AN APPARATUS AND ASSOCIATED METHODS

摘要

In one or more embodiments described herein, there is provided an apparatus comprising a support layer (1 10), a plurality of pixels, and a switch (1 12). The pixels are formed using an arrangement of respective liquid-phobic elements disposed on the support layer (1 10). The arrangement of the liquid-phobic elements is configured so as to be able to provide, when interacting with a liquid on the support layer (1 10), one or more associated plastron regions to provide a first pixel optical state. The switch (1 12) is configured to be able to selectively modify one or more of said associated plastron regions to provide a second pixel optical state.
