Detachable Display Bezel Structure for Repairable Narrow Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bezelless display devices face challenges in repairability due to glued components, long production cycles, and light leakage issues, which complicate disassembly and increase the risk of damage to the display panel and optical film material.
Innovation Solution
A display device design featuring a detachable middle frame assembly and bezel member, supported by a transparent glue structure, with a curved support surface and light propagation space, allowing for easy disassembly and repair, and incorporating a light shielding structure to prevent light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If components are connected by glue structure to achieve narrow bezel, then display appearance is improved, but repairability deteriorates and disassembly becomes difficult
Solution Approach 1:
The frame is divided into a middle frame assembly and separate bezel members. The middle frame assembly remains glued to the display panel for structural integrity, while the bezel members are detachably connected via magnetic or snap-fit mechanisms, allowing separate removal for repair without damaging the display panel.
Solution Approach 2:
The bezel members are extracted as separate detachable components from the integrated frame structure. This allows the bezel to be removed independently for repair purposes while maintaining the narrow bezel aesthetic when assembled.
2Object-affected harmful factors
If integrated frame structure is used to prevent light leakage, then display performance is improved, but production cycle time increases due to complex assembly
Solution Approach 1:
The light shielding function is segmented between the middle frame assembly (providing primary shielding) and the bezel members (providing peripheral shielding). This modular approach allows each component to be pre-assembled and tested separately, reducing final assembly time while maintaining comprehensive light leakage prevention.
3Ease of repair
If disassembly is performed to enable repair, then repairability is improved, but risk of damage to display panel and optical film material increases
Solution Approach 1:
The frame structure is segmented into a stable middle frame assembly that remains attached to the display panel and detachable bezel members. During repair, only the bezel members need to be removed, leaving the display panel and optical film material undisturbed, thus eliminating damage risks associated with full disassembly.
4Shape
If narrow bezel design is implemented, then product aesthetics are improved, but structural support and stability become insufficient
Solution Approach 1:
The frame's structural support function is segmented and concentrated in the middle frame assembly, which maintains full width and rigid connection to the display panel. The bezel members provide aesthetic finishing and peripheral support, while the middle frame bears the primary structural load, ensuring stability despite the narrow overall bezel appearance.

AI summary
A display device, comprising: a display assembly, middle frame assemblies, bezel members, frame structures, and a backplane. The middle frame assemblies are located on a light incident side of the display assembly; at the edge of the display assembly, the middle frame assemblies provide support for the display assembly in the thickness direction of the display assembly, and the middle frame assemblies are connected to the display assembly by the frame structures in the thickness direction of the display assembly; the distance from the middle frame assemblies to the display assembly is greater than 0 in the thickness direction of the display assembly; the backplane is located on the side of the middle frame assemblies distant from the display assembly; and the bezel members are located on the periphery of the display assembly and the peripheries of the middle frame assemblies, and are detachably connected to the middle frame assemblies.
