Abstract
The utility model discloses a computer projector with an SID (Serial Digital Interface). A projection display part comprises a DMD (Digital Mirror Device) control module, a DMD driving module, an optical lens, an LED (Light-Emitting Diode) driving module and an LED light source, wherein a central processor is arranged on a PCB (Printed Circuited Board) of a computer part, and is connected with an SD (Secure Digital) card slot, a USB (Universal Serial Bus) interface, an audio output interface, a VGA (Video Graphic Array) input interface, an HDMI (High-Definition Multimedia Interface) input interface, an AV (Audio-Video) input interface, a flash memory module, a WIFI (Wireless Fidelity) network module, an internal memory module, a mouse control module and a video format conversion module. The computer projector is characterized in that: an SDI (Serial Digital Interface) is formed on a flexible PCB, and is connected with the central processor. Due to the adoption of the computer projector, integration of the SDI interface, a display projection part and the computer part is realized; in particular, the SDI is formed on the PCB, so that receiving of professional digital video-audio signals is realized; and the computer projector with the SDI has high compatibility and high transmission information amount, is small in size, and is low in cost.
Description
Technical field
The utility model belongs to projection arrangement, relates in particular to the computer-projector appearance with SDI interface.
Background technology
In order to adapt to and satisfy the demand of society, at meeting speech, research and teaching; Commercial activity in the home entertaining, is made as the center with computer; Projector is as screen display, and both are designed to one for it, has both computer function when can realize the Presentation Function of projector; The multimedia equipment that is equivalent to the giant-screen portable computer of an internal battery is used socially, and its defective is: the said equipment does not have the SDI interface; Professional digital video-audio signal can not be received, the many-sided requirement of information age today can not be satisfied, its poor compatibility.
Summary of the invention
The purpose of the utility model development provides a kind of computer-projector appearance with the SDI interface, can solve integrated Dian Nao Gong Neng ﹑ and show Gong Neng ﹑ and a kind of computer-projector appearance with the SDI interface that receives digital video-audio signal and one.
The utility model is realized through following step; See accompanying drawing 1; Wherein Projection Display comprises that partly DMD control control module ﹑ DMD drives mould piece ﹑ light and learns mirror head ﹑ LED driving mould piece ﹑ led light source; On the pcb board of computer part central processing unit is installed; It is inserted groove ﹑ USB with the SD card and connects a mouthful ﹑ sound and frequently fail out and meet a mouthful ﹑ VGA and fail into meeting a mouthful ﹑ HDMI and fail into meeting a mouthful ﹑ AV and fail into meeting mouthful ﹑ and dodge and deposit that storing module ﹑ mouse control mould piece ﹑ video format conversion module is connected in the mould piece ﹑ WIFI net network mould piece ﹑; Computer part and Projection Display partly adopt the flexible PCB plate to be connected in one, and it is characterized in that: the SDI interface is housed on the flexible PCB plate, and its interface is connected with central processing unit.
Adopt lithium ion battery or external direct current power supply input power supply, the two has the power supply handover module of handoff functionality changes, and the direct supply input can be to lithium ion cell charging.
Miniature radiator fan is housed in the casing.
Advantage of the utility model and good effect: (1) the utility model is to be one with the Projection Display Bu Fen ﹑ computer of projector part and SDI Interface design; Have both computer function when can realize the Presentation Function of projector; Particularly the utility model is equipped with the SDI interface on pcb board; Having realized receiving professional digital video-audio signal, is a kind of computer-projector appearance with the SDI interface that a kind of compatible Gao ﹑ transmission contains much information; (2) the utility model is a kind of computer-projector appearance with the SDI interface, and its design volume is small and exquisite to be 140 * 91 * 25mm, but adopts all operate as normal of lithium ion battery or external direct current power supply power supply, and cheap.
Description of drawings
Fig. 1 is a kind of circuit structure block diagram of the computer-projector appearance with the SDI interface.
Embodiment
In order to realize that the utility model combines accompanying drawing to do and further describes; See accompanying drawing 1; Wherein Projection Display comprises that partly DMD control control module ﹑ DMD drives mould piece ﹑ light and learns mirror head ﹑ LED driving mould piece ﹑ led light source; On the pcb board of computer part central processing unit is installed; It is inserted groove ﹑ USB with the SD card and connects a mouthful ﹑ sound and frequently fail out and meet a mouthful ﹑ VGA and fail into meeting a mouthful ﹑ HDMI and fail into meeting a mouthful ﹑ AV and fail into meeting mouthful ﹑ and dodge and deposit that storing module ﹑ mouse control mould piece ﹑ video format conversion module is connected in the mould piece ﹑ WIFI net network mould piece ﹑; Computer part and Projection Display partly adopt the flexible PCB plate to be connected in one, and it is characterized in that: the SDI interface is housed on the flexible PCB plate, and its interface is connected with central processing unit.This interface is the interface that receives the digital video-audio signal specially.Adopt lithium ion battery or external direct current power supply input power supply, the two has the power supply handover module of handoff functionality changes, and the direct supply input can be to lithium ion cell charging.Miniature radiator fan is housed in the casing.
Described central processing unit is the TCC890XARM11 computer chip; In order to adapt to more requirement; On the pcb board of computer part, be provided with SD card slot and central processing unit and connect and connect ﹑ USB interface and central processing unit and connect and connect ﹑ SDI interface and central processing unit and connect and connect ﹑ audio output interface and central processing unit and connect and connect ﹑ VGA input interface and central processing unit and connect and connect ﹑ HDMI input interface and central processing unit and even connect ﹑ AV input interface and central processing unit and even connect ﹑ flash memory module and central processing unit and even connect ﹑ WIFI mixed-media network modules mixed-media and central processing unit and even connect the ﹑ memory modules and even connect ﹑ mouse control module with central processing unit and be connected with central processing unit, said projector is provided with that the power supply handover module is connected on lithium ion battery and the pcb board.Central processing unit uses the TCC890XARM11 processor; Inserting groove ﹑ USB with described SD card meets a mouthful ﹑ SDI and connects a mouthful ﹑ sound and frequently fail out and meet a mouthful ﹑ VGA and fail and meet a mouthful ﹑ HDMI and fail and meet a mouthful ﹑ AV and fail and meet mouthful ﹑ and dodge and deposit in the mould piece ﹑ WIFI net network mould piece ﹑ storing module ﹑ mouse control mould piece ﹑ and be connected and controlled by central processing unit; The vision signal of output is connected with RTD2662 video format conversion module; Support the input of HDMI ﹑ VGA ﹑ AV signal simultaneously; Through the decoded form of video format conversion module RT2662 is the RGB888 form; This form is the form of DMD driver module requirement, thereby can the vision signal of this form be sent to the Projection Display part through the flexible PCB plate, projects in the screen at last.The utility model can realize that reception SDI specialty digital video-audio signal also has a kind of can the transmission that shows Gong Neng ﹑ computer function simultaneously and contains much information the computer-projector appearance of the band SDI interface that compatibility is high.
