Description
Technical field
The utility model relates to display terminal MHL interfacing field, particularly the interactive display terminal of a kind of mobile phone based on the MHL interfacing.
Background technology
Mobile High-Definition Link (MHL) is a kind of audio-visual standard interface that connects portable consumer electronic device.Present mobile phone extend out that interface only is confined to converse and data content on transmission.Because the display frame of mobile phone is limited, keyboard, touch screen all is subjected to the restriction of area and power above the voice, can't, easily operation free like that with the desktop computer.Therefore this audio-visual standard interface of what use is made of realizes that mobile phone and display terminal interaction are the demands in market.
Summary of the invention
The purpose of this utility model provides the interactive display terminal of a kind of mobile phone based on the MHL interfacing, can be the mobile phone interaction with what be provided with the MHL interface.
The utility model adopts following scheme to realize: the interactive display terminal of a kind of mobile phone based on the MHL interfacing, comprise the microcontroller that is connected with HDMI video interface circuit, human-computer interaction module and audio-frequency module, it is characterized in that: described microcontroller also is connected with the MHL receiver module, the input of described MHL receiver module is provided with the MHL interface circuit, in order to the mobile communication that is provided with the MHL interface.
In the utility model one embodiment, described human-computer interaction module is a touch display screen.
In the utility model one embodiment, described microcontroller also is connected with usb circuit.
The utility model adds the MHL interface circuit in the circuit of display terminal, the video of mobile phone and control information can be transformed into this display terminal shows synchronously, solve the operating difficulties that causes owing to mobile phone screen is little and watched the unsharp problem of mobile video, circuit structure is simple, has good practical values.
Description of drawings
Fig. 1 is the circuit structure principle schematic of the utility model embodiment.
Fig. 2 is the circuit structure principle schematic of another embodiment of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, present embodiment provides a kind of mobile phone based on the MHL interfacing interactive display terminal, comprise the microcontroller that is connected with HDMI video interface circuit, human-computer interaction module and audio-frequency module, described microcontroller also is connected with the MHL receiver module, the input of described MHL receiver module is provided with the MHL interface circuit, in order to the mobile communication that is provided with the MHL interface.
By the MHL interface, mobile phone can send to display terminal with multiple media formats data, it comprise MPEG4, H.264, AVI, Quick time or windows media, this MHL interface has only 5 pin, wherein 4 pin are used for transmission of audio and vision signal specially, and 1 pin is used for controlling specially.It equal TMDS and CEC in other words DDS combine and carry out total control, be a control bus, had this control bus to carry out omnibearing control to all Voice ﹠ Videos, it becomes the transmission of the storage of data and data and is more prone to.The operator can be implemented in mobile phone and uses the related application control, is simultaneously displayed on the display screen of display terminal.The operator also can utilize the related application control on touch-control or the peripheral hardware realization control smart mobile phone on display in addition.Thereby reach the effect same with the desktop computer system, accomplish mobile phone and display terminal interaction.
See also Fig. 2, Fig. 2 is the circuit theory schematic diagram of another embodiment of the utility model, and among the figure, this display terminal has been set up usb circuit, and this usb circuit has been expanded the function of system, can realize the transmission of data, and the broadcast of USB flash disk video/audio.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
