Description
Technical field
The present invention relates to a kind of projection display equipment that image is carried out to projection and demonstration, relate in particular to a kind of projection display equipment that adopts transparent or semitransparent projection screen.
Background technology
Projecting apparatus is a kind of common device that image can be carried out to projection and image is shown to projection screen, and projecting apparatus need to rely on projection screen could show image. Projecting apparatus can be connected with computer, VCD, DVD, BD, game machine, DV etc. by different interfaces and play corresponding vision signal; Projecting apparatus is widely used in family, office, school and public place of entertainment at present.
On market, the projecting apparatus of most of projection display equipments and projection screen are independent separate. Because projecting apparatus and the projection screen of projection display equipment are independent separate, before using so first, need projecting apparatus to projection display equipment and projection screen to carry out installment and debugging and just can use; Install and generally need to adopt the mode such as floor stand, suspention to install, also can be embedded within the walls or the mounting means of exhibition booth. When each transfer projection display equipment, to again reinstall and debug. Projecting apparatus separates with projection screen, and each transferring position all needs installation and debugging just can carry out work, so very complicated on using.
A kind of transparent or semitransparent projection screen occurring again on market in recent years, transparent or semitransparent projection screen has transparent characteristic, in keeping clear video picture, can allow spectators see through projection film and see scenery behind. But due to the distinctive transparent characteristic of this transparent or semitransparent projection screen, when projecting apparatus adopts when rear projection, can see that in positive spectators projecting apparatus directly penetrates, dazzling light, this light is very dazzling, is unfavorable for that spectators watch image.
Summary of the invention
The technical problem to be solved in the present invention is to provide and does not a kind ofly need complicated installation just can use and a kind of projection display equipment that adopts transparent or semitransparent projection screen that projection ray can direct projection spectators eyes.
For solving the problems of the technologies described above, a kind of projection display equipment of the present invention comprises projecting apparatus, projection screen, and projection screen adopts transparent or semitransparent projection screen; Wherein, this projection display equipment also comprises base, and projecting apparatus, projection screen, base connect as one; Projecting apparatus is set to the front projection image to projection screen.
Be provided with base, projecting apparatus, projection screen, base connect as one, and such benefit is that user need not just be installed and can be used like a cork projection display equipment by the complicated mounting means that hangs, inlays, and has improved convenience.

As a kind of improvement of a kind of projection display equipment of the present invention, base can extend to Huo Ce front, projection screen front, and projecting apparatus is connected on the base in Huo Ce front, projection screen front. Such benefit is that the layout of projection display equipment is more succinctly attractive in appearance, more firm.
As another kind of improvement of a kind of projection display equipment of the present invention, projecting apparatus is connected on base indirectly by elongation mechanism; Elongation mechanism is used to projecting apparatus that exercisable projector distance or projection angle are provided. Such benefit is to arrange more neatly the position of projecting apparatus.
As another kind of improvement of a kind of projection display equipment of the present invention, projecting apparatus is connected with the frame of projection screen or projection screen by elongation mechanism; Elongation mechanism is used to projecting apparatus that exercisable projector distance or projection angle are provided. Such benefit is to arrange more neatly the position of projecting apparatus.
As another kind of improvement of a kind of projection display equipment of the present invention, projection screen is connected with base indirectly by connecting entity, and projecting apparatus directly or by elongation mechanism is indirectly connected to and connects entity or base. Projection screen is connected with base indirectly by connecting entity, instead of whole projection screen is connected to the base of ground proximity, and size that like this can reduced projection screen does not affect again actual viewing effect, has reduced cost.
As the further improvement of a kind of projection display equipment of above the present invention, projection screen is erected on base substantially; Further improve, projection screen adopts disobeys keep to the side frame or support and also can keep the hard material of profile to make; Disobeying keep to the side frame or support, also to keep the hard material of profile can be clear glass or transparent plastic sheet. Transparent or semitransparent projection screen can be also line holographic projections film or transparent minute surface projection film; Further improve line holographic projections film or transparent minute surface projection film and clear glass or transparent plastic sheet laminating, composition projection screen. So not only can make spectators obtain and preferably watch visual angle, the aesthetic property also increasing.
