Display Device Rear Case Ribs for Structural Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices, particularly liquid crystal display panels, face challenges in efficiently integrating and securing components such as backlight units, controllers, and optical sheets, which affect the structural rigidity and light distribution, leading to potential issues with image quality and durability.
Innovation Solution
The design incorporates a rear case with extended ribs and a boss system that supports the backlight unit, a controller, and optical sheet, along with a plate that covers and fixes these components, enhancing structural integrity and light distribution by providing a secure and efficient assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If components are integrated using conventional mounting methods, then assembly is simpler, but structural rigidity and component security are insufficient
Solution Approach 1:
The patent integrates multiple support functions into a single rear case structure by extending ribs directly from the rear case body to contact the backlight unit. This merging of support and mounting functions into one integrated structure simultaneously improves structural rigidity while avoiding the need for separate complex mounting mechanisms.
Solution Approach 2:
The patent extends support ribs in the depth dimension from the rear case front surface to contact the backlight unit, creating a three-dimensional support structure. This dimensional approach provides enhanced structural rigidity and component security without requiring additional lateral or vertical assembly complexity.
2Reliability
If multiple components are secured with separate mounting structures, then component security is improved, but integration efficiency and assembly time increase
Solution Approach 1:
The rear case is designed with multiple ribs extending from its front surface that can simultaneously contact and secure multiple different components including the backlight unit, controller, and optical sheets. This multi-functional design provides reliable component security while enabling single-step assembly operations that improve productivity.
Solution Approach 2:
The patent divides the support function into multiple discrete ribs extending from the rear case, each rib providing independent contact points for different components. This segmentation allows each component to be securely mounted at optimal locations while maintaining assembly efficiency through the unified rear case structure.
3Productivity
If components are loosely mounted, then assembly is faster, but image quality and durability suffer due to poor structural support
Solution Approach 1:
The rear case ribs are pre-formed as integral structures during rear case manufacturing, positioned at optimal locations for component contact. This preliminary action ensures that when components are assembled, they are immediately positioned with high precision for optimal image quality, while the assembly process itself remains fast due to the pre-positioned support structures.
