Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of electronic display products is limited by the large space occupied by bonding regions, which affects the visual effect of spliced screens and the implementation of narrow frames, particularly due to excessive gaps between adjacent screens.
Innovation Solution
A substrate with a base having a display region and a non-display region, where the non-display region includes a bonding region arranged on the end-side, featuring a joining part with a flexible circuit board and a conductive adhesive layer, allowing for electrical connection with signal lines, thereby reducing the width of the non-display region and facilitating a narrow frame design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the bonding region is arranged in the conventional position, then the bonding function is ensured, but the non-display region width increases, affecting narrow frame design
Solution Approach 1:
The bonding region is repositioned from a conventional lateral arrangement to an end-side arrangement of the base, utilizing the vertical/different spatial dimension. This dimensional repositioning allows the bonding function to be maintained while significantly reducing the width of the non-display region, enabling narrow frame design.
2Area of stationary object
If the bonding region occupies large space, then the bonding structure is stable, but the visual effect of spliced screens deteriorates due to excessive gaps
Solution Approach 1:
The bonding region is extracted from the conventional lateral position and repositioned to the end-side of the base. This extraction and relocation reduces the bonding region's occupation of lateral space, thereby minimizing gaps between adjacent screens in spliced screen configurations while maintaining bonding stability through the end-side positioning.
3Reliability
If the bonding region is positioned conventionally, then the electrical connection is reliable, but the frame width increases
Solution Approach 1:
The electrical connection structure is repositioned to the end-side of the base, utilizing a different spatial arrangement. This dimensional change allows the electrical connection to remain reliable while reducing the lateral extent of the frame, achieving narrow frame width without compromising connection reliability.
