according to the actual report http://pubs.acs.org/doi/abs/10.1021/nl302015v Two-dimensional (2D) materials, such as molybdenum disulfide (MoS2), have been shown to exhibit excellent electrical and optical properties.

While I have no specialization in the area, I gather that the scientist are suggesting it may be useful as a sort of screen technology, from the article

"For example, MoS2 could be applied to glass, producing displays built into a pair of eyeglasses or the window of a house or office."

Very exciting stuff.
