Curved LCD Display Embeddable in Contact Lenses
The Centre of Microsystems Technology (CMST), Imec?s associated laboratory at Ghent University in Belgium, has developed a spherical curved LCD display that can be embedded in contact lenses. Unlike LED-based contact lens displays, the 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. The first prototype presented today contains a patterned dollar sign; 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.
