By Ankit Banerjee March 14, 2013 46 27 34 14 Samsung Galaxy S4 leaks and news are flooding in hours before the launch! We’ve already seen high-res image leaks of what the Samsung flagship is expected to look like, with the same person also uploading videos on some new Galaxy S4 features like the floating touch technology and Smart Pause. We now have some information, and maybe confirmation, of the type of display technology Samsung will be using for its flagship smartphone.Advertisement As US Patent and Trademark Office (USPTO) filing shows that Samsung has trademarked the term “Hyper Bright Display.” While this isn’t confirmation that the moniker will be used for the Galaxy S4, the rushed filing the past Monday seems to indicate that this might be the case. It certainly makes sense, with all the talk of PHOLED and ultra-bright AMOLED displays that have been reaching us for the past week. In case you’re wondering what this means, here’s a brief explanation. There are two types of OLEDs (organic light emitting diodes) in an AMOLED display, fluorescent and phosphorescent. For its previous devices, Samsung has used both types, with the green and blue OLEDs being fluorescent, and the red OLEDs being phosphorescent. The company is changing the combination this time around with the Galaxy S4, using phosphorescent for the red OLEDs as well as the green, with only the blue OLEDs being fluorescent. While we knew that this change is supposed to make the display more efficient and reduce power consumption, it looks like there may be a change in the brightness levels as well. This also puts into perspective the Galaxy S4 teasers the company has released, with the bright light shining from the box. With the design of the device looking to be somewhat similar to the Galaxy S3, maybe Samsung is banking on its upgraded display technology to woo consumers. We’ll be covering the launch live here at Android Authority, along with in-depth coverage of features, accessories, availability, and most importantly, comparisons.
