Stretchable Display Panel with Staggered Sub-Pixels for Higher Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stretchable display panels suffer from low resolution when stretched, resulting in poor display quality.
Innovation Solution
A display panel design with different stretching amounts for buffer layers on opposite substrates, causing encapsulation structures to move different distances and stagger sub-pixels, increasing the number of visible sub-pixels upon stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display panel is stretched to expand display area, then the display area increases, but the resolution decreases
Solution Approach 1:
The display panel is divided into two separate substrates (first substrate and second substrate) with各自的 encapsulation structures containing sub-pixels. When stretched, these segmented substrates can move independently, allowing the second substrate to shift and expose additional second-type sub-pixels, thereby maintaining high resolution while expanding display area.
Solution Approach 2:
The invention introduces relative movement between two substrates in the stretching direction, transforming the display expansion from a single-plane area increase to a multi-dimensional configuration where sub-pixels are exposed sequentially. This dimensional approach allows more sub-pixels to be utilized without compromising resolution.
2Device complexity
If buffer layers on both substrates have the same stretching amount, then the structure is simple, but sub-pixels overlap and resolution remains low
Solution Approach 1:
The first buffer layer and second buffer layer are designed with different stretching amounts, creating an asymmetric configuration. This asymmetry causes the first encapsulation structures and second encapsulation structures to move at different rates, resulting in staggered sub-pixel arrangement that increases visible sub-pixel count and improves resolution.
Solution Approach 2:
Different regions of the buffer layers are designed with different stretching characteristics. The first buffer layer and second buffer layer have different stretching amounts in the same direction, creating local quality differences that enable selective exposure of sub-pixels and improve overall display resolution.
