      What you should know about flexible mobile displays. Samsung, LG, and others have been showing off flexible displays and even a  prototype phone  for years, but it's only now that bendy screens are going commercial. Samsung's Galaxy Round  and  LG's G Flex  raise a lot of questions about what a flexible display is and isn't, what the word really means, and just what kinds of benefits a bendable display would bring to a smartphone or any other gadget. What is a flexible display anyway? Colloquially, "display" means the thing you see when you look at your phone and navigate around. But more technically, display refers to the electronic material that sits beneath the glass or plastic cover (the part you actually touch) and is responsible for lighting up your phone. So when Samsung and LG (or anyone) talk about a flexible display, they're talking about the organic light-emitting diode, or OLED, layer -- located beneath the cover glass -- that's now m

New LiFi technology 100 times faster than the currently available Wi-Fi What is Li-Fi ? Light Fidelity or  Li-Fi   is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. Li-Fi uses common household LED (light emitting diodes) lightbulbs to enable data transfer, boasting speeds of up to 224 gigabits per second. Subsequently, in 2017 after four years of research, Haas set up company pure LiFi with the aim 'to be the world leader in Visible Light Communications technology'. How it works Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves while Li-Fi runs on visible light. As we now know, Li-Fi is a Visible Light Communications (VLC) system. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into 'stream-able' content. An LED lightbulb is a semi-conductor light source meaning that the cons

Mobile Radiation, Health Effects. Recent Researches on Mobile Phones Effects... Why is there concern that cell phones may cause cancer or other health problems? There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems: Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy. The number of cell phone users has increased rapidly. As of December 2014, there were more than 327.5 million cell phone subscribers in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion. Over time, the number of cell phone calls per day, the len
