Autoclave Light Source Bubble Removal Adhesive Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices often experience bubble generation after the autoclave process and before the adhesive curing, leading to reduced quality and visibility issues due to air permeation through the edges, which existing methods fail to prevent effectively.
Innovation Solution
An autoclave system with a chamber and cassette configuration that includes light sources for simultaneous bubble removal and adhesive curing under pressurized conditions, ensuring that the curing process occurs within the same environment, preventing bubble generation and reducing overall processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display device is placed in an autoclave to remove bubbles at high temperature and pressure, then bubbles between the display panel and adhesive layer are removed, but bubbles are generated in the display device after the autoclave process and before curing
Solution Approach 1:
The patent combines the bubble removal process and adhesive curing process into a single integrated operation within the autoclave. The adhesive layer is cured while the display device remains under pressurized conditions inside the autoclave, preventing bubble generation that would otherwise occur during the transition between separate processes. This merging eliminates the intermediate state where bubbles can form.
Solution Approach 2:
The patent applies preliminary curing action to the adhesive layer during the autoclave process. By initiating and completing the curing process while the device is still under pressure in the autoclave, the adhesive forms a stable structure before the device is exposed to atmospheric pressure, preventing air permeation and subsequent bubble generation.
2Ease of manufacture
If separate processes are used for bubble removal and adhesive curing, then each process can be optimized independently, but processing time increases and bubbles may generate between processes
Solution Approach 1:
The patent merges the bubble removal autoclave process and the adhesive curing process into a single simultaneous operation. By integrating both functions into one process step, the total processing time is reduced while maintaining the ability to optimize parameters for both functions within the unified process framework.
3Ease of operation
If the adhesive layer is cured after removing the device from the autoclave, then the curing can be performed at standard conditions, but air permeation through edges causes bubble generation
Solution Approach 1:
The patent performs the adhesive curing action preliminarily while the device is still under pressurized conditions in the autoclave. This preliminary curing establishes a sealed adhesive structure before the device is exposed to atmospheric pressure, preventing air from permeating through edges and generating bubbles during or after the curing process.
