In addition to the use of OLEDs by Sony and LG's two mini-TVs, OLEDs have so far only been commonly used in mobile phone screens. But it is conceivable that OLED will definitely be used in tablet computers, digital cameras and super-table technology in the future, and will definitely be used in the field of large-screen TVs.
Are you waiting for an OLED TV? How is their price? What are the technical advantages of OLED? Next, let's elaborate on it.
What is the difference between OLED and LED?
There is a big difference between them. It sounds similar, but the process is completely different. OLED refers to an organic light-emitting diode, and "organic" refers to a carbon film between two conductors. The OLED display emits its own light when there is current passing through it; however, the cells in the LCD display are transmissive - they require an internal source to illuminate.
Until now, the problem of the lifetime of OLED displays has always been a question mark, but due to the high failure rate, the production line has been losing money. Obviously, change is imperative.
What are the advantages of OLED?
Gamers and home theater enthusiasts will love OLED. We have tried it ourselves to ensure that the display is lightning-fast. The speed is about 1000 times faster than LED-backlit LCD displays (and others say it will be faster) and better than plasma technology.
No blurring occurs, the display is clearer, and although it is a fast moving video, the light output can control each pixel, so the brightness control can be positioned.
How thin is the OLED TV?
The effect is good, dark black, fresh, pure white, and the accuracy of the color is also improved - all of them come from a shape factor, the thickness is only a few millimeters, much lighter than the standard TV. This thickness allows the sub-pixels to illuminate themselves, meaning that no bloated backlights are needed, which in turn means more energy efficient.
Which OLED TV will be available in the short term?
Last week, CES witnessed the world's first two large-screen OLED TVs in Las Vegas, and Samsung and LG's 55-inch will be available in the second half of 2012. The latest news reports that Samsung has announced that the company's "affordable affordable" 55-inch OLED TV will be available before Christmas 2012.
LG's OLED TV
The LG EM9600, which is 4mm thick and 7.5kg medium, is scheduled to enter the UK market in the second half of 2012. In addition to OLED displays, LG will introduce smart TVs with dual-core processors, WIFI, Freeview HD and Magic Remote.
Samsung's OLED TV
The product has a single window glass and is equipped with a wealth of audio control facilities. Samsung has to work hard to give its own model a model, which is indeed avoiding the essence of the problem: people's eyes are pulled back from the lab to Las Vegas, product plagiarism What information did LG publish? Probably. Samsung claims that the color reproduction of the company's OLED TVs is 40% higher than that of LED backlights. Although the thickness is only 7.5mm, it is twice as heavy as LG's "fat". Samsung's product is also available in the second half of 2012.
Are Samsung and LG's OLED TVs exactly the same?
different. Samsung uses "super OLED" technology, but LG is using OLED as a less noticeable "4-color pixel and color refiner." Compared to the traditional RGB color mix, LG's OLED adds a fourth pixel - white (somewhat like Sharp's Quattron TV), but still needs a color filter. Samsung claims that the company's super OLED technology does not require filters and is more advanced.
Can OLEDs implement 3D functions?
Both are 3D (Samsung uses active shutter technology, but LG plans to use passive camera 3D system), supports full HD resolution, although the effect is not so shocking, but they are not willing to combat the thickness of OLED products. Samsung's products are equipped with individually connected boxes containing power supply.
What is Sony's LED liquid crystal display technology?
There is no major news these days, and Korean producers are making major breakthroughs in technology, leaving Sony (the first manufacturer of OLED TVs in 2007) behind and slamming the commercial technology developed by Sony.
Unlike traditional LED backlights or edge LED arrays (around the light surrounding the screen), Sony's LCD LED technology (a model that emulates the 55-inch model at CES) promises to be cheaper.
Sony LCD LED TV
Sony technology is a single super-bright LED technology that is used in all sub-pixel full HD displays (all LEDs have 3 LEDs with a total pixel count of 6 million). The result is that the light source of the TV is actually in front of the pixel, but then the promotional effect will be similar to OLED--a faster and more colorful display with better playback contrast.
What is the price of OLED TVs?
Although both LG and Samsung are tight-lipped about the retail price of their recent favorite (we suspect, even they don't know it), the first OLED TVs are priced at twice the price of the best LED-backlit LCD TVs. Or triple.
For these specific brands, the LG 55-inch 55LW980T is priced at around £2,800, and the Samsung 55-inch 55D8000 is priced at around £2,000. This pushed the price of the first batch of OLED TVs to 4,000 to 6,000 pounds, and the lion opened its mouth!
Where is the future of OLED?
If LG and Samsung are forever deferred to the big-screen OLED TV, let alone sell it to ordinary consumers, please don't make a fuss. From a long-term perspective, the technical prospects for OLEDs are very good; there are already bendable and collapsible samples on the market that can be rolled up like paper; however, OLED screens will eventually be available – very thin, transparent and When it is not used, it will disappear until it is invisible to the naked eye. DisplaySearch analysts predict that OLED TVs will account for 2.5% of the 40-inch (or 40-inch or more) TV market by 2015 due to high prices and low marketed products.
