Description
The present invention relates to a kind of image display system, relate in particular to a kind of image display system that utilizes infrared inspector for saving consumption electric power.
Usually all be provided with electricity saver in the present computer equipment, the power supply that is used to avoid unnecessary is wasted, a kind of the most frequently used electricity saver is to utilize a supervisory programme to monitor the user mode of each input media, and comes the power supply output of controlling computer to reach purpose of power saving according to the result who monitors.The control principle of supervisory programme institute foundation is: if do not use any input media a period of time user, this expression user may leave computer or not need to use computer at present, therefore just the partial circuit of computer can be closed or make it to enter wait (standby) state to save power supply.If do not use any input media yet through user after a while again, then supervisory programme can make computer advance one one and enter time-out (suspend) state.At last, if do not use any input media yet through one section long time user, then supervisory programme is closed computer (off).When the user began to touch a certain input media again, electricity saver can revert to user mode with computer.Recovering the needed time need decide on the state before recovering, and normally time-out is of a specified duration more, and needed release time is also just long more.
The advantage of this known electricity saver is the user mode of the automatic monitoring computer of its meeting and handles it to reach purpose of power saving that still this control method also has very big shortcoming.When the user left computer, supervisory programme need just can be made a response through after a certain default stand-by period, and this makes many electric power be wasted in the wait process.As desire to avoid the generation of this situation, the default stand-by period just essential the shortening, can cause bigger puzzlement to the user yet shorten the stand-by period.The user in the process of using, if take a quick nap or pause, just might make supervisory programme with partial circuit for example monitor display screen turn off, this makes the user can't continue to see display screen.Display screen just can revert to user mode after the user must remove to touch key or mouse, and this causes very big interference to the user.
Fundamental purpose of the present invention is to provide a kind of image display system that utilizes infrared detector to save the power supply supply, to address the above problem.This image display system is provided with an infrared detector, is used to detect the user who is positioned at before the image display system.When the user left image display system, this display device can enter power down mode immediately; And when the user returned, this display device can be recovered user mode at once, so the user does not need to do any action and comes recovery system.
The object of the present invention is achieved like this, and a kind of image display system promptly is provided, and it includes: a display circuit is used for the display image picture; One power circuit is used for controlling according to a power control signal power supply supply of described display circuit; One infrared detector is used to detect and is positioned at the user before the described image display system and produces the relevant detection signal; And a control circuit, it is electrically connected on described infrared detector, is used for producing corresponding power control signal according to the detection signal that described infrared detector produced, to control the power supply supply of described power circuit to described display circuit.
Describe the present invention and advantage thereof in detail below in conjunction with the accompanying drawing illustrated embodiment, wherein
Fig. 1 is the external view of image display system of the present invention;
Fig. 2 is the calcspar of Fig. 1 image display system;
Fig. 3 is another embodiment of image display system of the present invention;
Fig. 4 is the calcspar of Fig. 3 image display system.
Please refer to Fig. 1, Fig. 1 is the external view of image display system 10 of the present invention.Image display system 10 includes a shell 18, one display screen 12 is located at the front end of shell 18 towards the user, be used for the display image picture, one infrared detector 14 is located at the front end of shell 18, be used to detect the user who is positioned at before the image display system 10, and a plurality of control knobs 16, be used to control brightness, contrast and the switch of image display system 10.
Please refer to Fig. 2, Fig. 2 is the calcspar of Fig. 1 image display system 10.System 10 includes a display circuit 20, be used for the display image picture, one power circuit 28, be used for controlling the power supply supply of display circuit 20 according to a power control signal, one infrared detector 14, be used to detect the user before the system of being positioned at 10 and produce the relevant detection signal, an and control circuit 22, it is connected in power circuit 28 and infrared detector 14, be used for producing corresponding power control signal, with the power supply supply of 28 pairs of display circuits 20 of control power circuit according to the detection signal that infrared detector 14 is produced.Control circuit 22 is controlled the power supply supply of 28 pairs of display circuits 20 of power circuit according to a default power-saving control pattern, this control model can be as above-mentioned known electricity saver, lowers the power supply supply to reach purpose of power saving according to the length of stand-by period.
Please refer to Fig. 3, Fig. 3 is another embodiment of image display system of the present invention.Image display system 50 is a computer system, it includes a shell 58, one display screen 52 is connected in the rear end of shell 58 in rotating mode, be used for the display image picture, one infrared detector 54 is located at the front end of shell 58 towards the user, is used to detect the user who is positioned at before the computer system 50, and a CD drive subsystem 74 is used for playing CD, and several control knobs 56, be used for brightness, contrast and the switch of controlling computer system 50.
Please refer to Fig. 4, Fig. 4 is the calcspar of Fig. 3 computer system 50.System 50 includes a display circuit 60, be used for the display image picture, one power circuit 68, be used for controlling the power supply supply of display circuit 60 according to a power control signal, one infrared detector 54, be used for detecting and be positioned at the user before the computer system 50 and produce the relevant detection signal, one Winchester disk drive subsystem 70, be used for storing data, one Winchester disk drive power circuit 72, be used for controlling the power supply supply of Winchester disk drive 70 according to a power control signal, one CD drive subsystem 74, be used to play CD, one CD-ROM drive power circuit 76 is used for a power supply supply according to power control signal control CD drive 74 and a control circuit 62, it is electrically connected on infrared detector 54, is used for producing corresponding power control signal to control each power circuit 68 according to the detection signal that infrared detector 54 is produced, 72 and 76 power supply supplies to each corresponding subsystem.
Whether control circuit 62 is positioned at before the computer system 50 except understanding the user according to the detection signal that infrared detector 54 produces, and determine whether start outside the power-saving control with this, also can cooperate known electricity saver, determine whether starting power-saving control according to the user mode of the input media of computer system 50.In this case, the power-saving control pattern of computer system 50 can be set up according to two kinds of situations, and a kind of person of being to use is the situation before computer system 50 not, the another kind of then situation of the person of being to use before computer system 50.The power-saving control pattern of being set up in both cases, all more effective and reduce the inconvenience that the user is caused because of actual power-saving control more than the power-saving control pattern of known electricity saver, because whether control circuit 62 can very clearly be known the user is before computer system 50, and can only make a decision according to the user mode of input media unlike known electricity saver.
