Flexible Tape Assembly for Thin LCD Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal displays (LCDs) with rigid frames restrict flexibility and increase volume, limiting their application in various digital products due to the inflexibility and excessive thickness of the frame, especially when the light guide plate becomes thinner.
Innovation Solution
A flexible LCD design that uses a tape to wrap the display assembly, eliminating the need for a conventional frame, thereby reducing parts and simplifying the assembly process, and incorporating a tape with a peripheral and bending portion to attach to the edges and surfaces of the display assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional rigid frame is used to fix and protect the light source assembly, then the structural integrity and protection are improved, but the flexibility and volume are worsened
Solution Approach 1:
The patent replaces the rigid frame with a flexible tape that wraps around the light source assembly. The tape has sufficient strength to hold the assembly together while being flexible enough to allow bending and conforming to different shapes, thus resolving the contradiction between structural integrity and flexibility.
Solution Approach 2:
The patent removes the conventional rigid frame from the light source assembly structure. By extracting this problematic component and replacing it with a flexible alternative, the patent eliminates the source of the contradiction while maintaining the necessary protective and structural functions.
2Strength
If a conventional rigid frame is used to fix and protect the light source assembly, then the structural integrity and protection are improved, but the volume is worsened
Solution Approach 1:
The flexible tape used in the patent has minimal thickness compared to a rigid frame, providing necessary structural support while occupying minimal volume. This thin-film approach resolves the contradiction between maintaining structural integrity and minimizing volume.
Solution Approach 2:
By removing the conventional rigid frame and its associated volume, the patent significantly reduces the overall volume of the light source assembly while maintaining protective and structural functions through the compact flexible tape.
3Volume of stationary object
If the light guide plate is made thinner to reduce volume, then the volume and profile are improved, but the flexibility is worsened when below 0.3mm thickness
Solution Approach 1:
The patent combines the ultra-thin light guide plate with other components into an integrated light source assembly that is wrapped by a flexible tape. This merging allows the thin plate to maintain its volume advantages while the surrounding flexible structure provides the necessary flexibility and protection.
Solution Approach 2:
The flexible tape acts as a supporting shell that enables the ultra-thin light guide plate to bend and flex without breaking. The tape provides structural support from the outside, allowing the thin plate to achieve both reduced volume and maintained flexibility.
4Object-affected harmful factors
If a conventional frame structure with tape is used, then the light sheltering effect is improved, but the number of parts and assembly complexity are worsened
Solution Approach 1:
The patent merges the light sheltering function with the flexible tape that wraps the light source assembly. The same tape that provides structural support and flexibility also performs the light sheltering function, eliminating the need for separate frame structures and reducing the total number of parts.
Solution Approach 2:
The flexible tape in the patent serves multiple functions simultaneously: it provides structural support, enables flexibility, prevents light leakage, and protects the light source assembly. This multi-functionality reduces the number of separate components needed while maintaining all necessary functions.

Data Source
AI summary
An LCD and a method for assembling the LCD are provided. The LCD includes a display assembly and a tape. The display assembly has a top surface, a bottom surface which is opposite the top surface, and a lateral edge connected the edge of the top surface with the edge of the bottom surface. The tape comprises a peripheral portion and a bending portion extending from the peripheral portion. The peripheral portion is utilized to attach to the peripheral area of the top surface, and the bending portion is bended to attach to the lateral edge and the peripheral area of the bottom surface.
