Problems solved by technology
However, the existing projection TV integrates the casing and the optical image device into an immutable fixed structure, and the volume of the casing is proportional to the image size that can be presented, which will make the overall projection TV volume It tends to be bulky, not only difficult to transport, but also takes up a considerable amount of indoor space when not in use
[0005] Furthermore, although the current plasma TV or traditional cathode ray tube (CRT) TV can also increase its size to achieve a large-screen image performance effect, if the size of the image exceeds 40 inches, the overall plasma TV Or the traditional cathode ray tube (CRT) will be more bulky, and the cost is also quite expensive, which is not acceptable to ordinary families

The invention relates to a projection TV which is formed by a foldable housing and a projector monomer. Wherein, the housing has at least one detachable projection screen and one loudspeaker while a container which can be foldable closed and pulled is mounted at its back; the container is used as the arrangement space of said projection monomer and the relative optical elements to form a dual-purpose TV set which is the back projection type that mounting the projection monomer inside the housing or the front projection type that mounting the projection monomer outside the housing, while the housing is foldable for easy conveyed and stored.
Description
technical field [0001] The present invention relates to the improvement of the unit structure of the projection TV, and aims to provide a dual-purpose projection TV that can project images from the inside of the casing to the back of the projection display screen, or project images from the outside of the casing to the front of the projection display screen; especially , the casing can be folded and closed to facilitate the handling and storage of the projection TV. Background technique [0002] According to the general application of front projection (FP) audio-visual equipment seen in conference rooms or home theaters, the video signal is mainly connected to a projector (or projector), and the projector converts the video signal into an optical projection image, and The image projected by the projector is displayed on a display screen outside a certain distance, so as to achieve the image performance effect of a large screen by utilizing the magnification effect of the opt...
