Virtual Boy
Gunpei Yokoi, Nintendo

“The standard way to create 3D images is by using liquid crystals. However, because liquid crystals require backlighting, even in complete darkness, a couple of percentage points of the light seeps out. [But the Virtual Boy’s LED display was not subject to this.] The idea was to have it be in total darkness, so you would not feel the frame of the screen.”
