Folded Double-Side OLED Display Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-side OLED displays have complex production processes and thick products due to the adherence of two separate panels, which complicates manufacturing and increases product thickness.
Innovation Solution
A double-side OLED display design where a base layer and OLED layer are folded such that the first and second display regions face opposite directions, eliminating the need for panel separation and adherence, with the base layer located outside to protect the OLED layer and provide a flat display surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display panels are adhered together to form a double-side display, then double-side display function is achieved, but the production process becomes complicated and product thickness increases
Solution Approach 1:
The OLED layer is divided into two separate display regions (first display region and second display region) that are disposed on opposite sides of the base layer, allowing each region to function independently while maintaining a unified structure that simplifies manufacturing
Solution Approach 2:
The display structure transitions from a planar two-panel assembly to a three-dimensional configuration where the OLED layer is folded or bent such that the two display regions face opposite directions, achieving double-side display without requiring two separate panels to be adhered together
2Adaptability or versatility
If two display panels are adhered together to form a double-side display, then double-side display function is achieved, but product thickness increases
Solution Approach 1:
One display region is positioned within or alongside the other display region in the folded structure, with both regions sharing the same base layer and OLED layer materials, thereby reducing overall thickness compared to two separate adhered panels
Solution Approach 2:
The OLED layer is folded or bent to create a three-dimensional structure where display regions face opposite directions, achieving double-side display functionality while maintaining a compact, thin profile by utilizing spatial arrangement rather than stacking two full panels

AI summary
A double-side OLED display is disclosed. The double-side OLED display includes a base layer and an OLED layer disposed on the base layer. The OLED layer includes a first display region and a second display region. The base layer and the OLED layer are folded such that the first display region and the second display region respectively face toward opposite directions; the base layer is located at an outside. The present invention can simplify the production process, increase the production capacity, decrease the thickness of the product, and sufficiently utilizing the base layer such that the base layer can protect the OLED layer. Besides, because the displaying at both sides is emitting at a bottom, the base layer located at outside can provide a flat display surface to improve the display quality.
