Abstract
A method for improving the resistance of display of OCT equipment to electromagnetic field interference radiated by radio frequency is characterized in that firstly, a shield cover originally mountedon a display control panel is connected with a metal plate by a cop sheet or a copper connecting tape, so that the potential generated by external radio frequency interference of the shield cover is communicated with the ground through the metal plate; Secondly, the coupling interference of 28V/m RF interference to the wire is reduced by connecting magnetic loops in series in the longer traces. The invention solves the problem of anti-radio frequency interference of the display, has simple method, improves the universality of the display, and reduces the requirement on the anti-interference grade of the display.
