Embodiment
The fundamental diagram of a kind of outdoor projection formula of the utility model billboard as shown in Figure 1, a kind of outdoor projection formula of the utility model billboard comprises control module 11, projection screen as advertising panel 1, for to projection screen projected image projection arrangement 12, store the memory module 13 of ad content data, projection arrangement 12, memory module 13 are all connected with control module 11 or couple; Wherein, projection arrangement 12 adopts short Jiao/ultrashort out-of-focus projection instrument.
Short Jiao/ultrashort out-of-focus projection instrument is adjusted the distance and is required less, and often only need the projector distance of tens centimetres, can project out larger picture in shorter distance.Short Jiao/ultrashort out-of-focus projection instrument is also very convenient when installation, only need be placed on projection screen front, compares the conventional projector that usually can only be arranged on centre, roof and has and more save space, the advantage such as easy for installation.At present, on market, short Jiao/ultrashort out-of-focus projection instrument can in the distance of about 1.8 meters, and project 100 cun of even larger pictures, such performance embodies the user demand that can meet little spatial user completely.Projector distance and the ratio of projection size ratio can be adopted to be less than or to equal the projector of ratio of 1:1.
Projector distance and the ratio of projection size ratio can also be adopted to be less than or to equal the short Jiao/ultrashort out-of-focus projection instrument of ratio of 0.8:1.Projector distance and the ratio of projection size ratio can also be adopted to be less than or to equal the short Jiao/ultrashort out-of-focus projection instrument of ratio of 0.5:1.Here " projector distance " refers to the distance of projection arrangement 12 to projection screen, and projection size refers to the full-size of the clear picture that this projector distance projects.Projection arrangement 12 can to adopt in the short Jiao/ultrashort out-of-focus projection instrument such as reflective short Jiao/ultrashort out-of-focus projection instrument, short Jiao of wide-angle lens hair style/ultrashort out-of-focus projection instrument, short Jiao of fish eye lens formula/ultrashort out-of-focus projection instrument any one.Projector can adopt any one projector such as CRT, LCD, DLP, laser.
Reflective short Jiao/ultrashort out-of-focus projection instrument adopts the short distance shadow casting technique of " reflector " formula.The inspiration of the short distance shadow casting technique of " reflector " formula comes from the principle of work of rear-projection display system, can realize larger sized projected picture under shorter light path.The shortest large picture that can project more than 100 inches in one meter of distance.The Technical Architecture of " reflector " formula, in essence and not only change the focal length of projector lens, but also need, by adding one piece of special light path catoptron, to realize the transfer of light path injection angle, and then realize " short Jiao " and " off-axis " two is main greatly function technical characteristic.
Short Jiao of wide-angle lens hair style/ultrashort out-of-focus projection instrument, short Jiao of fish eye lens formula/ultrashort out-of-focus projection instrument adopt more complicated lens design, realize the product technology requirement of large " off-axis " beyond the function realizing short Jiao.The realization of short burnt part depends on wide-angle lens or fish eye lens technology, and the lens wearer that Off-axis sections then depends on particular design realizes.
Memory module 13 can adopt flash memory (Flash Memory) storer, hard disk etc., hard disk can adopt solid state hard disc (Solid State Drives, SSD), mechanical hard disk (HDD conventional hard), hybrid hard disk (the new hard disk that HHD mono-piece is born out based on traditional mechanical hard disk) etc.SSD adopts flash memory particle to store, and HDD adopts magnetic video disc to store, and hybrid hard disk (HHD:Hybrid Hard Disk) is a kind of hard disk that magnetic hard-disk and flash memory are integrated together.Control module 11 can be utilized to complete the configuration of the list creating of advertisement play content, the maintenance of play content and play parameter, control module 11 pairs of advertisement play content can also be utilized to decode.Memory module 13 may be used for storing advertisement play content and play parameter.Processor can be adopted as control module 11, and processor comprises the chip of the types such as central processing unit, microprocessor, microcontroller; Certainly, the device such as unit sheet or powerful robot calculator main frame also can be adopted to provide the function of control module 11.Also can digital signal processor be set, such as, can sends instruction by microcontroller to data-signal process chip, make it process vision signal exactly, and the signal handled well is sent to projection arrangement 12 plays.
