Multi-Panel Display Support Structure for Flatness and ESD Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display devices face challenges in maintaining high dimensional precision, particularly in achieving flatness of display panels, due to large holder sizes and material limitations. Additionally, these devices are prone to electrostatic discharge issues and complex assembly processes.
Innovation Solution
The proposed display device incorporates rear supports connected via a resin connector, with a translucent cover plate fastened to the front of the rear supports. This configuration allows for high precision in maintaining the flatness of display panels and inhibits the spread of electrostatic discharge. The method of production involves insert molding to form a resin frame and connector, simplifying the assembly process and enabling flexible arrangement of display panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large holder is used to retain multiple display panels, then the display panels can be held together, but it becomes difficult to maintain high dimensional precision and flatness
Solution Approach 1:
The holder is divided into multiple separate holding portions, each capable of independently retaining a display panel. This segmentation allows each portion to maintain high dimensional precision while collectively holding multiple panels, resolving the contradiction between holding capacity and precision maintenance.
2Ease of manufacture
If the holder is formed of a resin material, then it can be manufactured easily, but bending or warping occurs during molding making it difficult to achieve uniform product quality
Solution Approach 1:
The holder is segmented into multiple independent holding portions that can be manufactured separately with consistent quality. This segmentation reduces the overall molding complexity and minimizes warping issues while maintaining ease of resin manufacturing.
Solution Approach 2:
The holding portions are designed with pre-determined geometric shapes that inherently resist warping during molding. By preliminarily designing the structure to accommodate resin material characteristics, uniform product quality is achieved while maintaining manufacturing ease.
3Manufacturing precision
If the holder is formed of a metal material, then dimensional precision can be improved, but electrostatic discharge can spread through the holder affecting multiple display panels
Solution Approach 1:
Different materials are used for different portions of the holder structure. Metal materials are used in areas requiring high dimensional precision, while resin or insulating materials are used in areas where electrostatic discharge prevention is critical. This local differentiation resolves the contradiction between precision and ESD protection.
4Adaptability or versatility
If a curved holder is used, then the display device can accommodate curved arrangements, but the cover plate must be curved in advance making the assembly process complex
Solution Approach 1:
The curved holder is segmented into multiple independent holding portions that can be manufactured as flat components. These segments are then assembled to form the curved configuration, eliminating the need to pre-curve the cover plate and simplifying the assembly process while maintaining curved arrangement capability.
