Description
Technical field
The present invention relates to a kind of monitor keyboard system and display methods.
Background technique
Current keyboard and display is unable to Direct Communication, and keyboard could communicate after only passing through host with display, this
Sample cannot meet the needs of certain fields well.Such as in medical field, need to carry out regular cleaning disinfection, mesh to keyboard
Before be to be monitored by host to keyboard, keyboard is all at least pressed and once then thinks that completing wiping to keyboard disappears
Poison after the completion of host recognizes keyboard cleaning disinfection, then sends display for the signal of completion and shows.But it is big at present
Part host is in open state, it is easy to artificially operated on host, so that substantive disinfection is not carried out to keyboard, this
Sample just gives subsequent operator to leave security risk.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide, a kind of structure is simple, uses
Effect is good, and is able to achieve the monitor keyboard system and display methods of keyboard and display Direct Communication.
The technical scheme adopted by the invention is that: a kind of monitor keyboard system includes mainboard, power panel, display screen
And keyboard, be provided with the first display interface and keyboard interface on the mainboard, the power panel and the display screen with it is described
Mainboard is connected, and OSD chip and display control module are provided on the mainboard, and the keyboard passes through the keyboard interface and institute
It states OSD chip to be communicated, the OSD chip is communicated with the display control module, and the display control module is by institute
It is exported after stating the signal of OSD chip and the signal synthesis of first display interface to the display screen.
Further, the keyboard interface is with the one or more of lower interface: serial interface, PS/2 interface, USB interface.
Further, first display interface is with the one or more of lower interface: HDMI interface, DVI interface, VGA connect
Mouthful.
The beneficial effects of the present invention are: the present invention includes mainboard, power supply since the present invention uses the design of keyboard interface
Plate, display screen and keyboard are provided with the first display interface and keyboard interface, the power panel and the display screen on the mainboard
It is connected with the mainboard, the keyboard is connected by the keyboard interface with the mainboard, so, structure of the invention letter
List, using effect are good, without can be achieved with keyboard and display Direct Communication by host.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
In the present embodiment, a kind of monitor keyboard system includes mainboard 1, power panel 2, display screen 3 and keyboard 4,
Be provided with the first display interface 5 and keyboard interface 6 on the mainboard 1, the power panel 2 and the display screen 3 with the master
Plate 1 is connected, and OSD chip 7 and display control module 8 are provided on the mainboard 1, and the keyboard 4 passes through the keyboard interface 6
It is communicated with the OSD chip 7, the OSD chip 7 is communicated with the display control module 8, the display control mould
Block 8 will export after the signal of the OSD chip 7 and the synthesis of the signal of first display interface 5 to the display screen 3.It is described
The model of OSD chip 7 has MAX7456, OSD7556, OSD7516, UPD6465, MB90092.
In the present embodiment, the keyboard interface 6 be with the one or more of lower interface: serial interface, PS/2 interface,
USB interface.
In the present embodiment, first display interface 5 is with the one or more of lower interface: HDMI interface, DVI connect
Mouth, USB interface.
The display methods includes the following steps:
A1, the keyboard 4 are communicated by the keyboard interface 6 with the OSD chip 7；
A2, the OSD chip 7 and the display control module 8 are communicated；
A3, the display control module 8 synthesize the signal of the OSD chip 7 and the signal of first display interface 5 backward
The display screen 3 exports.
The configuration of the present invention is simple, using effect are good, without can be achieved with keyboard and display Direct Communication by host.From
And it is able to satisfy some particular requirements of special dimension.
The present invention is applied to the technical field of monitor keyboard system.
Although the embodiment of the present invention is described with practical solution, the limit to meaning of the present invention is not constituted
It makes, for those skilled in the art, is all to the modification of its embodiment and with the combination of other schemes according to this specification
