Solution Overview
Problem
Existing spliced display screens suffer from bright lines at splicing gaps due to high brightness, affecting image display performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If adjacent display panels are spliced together to form large-size screens, then portability and low power consumption are improved, but splicing gaps appear causing high brightness and affecting image display performance
Solution Approach 1:
A light transmission covering layer is introduced as an intermediary component between adjacent display panels. This layer extends beyond the substrate edge and covers the splicing gap, acting as a mediator to block or reduce the light leakage that causes high brightness at splicing gaps, while maintaining the overall spliced display structure's energy efficiency benefits
Solution Approach 2:
The light transmission covering layer is selectively positioned only at the edge regions where splicing gaps occur, rather than covering the entire display panel. This localized approach addresses the specific problem of high brightness at splicing gaps without unnecessarily increasing power consumption across the whole display area
2Area of stationary object
If adjacent display panels are spliced together, then large-size display capability is improved, but splicing gaps cause high brightness that affects image display performance
Solution Approach 1:
The light transmission covering layer serves as an intermediary element that fills or covers the splicing gaps between large display panels. It selectively blocks the harmful light leakage at gap regions while allowing the large-size spliced display structure to maintain its image display capability
Solution Approach 2:
The light transmission covering layer is divided into multiple sections corresponding to different splicing gaps between adjacent panels. Each segment addresses the local high brightness issue at its respective gap, allowing the overall large-size display to function properly while eliminating the harmful effects at specific locations
