The present invention relates to a mounting frame that is mounted to a system in combination with a flat panel display module. More particularly, the present invention relates to a flat panel display device in a system such as a notebook computer without using a screw. It relates to a mounting frame that can be fixed by mounting the module in a side mount (side mount) method.

In recent years, as the society enters the information age in earnest, the display field for visually expressing electrical information signals has been rapidly developed. In response, various reputations with excellent performance of thinning, light weight, and low power consumption have been developed. A flat panel display device has been developed to quickly replace the existing cathode ray tube (CRT).

Specific examples of such a flat panel display device include a liquid crystal display device (LCD), a plasma display panel device (PDP), a field emission display device (FED), and an electroluminescent display device. (Electro luminescence Display device: ELD) and the like, these are commonly used as a mandatory element of a flat panel display panel that implements an image, the flat panel display panel is a pair of inherent light emitting or polarizing material layer between Has a structure in which a transparent insulating substrate is bonded to each other.

Recently, an active matrix for controlling each of them independently using a switching element such as a thin film transistor (TFT) after forming pixels, which are basic units of image expression, in such a flat panel display panel. The active matrix type is widely used because of its excellent video reproducibility and color reproducibility, and these flat panel display panels are modularized by various mechanical means and mounted in separate systems, such as computer monitors, laptops, and laptop computers. It is used as a display product of a display screen or a TV of a portable information processing device.

In this case, in order to fix the flat panel display module to an external system, a mounting frame is mobilized as a separate intermediate structure, which is mounted on the system in an assembled state with the flat panel display module, thereby stably coupling and maintaining the flat panel display module and the system. Be sure to

On the other hand, for the convenience of description, the meaning of some terms is clearly defined. First, the flat panel display module refers to a flat panel display panel as well as a minimum functional and mechanical coupling element necessary for realizing its image. According to the module means such as the driving circuit of the panel and various frame members for integrating them, and the light distribution device, the system means a part or the whole of the display product on which the flat panel display module is mounted. For example, a case for wrapping and storing the remaining portion of the flat panel display module in a notebook or a TV while the display surface is opened.

1 is an exploded perspective view showing a liquid crystal display module and a mounting frame for mounting the same on a notebook as a specific example of a general flat panel display module.

As shown therein, the liquid crystal display module 10 includes a liquid crystal panel 12. The liquid crystal panel 12 is a light-receiving element that does not have a light emitting element. In the back of the panel 12, a backlight assembly having a fluorescent lamp or the like as a light source is provided as a light distribution device. As a mechanical element for integrating them, a cover bottom is coupled to the back of the support main having a rectangular frame shape to define an accommodating space, and the backlight assembly and the liquid crystal panel 12 are stored in this order. The top cover 14 covering the front edge of the liquid crystal panel 12 is covered and coupled to the support main and cover bottom.

Therefore, the liquid crystal panel 12 is modularized into the support main, cover bottom, top cover 14, etc. together with the backlight assembly.

In addition, the system includes a notebook screen display unit 24 configured to be folded or unfolded by being connected to a notebook main body 20 and a hinge 22 provided with a keyboard, which is an exterior when folded with the main body. The rear case 26 for accommodating the liquid crystal display module 10 and the edge of the liquid crystal display module 10 to expose the display surface of the liquid crystal display module 10 may be formed while the inner surface facing the main body forms an open box shape. It includes a top bezel 28 that is coupled to the rear case 26 borders.
