ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an LCD (liquid crystal display) fastening method and equipment using common fastening portions suitable for various kinds of color LCDs, and improving the appearance of the display.
This application is based on Patent Application No. Hei 11-111639 filed in Japan, the contents of which are incorporated herein by reference.
2. Description of the Related Art
FIG. 4
is an assembly drawing for explaining a conventional method of fastening the LCD.
FIG. 5
is an enlarged view of portion A in FIG.

With reference to
FIG. 4
, in the conventional LCD fastening method, holes

. In the above structure, first, fastening screws
15
are inserted into bosses
13
(provided in the LCD base
7
) via holes
200
(provided in the brackets
19
) so as to combine the base and brackets. Next, the LCD cover

. The screws
11
are further inserted into holes
20
provided in the brackets
19
. That is, brackets
19
are fastened to LCD

provided in the brackets. Examples of the related conventional technique are disclosed, for example, in Japanese Unexamined Patent Applications, First Publications, Nos. Hei 5-100212, Hei 7-170083, Hei 10-168424, Hei 10-207630, and Hei 11-6998.
The conventional technique has the following problems. The first problem is a difficulty in using common portions suitable for various kinds of color LCD displays
2
of a portable laptop (or notebook) personal computer. The second problem is to have a process of attaching the LCD display
2
using fastening screws inserted from the outside of an external frame, which is not preferable in view of the appearance.
SUMMARY OF THE INVENTION
In consideration of the above circumstances, an objective of the present invention is to provide an LCD fastening method and equipment for using common portions necessary for fastening a color LCD display, that is, common portions suitable for various kinds of color LCD display, thereby omitting the process of attaching the LCD by using screws inserted from the outside of an external frame and improving the appearance.
Therefore, the present invention provides an LCD fastening method comprising the steps of:
attaching brackets to a color LCD using first fastening screws inserted through holes provided in the brackets;
attaching the brackets to an LCD base by inserting second fastening screws through holes provided in the brackets into bosses provided in the LCD base; and
attaching an LCD cover to the LCD base by engaging a predetermined number of latches provided in the LCD cover with corresponding first ribs provided in the LCD base.
The present invention further provides an LCD fastening method comprising the steps of:
attaching brackets to a color LCD by inserting fastening protrusions provided in the brackets into corresponding holes provided in the color LCD;
attaching the brackets to an LCD base by inserting second fastening screws through holes provided in the brackets into bosses provided in the LCD base; and
attaching an LCD cover to the LCD base by engaging a predetermined number of latches provided in the LCD cover with corresponding first ribs provided in the LCD base.
In either method, the step of attaching the brackets to the LCD base may further include engaging insert portions provided in the brackets with second ribs provided in an upper face of the LCD base.
The present invention also provides LCD fastening equipment comprising:
brackets attached to a color LCD by using first fastening screws inserted through holes provided in the brackets;
an LCD base to which the brackets are attached by inserting second fastening screws through holes provided in the brackets into bosses provided in the LCD base; and
an LCD cover attached to the LCD base by engaging a predetermined number of latches provided in the LCD cover with corresponding first ribs provided in the LCD base.
The present invention also provides LCD fastening equipment comprising:
brackets attached to a color LCD by inserting fastening protrusions provided in the brackets into corresponding holes provided in the color LCD;
an LCD base to which the brackets are attached by inserting second fastening screws through holes provided in the brackets into bosses provided in the LCD base; and
an LCD cover attached to the LCD base by engaging a predetermined number of latches provided in the LCD cover with corresponding first ribs provided in the LCD base.
In either equipment, the brackets may further include insert portions engaged with second ribs provided in an upper face of the LCD base.
According to the present invention, the following effects can be obtained.
The first effect is that a common LCD base can be used for various kinds of color LCDs without providing holes for fastening screws in the base, thereby reducing manufacturing man-hours.
The second effect is that a common LCD cover can be used for various kinds of color LCDs without providing holes for fastening screws in the cover, thereby reducing manufacturing man-hours.
The third effect is that the fastening method can be selected by selecting brackets suitable for the relevant color LCD. Therefore, it is unnecessary to provide holes for fitting screws in the LCD base and LCD cover, and a preferable appearance will appeal to users.
