Recent displays are divided into multiple areas to meet the requirement for high-resolution and transmit multiple pixel information simultaneously. Therefore, it is difficult to apply the conventional TEMPEST attack to such high-resolution displays due to the leaked electromagnetic (EM) wave with multiple pixel information. In this paper, we propose a method for reconstructing screen information by separating each pixel information from EM waves in which multiple pixel information is mixed, focusing on the difference in the transfer function of leaking EM waves. In the experiment, the proposed method was applied to a high-resolution display. The screen is divided into left and right by measuring the EM waves at two frequencies with different transmission characteristics. We then demonstrated that the screen could be restored.
