Solution Overview
Problem
Current foldable display devices face challenges in encapsulating the edge of the flexible display panel due to changes in the gap between the housing and the bending mechanism, leading to potential exposure and damage from dust and impurities.
Innovation Solution
A foldable display device design featuring a housing with a bending mechanism and a front frame structure that includes rotatable and slidably connected support plates, ensuring the flexible display panel is encapsulated when folded, preventing exposure and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a housing is disposed to slide relative to the bending mechanism to accommodate the flexible screen when folded, then the flexible screen can be accommodated in folded state, but the gap between the housing and the bending mechanism changes making the edge of the flexible screen difficult to be encapsulated
Solution Approach 1:
The patent applies dynamics by making the support plate rotatable relative to the bending mechanism and the housing movable relative to the support plate. This dynamic structure allows the support plate to rotate to different angles during folding, while the housing moves synchronously to maintain a constant gap between the housing and the bending mechanism, ensuring continuous encapsulation of the flexible screen edge throughout the folding process.
Solution Approach 2:
The support plate acts as an intermediary component between the bending mechanism and the housing. It rotates to accommodate the flexible screen in folded state while driving the housing to move synchronously, thereby maintaining the constant gap and ensuring encapsulation. The intermediary structure resolves the conflict between accommodation and encapsulation.
2Adaptability or versatility
If the gap between the housing and the bending mechanism changes during folding, then the flexible screen can be accommodated, but impurities such as dust may enter the flexible screen from the side
Solution Approach 1:
The dynamic structure with the rotatable support plate and synchronously moving housing maintains a constant gap between the housing and the bending mechanism throughout the folding process. This constant gap creates a sealed environment that prevents dust and impurities from entering the flexible screen while still allowing the flexible screen to be accommodated in the folded state.
3Reliability
If the housing is fixed relative to the bending mechanism, then the gap remains constant for encapsulation, but the flexible screen cannot be accommodated when folded
Solution Approach 1:
The patent resolves this contradiction by creating a dynamic system where the support plate rotates and the housing moves synchronously. This dynamic adjustment allows the system to maintain a constant gap for encapsulation while simultaneously accommodating the flexible screen in the folded state. The housing is not fixed but moves in coordination with the rotating support plate.
Solution Approach 2:
The support plate rotates in advance to the appropriate angle before the housing completes its movement, preparing the path for the flexible screen to be accommodated. This preliminary rotation of the support plate enables the subsequent synchronous movement of the housing to maintain encapsulation while accommodating the folded screen.
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 effectively encapsulates the flexible display panel at any angle, preventing exposure and damage by maintaining a consistent gap between the housing and the bending mechanism, thus enhancing protection against dust and impurities.
Implementation Method 1
the first support plate is rotatably connected to the side of the bending portion, an end of the first movement mechanism is slidably connected to the first support plate
Implementation Method 2
an end of the first movement mechanism is slidably connected to the first support plate, and another end of the first movement mechanism is fixedly connected to the first housing
Implementation Method 3
a front frame structure disposed on a side of the flexible display panel away from the housing, covering at least a part of a side surface of the flexible display panel

AI summary
A foldable display device includes a housing, a bending mechanism disposed in the housing, a flexible display panel disposed in the housing and on a side of the bending mechanism, and a front frame structure covering at least a part of a side surface of the flexible display panel. When the foldable display device is folded at any angle, an edge of the flexible display panel and the bending mechanism are encapsulated.
