Fixing Element for Display Device Bezel Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face issues with light leakage and component contamination due to the detachment of the top cover from the display panel, particularly near coupling holes, which affects the reliability and performance of the device.
Innovation Solution
A display device design that incorporates a fixing element with a coupling portion, a bent portion, and a contact portion to securely align and press against the sidewall of the top cover, preventing detachment and enhancing the fixing force between the display panel and the bezel portion, thereby reducing bezel width and preventing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coupling elements are inserted into coupling holes formed on the base cover and the top cover, then the base cover and top cover can be coupled together, but the top cover may be detached from the top surface of the display panel (especially in areas near the coupling holes), thereby causing light leakage and contamination of components contained within
Solution Approach 1:
The patent introduces a fixing element as an intermediary component between the coupling element and the top cover. This fixing element includes a contact portion that directly contacts the top surface of the display panel near the coupling holes, and a pressing portion that presses the top cover against the display panel. The intermediary fixing element ensures that the pressing force is effectively transmitted to secure the top cover, preventing detachment and light leakage while maintaining the coupling structure.
Solution Approach 2:
The patent applies local quality by concentrating the pressing force at specific locations where it is most needed - near the coupling holes on the top surface of the display panel. The contact portion of the fixing element is positioned to make localized contact with the top cover at these critical areas, ensuring that the pressing force is applied precisely where detachment is most likely to occur, rather than distributing force uniformly across the entire top cover.
2Reliability
If the top cover is securely fixed to the display panel to prevent detachment, then light leakage is prevented, but the structure becomes more complex with additional fixing elements
Solution Approach 1:
The patent merges multiple functions into a single fixing element. The fixing element simultaneously serves as a support for the coupling element, a pressing mechanism for the top cover, and a localized contact point with the display panel. By combining these functions into one integrated component rather than using separate elements for each function, the overall structural complexity is reduced while maintaining effective fixing reliability.

AI summary
A display device, comprising a base cover with a base plate, a sidewall portion extended from the base plate and a first coupling hole; a display panel with a first display portion configured to display an image and a second display portion outside and along the first display portion, a top cover with a bezel portion sized to be laid over the second display portion, and a sidewall portion extended from the bezel portion, the top cover including a second coupling hole; and a fixing element with a first coupling portion having a third coupling hole, a contact portion extended from the first coupling portion and configured to maintain contact with a portion of the top cover. A coupling element can be inserted through the first through third coupling holes so as to press the contact portion against a portion of the top cover.
