It connects, 50 control terminal CTR2 of second display screen is connected for second display screen 50；Select end TE, 40 control terminal CTR1 of the first display screen,
50 control terminal CTR2 of second display screen is GPIO mouthfuls；MIPI switch 22 has input terminal, controlled end, the first output end, second
The input terminal of output end, MIPI switch 22 is connect with MIPI interface 21, and the controlled end of MIPI switch 22 is connect with selection end TE,
First output end of MIPI switch 22 is connected for the data receiver of the first display screen 40, and the second output terminal of MIPI switch 22 supplies
The data receiver of second display screen 50 connects；When needing the first display screen 40 to show information, 20 control selections of chip are controlled
TE is held to export first selection signal, so that the input terminal of MIPI switch 22 is connected to the first output end, MIPI interface 21 is defeated
Data out are transmitted to the first display screen 40, and control chip 20 controls multiple first display screen, 40 control terminal CTR1 transmissions and is used for
Control the control signal of the first display screen 40 work；When needing second display screen 50 to show information, the control control choosing of chip 20
It selects end TE and exports the second selection signal, so that the input terminal of MIPI switch 22 is connected to second output terminal, by MIPI interface 21
The data of output are transmitted to second display screen 50, and control chip 20 and control multiple 50 control terminal CTR2 of second display screen transmission use
In the control signal that control second display screen 50 works.
The baseband processor that chip 20 can be double-screen intelligent terminal is controlled, CPU is also possible to.MIPI(Mobile
Industry Processor Interface), i.e. mobile industry processor interface.Control chip 20 in the present embodiment can be with
Only there is a MIPI interface 21, it is possible to have multiple MIPI interfaces 21, and be only two displays with a MIPI interface 21
Screen transmission data.
The signal that MIPI interface 21 is exported belongs to high speed signal, according to different display screens to data demand, MIPI interface
21 working frequency can be different, but usually all in 250MHz or more；If the resolution ratio of LCD screen is 600x1024, frame per second is
57HZ, thus MIPO interface to LCD screen transmit data when, working frequency substantially 283.679424Mhz.
In the present embodiment, switched over using the data of MIPI switch 22 pairs of MIPI interfaces 21 transmission.MIPI switch 22
The switch speed of response with higher, and the frequency of selected MIPI switch should be not less than the working frequency of MIPI interface 21
Bandwidth, to guarantee that the data transmitted to MIPI interface 21 carry out quickly switching to the first display screen 40 or second display screen
50, guarantee display speed and quality of the information on the first display screen 40 or second display screen 50.
It controls chip 20 and first selection signal and the second selection signal is exported by selection end TE, certainly at a time only
First selection signal or the second selection signal can be exported.Selection end TE be control chip 20 GPIO mouth, first selection signal with
Second selection signal can be the high and low level exported from GPIO mouthfuls.
Table 1 is please referred to, when selecting end TE output high level, the input terminal of MIPI switch 22 is connected to the first output end,
The data that MIPI interface 21 exports are transmitted to the first display screen 40, to show on the first display screen 40；When selection end TE output
When low level, the input terminal of MIPI switch 22 is connected to second output terminal, and the data that MIPI interface 21 exports are transmitted to
Two display screens 50, to be shown on second display screen 50.
Table 1
| Select end TE level | Connect the display screen at the end MIPI end |
| 0 | Second display screen 50 |
| 1 | First display screen 40 |
By the way that MIPI switch 22 is arranged, for since certain moment or certain period needs are shown on the first display screen 40
When information, by the configuration to control chip 20, make MIPI interface 21 and select the cooperation of end TE, makes to select the high electricity of end TE output
It is flat, while the output of MIPI interface 21 being made to correspond to the data to show on the first display screen 40, so that the first display screen
40 can accurately receive the data issued in MIPI interface 21.When needing to show information on second display screen 50, lead to
Crossing makes to select end TE output low level, while the output of MIPI interface 21 being made to correspond to the number to show on second display screen 50
According to so that second display screen 50 can accurately receive the data issued in MIPI interface 21.Therefore it realizes at two
Show the effect of screen display different content.
First display screen, 40 control terminal CTR1 and 50 control terminal CTR2 of second display screen (being referred to as display screen control terminal) is used
In the work of control display screen (general designation of the first display screen 40 and second display screen 50), for example, the control brightness of screen, light on and off,
Reset, interrupt etc..
It in one embodiment, include in the first reseting controling end and first in multiple first display screen, 40 control terminal CTR1
The broken ends of fractured bone；It include the broken ends of fractured bone in the second reseting controling end and second in multiple 50 control terminal CTR2 of second display screen；First resets control
End processed is connected for the reset receiving end of the first display screen 40；The broken ends of fractured bone is connected for the first display screen 40 in first, in control chip
20 and the first Transmission signal between display screen 40；Second reseting controling end connects for the reset receiving end of second display screen 50
It connects；The broken ends of fractured bone is connected for second display screen 50 in second, with the Transmission signal between control chip 20 and second display screen 50.
Reseting controling end (being referred to as the first reseting controling end, the second reseting controling end) can be different in double-screen intelligent terminal works
Chang Shi resets display screen.Interrupt signal can be sent from display screen to control chip 20, can also be from control chip 20 to aobvious
Display screen is sent.
In low side intelligent terminal platform, control chip 20 has more rich GPIO mouthfuls of resource, therefore in the present embodiment,
40 control terminal CTR1 of the first display screen, 50 control terminal CTR2 of second display screen is set to be connected directly to the GPIO of control chip 20
Mouthful, control control chip 20 individually the first display screen 40, second display screen 50.The present embodiment takes full advantage of control
GPIO resource on chip 20, to realize control to the first display screen 40 and second display screen 50；
Also, the present invention is by setting MIPI switch 22, to make 21 He of MIPI interface by the configuration to control chip 20
The cooperation for selecting end TE, realizes and sends data on two display screens, to meet the display demand of two display screens.
Therefore the present invention program passes through the coordination control to MIPI switch 22, selection end TE, the first control terminal, the second control terminal
System, makes full use of low side intelligent terminal platform GPIO mouthfuls of resource abundant, in the case where 21 quantity of MIPI interface is poor, realizes
Shuangping san control.
In the present embodiment, control chip 20 also has synchronous end, and shuangping san control platform also has synchronization signal switching
Switch 23；Synchronization signal, which switches switch 23, has controlled end, input terminal, the first output end and second output terminal；Synchronization signal is cut
