The televisor that also has now has the function of multimedia card reader, can play digital audio files such as MP3, WMV.
Existing televisor had these enrich function when satisfying users on diversity, also have the some shortcomings part, such as, can not take into account the user and still can listen to the sound that televisor is play in the situation of not turning on display screen.When if the user only wants to listen to the sound that televisor plays, the display screen of also just having to open simultaneously, this has caused to a certain extent to the consumption of televisor hardware resource with to waste of electric energy.The backlight of display screen is the important power consumption parts in the televisor, is example with the LCD TV, and the power consumption of screen/display backlight accounts for major part in whole LCD TV, closes backlight and will save about 80% power consumption.
The utility model content
Technical problem to be solved in the utility model provides a kind of televisor that still can listen to sound when closing display screen.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
This televisor comprises display backlight source and the backlight driving unit that is used to drive the display backlight source,
Also comprise backlight control unit, be used to receive external signal and the unlatching by backlight driving unit control display screen backlight or close.
Described backlight control unit is that the described backlight driving unit of televisor central microprocessor is the backlight drive plate.
A general input/output port of central microprocessor is connected on the control pin of backlight drive plate.
Preferably, this televisor also comprises the storage unit that links to each other with described televisor central microprocessor, is used to store the unlatching of control display screen backlight or the control law of closing.
Preferably, this televisor also comprises the radio reception processing unit that links to each other with the televisor central microprocessor, is used for receiving and the playing frequency modulation broadcast program.
The signal that described external signal is the signal that sends of telepilot, the button on the TV set panel sent or be voice signal.
Described display screen is a LCDs.
Described televisor is a digital television.
Preferably, this televisor also comprises the network interface unit that links to each other with the televisor central microprocessor, is used to receive the multimedia messages of automatic network.
Preferably, this televisor also comprises the movable storage device interface unit that links to each other with the televisor central microprocessor, is used to read the multimedia messages on the movable storage device.
With open and close along with power switch, the conventional television that the backlight of display screen also can open and close is simultaneously compared, when using the utility model televisor TV reception, when only wanting to listen to sound if the user does not want to watch television image, then can send the signal of closing the display backlight source to backlight control unit, backlight control unit is then closed the display backlight source by backlight driving unit according to this signal, thereby display screen is quit work, so neither sound is listened in influence, can realize closing the purpose that display screen is beneficial to save electric energy and maintenance display screen again.
Description of drawings
Fig. 1 is the circuit structure block diagram of the colour television set of band FM radio in the prior art;
Fig. 2 is the control synoptic diagram in display backlight source in the utility model televisor;
Fig. 3 is the control synoptic diagram that the utility model has display backlight source in the televisor of function of radio receiver.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
The utility model aims to provide a kind of televisor that still can be by TV listening to audio program when display screen quits work, thereby makes this televisor have the function of freely listening.
As shown in Figure 2, the utility model televisor, comprise display backlight source 100 and be used to drive the backlight driving unit 200 in display backlight source, also comprise backlight control unit 300, be used to receive external signal and the unlatching by backlight driving unit control display screen backlight or close.
When the user uses the utility model televisor TV reception, if do not want to watch television image, and when only wanting to listen to the sound that television channel plays, then can open free auditory function, use a teleswitch or button or voice signal send the signal of closing the display backlight source to backlight control unit, backlight control unit is then closed the display backlight source by backlight driving unit according to this signal, display screen is quit work, so neither influence the user and listen to sound, display screen be can realize closing again and electric energy and maintenance display screen are beneficial to save, thereby realize the function freely listen, can reach the purpose of energy-conserving and environment-protective again, really accomplish green household electrical appliances.Otherwise, after backlight control unit receives the instruction of closing free auditory function, the display backlight source is opened by backlight driving unit, screen/display is started working.
Certainly, backlight control unit also can determine whether to open and close free auditory function according to other instruction that receives, close free auditory function when for example receiving an instruction of playing TV, open free auditory function when receiving the order of playing broadcasting, these can be set by user oneself, and corresponding rale store is got up with the action of control backlight control unit.
As shown in Figure 3, for making full use of the hardware resource that existing televisor itself is had, reduce production costs, described backlight control unit 300 is a televisor central microprocessor 301, and described backlight driving unit 200 is a backlight drive plate 201; A general input/output port (GPIO) of televisor central microprocessor 301 is connected on the control pin of backlight drive plate 201.Its control principle is: when turning on televisor, working properly after, the level of the GPIO mouth of central microprocessor control backlight drive plate is on high level, the screen/display backlight is opened.When the user selects free auditory function (for example by the button on the telepilot), at this moment the control signal sent of the corresponding GPIO mouth of televisor central microprocessor becomes low level, the screen/display backlight is closed, at this moment sound channel is still working on, and the user just can be as using walkman to use televisor.
