Abstract
A method for automatically switching off plasma display screen includes inputting mode selection signal to plasma display unit and receiving said signal by built-in master chip of plasma display unit, starting up audible energy-saving mode to automatically switch off video output signal and to only output audio signal by master chip when only audible mode is selected from mode selection signal, starting up normal mode to output audio-video signal normally on plasma display screen by master chip when normal mode is selected from mode selection signal.
Description
One, technical field
The present invention relates to a kind of plasma apparatus, the method that specifically a kind of automatic closing plasma screen shows.
Two, background technology
Television set is popularized, and TV reception has become the main leisure mode that people are in.Be that example illustrates the work relationship between plasma video and the audio frequency with the TV signal now.With the vision carrier frequency is 65.75MHZ, and sound carrier frequency is that the signal of 72.25MHZ is an example.The TV RF signals that obtains on the antenna and be input to the high-frequency tuning amplifier radiofrequency signal.Through high-frequency tuning amplifier amplification, frequency conversion, from frequency mixer output, the image intermediate frequency signal and first accompanying sound intermediate frequency signal that enter image intermediate frequency amplifier.This moment, the waveform envelope line did not change, and only carrier frequency is respectively 38MHZ and 31.5MHZ by 65.75MHZ and 72.25MHZ.
The image intermediate frequency signal of 38MHZ and 31.5MHZ, the 1st accompanying sound intermediate frequency signal after image intermediate frequency amplifier amplifies, are input to vision signal detector, demodulate vision signal and beat respectively and go out 6.5MHZ the 2nd accompanying sound intermediate frequency signal waveform.Vision signal encourages picture tube after amplifying.6.5MHZ the 2nd accompanying sound intermediate frequency signal is still frequency-modulated wave, puts reconciliation frequency device and demodulate audio signal in sound accompaniment, promotes speaker operation again after amplifying.
In the plasm TV, TV signal, AV signal, component/rgb signal, HDMI signal are handled back output by master chip at present.All signals all can be converted to vision signal and audio signal output after handling through master chip, and wherein audio-frequency module and video module separate, and audio signal accesses audio signal by chip solution and promotes loudspeaker work by independently audio chip processing.The video and the audio frequency of television set are exported substantially simultaneously, and promptly in audio frequency output, video must be opened, and Fig. 1 is seen in the inevitable display frame of screen.The maximum feature of prior art is exactly a whole of audiovisualization.Nowadays " energy-conservation " more and more becomes the topic that people pay close attention to, and also becomes the bright spot of various brands TV competition.The present display mode of plasma display system, see Fig. 2: opening power at first, screen display is opened; The master chip received signal is also handled, and wherein, with vision signal output, with audio signal output, at this moment, vision signal and audio signal were exported simultaneously after audio-frequency module was handled after video module was handled; Close, finish.
The shortcoming of existing plasma screen display packing is: display packing is single, can only be whole of audiovisualization, and not consider and look, listen intelligent pattern separately that the user must select audio signal when selecting vision signal, increase unnecessary electric energy loss, bring loss to the user.Because video and audio frequency are in running order for a long time, plasma screen short, damage easily in useful life.
Three, summary of the invention
The purpose of this invention is to provide the method that a kind of automatic closing plasma screen shows, this method has the function of intelligent power saving, television set increases " hearing enjoying " pattern, as long as switch to this pattern, screen display can be closed (state that is in no signal or blank screen) automatically, and audio signal can normally be exported, thereby reduces unnecessary energy loss.
The objective of the invention is to be achieved through the following technical solutions:
The method that a kind of automatic closing plasma screen shows is characterized in that it may further comprise the steps:
A) select signal to the plasma display system input pattern;
B) the master chip receptive pattern in the plasma display system is selected signal, and mode select signal carried out following processing: I) when mode select signal when only needing " hearing enjoying " pattern of audio-frequency function, master chip starts the hearing enjoying energy saver mode, video output signals is closed automatically, only output audio signal;
II) when mode select signal is general mode, master chip starts normal mode, and video output signals and audio signal are normally exported;
C) plasma screen receives the output signal of master chip, and shows.
Steps A of the present invention) in, can select signal to the plasma display system input pattern by the menu on the remote controller.
At step B) I) in, the energy-conservation screen display that is output as is no signal or blank screen state.
Plasma display system among the present invention can be a TV, also can be other display unit such as computer.
The present invention adopts and looks, listens intelligent pattern separately, it is available to have multiple display mode, and has a function of intelligent power saving, after television set increases " hearing enjoying " pattern, as long as switch to this pattern, screen display can be closed (state that is in no signal or blank screen) automatically, and audio signal can normally be exported, thereby reduces unnecessary energy loss; And, the plasma screen long service life.

Fig. 2 is the display mode flow chart of existing plasma display system;
Fig. 3 is the display mode flow chart of plasma display system of the present invention.
Five, embodiment
The method that a kind of automatic closing plasma screen of the present invention shows is considered as example with plasma electric, and it may further comprise the steps:
A) select signal by the menu on the remote controller to plasm TV display screen input pattern.
B) the master chip receptive pattern in the plasm TV is selected signal, and mode select signal carried out following processing: I) when mode select signal when only needing " hearing enjoying " pattern of audio-frequency function, master chip starts the hearing enjoying energy saver mode, video output signals is closed automatically, only output audio signal;
II) when mode select signal is general mode, master chip starts normal mode, and video output signals and audio signal are normally exported;
C) plasma screen receives the output signal of master chip, and the demonstration of being correlated with on request.When " hearing enjoying " pattern of selection, energy-conservation output, screen display is no signal or blank screen state.
Idiographic flow of the present invention is as follows:
Is menu → model selection (hearing enjoying pattern/general modfel) → hearing enjoying pattern opened? → to open the output of (withdrawing from) → video by acknowledgement key can close automatically by Menu key, screen display is no signal or blank screen state.
The present invention is to be benchmark with energy-conservation, and when the user only needed audio-frequency function, the switching by pattern can make screen display close, and so, not only can satisfy client's demand but also can save energy.
