Description

Can handle the display of universal serial bus data

Technical field

The utility model relates to a kind of display, particularly a kind of display of handling the universal serial bus data.

Background technology

In the middle of computer peripheral equipment product miscellaneous, display as single rifle projector, display etc. occupies indispensable critical role always in the middle of output device, generally speaking, above-mentioned display can be from the image source that the image data of an external signal source (being generally a personal computer) input one analog format (for example NTSC etc. analog format) produces as this display institute desire.Next will be that example illustrates that this display forms the principle of image with a projector.

See also Fig. 1, the functional block diagram of the projector 10 of known technology has been shown among Fig. 1.Projector 10 includes a housing 12; One analogue-to-digital converters (Analog-to-DigitalConverter) 14, be arranged in the housing 12 and the external signal source 16 that is electrically connected on importing the image data of an analog format, analogue-to-digital converters 14 are used for the image data of this analog format is converted to the imaging data (for example digital format of RGB888 or YUV422 etc.) of a digital format; One scale controller (Scaler) 18 is arranged in the housing 12 and is electrically connected on analog-to-digital converter 14 importing the imaging data of this digital format, and scale controller 18 is used for the size of the image that forms according to 10 desires of projector and comes this imaging data of convergent-divergent; One drive circuit 20, be arranged in the housing 12 and be electrically connected on scale controller 18, be used for behind this imaging data of scale controller 18 convergent-divergents producing one and drive signal driving a display plane (Display Panel) 22, and utilize a light source 24 irradiation display planes 22 with the image reflective projection on a display screen (not being shown among Fig. 1).

Please note, aforesaid display can also be a display (Monitor), a LCD for example, the building block that it comprised and the principle of video picture are all similar with projector 100 minutes, but this display also comes this image of reflective projection unlike projector 10 with light source irradiation display plane 22, but the light that directly utilizes a display plane to be sent shows this image.

And having had between in recent years significantly progressively since computer-related technologies, the function of personal computer no longer is confined to document and handles and mathematical operation, and gradually towards multimedia application development.For adapting to this trend, the computer interface equipment that various multimedias are relevant also makes rapid progress.Wherein, as digital image pick-ups such as digital camera, digital cameras, because its powerful and easy to use etc. characteristic has become the popular new lover of consumption.This type of digital image pick-up can be stored in the memory storage (for example a CF card or SD card etc.) wherein taking the form of the image of gained with digital document (for example JPG etc. form) usually; and if store in one computing machine when user's desire is sent to this image data; show or when carrying out further image processing; then can use universal serial bus (Universal Serial Bus usually with this digital image pick-up compatibility; to call USB in the following text) wiring; or it is compatible and use the reader device of USB wiring with this memory storage; be electrically connected to the USB port of this computing machine; this image data be converted to the sequence data that meets the USB specification and transfer to this computing machine, in this computing machine, use an application software that matches with this digital image pick-up (being generally the special software that manufacturer developed of this digital image pick-up) that this sequence data is reduced to this image data simultaneously.

From the above, digital multimedia product such as the image capture unit of the display of single rifle projector etc. and digital camera etc. is instrument powerful, easy to use, is that professional image worker and general popular work are gone up and crucial product in life.Yet, by above-mentioned image data conversion and treatment scheme as can be known, when the display desire of known technology shows by the captured image of a digital image pick-up, after then must be from this digital image pick-up one image data being downloaded to a personal computer by the USB wiring earlier, convert this image data to analog format via this personal computer again, just can transfer to this display to show this image, such process has not only increased the trouble in user's use, and buying more a computing machine in order to reach this purpose has also significantly increased user's unnecessary spending.
