The present invention relates to an LCD module mounting structure in which the size of the LCD module is reduced by elastically pressing and fixing, thereby reducing the mounting space.

Cathode ray tube (CRT), one of the widely used display devices, is mainly used for monitors such as TVs, measuring devices, and information terminals.However, due to the weight and size of the CRT itself, Could not respond actively to the demand. In order to replace the CRT, LCD modules having advantages of small size and light weight have been actively developed. Recently, the LCD module has been developed enough to perform a role as a flat panel display device, and the demand for LCD modules is increasing.

In general, most notebook computers currently on the market employ LCD modules as display devices. Therefore, in the situation where notebook computers are becoming thinner and lighter, the slimmer and lighter LCD modules become an essential requirement. This is because LCD modules occupy the largest area and weight in notebook computers.

As an attempt to reduce the area of the LCD module has been studied how to mount the LCD module in the case of the notebook computer (hereinafter referred to as "note PC case").

Also, referring to FIG. 2, an LCD module applied to a side mounting method is shown. As shown, the end of the mounting tab 21 formed on the side of the LCD module 1 is bent to be parallel to the side of the LCD module 1, so that this mounting tab 21 of the note PC case 50 The LCD module 1 is fixed by combining the other side of the bracket 23 having one side fixed to the bottom by using the nut 20.

However, when the LCD module is mounted according to the conventional method, some problems occur.

First, in the case of the top mounting method, an outer size of the LCD module is increased by the mounting tab, thereby increasing the size of the case.

In addition, when using the side mounting method, the mounting space is somewhat reduced compared to the top mounting method, but because the mounting tab formed on the side of the LCD module is fixed to the bracket with a nut, due to the width of the mounting tab and the thickness of the bracket Small size reduction effect. In addition, there is a problem that the mounting work is difficult because the nut is fitted from the side.

On the other hand, in any case, the external shock applied to the case is transmitted to the LCD module as it is, and thus there is a problem that the display quality of the display is deteriorated.

Therefore, an object of the present invention has been made in view of the above problems, to reduce the space for mounting the LCD module to the case.

Another object of the present invention to provide a mounting structure of the LCD module resistant to shock and vibration.
