Display Panel IC Protection via Thick Supporting Component Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual cutting process of display panels generates glass debris, which often scratches the integrated circuit (IC), leading to high defective rates due to the lack of effective detection methods.
Innovation Solution
A display panel design featuring supporting components with a thickness greater than the IC, made of glass cement, is arranged around the IC to create a buffer zone, reducing the likelihood of scratches during manual removal of the cover glass, and a sealant is coated at the display region to enhance protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to remove cover glass and cut panels, then flexibility and adaptability are improved, but glass debris is generated that scratches the IC
Solution Approach 1:
The patent applies beforehand cushioning by placing a buffer layer between the IC and the cover glass before manual removal operations. This buffer layer absorbs the impact and prevents glass debris from directly contacting and scratching the IC, thus resolving the contradiction between manual operation flexibility and IC protection.
Solution Approach 2:
The patent introduces an intermediary buffer layer that mediates between the manual cutting operation and the IC. This intermediary structure absorbs the harmful effects of glass debris generation during manual operations while maintaining the flexibility of manual processing, thus protecting the IC without eliminating operational adaptability.
2Difficulty of detecting and measuring
If manual detection of IC scratches is used, then detection capability is improved, but detection accuracy deteriorates due to human error
Solution Approach 1:
The patent applies self-service by designing the buffer layer to automatically protect the IC during manual operations. The buffer layer itself performs the protective function without requiring external detection or intervention, preventing scratches before they occur and eliminating the need for subsequent manual detection, thus improving both detection capability and accuracy.
3Object-affected harmful factors
If supporting components with greater thickness than IC are added, then IC protection is improved, but device complexity increases
Solution Approach 1:
The patent employs flexible shells and thin films by using a thin buffer layer that is sufficient to protect the IC from glass debris. This thin film approach provides adequate protection without adding significant structural complexity, thus resolving the contradiction between IC protection and device simplicity.
Solution Approach 2:
The patent applies parameter changes by optimizing the thickness of the buffer layer to be greater than the IC thickness, which is the minimum required for protection. This precise parameter control ensures adequate protection while minimizing the addition of structural complexity, balancing protection needs with device simplicity.

AI summary
A display panel and a method for forming the same are disclosed. The display panel includes a first substrate and a second substrate arranged opposite to each other. An integrated circuit (IC) is arranged at a non-display region of the first substrate, and at least one supporting component is arranged beyond a portion of the non-display region where the IC is arranged. A thickness of the at least one supporting component is larger than a thickness of the IC.
