Movable Support for Foldable Display Panel Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable display apparatuses are susceptible to damage in the open state due to lack of support for the foldable display panel, which can lead to mechanical stress and potential breakage during use.
Innovation Solution
A display apparatus design featuring a foldable display panel with bendable and nonbendable flat portions, supported by movable supports within a housing structure that adjusts between unfolded and folded configurations, utilizing tensioning structures to maintain support and protection of the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foldable display panel is designed to be foldable, then the portability and compactness are improved, but the reliability and resistance to mechanical stress deteriorate due to lack of support in the open state
Solution Approach 1:
The support structure is designed to be dynamic, automatically adjusting its configuration based on the display panel's state. When the panel is folded, the support structure provides robust mechanical support; when unfolded, the structure adapts to maintain support while allowing the panel to lie flat, thus resolving the contradiction between foldability and mechanical strength
Solution Approach 2:
A movable support structure acts as an intermediary element between the housing and the foldable display panel. This support structure receives the panel in both folded and unfolded states, providing mechanical protection and support without interfering with the folding function, thereby maintaining reliability while enabling portability
2Reliability
If the display panel is supported in the open state, then the reliability is improved, but the device complexity increases due to additional support structures
Solution Approach 1:
The movable support structure serves multiple functions: it supports the display panel in the folded state for portability, provides mechanical support in the unfolded state to prevent damage, and integrates seamlessly with the housing structure. This multi-functionality reduces the need for separate dedicated support components, thereby limiting the increase in device complexity
Solution Approach 2:
The support structure is designed to be movable rather than fixed, allowing it to adapt its position and configuration based on the panel's state. This dynamic design provides reliable support without requiring complex fixed mechanisms, as the structure simply moves to accommodate the panel in either folded or unfolded position

AI summary
The present application discloses a display apparatus including a foldable display panel comprising a bendable portion, a first nonbendable flat portion and a second nonbendable flat portion on two opposite sides of the bendable portion; a first housing portion and a second housing portion coupled together by a hinge and rotatable with respect to each other between a first configuration corresponding to the foldable display panel in an unfolded configuration and a second configuration corresponding to the foldable display panel in a folded configuration; and a first movable support received in the first housing portion for supporting the first nonbendable flat portion and configured to be movable between a first position corresponding to the unfolded configuration and a second position corresponding to the folded configuration. The first movable support at the first position supporting a part of the bendable portion of the foldable display panel; and the first movable support at the second position providing a space for receiving the bendable portion bent therein.
