Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display backlight modules face challenges in improving color saturation due to limitations in the installation and performance of traditional light sources, such as Cold Cathode Fluorescent Lamps and Light Emitting Diodes, which do not accommodate quantum bars effectively.
Innovation Solution
A light bar comprising a circuit board with blue light emitting diodes, a quantum tube, and double-side tapes for secure fixation, where the blue light excites the quantum tube to generate red and green lights, producing white light with enhanced chromaticity, and silk screens to prevent hotspot phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light sources (CCFL or LED) are used in the backlight module, then the installation is simple and the structure is mature, but the chromaticity and color saturation cannot be sufficiently improved
Solution Approach 1:
The patent introduces a quantum tube as an intermediary component between the light source and the display panel. The quantum tube converts the light from traditional LED or CCFL sources into light with improved chromaticity, allowing the use of mature light sources while achieving enhanced color saturation. This mediator approach resolves the contradiction by decoupling the light source selection from the chromaticity requirement.
Solution Approach 2:
The patent employs quantum dots (quantum tube) with specific material properties to convert light wavelengths. By using composite material structure (quantum tube containing quantum dots), the system achieves improved chromaticity while maintaining compatibility with traditional light sources, thus resolving the contradiction between chromaticity improvement and installation compatibility.
2Illumination intensity
If quantum bar is installed to improve chromaticity, then the color saturation is enhanced, but the installation requires particular conditions and traditional installation methods do not apply
Solution Approach 1:
The patent segments the quantum tube installation from the traditional light source installation process. The quantum tube is installed in a separate, simplified manner that does not require the complex positioning and mounting procedures needed for traditional LEDs or CCFLs. This segmentation reduces installation complexity while maintaining the chromaticity improvement benefits.
Solution Approach 2:
The quantum tube serves as an intermediary that simplifies the overall installation process. Rather than requiring precise installation of complex quantum bar structures, the quantum tube can be installed using simpler methods, reducing the particular installation conditions and complexity while still achieving the desired color saturation enhancement.
3Reliability
If quantum tube is fixed securely on the circuit board, then the stability and reliability are improved, but the ease of rework and reassembly is reduced
Solution Approach 1:
The patent employs a dynamic fixation approach where the quantum tube is secured with appropriate fastening mechanisms that balance stability and removability. The fixation method provides sufficient stability for reliable operation while allowing for convenient removal and reinstallation when rework is needed, resolving the contradiction between fixation stability and rework convenience.
