Electrically focus-tuneable ultrathin lens for high-resolution square subpixels

In accordance to rising demand of high-resolution, ultrathin lens device for display panels, the scientists from Korea, UK, and USA have invented an electrically focus-tunable, graphene-based ultrathin subpixel square lens device that demonstrates excellent focusing performance. Such subpixel design is uniquely developed to control the optical path of subpixels of display in visible wavelength, which is therefore easily applicable to high-resolution slim displays as an add-on feature. Ultimately, this presents new directionality to autostereoscopic display.
