In this paper we present several examples of video signal recovery from electromagnetic emissions generated by smartphones touchscreens as well as a number of measurements results performed in a specialized laboratory. We aimed the identification of the video signal parameters by using video images that were especially selected to facilitate this process. The measurements were performed by comparing two smartphones that have different display resolutions. In the final part we will also present a method to identify the emission frequencies for these compromising emanations.
