In this case, in order to transfer the static electricity introduced to the bracket 107 positioned at the rear of the display unit 151, as shown in FIG. 5, at least a part of the circumference of the display unit 1512 and the rear surface 1511 of the display unit is covered. A conductive tape 200 may be further provided.

That is, when the static electricity flowing into the display unit 151 reaches the conductive tape 200 as shown in FIG. 6, the static electricity flowing along the side surface 1512 of the display unit along the conductive tape 200 is transferred to the bracket 107.

The conductive tape 200 wraps from the side surface 1512 of the display unit to the rear surface 1511 of the display unit in a letter B shape as illustrated in FIGS. 5 and 6 so as to contact the support plate 1071 of the conductive material of the bracket 107. . The conductive tape 200 may be formed around the entire display unit 151, or may be formed at the edge of the display unit 151 which is most affected by static electricity as shown in FIG. 5.

The display unit 151 may be configured as a panel unit 1510 for transmitting image information and a signal unit 1515 for transmitting a signal by connecting the panel unit 1510 and the control unit. The signal unit 1515 may use a flexible circuit board or the like, and may catch the static electricity introduced by using a part of the circuit pattern to prevent the signal from being transferred to the display unit 151.

That is, since the edge of the side where the signal unit 1515 is located can prevent static electricity from flowing into the display unit 151 through the signal unit 1515, the signal unit 1515 is formed as shown in FIG. 5. It can only be formed on the opposite corners.

As illustrated in FIG. 4, the bracket 107 forms a stepped portion that is in contact with the side surface 1512 of the display unit 151 to fix the display unit 151 therein so that the rear portion of the display unit 151 is inserted thereinto. It can be provided.

When the size of the seating portion 1073 is formed so that the display unit 151 fits snugly, when the conductive tape 200 is added, the periphery of the display unit 151 is increased by the thickness of the conductive tape 200. Insertion into the portion 1073 may be difficult. As shown in FIG. 7, a recess region 1074 may be formed around the mounting portion 1073 of the bracket 107 so that the display unit 151 to which the conductive tape 200 is added may be inserted.

The recess region 1074 may be formed at a position to which the conductive tape 200 is attached, and may be formed intaglio around the seating portion 1073 as much as a size corresponding to the thickness of the conductive tape 200.

As described above, according to at least one of the embodiments of the present invention, the static electricity flowing into the display unit 151 may be directly taken out of the support unit 1071 of the bracket 107 so that the display unit 151 may be discharged by static electricity. It can prevent damage. In addition, the conductive tape 200 may be attached to the display unit 151 to prevent static electricity from flowing into the display unit 151 without changing the structure of the existing display unit 151.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
