Guide Panel with Dual Partition Walls for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices, such as liquid crystal display devices, face issues with increased costs and assembly complexity due to the number of parts required for the set electronic device, including a set middle cover and a large set rear cover, which also lead to light leakage at the joints.
Innovation Solution
A display device with a guide panel featuring a dual partition wall structure and extensions that integrate with the cover bottom using a hook structure, reducing the need for additional covers and minimizing light leakage by forming the outer surface of the set electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a set middle cover and set rear cover are used to enclose and protect the display device, then the protective function is improved, but the number of parts increases leading to increased costs and assembly complexity
Solution Approach 1:
The guide panel is merged with the cover bottom to form an integrated support structure. The guide panel includes a first extension that extends from the cover bottom to cover the side surface of the display panel, combining the functions of support and protection in a single component. This reduces the number of separate parts needed while maintaining the protective function.
Solution Approach 2:
The guide panel serves multiple functions: it supports the display panel, covers the side surface for protection, and forms part of the exterior appearance. By making the guide panel multi-functional, the patent eliminates the need for separate set middle cover and set rear cover components, thereby reducing part count and assembly complexity.
2Reliability
If traditional separate cover structures are used, then adequate protection is provided, but light leakage occurs at the joints between covers
Solution Approach 1:
By merging the guide panel with the cover bottom and extending it to cover the side surface, the patent creates a continuous, seamless structure without joints between separate cover components. This eliminates the light leakage problem that occurs at joints between separate covers while maintaining adequate protection.
3Strength
If a plastic chassis or guide panel is coupled with the cover bottom to fix the display panel, then the display panel is securely mounted, but the structure becomes more complex
Solution Approach 1:
The guide panel is integrated with the cover bottom as a single molded piece, eliminating the need for separate coupling mechanisms. The first extension of the guide panel naturally provides the mounting function by covering and securing the side surface of the display panel, thereby maintaining mounting security while reducing structural complexity.

AI summary
A display device includes a display panel, a back light unit configured to provide light to the display panel, and a guide panel covering side surfaces of the display panel and the back light unit. The guide panel includes a dual partition wall structure of an inner partition wall and an outer partition wall, a first extension that is extending from and integral with the dual partition wall structure, and a second extension protruding in a direction perpendicular to the dual partition wall structure to be between the back light unit and the display panel.
