Described wireless display apparatus comprises power management module and the battery of oneself, battery information returns to described intelligent mobile phone by processor, therefore the battery information on described wireless display apparatus output interface is the battery information of described wireless display apparatus, but not described intelligent mobile phone carries the battery information of the described intelligent mobile phone that shows screen display.
Above-mentioned application process all can be supported multiple input modes:
The first input equipment is the touch-screen of intelligent movable equipment itself and button, sensor;
The second is touch-screen above the wired or wireless demonstration output equipment and button, sensor;
The third is circumscribed USB mouse-keyboard or bluetooth mouse keyboard;
When the external described Wireless Display output equipment of described intelligent movable equipment, can support to connect simultaneously a plurality of wireless display apparatus, these display devices are shared same display image content and sound, and can carry out the timesharing input operation at display device.
The above mentions described intelligent movable equipment and supports three kinds of input equipments, touch-screen on the intelligent movable equipment and button only work to the application above the intelligent movable device display screen, touch-screen on the external demonstration output equipment and button only work to the application above the external demonstration, the USB keyboard and mouse of expansion or bluetooth keyboard mouse use above then can switching to different display screens, and the user can only use mouse-keyboard to remove to control two equipment like this.The USB mouse can switch between two display screens, then enters another display screen when shifting out one of them display screen scope; And the focus of USB keyboard input, then the focus with the input of USB mouse is as the criterion.
Free hand drawing shape shows the two methods that show of output module processor expansion:
Described intelligent movable equipment needs to export two different operation display interfaces, therefore require the primary processor of described intelligent movable equipment to have two demonstration output interfaces, but there are a lot of processors only to have one and show output interface, we need to expand another display interface out by other means in this case, such as drawing display interface by NandFlash interface or the external extended chip of SDRAM/DDR interface.
In this case, use the output display of outside extended chip generally all poor, if and this display interface is received on the external demonstration output equipment, display effect will be more bad, therefore preferably connect the demonstration output that the intelligent movable device handler carries when the work of expansion display interface, external display device then is connected to the display interface of intelligent movable device handler.In this case, the demonstration output of self needs can cause the display effect of self relatively poor with the expansion display interface when intelligent movable equipment is expanded outside demonstration, also can increase the power consumption of system when expanding the chip operation that shows in addition.Therefore we have imagined a kind of scheme, adopt the mode of switching, if just intelligent movable equipment self work expansion is outside when showing then the display interface connection device that uses the intelligent movable device handler to carry shows output; Expansion is outside to be shown when exporting if need, then output to the acquiescence display interface that intelligent movable equipment carries demonstration and switch to outside the demonstration in the output former, and intelligent movable equipment carries the display interface that shows the connection expansion, no matter so whether external demonstration output equipment mainly all is that the display interface that processor carries is being worked.
The software processing mode of dual input output:
Described intelligent mobile phone is supported self the small screen and external large scale display, and support above-mentioned three kinds of input modes, therefore in the software systems of intelligent mobile phone, there are two application managers, two interface output processing subsystems and an input processing subsystem, all input equipments are all processed by this input subsystem, then being distributed to corresponding application manager according to different device attributes processes, different application manager interfaces outputs in the corresponding interface output processing subsystem, and then exports to corresponding display device and show.Application program use for the small screen output that runs on equipment self carries button, touch-screen, sensor as input equipment; For the application program that runs on external demonstration output, then use button, touch-screen, sensor equipment on the external radio display; And for USB keyboard/mouse or bluetooth keyboard/mouse, then can between the application program of two different outputs, switch, when mouse moves when exceeding intelligent mobile phone self the small screen indication range, then switch the application program input as external large-screen output, when exceeding the external-connection displayer indication range, then switch the application program input as self the small screen output, the input of keyboard then corresponds to corresponding application program according to the input indication of mouse.
Because external radio display may have multiple different resolution, software systems then can read by wired or wireless passage the optimum resolution of external-connection displayer support and automatically export adaptive.
According to different application scenarioss, in some occasion, need the different interface of built-in and external demonstration, some occasion is then wished the interface that reality is identical or is switched single display, in this occasion, the use pattern of built-in demonstration or the use pattern of external demonstration need be distinguished by system, only process one group of input-output equipment.
