Splicing Display Panel Groove Structure for Seam Stability

Solution Overview

Problem

Traditional splicing screens in outdoor displays suffer from visual seam issues due to poor stability, as existing methods of adding light bars to conceal seams result in misalignment and poor stability over time.

Innovation Solution

A splicing display panel design that incorporates a first and second display module with concave parts forming a holding groove for a third display module, ensuring the third module is supported and aligned, thus eliminating suspended areas and improving stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If light bars are disposed at the seam position to eliminate visual seams, then seam visibility is reduced, but the stability of the splicing display panel deteriorates

Engineering Contradiction:

Improveseam eliminationVSAvoidpanel stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The third display module is nested within the concave part formed by the first and second display modules. The concave parts of the first and second display modules surround to form a holding groove that accommodates the third display module, creating a stable nested structure that eliminates the need for separate light bars while maintaining panel stability.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The solution transitions from a two-dimensional arrangement of display modules to a three-dimensional structure by introducing concave parts that extend vertically. The holding groove formed by the concave parts provides vertical support and lateral confinement for the third display module, adding a dimensional aspect that enhances stability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If display modules are spliced together to form large screens, then screen size increases, but visual seams between modules become apparent

Engineering Contradiction:

Solution Approach 1:

The third display module is nested within the concave part formed by the first and second display modules. The concave parts of the first and second display modules surround to form a holding groove that accommodates the third display module, creating a stable nested structure that eliminates the need for separate light bars while maintaining panel stability.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The holding groove structure merges the support function and the seam elimination function into a single integrated design. The concave parts not only provide mechanical support for the third display module but also create a seamless visual appearance by eliminating the need for separate light bar components.

Inventive Principle:

Principle #5Merging (Combining)
