Backlight Metal Frame Bending Part Blocks Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules for liquid crystal displays often suffer from light leakage, especially when used in irregularly-shaped displays with hollowed-out regions for features like cameras, which can affect the optical performance of these features.
Innovation Solution
A display module design featuring a backlight module with a metal frame that includes a bending part extending into hollowed-out areas, preventing light from leaking out and ensuring optimal optical performance by blocking light beams with an opaque first bending part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the backlight module uses an original structure with hollowed-out regions for cameras, then the display can accommodate camera features, but light emitted by the backlight module leaks out to camera positions and affects optical effect
Solution Approach 1:
The metal frame is segmented into a main body portion and a bending portion. The bending portion is specifically designed to extend into the hollowed-out region, creating a segmented structure that addresses light leakage in specific areas while maintaining the overall frame integrity and camera accommodation functionality.
Solution Approach 2:
The bending portion of the metal frame is specifically positioned to extend into the hollowed-out region where light leakage occurs. This local structural modification targets the specific problem area (camera hollowed-out region) with an opaque material to block light, while the rest of the frame maintains its original light-permeable properties for normal display function.
2Object-affected harmful factors
If the metal frame uses a bending portion extending into hollowed-out areas, then light leakage is prevented, but the structural complexity increases
Solution Approach 1:
The bending portion is integrated as part of the metal frame structure rather than being a separate component. This merging of the light-blocking function into the existing frame structure prevents light leakage while minimizing the increase in overall device complexity, as no additional separate parts are required.
Solution Approach 2:
Instead of adding separate light-blocking components within the hollowed-out regions, the solution inverts the approach by making the frame itself extend into these regions. The metal frame structure is inverted or bent to reach into the hollowed-out areas, using the frame's own structure to perform the light-blocking function.
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
The solution effectively reduces light leakage to areas like camera positions, enhancing the display's performance and user experience by maintaining high light utilization efficiency while accommodating irregular shapes without compromising structural integrity.
Implementation Method 1
The first bending part is disposed on inner sidewalls of the at least one second hollowed-out part and is opaque. The first bending part intersects a plane for the main part; and one end of the first bending part away from the main part extends inside the at least one first hollowed-out part.
