Abstract

A projector having computer function, the characteristics are that, other than the projecting display unit of the traditional projector, the projector also includes a personal computer mainboard, a hard disk drive storing an operating system, application softwares and data files of different formats, an optical driver for reading data of JPEG, MPEG, DVD, HD-DVD, EVD formats and each part is mounted in the same machine case to compose an integrated projector. After connecting a keyboard and a mouse, the projector can directly use various computer softwares storing on the hard disk, but without in addition connecting the computer to make, edit, store, demonstrate and play files and manuscripts, and greatly convenient for carrying projector to show and demonstrate outside for movements. The projector can quickly increase radio network, bluetooth and radio modem card and so on options, thereby quickly extending or updating function of the projector, and increasing applicability and flexibility of the projector.

Description

Projector with computer function

Technical field

The utility model device relates to a kind of projector, is a kind of projector with computer function.

Background technology

Projector has been widely used in activities such as exhibition, displaying, meeting and teaching, with one independently desk-top computer or independently portable computer and projector link, and the literal in the computing machine, data and image are sent to projector carry out Projection Display, be projector's main and modal usage at present.

This using method has following inconvenience: two overlap separately, and separate equipment has taken bigger space, owing to be furnished with independently power supply, cabinet and extranal packing box separately, so weight is also bigger.Not only inconvenience but also uneconomical under the situation of out using; Need connecting line and power lead separately between two equipment, use also need carry out certain installation before and program is provided with work, wastes time and energy, and makes mistakes easily; Limit by the device signal driving force, the connecting line length between projector and the computing machine is lacked (being generally 1 meter or 1.5 meters), therefore, has also limited the distance between projector installation site and the user, has caused inconvenience for the use of projector.

Other inconvenience also has: existing projector removes the minority kind and has the directly function of reading section kind memory card contents, other has part projector to possess the function that receives the wireless image data, but most of projector does not possess these functions, can not in projector, carry out function corresponding and expand as required.Because the develop rapidly of electronic technology, the appearance of new technology and new product emerges in an endless stream, and does not have the projector of expansion capacity to bring very big inconvenience for the user buys projector's new function of later increase.

When projector is used for exhibition and show activity; generally; visit and exhibitor staff are a lot; no matter use desk-top computer or portable computer; often have and visit the people and consciously or unconsciously computing machine is operated, browse interior in computing machine software in perhaps using a computer by keyboard and mouse.So not only disturb exhibition and show activity, also the safety of computer system has been brought hidden danger.

The utility model content

The purpose of this utility model provides a kind of incorporate, projection display equipment with computer function, it has comprised: the motherboard circuit of personal computer, central processing unit, random access memory circuit module, CD drive, hard disk drive and run on computer operating system software and application software on the harddisk memory, it has also comprised connected projection part, and, more than all parts all be installed in the cabinet.

Computer motherboard circuit in this device has special-purpose figure, image processor and display interface device (VGA), sound treatment circuit and sound IO interface, network controller and network interface (RJ45), series bus controller and RS232 and USB2.0 interface, Magnetic Disk Controller and IDE thereof and SATA interface, PS/2 mouse and keyboard interface, pci bus expansion slot and ATX power interface.

This device need not to connect outer computer can move operation system of computer software and application software.The system software that runs on this device is meant that Microsoft is widely used in the WINDOWS ME of PC, and WINDOWS 98, and WINDOWS 2000, WINDOWS XP, WINDOWS VISTA and WINDOWS XP EMBEDED.The application software that runs on this device is meant the OFFICE that moves down based on above operating system environment, MEDIA PLAYER, REAL PLAYER, PHOTOSHOP, ADOBE PDF READER, application software such as INTERNET EXPLORER and DVD PLAYER.

Projection part in this device is meant the device with Projection Display function that adopts digit optical to handle (DLP) technology or liquid crystal (LCD) or the manufacturing of liquid crystal on silicon reflection (LCOS) technology, and these display device are by high-pressure sodium lamp (UHP) or light emitting diode (LED) light illumination.

The extended capability of this device is embodied in, utilize pci bus expansion slot or USB interface, can increase bluetooth (BLUETOOTH), IEEE802.11b, 802.11g, 802.11a wireless network plug-in card, GSM, CDMA, TD-SCDMA, CDMA2000 and WCDMA radio modem plug-in card and SD, thus MMC card reader plug-in card is finished the function corresponding expansion.

This device can overcome multiple inconvenience and the shortcoming in the aforementioned projector applications, therefore, has significantly improved the comfort level that projector uses, and has also expanded the scope of application of projector and the dirigibility of use simultaneously.

In order to understand content of the present utility model better,, embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.

Description of drawings

Fig. 1 is the block schematic diagram of each ingredient of the utility model.

Fig. 2 uses the utility model imagination to make up, and has expanded the embodiment block schematic diagram of the projector of Bluetooth function.

Embodiment

Fig. 2 is one and makes up according to the utility model conception, has the computer software functipnal capability, and expanded the embodiment of the projector block schematic diagram of Bluetooth function.

This projector is made of 4 major parts:

1. CD drive is used for reading the data of storing on the CD media, its with this device in 4---the 4PC mainboard is connected with ide interface.And the form of CD media is one of following: JPEG, MPEG, VCD, DVD, EVD, HD-DVD, the file and the data of NTFS and FAT32 form;

2. projection display equipment, it is so that 4 in vision cable and this device---the VGA interface of PC mainboard is connected.Be used for showing the vision signal of computing machine output.This projection display equipment adopts digit optical to handle (DLP) technology, and uses ultrahigh pressure mercury lamp (UHP) as lighting source.

3. hard disk drive, it uses ide interface to be connected with the PC mainboard (4) of native system.This hard disk drive is file and the data that are used for software such as the system software WINDOWS XP of storage computation machine and the PDF READER of POWER POINT among the application software OFFICE and ADOBE company and generated by these softwares;
