Abstract: Lenses, including contact lenses, and other transparent substrates include electronic circuits having patterned conductors and antenna structures which are transparent, flexible and conductive. A patterned conductor or antenna structure can be a combination of two-dimensional material such as graphene and one-dimensional material such as metal nanowires. The patterned conductor or antenna structure can be wrinkled or otherwise pre-stressed, to accommodate stretching and folding of the substrate. A biosensor having a sensor unit and an antenna unit, or other type of circuit, can be formed using these materials, and can be disposed on a contact lens.

Abstract: A display device is provided. A display panel includes pixels configured to display an image. An illumination sensor measures an illumination of ambient light of the display panel. A controller controls the display panel so that the luminance of the pixels decreases during a first time interval when the illumination of the ambient light decreases and controls the display panel so that the luminance of the pixels increases during a second time interval when the illumination of the ambient light increases. The first time interval is shorter than the second time interval.
