Rollable Display Apparatus Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with rollable displays face increased size due to the need for separate internal space for both the display and protection member, leading to inefficient use of internal space when both are wound for storage.
Innovation Solution
A compact display apparatus design featuring a housing with a first and second roll, where the display is wound on the first roll and the protection member can be wound on either roll, along with a moveable component mounting part that adjusts its position based on the expansion and contraction of the rolls to optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate rolls are provided for display and protection member accommodation, then both components can be stored and protected, but the overall size of the display apparatus increases
Solution Approach 1:
The patent combines the display roll and protection member roll into a single integrated roll structure. The display and protection member are wound together on the same roll, eliminating the need for separate accommodation spaces. This merging approach maintains the protective function while reducing the overall apparatus size.
Solution Approach 2:
The single roll serves multiple functions: it accommodates both the display and the protection member, and provides structural support for both components. The roll acts as a universal accommodation mechanism that replaces what would traditionally require separate dedicated structures for each component.
2Temperature
If the protection member is kept separate from the display during retraction, then heat dissipation is improved, but internal space requirements increase
Solution Approach 1:
The protection member is nested within the display structure during retraction, with both components wound together on the same roll. This nesting arrangement allows the protection member to be positioned adjacent to the display without requiring separate accommodation volume, while still maintaining thermal separation through the layered winding structure.
3Length of stationary object
If the display is wound tightly for compact storage, then apparatus size is reduced, but the display panel may be damaged due to direct contact
Solution Approach 1:
The display and protection member are combined in a single winding structure where the protection member is interlaced with the display. This combined structure ensures that the protection member remains positioned between the top and bottom surfaces of the display during winding, preventing direct contact and damage while enabling tight winding for compact storage.

AI summary
A display apparatus is provided. The display apparatus includes a housing having an opening, a first roll and a second roll rotatably provided within the housing, a display configured to be wound on the first roll, and to be retracted and withdrawn through the opening according to a rotation direction of the first roll, a protection member configured to be wound on the first roll together with the display or to be wound in the second roll as the display is withdrawn from the housing, and a moveable component mounting part which is disposed between the first roll and the second roll and on which various components are mounted within the housing. The component mounting part moves within the housing to selectively provide space and utilize space according to a retraction operation and a withdrawal operation of the display.
