Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal monitor having a multiplex function of a normal liquid crystal monitor and a projection function of a projector.

[0002]

2. Description of the Related Art In general, liquid crystal monitors are characterized by saving power, preventing radiation leakage, and taking up less space. They are superior in terms of operation and function as compared with conventional vacuum tube monitors. I can say. However, at present, liquid crystal monitors are by far more expensive than vacuum tube monitors. Therefore, it is often difficult for all liquid crystal monitors to replace vacuum tube monitors. A study of consumer sentiment suggests that a product with multiple functions finds value in the function, even if it is a little expensive, and does not care much about the price when making a selection. This awareness is a major factor in future product development, and it can be said that expanding the functions of LCD monitors can increase their market share.

In general, the prior art comprises, like the embodiment shown in FIG. 1, a leg seat 11 and an outer frame 12 whose angle can be adjusted, and the size of the outer frame 12 corresponds to that of the monitor main body 2. When the monitor body 2 is fitted and fixed, it becomes a liquid crystal monitor whose angle can be adjusted, and simply receives a signal from a computer and displays it.

When the switch is placed, the switch can be put into a heat dissipation fan to directly project the image.

[0006] In the above-mentioned liquid crystal monitor device, a U-shaped back cover corresponding to the size of the screen frame of the monitor main body and three edges of which fit exactly,
A back cover that completely covers the electronic element on the screen frame by the edge and has a back cover hole in the center,
A monitor main body can be configured by combining with the screen frame, and a monitor lamp can be provided in an outer frame instead of the monitor lamp provided in the monitor main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid crystal monitor according to the present invention comprises a pedestal 1 and a monitor main body 2, as shown in FIG. FIG. 2 shows a state where the monitor main body 2 is separated from the pedestal 1. FIG. 3 shows the monitor main body 2 of FIG. 2 rotated 180 degrees, and shows a screen frame 21 and a back cover 22.

The screen frame 21 has a frame shape, a conventional liquid crystal screen 211 in the center, a monitor light 212 above the inside, and a monitor light code 2121 connected to a changeover switch 213. At least one radiating fan 214 is provided on the inner wall on the opposite side of the monitor lamp 212, and the radiating port 2141 corresponding to the radiating fan 214 is configured to circulate air. A fan cord 2142 (not shown) is connected to the above-mentioned changeover switch 213 so that the fan cord 2142 can be connected to a power cord.

A control board 215 is provided inside the side wall, and a computer connection terminal 2 is provided on the board.
151, which fits into a terminal connected to the computer (shown on the right outside). The control board 215 has a rectifying / transforming electronic circuit, and a radiating fan 214 and a monitor lamp 2 are provided respectively.
It is connected to 12 power supplies.

The back lid 22 is of a frame type, the size of which corresponds to the above-mentioned screen frame 21, and has a back lid hole 221 corresponding to the screen 211 at the center (a transparent plate is attached if necessary). Above it, a back lid edge 222 is bent in three directions. This is devised for the purpose of covering the electronic elements on the screen frame 21 described above. When these are assembled, the state shown in FIG. 2 is obtained. Note that, instead of the monitor light 21 provided in the monitor main body 2, a monitor light may be provided in the outer frame.

When practicing the present invention as shown in FIG.
The monitor main body 2 is fitted into the outer frame 12 of the pedestal 1 to provide a conventional liquid crystal monitor. At this time, when the changeover switch 213 is switched to the monitor light 212, an image based on a signal from the computer is displayed on the screen 211 by the action of the light guide plate 13.

When the projection function is to be used, the monitor body 2 is taken out of the outer frame 12, placed on a data base of a projector (overhead projector) in a state as shown in FIG. When the mode is switched to 214, a signal from the computer is received at the computer connection terminal 2151 and is projected on the screen 211, so that the image can be projected on the screen of the projector.

When the monitor main body 2 is inserted into the outer frame 12, the switch 213 is automatically turned on.
When the switch 12 is turned on to become a normal liquid crystal monitor, and the monitor main body 2 is removed from the outer frame 12, it automatically switches to the heat radiating fan 214 side, receives a signal from the computer, and operates the projection function to project an image. It can also be.

[0014]

According to the present invention, it is possible to provide a conventional liquid crystal monitor device with a projection function, which is a great breakthrough in technology for manufacturers and can bring considerable benefits to consumers. .
