Embodiment
Carry out the various exemplary embodiments of detailed description of the present invention now with reference to attached drawing.It should be noted that：Unless in addition have
Body illustrates that the unlimited system of component and the positioned opposite of step, numerical expression and the numerical value otherwise illustrated in these embodiments is originally
The scope of invention.
The description only actually at least one exemplary embodiment is illustrative to be never used as to the present invention below
And its application or any restrictions that use.
It may be not discussed in detail for technology, method and apparatus known to person of ordinary skill in the relevant, but suitable
In the case of, the technology, method and apparatus should be considered as part for specification.
In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent attached drawing in a attached drawing.
Method shown in Figure 1, comprises the following steps.The targeted display device of wearing of the present invention includes being used to connect
At least two interfaces that host carries out data transmission.
In step 11, display device allocation identification is worn to be described.
Such as wear the manufacturer of display device and wear the unique mark of display device distribution for what it dispatched from the factory, and by this
Unique mark write-in is worn in some memory block of display device.
In another example this, which wears display device, includes USB interface, while it is provided with the usb hub being connected with the USB interface
Chip.Wear the manufacturer of display device and can configure each title and wear usb hub chip in display device so that is each
A usb hub chip generates unique mark (commonly referred to as Container ID, 16 byte longs) after working on power.
In step 12, the display device of wearing sends the mark by each interface to the host, for described
Host identifies wears display device corresponding to each interface.
By taking second example in step 11 as an example, different display devices of wearing is sent out by respective USB interface to host
Send different Container ID.So as to which host can send identical Container ID's by these USB interfaces to host
It is same to wear display device that USB interface is corresponding.
This method is also applied for wearing the video data interface of display device, video data interface such as DisplayPort
Interface, HDMI interface, MHL interface etc..General display device of wearing can send extension display by video data interface to host
Mark data (extended display identification data, EDID).EDID is a kind of standard data format, its
In comprising such as supplier information, maximum image size, color is set, factory default is put, frequency range, display title, sequence
The information such as row number.The mark in step 11 is write in EDID, and EDID is sent to host by video data interface, this
Sample host can identify that each foregoing wears display device uniquely corresponding mark from the EDID received.
By above method, host can correspond to the interface for being sent to same identification information same to wear display and set
Standby interface, connects more titles so as to fulfill host and wears display device.
Shown in Figure 2 wears display device 20, to realize foregoing method.Wearing display device 20 is included at least
Two are used to connect the interface that host carries out data transmission：First interface 21, second interface 22 ..., the n-th interface 2n.Wear
Display device 20 has mark, and each of the above interface is both configured to send this mark to host.So as to which host can be sentenced
The disconnected interface for sending like-identified corresponds to same title and wears display device.
Shown in Figure 3 wears display device, this is a specific example.Wearing display device 30 includes one
USB interface 31, the usb hub chip 32 being connected with USB interface, video data interface 33, be connected with video data interface 33
Control module 34, wherein control module 34 is also connected with usb hub chip 32.
The algorithm that usb hub chip 32 is selected according to manufacturer, it can all generate one only after each electrifying startup
One mark.When host is connected by USB interface 31 with wearing display device 30, host can read USB by USB interface 31
The mark that hub chip 32 is generated.This mark can be also sent to control module 34 by usb hub chip 32, control mould
This mark is stored in the memory of itself by block 34, and by this mark write-in extending display identification data, controls mould
Block 34 sends this extending display identification data by video data interface 33 to host.
By above step, host, which can be known, is sent to the USB interface for including same identification information and video counts
The interface of display device is worn for same title according to interface.
Shown in Figure 4 wears display system, including two are worn display device 20a, 20b and host 40.
Wearing display device 20a includes first interface 21a, second interface 22a, wears display device 20b and is connect including first
Mouth 21b, second interface 22b, host 40 include four interface 41-44.
Wherein, it is two instantiations that display device 20 is worn shown in Fig. 2 to wear display device 20a, 20b.
The interface 41,42 of host 40 receives the mark for wearing display device 20a transmissions, and the interface 43,44 of host 40 receives
Wear the mark of display device 20b transmissions.So as to which host 40 would know that interface 41,42 corresponds to one and wears display device, interface
43rd, 44 correspond to another wear display device.
Although some specific embodiments of the present invention are described in detail by example, the skill of this area
Art personnel it should be understood that example above merely to illustrating, the scope being not intended to be limiting of the invention.The skill of this area
Art personnel are it should be understood that without departing from the scope and spirit of the present invention can modify above example.This hair
Bright scope is defined by the following claims.
