Abstract
The utility model discloses a projection screen, which comprises a soft screen and a soft screen supporting framework. The soft screen is installed in the soft screen framework by a joint component in a tension way. The surface of the soft screen is provided with a rigidity transparent medium plate, wherein the rigidity transparent medium plate is fixed on the supporting framework. Because the surface of the soft screen is provided with the rigidity transparent medium plate, stability of the back projection soft screen can be obviously enhanced and the drifting condition of the soft screen can be eliminated. Moreover, the rigidity transparent medium plate can prevent the surface of the screen from deforming so as to project the integral and clear image.
Description
Technical field
The utility model relates to a kind of projection screen that is applicable to large screen display.
Background technology
The screen of existing large screen projection product generally is divided into soft curtain and two kinds on hard curtain, the base material of hard curtain generally is glass or organic material, reason owing to aspects such as basic material and transportations, it is very big that the size of hard curtain generally can not be done, moreover organic material is affected by environment distortion can to occur, causes the screen surface out-of-flatness.Although soft curtain can be done very greatly and easy transportation, the soft curtain of large scale then can be subjected to airflow influence drift of a certain amount of front and back or shake to occur, and therefore picture will occur defocusing and fog.Particularly in the technology of many projector's lap splice projections, the drift of this screen also can bring picture the situation of separating to occur.
The utility model content
The purpose of this utility model provides a kind of large-size screen monitors projection screen that can eliminate drift or shake.
Above-mentioned purpose can realize by following technical scheme: comprise soft curtain and soft curtain support frame, soft curtain is tightened through web member and is installed in the support frame, be close to or near the surface of soft curtain one rigidity transparent medium plate be set, this transparent medium plate is fixed on the supporting seat.
Described rigidity transparent medium plate can be glass or organic glass.
Described rigidity transparent medium plate can be the plane, also can be curved surface.
Described rigidity transparent medium plate surface can be covered with the film that can reduce the light reflection.
Described rigidity transparent medium plate can be single monoblock, also can be spliced by an above transparent medium plate.
Soft curtain of described projection and rigidity transparent medium plate can separately fix support, also fixed support together.
Because the surface at soft curtain is provided with rigidity transparent medium plate, can obviously improve the stability of the soft curtain of projection, prevent the drift and the shake of soft curtain, the separation of images that elimination causes thus and fuzzy has improved convenient transportation under the prerequisite that keeps drop shadow effect.
Description of drawings
Fig. 1 is the utility model use principle synoptic diagram;
Fig. 2 is the partial structurtes enlarged drawing at D place among Fig. 1.
Embodiment
As shown in Figure 1, the projection source a b that emits beam throws into large screen back projection shadow screen c and goes up displayed image.As shown in Figure 2, projection screen comprises soft curtain 4 and soft curtain support frame 1, and soft curtain 4 is tightened through web member 2 and is installed in the soft curtain support frame 1, in a wherein side of soft scene plot face, be close to the mounted on surface one rigidity transparent medium plate 3 of soft curtain 4, this transparent medium plate is fixed on the supporting seat; Transparent medium plate 3 also can be installed in the opposite side of soft scene plot face; This rigidity transparent medium plate can be glass or organic glass.The soft curtain of back projection can be close to the transparent medium plate, and together on the fixed support framework; Soft curtain has certain interval in the middle of with the transparent medium plate also can being, generally below 10cm, soft like this curtain and transparent medium plate then can separate fixed support in the gap.
Above-mentioned rigidity transparent medium plate can be the plane, also can be curved surface.Can apply or be coated with one deck on transparent medium plate surface and can reduce the film that light reflects, the loss when seeing through to reduce light.The transparent medium plate can use a monoblock, also can be spliced by two or more than two.Throw the installation of soft curtain before the utility model also can be used for,, guarantee the clear of projected image in order to eliminate the shake and the drift of soft curtain.
Claims (5)
