LCD in a contact lens Scientists have built

Research Center at the University of Ghent in Belgium has developed a process for producing spherical LCD tiny size, which can be integrated into a contact lens and completely redo the form. Scientists' sample is a lens display, ability to display the dollar. This character can not burn or burn, any image can not be displayed. In addition, the wires connected to it that sends current to the liquid crystal matrix. Scientists believe that over time, based on the current design, they are able to create a completely self-contained unit. It is assumed that the first stage of such devices to be used for medical purposes, for example to protect a damaged retina or iris of the eyes from bright light, and in cosmetics - as a way of painting the eye in any color, in the case of the integration of the color LCD. Subsequently, the researchers plan to develop a display that can display any color image. Lens with such displays can cast the computer image on top of which the human eye sees, and will replace the glasses augmented reality, such as a untwisted now Google Glass. In addition, these lenses can be replaced sunglasses - and they will not need to shoot every time. It will be enough to disable the current and the lenses become transparent, or enable current to darken. Turn on or off the lens can light sensor.

But before that, developers have to overcome a number of difficulties, said project manager Jelly De Smet (Jelle De Smet). "If we talk about the flexible LCD screen, usually it is not a spherical displays. Create such a display was the biggest challenge for us, "- said the scientist. He added that the need to improve the quality of the display, so it can be safely applied on the eyeball. Despite many technological difficulties, the scientists believe that the first commercial lenses with built-in display can be on the market within a few years. "We have mastered the core technology. Now we can start working on the real version of "- researchers said.
