The present invention relates to a screen magnification system capable of enlarging a small screen to a large screen and having a three-dimensional effect. In particular, the present invention relates to a screen magnification system capable of enlarging a screen generated from an existing image generator to a desired size and displaying it in three-dimensional effect.

Today, with the development of the information industry, the demand for an image display means having a larger screen has been increasing, and in order to satisfy this demand, an image is implemented on the screen by passing a light beam through the image element and projecting it on the screen. Image projection systems such as projection TVs have been proposed.

That is, a flat panel display that can realize a large screen with a small thickness instead of a conventional CRT display having a limited screen size and a large system has attracted attention. Such flat panel display devices include a liquid crystal display (LCD), a plasma display panel (PDP), a projection system, and the like, and a display method using projection for a large screen is now mainstream. In addition, there is a great demand for a wall-mounted display system that can hang on a wall with less space while displaying a large screen.

In general, an LCD projection system projects light emitted from a light source onto an LCD panel and images of the LCD panel are imaged on a screen using a projection optical system to view an image formed on the screen. When the projection TV system is constructed by directly projecting the image of the LCD panel on the rear screen, the projection distance between the screen and the projection optical system must be secured, so that a large amount of space is required behind the screen, and the size of the projection TV system becomes very large. There is this. The LCD projection TV system usually has a configuration as shown in FIG.

The LCD projection TV system shown in FIG. 1 includes a light source 11, an LCD panel 12, a projection optical system 13, a reflector 14, and a back screen 15. The light source 11 generates light to irradiate the LCD panel 12. The LCD panel 12 displays an image by adjusting the transmittance of light incident from the light source 11 according to the image signal. The projection optical system 13 enlarges and projects an image incident from the LCD panel 12 and forms an image on the rear screen 15 so that the viewer can view an image formed on the rear screen 15. In this case, the image projected by the projection optical system 13 is reflected by the reflector 14 and proceeds toward the rear screen 15 to form an image on the rear screen 15. Here, when the projected image is projected by the reflector 14 directly from the rear of the rear screen 15 without breaking the path of light, as shown by the dotted line, the thickness A of the system becomes very large, so that the reflector ( 14), the system thickness can be reduced to B by changing the path of light.

In general, the video room is more than 2M away from the TV screen, but in this case it is not economical to occupy a lot of expensive rent place, and in the PC room, such as watching a TV or monitor screen from a close position In the same case, when the monitor is viewed up close, the image particles are intact and resolution is reduced. Especially, in the case of PDP (Plasma Display Panel), the larger the screen, the coarser the resolution, and the lower the resolution. It is known to add weights.

In addition, it is known that watching a movie or sports broadcast for a long time, such as watching at an angle of about 10 ° downward, is less fatigued, but the larger the monitor, the more limited the installation of such a required structure. In addition, when a large screen is required as required, when viewing a magnification device in front of the video monitor, the long distance observation is required in proportion.

An example of a technique for satisfying such a request is disclosed in Korean Utility Model Publication No. 20-0201662.

In Fig. 2, the vertical image box is provided with a video monitor 2 composed of a PDP or liquid crystal monitor and a large monitor on the upper part of the vertical box 1, which is configured vertically and vertically, and is configured downward in the screen section in which the image is displayed. The reflector 3 was configured to be positioned at the lower end of the viewer 7 than the eye level of the viewer 7.

The reflecting mirror 3 is connected to the rotating shaft 5 at the central portion of the rear surface and fastened to the angle adjusting device 6 to enable vertical angle adjustment.

In addition, at the lower end of the reflector 3, speakers are coupled to both sides, and a mounting table is provided in which various amplifiers and the like can be built in the interruption.

However, in the technique disclosed in the above publication, since the video monitor 2 is mounted on the top of the box 1 as shown in Fig. 2, the video monitor 2 is mounted in correspondence with its load according to the size of the video monitor 2. There was a problem that was complicated.

In addition, in a game room or the like, a normal user increases the intensity for operating each operation button according to the type of game or the progress of the game, and in many cases, the box 1 itself is shaken. In such a case, in the structure shown in FIG. 2, there was a risk that the video monitor mounted on the top would fall and damage the human life.

In addition, in the structure shown in FIG. 2, only one method for adjusting the viewing angle is presented, and there is no change in the enlargement of the screen.

The structure shown in Fig. 6 can also be used in a video room, a personal movie theater, a PC room, or the like.

In addition, in the structure shown in FIG. 6, an example in which an observer sits in a chair in a correct position is described, but the present invention is not limited thereto. For example, depending on the viewing state of the viewer, for example, when viewing obliquely lying or In the case of lying down viewing, the mounting state of the system shown in FIG. 6 may be easily installed by simply changing the viewing state of the viewer.

As described above, according to the screen magnification system of the present invention, since a large screen can be generated using a small image generator, it is sufficient to provide a small image generator in an entertainment room, a video room, a PC room, and the like, thereby reducing the installation cost. The effect that can be obtained is obtained.

In addition, according to the screen magnification system of the present invention, since the existing installation space of the large-scale image generator can be replaced by a small image generator, the effect that the installation space can be utilized effectively is obtained.

Further, according to the screen magnification system of the present invention, since the three-dimensional effect of the image is formed by the first and second reflecting members, the effect that the user can view the image with a more realistic sense is also obtained.

In addition, according to the screen magnification system according to the present invention, when using a small LCD panel, it is also possible to further reduce the weight of the system to build a more stable system.
