Who is going to be the first to cut one apart so we can figure out how the JVC color sutter works?
Some questions:

1. 2 or 3 liquid crystal cells in the assembly?
2. RGB or MYC colored filters/cells?
3. External polarized color filters on the liquid crystal cells, or some sort of "colored magic liquid crystal goo" fill in the cells?

Question 1. 3
Question 2. External based on the below comment, however JVC says there are two? polarizers and two shutters? Uncertain here.

From JVC press release: "single electron gun aimed through red light, green light and blue light filters, each separated by a liquid crystal shutter."

Jerome's illustrations were from a JVC brochure.

If you read through the Hughes/JVC Patent, it talks about your other question. It appears that JVC made some enhancements by adding a second polarizer.
