Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional backlight module is used, then the structure is simple, but the light distribution and brightness enhancement are insufficient
Solution Approach 1:
The quantum dots layer is embedded within the light guiding board structure, with the package layer enclosing the quantum dots layer inside the receiving room. This nested configuration allows the quantum dots to be integrated into the light guiding path without requiring separate external illumination systems, thereby enhancing brightness while maintaining compact structure.
Solution Approach 2:
The light guiding board acts as an intermediary component between the light source and the display panel. It incorporates the quantum dots layer and package layer to mediate light transformation and distribution, converting light from the source into enhanced display illumination through the quantum dots' luminescence properties.
2Illumination intensity
If quantum dots layer is added to enhance brightness, then illumination intensity improves, but device complexity increases
Solution Approach 1:
The quantum dots layer, package layer, and light guiding board are merged into a single integrated structure. The package layer is coupled to the light guiding board and encloses the quantum dots layer, creating a unified component that performs multiple functions: light guidance, quantum dots protection, and brightness enhancement, thereby reducing the need for separate components.
Solution Approach 2:
The light guiding board serves multiple functions simultaneously: it guides light from the source, houses the quantum dots layer for wavelength conversion, provides structural support, and works with the package layer to protect and position the quantum dots. This multi-functionality reduces the need for additional separate components.
