| Abstract: | This paper discusses the electromagnetic compromising emanation of TFT LCD. According to the source of electromagnetic compromising emanation,the working principles of LCD panel,driver circuit,VGA interface,DVI interface,video pre-processing circuit are described separately,including the features of signal transfer in these components. Based on study of electromagnetic compromising emanation from components of LCD,the possibility and difficulty for receiving and recovering the emanated information are analy... |
