Description

LCD Monitor Device {LCD MONITOR APPARATUS}

The present invention relates to an LCD monitor device, and more particularly, to reduce the number of assembly processes by modifying the LCD module for displaying a screen and the method of mounting a case in which the LCD module is accommodated, and the area of the case versus the LCD module. The present invention relates to an LCD monitor device having a lighter weight and a smaller size by making the areas of the same.

Recently, with the development of highly integrated and high performance semiconductor devices and the development of the electric and electronic industries, the development of information processing apparatuses capable of high-speed processing of information is also rapidly progressing.

There are many different types of information processing devices. For example, desktop computers, which are frequently used in daily life and work, and laptop computers, which are portable computers, have been steadily upgraded recently.

Here, a laptop computer, which has recently attracted attention due to its light weight, thinness, and low power consumption, cannot be used with a cathode ray tube type monitor commonly employed in a desktop computer because its purpose is a portable information processing device. In addition, the LCD module that can support high resolution is used as a monitor.

As such, the laptop-type computer employing the LCD module is generally composed of a computer body and a monitor device. The monitor device receives an LCD screen displaying information processed by the computer body and a case protecting the front and rear of the LCD module. It consists of.

Here, the case is divided into a front case for fixing the remaining area except the effective screen display area of the LCD module and a rear case for supporting and fixing the LCD module.
