And a bracket mounting structure of an electronic system and a bracket mounting structure of an electronic system for installing a bracket for strength reinforcement in an electronic system coupled to each other at a predetermined angle.

Rapid changes in the environment using electronic systems have led to continuous improvements in the hardware of electronic systems, leading to the multifunctionalization of electronic systems. Therefore, the structural design of the electronic system should be designed considering the convenience of the user with the convenience of production.

Computers that are representatively developed in such electronic systems have been widely used in various forms of computers. In particular, portable computers, such as laptop computers, notebook computers, and palmtop computers, are being widely used because they have mobility in place of desktop computers.

In general, as shown in FIG. 1, portable computer 10 includes a body portion 12 in which various electronic elements are housed. In this case, the electronic elements include a keyboard 14 including a plurality of key switches and at least one printed circuit board having a matrix electrically connected to the key switches, and a central processing unit (CPU) of a computer. And power supplies such as batteries and suitable storage devices such as hard disks or floppy disks. In addition, the portable computer 10 generally includes a display panel portion 16 coupled to be folded into the main body portion 12 through some form of hinge structure. In this case, the display panel unit 16 protects key elements of the keyboard 14 that are exposed to the upper surface of the main body 12 when the upper surface of the main body 12 is covered. It serves as a cover. When the display panel 16 is opened, the display panel 16 serves as a holder for receiving the display 18 seen by the computer user. The display may be formed of a display device such as a video monitor or a liquid crystal display.

When the portable computer 10 is configured as described above, a portion of the display panel 16 supported by the main body 12 to be stably operated should be configured in hardware. In particular, when a flat display such as an LCD (liquid crystal display) is mounted, a display phenomenon occurs in the display panel part due to a spring back phenomenon, which causes a problem in that the display is not normally mounted. And the reliability of falling.

In order to overcome such a problem, as shown in FIG. 2, a bracket 30 is used for the display panel unit 16.
