Serrated Frame Reflector Seam for Thin Display Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display manufacturing methods struggle to achieve a thinner, lighter, and more cost-effective design without compromising structural strength, as thin glass substrates are prone to bending and damage, and alternative materials like rubber membranes are impractical due to manufacturing temperature limitations.
Innovation Solution
The design of a display apparatus with a frame and reflector at the same level, where the frame partially supports a light guide plate and the reflector is extended to improve light utilization, featuring serrated engaging edges between the frame and reflector to enhance structural integrity and prevent drooping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If thin glass substrates (less than 0.5 mm) are used to reduce display thickness, then the display becomes thinner, but the substrate becomes prone to bending and damage
Solution Approach 1:
The patent combines the frame and reflector into a single integrated component structure, where the frame provides structural support to prevent substrate bending while the reflector performs its light-reflecting function. This merging allows the thin substrate to be supported without requiring a separate support structure, thus maintaining thinness while improving strength.
Solution Approach 2:
The frame extends in multiple dimensions to provide comprehensive support: it surrounds the substrate perimeter (horizontal dimension) and extends downward to provide structural rigidity (vertical dimension). This multi-dimensional support structure prevents bending of the thin substrate without adding significant thickness to the overall display assembly.
2Length of moving object
If the frame and reflector are designed at the same level with the frame supporting the light guide plate, then the display thickness is reduced, but the structural complexity increases
Solution Approach 1:
The frame and reflector are merged into a single integrated component, eliminating the need for separate assembly of these two parts. This reduces the number of components and assembly steps, thereby reducing structural complexity despite the enhanced functional integration.
Solution Approach 2:
The frame serves multiple functions: it provides structural support for the substrate, supports the light guide plate, and houses the reflector. This multi-functionality reduces the need for additional dedicated components, simplifying the overall structure while achieving multiple objectives simultaneously.
3Loss of energy
If the reflector is extended to improve light utilization, then light efficiency improves, but the manufacturing precision requirements increase
Solution Approach 1:
By merging the frame and reflector into a single integrated component, the reflector's position is determined during the molding process rather than requiring separate positioning and assembly. This integration reduces the need for high-precision post-assembly adjustments, lowering manufacturing precision requirements while still achieving improved light utilization through the extended reflector design.

AI summary
A display apparatus includes a panel module and a backlight module. The backlight module is disposed under the panel module. The backlight module includes a frame, a light guide plate, and a reflector. The frame supports the edge of the light guide plate. The reflector is disposed at the bottom of the light guide plate. The edge of the reflector and the edge of the frame horizontally form an engaging seam without overlapping, and the engaging seam is substantially in a serrated shape.
