LED TV Update

Filed Under LED TV, LG LED TV, Philips LED TV | Leave a Comment

The LED TV market is hotting up with recent announcements from LG and Philips to add to the Samsung LED TV hype.

It’s not clear to me if the vendors yet agree on what constitutes an “LED TV”. Each has their own spin to suit their products’ strengths and orientation.

Some vendors e.g. Philips and LG use LEDs for backlighting, whereas others use it as the primary illumination.

Philips say their Ambilight 42PFL9803H/10 42 inch LCD / LED TV features:

LED Lux Display
MPEG4 HDTV* and the Perfect Pixel HD Engine
Perfect Motion, Perfect Colours and Perfect Contrast with Ambilight Spectra 2

This LCD TV has multi-array LED backlighting and uses multiple LED arrays each controlled individually, in contrast to regular LCD screens that only have one backlight to illuminate the entire screen.

Note: This is different LED technology to Samsung LED TVs where the fundamental illumination of the TV is done via LEDs, not just the backlighting. You could describe this as “half-way house” LED TV technology

However, the Philips LED TVs generally get excellent reviews, although the retail price is higher (up to twice as much) than a comparable Samsung LED TV.

LG LED TVs

LG’s LH90 LED TVs have been announced and priced (42 inch model retails at approx $2,400) but the availability isn’t clear yet - possibly next month (June 09).

The LG TV specs include:

2,000,000 : 1 MEGA Contrast Ratio
1080p Full HD Resolution - TruMotion 240Hz
LED back light Technology
24p Real Cinema
Picture Wizard : Easy Self Calibration
Smart Energy Saving Plus

Samsung LED TVs

Samsung LED TVs use LEDs as their primary light source, instead of traditional cold cathode fluorescent lamps.

Samsung say this allows their LED TVs to achieve higher contrast ratios, thinner TVs and 40% energy saving compared with LCD TVs of the same size.

Viewing tests indicate LEDs produce darker blacks and crisp whites, with vivid colors, resulting in improved picture quality. Samsung have also added their Auto Motion Plus frame interpolation technology that reduces motion blur and image judder.

On the minus side, it seems that the average life span of an LED TV is 40,000 hours, which is down on an LCD TV which averages 60,000 viewing hours.

If you watch TV 4 hours a day, 40,000 hours = 13.7 years and 8 hours a day viewin gtime = 6.85 years.

The Samsung LED TV models were introduced in 46-inch (priced at P260,000) and 40-inch (P160,000) variants last month while the B7000 55-inch model will be launched this May.

Samsung LED TV

So putting the usual hype aside for a moment, what is LED TV exactly and what benefits does it offer?

The latest Samsung LED TVs, such as the UN46B7000, use an edge-lit LED-based, TFT active matrix, LCD panel (what a mouthful of techno-jargon!). Basically this means that the TV uses LED Backlight technology to increase the amount of light passing through the LCD panel.

So far Samsung is the only company to announce a full lineup of LED-based LCD TVs. These are still expensive as new technology products usually are, before the production volumes crank up.

However, if you’re desperate to impress your neighbours today, LED TVs offer the most advanced technology (at least until OLED comes along) and their design looks as sexy as hell, not least because they’re super thin.

Samsung also claim a 40% reduction in the power consumption for the LED TV compared with previous model, same size TVs.

Features:

The LCD TV panel is only 1.2 inches thick and the 46 inch model weighs around 50lbs (light for its size) and Samsung claims it is very easy to hang on a wall as a result.

For comparison a previous Samsung LN46A950 LED-backlit TV, which was released in 2008, weighs around 68lbs for the same screen size.

3,000,000:1 Mega Contrast ratio provides an extended brightness range - deep blacks and bright whites.
Advanced Color Processing for a wider range of natural colors and greater picture depth.
Auto Motion Plus 120 Hz technology eliminates virtually all motion blur, for a smooth and crisp picture.

Street Price at time of posting:

The Samsung UN46B7000 has a screen size of 46 inches and a price of around $2,500 (April 2009).

Reviews and User Feedback

CNet said:

“. . [there are] some picture quality trade-offs caused by the LED system, namely less-than-perfect uniformity and off-angle viewing, along with the backlights’ somewhat distracting fluctuations.”
