Rollable Display Support Unit for Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels in rollable displays often suffer from permanent deformation when stored for a long time, making it difficult to return to a flat state upon unrolling due to continuous stress.
Innovation Solution
A display device design featuring a flexible display panel, a jig for rolling, a handle for unrolling, and a support unit with a frame guide and support frame that includes track grooves and engaging portions to maintain the panel flat when unrolled, using a combination of rotational and sliding connections to manage stress and facilitate unrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display panel is rolled up into the housing for portability, then the device becomes compact and portable, but the display panel undergoes continuous stress and becomes permanently deformed
Solution Approach 1:
A support unit is introduced as an intermediary component between the flexible display panel and the housing. This support unit includes a support frame with track grooves and engaging portions that temporarily maintain the display panel in a flat state during storage, preventing permanent deformation while allowing the device to remain compact when rolled up.
2Duration of action of stationary object
If the flexible display panel is stored rolled up for a long time, then the device remains compact, but the display panel becomes difficult to return to a flat state
Solution Approach 1:
The support unit is designed to be engaged with the flexible display panel before long-term storage occurs. By preliminarily establishing the flat state configuration through the support frame and engaging portions, the system prevents stress accumulation that would otherwise make unrolling difficult after extended storage periods.
3Stability of the object's composition
If the support unit is added to maintain display flatness, then the display panel remains substantially flat when unrolled, but the device complexity increases
Solution Approach 1:
The support unit is segmented into distinct functional components: a support frame with track grooves, engaging portions that interface with the display panel, and connection mechanisms to the housing. This segmentation allows each component to perform its specific function while keeping the overall structure manageable and facilitating easier assembly and manufacturing.
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 solution effectively maintains the flexible display panel in a substantially flat state when unrolled, preventing deformation and ensuring reliable operation.
Implementation Method 1
a support frame having one end rotatably coupled to the handle or the housing and the other end slidably coupled to the track groove of the frame guide to move therealong

AI summary
A rollable display is disclosed. In one aspect, the display includes a flexible display panel having first and second opposing ends and a jig connected to the first end of the flexible display panel. The flexible display panel is configured to be rolled around the jig. The display also includes a handle connected to the second end of the flexible display panel, a housing configured to accommodate the flexible display panel when rolled around the jig and a support unit connecting the handle to the housing. The support unit includes a frame guide having a track groove defined in a surface of the frame guide and a support frame. The support frame has a first end rotatably connected to one of the handle or the housing and a second end slidably connected to the track groove of the frame guide.
