The time of super high-resolution displays has already come with pixel densities of over 440ppi on most high-end Smartphone’s today. However, as the technology advances we might soon see even sharper screens arrive. So, Qualcomm demonstrates one of its future technologies. The company reveals its Mirasol front-lit power efficient 5.1-inch 2560 x 1440 pixel screen with a density of the whopping 577dpi. The Mirasol technology differs a lot from the current crop of LCD/OLED displays. It actually reflects light that falls on it in a way that is close to what we see in nature. However, the display does not have the same vibrant colors as on modern displays. It is colorful and not black & white like most e-ink.  Also, it is nearly 6 times more power efficient.

Apart from sharpness, being close to the way we see things in nature and not tiring the eyes so much is of its huge benefits. However, Qualcomm is still a couple of years away from bringing it to mass market which is a bad news. But the company is already showing early prototypes of the screen in a smart watch and a handset.

The NVIDIA Tegra 4i has been considered as a cheaper, smaller, and more power-efficient version of NVIDIA's current top-of-the-line offering of the Tegra 4. But the 4i is already getting an upgrade to support LTE-Advanced without changing the hardware at all. Also, it may get VoLTE support soon. NVIDIA is using a "software-defined modem" in the Tegra 4i, so these features can be added afterwards with simple software updates. Hence, instead of just supporting the current 100Mbps LTE, it is now also capable of handling 150Mbps LTE-Advanced service that is expected to start releasing by the end of the year. 

As per NVIDIA, it is also working on an update to add VoLTE to the 4i, which is also expected to start rolling out on Verizon and AT&T by the end of the year. A "software-defined modem" seems pretty amazing.

A new invention by 18-year-old Indian-American girl would amaze you completely. She has invented a super-capacitor device that could potentially charge your cellphone in less than 20 seconds. Eesha Khare, from Saratoga, California, was given the honor of the young scientist award by the Intel Foundation after developing the tiny device that fits inside mobile phone batteries that could allow people to charge within 20-30 seconds. As per reports by NBC News, the so-called super-capacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time. The young scientist has been awarded USD 50,000 for developing the tiny device. She has also attracted the attention of tech giant Google for her potentially revolutionary invention.

As per Khare, her device can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries. When asked about what inspired her to work on the energy-storage technology, she said, “My cellphone battery always dies."  Also, super-capacitors allowed her to focus on her interest in nanochemistry . As per reports, the gadget has so far only been tested on an LED light. However, the good news is that it has a good chance of working successfully in other devices, like mobile phones. According to Khare, “"It is also flexible, so it can be used in rollup displays and clothing and fabric. It has a lot of different applications and advantages over batteries in that sense."

The Jolla Smartphone is now official and it's simply called Jolla. The device is running the company's Meego-based Sailfish OS, which is now officially confirmed to support Android apps.

Jolla's specs are not completely revealed at this point. The phone packs a 4.5" display at the front and 8MP snapper at the back. There is 16GB of built-in storage, and user can expand that through the on-board microSD card slot. The battery is user replaceable, which lets half of the phone to snap out of the other half and as a result giving access to the battery. This Smartphone is available in these colors - light blue, green, white and orange.  Users will be able to interchange their back covers. After that, Jolla's Sailfish OS will identify which color is on and will adapt the theme of the UI to the color.
