystal panel, then the structural integrity of the panel is maintained, but the withdrawing efficiency is reduced
Solution Approach 1:
The invention divides the panel into a discard region and a reserve region, and forms multiple through holes in the discard region substrate. This segmentation allows liquid crystal to be withdrawn through multiple distributed holes rather than a single narrow slot, significantly improving withdrawing efficiency while maintaining panel structure
Solution Approach 2:
The invention extracts the liquid crystal withdrawal function from the narrow slot configuration and relocates it to multiple through holes formed in the discard region substrate. This extraction enables more efficient liquid crystal removal while preserving the reserve region for potential reuse
2Reliability
If the whole liquid crystal panel is replaced when the housing breaks or liquid crystal is defective, then the reliability is maintained, but the loss of substance increases
Solution Approach 1:
The invention extracts the liquid crystal from the damaged panel through through holes in the discard region, separating it from the housing. This allows the liquid crystal to be recovered and reused while only the damaged housing is replaced, significantly reducing substance loss
Solution Approach 2:
The invention implements a discard and recover strategy by directing withdrawn liquid crystal to a collection container. The liquid crystal is discarded from the damaged panel but recovered for potential reuse in other panels, reducing waste while maintaining reliability standards
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for efficient withdrawal and recycling of liquid crystals, enabling the reuse of both the liquid crystal and the housing, thereby reducing waste and conserving resources.
Implementation Method 1

AI summary
A method for withdrawing a liquid crystal from a liquid crystal panel includes the steps of: (a) providing a liquid crystal panel that includes a liquid crystal and two spaced-apart substrates cooperatively defining an accommodating space therebetween to accommodate the liquid crystal, and that is divided into a discard region and a reserve region; (b) forming a through hole that is located in the discard region in one of the substrates; and (c) liquefying the liquid crystal that is accommodated in the accommodating space, followed by withdrawing the liquid crystal from the accommodating space through the through hole. A method for recycling a liquid crystal panel is also disclosed.
