Cathode-ray tube and image display comprising the same

A cathode ray tube, comprising:

• an electron gun for emitting at least one electron beam;
• a mask frame include a mask having a plurality of holes or slits for allowing the at least one electron beam to be transmitted therethrough and a frame to which the mask is attached;
• and
• a panel including a phosphor layer to be scanned by the at least one electron beam transmitted through the plurality of holes or slits of the mask, wherein:
• the panel includes a plurality of stud pins for supporting the frame;
• the frame includes a plurality of elastic supports engaged with the plurality of stud pins;
• at least one of the plurality of elastic supports includes an engagement portion having an engaging hole which is engaged with one of the plurality of stud pins;
• the engagement portion includes a plurality of sliding pieces forming a funnel shape provided in the engaging hole;
• and
• mask frame vibration causes a surface of each of the plurality of sliding pieces to rub against a respective stud pin so as to generate a frictional force for attenuating the vibration of the mask frame.

• wherein:
• the panel includes a plurality of stud pins for supporting the frame;
• the frame includes a plurality of elastic supports engaged with the plurality of stud pins;
• at least one of the plurality of elastic supports includes an engagement portion having an engaging hole which is engaged with one of the plurality of stud pins;
• the engagement portion includes a central portion having the engaging hole, a first side portion separated from the central portion by a first cut, and a second side portion separated from the central portion by a second cut formed on an opposite side to the first cut with respect to the central portion;
• mask frame vibration causes a cut sectional face of the central portion facing the first cut to rub against a cut sectional face of the first side portion so as to generate a frictional force for attenuating the vibration of the mask frame;
• and
• mask frame vibration further causes another cut sectional face of the central portion facing the second cut to rub against a cut sectional face of the second side portion so as to generate a frictional force for attenuating the vibration of the mask frame.

• the frame includes a plurality of elastic supports engaged with the plurality of stud pins;
• at least one of the plurality of elastic supports includes an engagement portion having an engaging hole which is engaged with one of the plurality of stud pins and a fixing portion for fixing the at least one elastic support to the frame;
• the fixing portion includes a first bent portion and a second bent portion bent towards the engagement portion;
• the first bent portion has a fifth bent portion for restricting the engagement portion from moving in a direction away from the fixing portion, and the second bent portion has a sixth bent portion for restricting the engagement portion from moving towards the fixing portion,
• the engagement portion includes a third bent portion bent so as to be in contact with the first bent portion and a fourth bent portion bent so as to be in contact with the second bent portion;
• mask frame vibration causes the first bent portion to rub against the third bent portion so as to generate a frictional force for attenuating the vibration of the mask frame;
• and
• the mask frame vibration further causes the second bent portion to rub against the fourth bent portion so as to generate a frictional force for attenuating the vibration of the mask frame.
