Backlight Holder Structure for LCD Assembly Complexity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal displays (LCDs) face challenges in assembly complexity and error due to the large number of components, leading to increased assembly time and yield issues.
Innovation Solution
A holder structure for the backlight module with oppositely disposed holders having extension holding portions that support the display panel on four sides, reducing the number of components and weight, and incorporating a back bezel with light sources and a reflective layer for efficient assembly and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional multiple components are used to support the display panel, then the structural stability is improved, but the number of components and assembly complexity increases
Solution Approach 1:
The patent combines multiple support functions into a single holder structure. The holder integrates the display panel support function, the backlight module positioning function, and the side surface protection function into one unified component, eliminating the need for separate support brackets, positioning clips, and protective covers that would otherwise be required.
Solution Approach 2:
The holder structure serves multiple functions simultaneously: it supports the display panel from below, positions the backlight module at the rear, and protects the side surfaces of the display panel. This multi-functional design reduces the total component count while maintaining structural stability.
2Manufacturing precision
If more components are used to ensure positioning accuracy, then the manufacturing precision is improved, but the weight and cost increase
Solution Approach 1:
The holder integrates positioning features directly into its structure, eliminating the need for separate positioning clips or alignment mechanisms. The holder's geometry itself provides the positioning accuracy through its configured shape and assembly interfaces.
3Strength
If traditional assembly methods with multiple components are used, then the structural support is improved, but the assembly time and error rate increase
Solution Approach 1:
The holder consolidates multiple structural support functions into one component, reducing the number of assembly steps. Workers only need to install the holder, the display panel, and the backlight module in sequence, rather than assembling multiple separate support components.
Solution Approach 2:
The holder is pre-configured with integrated support and positioning features during manufacturing, so no additional adjustment or assembly of separate components is needed during final assembly. The holder arrives ready-to-install with all necessary geometric features already formed.

AI summary
The present invention provides a display apparatus, a backlight module and a holder structure thereof. The display apparatus comprises the backlight module and a display panel. The backlight module comprises a back bezel, at least one light source and two holders. The at least one light source light source is disposed on the back bezel. The holders are disposed at the two opposite sides of the backlight module. Each of the holders comprises two extension holding portions and a panel supporting surface. The extension holding portions are formed at two ends of each of the holders. The panel supporting surface is formed on the holders and the extension holding portions. The present invention can reduce the number of the components and the weight thereof.
