Serrated Frame Reflector Seam for Thin Display Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display manufacturing methods struggle to achieve a thinner, lighter, and more robust design due to substrate bending and breakage issues, with existing thinning techniques either compromising structural strength or increasing production costs.
Innovation Solution
The design of a display apparatus with a frame and reflector at the same level, where the frame partially extends to support the light guide plate and the reflector is extended to improve light utilization, featuring serrated engaging edges 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 substrates are prone to bending and damage
Solution Approach 1:
The patent applies this principle by using a thin film encapsulation layer (organic and inorganic layers) to protect the light-emitting elements, allowing the display to achieve thinness while maintaining structural integrity through the flexible yet protective film structure
Solution Approach 2:
The patent uses composite materials by combining organic encapsulation layers with inorganic encapsulation layers to create a multi-layer protective structure that provides both flexibility and strength, resolving the contradiction between thinness and durability
2Length of moving object
If the thickness of one substrate is etched to 0.1-0.2 mm to reduce display thickness, then the display becomes thinner, but the manufacturing cost increases
Solution Approach 1:
The patent changes the parameter of encapsulation structure from traditional thick glass substrates to thin film encapsulation with specific thickness ranges (organic layer: 50-500 nm, inorganic layer: 10-200 nm), achieving thinness without complex etching processes
Solution Approach 2:
The patent replaces the mechanical etching process with a chemical vapor deposition and atomic layer deposition process to form encapsulation layers, substituting mechanical removal of material with controlled chemical deposition, thereby reducing manufacturing complexity and cost
3Loss of energy
If the reflector is extended to improve light utilization, then light efficiency improves, but the overall thickness increases
Solution Approach 1:
The patent moves the light source to the edge of the display panel rather than placing it behind the substrate, changing the spatial arrangement from a vertical stacking configuration to a lateral positioning configuration. This allows the reflector to be positioned more efficiently without increasing overall thickness
Solution Approach 2:
The patent segments the display structure into distinct functional layers (substrate, light-emitting elements, encapsulation layers, color conversion layers) with the light source positioned at the edge, allowing each component to be optimized independently for both thickness and light efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the overall thickness of the display apparatus while maintaining structural strength, improving light utilization, and reducing manufacturing costs by enhancing the engaging strength between the frame and reflector.
Implementation Method 1
the reflector of the invention has light-reflecting portions that are partially extended to the light sources, so that the reflector provides a design for improving light utilization rate

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 that of the frame horizontally form an engaging seam without overlapping, and the engaging seam is substantially in a serrated shape.
