Detailed description of the invention
Of the present utility model advantage is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Refering to Fig. 2, in this utility model one preferred embodiment, motherboard 30 is arranged in smart machine, which is provided with core
Chip module 40 and interface module 50, chip assembly 40, as the parts of decision motherboard 30 almost all function, sends and receives
Control signal, interface module 50 is connected with chip assembly 40, to set up the data channel transmitting display picture.Meanwhile, interface group
Part 50 can an external display device 60, same foundation with display device 60 transmits the data channel showing picture so that chipset
The picture signal that part 40 is sent by interface module 50 receiving and displaying device 60.As generally described above, display device 60 is led to
Cross interface module 50 and chip assembly 40 is set up when showing image data channel 53, also will send hot plug detection signal 51 and show
Showing device 60 information data is to chip assembly 40, to inform the plugging condition of chip assembly 40 exterior display device 60 and required
Display configuration.And in the present embodiment, in motherboard 30, it being provided with signal imitation module 10 and information storage module, external display fills
Putting 60 when being connected with interface module 50, interface module 50 no longer receives hot plug detection signal 51 and display device 60 Information Number
According to, and by signal imitation module 10 and information storage module simulation and offer.Specifically:
-signal imitation module 10 electrically connects with chip assembly 40, when smart machine powers on, is supplied power to by chip assembly 40
Signal imitation module 10, signal imitation module 10 then sends a hot plug signal to chip assembly 40, with simulating external access display dress
Put the insert state of 60, that is, chip assembly 40 receive hot plug signal whether independent of external connection display apparatus 60 plug with
No, even if when external connection display apparatus 60 is extracted, still can be by the insertion signal of signal imitation module 10 analog display unit 60
And send to chip assembly 40, received by chip assembly 40 is the most lasting detection signal, is being not detected by hot plug
Under the change of signal level, chip assembly 40 will not actively switch display pattern, to realize maintaining display device 60 insert state
Purpose.
-information storage module electrically connects with chip assembly 40, is stored with an initial information, and initial information can include example
As: optimal shows picture, the resolution of display picture, the refresh rate etc. of display picture, and after motherboard 30 powers on, information is deposited
Storage module is powered by motherboard 30, and sends the initial information of storage to chip assembly 40, then have setting of this motherboard 30
The picture of standby display is fixed according to the setting of initial information, even if external display device 60 accesses, only by display picture
Face data channel receives picture data, will not affect that the display part of the chip assembly 40 of motherboard 30.
After there is above-mentioned configuration, during external connection display apparatus 60 hot plug, first by signal imitation module 10 mould
Intend display device 60 all the time in the state inserted, for the operation of hot plug, will not affect that the display of motherboard 30 and make
With；Secondly display device initial information, when motherboard 30 powers on, interface are provided by the information storage module that motherboard 30 is built-in
Whether assembly 50 exports corresponding correct picture maintaining by the initial information reading this display device 60 and persistently exports, and connect
Enter display device 60, that whether display device 60 is in hot pluggable condition is unrelated.It is to say, reality is at external connection display apparatus 60 not
Accessing, it is impossible under providing in the case of the information of display device 60, information storage module sets on behalf of the best image providing setting
Determine information (information storage module can be read by motherboard 30 to obtain), the most persistently export to realize showing.
For the different configurations of interface module 50, the concrete line construction of signal imitation module 10 is the most different, such as:
1. interface module 50 includes USB interface
Refering to Fig. 3, USB interface includes the RGB line road obtaining display picture, on this RBG circuit, connects and has signal imitation
Module 10, signal imitation module 10 includes RC circuit and three groups of field effect transistor unit, each group in three groups of field effect transistor unit
It is connected with one of RGB line road, and is connected with RC circuit, RC circuit ground connection simultaneously.Field effect transistor unit simulation external connection display apparatus
The access state of 60, specifically field effect transistor unit includes a field effect transistor and load resistance, the drain D of field effect transistor and load
Resistance connects, and is connected in parallel to RGB line road, source S ground connection, and grid G is connected with RC circuit.Do not access at external connection display apparatus 60
Under, the chip assembly 40 of motherboard 30 still can access the load circuit in signal imitation module 10, is thus judged as display dress
Put 60 accesses, thus realize the purpose of analog display unit 60.
2. interface module 50 includes digital interface
Refering to Fig. 4, between the hot plug signal line being provided with in chip assembly 40 and digital interface, it is provided with analog signal lines,
Signal level is sent so that the hot plug detection signal 51 being connected to chip assembly 40 detects all the time to hot plug signal line
Signal be high level, chip assembly 40 judges that display device 60 accesses all the time.
It is understood that for other kinds of interface, signal imitation module 10 can analog chip assembly pointedly
The signal that 40 judged display devices 60 access, to realize the lasting output of motherboard 30 part.
Refering to Fig. 5, one preferably or in alternative embodiment, information storage module is information storage unit 20 (EDIDEEPROM),
It is connected with display device 60 communication channel being connected to chip assembly 40, relevant display device 60 and performance thereof in it, can be comprised
Parameter, such as supplier information, maximum image size, color arrange, factory default put, the restriction of frequency range, display device
60 titles and serial number etc..This EDID is made up of 128 byte character strings, and burning is saved in the EEPROM within motherboard 30.
After there is above-mentioned motherboard 30, can be applied directly in smart machine, such as bank self-help cash dispenser, Intelligent Service eventually
End, automatic teller machine etc..Owing to signal imitation module 10 and information storage module can be set directly on motherboard 30, in smart machine
Portion's structure can directly be applied without change.During use, access even without display device 60, the display picture of motherboard 30 part
Face keeps fixing, hot plug display device 60, and its picture also will not change, and motherboard 30 only need to send display to display device 60
Picture, on key frame without impact.
It should be noted that, embodiment of the present utility model has preferably implementation, and not this utility model is appointed
The restriction of what form, any one skilled in the art changes possibly also with the technology contents of the disclosure above or is modified to
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model
Any amendment that above example is made or equivalent variations and modification, all still fall within the range of technical solutions of the utility model.
