Preferably, said microprocessor adopts the MSP430F2232IRHA baseband chip.
Technical matters of the present invention solves through following further again technical scheme.
Also be provided with direct supply processor controls, start switch and charger circuit, said direct supply processor controls is connected with said charger circuit with said Video Decoder, said DLP, said direct supply, said start switch respectively.
Said charger circuit comprises metal oxide semiconductor field effect tube (MetalOxide Semicoductor Field Effect Transistor; Initialism is MOSFET), battery booster circuit and charging circuit; The control end of said MOSFET is connected with said direct supply processor controls; The output terminal of said MOSFET is connected with said DLP, battery to be charged respectively; System power supply and charge power supply are provided respectively, and the input end of said battery booster circuit is connected with said battery to be charged, and the output terminal of said battery booster circuit is connected with said charging circuit; Said battery booster circuit is controlled the data access port of delivering to direct current 5v input socket and iphone 4 mobile phones after the battery that will be connected input end boosts through switch, offers the iphone cell-phone charging.
The beneficial effect of the present invention and prior art contrast is:
The present invention only is applicable to the iphone4 mobile phone; Can be with composite video signal Projection Display on giant-screen or other surfaces of iphone4 mobile phone reception; And need not to use heavy desktop computer or notebook computer, can also give the iphone4 cell-phone charging and serve as reserve battery.
Description of drawings
Accompanying drawing is that circuit of the present invention is formed block scheme.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the present invention will be described.
A kind of projector like adapted iphone 4 mobile phones shown in the drawings is included in digital micro-mirror assembly and the direct supply that can purchase the market.
Iphone 4 mobile phones comprise the data access port that is arranged on mobile phone body tail end, and microprocessor, transmitter, receiver, LCDs, button, antenna.Microprocessor adopts the MSP430F2232IRHA baseband chip that is provided with 16bit/8bit data-interface and universal input and output port.
Be provided with Video Decoder and monolithic DLP; The input end of Video Decoder is connected with the composite video signal output terminal of iphone 4 mobile phones; The output terminal of Video Decoder is connected with the input end of monolithic DLP, and the output terminal of monolithic DLP is connected through cable with the digital micro-mirror assembly.Video Decoder adopts the TVP5151PBS chip, and DLP is monolithic DLP, adopts the DPP2607 chip.
The RGB lamp that is provided with led drive circuit and drives by led drive circuit, led drive circuit is connected with DLP, and the RGB lamp is connected with said led drive circuit.
Be provided with dynamic storage, dynamic storage is connected with monolithic DLP.
Also be provided with direct supply processor controls, start switch and charger circuit, the direct supply processor controls is connected with charger circuit with Video Decoder, monolithic DLP, direct supply, start switch respectively.
Charger circuit comprises MOSFET, battery booster circuit and charging circuit; The control end of MOSFET is connected with the direct supply processor controls; The output terminal of MOSFET is connected with monolithic DLP, battery to be charged respectively; System power supply and charge power supply are provided respectively, and the input end of battery booster circuit is connected with battery to be charged, and the output terminal of battery booster circuit is connected with charging circuit; The battery booster circuit is controlled the data access port of delivering to direct current 5v input socket and iphone 4 mobile phones after the battery that will be connected input end boosts through mode switch, offers iphone 4 cell-phone chargings.
