Abstract
A CRT display unit provides for reduced electromagnetic radiation emission by encasing a video amplifier for amplifying image signals sent from a computer and a CRT device for displaying the amplified image signals within a chassis; coating conductive films on the external and internal surfaces of the funnel section of the CRT envelope; covering the circumference of the panel section with a metal rim band; fastening the envelope to the chassis via metal fixtures installed on the rim band; electrically connecting the conductive film coated on the external surface to the rim band by means of a first conductive member; and electrically connecting the space between the rim band on the panel section fastened to the chassis via metal fixtures and the chassis using a second conductive member.
