Because it is absolutely wasteful to manufacture very huge sized LCD panels. The new 8th generation factories of top class makers are able to produce 40V-52V LCDs at lower costs now because of higher yield. 65V should follow the same trend soon.
Because at the moment, 65V is the biggest commercially available LCD size. Anything bigger is still beyond marketable price. Makers like Sharp are still scratching their heads trying to figure out how to cut manufacturing costs for something as big as 65V. So when you buy a 65V, you're also shouldering a good chunk of developmental costs.
Because it is a Sharp, the undisputed No. 1 LCD maker in Japan with more than 50% share of the very high-end Japanese market.
Because almost all components of Sharp are still made in Japan, ESPECIALLY the panel itself.
Because the bigger the LCD panel, the greater the challenge to actually implement an engine and all relevant circuitries that would optimize the overall picture quality.
Because it is a Sharp and it sells like hot-cake no matter how expensive, they are trying to maintain the premium on the brand itself. Any tourist coming to Tokyo for the first time might be very surprised to find out that in the land of LCDs and Plasmas, there are no 32" LCD sets selling for less than $1,200, while in the US, 32" LCDs can be had for like $600-900?
As long as the Chinese are not able to "copy" 65Vs, prices will remain high. The Chinese are getting there I suppose.
BTW, I didn't know that 65V costs 1.3M pesos. Certainly, that price tag includes shipping, importation duties and taxes, warranty services and mark-up of local stores. It is also priced at about 1M in Japan, but that is in Yen.
You can also think of it this way. Not all LCD makers have the capability to produce 65V so it quite a prestige to be able to actually have one in their product line-up. Correct me if I am wrong, but I think I have not even seen a Sony Bravia LCD bigger than 52V (70 inch Projection TV is another matter and a cheaper and easier technology). Sharp offered the 65V para ipangtapat sa 65V plasma of Panasonic. It is more expensive than Plasma and that is not surprising at all. So essentially, pangyabang lang ng Sharp ang 65V..he he he. For those who can afford a 65V plasma, puedeng-puede talaga nilang i-pangyabang..he he he
Final point, the Panasonic 103 inch plasma is tagged at 5.6M yen. At that price, you can buy 5 sets of 65Vs..he he he. The thing with display size, the proportions are like that of paper. For instance, sellers are saying that from 32V to 46V, you are getting nearly twice as big a picture. I've tested this personally and it appears to be true. From 32V to 42V is like 1.5x. Therefore, from 32V to 65V is like what??? 4x??? What about 65V to 103?? The rest is algebra.
