Display Module Protective Tape Filler for IC Height Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display modules are prone to electrostatic breakdown, scratching, and moisture intrusion due to the height differences of the driving integrated circuit (IC), which affects the quality of the display screen.
Innovation Solution
A display module with a protective tape that includes a second adhesive material, which is formed by heating a first adhesive material to fill the area between the adhesive tape and the display panel, providing complete coverage and protection to the driving IC, using an optical clear adhesive and an inorganic adhesive tape to prevent water and oxygen erosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective tape is disposed on the driving IC to prevent electrostatic breakdown, scratching, or moisture intrusion, then the driving IC is protected from damage, but the height differences of the driving IC on the bonding area prevent the protective tape from closely adhering to the driving IC, allowing moisture to enter
Solution Approach 1:
The patent applies preliminary action by pre-forming a filler structure on the bonding area before attaching the protective tape. This filler structure compensates for height differences in advance, ensuring that the protective tape can be flatly attached without gaps, thereby preventing moisture intrusion while maintaining reliable protection of the driving IC.
2Device complexity
If the protective tape is attached directly to the driving IC without filling height differences, then the structure is simple, but moisture in the air easily enters the driving IC, affecting the quality of the display screen
Solution Approach 1:
The patent introduces an intermediary filler structure between the bonding area and the protective tape. This filler structure acts as a mediator that eliminates height differences and prevents gaps, thereby blocking moisture intrusion paths while maintaining structural simplicity. The filler material serves as a bridge that connects the bonding area to the protective tape surface.

Function Achieved in This Case
The solution effectively prevents the driving IC from being eroded by external water and oxygen, thereby improving the quality and durability of the display screen.
Implementation Method 1
the first adhesive material is placed in a high temperature furnace and expands to fill the area between the adhesive tape and the display panel though a heating process to form the second adhesive material
