They create LCD screens integrated into contact lenses for augmented reality

Researchers from Ghent University (Belgium) They have created a display with LCD technology, concave in shape and the size of a contact lens, which contains an LED screen with a significant number of pixels that allows it to display images.

A group from the Center for Microsystems Technology at Ghent University (Belgium) has developed a tiny LCD display, the size and shape of a contact lens, in which they can represent images (at the moment monochrome, and simple). The entire circular area of ​​the display can present information, and represents a great advance in terms of the use of LCD displays., because of its size, shape and physical properties.

Its creators affirm that this technology will have a series of very interesting uses in the field of health and cosmetics.. For example, could be used to control the amount of light that reaches the retina of people who have damaged irises, darkening in a certain way to perform said task. On the other hand, They could also be used in the future as personal lenses that can change eye color, as well as for taking measures for celiacs. Their construction is carried out with a very thin flexible spherical substrate., Inner U shape containing active layers and conductive polymers.
