5. OLED is an immature technologyWhile this is hardly the first generation of OLED displays in general, it's still a fledgling compared with mature LCD and plasma technologies. Two problems facing mainstream OLED production are the relative lifespan of the "blue" pixel, and a relatively low yield. Compared to the red and green pixels, the blue pixel is much less efficient -- with studies saying it is as low as 4 percent while the other two are as high as 20 percent, according to Digital Trends. The blue pixel may also reduce your display's life with older research of the Sony XEL-1 suggesting after only 1,000 hours of use the display had dimmed by 12 percent. It's probable that the technology has improved since but no company is quoting any numbers.

Low yield refers to the fact that for every OLED TV that manages to make it onto store shelves, a relatively iphone screen protectors bulk high number of panels have to be scrapped as defective, According to DisplaySearch as of December 2012 yields were as low as 10 percent, However Samsung, for its part, claims a recent, unspecified improvement in yield is the reason it dropped the price of its first OLED by $6000, By no means does this indicate the yield problem is "solved" because until it is, OLED will remain a niche product..

Neither company has published an official lifespan for its new OLED TVs. However, both the LG and Samsung OLED sets come with a 12 month warranty. 6. They're not 4KGiven that OLED televisions cost a lot of money, you might be surprised to find they don't support 4K/Ultra High Definition. Sony and Panasonic both showed off 4K OLEDs at CES 2013 and demonstrated that it's possible to produce these displays in a 55-inch size. While it's yet to be seen what impact 4K will have on the market, high-end buyers looking at OLED might be rightly holding back because they want 4K, too. As we keep saying, however, OLED isn't easy to make. Therefore it isn't safe to assume that just because the cost gap between 4K and 1080p in LED LCD TVs is narrowing, the same will happen with OLED.

In the meantime, high-end buyer, take heart that at the 55-inch size of today's OLED TVs, the benefits of 4K resolution are likely to be nearly invisible, 7, There are competing OLED technologiesNothing like a good old-fashioned "format war" to keep the consumers on their toes, eh? Samsung and LG have fundamentally different approaches when it comes to pixels that iphone screen protectors bulk make up these displays, and it's still too early to tell which will be "better" in the long run, Samsung's method incorporates discrete red, green and blue subpixels into its display, just like a plasma or LED LCD, Given the uncertainty surrounding the blue pixel, it's uncertain what the long-term reliability will be..

LG's way around the "blue" problem is also potentially more cost-effective. It uses a grid made up of white OLEDs (which is actually compressed layers of red, green and blue OLEDs). Over these the company overlays a series of color filters to produce four different subpixels: red, green, blue and white. The advantage, LG says, is that the panel can produce a much higher brightness, which could give it the edge in a brightly lit environment over Samsung's method. We haven't seen LG's OLED TV in person yet, nor compared it directly to Samsung's, so we won't speculate which one's "better" from a picture-quality standpoint. It may be years before we know which one wins in terms of reliability or longevity, let alone market popularity.
