The first figure includes the panel of the display device ω of the computer system, and the system is a liquid crystal CD. Panel) 'The panel 1〇2 is based on the backlight of the display device (7):=_, and is the surface of the __ household_. When the computer system 1 is started, the backlight module (10) is driven by the light source, in the computer system 1 The object 2 ° in front of the display device *) * is the user of the computer system 1). The various information displayed on the panel 1 〇 2 can be seen from the display device 1 。. (4) (4) 1 After the start-up, it is often kept open for a long time; ',, display device 10 requires a backlight module 1〇 The backlight is continuously provided to the panel 102, so that the power consumed by the display device 10 accounts for most of the total power consumption of the entire computer system 1. However, according to the general usage habit, when the computer system 1 is turned on, the user has It takes a short time to leave the computer system i to the other place, and the time of leaving is not enough for the computer system 1 to save power, or to prompt the user to shut down the entire computer system. The user leaves the computer system 1 During this period, the backlight module 1〇 continues to supply a backlight source to make the panel 102 image, but the 201116988 user does not see the display device ί0, and the power consumed at this time. It is a waste of energy. The first pull, and the f set: use the computer system 1 to identify ί ^ = to reduce the display device 1G power 丨 _ effect, the younger one map does not, the action recognition device 12 is set in the display vouchers to identify its location The motion of the object 2 (ie, the user) within the detectable range is particularly the change in the motion of the user facing the display device; The device 12 includes a motion sensor (m〇ti〇nse, a heat sensor, a radar sensor (5) _ 褒, etc. When the user operates the computer system 1, it is necessary to continue to take = j In the process of knowing 'the operation of the computer system i, there are miscellaneous changes, even if only the web page can be smashed, there will still be fine movements such as turning, sideways or blinking. Therefore, the tongue recognition device 12 recognizes the user. When there is a change in action, it means that the computer system w is used where the computer system 1 is located, and the information that is displayed by == bit t J 1〇 is displayed. 'The controller 14 of the computer system 1 does not control the power saving of the device 10. 4 is not the right head, as shown in the second figure, when the user is away from the action recognition set 12, the _ temple, move: identify where: and recognize no change in the detection range, then control = set 12 Identifying the result of the identification device 12, controlling the display ° 曰 曰 according to the action into the mine #能, & 丨, ◦ backlight module 100: into the sorrow 'for example: reduce the backlight module 00 board 1 〇 2 dark, Or turn off the backlight · 1 〇〇 2 first redundancy to reduce the power of the display device 10 (four), to reach The backlight is output and the user's action is recognized again. The action is recognized and the backlight module is restored or turned on according to the recognition result. 201116988 The panel 102 is displayed on the panel 102. The user needs to be specially adjusted to leave the computer. When the system 1 is located, without any power state (P°WerState) of the aT system 1, or switching the light, the computer can automatically and immediately reduce the brightness or turn off the power consumption of the back or the H,, and ^ body. When the computer system 1 is like the first portable computer, the benefit of reducing the power consumption is also the power supply time and the service life of the battery of the computer. - The figure provides a more detailed computer system that can save electricity. The computer system 1a of this example includes a steamer 7|·^ ® 1 λ ^ having a backlight module 100 and a panel] 02, a device 1 〇, a motion sensor 12a, a controller 14a, and a peripheral device 16 and a pulse unit 18. The motion sensor 12& is the motion recognition of the motion change of the body (such as the computer system 1a), which can detect when the user operates the computer system 1& Change, _ device (4) includes a meter The unit 14 is, for example, seen in the PWH^· dhdQgtimei<) circuit cake control (4) 14& in the time program; the timing unit 14 is timed according to a predetermined time. The controller (4) is remotely permeable to the universal output pin (Gpi〇) Or a bus bar to connect and control the peripheral device 1 $ such as a keyboard or mouse of '4 1 a', and a pulse unit that controls the computer system la to generate or stop the clock. In an embodiment, the controller 14a may be an embedded controller (Embedded Ccmtroller). The motion sensor 12a may be disposed on the top of the display device 1 以 as shown in the first figure to detect the user's face or upper body movement, or set in the computer. Any function of the system la can detect the action of the user when operating the computer system la. When the computer system 1a is maintained in the activated state, the motion sensor 12a continuously or periodically senses the displacement of each object within the detection range, and determines whether the user has an action change according to the result of the sensing, for example, lifting 201116988; low hand, etc., to identify whether the user is using the computer system = the sensing range of the detector 12a can limit the display of the background matter of the vehicle, such as a certain distance of the vehicle. 'In order to accurately identify the current operation of the electricity = measurement" 7 12a according to the sensing result 'with or without identifying the object will output a sensing signal to the controller (4) out of the sensing range, the occurrence of action changes, you can know the user The result of the operation of the computer system is transmitted. _ Measured city, that is, the AL action sensation 123 is determined according to the discrimination. At this time, the control ===== one coffee) The sensing range of the motion sensor 12a is removed.

Closed state. Each time the motion signal is received, the timing unit will be re-timed. For example, the timing unit 40 will re-count from zero to zero after receiving the motion signal every time (or from zero to zero) The nth second). When the user is operating the computer system 12, the sense of motion will be sent to the controller 14a, and the controller Ma will reset the timer =! 40 so that the time cannot be accumulated to the predetermined number of seconds. , the controller (4) J = will make the backlight module 00 enter the power-saving state, the display device 1 〇 can normally use the backlight source provided by the backlight module (4) 0 on the panel 1 〇 2 as the motion sensor 】 2a sends a non-action signal to Controller ^, time: Yuan:: new timing 'but '_ Resignation - 1 / 1 Λ Ί 4a consecutively connected to the non-action signal, and the accumulated time of the second T has reached the scheduled time (such as above) N seconds) There is already a motion of the object that has not been detected. It should be displayed that the station has left the operating range of the computer system for a period of time Η〇6, by reducing the supply of the deer 拴 拴 拴 a 4a The measure of the pulse width of the electric device is shortened, the voltage of the backlight module is just turned on or the backlight source is lighted. The backlight is used to reduce the brightness of the backlight source, or the display is suspended for less display, and the light source is turned off. In order to achieve the reduction in the startup state, effectively reduce the computer system la =:== backlight to save power, because the user system la is not connected to other devices, so you can further save power to the computer to save the user's operating instructions and idle devices The 14a can also control the power of the clock. In this embodiment, the controller 7018 or the peripheral device 16 of the 201116988 is connected to the controller 14a via the bus bar. The method of implementation is, for example, up to N seconds (that is, the 杲 积 & & 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 The foot sends a control signal to the backlight module 1 (8), so that the backlight core group 1GG enters a power saving state; and then the second predetermined time is turned over, for example

If it is moved again, that is, the time after the non-action signal is received (N+M) t, the right signal is not received to trigger the timing unit to re-time, and the control 11 14a disables the keyboard. The mouse or the joystick is set to 16 to reduce the power consumed by the peripheral device 16 in standby: the right reaches the first: the predetermined time, for example, another p seconds, so that the non-action signal (four) is received for a long time (N misp After the second, the controller 14a directly sends the control signal R or the gate control to provide the clock power of the engine clock of the engine. The power consumed by the tiger is output, so that the computer system la enters. Hardware away mode (HardwareAway M〇de). By gradually following the second time of the above-mentioned second time, after the first scheduled time, and after the third predetermined time and after the first day of the first day, the power consumption of the computer system la is gradually reduced. The power of the computer system is saved efficiently. When the backlight module 100 is in the power saving state, if the motion sensor 12a sends the motion signal to the controller 14a again, the controller 14a causes the timing unit H0 to re-time and stops executing. The power saving measure includes controlling the backlight module 100 to leave the power saving state, returning to the backlight brightness before entering the power saving state, or re-circulating the backlight source, enabling the peripheral device 16 to be operated by the user, and restarting. The clock unit 18 restores the output of the clock signal, thereby allowing the user to return to the computer system la or the display device 1 before the celebrity, % continued operation, the computer system la can be instantly restored to the user before leaving: 201116988 Status 'For the user to operate smoothly. The motion recognition device in this embodiment is based on the motion sensor 2a' but can also be a heat sensor or The radar sensor replaces the motion sensor i2a to achieve the same effect. The radar sensor applies the principle of the Doppler Effect: sensing the frequency of the sound of the object being sensed by crying. The distance between the sensor and the object is inversely proportional; according to the reflection frequency received by the radar sensor, the distance between the sensor and the object can be calculated, so that the object (user) is close to or away from the computer system in the computer system la The movement changes, and whether the user moves away from the computer system to beyond the detection range, and then sends the action signal or the non-motion signal. The thermal sensor can be emitted according to the heat radiated by the object, especially the body parts and body temperature. Different thermal radiation (infrared), when the two bodies of the human body produce different actions, the thermal sensor will sense the movement of the thermal Han's to identify the motion change of the object to send the motion signal; The non-action signal is reversed when the radiation changes (that is, the motion change is not sensed).

The fourth figure provides a block diagram of a second embodiment of a computer system that can save power, and a schematic diagram of a second embodiment shown in the fifth diagram of the month-and-white. The second of this example has a display device and a host 19 to which it is connected. The image manipulation device (3) that is not set as the motion recognition purple is displayed as a % optical mode pass 100, panel 1〇2, and backlight logic control. The backlight logic controller tearing system is used to drive the backlight module (10), for example, the voltage is supplied to make the backlight source emit light, and the control unit is called the control unit, except for the timing unit, which is called the camera unit (4). The device 12b includes the image manipulation module 12 〇 = 12 201116988 Alignment module 122, paste video recording - in order to identify whether the user has a change in motion. The image capturing device Ub, such as a video camera disposed on the display device 103, captures the image in the shooting range by the image capturing module 120 at a high time, for example, every second - The image matching module m sequentially compares the latest valleys of the two images to determine whether the image is changed. If the comparison results show that the image content is different, it indicates that the captured object has an action change, and the image is compared.

In this example, although the image capture device (3) y ang illuminate no - the technical field of people 201116988 In the embodiment, the motion recognition device and other motion recognition devices are used to achieve the phase effect. Thus, when the user is not located at the computer system lb, the backlight logic can be turned off or lowered. The manner of backlight brightness saves power consumed by the display device 10. The difference between the present embodiment and the first embodiment is that the display device 10a shown in the fourth and fifth figures can be controlled by the backlight logic controller 14b. The backlight module passes through 100, and does not need to pass through the k-made unit in the host a (such as the above-mentioned controller) to control or judge the backlight source of the panel 2 ^. When the display device IGa does not display the surface, the electric moon is still 'd~ The first work of lb is still in the _ On the machine 19, as usual, such as slot sharing, data transmission, data calculation, etc., the smoothness of the user's use of the computer music system lb is not affected. & one Z, Figure 7, seven computer system power saving method implementation The flow chart of the example, the schematic diagram shown in the figure.

To S3G7)...Magnetic (10) continues to be in the seventh figure and then provides a computer system power saving method. More specific embodiments of the method, please - and refer to the block diagram shown in the third figure. First, the system 1 & After the startup, the display device 1 starts to display the backlight according to the backlight module 100, and displays the computer system and system on the panel 102. The surface is presented (S501); then, as the motion recognition device (4), the motion of the object within the sensing range is sensed. For example, (4) is used to identify whether the user has an action change, and the root-sensing-sensing-sensing Signal (S503) 'The sensing signal includes the action signal and the benefit = Shouyin 201116988. If the motion sensor 2a recognizes that the user has a motion change, it sends an action signal to the controller 〖4a (S505), The controller Ma includes a timing unit 14 for timing according to a predetermined time set in advance. When the controller Ma receives the action signal, the timing unit 14 causes the timing unit 14 to recalculate the predetermined time (§507). For example, the watchdog circuit is reset. Then, the process returns to step S501, and the display device is held in the state of the backlight display screen to continue the process of step S501 and below. In step S503, the object is detected (in this example) That is, the user's action, and recognize that the user has no action change, the motion sensor 12a sends a no action signal to the controller 14a (S509), at this time, the controller 'A does not make the leaf time unit 140 Renew The time is calculated, but it is judged whether or not the accumulated time length of the timing unit 14 has reached the predetermined time (S5U): if the predetermined time has not yet arrived, the process returns to step S501 to cause the display device 1 to maintain the state of display = for the user to watch. However, since the timing unit M0 continues to accumulate the elapsed time (S515) because it is not re-timed in step S5U. On the other hand, if it is judged in the step continent that the counting unit 14〇 has accumulated, it has already reached _longding_ When the controller 14a sends a control signal to the moonlight group 100' to bring the backlight module 100 into a power-saving state (S513), the brightness side (4) 1 of the backlight is lowered, and the power consumed by f1() is displayed as a money. While the backlight module 100 is in the power saving state, the motion sensor 12a will continue to recognize the user's motion change (eg, step s5〇3), so that when the user returns to the computer system la where the computer system ia is operated, The controller Ha can receive the action signal sent by the motion sensor '12a (s5〇5)=re-clocking the timing unit 14〇 (S507), and the backlight module 1〇〇 is left in the power-saving state, that is, the original is restored.
