Azobenzene Green Light Sacrificial Layer for Touch Display Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of touch display panels often results in damage to the display panel due to high temperature and chemical processes, leading to peeling of frame glue, separation of glass layers, and potential crushing of circuits, and the removal of scratch-resistant protective layers can damage the touch module, affecting the touch function.
Innovation Solution
A green light sacrificial layer made of an azobenzene derivative is applied to the touch module, which converts from a solid to a liquid state upon irradiation with green light, allowing for its removal without high temperature or high concentration lye, thereby protecting the panel during manufacturing and enhancing its performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the touch module is manufactured after the display panel is completed using external side process, then the thickness of overall films is reduced, but the frame glue peels off and dissolves due to high temperature and chemical processes
Solution Approach 1:
The patent applies a protective layer to the frame glue before the touch module manufacturing process. This preliminary protective coating shields the frame glue from high temperature and chemical agent damage during subsequent CVD, PVD, and printing processes, preventing peeling and dissolution while allowing the external side process to proceed for thickness reduction
2Ease of manufacture
If the display panel is assembled and then the touch module is manufactured, then the overall structure is formed, but local pressures from equipment cause damage to support structure or crushing of circuits
Solution Approach 1:
The patent introduces a protective layer that acts as a cushioning barrier before the touch module manufacturing process begins. This protective coating absorbs and distributes local pressures from vacuum suction washing and curling equipment, preventing direct transmission of stress to the support structure and circuits, thereby avoiding damage while allowing post-assembly manufacturing
3Ease of manufacture
If high temperature and high concentration lye are used to remove the scratch-resistant protective layer, then the protective layer is removed, but the touch module is damaged and touch function fails
Solution Approach 1:
The patent changes the removal parameters from high temperature and high concentration lye to low temperature and low concentration conditions. The protective layer is designed to be removable under mild conditions that do not damage the underlying touch module, preserving touch function while achieving protective layer removal
4Productivity
If conventional manufacturing processes are used, then the display panel can be manufactured, but the performance is affected due to damage from high temperature and chemical processes
Solution Approach 1:
The patent introduces a protective layer as an intermediary between the manufacturing processes and the display panel components. This intermediary layer withstands high temperature and chemical processes during normal manufacturing, allowing conventional productive processes to continue while protecting the panel performance from damage
