The approach that Sony is using is to use a blue laser (not separated R, G and B lasers) that illuminates a phosphor target which in turn emittes a white light. This is a much less expensive approach than using individual Red, Green and Blue lasers to individually illuminate the 3 display chips. In part the cost saving includes only a modest design change to the existing projector chassis. One forum member claims to have inside info that Sony will be bringing out a replacement for the VW1000es (4K UHD) model with a white light laser/phosphor source replacing the conventional lamp and may even offer a retrofit upgrade (for an unknown price) for the existing VW1000es projectors. We may hear more about this from Sony at the CEDIA Expo in September.
The new business-class VPL-FHZ55 is based off of the existing lamp-based VPL-FH36 model. It will be very interesting to find out what the price difference is between these two models as this may provide some indication of what the price difference will be for other upcoming Sony laser-based projectors (i.e.., using the same laser/phosphor white light approach) over similar conventional lamp-based models. The MSRP on the VPL-FH36 is $5850, but the sreet price is well under $5K.
