Re: Microelectromechanical mirrors (MEMS) are NOT SOLID-STATE...according to Wikipedia
Apples and oranges.
An LCD TV backlit with LED is an LED TV. The backlighting prior to LED was florescent tubes. LED distinguished the two. When OLED came to market, that is where the confusion came in and they distinguished the backlit as LED LCD (LCD being the underlying tech.)
Solid state is no moving parts, not just at the macro level
"If people want to call it "SS performance and reliability", that is fine."
That is not what they are calling it but rather an admission to the fact that it is not solid state but they believe they have attained the same level of reliability and performance of the holy grail solid state type design category.
