Person of good sense's eye is not very sensitive to brightness change now, only need to pass through pulse width modulation according to hardware adjustment mode before
The dutycycle adjustment screen intensity of signal.
According to the method for adjustment of the mobile terminal screen of the present invention, by the ambient brightness residing for current mobile terminal with showing
Show that the corresponding relation of light-source brightness obtains its corresponding display light source brightness, judge the display light source brightness and display light source brightness
The relation of threshold value：When less than the threshold value, illustrate that now change of the human eye to screen intensity can be very sensitive, therefore, by hiding
Cap layer adjusts screen intensity, i.e., by way of software adjust screen intensity；When being not less than the threshold value, pass through hardware
The mode of adjustment, i.e., adjust screen intensity by the dutycycle of pulse width modulating signal.
Pass through this programme, it is contemplated that the problem of resolving power that human eye changes under different lightness environment to brightness is different,
Under low-light level environment, the grade of brightness adjustment is refined by way of being superimposed mask layer, to solve to go out in adjustment screen process
Existing jump in brightness problem so that whole screen adjustment process is finer and smoother naturally, improving Consumer's Experience.Also, it is superimposed shade
The mode of layer is realized by way of software, does not increase hardware cost, reduces power consumption.
