[embodiment]
See also Fig. 3 and Fig. 4, Fig. 3 is positioned over the synoptic diagram on a plane 40 for portable computer 30 of the present invention.Fig. 4 is the functional block diagram of the portable computer 30 of Fig. 3.Portable computer 30 includes a housing 11, a display panel 12, a direction-control apparatus 14, a microcontroller 34 and a gravity sensor (G sensor) 32.Display panel 12 is to be installed on the housing 11, is used for show image.Direction-control apparatus 14 is to be used for producing direction signal.Gravity sensor 32 is to be installed in the housing 11.Direction-control apparatus 14 can be four directionkeys that are installed on the housing 11, or is connected in the rocking bar or the trace ball (track ball) of the Port of being located on the housing 11 36.
See also Fig. 5 and Fig. 6, Fig. 5 is the functional block diagram of the gravity sensor 32 of Fig. 4, and Fig. 6 is the sequential chart of the output voltage of gravity sensor 32.Gravity sensor 32 comprises an x sensor 60, a y sensor 62, an oscillator (oscillator) 64, two phase demodulation power transformation road 66, a work period modulation circuit (duty cycle modulator) 68.Oscillator 64 is the signal that is used for producing phase phasic difference 90 degree.X sensor 60 and y sensor 62 are used for the inclined degree of sensing x component and y component respectively, and according to the square wave of inclined degree output various amplitude.66 on the phase demodulating power transformation road that is electrically connected on x sensor 60 and y sensor 62 respectively is used for this output square wave of rectification.Through work period modulation circuit 68 signal transition after the rectification is become a square-wave signal with different operating cycle at last, as shown in Figure 6.Work period is the angle of inclination Ф of 50% square wave (that is T1/T2=0.5 of Fig. 6) expression X sensor, 60 sensings
xBe 0 degree, or the angle of inclination Ф of Y sensor 62 sensings
yBe 90 degree.When x sensor 60 or y sensor 62 sense when tilting to take place, will make work period modulation circuit 68 by output terminal X
Out, Y
OutThe work period of output voltage (duty cycle) changes thereupon.
Because display panel 12 can tilt along with the inclination of gravity sensor 32, so in fact, the angle of inclination of gravity sensor 32 just can determine the angle of inclination of display panel 12.Aforementioned mentioning, gravity sensor 32 can be according to the output voltage in different inclined degree output different operating cycles, so microcontroller 34 can be judged the angle of inclination of display panel 12 according to the work period of different output voltages.
See also Fig. 7 to Figure 10, Fig. 7 to Figure 10 is the portable computer 30 of Fig. 3 when favouring different angles, the synoptic diagram of the deviation angle of 32 sensings of gravity sensor.Suppose that portable computer 30 is to be positioned over (as shown in Figure 7) on the plane 40 at the beginning, at this moment the angle of inclination Ф of X sensor 60 sensings of gravity sensor 32
xBe+90 degree, the angle of inclination Ф of Y sensor 62 sensings
yBe 0 degree (that is level), this moment, display panel 12 was the image 50 (being letter C AT) that shows according to first pattern.Next, rotate the state of portable computer 30 to Fig. 8, can find the angle of inclination Ф of X sensor 60 sensings of gravity sensor 32 from Fig. 8
xBe-90 degree, the angle of inclination Ф of Y sensor 62 sensings
yIt is 0 degree (level).And gravity sensor 32 can be because Ф
xThe change at angle of inclination and export the output voltage in different operating cycle.Microcontroller 34 can be judged the angle of inclination of display panel 12 according to the work period of this output voltage, and adjusts the direction of display panel 12 show images.Microcontroller 34 also can be adjusted the direction signal that direction-control apparatus 14 produces according to the direction of display panel 12 show images.For instance, the display panel 12 of portable computer 30 triggers when the state of Fig. 7 " Left " during key, can export the direction signal that a control picture moves towards direction 101, trigger " Right ", can export a control picture towards direction signal in contrast to direction 101.But when forwarding portable computer 30 state of Fig. 8 to, the same triggering " Left " key, can export a control picture towards the direction signal that moves in contrast to direction 101, trigger " Right ", can export the direction signal of a control picture towards direction 101.In like manner when Fig. 9, the angle of inclination Ф of X sensor 60 sensings of gravity sensor 32
xBe 0 degree (level), the angle of inclination Ф of Y sensor 62 sensings
yBe+45 degree.In Figure 10, the angle of inclination Ф of X sensor 60 sensings of gravity sensor 32
xBe 0 degree (level), the angle of inclination Ф of Y sensor 62 sensings
yBe-45 degree.And microcontroller 34 just can sense angle of inclination Ф according to gravity sensor 32
xWith angle of inclination Ф
yJudge the angle of inclination of display panel 12, and then adjust the direction of display panel 12 show images and the direction signal that direction-control apparatus 14 produces.
In simple terms, the portable computer 30 of present embodiment can define four kinds of control models, each control model system represents display panel 12 respectively respectively with four kinds of orthogonal direction show images, and the controlling party of the direction signal of direction-control apparatus 14 is to being the direction that corresponds respectively to display panel 12 show images.For instance, suppose to set portable computer 30 put as shown in Figure 7 the time, and its angle of inclination Ф
xTransformation is set display panel 32 with the first control model show image between between 0 degree and+90 degree time, that is to say, the direction of display panel 32 show images as shown in Figure 7, the direction signal of direction-control apparatus 14 generations this moment is also corresponding to first control model.Once angle of inclination Ф
xTransformation is between 0 degree is spent with-90 the time, microcontroller 34 can be with one second control model that is set at of portable computer 30, under the second control model situation, the direction signal that the direction of display panel 32 show images and direction-control apparatus 14 produce is all in contrast to first control model.In like manner, once angle of inclination Ф
yFor+90 spend to 0 the degree between the time, microcontroller 34 can be set display panel 32 all with the 3rd control model show image, that is to say, the direction of display panel 32 show images as shown in Figure 9, and the direction signal that direction-control apparatus 14 produces is also corresponding to the 3rd control model.Once angle of inclination Ф
yBe 0 spend-90 the degree between the time, microcontroller 34 can be set display panel 32 all with the 4th control model show image, under the 4th control model situation, the direction signal that the direction of display panel 32 show images and direction-control apparatus 14 produce is all in contrast to the 3rd control model.
Note that needs great angle of inclination Ф
xOr angle of inclination Ф
yJust needing the switching controls pattern is to determine according to deviser's needs.
Compared to known techniques, the gravity sensor of portable computer of the present invention can be exported a sensing voltage according to the angle of inclination of display panel.Microcontroller can be adjusted the direction of display panel show image according to the size of this sensing voltage, and adjusts the direction of this display panel show image according to this microcontroller, adjusts the direction signal that this direction-control apparatus produces.In such event, the user when using portable computer, the angle of inclination of conversion display panel arbitrarily just, and needn't worry display panel inharmonious when show image.
The above only is embodiments of the invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to the covering scope of patent of the present invention.
