The external mobile phone projection system can enlarge and display the projections of documents, web pages, photographs and video clips stored in a mobile phone, facilitating users to watch the character, photographs or video information on the mobile phone screen. The external mobile phone projection system is widely applicable to education and other fields in need of projectors.
Description
Technical field
The utility model relates to a kind of portable translucent instrument system, relates in particular to a kind of external mobile phone projection system.
Background technology
Projector is a kind of projection arrangement that is used for amplifying display image.Be applied to the meeting room demonstration at present and on giant-screen, watched film by connecting equipment such as DVD player in the family.
At present, the trend of communicating terminal development must be two extreme, greater or lesser.Though though present stage mobile phone screen done very greatly because the limitation of itself structure has been difficult to have broken through again.If can expand to the mode of mobile phone screen-use light projection in the bigger media, we just need not carry PC etc. again when demonstration PPT (lantern slide), the content stores that only needs will wait to explain and publicise or deliver is in mobile phone, on directly can be from the mobile phone projection to the curtain, bring great convenience to people undoubtedly.In addition, the audio/video file in the mobile phone can also be shown projection on bigger screen, bring people better audio visual effect.
The present electric embedded projector of a kind of mobile phone of successfully having developed in Dezhou is exactly as at the built-in projector of the inner built-in camera of mobile phone.There is following problem in this built-in projector: 1, energy consumption issues.This is inevitably, increases new function consumes battery more.Especially be embedded on the mobile phone as this powerful parts of projector, can increase energy consumption greatly.2, heat dissipation problem.According to principle of conservation of energy, in the application of reality, electric energy can not be converted into luminous energy fully, the that part of of luminous energy can not be converted into and heat will be become, but because the narrow internal structure of mobile phone, heat can not distribute at once and finish, and may be absorbed by the miscellaneous part of mobile phone, influences the performance and the serviceable life of mobile phone greatly.Even can be in mobile phone inside at an embedded fan or heat radiator, but because the restriction of mobile phone inner space, the effect of doing like this is certainly not fine.3, industrial design problem.How to do projector as far as possible little, guarantee the problem of comparatively ideal resolution simultaneously.Arrange again that on very thin mobile phone a projector that suitable volume arranged is a difficult problem, in addition, must consider optical configuration.The problems referred to above make and the great challenge that is designed to of Portable mobile phone projector be difficult to accomplish at least under current technical conditions.
The utility model content
The technical problems to be solved in the utility model provides a kind of external mobile phone projection system, solves the deficiency that aspects such as the power consumption of the existing embedded projector of mobile phone and heat radiation exist.
In order to address the above problem, the utility model provides a kind of external mobile phone projection system, comprises mobile phone, video output data line, and portable projector, and described portable projector is provided with continuous decode modulated device and optical projection portion; Described mobile phone comprises storage unit, video output terminals and the data-interface that links to each other successively, and described data-interface links to each other with an end of video output data line, and the other end of described video output data line links to each other with described decode modulated device.
Further, described external mobile phone projection system also can have following characteristics: described data-interface is the VGA interface.
Further, described external mobile phone projection system also can have following characteristics: described portable projector is provided with external power supply.
Further, described external mobile phone projection system also can have following characteristics: described video output terminals is provided with data processing module, and described data processing module links to each other with described data-interface.
Further, described external mobile phone projection system also can have following characteristics: described data processing module also links to each other with display unit on the described cell phone mainboard.
External mobile phone projection of the present utility model system, projection amplifications such as the file that mobile phone EMS memory can be stored up, webpage, photo, video segment show, make the user watch literal, picture or image information on the mobile phone screen more easily, can be widely used in education and other needs the field of projector.
Description of drawings
Fig. 1 is the composition structural representation of external mobile phone projection of the present utility model system;
Fig. 2 is the block diagram of external mobile phone projection system embodiment of the present utility model;
Fig. 3 is the data-interface figure of external mobile phone projection system embodiment of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail:
Referring to Fig. 1 and Fig. 2, external mobile phone projection of the present utility model system comprises: mobile phone 1, video data line 2 and portable projector 3, mobile phone 1 links to each other with portable projector by video data line 2.Mobile phone 1 comprises storage unit, video output terminals and the data-interface that links to each other successively, and portable projector 3 is provided with decode modulated device, optical projection parts, external power supply and heat abstractor (not shown).Wherein, decode modulated device, optical projection parts and heat abstractor all are embedded in the minitype portable projector 3.Wherein:
Storage unit is used for form stored images data messages such as files;
Video output terminals is used for exporting the image data information of memory cell storage to data-interface;
Data-interface links to each other with video data line 2, as the output interface of mobile phone;
The video output data line is used for from data-interface the image data information transmission of mobile phone EMS memory storage to projector.
After portable projector receives the data of video output data line transmission, by the decode modulated device of portable projector described data are carried out decode modulated, then by optical projection parts formation image.
The optical projection parts can use the microminiature projector, develop the embedded microminiature projector that adopts 2 MEMS scanners and LASER Light Source as U.S. Microvision.
Wherein, the data-interface that is provided with on the mobile phone can adopt existing VGA (Video GraphicArray, Video Graphics Array) interface, and the pin figure of the VGA interface of one embodiment of the present of invention as shown in Figure 3.This VGA interface is the trapezoidal plug of 15 pins, is divided into 3 rows, and 5 of every rows are used for transmission of analogue signal.Each stitch is represented respectively among the figure: 11 are red primary, and 12 is green primary, and 13 is blue primary, and 14,24,32 are address code, 15,31,35 be the self-test stitch, 21 is red ground, and 22 is the greenery patches, and 23 is blue ground, 25 for digitally, 33 for row synchronously, 34 is field synchronization.For being fit to the configuration design of mobile phone, also can carry out suitable adjustment, as long as the stitch among the figure is arranged, as being designed to two rows.In the present embodiment,, connect the VGA interface of mobile phone, just can reach the purpose of video output by VGA video output data line.
