When you hear about a flexible touch display and a flexible display on a smartphone, it’s usually either a curved side of the screen, or just a gently curving phone like the LG G Flex. The really curvable and foldable devices are yet to be seen on the market, but today we have a new contender in the segment. Coming from R&D Core the DRAS Phone concept truly makes use of flexible technologies.
As you can see, the device is segmented and leaves a spot for the flexible to happen, leading to an accordion style mechanism. Below you can see a tablet/scroll version of the same DRAS concept. According to the designers, a truly flexible display will require a flexible touch sensor too. DRAS stands for “Digital Resistive Area Sensing”, that surpasses difficulties and limitations of capacitive touchscreens.
It offers improved spatial resolution and senses finger input force. The sensor can be scaled up for big screen TVs, laptops and big tablets. It can be placed behind a flexible display, without impacting its performance. The result is a truly flexible and rollable panel, with multitouch and finger force sensing, basically like Apple’s Force Touch.
Power usage would also be low. This is all conceptual and we have yet to learn how it all happens: organic materials, nano particles, glass or no glass and other things…
