Breakthrough in Augmented Reality Contact Lens

The Centre of Microsystems Technology (CMST), imec’s associated laboratory at Ghent University (Belgium), has developed an innovative spherical curved LCD display, which can be embedded in contact lenses. Unlike LED-based contact lens displays, which are limited to a few small pixels, the new LCD-based technology permits the use of the entire display surface. By adapting the patterning process of the conductive layer, this technology enables applications with a broad range of pixel number and sizes, such as a one pixel, fully covered contact lens acting as adaptable sunglasses, or a highly pixelated contact lens display.

 

The first prototype contains a patterned dollar sign, depicting the many cartoons that feature people or figures with dollars in their eyes. It can only display rudimentary patterns, similar to an electronic pocket calculator. In the future, the researchers envision fully autonomous electronic contact lenses embedded with this display. These next-generation solutions could be used for medical purposes, for example to control the light transmission toward the retina in case of a damaged iris, or for cosmetic purposes such as an iris with a tunable color. In the future, the display could also function as a head-up display, superimposing an image onto the user’s normal view. However, there are still hurdles to overcome for broader consumer and civilian implementation.
