Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a thin layer is provided on the front surface of the display panel to achieve natural appearance and touch, then the visual harmony with space is improved, but the visibility at the time of light emission is reduced
Solution Approach 1:
A transparent substrate forming a light guiding path is introduced as an intermediary component between the light emitting element and the thin layer. This light guide mediates the light transmission by efficiently conducting light straight through the thin layer to the display surface, thereby maintaining the natural appearance of the thin layer while ensuring sufficient visibility during light emission.
Solution Approach 2:
The transparent substrate is designed with specific optical properties that change light transmission characteristics. By controlling the transparency and light guiding properties of the substrate, the system maintains the aesthetic appearance of the thin layer while optimizing light transmission for visibility.
2Illumination intensity
If a light guide with through holes is used to improve visibility, then light emission visibility is improved, but the manufacturing complexity increases
Solution Approach 1:
The transparent substrate is designed with a porous structure containing micropores that form light guiding paths. This porous configuration allows light to propagate efficiently straight through the substrate without requiring complex alignment mechanisms or additional through-hole structures, thereby simplifying manufacturing while maintaining high visibility.
Solution Approach 2:
The transparent substrate combines multiple functions in a single component: it provides structural support, enables touch sensor integration, and acts as a light guide. This composite approach eliminates the need for separate light guide components with through holes, reducing manufacturing complexity while improving visibility.
3Manufacturing precision
If the light emitting element array is miniaturized to increase pixel density, then the display resolution is improved, but the light output per pixel decreases
Solution Approach 1:
The transparent substrate's light guiding properties are optimized to compensate for the reduced light output from miniaturized pixels. By adjusting the refractive index, transparency, and light guiding path design of the substrate, the system enhances the light extraction efficiency from each small pixel while maintaining high pixel density.
