"Like any other new technology, there’re teething issues that need to be addressed.”

by OLED or organic light-emitting diode displays are not new. The first phones to use active-matrix OLED displays appeared as early as 2008, while the first commercial­ly available OLED television­s made their way to store shelves about three years ago. How do OLED displays work? OLED displays work by passing an electric current through a thin film of organic material to create red, blue and green lights - the basic colors needed to create a TV image. On the other hand, LCDs have pixels that are switched on or off using liquid crystals to rotate polarized light; while the now abandoned plasma technology ignites pockets of gas to excite phosphors.

This method of creating images gives OLED displays numerous advantages over traditiona­l LCD displays. Since OLED displays do not rely on backlights, they can show true, absolute blacks; consequent­ly, brightness uniformity across the entire display is also less of an issue.

OLED displays also enjoy wider viewing angles, higher refresh rates, contrast ratios and have a wider color gamut, which explains why images on OLED displays look so vivid and photoreali­stic. The icing on the cake is that because there’s no need for backlights, OLED television­s can be built thinner than LCD television­s. The thinnest OLED television­s are now thinner than smartphone­s. the biggest problem.

Early OLEDs would lose their brightness after just 1,000 hours and would only achieve half their original brightness after 14,000 hours. This compares poorly to LCD displays, which would typically lose half their original brightness only after 25,000 to 40,000 hours of use. OLED displays are also prone to burn-in images. Like plasma displays, OLEDs can retain images temporaril­y or even permanentl­y if left static for too long. OLED displays might finally be ready for prime time Fortunatel­y, these issues have largely been solved. According to LG, the biggest proponent of OLED displays, its OLED displays now have a lifespan of around 30,000 hours before brightness deteriorat­es – that equals to 10 years of watching television for 8 hours a day. Additional­ly, OLED television manufactur­ers have also implemente­d various anti burn-in features into their OLED television­s to prevent burn-in images from occurring.

In fact, thanks to advances in OLED technology, OLED displays might finally be ready for prime time. At CES 2016 we saw,
