3D Display Frame Structure with Interlaced Convex Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D liquid crystal displays, the frame glue between the color filter substrate and the thin-film transistor substrate separates under horizontal shear stress due to misalignment and increased weight, leading to abnormal display performance during shock tests.
Innovation Solution
A frame structure with rubber walls of varying widths at different positions is designed to disperse forces evenly, featuring convex and concave sections that interlace along the sidewalls to distribute stress uniformly and prevent glue separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the edges of the 3D actuation element and the display panel are not aligned, then a distance exists between the edge of the 3D actuation element and the edge of the display panel, but the frame glue separates under horizontal shear stress during shock test
Solution Approach 1:
The frame structure employs convex and concave sections at specific locations along the sidewalls, creating local variations in width. These localized structural features concentrate and distribute stress at critical points, preventing the frame glue from separating under horizontal shear stress during shock tests, thereby resolving the adhesion reliability issue without requiring perfect alignment.
2Strength
If the frame glue is adhered between the color filter substrate and the thin-film transistor substrate, then the substrates are bonded together, but the frame glue separates under increased weight and shock test conditions
Solution Approach 1:
The frame structure is segmented into multiple sections including convex and concave portions along the sidewalls. This segmentation creates multiple stress distribution points that collectively resist the horizontal shear stress generated by the increased weight of the 3D actuation element during shock tests, preventing frame glue separation while maintaining strong adhesion.
3Ease of manufacture
If a uniform width frame structure is used, then the manufacturing is simple, but the force is not distributed evenly causing glue separation
Solution Approach 1:
The frame structure incorporates convex and concave sections at specific locations rather than maintaining uniform width throughout. These localized structural variations are designed to optimize stress distribution at critical points where the 3D actuation element contacts the frame, preventing glue separation while remaining compatible with existing manufacturing processes.

AI summary
A display and a frame structure thereof are disclosed. The frame structure includes a first sidewall, at least one first convex, and at least one second convex. The first sidewall includes at least one first wall section and at least one second wall section. The first wall section and the second wall section are closely distributed along an extension direction of the first sidewall. The at least one first convex protrudes on a part of an inner surface of the first wall section. The at least one second convex protrudes on a part of an inner surface of the second wall section. A protruding position of the first convex is closer to a wall foot of the first sidewall than a protruding position of the second convex.
