Abstract

PURPOSE:To provide a multi-functional liquid crystal TV of projector type by building the system from a transmission type liquid crystal TV and a back- light device or a projector. CONSTITUTION:A transmission type liquid crystal TV 1 has a TV receiving function, i.e., can respond to the input of video input signal. When this transmission type liquid crystal TV 1 is watched, it is fixed to a specified position on a back-light device 2, and an image is produced by casting light from the back. When an enlarged image of large format is to be viewed, on the other hand, the transmission type liquid crystal TV 1 is set in the specified position on a projector 3 followed by casting of the specified light from the back, and thereby the image of the TV 1 clan be projected enlargedly on a screen.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmissive liquid crystal television and a projector type liquid crystal television comprising a projector capable of enlarging and projecting an image with the transmissive liquid crystal television as an image plane.

[0002]

2. Description of the Related Art A battery-powered transmissive liquid crystal television has been used in the past, but a small screen and a screen size suitable for full-scale use have a poor yield and are very expensive. I have not used it. Further, although there has been a liquid crystal projector using a liquid crystal for a large screen, it has been difficult to make it portable because it is heavy and requires a power source.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is a multifunctional device that can be used as a portable liquid crystal television in one portable type or as a large screen type. The present invention provides a projector type liquid crystal television having the above.

[0004]

In order to solve the above-mentioned problems, the present invention provides a transmissive liquid crystal television having a television image receiving function and capable of inputting a video input signal, and to see this transmissive liquid crystal television. A system comprising a backlight device to be used, and a system comprising the transmissive liquid crystal television and a projector for enlarging and projecting an image of the transmissive liquid crystal television on a screen. .

[0005]

With the above construction, the projector-type liquid crystal television according to the present invention, when watching the television,
Using a transmissive LCD TV attached to a backlight device,
When used for a large screen, by using a projector that magnifies and projects the image of the transmissive LCD TV, one transmissive LCD TV can realize two functions of a portable TV and a large screen TV. Can be done.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of an essential part of an embodiment of the system configuration of a project type liquid crystal television according to the present invention. In the figure, 1 is a transmissive liquid crystal television having a television image receiving function and capable of inputting a video input signal, 2 is a backlight device, and 3 is a projector. When viewing the transmissive LCD TV 1, this transmissive LCD TV 1
An image can be obtained by attaching the to the predetermined position of the backlight device 2 and applying light from the back surface. When viewing a large enlarged image, set the transmissive liquid crystal television 1 at a predetermined position on the projector 3,
An image of the transmissive liquid crystal television 1 can be enlarged and projected on the screen by applying a required light from the back surface. By incorporating the function of the VTR 4 in the projector 3, it is possible to record a required screen of the transmissive liquid crystal television 1, or by inputting a signal from the VTR 4 to the transmissive liquid crystal television 1. The VTR image can be enlarged and projected on the screen.

[0007]

As described above, in the projector type liquid crystal television according to the present invention, when the television is viewed, the transmissive liquid crystal television is attached to the backlight device, and when used for a large screen, By using a projector for enlarging and projecting an image of this transmissive liquid crystal television, one transmissive liquid crystal television can realize two functions of a portable television and a large screen television.
