Data input, and between major-minor processor, can not only be mutually in step and can be mutual indepedent, so as to fulfill double screen with showing, two separate display.
Description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, the application's is other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is shown according to a kind of for same aobvious, two separate display the system schematic of double screen of the application one side；
Fig. 2 shows a kind of for same aobvious, two separate display the method flow diagram of double screen according to the application.
Fig. 3 shows according to the application whether there is signal according to external HDMI in, judges double screen with aobvious, two separate display
Flow chart.
Fig. 4 is circuit connection diagram.
Specific embodiment
The application is described in further detail below in conjunction with the accompanying drawings.
A kind of shown in Fig. 1-4 realizes double screen with aobvious, the intelligent optical projection system of two separate display, wherein, which includes the
One screen 1（LCD touch panels）, the second screen 2（Light engine）, dual processors（Primary processor, auxiliary processor）, power management system
System, audio-frequency amplifier, loud speaker.
Specifically, Fig. 2, first screen 1 are seen（LCD touch panels）Connect primary processor, primary processor control display
First image information, and the auxiliary processor with being connected the second screen 2 communicates；Second screen 2（Light engine）Connect auxiliary place
Device is managed, auxiliary processor controls the second screen 2 to show the second image information, meanwhile, it communicates with primary processor；The inside
HDMI data cables, uart control lines connect the primary processor of first screen 1 and the auxiliary processor of second screen 2.
External interface includes, network interface RJ45, USB, WIFI, card reader card reader.
After system electrification, primary processor reads the input signal of outside port, RJ45, USB, WIFI etc., if has
External data signal inputs, and vision signal therein after Video Decoder is handled, passes through the first screen 1（LCD touch-controls
Panel）Show external input signal.At the same time, auxiliary processor detects its outside port, HDMI, if has signal input.So
Afterwards, primary processor sends a signal to auxiliary processor, inquires the external HDMI ports of auxiliary processor and whether has signal input, if do not had
Have, then（Connect the first screen）By the form of internal HDMI data cables, the decoded video of primary processor is believed for primary processor
Number auxiliary processor is transmitted to, passes through the second screen 2（Light engine）It has been shown that, so as to fulfill double screen with aobvious.All signals are transferred to connect
The main processor system processing of the first screen is connected to, the primary processor of so described first screen 1 is auxiliary with second screen 2
The method that a uart communications can be established between processor neatly realizes the communication between two screens, because both sides
Handling function be all the interface of standard, so being highly susceptible to programming.
Here, the primary processor of first screen is passed by the internal HDMI data line transfer data by UART
Defeated order controls the display content of second screen 2（Such as second image information）.Moreover, the data of the transmission and
Order can be by User Defined, and the interaction protocol between first screen 1 and second screen 2 can flexibly change.
This application can be applied to the display scene of other forms, such as DLP, LCOS, 3LCD etc..
Preferably, second screen 2 is additionally operable to the 3rd image information of display.
After system electrification, primary processor reads the input signal of outside port, RJ45, USB, WIFI etc., if has
External data signal inputs, and vision signal therein after Video Decoder is handled, passes through the first screen 1（LCD touch-controls
Panel）Show external input signal.At the same time, auxiliary processor detects its outside port, HDMI, if has signal input.So
Afterwards, primary processor sends a signal to auxiliary processor, inquires the external HDMI ports of auxiliary processor and whether has signal input, if
Have, then（Connect the first screen）The input signal control of HDMI ports is transferred to auxiliary processor, by auxiliary processing by primary processor
Input signal is carried out the decoding of vision signal, after decoding, the second screen 2 for being controlled by auxiliary processor by device（Light engine）It is aobvious
Show, transmitted between the primary processor of so described first screen 1 and the auxiliary processor of second screen 2 by a uart
Control signal neatly realizes the communication between two screens, so as to fulfill the different aobvious of double screen.In such cases, primary processor
The vision signal of reception be not transferred to auxiliary processor.
Here, the primary processor of first screen receives external RJ45, USB, WIFI signal, and control first
Screen display, it is described, by UART transmission order and auxiliary processor communication, but not by HDMI number is transmitted to auxiliary processor
According to the display content of second screen 2 for having auxiliary processor control will not be controlled（Such as second image information）.
In such cases, the first screen 1 of the primary processor control and 2 phase of the second screen of the auxiliary processor control
It is mutually independent, except carrying out exchanging for simple control signal and audio signal, video data will not be transferred between two processor.Work as institute
When stating the first screen 1 of master controller in a dormant state, the second screen 2 of the auxiliary processor control can also independently be shown
Content.
Preferably, the auxiliary processor of the primary processor of the first screen 1 of the connection and the second screen 2 of the connection, is based on
Connect the Android system of the primary processor of the first screen.
For example, the main controller controls that first screen 1 connects have corresponding Android system, with second screen 2
The assistant controller of connection does not have corresponding Android system, so not only reduces cost, and convenient for the communication of major-minor processor
Coordinate, convenient for the display control to two display screens.The exploitation of the application program of Android system, when not having HDMI signals
During input, can also the video data of first screen 1 transmit to second screen 2, then cooperative work；If there is H
DMI signals input, and main process task needs auxiliary processor to be transferred to handle the control of external HDMI signals.Certainly it is main
If processing is that by software development, can serve as the angle of the remote control touch plate of auxiliary processor without the processing of extraneous port data
Color.It that is, can also be by the main place of first screen 1 if the system of the auxiliary processor of described second screen 2 is excessively busy
The idling-resource of reason device pair completes some except other decoded work of video.
Preferably, the quantity for the second screen that the auxiliary processor controls is one or more.
For example, multiple auxiliary processors and its second screen of control can be extended to by Uart data cables, it is described
The primary processor of the first screen is controlled to transmit data and order, pipe to multiple auxiliary processors by the Uart data cables
Manage the display content of multiple auxiliary processors and its second screen of control.Moreover, whether number is had according to external HDMI ports
According to input, the display content to realize multiple screens can be identical or different.
