Recently we have seen Nokia incorporating a technology known as ClearBlack in the screen of their devices. In fact, the new Nokia Lumia 800 and Nokia Lumia 710 came equipped with a famous panel of this kind . But what is it exactly? What is the reason why the Nokia team emphasizes so much this new technology? Well, actually is because the ClearkBlack screens offer a better experience on unfavorable light conditions, such as outdoors. If sunlight falls directly on the screen, it tends to produce a glare and finally you end up seeing nothing. Nokia explained the properties and performance of the ClearBlack technology using their Nokia Conversations grup, so that everybody is clear on what they will be buying when choosing a product from the Lumia family.
These displays are also known by the name of ultra-bright , since they include some additional nits. The nits are unist that measures the luminance. The word comes from Latin and in fact is used to define the brightness quality that screens have. In any case, Nokia Conversations tells us that the ClearBlack screens operate through a series of polarized layers that serve to eliminate any reflex produced by external light. Actually, this is a technology almost identical to the one used in traditional goggles to swimmers. If you have ever used a pair, you know that when you dive into the water the picture is completely clear. Thus, what Nokia has done really is to devise a system that processes ]light through many layers so when the image comes out “of it” it is completely clear.
Nokia ClearBlack Display - What Is It Exactly - How Does It Work
As you have seen in the chart that we have reproduced above, the light goes through the different layers and bounces in a perfectly designed way in order to have a partial blockage of the light that impinges directly on the panel. The result is a sharper picture, more realistic black color and a better viewing capability in open spaces, which until now could not be found in any lower-end device. The success of this technology has encouraged Nokia to use ClearBlack screens in many of their devices coming to market and not just those that run through the operating system Windows Phone and therefore are part of the Lumia family.
