a bonding material configured to bond the damping portion to the front cover, and

wherein a plurality of damping slits is formed in the main bracket that overlap one another in a radial direction about a portion of the main bracket to which the fixing portion of the forward/backward vibration damper is attached.

2 . The haptic display according to claim 1 , wherein:

the main bracket includes a damper fixing groove configured to receive the fixing portion of the forward/backward vibration damper;

the damping fixing groove includes a rotation preventing protrusion configured to limit rotation of the fixing portion of the forward/backward vibration damper with respect to the main bracket; and

the fixing portion of the forward/backward vibration damper includes a female thread configured to be threadedly coupled with an assembling screw extending through the main bracket at a rear side of the main bracket.

3 . A haptic display for a vehicle comprising:

a front cover having a front surface;

a display panel attached to the front surface;

an oscillation actuator attached to the display panel;

a main bracket positioned behind the front cover and spaced apart from the oscillation actuator and the front cover;

a forward/backward vibration damper installed between the main bracket and the front cover to dampen vibrations between the front cover and the main bracket in a forward/backward direction;

an upward/downward vibration damper installed between the main bracket and the front cover to dampen vibrations between the front cover and the main bracket in an upward/downward direction; and

a rear cover fixed to the main bracket and configured to surround the main bracket behind the front cover,

wherein the upward/downward vibration damper comprises a floating member having a lower flange formed of a vibration insulator material and having an upper surface on which the front cover is supported, and an upper flange having a lower surface via supported on the main bracket.

4 . The haptic display according to claim 3 , wherein:

the front cover includes a cover protrusion that protrudes rearwardly from the front cover and is seated on an upper surface of the lower flange of the floating member; and

the main bracket includes an upward/downward movement guide groove in which the floating member is positioned and through which the cover protrusion extends to be seated on the upper surface of the lower flange, the upward/downward guide groove and the floating member cooperating such that only the lower surface of the upper flange is supported by the main bracket; and

the cover protrusion and portions of the floating member other than the lower surface of the upper flange are spaced apart from the main bracket.

5 . The haptic display according to claim 4 , wherein the main bracket includes a support protrusion that widens a surface of main bracket on which the lower surface of the upper flange of the floating member is supported.

6 . The haptic display according to claim 1 , wherein the rear cover is spaced apart from the front cover when attached to the main bracket.

7 . The haptic display according to claim 6 , wherein:

the rear cover includes a first forward/rearward restraint protrusion and the main bracket includes a second forward/rearward restraint protrusion which cooperate to restrain forward/rearward movement of the rear cover and the main bracket with respect to each other; and

one of the first forward/rearward restraint protrusion and the second forward/rearward restraint protrusion includes at least one linear contact protrusion to form a linear contact state together with the other one of the first forward/rearward restraint protrusion and the second forward/rearward restraint protrusion.

8 . A haptic display for a vehicle comprising:

a front cover having a front surface;

a display panel attached to the front surface;

an oscillation actuator attached to the display panel;

a main bracket positioned behind the front cover and spaced apart from the oscillation actuator and the front cover;

a forward/backward vibration damper installed between the main bracket and the front cover to dampen vibrations between the front cover and the main bracket in a forward/backward direction;

an upward/downward vibration damper installed between the main bracket and the front cover to dampen vibrations between the front cover and the main bracket in an upward/downward direction; and

a rear cover fixed to the main bracket and configured to surround the main bracket behind the front cover,

wherein the rear cover is spaced apart from the front cover when attached to the main bracket, and

wherein:

the rear cover includes a first parallel-direction restraint protrusion and the main bracket includes a second parallel-direction restraint protrusion which cooperate to restrain movement of the rear cover and the main bracket with respect to each other in directions parallel to the display panel;

the first parallel-direction restraint protrusion comprises an outer arc-shaped restraint portion configured to receive and confine the second parallel-direction restraint protrusion and a guide portion that extends downwardly from the restraint portion and is configured to guide the second parallel-direction restraint protrusion into the guide portion;

the second parallel-direction restraint protrusion comprises an inner arc-shaped restraint portion configured to be received in the outer arc-shaped restraint portion; and

the inner arc-shaped restraint portion includes a plurality of linear contact protrusions configured to form a linear contact state together with the outer arc-shaped restraint portion.
