Description

Flat display device, computer, and method for mounting said display device

The present invention relates to an image display apparatus for use in a computer, a computer having the image display apparatus, and a method of mounting the image display apparatus on a computer.

Computers can be classified into various types such as laptop computers and portable computers. Computers are basically provided with an input device, a storage device, a computing device, and an image display device for displaying the calculation results of the computing device.

Cathode ray tubes (CRTs) are mainly used for image display devices or monitors, and liquid crystal displays (LCDs) are mainly used for portable computers.

Recently, however, plasma display panels (PDPs) and field emission displays (FEDs) are being studied, and these displays are still in development due to high power consumption. There is room for application in portable terminals, and in recent years, the laptop computer has been used in place of the CRT, which has less eye fatigue and almost no electromagnetic wave.

The present invention relates to an image display device that can be applied to various computers as described above, in particular, a method and mounting structure for mounting on a case or a housing so as to maximize the display area of a flat panel display device such as a liquid crystal display device having a flat panel structure. It is about.

Under the circumstances as described above, the present invention will be described only for the convenience of description, and particularly, a flat panel display device and a mounting method thereof applied to a portable computer requiring a small volume.

In addition, the present invention describes a liquid crystal display device as a flat panel display device, but may be applied to various image display devices to be developed later.

In general, a portable computer, that is, a portable terminal, as shown in FIG. 1, a main body 100, a case 120 hinged to the main body 100, and an image display device 130 fixed to the case 120. )

The main body 100 is provided with a key input device 110, which is an information input device, exposed, and has a built-in information processing device such as a memory device and a computing device (not shown). In addition, the flat panel display 130 is generally used in a portable computer or a thin monitor because a liquid crystal display (LCD) has an advantage of reducing the installation space.

Although a light guide plate, a polarizing plate, and the like, which are not shown as an actual light distribution device, are included in this specification, they are referred to as light distribution devices.

In addition, in the present invention, the flat panel display device and the case on which the flat panel display device is mounted are collectively called a flat panel display device assembly, and a flat panel display device equipped with a necessary frame such as a support frame in order for the flat panel display device to be coupled to the case. Defined as a module.

Referring to Figure 2 describes the assembly structure of the liquid crystal display device applied to an example of a conventional portable terminal, the case 120 is separated / coupled to the front / rear cases 122, 124, the liquid crystal display device 130 ) Is fixed.

The rear case 124 has an inner surface and an outer surface, and coupling ribs 124a are formed at four points to support each corner of the liquid crystal display 130.

On the other hand, the liquid crystal display device 130 has a liquid crystal panel 132 is located on the front, the light distribution device 134 is attached to the rear of the liquid crystal panel 132, the edge of the liquid crystal panel 132 and the light distribution device Along the support frame 136 is bordered.

After fixing by fastening to the rear case 124 is coupled to the front case 122.

In the side fixing method of the liquid crystal display 130, the coupling ribs 137 are disposed laterally than the front fixing method so that the height of the coupling ribs of the light distribution device is greater than the width d of the coupling piece of FIG. 2. Since t) may be small, it plays a large role in expanding the display area of the liquid crystal panel 132.

However, this method also requires a coupling rib, and thus there remains a problem that non-display areas corresponding to the height (t) of the coupling rib exist on each side.
