CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of Korean Application No. 2003-26799, filed Apr. 28, 2003, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
However, it is difficult for the conventional display 120 to be compactly formed since the first casing 121 should be larger than the display unit 123 by an interval �a� which is the thickness of the fastening projection 128. Further, when the first casing 121 is made by the synthetic resin mould, a manufacturing process becomes complicated since a separate nut member 129 having a fastening hole 129 a is required to be mounted in a fastening projection 128 in order to strengthen the screw-coupling of the screw S.
SUMMARY The present invention has been made to overcome the above-mentioned problems of the prior art. Accordingly, an aspect of the present invention provides a display of a portable electronic device, of which a casing enclosing a display unit is minimized in size for compactness of the device.
FIG. 3 is a sectional view of the assembled conventional display, cut along line I�I of FIG. 2;
FIG. 8 is a sectional view showing an inner structure of the display, cut along line II�II of FIG. 7 in accordance with an embodiment of the present invention; and
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Several embodiments of a display according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Further, in referring to the elements having the same structure and function as those of a portable electronic device of FIGS. 1 to 4, the elements will be cited by the same reference numerals.
The fastening projection 328 protrudes from an inner wall of the second casing 327 toward the first casing 321, and has a fastening hole 328 a for screw-coupling with the screw part 329 a of the fastening member 329 when the casings 321, 327 are connected. The fastening hole 328 a is formed in the fastening projection 328 corresponding to the first and the second holes 321 a, 327 a. It is preferable that the fastening projection 328 is distanced by a predetermined interval �b� (see FIG. 8) from the inner wall of the frame 327 c of the second casing 327. It is more preferable that an interval �c� (see FIG. 8) between an inner wall of the first casing 321 and an end of the fastening projection 328, is the same as a thickness �t� (see FIG. 5) of the display unit 123. In this embodiment of the present invention, when the thickness �t� of the display unit 123 is the same as the interval �c� between the inner wall of the first casing 321 and the end of the fastening projection 328, the rear side of the display unit 123 is supported in contact with the end of the fastening projection 328.
Accordingly, when connecting the first and the second casings 321, 327, the display unit 123 is disposed in a space between the fastening projection 328 and the inner wall of the first casing 321, and accordingly, the screw part 329 a of the fastening member 329 is positioned between the display unit 123 and the second casing 327. Therefore, since no separate escape space �a� (see FIG. 2) is necessary for the screw part 329 a of the fastening member 329, an inner side of the first casing 321 can be the same size as an outer frame of the display unit 123.
In this case, a plurality of notch units 124 a (see FIG. 5) are formed on the control board 124 which is relatively easier to provide than for the display unit 123 to be made smaller, to receive the screw part 329 a of the fastening member 329, and the end of the fastening projection 328. The notch units 124 a preferably substitute for the conventional escape space �a� (see FIG. 2). Therefore, the display 320 can have a narrower width.
Meanwhile, to reduce the size of the notch unit 124 a of the control board 124, enough space for receiving the control board 124 is required inside the second casing 327. Accordingly, a distance �d� between the fastening projections 328 needs to be maximized. To accomplish this, the fastening projection 328 is formed as thin as possible, but with a sufficient thickness so that a screw line (not shown) can be formed on an inner circumference of the fastening hole 328 a having a minimum pitch for the screw-coupling with the screw part 329 a of the fastening member 329. Additionally, the fastening projection 328 should be disposed as near as possible to the second hole 327 a of the second casing 327. For the above two conditions, in this embodiment of the present invention, only a center 328 b (FIG. 6) of one side of the fastening projection 328, which opposes the second hole 327 a of the second casing 327, protrudes a predetermined length toward the second hole 327 a. Because the fastening projection 328 is formed by a mould using a sliding core, it is hard to precisely form the fastening projection 328 together with the second casing 327 using only general molding due to a narrow space between the fastening projection 328 and the second hole 327 a of the second casing 327. The forming method is a well-known one in molding, therefore, a detailed description thereof will be omitted. The shape of the fastening projection 328 is not limited to the described embodiments. One will understand various possible changes may be made such as the fastening projections 328 having uniform thickness.
At a free end of the outer frame 321 c of the first casing 321 is formed an insert unit 321 d which is inserted between the fastening projection 328 and the outer frame 327 c of the second casing 327 when the first and the second casings 321, 327 are connected with each other (see FIG. 8). It is preferable that the first hole 321 a is formed in the insert unit 321 d. Therefore, the interval �b� between the fastening projection 328 and the opposing inner wall of the outer frame 327 c of the second casing 327, is preferably the same as the thickness of the insert unit 327 d. Accordingly, when the first and the second casings 321, 327 are connected, the outer frames 321 c, 327 c thereof forms a plane, and therefore, the second casing 327 is prevented from being enlarged by the fastening projection 328.
As shown in FIG. 5, when one side of the hinge unit 130 is fixed inside the display 320, connection holes 321 b, 327 b are aligned with each other on one side of the first and/or the second casings 321, 327. Therefore, the hinge unit 130 is attached to the first and the second casings 321, 327 by penetrating the connection holes 321 b, 327 b. In this case, the display unit 123 is supported by contact on the inner wall of the outer frame 321 c of the first casing 321, except one side that opposes the hinge unit 130. Accordingly, at least one block protrusion 321 e is preferably formed on the first casing 321 to prevent the display unit 123 from moving toward the hinge unit 130.
