Description

Structure of a PC having a LCD

The present invention relates to a structure of an LCD integrated PC, and in particular, a PC and LCD which can be operated by a wireless keyboard having a mouse function are integrally formed, and air inlet holes are formed on the side of the PC, and an air inlet guide is formed on the rear of the LCD. It is related with the structure of the LCD integrated PC which installed the heat insulating material.

After personal computers emerged in 1976, PCs developed in earnest in the early 1980s, when many computer companies opened their own PC architectures as IBM computer company IBM entered the PC market. Using the computer's configuration and structure, the company made an IBM-compatible model, which became compatible with IBM PCs.

In other words, most commonly referred to as PCs refer to IBM PC compatible models, as well as assembled PCs, which are made up of IBM compatible models regardless of which company's components are used. have.

The configuration of the PC can be largely divided into internal devices and external devices. The internal devices are mounted inside the main body of the PC, and the main board, CPU, RAM, hard disk, CD-ROM drive, floppy disk drive, graphics card, There are sound cards, modems, etc., and the external devices are peripheral devices of the PC main body such as monitors, keyboards, mice, speakers, and printers.

Then, briefly look at the internal configuration of a general PC, as shown in Figure 1, the main board 10, the CPU 11, RAM 12, the input unit 13, the data storage unit ( 14), modem 15, sound card 16, and graphics card 17.

Here, the main board 10 is equipped with a CPU 11, a RAM 12, etc. as a main board, and directs the flow of all data related to the driving of the PC. The CPU 11 executes a command for processing data and transfers and controls the data to an external device. The RAM 12 stores data currently being worked by the CPU 11 as a data work area (ie, memory). The input unit 13 processes data input through a keyboard, a mouse, and the like, and informs the CPU 11. The data storage unit 14 includes a hard disk for storing a program or data, a floppy disk drive for controlling a floppy disk that stores programs and data but is smaller than the hard disk and is easy to install and remove, and optically. There is a CD-ROM drive that reads data recorded on a CD-ROM. The modem 15 is a device for computer communication. The sound card 16 is an adapter that handles sound output. The graphics card 17 is an adapter for processing of outputting pictures or characters on the monitor screen.

However, when configuring a PC as described above, a lot of cables are required to connect the PC main body and peripheral devices (ie, external devices) with each other, and the environment around the PC is very complicated. In general, many people use PCs on their desks, but they take up a lot of space due to their peripheral devices.

In order to solve this inconvenience, a PC having a structure in which a monitor and a PC main body are integrated has been developed. In this case, EMI (Electro Magnetic Interface) regulations (for example, noise emitted from a device) do not affect other devices. Shall be manufactured so that it is suitable for the test items for conductive noise transmitted to other equipment by power line).

That is, the monitor and the PC main body must be formed in one piece in consideration of problems such as emission of radioactive noise and electromagnetic wave emission, durability, productivity, and the like at the coupling portion where the monitor and the PC main body are connected.

As shown in FIG. 2, the monitor-integrated PC having such a structure includes a monitor 20 and a PC main body 21. In order to solve problems such as emission of radioactive noise and emission of electromagnetic waves, the monitor 20 is provided. Is located above the PC main body 21, and the PC main body 21 is made to have durability in order to withstand the load of the cathode ray tube that the monitor 20 has. Then, the back cover 22 for covering both the monitor 20 and the PC main body 21, the monitor front cover 23 for covering the front part of the monitor 20, and the front part of the PC main body 21. It further comprises a PC front cover 24 for covering the cover, and a cover 25 for covering the speaker.

However, this structure also has a disadvantage in reducing the installation space and the weight of the PC is heavy.

On the other hand, in order to solve the above disadvantages (that is, to minimize the installation space and weight), as shown in Figure 3, a thin LCD 30 as a monitor on one side of the PC main body 31 An integrally formed structure has also been developed.

However, although the structure of FIG. 3 is improved from the structure of FIG. 2, it is also required to occupy the space as large as the size of a general PC body with the LCD mounted on a general PC, and for other peripheral devices (ie, a keyboard, a mouse, etc.) Space was required, and there was still a problem in that a cable for connecting the PC body and other peripheral devices to each other was still needed. In addition, by changing the optical characteristics such as color, transparency, etc. for the LCD by the heat generated from the main board, power supply, etc. in the main PC main body, there is a problem of lowering the image quality of the LCD and shortening the lifespan.

In order to solve the problems described above, the present invention is formed by integrally forming a PC and LCD that can be operated by a wireless keyboard having a mouse function, wires for connecting a conventional PC and peripheral devices (keyboard, mouse, monitor, etc.) It is not necessary to provide a clean atmosphere, but also to provide a structure of an LCD-integrated PC that is excellent in space utilization due to its small volume.

In addition, the present invention is to provide the power supply through the external AC / DC conversion adapter in the LCD integrated PC and to install heat insulators and heat shields on the back of the LCD to prevent heat transfer to the LCD and to form air inlet holes on the side of the PC The air inlet guide is formed in the heat shield plate to prevent the rise of the internal temperature of the PC by letting out the air introduced along the air inlet guide through the corresponding air inlet guides to the cooling pen, thereby preventing the LCD from rising due to the heat generated inside the PC. The purpose of this is to prevent degradation and shortening of the service life.
