Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current splicing display screens face issues with large gaps and height differences between adjacent panels due to assembly and machining tolerances, leading to reduced display quality.
Innovation Solution
A splicing display screen design featuring a backplate with sub-display panels aligned to form a seamless plane, using an adhesive layer with dispensing process-formed sub-adhesive portions to connect panels, and optionally including a reinforcement layer and second adhesive layer for enhanced stability and adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If positioning holes and posts are used to assemble display panels, then assembly is simplified, but large gaps and height differences occur between adjacent panels
Solution Approach 1:
A positioning clamp is introduced as an intermediary component between the positioning holes and the display panels. The clamp spans across multiple panels and uses a clamping mechanism to apply uniform pressure, forcing the panels into precise alignment while accounting for manufacturing tolerances in the positioning holes themselves
Solution Approach 2:
The assembly system transitions from a static rigid connection (direct hole-to-post fitting) to a dynamic adjustable system. The positioning clamp allows for real-time adjustment and application of clamping force during assembly, enabling compensation for dimensional variations and achieving precise panel alignment despite tolerance accumulations
2Area of stationary object
If multiple display panels are spliced together to increase size, then display area is expanded, but gaps between panels increase
Solution Approach 1:
The positioning clamp is designed as a segmented structure that can independently adjust and clamp each panel interface. Multiple clamping points along the clamp's length allow for localized precision control at each panel junction, ensuring uniform gap control across the entire spliced display assembly
Solution Approach 2:
The positioning clamp acts as a mediator that physically bridges and aligns multiple display panels during assembly. By providing a common reference plane and applying distributed clamping forces, it ensures that panels are positioned with consistent spacing and minimal gaps across the entire display area
3Ease of manufacture
If positioning holes with tolerances are used, then manufacturing is easier, but height differences between panels occur
Solution Approach 1:
The positioning clamp introduces a dynamic adjustment mechanism that compensates for the static dimensional variations in positioning holes. By allowing for clamping force application and positional adjustment during assembly, the system can achieve a flat, uniform panel surface despite variations in hole dimensions and panel thicknesses
Solution Approach 2:
The positioning clamp is designed to be applied before final panel installation, allowing for preliminary alignment and height equalization. The clamping action pre-adjusts panel positions and eliminates height differences before the panels are permanently fixed, ensuring a flat overall surface

AI summary
The present application provides a splicing display screen and a manufacturing method thereof. The splicing display screen includes a backplate. In the present application, a plurality of sub-display panels disposed on the backplate, an adhesive layer disposed between the backplate and the sub-display panels, and a plurality of first sub-surfaces configured to display images in the sub-display panels are arranged on a same plane. The adhesive layer at least corresponds to a gap between every two adjacent sub-display panels to connect every two adjacent sub-display panels.
