  • This study attempts to characterize the radiated compromising emanations from four typical LCD TV sets, in particular the predictability of format and timing parameters. Three were found to emit clear UHF RF signals visually related to the displayed image, from the LVDS link between display controller and LCD panel. Although the input signals to all four products followed the same TV standard, the timing parameters of their emanations differed substantially. Some also frequency-modulate their… CONTINUE READING
