LED TV – Don’t Be Fooled, Understand The Technology First.
Thinking of buying an LED TV, well….Stop! Before you spend in excess of $1500, you need to cut through the jargon and hype to truly understand the technology that you’re actually spending your hard earned money on.
TV manufacturers and the media are very good at convincing us that the latest products incorporate the most cutting edge technology and are a must have. Lets get real here, to the average consumer most of this jargon is just down right confusing.
A new range of LED TVs that have hit the market with a big buzz. Samsung have crept through the backdoor and have released the 7000 series range boasting LED technology.
Thats great…but what is this LED technology thats being boasted.
Current LED TVs – The Truth
The term ‘LED’ stands for Light Emitting Diode and as you may well know LEDs are used in many of our devices at present, however in terms of the current line of LED TVs, the actual LEDs are used for the backlight of the TV ONLY and not the tv display themselves. If you consider that current TV technology uses CCFL (Cold Cathode Fluorecent Lamps), there ia no doubt that an LED backlight is a more efficient form of backlight.
However, the important point here is that the LED television’s display is actually LCD (Liquid Crystal Display), it is the backlight only that is made up of LEDs. So there are two major technologies at use here; LCD for the display and LED for the backlight. In essence a more advanced form of LCD TV.
When you compare this technology to a true LED display TV. Displays such as OLED (Organic Light Emitting Diode) will self illuminate, utilizing an internal thin layer of LED for its display only.
The fact that the ‘LED tv’ term has been used to describe a type of LCD TV is a cunning move on Samsungs part, but genius in terms of marketing, since it capitalises on the current buzz in the TV market of true LED display TVs such as Sony’s XEL-1 OLED TV.
LCD TVs with LED Backlights – The Improvements
Now that we’ve established that this is LCD TV with an LED backlight, lets look at how this new range of tv improves on current TV technology such as plasma and standard LCD in 3 key areas:
1. Picture Quality
Quite simply, the picture quality has been improved over standard LCD and Plasma, because the range of colours have increased. The utilization of Light Emitting Diodes as a light source instead of traditional lamps provides a higher contrast ratio because the LED produces blacker blacks and whiter whites, this is the key to achieving quality images on screen.
