Description of drawings
Fig. 1 is the circuit frame figure of the external display controller of the present invention's intelligence handheld terminal;
Fig. 2 is the process flow diagram of the external display control method of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail, but embodiment of the present invention is not limited thereto.
Embodiment
As shown in Figure 1, the external display controller of present embodiment intelligence handheld terminal comprises display screen and coupled vision signal conversion chip; Touch-screen and coupled touch-screen control chip; Audio unit and coupled loudspeaker module; And communication unit; Said communication unit does not link to each other with audio unit, vision signal conversion chip and touch-screen control chip.
Said communication unit is wire communication unit or wireless communication unit, and the wire communication unit is I/O interface many Pin interface or USB interface etc., and wireless communication unit has wifi communication unit, bluetooth-communication unit or RFID communication unit etc.In addition, said communication unit is a kind of in above-mentioned wire communication unit or the wireless communication unit or is the combination of above-mentioned communication unit.When communication unit was the wire communication unit, external display controller linked to each other through the external interface of wire communication unit with the external smart handheld terminal; When communication unit is wireless communication unit, the wireless communication module wireless connections of wireless communication unit and intelligent handheld terminal.For example wireless communication unit is under the situation of bluetooth, and data are obtained in the Bluetooth wireless communication module of this external display controller and the bluetooth module wireless connections of intelligent handheld terminal.Certainly, wireless communication unit and wire communication unit also can be present on the external display controller simultaneously.
Should the demonstration of intelligence handheld terminal current screen send on the vision signal conversion chip of present embodiment through the video data channel of its external interface in real time at the software kit that moves on the intelligent handheld terminal, thereby on display screen, show synchronously.
This software sends to the voice data of intelligent handheld terminal on the audio unit of this novel practical through the voice-grade channel of its external interface simultaneously in real time, after audio unit (possibly decode in this unit) processing and amplifying, on the loudspeaker module, is playing back with better tonequality and volume.
The more important thing is; This software receives the contact screen information (interruption that operating personnel send simultaneously through the touch-screen control channel of interface; Position and gesture etc.); Convert these control informations to information that intelligent handheld terminal operating system can be accepted and respond, thereby reach the purpose of on the touch-screen of the external display controller of present embodiment, operating and control intelligent handheld terminal.
