Roll-Slide Display With Ribbed Support Frame for Wrinkle Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll-slide display devices face issues with wrinkle formation and deformation delays during extension, leading to potential damage and increased manufacturing costs due to the use of multiple components like plate bottoms and rolling belts.
Innovation Solution
A roll-slide display device with an integrated support frame comprising a first, second, and third frame, along with a flexible display unit having ribs and bridges, which alleviates wrinkle formation and reduces manufacturing complexity while maintaining durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (plate bottom and rolling belt) are used to prevent wrinkles, then wrinkle prevention is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the plate bottom and rolling belt into a single integrated support frame structure. The support frame includes a bottom plate with multiple support ribs that simultaneously provide the functions of both the plate bottom (structural support) and the rolling belt (wrinkle prevention during rolling operation), thereby reducing component count while maintaining wrinkle prevention capability
Solution Approach 2:
The support frame is designed as a multi-functional component that performs multiple functions: it provides structural support for the flexible display, prevents wrinkles during rolling and unrolling, and maintains the display in a fixed position. This universal design eliminates the need for separate dedicated components for each function
2Area of moving object
If the flexible display is extended from the body, then screen size is increased, but wrinkle formation occurs due to delayed deformation restoration
Solution Approach 1:
The support frame is pre-configured with support ribs positioned to contact the flexible display before rolling begins. These ribs provide preliminary support to the display surface, preventing deformation and wrinkle formation as the display is extended from the rolled state to the extended state
3Reliability
If a rigid support structure is used to prevent wrinkles, then wrinkle prevention is improved, but flexibility of the display is reduced
Solution Approach 1:
The support frame is segmented into multiple support ribs rather than using a single solid rigid plate. This segmentation provides localized support at critical points where wrinkles form during rolling, while leaving other areas flexible and allowing the display to bend and roll as needed
Solution Approach 2:
The support ribs are strategically positioned at locations where the flexible display is most susceptible to wrinkle formation during rolling. This localized support provides wrinkle prevention exactly where needed while maintaining flexibility in other areas of the display

AI summary
A roll-slide display device may include a first frame, a second frame, a third frame, the first frame, the second frame and the third frame constituting an exterior of the roll-slide display device, and a flexible display unit. The flexible display unit may include a first area fixed directly to the first frame, a second area coupled to the third frame, a third area positioned between the first area and the second area, a display panel, and a support frame disposed on a rear surface of the display panel. Additionally, the support frame may include a plurality of ribs elongated in one direction, a plurality of bridges that connect the plurality of ribs to each other and are integrated with the plurality of ribs to form one body, and a plurality of holes formed between the plurality of bridges arranged in the one direction.
