The present invention provides a kind of back light brightness regulating method and system of mobile terminal, to make the purpose of the present invention, technology
Scheme and advantage are clearer, clear and definite, and the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.It should manage
Solution, the specific embodiments described herein are merely illustrative of the present invention, is not intended to limit the present invention.
Referring to Fig. 1, Fig. 1 is the flow of the back light brightness regulating method preferred embodiment of mobile terminal provided by the invention
Figure, as illustrated, the described method comprises the following steps：
Step S100, the first control strip and of adjusting backlight luminance is provided on the display screen of mobile terminal in advance
Two control strips；
Step S200, when detecting first control strip and the second control strip while being touched, according to described first
Backlight brightness values are gone out by touch location calculation on control strip and the second control strip；
Step S300, the backlight illumination of the mobile terminal is correspondingly adjusted according to the backlight brightness values.
Above-mentioned steps are described in detail with reference to specific embodiment.
In the step s 100, the first control strip of adjusting backlight luminance is provided on the display screen of mobile terminal in advance
With the second control strip.Specifically, the mobile terminal can be the mobile terminals such as mobile phone, tablet personal computer.The mobile terminal is set
Touch-screen is equipped with, for receiving the touch operation of user and slide.Existing mobile terminal be usually by display screen and
Touch-screen superposition is set.
Referring to Fig. 2, signals of the Fig. 2 for touch detection in the back light brightness regulating method of mobile terminal provided by the invention
Figure.As illustrated, the first control strip that length is R1, the length of first control strip are set on the touch-screen of mobile terminal
Represented with R1, the top left co-ordinate of first control strip is（X11, y11）, the coordinate in the lower right corner of first control strip is
（X12, y12）, wherein, x12- x11=R1.Coordinate system as shown in Figure 2 is chosen, and x12 is more than x11, and y12 is more than y11.So,
The two put the touch area for constituting first control strip.As shown in Fig. 2 work as the touch point coordinates detected on touch-screen
（X, y）When meeting x11≤x≤x12 and y11≤y≤y12, then the touch point（X, y）Adjusted positioned at first in control strip.
Second control strip is set on mobile terminal touch screen, the length of second control strip is represented with R2, described
The top left co-ordinate of two control strips is（X21, y21）, the coordinate in the lower right corner of second control strip is（X22, y22）, wherein,

Value x2min and abscissa maximum x2max.
Then, is determined with the minimum value of abscissa in touch point on the second control strip and the arithmetic mean of instantaneous value of maximum
The second regulated value in two control strips is：(x2min+x2max)/2-x21.Second regulated value, refers to the second control strip
The distance of point on the control strip of central point distance second that upper user's finger touches where abscissa minimum value.
The difference of maximum and minimum value further according to abscissa in touch point on the first control strip and the second control strip
The ratio of length, second regulated value is converted to the first regulated value on the first control strip, and first regulated value is：
[(x2min+x2max)/2-x21]*(x1max-x1min)/R2.That is, the second regulated value in the second control strip is turned
Change in the first control strip：By the length of the second control strip and the ratio of x1min to x1max in the first control strip, i.e., by the
Length (x1max-x1min) amplification R2/ (x1max-x1min) times of user touch area, obtains the second control in one control strip
The length R2 of bar.Therefore, second regulated value is converted to the first regulated value on the first control strip, first regulated value
For：[(x2min+x2max)/2-x21]*(x1max-x1min)/R2.
Determine that the final regulated value M on first control strip is further according to first regulated value：x1min-x11+
[(x2min+x2max)/2-x21]*(x1max-x1min)/R2.The first regulated value that will be obtained is plus x1min-x11
Final regulated value on first control strip, it is specially：x1min-x11+[(x2min+x2max)/2-x21]*(x1max-
x1min)/R2。
Finally, show that the backlight brightness values L of the mobile terminal is according to the final regulated value：L=M*Lmax/R1, its
In, L is the backlight brightness values of mobile terminal, and M is the final regulated value on first control strip；Lmax be mobile terminal most
Big backlight brightness values.
