Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized display panels formed by splicing small-sized units suffer from gaps at the splicing positions due to adapter plates, leading to display dark fringes and affecting the display quality.
Innovation Solution
The implementation of connection electrodes on a cover to electrically connect pins of adjacent display units, eliminating the need for adapter plates and reducing splicing gaps, thereby improving display uniformity and eliminating dark fringes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adapter plates are provided at the splicing position of display units for connection, then communication between display units is realized, but relatively large gaps are formed at the splicing position, forming display dark fringes and affecting display quality
Solution Approach 1:
The patent extracts and eliminates the adapter plate component from the splicing structure. By removing the adapter plate that causes gaps, the invention directly addresses the dark fringe problem while maintaining communication functionality through alternative connection methods between display units
Solution Approach 2:
The invention merges the connection function previously performed by separate adapter plates into the display unit structure itself. The splicing connection is integrated directly into the display unit edges, eliminating the need for intermediate adapter components and reducing splicing gaps
2Reliability
If adapter plates are used to connect spliced display units, then electrical connection is achieved, but the splicing gap increases and mechanical stability is compromised
Solution Approach 1:
The invention combines electrical connection and mechanical support functions into the integrated splicing structure of the display units themselves. The connection structure is merged with the display unit body, eliminating separate adapter plates and improving both electrical connection reliability and mechanical stability simultaneously
3Area of stationary object
If multiple small-sized display units are spliced together to form large-sized display panels, then large display area is achieved, but gaps at splicing positions affect display uniformity
Solution Approach 1:
The invention removes the adapter plate component that creates visible gaps at splicing positions. By extracting this problematic element, the display uniformity across the entire large display panel is improved while maintaining the modular advantage of multiple spliced units
Solution Approach 2:
The invention applies specialized connection structures at the local splicing positions of display units. These localized connection designs minimize gaps and ensure uniform display quality across the entire panel, addressing the uniformity issue at critical splicing locations without affecting the overall large display area
