Borderless Display Panel Guide with Dual Coupling Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel image display devices with a clear borderless design face issues such as light leakage and complex assembly processes due to direct fixation of the image display panel, leading to deformation under external pressure or impact, and compromised process yield.
Innovation Solution
A dual coupling structure is implemented, where the panel fixing portion and guide frame are movable in x, y, and z axis directions, allowing the image display panel to be attached without a separate case, and a bottom case is fixed to the panel guide to cover the back surface, enhancing stability and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the image display panel is directly fixed to the guide bracket or assembly structure, then the assembly process is simplified, but the panel and assembly structure deform under external pressure or impact, causing light leakage and faults
Solution Approach 1:
The guide bracket is divided into a first guide bracket and a second guide bracket that are separately assembled to the image display panel. This segmentation allows each bracket to independently support specific edges of the panel, distributing mechanical stress and preventing deformation under external pressure while maintaining assembly simplicity.
2Device complexity
If the image display panel is directly fixed to the assembly structure, then the device structure is simplified, but assembly and disassembly processes become complicated, deteriorating process yield
Solution Approach 1:
The guide bracket is segmented into two separate brackets that can be independently assembled and disassembled. This segmentation simplifies the assembly process by allowing separate attachment of each bracket to the panel edges, improving process yield while maintaining overall structural simplicity.
Solution Approach 2:
The first and second guide brackets are pre-assembled to the image display panel before final assembly with the backlight unit and other components. This preliminary action ensures proper panel positioning and support is established early in the assembly process, facilitating subsequent assembly steps and improving overall process efficiency.
3Reliability
If a separate adhesive means or fixing means is used to fix the panel, then the panel can be secured, but the assembly process becomes complicated and process yield deteriorates
Solution Approach 1:
The invention extracts and eliminates the need for separate adhesive means or fixing means by using the first and second guide brackets that mechanically support and secure the image display panel through their structural design, thereby simplifying the assembly process and improving process yield while maintaining secure panel fixation.
