Sorry for the confusion Lynn. I was referring to your description of the
mechanical polarizer lens used to dim the display. Rotating one of the lens
to control the light attenuation is analogous to LCD displays, where the
"lens" (polarizers) are fixed, and the LCD material does the rotating.
The first part of your email covered the storage tube. I'm not too familiar
with how a storage tube works but there must be trapped charge in there
someplace, so I can see how the tiny capacitor analogy works for that.
