Abstract
The utility model relates to a host computer with a projection function, which is at least provided with general configurations such as a central processing unit, a hard disc, a floppy drive, each input and output peripheral interface, etc. The host computer is also provided with an optical projection device provided with a liquid-crystal display panel and a lens convexly exposed out of the host computer. The optical projection device is connected with the central processing unit of the host computer through liquid-crystal projection control circuits. Thus, input and output peripheral devices can be circumscribed to the host computer, and the host computer can be used as a general computer. In addition, the liquid-crystal projection control circuits can be driven by a bus, and video image signals transmitted from a computer are delivered to the liquid-crystal display panel first and then projected to a screen from the lens. Therefore, the host computer can be used as a computer projector.
Description
The utility model relates to a kind of host computer with projecting function, is meant a kind of can the use as computer simultaneously especially, or the host computer of computer-projector machine use, to increase the host computer function, simultaneously, reduces the acquisition cost of computer-projector machine.
General computer-projector machine as shown in Figure 4, it need include a computer 5 (as laptop), a projector 6 and a screen 7.Referring to Fig. 5, wherein computer 5 is connected with projector 6 by video signal line (VGA signal wire) 51, and this projector 6 includes: a high-speed a/d converter 61 is used for high frequency R, G, a-signal that computer 5 transmission are come out are become digital signal; One microprocessor 62 is used for above-mentioned digital signal is handled; One software 63; One short-access storage 64, it is a buffer area, is cached in this short-access storage 64 with digital signal, takes out this digital signal by microprocessor 62, and is sent on the LCD panel; One sequential operation circuit; One optical projection apparatus, it includes a reverberator 661, and light source 662, convex lens 663,664 and a LCD panel 665 etc. are projected to the picture on the LCD panel 665 on the screen 7.
Because this computer-projector machine must comprise a computer 5 and a projector 6, therefore, relatively high on whole acquisition expenses, and its high-speed a/d converter 61 is belonging to high-tech product on the semiconductor technology at present, Taiwan manufacturer still can not make voluntarily, must rely on import, make whole maintenance or change the outfit to be not easy.
The purpose of this utility model provides a kind of host computer with projecting function, when external each the output/input peripheral of this host computer, can be used as general computer uses, because of it also is provided with optical projection apparatus, LCD panel and the protruding outer camera lens of host computer that is exposed to, can also use as the computer-projector machine, thereby increase its function.
The utility model is achieved in that it is provided with a central processing unit, and this central processing unit is connected with the interface of a hard disk, floppy disk, each I/O peripherals respectively, so that connect each peripherals by this interface; It is characterized in that: on host computer, be provided with a crystal projection operation circuit in addition, this crystal projection operation circuit also is connected with central processing unit, and drive the crystal projection operation circuit by central processing unit, this crystal projection operation circuit connects with an optical projection apparatus again, and this optical projection apparatus is embedded with a camera lens on computer host housing.When central processing unit drives the crystal projection operation circuit, make the crystal projection operation circuit pass through optical projection apparatus from the video signal that computer sent out, be incident upon on the screen from camera lens.
Wherein optical projection apparatus is provided with a reverberator, lamp source, first and second convex lens respectively in regular turn, and is provided with a LCD panel between two convex lens.
Characteristics of the present utility model are by a host computer, both can be used as computer and have used, also can be used as the computer-projector machine and use, thus the acquisition expenses of reduction computer-projector machine.
Below in conjunction with drawings and Examples, describe shape of the present utility model in detail, structural attitude and effect.
Fig. 1 is a block scheme of the present utility model;
Fig. 2 is the block scheme of host computer of the present utility model and optical projection apparatus;
