Solution Overview
Problem
The conventional process of attaching light-shielding tape to display modules is labor-intensive and lacks alignment accuracy, particularly for narrow-border models, leading to suboptimal yield in the assembly process.
Innovation Solution
An automated display module assembly method using a UV-curable resin glue with specific contact surfaces and optical properties, applied through continuous or segmented coating profiles, to facilitate alignment and bonding between the display panel and backlight module, reducing manual labor and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tape attachment is used, then flexibility in handling is maintained, but alignment accuracy and productivity deteriorate
Solution Approach 1:
The patent replaces manual mechanical tape attachment with an automated dispensing system that applies adhesive directly to the display panel edges. This automation eliminates human eye alignment limitations while maintaining flexible positioning through programmable control, simultaneously improving both alignment accuracy and assembly speed.
Solution Approach 2:
The patent introduces an adhesive as an intermediary substance between the display panel and the supporting structure, replacing the traditional light-shielding tape. This adhesive layer provides both bonding function and positioning capability, allowing automated application with high precision while eliminating the need for manual tape alignment.
2Ease of manufacture
If manual tape attachment is used, then process simplicity is maintained, but labor intensity and time consumption increase
Solution Approach 1:
The patent replaces manual tape attachment operations with an automated adhesive dispensing system controlled by computer programming. This substitution maintains process simplicity through standardized automated operations while dramatically reducing attachment time and labor intensity through continuous automated application.
Solution Approach 2:
The patent applies adhesive to the display panel edges before assembly, allowing precise positioning to be established in advance. This preliminary adhesive application enables subsequent rapid assembly operations, reducing total attachment time while maintaining manufacturing simplicity through standardized procedures.
3Object-affected harmful factors
If light-shielding tape is used for narrow-border models, then light-shielding function is achieved, but alignment difficulty increases
Solution Approach 1:
The patent uses adhesive as an intermediary material that serves both bonding and positioning functions, replacing light-shielding tape in narrow-border applications. This approach maintains the necessary light-shielding effect through proper adhesive selection while eliminating alignment difficulties through automated dispensing with precise positioning control.
