NailDisplay – in the future we could use screens that do not allow fingers to cover touchscreens

One of the main problems of the touchscreens lies in the fact that our fingers covering the screen when you press a certain portion of it, and the problem could be solved quite easily in the future. If you look at the picture below, you will notice that OLED screens can be used to take pictures of touchscreen and display our fingers when we touch the screen. The image device was developed at a university in Taipei, Taiwan, and they believe that its main use would be for flexible screens.

NailDisplay is the name of the device which has a screen of 94 x 64 pixels and of course syncs with smartphone touchscreen which is used. The device can work both with touchscreen, and the devices that have screens, and although the proof is done by showing keystrokes on a keyboard, the same can be theoretically used in games or other applications. I do not know how such technology is useful for users, but in the future it could be used to display images from multiple devices, or to allow users to control software using their eyes only.
