Abstract
The invention discloses a liquid crystal display with a digital multi-media player function, which comprises a display screen, a circuit board, a VGA (Video Graphics Array) signal interface, a DVI (Digital Visual Interface) and HDMI (High Definition Multimedia Interface) signal interface and a DMP (Digital Media Player) interface, wherein the display screen, the VGA signal interface and the DVI and HDMI signal interface and the DMP interface are respectively and electrically connected with the circuit board, the main control chip of the circuit board is provided with DMP playing software, and the main control chip reads information in a storage, which is input by the DMP interface, and outputs the information to the display for playing after decoding the information. By adopting the technical scheme, the invention improves the method that the traditional display plays video, audio and text files by externally connecting an external signal source and directly displays and plays the video, the audio and the text files in a storage card or USB storage connected through an interface through a digital multi-media playing module in the liquid crystal display without the external signal source and ensures that the liquid crystal display has a function of playing the digital multimedia file independently.
Description
Technical field
The present invention relates to field of liquid crystal, relate in particular to a kind of LCD with the digital multimedia playing function.
Background technology
LCD generally comprises VGA (striograph figurate number group also is D-sub) signaling interface or DVI (digital video) signaling interface, and its effect is to connect PC (computer) or other players as terminal presentation facility.The VGA interface can only be accepted simulating signal input, the most basic comprise R G B H 5 components of V (being respectively red, green, blue, row, field), no matter, comprise above these 5 components in its signal at least with the interface access of which kind of type.The DVI interface is a kind of signaling interface that grows up along with the development of digitizing display device in recent years.Computing machine directly is sent to display message in the display device in the mode of digital signal, adopts the picture quality of the display device of DVI interface to want better.The DVI interface has been realized real plug and play and hot plug in addition, has exempted and need shut down computer in connection procedure or the trouble of other players.High-end LCD also is provided with the HDMI interface except that VGA, DVI signaling interface, HDMI interface (High DefinitionMultimedia Interface) has the frequency range of 10.2Gbps, image quality clearly can be provided, output does not have the vision signal of compression, and because audio/video adopts same cable and sound signal, only need the HDMI line just can output image and decoded digital canned data, read and the decoded digital canned data by main frame.But the function of display that is provided with these three kinds of signaling interfaces is less, purposes is limitation, can't read and the decoded digital canned data, can't independently produce sound and vision signal, can only be as terminal presentation facility, read and the decoded digital canned data by main frame, therefore existing display can't the independent displaying displaying video, audio frequency and textual number multimedia file, can only be as supporting terminal presentation facilities such as computing machines.
Summary of the invention
The purpose of this invention is to provide a kind of information that can read storage card, play-over the LCD of the band digital multimedia playing function of video file, audio file and text message.
The present invention is by the following technical solutions: LCD of the present invention comprises display screen, circuit board, VGA signaling interface and DVI, HDMI signaling interface, display screen, VGA signaling interface and DVI, HDMI signaling interface are electrically connected with circuit board respectively, wherein the main control chip of circuit board is equipped with digital multimedia (being called for short DMP:Digital MediaPlayer) playout software, LCD also is provided with the DMP interface, the DMP interface is electrically connected with circuit board, main control chip reads information in the storer of DMP interface input, and will export display behind the information decoding to and play.
LCD also is provided with the audio frequency delivery outlet of external speaker, headset, and the audio frequency delivery outlet is electrically connected with circuit board.
When described DMP interface inserts storage card or USB device, main control chip reads information in the storer, and temporarily leave in RAM (random access memory) chip, behind information decoding, convert the video or the audio source signal that allow display or audio amplifier, headset receive to, again by main control chip with this video or audio source signal output.
Described RAM chip adopts the Amlogic7223 chip.
The present invention adopts above technical scheme, having abandoned traditional monitor broadcast Video, Audio and picture signal needs the way of outside source, but read storage card or USB device canned data and play-over by the DMP interface, save the equipment that the outside provides signal source, realize the saving of the energy and reducing of space.When the user inserts USB device or storage card on the LCD DMP interface, allow main control chip read information such as wherein music, film by Control-Menu operation, leave in then in the RAM chip, these data temporarily can't be play, must carry out rasterization process to decoded information through the RAM chip, become and to allow behind the video or audio source signal that display or audio amplifier receive, export by main control chip, cooperate the LCD liquid crystal display drive circuit on the circuit board, just can realize the broadcast and the demonstration of audio/video file.The invention enables traditional monitor to have multimedia function.
The present invention has improved the way of traditional monitor displaying video, audio frequency and the external outside source of text needs, but directly display the play through interface continuous storage card or the video in the USB storage, audio frequency and textual number multimedia file by the digital multimedia playing module in the LCD, save outside source, make LCD have the function of independent play-out digital multimedia document.
Description of drawings
Now in conjunction with the accompanying drawings the present invention is further elaborated: Fig. 1 is the structural representation of LCD of the present invention.
Embodiment
As shown in Figure 1, LCD 1 of the present invention comprises display screen 11, circuit board 15, VGA signaling interface 12 and DVI, HDMI signaling interface 13,14, display screen 11, VGA signaling interface 12 and DVI, HDMI signaling interface 13,14 are electrically connected with circuit board 15 respectively, wherein the main control chip 151 of circuit board 15 is equipped with digital multimedia (being called for short DMP:Digital Media Player) playout software, LCD 1 also is provided with DMP interface 16, DMP interface 16 is electrically connected with circuit board 15, main control chip 151 reads information in the storer of DMP interface 16 input, and will export display 11 behind the information decoding to and play.
Above-mentioned LCD 1 also is provided with the audio frequency delivery outlet 17 of external speaker, headset, and audio frequency delivery outlet 17 is electrically connected with circuit board 15.
When described DMP interface 16 inserts storage card or USB device, main control chip 151 reads information in the storer, can temporarily leave in RAM (random access memory) chip 152, RAM chip 152 can adopt the Amlogic7223 chip, behind information decoding, convert the video or the audio source signal that allow display 11 or audio amplifier, headset receive to, again by main control chip 151 with this video or audio source signal output.
