Description

How to fix flat panel display, computer and flat panel display

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 desktop 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 displays 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 to be applied to a portable terminal, and in recent years, the desktop computer has been used in place of the CRT liquid crystal display device with less eye fatigue and little electromagnetic wave generation, and this distinction is becoming thinner.

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, that is, a display unit and an image fixed to the case 120. The display device 130 is formed.

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.

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 which is a display surface on the front surface, a light distribution device 134 is attached to the rear of the liquid crystal panel 132, and the liquid crystal panel 132 and light distribution A support frame 136 is bordered along the edge of the device. In addition, coupling pieces 136a protrude from the side surfaces of the corners of the support frame 136, and coupling pieces 136a are formed to match the positions of the coupling ribs 124a of the rear case 124. have.

In the method of assembling the liquid crystal display device 130 having the above-described configuration to the case 120, the liquid crystal display unit 136a of the support frame 136 coincides with the coupling rib 124a of the rear case 124. The display device 130 is disposed, the coupling piece 136a and the coupling rib 124a are fastened with the screw 138, and then the front case 122 is coupled to the rear case 124.

Here, the method of combining the front surface of the liquid crystal display device 130 toward the rear case 124 with the screw 138 or the like is referred to as a front mounting method, and the assembled structure is defined as a front assembly structure. do.

However, in the front assembly structure of the liquid crystal display device 130, the coupling piece 136a protrudes from the support frame 136 in the liquid crystal display device 130 to occupy space by the width d of the coupling piece. There is a problem that the display area of the liquid crystal panel 132 is reduced.

Therefore, in order to solve the above problems, a method of adopting a side assembly method and a structure for assembling the flat panel display side in recent years has been proposed.

Referring to FIG. 3, the side assembly structure of the liquid crystal display device is described. The case 120 is separated / coupled into the front / rear cases 122 and 124, and a pair of pairs are formed on both sides of the rear case 124. The fastening hole 124b is formed.

The support frame 136 is surrounded by the liquid crystal panel 132 and the light distribution device 134 in the liquid crystal display device 130, while the pair of fastening holes 124b are formed at both sides of the light distribution device 136. A pair of coupling ribs 134a is formed at a position corresponding to the protrusion ribs, and the support frame 136 is cut in such a way that the coupling ribs 134a are not in contact with each other, or is aligned with the holes of the coupling ribs 134a. The hole is formed.

In the fixing method of the liquid crystal display device 130 having such a structure, the liquid crystal display device is disposed on the rear case 124 to provide a screw 138 between the coupling hole 124b and the coupling rib 134a formed on the side surface of the case 124. After fixing by fastening to the rear case 124 is coupled to the front case 122.

The side mounting method of the liquid crystal display device 130 has a coupling rib 137 disposed laterally than the front fixing method so that the non-display area of the liquid crystal display device 130 is smaller than the width d of the coupling piece of FIG. Since the height t of the coupling ribs may be small, the coupling ribs play a large role in expanding the display area of the liquid crystal panel 132.

However, this method does not have a coupling between the front surface of the case 124 and the liquid crystal display device 130, and thus needs to be compensated for.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned demands. The present invention provides a flat panel display with a flat panel display panel and a case fixed at the same time, while minimizing an invalid display area generated when the flat panel display is fixed to a case. It is an object of the present invention to provide a computer equipped with a display device and a method of fixing a flat panel display device to the computer.
