Spliced Display Panel Frame Layout for Seamless Large-Area Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses formed by splicing multiple screens often have noticeable seams that degrade the user experience due to frame fit tolerances and splicing methods.
Innovation Solution
The display panel is constructed by splicing display sub-panels with frames bent away from the display surface, allowing adjacent frames to contact, thereby minimizing visible seams and maintaining pixel density consistency across spliced panels.

Engineering Contradiction Analysis
1Area of stationary object
If multiple display screens are spliced together to form a large display apparatus, then the display area is increased, but obvious splicing seams appear that affect user experience
Solution Approach 1:
The frame is bent from a planar configuration to a three-dimensional configuration, extending away from the display surface. This dimensional change allows the frame to be positioned out of the visual plane, eliminating the splicing seam visibility issue while maintaining the spliced structure for large display area coverage.
Solution Approach 2:
The frame is bent into a curved configuration away from the display surface, creating a non-planar structure. This curvature positions the frame edges in three-dimensional space, allowing adjacent display screens to be spliced without visible seams in the front view, thus resolving the contradiction between large display area and seam visibility.
2Object-affected harmful factors
If frames are bent away from the display surface to reduce seam visibility, then splicing seam visibility is reduced, but frame structure complexity increases
Solution Approach 1:
The frame is designed with a simple curved configuration that bends uniformly away from the display surface. This curved design achieves the goal of reducing seam visibility while maintaining relative structural simplicity, avoiding excessive complexity in the frame structure.
Solution Approach 2:
The bent frame structure serves multiple functions: it provides structural support for the display screen, acts as a mounting interface for splicing adjacent screens, and simultaneously conceals the splicing seams. This multi-functionality reduces the need for additional components, keeping the overall structure relatively simple despite the curvature.
3Object-affected harmful factors
If frames of adjacent display sub-panels are made to contact each other, then splicing seam visibility is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The curved configuration of the frame provides a well-defined geometric interface for contact between adjacent display sub-panels. The curvature creates a consistent contact surface that facilitates alignment, reducing the impact of manufacturing tolerances compared to flat frame edges that would require precise point-to-point alignment.
Solution Approach 2:
By extending the frame into the third dimension (away from the display surface), the contact interface between adjacent panels is created in a different spatial plane. This dimensional separation allows for more tolerant alignment requirements, as the contact can occur along a surface or edge rather than requiring precise edge-to-edge alignment in the same plane.
