Angled Tiled Display Panels to Eliminate Joint Dark Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with tiled display panels suffer from dark lines at the tiling joints due to obvious intervals between adjacent panels, affecting display quality.
Innovation Solution
The display device employs a tiling method with display panels angled greater than 0 degrees and less than a predetermined angle relative to the backplane, using supporting members to maintain consistent distances to a front light module, and incorporating a cover plate and connecting material to minimize joint gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display panels are tiled in a general flat manner, then the installation is simple, but there will be an obvious interval between adjacent panels resulting in dark lines at the tiling joint
Solution Approach 1:
The patent applies asymmetry by tilting adjacent display panels in opposite directions (e.g., left panel tilts left, right panel tilts right) relative to the backplane. This asymmetric tilting arrangement causes the panels to overlap at the joints, eliminating the dark lines that would otherwise appear from flat tiling. The asymmetric orientation is specifically designed to make the panel edges align at the joints while maintaining ease of installation through a standardized tilting mechanism.
2Object-affected harmful factors
If display panels are tilted to eliminate dark lines, then the display quality improves, but the structural complexity increases
Solution Approach 1:
The patent introduces an intermediary component (the tilting mechanism or adjusting device) that mediates between the backplane and the display panels. This intermediary allows the panels to be tilted to the optimal angle for eliminating dark lines while simplifying the overall structure by providing a standardized interface for adjustment. The intermediary component handles the complexity of angular positioning, allowing the main display structure to remain relatively simple.
3Object-affected harmful factors
If display panels are angled to maintain uniform distances to front light module, then the visual effect is uniform, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by establishing an optimal angular range (greater than 0 degree and less than a predetermined angle) for tilting the display panels. By defining this specific parameter range, the system achieves uniform visual effects without requiring extremely precise manufacturing. The parameter change approach allows for tolerance in actual panel angles while still maintaining the desired visual uniformity, thereby reducing the stringency of manufacturing precision requirements.

AI summary
A display device includes a tiling unit, a front light module disposed on the tiling unit, and a cover plate disposed on the front light module. The tiling unit includes a backplane and display panels. The display panels are disposed on the backplane in a first direction and have an angle greater than 0 degree and less than a predetermined angle with the backplane apiece. Each display panel has a terminal connection side and a counter side opposite to the terminal connection side. Among two adjacent display panels, the counter side of one of the two adjacent display panels is arranged corresponding to the terminal connection side of the other one of the two adjacent display panels, and the one of the two adjacent display panels covers the terminal connection side of the other one of the two adjacent display panels.
