Wake up.
Fig. 7 is the flowchart 2 of the control method of backlight illumination according to the preferred embodiment of the invention, as described in Figure 7, and should
Method comprises the following steps:
S702, under LCD backlight automatic brightness adjustment pattern, user opens backlight and arranges abnormity prompt function.
S704, whether ambient light sensor detection ambient light light intensity S1 meets the ring that current LCD backlight light intensity P0 is corresponding
Border light light intensity S0 ± Δ S0th.If it is, do not perform any operation；If S1 > S0+ is Δ S0th, then according to automatic mold
Formula increases LCD backlight brightness, LCD backlight light intensity P1 that regulation to ambient light S1 is corresponding；If S1 < S0-is Δ S0th
Then perform S706.
Wherein S0 represents the intermediate value of LCD backlight light intensity P0 correspondence ambient light range of light intensity；Δ S0th represents, environment
When light light intensity Sx meets S0-Δ S0th < Sx < S0+ Δ S0th, the LCD backlight light intensity being automatically adjusted under pattern be P0 and
Will not change with Sx.
S706, mobile phone open proximity transducer, it may be judged whether have object close, namely determine whether that object blocks ring
Border optical sensor.If otherwise reducing LCD backlight brightness, the LCD that regulation to ambient light S1 is corresponding according to automatic mode
Backlight light intensity P1；If it is S708 is performed.
S708, it may be judged whether be special scenes application need and this occurs.If (such as earpiece call
Pattern), then perform corresponding scene operation.If it is not, then perform S710.
S710, ejects prompting frame, reminds user's light proximity transducer to block, and/or provides user and operate boundary further
Face.User such as can be allowed to select automatically not adjust LCD backlight light intensity according to automatic mode and still use LCD backlight light
Strong P0, or select automatically to adjust LCD backlight light intensity to LCD backlight corresponding to ambient light S1 detected after blocking
Light intensity P1, or no longer block action prompt etc. for this.
S712, according to selecting execution command adapted thereto.
In this embodiment, proximity transducer and ambient light sensor can be two independent modules, and the two knot
Structure layout is distant；Or can also only have ambient light sensor, and be not close to sensor.
When solving user and terminal LCD backlight being set to be automatically adjusted, user misoperation can be made after having blocked sensor
Becoming terminal demonstration abnormal, when causing user to use the technical problem that inconvenience even cannot use, step S708 can be direct
Skip, enter step S710.
Fig. 8 is the flow chart 3 of the control method of backlight illumination according to the preferred embodiment of the invention, as described in Figure 8, and should
