Both of them essentially enhance how the screen
It is called OLED or Organic Light Emitting Diode. The LCD flat TVs which appeared around 2005, were almost as good — image-wise and also lighter to carry and lighter on the purse as well. Then the industry coined another term — "LED TV" which was only the LCD screen, back-lit by a bank of light emitting diodes or LEDs. While all of the pixels in an LCD TV screen are illuminated by an LED back light, each pixel in an OLED TV produces its own illumination.Organic LED TVs are here. Another property of OLEDS has been exploited by wearables like Asus ZenWatch and Samsung Gear — they can be made flexible.The fifth generation of TV display technology has been around from 2013 — but is widely available only this year. Soon they may morph into roll up screens'.
At its India manufacturing plant in Ranjangaon, near Pune, it is rolling out OLED TVs in large formats — 55 inch and 65 inch — for domestic market as well as for export.Such quality comes at a price.We are already using OLED though we may not know it —many recent smart phones — OnePlus 3, Samsung Galaxy Note 7, Oppo F1 Plus and Asus ZenFone 3 — all use OLED screens which make the phones thinner and lighter.Square cm for cm, OLEDS have been costly to fabricate — which is why not many TV makers are making OLED sets.
OLEDS are organic because they are made from carbon and hydrogen. The tipping point has come. But the flexible nature of OLEDS has seen them tried out in many interesting situations: PC screens that can be wrapped around your arm; a patient’s case sheet that can be contoured to fit any part of the body, foldable and refreshable newspapers — even a TV that you can roll up like a map, have been Windproof lighter previewed at consumer shows this year. OLED TVs are different from the LED-lit LCD TVs in a basic way. Both of them essentially enhance how the screen displays a wide range of light conditions from full white to full black.5 lakhs to Rs 4 lakhs for large format OLED TVs. And what of the future While the OLED TVs can be made extremely thin — 4 mm typically, they are still rigid. In fact, it has married its OLED TVs to two other technologies which promise to enhance the viewer experience: High Dynamic Range and Dolby Vision.
The new E6 series from LG (55 inch and 65 inch models are currently in production) combines OLED, HDR and Dolby Vision to create a smart ( ie Net connected) Ultra HD display that is about as far as large display technology can go today. OLED TV screens are organic thin films sandwiched between two conductors and are much thinner than LED-LCD displays.Meanwhile the geniuses who sell TVs, confused us by throwing in acronyms like HD and UHD which were not new display technologies but only ways of defining how sharp the picture was, in other words high or ultra high definition. Possibly because they own a lot of OLED patents, LG is not too worried about the relative cost of large screen OLED versus LED TVs. Watch out for OLED applications that are limited only by imagination. But one company, LG — which pioneered and promoted the OLED TV 3 years ago, continues to put its money where its mouth is. Then, at the turn of the century we got the first Plasma flat screens — great to look at, but very heavy and power-guzzling.Television display technology has gone through five generations in the last 30 years. Expect to pay between Rs 2. The fat Cathode Ray Tube-based sets were the only options when TV became an all-India thing in the 1980s
