There are no pictures here for obvious reasons. I've made a 20 inch display that passes electric current at 5 to 10 volts over a grid with spacing of 2 millimeters. You can touch the display and feel the underlying imaging through your fingertips. A shortcircuit with a little iron platter passes the position of touch (a diode controls direction) so the blind user can click items or read the underlying text. It passes regular HDMI and an emulated absolutely positioned USB mouse.

Contact me at to order one. I hope I will help you out. Total cost is 300 dollar at current production capacity.

Kind regards,
Kaj Toet
