Flexible Display Panel with Elastic Connection for Size Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display apparatuses face limitations in achieving thinness, weight-lightness, and portability due to the use of glass substrates, which restrict their ability to be easily enlarged or reduced without separate driving power.
Innovation Solution
A display apparatus featuring a display panel movably coupled to a body via elastic connection parts, allowing the panel to be enlarged or reduced by user action without external power, utilizing elastic materials to contract and adjust the panel's size, and incorporating a guide roll and frame structure for compact folding and image differentiation across regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass substrate is used for display apparatus, then heat resistance and durability are improved, but thinness and flexibility are worsened
Solution Approach 1:
The patent replaces the traditional glass substrate with a flexible plastic substrate, enabling the display apparatus to achieve thinness and flexibility while maintaining structural integrity. The plastic substrate allows the device to be bent and folded without breaking, directly resolving the contradiction between durability and thinness.
2Strength
If glass substrate is used for display apparatus, then structural strength is improved, but flexibility and portability are worsened
Solution Approach 1:
The patent employs a plastic substrate that provides both flexibility and sufficient structural strength through its material properties and structural design. The flexible substrate enables the display to be bent and folded while maintaining adequate strength to protect internal components, resolving the contradiction between structural strength and flexibility.
3Area of moving object
If display panel size is increased, then display area is improved, but portability and ease of operation are worsened
Solution Approach 1:
The patent implements a flexible display panel that can dynamically change its configuration between expanded and folded states. When expanded, it provides a large display area; when folded, it becomes compact and portable. This dynamic transformation capability resolves the contradiction between display area and portability.
Solution Approach 2:
The patent designs the display panel to be foldable and nestable within itself, allowing the large display area to be compacted into a small portable form factor. The nested configuration enables the display to fit into smaller spaces while maintaining its full display capability when deployed.
4Measurement precision
If separate driving power is used for panel adjustment, then control precision is improved, but device complexity and weight are worsened
Solution Approach 1:
The patent employs an elastic member that automatically restores the display panel to its original position after folding or expansion. This self-restoring mechanism eliminates the need for complex motorized driving systems, reducing device complexity and weight while maintaining adequate control through simple user manipulation.
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
Enables convenient size adjustment and increased portability by allowing the display panel to be enlarged or reduced with user effort, enhancing usability and user satisfaction through flexible size adaptation and compact design.
Implementation Method 1
a member of elastic material connected to the first connection rod and to the second connection rod, wherein the member of elastic material contracts based on an elastic restoring force to decrease a separation distance between the first connection rod and the second connection rod

AI summary
A display apparatus includes a display panel, a body to which the display panel is movably coupled, a first connection part connecting the body to the display panel, a second connection part disposed apart from the first connection part to connect the body to the display panel, and an elastic part elastically connected between the first connection part and the second connection part. Accordingly, the display panel may be enlarged and reduced with only an action of a user's hand by using the elastic part without a separate driving power, and thus, a total size and weight may decrease, thereby increasing the convenience of keeping and movement.
