Final answer:
A frequency-separated display follows the principle of neither the principle of the moving part nor the principle of pictorial realism.
Step-by-step explanation:
A frequency-separated display follows the principle of neither the principle of the moving part nor the principle of pictorial realism. This means that the display does not rely on any moving parts or attempt to create a realistic picture. It is not a hybrid display that combines different types of technology, nor is it a type of tethered display. Instead, it is a display that operates based on frequency separation.
