Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light control layers are used to convert light color in different pixel areas, then color accuracy is improved, but color mixing between adjacent pixel areas occurs
Solution Approach 1:
The light control layer is segmented into first, second, and third light control layers corresponding to different pixel areas. Each light control layer contains specific illuminants (first illuminant in first layer, second illuminant in second layer, third illuminant in third layer) that convert light colors independently for each pixel area, preventing color mixing between adjacent pixels while maintaining color accuracy.
Solution Approach 2:
Different regions of the light control layer are given different local qualities by placing specific illuminants in specific locations. The first illuminant is placed in the first light control layer, the second illuminant in the second light control layer, and the third illuminant in the third light control layer, creating localized color conversion properties that prevent color mixing while improving color accuracy in each pixel area.
2Measurement precision
If multiple light control layers with different illuminants are used, then color accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple light control layers with different illuminants are merged into a single integrated structure. The first, second, and third light control layers are stacked together with spacers maintaining consistent distances between them, combining the color conversion functions of multiple illuminants into one unified light control assembly, thereby improving color accuracy while managing structural complexity.
Solution Approach 2:
Spacers are introduced as intermediary elements between the first, second, and third light control layers. These spacers maintain consistent separation distances between the layers, enabling the integration of multiple light control layers with different illuminants while managing the structural complexity through standardized spacing mechanisms.
3Illumination intensity
If light control layers are placed close to light emitting elements, then visibility is improved, but color mixing occurs between pixel areas
Solution Approach 1:
The solution transitions from a two-dimensional planar arrangement to a three-dimensional stacked structure. Multiple light control layers are arranged vertically above the light emitting elements with consistent spacing maintained by spacers. This vertical arrangement in another dimension allows the light control layers to be close enough to the light emitting elements for high visibility while preventing color mixing through spatial separation in the vertical dimension.
