Simplified LCD Panel Guide and Cover Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of assembling traditional LCD devices due to numerous components limit their slimness and reduce manufacturing efficiency.
Innovation Solution
A simplified LCD device configuration is achieved by integrating the LCD panel driver, backlight driver, and system driver into a single controller, eliminating the need for a top case and bottom cover, and using a front cover with fixing portions to couple with a back cover, thereby reducing assembly steps and thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional LCD device configuration with multiple components (top case, bottom cover, front cover, rear cover) is used, then structural completeness and component protection are improved, but device complexity and assembly process complexity increase
Solution Approach 1:
The patent merges the top case and bottom cover into an integrated frame structure that provides both upper and lower support functions. This consolidation reduces the total component count while maintaining the structural protection and enclosure functions previously distributed across separate parts.
Solution Approach 2:
The integrated frame structure serves multiple functions simultaneously: it acts as both the top case and bottom cover, provides structural support, encloses the LCD panel, and serves as the mounting framework for the backlight unit. This multi-functionality eliminates the need for separate dedicated components.
2Reliability
If traditional LCD device configuration with multiple covers and cases is used, then component protection is improved, but assembly process complexity and manufacturing cost increase
Solution Approach 1:
By combining the top case and bottom cover into a single integrated frame, the patent reduces the number of assembly operations required. Instead of separately assembling multiple covers to the LCD panel and backlight unit, the integrated frame is installed as a single component, simplifying the manufacturing process.
3Stability of the object's composition
If traditional LCD device configuration with multiple combined components is used, then structural stability is improved, but device thickness increases
Solution Approach 1:
The integration of top case and bottom cover functions into a single frame structure eliminates the cumulative thickness of multiple separate components. The frame is designed to provide equivalent structural support with reduced overall thickness, achieving both slimness and stability.

AI summary
Provided is a display device with a simplified configuration. The display device includes a display panel, a panel guide, a backlight unit, a front cover, and a back cover. The panel guide supports the display panel. The backlight unit emits light to the display panel. The front cover encloses an outer surface of the display panel. The backlight unit is stored in the back cover. The front cover includes a fixing portion formed thereon projecting toward the back cover, and the back cover includes a supporting portion projecting toward the backlight unit, to fix the front cover to the back cover.
