there are two types of rear projection tvs eh. the most recent ones are the DLP type, which utilizes a texas instrument chip. pero sa US 2 brands lang ata meron ang DLP, samsung and RCA. pero more brands will jump on this trend. it is way better in terms of picture quality kaysa sa mga old rear projector types. as of the current models, it still can't match a plasma tv na hdtv. (may plasma na edtv lang kasi). but texas is rolling out a new set of chips that promises to equal that of plasma's picture quality.
LCD naman, better siya for still images compared to plasma since less chance ng burn in. meron daw isang kaso sa states wherein a guy watched ESPN for a couple of hours and the logo on the upper right hand side got burned in. newer plasmas don't get burned out as much as the old ones though so be carefull if you're buying one. pero LCD pinakamahal sa kanilang lhat. but many are expecting its price to drop considerably. sa PC monitors nya 15K ata for a 15inch. so roughly 1K per inch. in 3 years time daw baka it'll be as cheap as that, making it even cheaper than the DLP projectors. considering that it's lighter than plasma, and wala gaanong buzzing sound ng fan if you listen closely, it might challenge plasma in years to come.
plasma is plasma. the mac daddy of them all as of now. nagdrop na talaga prices nila. advantage ng plasma is that it has a high contrast ratio, even reaching 3000:1 for pioneer models. saka ok talga picture quality. downside is may tendency mag burn in and expected life niya is around 25,000-30,000 viewing hours. which will translate about 10 years if you watch an average of 5 hours daily. pero pag about daw ng mga 5 years, it has already used up half the gases and the picture quality will suffer daw especially the brightness. that's the major disadvantage of a plasma- limited life.
ako belib talaga ako sa samsung. they positioned themselves in all 3 of these HDTV capable TVs. the only company to do that i think. panasonic is coming up with DLP but not sure with LCD.
