Longitudinal Foldable Display Panel Eliminates Sub-Screen Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of transverse foldable screen systems in flexible OLED displays are increased by the need for a separate sub-screen, which complicates the system and raises manufacturing costs.
Innovation Solution
A longitudinal foldable screen design where a first display part and a second display part are configured along a longitudinal direction, with the second display part foldably connected to the first, allowing for inner and outer surface display regions to combine or separate to form a single image, eliminating the need for a sub-screen and reducing system complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate sub-screen is added to achieve main screen and sub-screen display functions, then display functionality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The single flexible display panel performs multiple functions: it serves as both the main screen and sub-screen through different folding configurations. When unfolded, the entire panel displays the main screen; when folded, it creates a smaller sub-screen display, eliminating the need for separate dedicated sub-screen hardware
Solution Approach 2:
The display system transitions between different operational states through folding and unfolding movements. The flexible display panel dynamically changes its configuration from a flat unfolded state (main screen) to a folded state (sub-screen), allowing one physical component to adapt to multiple display scenarios
2Adaptability or versatility
If a separate sub-screen is added to achieve main screen and sub-screen display functions, then display functionality is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the main screen and sub-screen into a single flexible display panel. By combining both display functions into one integrated component rather than using separate screens, the manufacturing process is simplified and material costs are reduced
3Adaptability or versatility
If transverse foldable screen with separate sub-screen is used, then main screen and sub-screen display is achieved, but system complexity increases
Solution Approach 1:
The patent extracts and eliminates the separate sub-screen component from the transverse foldable design. By removing this redundant element and using only a single flexible display panel that can be configured through folding, the system complexity is significantly reduced while maintaining the dual display functionality

AI summary
A flexible display panel, a display device, and a method for controlling display of the display device are provided. The display device includes the flexible display panel. The flexible display panel is a longitudinal foldable screen. A first display part and a second display part are disposed along a longitudinal direction of the flexible display panel. An upper surface of the first display part is configured to display images. The second display part and the first display part are disposed in one body, and the second display part is foldably connected to a top edge of the first display part.
