Backlight Module Quantum Tube Bending for Narrow Frame
Solution Overview
Problem
Traditional backlight modules with quantum tubes face issues of failure edges that increase the side frame width, making it difficult to achieve a narrow frame design while maintaining high color gamut in liquid crystal display devices.
Innovation Solution
A backlight module design featuring a quantum tube with bending sections at its ends, positioned away from the incident surface, and aligned parallel to lamp sources, which are fixed using double-side tape, allowing for a compact structure that prevents failure edge issues and maintains high color gamut without increasing the side frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If quantum tubes are installed between lamp sources and light guide plate to improve color gamut, then color gamut is improved, but side frame width increases due to failure edges
Solution Approach 1:
The quantum tube ends are bent from a linear arrangement to a curved configuration, changing the spatial dimension of the failure edges. By bending the quantum tube ends away from the incident surface direction, the failure edges are relocated to the side surfaces of the light guide plate rather than extending to the incident surface, thus preventing side frame width increase while maintaining color gamut improvement
Solution Approach 2:
The bending sections are extracted from the main body of the quantum tube and positioned separately at the side surfaces of the light guide plate. This separation removes the failure edges from the critical incident surface area, allowing the quantum tube to maintain its color enhancement function without compromising the narrow frame design

Function Achieved in This Case
This design effectively prevents failure edge issues and allows for a narrow frame arrangement by positioning the bending sections of the quantum tube away from the incident surface, ensuring high color gamut and reducing the side frame width of the backlight module.
Implementation Method 1
the quantum dot is quasi-zero-dimensional nano material, and constructed by a small amount of atoms; the diameters are generally between 1-10 nm. Because the electrons and holes are in quantum confinement, and the continuous energy band structure becomes the discrete energy level structure with molecule property, which can irradiate fluorescent light after being excited and then can change the color gamut of the coming light.
