Description
Technical field
The utility model relates to a kind of projection display equipment projecting to image and show, and particularly relates to a kind of projection display equipment adopting transparent or semitransparent projection screen.
Background technology
Projector a kind ofly common image can be carried out projecting and image is shown to the device of projection screen, and projector needs to rely on projection screen to show image.Projector can be connected with computing machine, VCD, DVD, BD, game machine, DV etc. by different interfaces and to play corresponding vision signal; Projector is widely used in family, office, school and public place of entertainment at present.
On market, the projector of most of projection display equipment and projection screen are independent separate.Because the projector of projection display equipment and projection screen are independent separate, need before using so first that installment and debugging is carried out to the projector of projection display equipment and projection screen 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.To again reinstall and debug during each transfer projection display equipment.Projector is separated 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 in recent years market occurred again, transparent or semitransparent projection screen has transparent characteristic, while the clear video picture of maintenance, spectators can be allowed to see scenery behind through projection film.But due to the distinctive transparent characteristic of this transparent or semitransparent projection screen, when projector adopts rear projection, the spectators being in front can see that projector directly penetrates, dazzling light, and this light is very dazzling, is unfavorable for that spectators watch image.
Summary of the invention
The technical problems to be solved in the utility model is to provide and does not a kind ofly need complicated installation just can use and projection ray can not a kind of projection display equipment adopting transparent or semitransparent projection screen of direct projection spectators eyes.
For solving the problems of the technologies described above, a kind of projection display equipment of the utility model comprises projector, projection screen, and projection screen adopts transparent or semitransparent projection screen; Wherein, this projection display equipment also comprises base, and projector, projection screen, base connect as one; Projector is set to the front projection image to projection screen.
Be provided with base, projector, projection screen, base connect as one, such benefit be user need not by hanging, the complicated mounting means inlayed carry out installation and just can use projection display equipment like a cork, improves convenience.Projector is set to the front projection image to projection screen, when would not see when spectators stand in the front of projection screen that dazzling, the dazzling light that projector directly penetrates, spectators watch image, eyes can be very comfortable.
Improve as a kind of projection display equipment one of the utility model, base can extend to projection screen front or front, side, and projector is connected on the base in projection screen front or front, side.Such benefit is that the layout of projection display equipment is more succinctly attractive in appearance, more firm.
Improve as a kind of projection display equipment another kind of the utility model, projector is connected on base indirectly by elongation mechanism; Elongation mechanism is used for providing exercisable projector distance or projection angle for projector.Such benefit to arrange the position of projector more neatly.
Improve as a kind of projection display equipment another kind of the utility model, projector is connected by the frame of elongation mechanism with projection screen or projection screen; Elongation mechanism is used for providing exercisable projector distance or projection angle for projector.Such benefit to arrange the position of projector more neatly.
Improve as a kind of projection display equipment of the utility model is another kind of, projection screen is connected with base indirectly by connecting entity, and projector directly or by elongation mechanism is connected to connection entity or base indirectly.Projection screen is connected with base indirectly by connecting entity, instead of whole projection screen is connected to the base of ground proximity, the size of reduced projection screen can not affect again the viewing effect of reality like this, reduces cost.
As the further improvement of a kind of projection display equipment of above the utility model, projection screen is erected on base substantially; Further improve, projection screen adopts disobeys keep to the side frame or support the hard material of profile also can be kept to make; Disobeying keep to the side frame or support also can keep the hard material of profile can be clear glass or transparent plastic sheet.Transparent or semitransparent projection screen also can be 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 are fitted, composition projection screen.Spectators so not only can be made to obtain and preferably to watch visual angle, the aesthetic property also increased.
