Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content.
Figure 1 illustrates the first embodiment of the present invention.
Fig. 1 is the realization flow 100 automatically lighting the method for mobile phone screen according to a first embodiment of the present invention, and details are as follows for this realization flow 100:
In step 110, obtain proximity state residing for mobile phone and screen state, simultaneously the change of detection of handset acceleration in vertical direction.
In a first embodiment, described proximity state comprises near state with away from state.Usually proximity transducer can be adopted to obtain the proximity state of object and mobile phone, wherein proximity transducer is generally infrared sensor, comprise an infrared transmitting tube and an infrared receiving tube, infrared receiving tube is used for receiving the infrared ray that reflects of infrared transmitting tube, when there being object near infrared sensor, infrared receiving tube will receive the infra-red intensity that infrared transmitting tube reflects, it is nearer that object leans on, the intensity reflected is larger, it is far away that object leans on, the intensity reflected is less, so the distance value between object and mobile phone can replace by infra-red intensity value therebetween.If the infra-red intensity between object and mobile phone exceedes certain set point, such as 1000, so think that object and mobile phone are near state; If the infra-red intensity between object and mobile phone is less than certain set point, such as 300, so think that object and mobile phone are away from state.
In a first embodiment, described screen state comprises horizontal screen state and perpendicular screen state.Usually acceleration transducer can be adopted to judge the state residing for mobile phone screen.Acceleration transducer is used for measuring current acceleration of gravity, mobile phone angle of inclination in vertical direction can be calculated by the component of acceleration of gravity on three-dimensional, when the angle of inclination calculated is in the first scope preset, judge that mobile phone is in perpendicular screen state; When the angle of inclination calculated is in the second scope preset, judge that mobile phone is in horizontal screen state, such as make mobile phone angle of inclination in vertical direction be a, when 0 °≤a≤45 ° or 135 °≤a≤225 ° or 315 °≤a≤360 °, think that mobile phone is in perpendicular screen state; As 45 ° of < a <, 135 ° or 225 ° < a < 315 °, think that mobile phone is in horizontal screen state.
Mobile phone acceleration change in vertical direction also can adopt acceleration transducer to measure, when mobile phone moves, corresponding acceleration change value can be produced at three-dimensional, such as when mobile phone is placed in pocket, it is generally acknowledged that mobile phone is near state, be in perpendicular screen state, if taken out from pocket by mobile phone, then mobile phone can produce corresponding acceleration change in vertical direction simultaneously.
In the step 120, the proximity state residing for mobile phone is near state, screen state be perpendicular screen state and the change of acceleration is more than the first acceleration change value in vertical direction time, automatically light mobile phone screen.
When the proximity state residing for mobile phone is near state, when screen state is for perpendicular screen state, open the interrupt mode of acceleration transducer, the condition presetting interruption is that mobile phone acceleration change is in vertical direction more than the first acceleration change value triggered interrupts.If when acceleration transducer now detects mobile phone acceleration change value in vertical direction more than the first acceleration change value, will triggered interrupts, automatically light screen simultaneously.Such as, when mobile phone is taken out from pocket, if when mobile phone acceleration change has in vertical direction exceeded the first acceleration change value preset, automatically mobile phone screen will be lighted, simultaneously displaying time, the date, with or without note, with or without information such as incoming calls, be illustrated in figure 2 the design sketch after automatically lighting mobile phone screen, in figure, 21 is common pocket, 22 mobile phone screens for lighting.
Preset value in the present invention can be set by handset manufacturers, and user also can be had to set, and also by handset manufacturers initialization, then can be changed by user.
The function automatically lighting mobile phone screen in the present invention by opening or open transducer to control, also can be established on & off switch to open or close this function on mobile phone.
The method that the embodiment of the present invention provides is by the proximity state of detection of handset, and screen state and mobile status, light mobile phone screen automatically, facilitate user check time on mobile phone screen, the date, with or without note, with or without information such as incoming calls.
Figure 3 illustrates the second embodiment of the present invention.
Fig. 3 is the realization flow 300 automatically lighting the method for mobile phone screen according to a second embodiment of the present invention, and details are as follows for this realization flow 300:
In the step 310, obtain proximity state residing for mobile phone and screen state, simultaneously the change of detection of handset acceleration in vertical direction.
In step 320, the proximity state residing for mobile phone is near state, screen state be perpendicular screen state and the change of acceleration is more than the first acceleration change value in vertical direction time, automatically light mobile phone screen.
In a step 330, after automatically lighting mobile phone screen, if detect that mobile phone acceleration change is in vertical direction more than the second acceleration change value, then automatic distinguishing mobile phone screen.
In a second embodiment, the step 310 of above-mentioned realization flow 300, step 320 and the corresponding step 110 in the first embodiment, step 120 are identical, do not repeat them here.
As can be seen from Figure 3, with the first embodiment unlike, add step 330 in a second embodiment.The second acceleration change value in step 330 is the value preset, this value can be worth identical with the first acceleration change, but the two direction is contrary, such as when in Fig. 2, mobile phone is put back in pocket again, an acceleration can be produced, the now change of mobile phone acceleration is contrary with the change of mobile phone acceleration when taking out in pocket, when this acceleration change value exceedes the acceleration change value preset, and will triggered interrupts automatic distinguishing mobile phone screen.
The embodiment of the present invention, by increasing the function of automatic distinguishing mobile phone screen, reduces mobile phone energy consumption, adds the convenience of mobile phone operation and intelligent.
