LCD Bezel Design for Thin Profile and Aesthetic Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD devices face limitations in minimizing thickness and achieving aesthetically appealing designs due to the use of separate cases and covers, which increase thickness and restrict design flexibility.
Innovation Solution
The design eliminates the separate upper case by using a guide frame and rear and front set covers to accommodate the liquid crystal panel and backlight unit, with the bezel part of the front set cover facing the side of the upper substrate, thereby minimizing thickness and enhancing the sense of beauty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If separate upper case and lower case are used for manufacturing the module, then the structural stability is improved, but the thickness of the LCD device is increased
Solution Approach 1:
The patent merges the upper case and lower case into a single integrated case structure. The case includes a bottom wall forming the lower case and four side walls extending upward from the bottom wall to form the upper case, eliminating the need for separate upper and lower case components while maintaining structural stability and reducing overall thickness.
Solution Approach 2:
The single case structure serves multiple functions: it provides structural support, defines the module boundaries, and integrates the functions previously performed by separate upper and lower cases. The case also works in conjunction with the front cover to provide complete enclosure and protection.
2Reliability
If separate lower cover and upper cover are used for manufacturing the complete product, then the protection function is improved, but the thickness is increased and design flexibility is reduced
Solution Approach 1:
The patent combines the lower cover and upper cover into a single integrated case structure with integrated side walls, reducing the number of components and overall thickness while maintaining the protective enclosure function.
Solution Approach 2:
While merging the case components, the patent maintains functional segmentation by keeping the front cover as a separate removable component, allowing access to internal elements while maintaining protection when closed.
3Strength
If the upper cover is protrusion-molded at the edge, then the structural integrity is improved, but the design variety is limited and thickness is increased
Solution Approach 1:
The case integrates the side walls as integral parts of the single case structure rather than as separate protrusion-molded elements, maintaining structural integrity through the unified design while enabling greater design flexibility and variety.
Solution Approach 2:
The patent changes the geometric parameters of the case structure by using vertical side walls that extend upward from the bottom wall, creating a different structural configuration that maintains integrity while allowing for varied designs and reduced thickness.
