Canadian
researchers have developed what they are claiming is the world's first
holographic flexible smartphone, with a bendable display that allows multiple
people looking at the device to see different 3D images depending on their
perspective. The smartphone sports a Full HD LED display with 1,920 x 1,080
resolution. When the device displays images, it renders them into 12-pixel wide
circular blocks. Over the top of the display is a thin 3D-printed microlens
array, consisting of over 16,000 fisheye lenses.
When the pixel
blocks are viewed through the lens array, it makes the images look 3D to the
viewer depending on their angle, when in fact they're actually only
two-dimensional. The one downside to this technique is it makes the appearance
of the display decidedly more pixellated. Once the Full HD resolution is effectively
down-sampled via the image-rendering process, you're left with a pretty
chunky-looking 160 x 104 resolution image.
