Flexible OLED Spliced Screen Transparent Spacing Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spliced screens composed of LED display panels exhibit obvious seams due to the rigid nature of LED panels, leading to suboptimal display effects, whereas OLED panels, being flexible, eliminate seams but still face display defects from spacing regions.
Innovation Solution
A spliced screen design incorporating flexible OLED panels with overlapping second display regions and transparent spacing regions, where the second display panels' light outgoing directions match those of the first panels, allowing emitted light to pass through the transparent spacing regions and enhance the display effect by eliminating seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED display panels are used in spliced screens, then the screen structure is stable and easy to manufacture, but obvious seams appear due to the rigid nature of LED panels
Solution Approach 1:
The patent employs flexible OLED display panels instead of rigid LED panels. The flexible nature of OLED panels allows them to conform and splice together without visible seams, eliminating the segmentation effect while maintaining manufacturing feasibility through modular assembly of flexible units.
2Shape
If flexible OLED panels are used to eliminate seams, then the display effect is improved, but spacing regions cause display defects
Solution Approach 1:
The patent extracts the spacing region from the display area by positioning the second display panel's display region to overlap with the spacing region of the first display panel. This ensures that the spacing region, which would otherwise cause display defects, is covered by the overlapping display region, eliminating the defect while preserving the seamless appearance.
Solution Approach 2:
The patent resolves the spacing region issue by utilizing the thickness dimension. The second display panel is positioned such that its display region extends into the thickness direction to overlap with the spacing region, effectively covering the potential defect area in three-dimensional space.
3Manufacturing precision
If the second display panel is positioned to overlap the spacing region, then display defects are compensated, but the structural complexity increases
Solution Approach 1:
The patent merges the spacing region with the display region of the second panel by positioning them to overlap. This integration ensures that the spacing region serves dual purposes: maintaining the flexible structure while also functioning as part of the display area, thereby compensating for potential display defects without significantly increasing structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves the display effect by compensating for display defects caused by seams, providing a seamless and enhanced visual experience by ensuring that the spacing regions are transparent and part of the light-emitting area, thus improving the overall display quality of spliced screens.
Implementation Method 1
the first non-display region is a light-transmitting region... the spacing region includes at least part of the first non-display regions of the two adjacent first display panels... allowing emitted light to pass through the transparent spacing regions

AI summary
A spliced screen and a display apparatus are provided. The spliced screen includes: first display panels spliced together, each of which includes a first display region and a first non-display region around the first display region; the first non-display region is a light-transmitting region; and second display panels on non-display sides of the first display panels, each of the second display panels includes a second display region and a second non-display region around the second display region, and light outgoing directions of first and second display panels are the same. A spacing region is arranged between the first display regions of any two adjacent first display panels, and the spacing region includes at least part of the first non-display regions of the two adjacent first display panels; the second display region and the spacing region overlap each other in a thickness direction of the spliced screen.
