Type of LCD TV Panel Technology
Today LCD TV dominant display technology, compare to Plasma, CRT, and etc. For LCD (liquid crystal display), there are many different type of panel technologies used for production of LCD televisions and LCD monitors. LCD panel technology not limit by LED LCD TV or CCFL LCD TV, it is independent from the backlighting technology and it do contribute to contract ratio, brightness, switching speed (or respond time), viewing angle and color depth. The budget panel technology is TN panel, while the expensive panel technology target high-end market and professional quality are S-IPS and S-PVA panels. The average consumer usually has no idea what panel technology is used in their LCD TV, simply because the panel type is rarely listed by the manufacturer in the LCD TV specifications. Many buyers buy LCD TV based on price and size. Price should be a factor, but you should still know the advantages and disadvantages of the different LCD panel types and be able to identify them before you decide which LCD TV (model and brand) to purchase.

TV Technology Overview
Rear Projection TV
Rear-projection television
Rear-projection HDTVs still offer the biggest screen for your buck, although falling prices among big-screen plasmas – 58 inches and up – are forcing RPTV makers to cut prices on their own. It’s pretty obvious, in fact, that eventually RPTVs will go the way of the dodo as flat-panel HDTVs take over completely, but we’re still a couple years away from that. Rear-projection sets start at a sizeable 50 inches and go up from there. RPTV utilizes digital light projection or DLP technology that is driven by a lamp that bounces light through an assembly that produces color and then projects it onto the big screen. Upside for Rear-projection television is less-expensive at very large screen sizes than plasma or LCD TV, and able to produce good black-level performance on certain best models. The only downside is the lamp requires periodic replacement, thicker and bulkier than flat-panels, rainbow effects (on the projected light beam), less impressive off-angle performance than plasma and LCD televisions.
What Is “HD Ready”
Walk into Best Buy, you would see a lot of televisions put a sticker with label of “HD Ready” or “Full HD” on the corner of the television frame. What is the real meaning of “HD Ready” and what kind requirements the product need to meet to classify as “HD Ready”?
