Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1-2 the utility model relates to a two screens system of showing separately under android system, including control module to and carry out the display output module, audio input module, audio output module, USB expansion interface module, peripheral hardware module, the network module that the communication is connected with control module, control module includes CPU processor module and hard disk storage module, the memory module who carries out data interchange with CPU processor module, display output module includes HDMI output module, MIPI _ DSI output module, MIPI-HDMI conversion module, shows main screen, shows vice screen, MIPI _ DSI output module converts MIPI output signal into the HDMI signal through MIPI-HDMI conversion module.

As an embodiment of the utility model, the network module includes wired network module and wireless network module, the wireless network module includes WIFI focus module and bluetooth module, and this system supports wired network and wireless network communication, convenient to use, and is compatible strong.

As an embodiment of the utility model, still include the power module who is connected with control system, power module provides the electric energy for entire system.

In the aspect of hardware, the HDMI output module connected with the main screen and the MIPI _ DSI output module connected with the auxiliary screen are arranged on the mainboard of the terminal, a chip of the MIPI-HDMI conversion module is added between the auxiliary screen and the MIPI _ DSI output module, and the bright screen output signal of the MIPI _ DSI is converted into an HDMI signal, so that the effect of double HDMI output is achieved, the terminal interface is neat and attractive, wiring is convenient, and the terminal can be adapted to various display screens.

In the aspect of software, the hardware terminal can support the functions of double-screen simultaneous display or double-screen different display of a plurality of different applications, and can be applied to the following three scenes.

The use mode one: the dual-screen different display system is used for playing programs, and the programs with different (or same) contents can be played on two screens at the same time, wherein the program contents comprise video, pictures, texts, tickers, web pages, PDFs, OFFICE files, real-time weather, clocks and other forms. When the dual-screen differential display is not started, all program elements are rendered by the main screen according to a programming mode, the same content can be automatically and simultaneously displayed on the auxiliary screen, if the dual-screen differential display is started, the edited auxiliary screen program elements can be played on the auxiliary screen on the basis of the main screen playing, different contents can be played on the main screen and the auxiliary screen, the dual-screen differential display can support simultaneous playing of a plurality of videos, but in order to avoid interference of sound, the videos on the auxiliary screen are output without sound.

The utility model supports the synchronous playing of double-screen video or picture under the support that the double-screen can display video, thereby deriving a plurality of different applications, cutting the wide-screen video of a video (such as a film) into a left part and a right part, synchronously playing on the main screen and the auxiliary screen, and playing the video on the display screen in a splicing screen mode, thus having better playing effect than a single screen; for another example, a large poster can be cut into 6 pictures of 3 × 2, and 6 large screens of 3 terminals are used, and corresponding positions are set respectively and are played simultaneously, so that a very shocking and cool advertising effect is achieved; the main screen can also be used for selecting to play videos, the auxiliary screen can be used for simultaneously and synchronously playing pictures or word descriptions, and the like, so that the effect that the double screens of the same terminal are used for propaganda in different modes is achieved.
