Background technique
The projection arrangement is being widely used in commercial advertisement, business presentations manuscript, scientific seminar, merchandise display, drilling
Say the ancillary equipment presented in the occasions such as .. as image.Relevant text and image are incident upon one by the projection arrangement
On cloth curtain.Traditional projection arrangement is to cooperate transparent contribution (transparency) by the text on the transparent contribution using optical principle
And image is projected by the optical projection lens of the projection arrangement.
However, when using projector, still needing to expend many preparation (such as production transparency, preparation in advance
Text file prepares pattern file, printer printing, transparency photocopy ... etc.), and need to additionally purchase a projector.Therefore
When in use, still there are many inconveniences.Furthermore traditional projector is only capable of providing the projection of image, can not provide sound
Playing function, therefore in items displaying, PowerPoint, still there is its shortcoming.
Although making digital projection arrangement and projection dress with better function by means of the progress of digital technology recently
It sets gradually instead of conventional projection device.But the digital projection arrangement still needs to be connected to computer dress through connection cable
Set, can computer generate image be projected on cloth curtain.Also that is, user still needs to other than purchasing computer, additionally
A digital projection arrangement is purchased, the connection for being attached cable is also being needed using preceding, can will be intended in computer installation
The image frame of projection is sent in projection arrangement, is finally projected to image far by the optical projection lens of the projection arrangement
Fang Kuanguang screen.Therefore, actual in use, user is often limited to the yoke of the cable, user is also required
Computer installation and projection arrangement could be linked by being ready to the cable, and can not make the use of immediacy and convenience.
Summary of the invention
The main purpose of the present invention is to provide a kind of projection type computer displaying device, the projection Computer displays
Device combines the projection type computer displaying device of a desktop PC or laptop and image projecting machine function,
By produced by computer installation text or image data it directly can be projected to a projection display screen.
Projection type computer displaying device of the present invention can be connected to a computer installation by a display interfaces, comprising:
One projection display screen configures in the projecting display；One projection lens configures inside the projecting display,
And correspond to the projection display screen；One reception video signal and be converted into optical signalling and transmit optical projection dress
It sets.
Present invention incorporates the functions of computer installation and projecting display, and reach computer image and be able to directly
It connects and shows text or figure and picture signal in a manner of projection, calculating can be reached under the situation for being not required to additionally configure projector
The function of machine and image projecting.

Specific embodiment
Refering to Figure 1, being incorporated into a desktop PC device 1 for projection type computer displaying device 2 of the present invention
When perspective view.As shown, when the configuration of projection type computer displaying device 2 of the invention is connected to computer installation 1, it can
The display device for directly replacing former computer installation 1, when being shown using the man-machine display interface as operator or as image
Projection arrangement.
Fig. 2 is perspective view when projection type computer displaying device 2 of the present invention is incorporated into a notebook computer device 3,
In this application examples, signal connection type and operating principle are all identical as previous application examples, but in user, can more play height
Portable advantage, more suitable for the use of the occasions such as commercial exhibition, speech, explanation meeting.
Fig. 3 is the simplification circuit diagram that projection type computer displaying device 2 of the invention is connect with computer installation 1.
It mainly include central processing unit 10 in the computer installation 1 of the simplification, system bus 11, PCI/ISA bus 12, random
The existing elements such as access memory 13, read-only memory 14, bridge 15, key board unit 16, data storage device 17.
Belong to color monitor circle in the display interfaces 20 that current personal computer and laptop generally use
Face is connected to the bus 12 (such as PCI or isa bus) of the computer installation 1.Projection Computer display of the invention
Device 2 can pass through the display interfaces 20 and receive and show video signal caused by the computer installation 1.
Fig. 4 is the further circuit block diagram of projection type computer displaying device 2 and display interfaces 20 in Fig. 3.This is aobvious
Show device interface 20 be include display memory 201, video signal mapping of a set onto another buffer 202 (Mapping Table Register),
Digital analog converter 203 (D/A Converter).
The video signal data as caused by computer installation 1 can be by the data line (Data by PCI/ISA bus 12
Bus it) send into display memory 201.Data in the display memory 201 can be passed in a manner of direct mapping of a set onto another or indirect mapping of a set onto another
It send to projection type computer displaying device 2, such as in the indirect mapping of a set onto another mode shown in schema, it is defeated in the display memory 201
Out signal data as mapping of a set onto another table (Mapping Table) in video signal mapping of a set onto another buffer 202 pointer, with from mapping of a set onto another table
