Contrast ratio review.
The all new LED technology is simply LCD with an LED backlight system. Backlights are used to illuminate the LCD screen. They do this from either the side of the display panel, or the back.
There are 2 ways that LED technology works, these are Array lit and Edge lit.
The array lit method.
LED lights are placed in the form of an array, which can be turned off as per the scene being played. For example, in a scene with a dark background, say the night sky, the LEDs present in that particular area can be turned off, explaining the saving of power and how dark these areas can potentially be.
The edge lit method.
In edge lit technologies, LEDs are placed in the sides, making the televisions a lot slimmer than your average LCD television. Compared to conventional LCD TVs, the pros of LED TV's outweigh the cons. They consume less power. The images are brighter and better with fresh colour tones, they have a long life and have very high contrast ratios.
LED technology is currently at the high end price range. The main reason behind this is because LED is brand new technology, it was the same when LCD and Plasma technology was introduced from the Tube and Rear Projection televisions. About 6 years ago when Plasma was first being bought into the UK a 42 inch basic 540p Plasma television screen would cost you about £4500 - £5000, within 3 years that price had dropped nearly half to about £2500-£3000.
Today you can purchase a higher grade 720p HD ready 42 inch Plasma television for roughly £800. Currently you can pick up a 40 inch LED television from a high street retailer for about £1200 - £1700 depending on what you want the television to do for you.
The new 8 series Samsung (Samsung UE40B8000) which has a mega high contrast of 5,000,000:1 Dynamic Contrast*,It is 200 hertz it has an Ethernet connection which allows connection to the internet,2 USB ports so you can connect USB devices such as a memory stick or an MP3 player so you can watch video's and listen to your music direct through your TV. The RRP is £1700.
The series 6 Samsung (Samsung UE40B600) which has a lower contrast of 2,000,000:1 Dynamic Contrast. It has a lower refresh rate of only 100 hertz. It doesn’t have an Ethernet port and only 1 USB port. The RRP is £1199.
If you own a laptop (which connects to the internet),don’t need to connect two USB devices and don’t want 200 hertz(most LCD televisions are only 50 hertz anyway).(please read contrasts at bottom of page for contrast reference).
If you agree with all of the above save yourself £500 pounds and go for the cheaper LED.
If I was going out to buy a TV today I would do one of two things, I would either go for a lower budget LED television or buy a top end LCD television. If you’ve got a HD device such as SKY+HD or Blu Ray I would definitely go for an LED.
I didn’t mention contrast above for three reasons.
Firstly because this is a dynamic contrast ratio, this is basically not the true contrast ratio of the television, this is the electronic contrast and not the contrast your eyes see.
Secondly, you could visit every single television designer/builder/distributor/company owner in the world and they will all tell you the same, there is no true way of measuring the contrast ratio of a television.
Lastly there is about 3% of the nation which can actually see the top end of the contrast ratio, Human eyes where not built for mega high contrast that most TV's these days can produce.
This is my review so any comments would be helpful.
