The already booming market for large LIQUID CRYSTAL display televisions (LCD TVs) is set to grow even more than previously expected in the coming year, according to analysts at market research firm iSupply Corp.
The firm now predicts 75.2 million LCD TV panels will be shipped in 2007, up 42.7% from 52.7 million in 2006. The firm has upped by 3% it's previous forecast issued in December of 72.9 million LCD TV panel shipments in 2007.
Even though growth is strong, the market is nevertheless starting a slowdown of sorts.
In 2006, shipments rose by a whooping 95.8% to reach 52.7 million units.

"This strong growth in 2007 will pave the way for LCD TV panel shipments to exceed 100 million units in 2008 and then grow to 171.6 million units by 2011," Sweta Dash, director of LCD and projection research at iSupply, said in a statement.
"By that time, LCD TVs will dominate the market accounting for 65% of all television unit shipments worldwide."

The booming shipments may have a lot to do with the increasing affordability of large screen LCD TVs. Prices for large-sized LCD panels used for televisions are declining "precipitously" in 2007, iSupply said.
For example, the price of a 32 inch LCD TV panel is expected to fall by 17% in the first half of 2007 compared to Q4 2006-- strongly increasing the consumer adoption rate for 40 inch and larger LCD TVs.
Othe factors contributing to the accelerated shift to larger-sized LCD TVs include the switchover to high-definition television (HDTV) and the increasing adoption of wide-screen formats sets.

Frequently Asked Questions:

PLASMA or LCD?

Beauty is in the eye of the beholder. Personally, the cost of LCD is better than Plasma.
Technically, LCD display lighting is simpler being panel backlighting, thus less power supply demands. Response time (picture persistence) is better with Plasma.
Look at the screen from around 1 metre. Chose a screen that is the size required with the least amount of individual picture elements visible - smaller pixel size or higher number of pixels for a particular screen size.
View and view again the various types.

If in doubt, wait! OLED is around the corner along with another LASER system.

Is it the picture tube?

Excess picture tube wear can be diagnosed by the customer.
Before failure how was the colour?
Was there a dominant hue? If not then the chances of a worn out tube are very low.

Is the TELE worth repairing?

The main criteria is the picture TUBE. Provided the tube is OK ....more than
likely, yes. A good CRT (cathode ray tube) supplies very fast response times along
with superior contrast and may last for 5-10 years allowing time for the
alternatives to be developed further or newer better technologies to be completed.

How can TUBE usefulness be determined?

What is the best brand to buy?

Electronic circuitry is generally similar throughout the various makes and models.
Thus reliability is usually the same. The main difference is features, ie: teletext/stereo/flat screen.
Spare parts can be an issue, best to stay with well know brands.

Alternative TV solution?

PLASMA screens, LCD, REAR PROJECTION and PROJECTORS are fast replacing the
conventional picture TUBE. For the actual screen size PLASMA is still too costly,
REAR PROJECTION has good size but such a big box, whilst PROJECTORS can
provide a HUGE screen with a discrete ceiling mounted box. There are pros and
cons for each system. When considering screen size, cost, and bulkiness
overall a PROJECTOR is in front, in our opinion.

There is a catch: Manufacturers print disclaimers regarding dead pixels.
A screen element can either blackout or whiteout, although each element is
small a faulty pixel is most annoying. REAR PROJECTION is immune!
