Lb, when a vertically downward inclination less than 20 degrees, the first sensor sensing 210 senses this situation, and the sensed result is transmitted to the sensor unit sensing operation. 接着,传感器动作感测部220将结果数据传送^^控制部230,控制部接收传感器动作感测部传送的结果数据,暂时关闭上述上部模块上的液晶显示屏的背光240电源。 Next, the operation of the sensor unit 220 senses the resultant data transfer control ^^ unit 230, the control unit receives the operation result data sensor sensing unit transmitted power is temporarily turn off the backlight 240 of the liquid crystal on the upper display panel module.

而且,在这种情况下,上述控制部230不〗又仅控制上述背光电源, 还可以控制能减少电池消耗电力的其他部分。 Further, in this case, the control unit 230 not only controls the backlight〗 and power, may also control other portions of the battery to reduce power consumption. 即,进入省电模式。 That is, power saving mode. 因此,当用户在使用上述便携式个人电脑的过程中,有其它要处理的事情时,将上部模块倾斜一定的角度,就可进入省电模式,可以实现最小耗电量。 Thus, when the user during use of the above-mentioned portable personal computers, there are other matters to be processed, the upper module is inclined at an angle, can enter the power saving mode, minimal power consumption can be realized. 然后,当上述上部模式120进入图lb的状态,即,关闭状态,进入完全关闭状态,如图lb所示,上述第2传感器212感测这一情况, 将感测到的结果传送给传感器动作感测部220,传感器动作感测部将结果数据传送给控制部230,控制部接收传感器动作感测部传送的结果数据,并完全关闭上述上部模块上的液晶显示屏的背光240电源。 Then, when the state of FIG. Lb enters the upper pattern 120, i.e., closed state into the fully closed state, as shown in FIG lb, the second sensor 212 senses this situation, the sensed result is transmitted to the motion sensor a sensing unit 220, a sensor unit sensing operation of the result data to the control unit 230, the control unit receives the operation result data sensor sensing transmission unit and the power completely turn off the backlight 240 of the liquid crystal on the display screen of the upper module. 但是,当上述上部模块120还原成如图la所示的最初使用状态而不是关闭状态时,第2传感器212感测这一情况,结果,控制部230 重新打开上述上部才莫块上的液晶显示屏的背光24G电源。 However, when the upper module 120 is reduced to the initial state of use shown in FIG. La is not closed, the second sensor 212 senses this case, the result, the control unit 230 re-open the upper liquid crystal display block only Mo the backlight power supply panel 24G. 图3是本发明中便携式个人电脑屏幕开关的第2实施例的构成框图。 FIG 3 is a block diagram of a second embodiment of the present invention, a portable personal computer screen switch. 参照图1和图3,对本发明中便携式个人电脑的屏幕开关的第2实施例的构成及动作详细说明如下。 Referring to FIGS. 1 and 3, a second embodiment of the present invention, a portable personal computer screen configuration and operation of the switch described in detail below. 如图3所示,本发明的第2实施例的便携式个人电脑的屏幕开关300包括以下部分:当上部模块120移动规定角度以上时,对其进行感测的传感器310;延时部320,输入上述传感器感测的结果数据,并接收输入信号,检查上述输入信号是否維持规定时间;传感器动作感测部330,接收上述传感器感测到的结果数据及维持时间,并对其进行存储;控制部340,接收从上述传感器动作感测部感测的结果数据及维持 3, the second embodiment of the portable personal computer screen switch 300 of the present invention comprises the following sections as shown: When the upper module 120 moves a predetermined angle or more, its sensing sensor 310; the delay unit 320, an input the sensor results sensed data, and to receive the input signal, checks whether the input signal is maintained for a predetermined time; 330, receives the result sensed by the sensor data and the sensor unit sensing operation duration, and stores them; and a control unit 340, receives the result data from the sensor unit sensing operation of the sense and maintain

时间,并对上述上部才莫块中的液晶显示屏背光350电源进行控制。 Time, and the upper block only Mo LCD backlight power supply 350 controlled. 这里,上述传感器310感测的上部模块120的移动角度是从最初状态倾斜70度以上的状态。 Here, the sensor 310 senses the movement of upper module 70 is not less than an angle of 120 degrees from the initial state inclined state. 即,如图la所示,假定上部模块120从打开状态向图lb之上部模块120关闭的状态移动,当垂直向下側倾斜70度以上时,上述传感器感测到这一情况,并将感测到的结果传送给延时部320。 That is, as shown in FIG. La, from the closed state to the open upper module 120 of FIG. Lb state assumed upper module 120 is moved, when the vertical downward inclined 70 degrees, the sensor senses this situation, and the sense the measured result is transmitted to the delay unit 320. 接着,延时部320接收上述传感器感测的结果数据,检查上述输入信号是否维持规定时间,具体是,检查上述上部模块120是否维持一定时间的规定角度即70度以上的倾斜状态。 Next, a delay unit 320 receives a sensing result of the sensor data, checking whether the input signal is maintained for a predetermined time, specifically, the upper module 120 checks whether a predetermined angle is maintained constant over time, i.e., 70 ° tilted state. 如果上述的检查结果是,上部模块维持了一定时间的特定角度倾斜状态,就认定用户要关闭上部模块120,将这一结果传送给传感器动作感测部330,而上述传感器动作感测部330将结果数据传送给控制部340,结果,控制部关闭上述上部模块上的液晶显示屏的背光350电源。 If the above test results, the upper module to maintain a specific angle of inclination state a certain time, it finds that the user wants to close the upper module 120, the sensor transmits the result to the motion sensing unit 330, and the sensor unit 330 senses operation result data to the control unit 340, a result, the power control unit 350 turns off the backlight on the liquid crystal display of the upper module. 但是,当上述上部模块120还原成图la所显示的最初使用状态而不是关闭状态时,即,当一定时间之前还原成上部模块打开的状态时, 通过控制部340重新打开上述上部模块上的液晶显示屏的背光350电源。 However, when the upper module 120 is reduced to FIG la shown initial state of use, rather than a closed state, i.e., when reduced to the upper module open state before the predetermined time, re-open the liquid crystal on the upper module by the control unit 340 350 power to the display backlight. 通过上述的说明内容,相关专业人员完全可以在不偏离本项发明技术思想的范围内,进行多样的变更以及修改。 The contents of the above description, related professionals can without departing from the scope of the technical ideas of the present inventions, a variety of changes and modifications. 因此,本项发明的技术性范围并不局限于说明书上的内容,必须要根据权利范围来确定其技术性范围。 Accordingly, the technical scope of the present invention is not limited to the content item on the instructions, which must be determined in accordance with the scope of the technical scope of the claim.
