Adjustable Bezel Tape for Display Panel Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame-shaped fixing tapes are not adaptable to liquid crystal display panels of various sizes, limiting their applicability.
Innovation Solution
A panel unit and display device design utilizing double-sided tapes with convexo-concave portions, allowing for adjustable frame sizes to accommodate different panel sizes, while maintaining a secure attachment and preventing foreign objects from entering through slits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a frame-shaped fixing tape is prepared integrally as a single piece, then it can provide a surrounding frame shape, but it cannot be adjusted to accommodate panels of various sizes
Solution Approach 1:
The frame-shaped fixing structure is divided into multiple separate double-sided tape pieces arranged in a frame configuration rather than using a single integral piece. This segmentation allows each tape piece to be independently sized and positioned, enabling adaptation to various panel sizes while maintaining the overall frame shape functionality.
2Adaptability or versatility
If slits are provided between adjacent double-sided tapes, then foreign objects can enter through the slits, but making the tapes adjustable in size requires separate pieces that create slits
Solution Approach 1:
The opposing faces of adjacent double-sided tapes are formed with convexo-concave portions featuring curved surfaces. The convex portions protrude while concave portions recess, creating an interlocking fit that eliminates gaps and slits between tapes. This curved surface design prevents foreign objects from entering while maintaining the adjustable size capability of the segmented structure.
3Object-affected harmful factors
If convexo-concave portions are provided on opposing faces of adjacent tapes, then foreign objects are prevented from entering, but the manufacturing complexity increases
Solution Approach 1:
The convexo-concave portions are formed directly on the thin double-sided tape material itself rather than requiring separate complex mechanical components. This approach integrates the foreign object protection feature into the tape structure, utilizing the flexibility and thin-film nature of the adhesive material to create the convexo-concave profile, thereby reducing manufacturing complexity.

AI summary
A panel unit includes: a bezel including a frame-shaped section that surrounds an opening like a frame; a panel opposing the frame-shaped section; and a first double-sided tape and a second double-sided tape that are disposed adjacent to each other between the frame-shaped section and the panel to fixedly attach the frame-shaped section and the panel together, wherein the first double-sided tape has a first opposing face opposing the second double-sided tape, and the second double-sided tape has a second opposing face opposing the first opposing face, each of the first and second opposing faces having at least one convexo-concave portion. This structure provides a panel unit including a double-sided tape that provides a surrounding frame shape that is adjustable in size in accordance with a panel size.
