Composite Tape Bonding for Display Panel Binding Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have complex structures and high manufacturing costs due to the use of multiple independent tapes for bonding structural parts in the display panel, which complicates the manufacturing process and increases costs.
Innovation Solution
A display device design that incorporates a composite tape with different film structures, where one piece of composite tape is sufficient to cover and protect the second surface of the display panel, bond the binding part with the corresponding region of the display part, and simplify the structure and manufacturing process, reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple mutually independent tapes are used to bond structural parts in the display panel, then the bonding function is achieved, but the structure and manufacturing process become complicated and manufacturing cost increases
Solution Approach 1:
The patent combines multiple independent tapes (protective tape and bonding tape) into a single composite tape that integrates both functions. The composite tape includes a protective film structure and a bonding film structure in one piece, eliminating the need for separate tapes and simplifying the overall structure and manufacturing process
Solution Approach 2:
The composite tape is designed to perform multiple functions simultaneously: it protects the second surface of the display panel and bonds the binding part to the display panel. This multi-functional design replaces what previously required separate specialized tapes, reducing structural complexity
2Ease of manufacture
If multiple mutually independent tapes are used to bond structural parts in the display panel, then the bonding function is achieved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple independent tapes into a single composite tape structure. By integrating the protective function and bonding function into one composite tape, the quantity of separate tape components is reduced, directly lowering material costs and manufacturing expenses
Solution Approach 2:
The composite tape serves multiple purposes (protection and bonding) that previously required separate tapes. This multi-functionality reduces the total number of components needed, thereby reducing manufacturing cost

AI summary
A display device includes a display panel and a composite tape. The display panel includes a display part, a bendable part and a binding part. The display part includes a first surface and a second surface opposite to the first surface. The second surface includes a first region and a second region, and a vertical projection of the binding part on the second surface is located in the first region. The composite tape includes a first film structure and a second film structure, the first film structure is bonded with the second surface, the second film structure includes at least a first part, a vertical projection of the first part on the second surface is located in the first region, and the first part is bonded with the first film structure and the binding part.
