OLED Technology Casts A Spell On Big Screen TV

5/28/2012 5:19:36 PM

You must have waited for years with the hope of a big OLED TV existence; afterwards, there wasn’t one but two TVs showed up simutaneously, with the fact that both Samsung and LG introduced 55” OLED TV in CES 2012, Las Vegas.

It is an extremely exciting moment because technology has been mature in the end while long time ago, the one and only OLED TV model was on the market was 11” model of Sony. The huge benefits of OLED made it become an interesting development. Instead of using backlight as LCD TV, each pixel is self-illuminating whenever the electric current runs through.

In conclusion, this means the deep dark and impressive contrast. LG said its TV has the contrast ratio (the difference between the darkest and lightest colours created on the screen) more than 100.000.000:1 in comparison with that of the incredible plasma TV currently of Panasonic is 5.000.000:1.

The competition between these two companies is extremely tough. LG led in the thickness aspect with 3mm thick TV while a model of Samsung is twice times thicker than that with approximately 6mm.

Samsung stated its Super OLED TV used a better technology with professional RGB pixels to create more shade of colours in comparison with LG, who used white OLED light and RGB filter to create colours.

Setting the technical specifications aside, both TV made us shattered whenever they caught your attention. The black is pure while the white is so bright. The colour reproduction on these two models is unbelievable, with incredible amazing viewing angle, have no colour downgrade even when standing to its side.

Furthermore, these two companies also demonstrated their technologies by using glare-testing scenes which had black background and light colours mix together. OLED could solve them confidently. In reality, the one and only problem of OLED is it which made other TVs looks inferior in comparison.

Both of these TVs are 3D. LG also demonstrated TV with the passive system, but Samsung was the one proposed the active 3D glasses, which would work well because OLED is so quick that there will be no chances for cross-talk, when an eye catches the image of another eye.

However, there are still questions about the technology and these models. One of the hottest problems is its life expectancy. A typical OLED screen has the blue pixels reduce half of the brightness fastest with 14 thousand hours (5 years with 8 hour a day). The RGB filter of LG can avoid against this issue but we don’t have the faintest idea about how Samsung could deal with it. One strategy used in other companies is enhancing the blue when the TV is new to make its images bold, which would to fade into its normal state with time. Though, traditionally, OLED life is not as long as plasma TV or LCD, which will decrease its brightness after 25,000 to 40.000 hours.

Then, availability and price will come into consideration. Both companies have the intentions of introducing these models next year, but the exact time wasn’t released. As for the price, OELD is still an expensive technology in the infancy stage, especially with the big size. According to our information, a LG TV may set back at $8000 (approximately £5200) and TV of Samsung definitely cost you the same amount of money.

Yet price and its availability are not the main problems to these TVs. That proves that OLED technology can be made in whatever necessary size. These models are a great development in an incredible technology which can bring the quality of CRT along with benefits of a flat screen.
