Abstract
A displaying apparatus includes a cathode ray tube (CRT), a printed circuit board (PCB) provided at a rear end of the CRT, a CRT socket to electrically connect the CRT and the PCB, a cable coupling part formed adjacent to the CRT socket, a high voltage cable coupled to the cable coupling part, and an electromagnetic wave shielding member provided inside the cable coupling part in contact with the high voltage cable to shield the displaying apparatus from electromagnetic waves generated by the high voltage cable. Thus the displaying apparatus is capable of shielding from electromagnetic waves generated in the process of applying high voltage to the CRT in a simple and effective manner.
Claims22
A displaying apparatus, comprising:
- a cathode ray tube (CRT);
- a printed circuit board (PCB) provided at a rear end of the CRT;
- a CRT socket to electrically connect the CRT and the PCB;
- a cable coupling part formed adjacent to the CRT socket;
- a high voltage cable coupled to the cable coupling part;
- and
- an electromagnetic wave shielding member provided inside the cable coupling part in contact with the high voltage cable to shield the displaying apparatus from electromagnetic waves generated by the high voltage cable.
A cathode ray tube (CRT) socket usable with a displaying apparatus, the CRT socket comprising:
- a first set of electrical connections to be connected with a cathode ray tube;
- a second set of electrical connections to be connected with a printed circuit board;
- and
- a cable coupling part adjacent to the first set of electrical connections to receive a cable carrying a high voltage and having an electromagnetic shield disposed therein to contact the cable and shield electromagnetic waves generated in the cable from exiting the cable coupling part.
A displaying apparatus, comprising:
- a cathode ray tube;
- and
- an electrical connection part including:
- a plurality of electrical connections to connect the cathode ray tube to a circuit board, and
- a cable insertion part adjacent to the plurality of electrical connections to receive a cable carrying a high voltage and to provide the high voltage to the cathode ray tube on at least one of the plurality of electrical connections, and having an electromagnetic shield disposed therein to surround the cable received in the cable insertion part and to shield the displaying apparatus from electromagnetic waves.
