Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving flatness and ease of assembly due to frame imperfections, leading to visible borders and difficulty in detachment for repair or replacement.
Innovation Solution
A display device design utilizing binders and coupling members to adjust panel flatness independently of frame flatness, allowing easy attachment and detachment, and improving adhesion reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If foam tape is disposed on the entire surface of the frame to attach the display panel and the frame, then flatness compensation is improved, but ease of repair deteriorates
Solution Approach 1:
The adhesive member is divided into multiple discrete adhesive pieces positioned at specific locations rather than covering the entire frame surface. This segmentation allows the display panel to be detached by removing individual adhesive pieces, significantly improving ease of repair while still providing sufficient flatness compensation at the critical attachment points.
Solution Approach 2:
Adhesive members are strategically positioned at specific locations where flatness compensation is most needed, rather than uniformly distributing adhesive across the entire frame surface. This local quality approach maintains flatness at critical areas while reducing overall adhesive coverage to facilitate easier detachment and repair.
2Ease of manufacture
If the frame has low flatness, then manufacturing cost is reduced, but display quality deteriorates
Solution Approach 1:
A separate adhesive member is introduced as an intermediary component between the frame and display panel. This adhesive member provides the necessary flatness compensation without requiring the frame itself to have high flatness, allowing manufacturers to use lower-cost frames while maintaining display quality.
Solution Approach 2:
The flatness compensation function is segmented from the frame structure and assigned to a separate adhesive member. This allows the frame to be manufactured with lower precision at reduced cost, while the adhesive member provides the necessary flatness adjustment at the attachment points.
3Manufacturing precision
If adhesive member covers entire frame surface, then flatness compensation is improved, but adhesion reliability deteriorates
Solution Approach 1:
The continuous adhesive coverage is segmented into discrete adhesive pieces positioned at specific locations. This segmentation prevents the adhesive from covering the entire frame surface, reducing the risk of widespread adhesion failure while maintaining reliable attachment at the critical positioned points where flatness compensation is needed.

AI summary
The display device may include a display panel and a frame disposed on a rear surface of the display panel. The display device also includes a plurality of binders fixed to the rear surface of the display panel and disposed between the display panel and the frame, and a plurality of coupling members penetrating through the frame and coupled to the plurality of binders. Therefore, the flatness of the display panel attached to the plurality of binders may be improved by adjusting the locations of the frame and the plurality of binders. Also, the display panel and the frame may be easily attached and detached using the plurality of binders and the plurality of coupling members.
