Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel display apparatuses using glass substrates face limitations in achieving thinness, weight-lightness, and flexibility, which restrict their ability to be bent, rolled, or folded, limiting their usability and portability.
Innovation Solution
A flexible display apparatus with a display panel divided into regions, supported by a housing and a frame that can stretch or contract, allowing the display area to be enlarged or reduced without external power, using elastic members and a stopper mechanism for user-controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a glass substrate is used for the display apparatus, then high heat endurance during manufacturing is achieved, but thinness, weight-lightness, and flexibility are limited
Solution Approach 1:
The patent changes the material parameter from glass to plastic substrate, fundamentally altering the thermal, mechanical, and weight properties of the display apparatus. This parameter change enables the display to achieve flexibility and weight reduction while maintaining manufacturing feasibility through adjusted processing conditions suitable for plastic materials.
Solution Approach 2:
The patent employs a plastic substrate that can be replaced or disposed of more easily than glass, aligning with the principle of using less durable but more convenient materials for applications where flexibility and weight are prioritized over long-term heat resistance and durability.
2Temperature
If a glass substrate is used for the display apparatus, then manufacturing heat resistance is maintained, but flexibility and bendability are restricted
Solution Approach 1:
The patent changes the substrate material parameter from glass to plastic, which fundamentally alters the mechanical properties to enable bending and flexibility while accepting reduced heat resistance. This parameter change allows the display to adapt to various forms and applications requiring flexibility.
Solution Approach 2:
The patent employs a plastic substrate that functions as a flexible shell or film, enabling the display apparatus to be bent, folded, or shaped according to different application requirements, thus achieving the flexible shell principle.
3Area of stationary object
If the display area is enlarged, then display performance is improved, but total size and weight increase
Solution Approach 1:
The patent employs a retractable display panel that can dynamically change its extended length between a first length (enlarged display area) and a second length (reduced size). This dynamic configuration allows the display area to be enlarged when needed while reducing the overall size and weight for portability when the display area is retracted.
Solution Approach 2:
The patent introduces a temporal dimension to the display area by allowing it to change size over time through retraction and extension. The display panel can transition between different spatial configurations, effectively using time as an additional dimension to manage the trade-off between display area and portability.
4Ease of operation
If the display apparatus is made portable, then usability is improved, but structural stability and support are compromised
Solution Approach 1:
The patent employs a dynamic frame structure that can change its configuration between extended and retracted states. When the display panel is retracted to its second length, the overall size and weight are reduced for portability, while the frame maintains structural stability through its adjustable design that can provide support in both configurations.
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 area to be expanded or reduced manually, reducing total size and weight, enhancing usability and movement convenience.
Implementation Method 1
an elastic part elastically connected between the fixing part and the sliding part to support the third region of the display panel

AI summary
A flexible display apparatus includes a display panel including a first region, a second region, and a third region between the first region and the second region, a housing movably supporting the display panel, and a frame movably disposed in the housing to stretch or contract based on movement of the display panel, wherein the frame includes a fixing part fixed to the housing to movably support the first region of the display panel, a sliding part coupled to the second region of the display panel and movably disposed in the housing, and an elastic part elastically connected between the fixing part and the sliding part to support the third region of the display panel. Accordingly, a display area may be enlarged and reduced with only an action of a user's hand by using a frame without a separate driving power, and thus, total size and weight may decrease, thereby increasing the convenience of keeping and movement.
