Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional light emitting displays are used, then the device can display color images, but the color reproduction ratio is poor due to broad light spectra
Solution Approach 1:
The patent changes the spectral parameters by introducing inorganic particles (Nd2(Si, Ti, Ge)2O7) that modify the light spectrum emitted by the light emitting element. These particles narrow the full width at half maximum of the light spectrum, transforming the broad spectrum into a narrower, more defined spectrum that improves color reproduction ratio while maintaining the display function.
Solution Approach 2:
The patent uses composite materials by combining inorganic particles (Nd2(Si, Ti, Ge)2O7) with the light emitting element and color conversion layer. This composite structure allows the inorganic particles to interact with the emitted light and narrow the spectrum, achieving improved color reproduction without requiring complete redesign of the display device.
