Hi James:

What you have said may very well be true and is reasonable to me. The
papers that I have seen date back to 1999. At the time, the incremental
cost of the additional panel(s) may have been a significant economic
issue. LCDs are ubiquitous and prices have fallen thus eliminating the
cost benefit.

I was just curious to see if anyone build and sold any with two panel
scheme.

Thanks,

Derek
