Mobile phones have come a long way since the days of monochrome screens and T9 texting, but where are they going next?
Flexible phone screens
Maybe the best-known innovation coming our way is the idea of a flexible display – one you can roll up and put in your pocket! Samsung has long led the mobile display pack with its organic light-emitting diode (OLED) screens features on the Galaxy line of phones, but LG just announced they’re taking up arms in the battle and committing $1.75 billion to boost capacity for these flexible OLED displays. OLED screens are expected to replace liquid crystal displays (LCD) for smartphones as the new standard in the next few years, according to Reuters, and their flexible displays can be curved or folded!
Holographic phone displays
RED, the company that makes professional digital cameras for shooting Hollywood movies, is making a “holographic” phone, powered by Android, called the Hydrogen One. The company’s press release claims the phone will have a 5.7-inch holographic display featuring “nanotechnology” to seamlessly switch between traditional 2D content, stereo 3D content and 4-view “holographic” display modes. There is a roughly $1600 price tag to preorder the titanium model phone which is expected to be released Q1 2018.
It’s not a touch screen, it’s a feel screen! Electrovibration technology, or TeslaTouch, will change the mobile touchscreen experience dramatically. You will be able to feel different kinds of texture! Imagine shopping for clothes online without worrying about the texture and quality of the cloth. Disney researchers have been working intensively on developing touchscreens that let you feel texture. It works on the idea that, through electrostatic charges, your brain is tricked into feeling texture simply by touching the device’s screen. As the user swipes, taps, and manipulates objects on a touchscreen, the software can generate tangible effects that mimic the bumps, ridges and textures of the surfaces of different objects. This could make interactive textbooks more engaging on tablets, allowing students to explore the 3D features of an object directly on each page and upgrading the standards of education, as we know it.
