Display Panel Bridge Region Pixel Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stretchable display apparatuses face issues with reduced effective display area due to dark regions and screen door effects, leading to discontinuous lines and poor image presentation when trying to expand their screen size.
Innovation Solution
A display panel design featuring a base with island regions and bridge regions, where second pixels are strategically placed in bridge regions to increase the light-emitting area, reducing dark regions and improving image continuity and detail.

Engineering Contradiction Analysis
1Area of stationary object
If the screen area is expanded by pulling out hidden screen, then the overall effective display area is increased, but dark regions and screen door effects appear reducing the quality of display
Solution Approach 1:
The base is segmented into multiple island regions and bridge regions, allowing pixels to be distributed across both types of regions. This segmentation enables the display to maintain continuity while expanding the effective display area, reducing dark regions and screen door effects by ensuring pixel coverage in previously unused bridge areas.
Solution Approach 2:
The invention transitions from a single continuous screen structure to a multi-dimensional arrangement with island regions connected by bridge regions. Second pixels are placed in bridge regions to fill gaps between island regions, effectively utilizing space in multiple dimensions to reduce dark regions and improve display continuity when the screen is expanded.
2Area of stationary object
If second pixels are added in bridge regions, then the light-emitting area is increased, but the device complexity increases
Solution Approach 1:
The base structure serves multiple functions: it provides mechanical support, defines pixel arrangement zones (island and bridge regions), and enables both first pixels in island regions and second pixels in bridge regions to function together. This multi-functionality increases light-emitting area without proportionally increasing device complexity, as the same base structure accomplishes multiple objectives.

AI summary
A display panel includes a base, a plurality of first pixels disposed on the base, and at least one second pixel disposed on the base. The base has a plurality of island regions spaced apart and a plurality of bridge regions connecting the plurality of island regions. Each bridge region includes a first region and two second regions disposed on two opposite sides of the first region. Each second region is directly connected to a corresponding one of the plurality of island regions. The base includes a plurality of openings, each opening is disposed between two adjacent bridge regions. Each island region is provided with at least one first pixel therein. The at least one second pixel is disposed in at least one of second regions of the plurality of bridge regions.
