Embodiment
Some exemplary embodiments that embody the utility model feature and advantage will be described in detail in the explanation of back segment.Be understood that the utility model can have various variations different in form, its neither disengaging scope of the present utility model, and explanation wherein and the accompanying drawing usefulness that ought explain in itself, but not in order to restriction the utility model.
See also the structural representation of Fig. 1 for the LCD TV with battery saving mode of the utility model preferred embodiment.The LCD TV that the utlity model has battery saving mode mainly comprises an image processor 20, an audio decoder 21, TV frequency variator 22, multimedia phonotape and videotape input interface 23 and a Liquid Crystal Module 24.
LCD TV has a plurality of audio-video signals source, wherein TV frequency variator 22 is a numeral or simulated television frequency modulator, a TV signal be can receive, cable TV signal and wireless television signal comprised, and with the TV signal demodulation that received and produce a picture signal and an audio signal.Another kind of audio-video signal source can be from various electronic multimedia products, for example Video Recorder, VCD player, DVD player, accompanying video, video camera or computer etc., these multimedia audio-video signals can receive via multimedia phonotape and videotape input interface 23, and export a picture signal and an audio signal respectively.
201 of the control units of image processor 20 are connected to this graphics processing unit 202, this audio decoder 21 and this Liquid Crystal Module 24, to carry out initializing set and Working mode set.In addition, this control unit 201 also can receive the external command signal that remote controller 30 sends through infrared receiver 31, or the external command signal that sends of the guidance panel of LCD TV 32, the selection of for example switching of channel, volume adjustment, TV or multimedia display, or the adjustment of screen color or the like.
The video picture principle of LCD TV is that the back light source system by liquid crystal panel carries out luminous, control the printing opacity degree of each pixel liquid crystal molecule again by drive circuit, with video picture on liquid crystal panel, wherein, the high pressure fluorescent tube of back light source system is to work by the high pressure that inverter produces.As shown in Figure 1, Liquid Crystal Module 24 comprises an inverter (inverter) 241, a liquid crystal panel 242 and one drive circuit 243.This Liquid Crystal Module 24 is powered by a power supply device 40, and convert the low-tension supply that power supply device 40 provides to high voltage source by this inverter 241, to drive the back light source system of liquid crystal panel 242, with lamp tube starting, and control its video picture on liquid crystal panel 242 according to the picture signal that the graphics processing unit 202 of image processor 20 sends by drive circuit 243.
The electric power system of tradition LCD TV all is to be whole openings, yet open TV only for background sound is provided the user, or just listen to the music or tin news, and when not needing to watch the image frame of TV, if the back light source system of liquid crystal panel still is held open state, will cause unnecessary power consumption, also can shorten the useful life of LCD TV.Therefore, LCD TV of the present utility model designs a switching circuit 41 between the inverter 241 of power supply device 40 and Liquid Crystal Module 24, and can or end by the conducting of these switching circuits 41 of control unit 201 control of image processor 20, whereby, when the user does not need to watch the image frame of TV, can transmit the control unit 201 that image processor 20 is arrived in the instruction of closing liquid crystal panel by remote controller 30 or guidance panel 32, control unit 201 is ended the switching circuit 41 between the inverter 241 of power supply device 40 and Liquid Crystal Module, power consumption when operating to reduce liquid crystal panel 242 reaches purpose of power saving.
Concerning the user, when it opens the power supply of LCD TV, the initial setting of switching circuit 41 is to present conducting state, therefore the user can watch the image of liquid crystal panel to play and listen to the audio signal that plays back via loudspeaker, yet, when the user does not need to watch the image broadcast of liquid crystal panel, then can press on remote controller 30 or the guidance panel 32 representative closes the function button of liquid crystal panel or selects via options menu, make LCD TV be in battery saving mode, reduce unnecessary power consumption.And when the user thinks to view and admire the image frame of TV again, then can arbitrarily press the button (volume is adjusted except the button) on remote controller 30 or the guidance panel 32, and can make switching circuit 41 conducting once more, reply the image playing function of liquid crystal panel 242.Therefore in operation, normal play mode and the switching of closing between the battery saving mode of liquid crystal panel are very easily.
In sum, the LCD TV that the utlity model has battery saving mode can be when the user need to view and admire the image frame of TV, the switching circuit that power supply device is powered to Liquid Crystal Module ends, to close the backlight lamp tube of liquid crystal panel, not only can significantly reduce the power consumption of LCD TV, more can increase the useful life of LCD TV.Therefore, the LCD TV that the utility model provides has industrial value, and meets all kinds of patents important document, thereby files an application in accordance with the law.
The utility model must be appointed by those of ordinary skills and executed that the craftsman thinks and be to modify the right neither determined protection range of the claim of enclosing that takes off as all.
