Having skimmed the text of the patent claim, it appears to me that using an LCD monitor would be completely outside the scope of the patent:

The satellite facilities are sales and information terminals, each equipped with a CRT (Cathode Ray Tube) for receiving and displaying requested customer information from the computer's data sources at the data processing center.

So I guess all the web retailers have to do is add a disclaimer that only customers using LCDs or OLEDs are allowed to access the system!
