Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frameless liquid crystal displays face challenges in securely fixing the liquid crystal display panel without damaging it during disassembly, leading to high maintenance costs and potential damage.
Innovation Solution
A frameless liquid crystal display device design featuring a single-side attaching section with fabric strip-like fastening segments and a central attaching portion, which engages through holes in the mold frame, along with a surface decoration and screws for secure fixation, allowing for easy removal and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If double-sided adhesive tape is used to bond the liquid crystal display panel to the mold frame, then the liquid crystal display panel can be securely fixed, but the adhesive tape becomes difficult to remove during disassembly and may damage the panel
Solution Approach 1:
The fixing mechanism is divided into multiple fabric strip-like fastening segments that can be independently removed through through-holes in the mold frame, separating the bonding function from the removal function. This allows strong fixation during operation while enabling easy removal by simply pulling the fabric strips through the holes without applying force to the panel itself.
2Reliability
If strong adhesive is used to fix the liquid crystal display panel, then secure fixation is achieved, but maintenance cost increases due to potential panel damage during disassembly
Solution Approach 1:
Fabric strip-like fastening segments serve as an intermediary between the liquid crystal display panel and the mold frame. These fabric strips provide the necessary fixation strength while being easily removable through the through-holes, eliminating the need for strong adhesives that would damage the panel during maintenance and thereby reducing maintenance costs.
3Stability of the object's composition
If the liquid crystal display panel is fixed with strong bonding, then secure mounting is achieved, but the structure becomes complex and difficult to disassemble
Solution Approach 1:
The fixing system is segmented into multiple fabric strip-like fastening segments that can be individually accessed and removed through through-holes in the mold frame. This segmentation simplifies the disassembly process significantly, as each fabric strip can be pulled through its corresponding hole independently, avoiding complex disassembly procedures while maintaining stable mounting during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a removable and easily installable liquid crystal display panel, reducing maintenance expenses and preventing damage during panel replacement.
Implementation Method 1
The fabric strip-like fastening segments extend through the through holes of the mold frame to engage and fasten each other so as to fix the upper portion of the liquid crystal display panel to the mold frame
Implementation Method 2
The central attaching portion is bonded to a back surface of the liquid crystal display panel

AI summary
A frameless liquid crystal display device includes a rear enclosure, a backlight module arranged inside the rear enclosure, a mold frame arranged on the backlight module and mounted to the rear enclosure, and a liquid crystal display panel arranged on the mold frame. The liquid crystal display panel has an upper portion mounted to the mold frame through a single-side attaching section, which comprises a central attaching portion bonded to the liquid crystal display panel and two fabric strip-like fastening segments extending from the central attaching portion. The mold frame forms through holes through which the fabric strip-like fastening segments extend to engage and fasten each other so the fix the upper portion of the liquid crystal display panel to the mold frame. The liquid crystal display panel forms a step and a surface decoration is positioned on the step and fixed to the mold frame.
