Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stretchable flexible display panels experience a reduction in pixel density when stretched, leading to lower display brightness and image quality due to enlarged spacing between pixel islands.
Innovation Solution
A flexible display panel design featuring an elastic substrate with main and auxiliary pixel islands, where the main pixel islands enclose the auxiliary pixel islands in the natural state and expose them in the stretched state, maintaining pixel density and improving display performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixel islands are arranged with stretched portions between them to enable flexibility, then the display panel can be stretched, but the pixel density of the stretched portion is reduced
Solution Approach 1:
The display panel is segmented into main pixel islands and auxiliary pixel islands, with the auxiliary pixel islands specifically positioned to be exposed during stretching. This segmentation allows different regions to serve different functions: main pixel islands for normal display and auxiliary pixel islands for maintaining pixel density during stretching.
Solution Approach 2:
The arrangement of pixel islands is designed to be dynamic relative to the stretching state. In the natural state, auxiliary pixel islands are enclosed and not visible. When stretched, the auxiliary pixel islands are exposed and become functional. This dynamic configuration allows the display panel to maintain appropriate pixel density in both stretched and non-stretched states.
2Adaptability or versatility
If spacing between pixel islands is enlarged to accommodate stretching, then the display panel can be stretched, but display brightness and image quality deteriorate
Solution Approach 1:
The auxiliary pixel islands are pre-positioned between the main pixel islands in the natural state, enclosed within the space formed by adjacent main pixel islands. This preliminary arrangement ensures that when stretching occurs, the auxiliary pixel islands are already in position to be exposed and contribute to maintaining display brightness and image quality.
Solution Approach 2:
The solution adds a spatial dimension consideration by positioning auxiliary pixel islands in the gaps between main pixel islands. This utilizes the available space in another dimension (the inter-pixel-space) to provide additional functional elements that activate during stretching, thereby maintaining illumination intensity without compromising stretchability.
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 design maintains pixel density in the natural state and increases it in the stretched state, enhancing image display quality by ensuring the auxiliary pixel islands cooperate with main pixel islands to fill in non-luminous areas between adjacent main pixel islands.
Implementation Method 1
an elastic substrate; when the elastic substrate is in a natural state, the main pixel islands adjacent to the auxiliary pixel islands are close to the auxiliary pixel islands... and when the elastic substrate is in a stretched state, the main pixel islands adjacent to the auxiliary pixel islands are away from the auxiliary pixel islands

AI summary
The present application provides a flexible display panel, a manufacturing method of the flexible display panel, and an electronic device. The flexible display panel includes an elastic substrate, main pixel islands, and auxiliary pixel islands. When the elastic substrate is in a natural state, the main pixel islands enclose a light emitting side of the auxiliary pixel islands to receive the auxiliary pixel islands. When the elastic substrate is in a stretched state, the main pixel islands are away from the auxiliary pixel islands to expose the auxiliary pixel islands, and the auxiliary pixel islands cooperate with the main pixel islands for displaying images. Accordingly, the present application increases a pixel density of a stretched portion of the flexible display panel.
