LED and OLED difference
Now the LED TV is the border of the LCD (liquid crystal display), it is distributed through the screen around a large number of light-emitting diodes from the independent wire to the center of the screen. It makes the screen thinner, but it also brings a disgusting visual angle problem.
In contrast, the OLED (organic light emitting display) screen is composed of organic materials that can emit light when there is current through. As a result of the removal of the backlight, OLED screen performance is more superior than other competing products.
OLED benefits
OLED televisions are able to provide higher density of pixels and sharper images, which means that OLED screens can display three-dimensional images without sacrificing images at the expense of most other televisions. In the OLED TV to enjoy the natural scenery when the video is like a window, rather than watch a glowing box.
Not talking about color yet. OLED display can artificially create all the natural colors. Read the LCD screen and then look at the OLED screen, it feels like "Wizard of Oz" in the first time Dorothy open the door to the wonderland.
OLED screen contrast is almost unlimited, so watch the Blu-ray disc "Dark Knight" when the screen does not appear color aliasing or black spots. OLED also overcome the problem of dynamic blur, usually in the LCD device will see when the characters quickly flashed on the screen when the annoying, terrible ghosts. These advantages alone are enough to make the OLED screen the preferred display for the game.
OLED screens not only make televisions lighter and thinner, but also free to bend. Has not seen any of this function of the big screen, but I believe that in the near future can be hanging from the ceiling of the TV.
What is the disadvantage?
OLED TV manufacturers have no quotes, you can imagine it will be about twice the price of LCD high-definition TV. Also, their usability is about ten years later you have to consider replacement, blue OLED only 14000 hours of life (equivalent to 8 hours a day can be used for 5 years).
Can not use this kind of TV in outdoor or light room, because too strong light will cover or dilute the TV image. Also, long-term exposure to ultraviolet light will be a substantial damage to organic elements, the formation of necrotic spots, resulting in regret the result is no longer worth the second-hand car.
You may have heard that OLED screens are less environmentally friendly environmentally friendly products, but that's not the case. The OLE screen consumes only 40% of the LCD when the image is black, but the power consumption of the OLD screen is normal when the image has a white background (Windows desktop, web page, TV drama burner MD) three times.
Has not yet become mainstream
We are different from the new OLED TV. Although it has achieved unrivaled picture quality, OLED TV has not been able to use. Even if the participation in the development of Sony in the technology is not mature before the only focus on the LCD LED screen.
If the family wants to share a TV as a daily watch, it will exclude these expensive categories. If there is a room dedicated to watching movies and TV shows, no more than 5 hours a day, OLED TV is worth considering.
