Stepwise Supporting Base for Integrated Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices require separate components for the backlight module and display panel, leading to complex assembly processes and high manufacturing costs due to the need for multiple elements.
Innovation Solution
A supporting base with stepwise structures that integrates the light guide plate and display panel, reducing the number of components by using a bottom plate with alternately arranged raising and supporting segments made of light reflective material, which replaces the back bezel and inner frame, simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate components (back bezel and inner frame) are used to bear the backlight module and display panel, then structural support is provided, but device complexity increases and assembling efficiency decreases
Solution Approach 1:
The patent combines the back bezel and inner frame into a single integrated supporting base with stepwise supporting structures. This merging of previously separate components reduces the total number of parts and simplifies the assembly process, directly addressing the contradiction between device complexity and assembling efficiency
Solution Approach 2:
The supporting base serves multiple functions simultaneously: it provides structural support for both the backlight module and display panel, acts as a reflective surface through its light reflective material coating, and integrates positioning features for component alignment. This multi-functionality eliminates the need for separate dedicated components for each function
2Strength
If separate components (back bezel and inner frame) are used, then structural support is provided, but manufacturing cost increases
Solution Approach 1:
By merging the back bezel and inner frame into one integrated supporting base, the patent reduces manufacturing costs associated with producing, inventorying, and assembling multiple separate components while maintaining the required structural support through the stepwise supporting structures
3Productivity
If a single supporting base is used to integrate backlight module and display panel, then assembling efficiency improves, but structural strength may be compromised
Solution Approach 1:
The supporting base is divided into multiple stepwise supporting structures with raising segments and supporting segments, each providing localized support functions. This segmentation allows the single base to maintain adequate structural strength at multiple critical points while still achieving the goal of reduced component count and improved assembly efficiency
Solution Approach 2:
Different regions of the supporting base have different thicknesses and configurations tailored to their specific support requirements. The stepwise structures provide enhanced support where needed while maintaining overall structural integrity, ensuring that the integrated design does not compromise structural strength
4Illumination intensity
If light reflective material is used in the supporting base, then reflectivity improves, but material cost increases
Solution Approach 1:
The patent applies a light reflective material coating to the supporting base, changing the optical parameters of the base material to achieve improved reflectivity. This parameter change enhances the illumination characteristics of the display device while the coating process remains cost-effective compared to using inherently reflective metals

AI summary
A supporting base includes a bottom plate and a plurality of stepwise supporting structures connected with and raised up from a plurality of side edges of the bottom plate. Each stepwise supporting structure includes a plurality of raising segments and at least one supporting segment. The plurality of raising segments and the at least one supporting segment are alternately arranged. The at least one supporting segment is substantially parallel to the bottom plate. The lowest raising segment has a bottom end connected with one of the side edges of the bottom plate. A thickness of at least one of the at least one supporting segment is greater than that of at least one of the plurality of raising segments. A display device using the support base is also provided to improve assembling efficiency and reduce cost.
