For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.In conjunction with the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
Embodiments of the invention 1 provide a kind of method regulating display backlight in conjunction with acceleration transducer, be intended to solve when mobile terminal angle of inclination changes, avoid optical sensor to judge current environment light intensity by accident to change, thus the backlight illumination of mistuning joint display screen, cause the problem that display screen glimmers.Below in conjunction with accompanying drawing, the present embodiment is described in detail.
Fig. 1 is the schematic flow sheet of the embodiment of the present invention 1, please refer to Fig. 1, and the method for the present embodiment comprises the following steps:
S1, when mobile terminal receives bright screen request, start optical sensor, optical sensor gathers current ambient light intensity (being set to X) by the light well that mobile terminal is provided with, and the ambient light intensity X collected is uploaded to application layer; After application layer receives ambient light intensity X, the request of response bright screen, and regulate the corresponding backlight illumination of display screen according to this ambient light intensity X; Also perform step S2 simultaneously;
In the android system of mobile terminal, the framework of sensor is application layer, hardware device level and driving layer from top to bottom successively, the data of optical sensor and acceleration transducer are all obtain at driving layer, then successively to upper layer transfers, are finally delivered to application layer and process.Such as, ambient light intensity is uploaded to application layer after collecting current environment light intensity by optical sensor, and application layer environmentally light intensity processes display backlight brightness.And the inclination angle value of mobile terminal also carries out computing acquisition in application layer.
As the preferred scheme of one, in described mobile terminal, preset the corresponding relation of ambient light intensity and backlight illumination, in the terminal built-in before the corresponding relation of described ambient light intensity and backlight illumination dispatches from the factory.When current ambient light intensity X is uploaded to application layer by optical sensor, when application layer receives ambient light intensity X, just set according to the display screen of backlight illumination to mobile terminal corresponding with it arranged when dispatching from the factory.User is made to read soft, not dazzling and reach the object of saving power supply in order to allow.When ambient light intensity is more weak, the backlight illumination of display screen should be adjusted to reduced levels, and when ambient light intensity is stronger, the backlight illumination of display screen should be adjusted to higher level.
S2, unlatching acceleration transducer, and the angle of inclination A of current mobile terminal is detected by acceleration transducer;
Preferably, described acceleration transducer is 3-axis acceleration sensor; The detailed process that described acceleration transducer detects current mobile terminal angle of inclination is as follows:
Acceleration transducer detects acceleration of gravity in X-axis, three axle component size of Y-axis and Z axis, and according to acceleration of gravity in X-axis, the component size of Y-axis and Z axis calculates the angle of inclination of mobile terminal.
Direction vector due to acceleration of gravity must be vertically downward, and the value of acceleration of gravity constant be 9.8, as long as therefore learn that acceleration of gravity is in X-axis, the component on Y-axis and Z axis, just can calculate the angle of inclination of current mobile terminal.
At this, be described for mobile phone: the direction vector due to acceleration of gravity must be vertically downward, and the value of acceleration of gravity constant be 9.8, therefore, when mobile phone is in the state of vertical horizontal screen, the Z axis value of acceleration of gravity is 9.8, X-axis value is 0, and Y-axis value is also 0.
And when mobile phone is in heeling condition, acceleration of gravity vertically downward in X-axis, Y-axis and Z axis three spatial axes will all exist component, angle of inclination is different, and three axle components are also different.The angle of inclination of described mobile phone calculates according to acceleration of gravity component size on three axles to be determined.
Such as when mobile phone is in the horizontal screen state of Right vertical, the angle of inclination of mobile phone is 90 degree, and when mobile phone is in the horizontal screen state of left vertical, the angle of inclination of mobile phone is 270 degree.And when mobile phone is in vertical perpendicular screen state, the angle of inclination of mobile phone is 0 degree or 360 degree.
Inevitable, under display screen is in bright screen state, described optical sensor continues to gather current ambient light intensity, and judges whether current environment light intensity changes, and is judged as NO, then continue to gather, be judged as YES, then enter step S3;
S3, when described optical sensor collect ambient light intensity change time, if when ambient light intensity becomes Y from X, first do not upload new ambient light intensity Y, first, detected the angle of inclination B of now mobile terminal by acceleration transducer, and judge whether the difference between angle of inclination A and angle of inclination B is greater than the angle threshold of setting; Be judged as YES, then perform step S4, be judged as NO, then perform step S5;
As the preferred scheme of one, described angle threshold values is 15 degree.
Certainly, in actual applications, described angle threshold values can also be other values, and different mobile terminal threshold values is also different, specifically can optionally set.Certainly, also can change the angle threshold values of setting.The present embodiment only provides a preferred angle threshold values.
S4, explanation mobile terminal, still in the environment of former ambient light intensity X, are cancelled and are uploaded new ambient light intensity Y, because now application layer does not receive new ambient light intensity, therefore maintain the original backlight illumination of display screen;
Residing for S5, explanation mobile terminal, the ambient light intensity of environment there occurs change, and new ambient light intensity Y is uploaded to application layer by optical sensor, after application layer receives new ambient light intensity Y, readjusts the backlight illumination of display screen according to this ambient light intensity Y.
For the ease of understanding, the backlight illumination arranging display screen during to dispatch from the factory is the mobile phone of six increased brightness grades, is described.Such as, arranging backlight illumination when mobile phone dispatches from the factory is: six of 10% brightness degree, 20% brightness degree, 30% brightness degree, 50% brightness degree, 70% brightness degree and 100% brightness degree increase progressively grade.And when dispatching from the factory, being also provided with brightness degree corresponding to different ambient light intensities simultaneously, the angle threshold values of mobile phone is 15 degree.Be described for practical application below:
Table 1 is the ambient light intensity of setting when mobile phone dispatches from the factory and the corresponding relation (certainly only illustrate here, different mobile terminals and different optical sensors are arranged all can be different) of backlight illumination.
| Ambient light intensity | Backlight illumination |
| Be less than 30 | 10% brightness degree |
| 30～300 | 20% brightness degree |
| 300～800 | 30% brightness degree |
| 800～2500 | 50% brightness degree |
| 2500～5500 | 70% brightness degree |
| More than 5500 | 100% brightness degree |
Table 1
Such as: current ambient light intensity is 200, the backlight lightening of display screen is 20% brightness degree.Detected the angle of inclination A of current mobile terminal by acceleration transducer simultaneously.
When optical sensor collect current ambient light intensity become 500 time, first do not upload this ambient light intensity, but first Negotiation speed sensor detects the angle of inclination B of current mobile terminal; And judge whether the difference between angle of inclination A and angle of inclination B is greater than 15 degree.
Such as, if the difference between angle of inclination A and angle of inclination B is 40 degree, then judge it is because the difference at mobile phone angle of inclination causes the light intensity entering light well to add, but the ambient light intensity of reality does not change.Such as, it may be the change due to mobile phone angle of inclination, the lightlng hole on mobile phone is caused to face light source, under the reason of light source direct projection lightlng hole, current environment light is 500 to cause optical sensor to be thought by mistake, but, when mobile phone pendulum with after going back to original much the same position, ambient light sensor is inevitable thinks that again current environment light intensity becomes 200 from 500 by mistake, thus the backlight illumination of high-frequency mistuning mobile phone display screen, cause display screen to glimmer.And in the present invention, now should cancel and upload new ambient light intensity 500, application layer, owing to not receiving new ambient light intensity 500, therefore maintains existing 20% brightness degree of mobile phone display screen, the effective problem solving display screen flicker.
If the difference between angle of inclination A and angle of inclination B is 10 degree, then judge that current ambient light intensity changes, ambient light intensity becomes 500 from 200, new ambient light intensity 500 is reported to application layer by optical sensor, after application layer receives new ambient light intensity 500, the backlight illumination regulating mobile phone display screen is 30% brightness degree.Wherein, the value of above-mentioned ambient light intensity is the data value directly read out inside the register of ambient light sensor.
