Device for removing electric field of display |
摘要 |
A device for removing electric field of a display according to the present invention comprises: a voltage generator connected to a horizontal deflection output circuit of a CRT and generating an antiphase reverse pulse having a frequency band equal to that of a horizontal output pulse; a reverse pulse sensor made of a conductive material, insulated at a given location in the front part of the CRT, and generating the reverse pulse around the CRT; and a connector for detecting the reverse pulse of the voltage generator, connected to ground at one end thereof and the reverse pulse sensor at the other end thereof, and sending the reverse pulse to the reverse pulse sensor.
