Abstract

PURPOSE:To view a liquid crystal picture by enlarging and projecting if required, by intervening a small-sized liquid crystal TV picture plane in the optical path of a small-sized projector containing an optical system for enlarging image. CONSTITUTION:A white light source 6 and optical lens system 7 are provided inside the box body 4 of a projector and a liquid crystal TV picture 5 is contained between the optical lens system 7 and an enlarging lens system 8. Under this condition, the liquid crystal picture passes the light of the light source just like a slide film and the light is projected upon a screen 10 by means of the enlarging lens system 8. The focal point on the screen can be adjusted when the lens system 8 is moved by using a fine adjustment mechanism 9. Therefore, a small-sized liquid crystal TV picture is viewed after it is enlarged to an optional size, and thus, the usefulness of the luquid crystal TV is increased.

Description

【発明の詳細な説明】 本発明は、小型液晶テレビ全利用する簡便なプロジェク

なサイズに拡大して見られるようにするものである。Conventionally, projection televisions have been used exclusively for large-sized televisions using projection tubes, and it has been impossible to freely enlarge or reduce the size of the television itself. The present invention makes it possible to enlarge the screen to any size and view it using a completed television set.

以下、図面に従って本発明ｔ−＝明する。Hereinafter, the present invention will be explained according to the drawings.

−な簡便なプロジェクタ−で映像の拡大が可能である。On the back of the small liquid crystal television screen 2, there is a reflective plate in the case of a reflective type, and a built-in light source in the case of a transmitted light type. The back part 3 of the liquid crystal panel shown in FIG. 1 is made up of these opaque members on the back and can be rotated 90 degrees backward. usually,
When the TV is to be enjoyed while being carried, the liquid crystal panel back 3 is housed inside the TV. When the panel back 6 is opened backwards, the liquid crystal panel becomes in a state where light from behind the TV is transmitted, and if there is natural light behind the TV, the screen can be viewed as is. Furthermore, in this state, the LCD panel is projecting the TV image moment by moment, just like a photographic slide film, and the image can be enlarged using a simple projector like the one shown in Figure 2. be.

In this state, the liquid crystal screen transmits the light from the light source as if it were a slide film, and is projected onto the screen 10 by the magnifying lens system 8'. Lens systems 7 and 8 are already well known as enlarged image projection optical systems in 8-panel projectors and slide projectors, and have a simple structure and are inexpensive. By moving the magnifying lens system 8 back and forth using the fine adjustment mechanism 9, the entire focal point on the screen can be brought into focus. this .

常に簡便な教育システムが構成できる。By this, an enlarged image of any size is displayed on any screen such as a wall, ceiling, or white paper. Therefore, you can enjoy the sound of a small TV outdoors, enlarge it to a size that is easy to see indoors, and enlarge it even more when a large number of people are watching. The advantage of this small-sized television projector is that when combined with a small-sized liquid crystal television, a projector that is inexpensive, highly mobile, and has a large degree of freedom can be created. Therefore, it is highly marketable as an accessory for small LCD televisions. Furthermore, by combining it with a small video, a very simple educational system can be constructed.

る。If you have an AC adapter for a small TV built into the projector, you won't have to run the small TV on batteries.
By connecting a small TV to an external actuator terminal, it can be used as a projector for hours on end.

Therefore, in that case, it is necessary to turn the small TV upside down so that it can be housed in the projector.
