Wire-Coupled Panel Holder for Damage-Free OLED Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with self-emissive display panels, such as OLEDs, are difficult to disassemble and replace without damage due to their thin structure, which lacks a backlight unit.
Innovation Solution
A display apparatus design that allows for the detachable coupling of a display panel with a rear chassis, utilizing a panel holder and support frame coupled by a wire, enabling the display panel to be disassembled and replaced without damage.

If a self-emissive display panel (OLED) is used to achieve a thin structure, then the display apparatus thickness is reduced, but the display panel cannot be disassembled and replaced without damage
Solution Approach 1:
The display panel is divided into a front chassis portion and a rear chassis portion that can be separated from each other. The front chassis holds the display panel, while the rear chassis can be detached to enable panel replacement. This segmentation allows the thin OLED structure to be maintained while providing replaceability through modular design.
Solution Approach 2:
The coupling between the front chassis and rear chassis is made dynamic rather than fixed. A coupling member allows the rear chassis to be detachably coupled to the front chassis, enabling the display panel to be accessed and replaced by separating the chassis portions, thus providing repairability without compromising the thin structure.

If the rear cover size is reduced to achieve an ultra-slim appearance, then the display apparatus becomes thinner, but the structural integrity and support may be compromised
Solution Approach 1:
The rear cover is segmented into a first rear cover and a second rear cover that can be separated. This allows the rear cover to be designed with optimal thickness for ultra-slim appearance while maintaining structural integrity through the distributed support of multiple cover portions and their connection to the chassis structure.

AI summary
A display apparatus includes: a display panel; a rear chassis covering a rear surface of the display panel; a support frame coupled to the rear chassis; a panel holder provided on the rear surface of the display panel to face the support frame, the panel holder being configured to be coupled to the support frame to attach the display panel to the rear chassis; and a wire configured to: couple the panel holder to the support frame based on the wire being coupled to the panel holder and the support frame, and release the coupling between the panel holder and the support frame based on the wire being separated from the panel holder and the support frame.
