Description
Technical field
The present invention relates to a kind of projector with touch projection screen.
Background technology
Along with movable day by day frequent such as commercial affairs, exhibitions, demonstration and audio-visual education programme, screen prjection technology has become the multimedia show means of people's indispensability, and in the every field such as business office, scientific research, education and instruction, army's training and sector application, screen prjection technology is widely used.
In the market common high resolving power display system have two kinds dissimilar, a kind of is optical projection system, also referred to as projector; Another is display screen system, is mainly LCD display screen and LED display screen.The advantage of projector be moderate, movability is good, and along with the development of technology, its volume is also constantly reducing.Generally projector and projection screen are separate types, and this gives to carry and brings inconvenience; Projection screen is general does not in addition have the function of input equipment only as real use, and projector can only project information or image on projection screen, the information on screen cannot be fed back in computing machine, therefore also just cannot carry out human-computer interaction.
Summary of the invention
Technical matters to be solved by this invention is for the deficiencies in the prior art, and a kind of projector with touch projection screen is provided, and it is simple in structure, be easy to carry, cost is lower, and projection screen can input information, realizes the interactive operation of optical projection system.
The present invention is for solving the problems of the technologies described above by the following technical solutions
With a projector for touch projection screen, the projection screen with touch sensitive layer that comprises projector and be attached thereto; Between described projector and projection screen, be provided with support, for fixing and support projection curtain, described projection screen comprises touch-control module, touch-control locating module and power module, and described support is provided with turning axle, for regulating angle between projection screen and projector.
Preferably, described projector comprises mixed-media network modules mixed-media, embedded processing unit, projection module, audio-frequency module, screen capture/playing module; Described audio-frequency module, mixed-media network modules mixed-media, screen capture/playing module and the projection module of playing for audio collection is connected to embedded processing unit.
Preferably, the touch sensitive layer of described projection screen is connected with the embedded processing unit in projector with signal wire by power lead.
Preferably, described audio collection module is microphone.
Preferably, described audio playing module is loudspeaker.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
1,simple in structure, be easy to carry, cost is low; This utility model is integrated by projector and projection screen,
2,realize the input information of projection screen, realize the interactive operation of optical projection system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model projection screen schematic diagram.
In figure, 1-projector 2-projection screen 3-camera lens 4-turning axle 5-support.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
With a projector for touch projection screen, the projection screen with touch sensitive layer that comprises projector and be attached thereto; Between described projector and projection screen, be provided with support, for fixing and support projection curtain, described projection screen comprises touch-control module, touch-control locating module and power module, and described support is provided with turning axle, for regulating angle between projection screen and projector.
Described projector comprises mixed-media network modules mixed-media, embedded processing unit, projection module, audio-frequency module (audio collection can be used microphone, and audio frequency is play can use loudspeaker), screen capture/playing module; Described audio-frequency module, mixed-media network modules mixed-media, screen capture/playing module and the projection module of playing for audio collection is connected to embedded processing unit.The touch sensitive layer of described projection screen is connected with the embedded processing unit in projector with signal wire by power lead.
As shown in Figure 1, small-sized projection screen is placed in to the projector with curtain of bottom (or top) composition of projector
Whole projection is often divided into two-layer, conventional projector layer and curtain layer; Curtain is placed on projector bottom or top, can extract out to be placed in projector the place ahead and to use as projection screen while needing, and has curtain fixed support on projector, curtain layer can be propped up and is fixed.On support, there is turning axle, can regulate the angle between projection screen and projector; Curtain layer is coated with touch sensitive layer, by power lead, is connected with the embedded system in projector with signal wire; In projector, there is the touch-control module of supporting touch control film;
The touch-control positioning system that has projection support touch-control location in projector; User operates the embedded system of projector inside by touch projection curtain.
As shown in Figure 2, there is touch control film power control system projector inside, when projection screen is not extracted out, closes the power supply of projection touch control film, opening power when extracting out, and receive signal; The inner embedded system of projector is supported touch control operation, and inside has touch-control module to process the touch-control input signal of projection screen; The inner embedded system of projector need to realize projection screen touch-control positioning function, when projection screen and projector form different angles, the projected image obtaining can be different, for different figures, touch-control positioning system will be processed, and for user's touch control operation, locates accurately.
