LEDs... is there anything they can’t do? Well yes, actually, there is. They can’t be something other than a point light source. That’s not ideal when it comes to flat – and increasingly thin – displays such as television and cell phone screens. How does one go about converting that three-dimensional point light source into a two-dimensional display, without losing much of its intensity? The answer could be found in a new machine that efficiently and inexpensively produces fiber optic film sheets.
