Refer to Fig. 1, the process flow diagram of the back light brightness regulating method preferred embodiment that Fig. 1 is mobile terminal provided by the invention, as shown in the figure, said method comprising the steps of:
Step S100, the first control strip that is provided in advance adjusting backlight luminance on the display screen of mobile terminal and the second control strip;
Step S200, when described the first control strip and the second control strip being detected and be touched simultaneously, according to the position calculation that is touched on described the first control strip and the second control strip, go out backlight brightness values;
Step S300, according to the corresponding backlight illumination that regulates described mobile terminal of described backlight brightness values.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
In step S100, on the display screen of mobile terminal, be provided in advance the first control strip and second control strip of adjusting backlight luminance.Specifically, described mobile terminal can be the mobile terminals such as mobile phone, panel computer.Described mobile terminal is provided with touch-screen, is used for receiving user's touch operation and slide.Existing mobile terminal is generally that display screen and touch-screen stack are arranged.
Refer to Fig. 2, in the back light brightness regulating method that Fig. 2 is mobile terminal provided by the invention, touch the schematic diagram detecting.As shown in the figure, it is the first control strip of R1 that length is set on the touch-screen of mobile terminal, the length of described the first control strip represents with R1, the upper left corner coordinate of described the first control strip is (x11, y11), the coordinate in the lower right corner of described the first control strip is (x12, y12), wherein, x12-x11=R1.Coordinate system is as shown in Figure 2 chosen, and x12 is greater than x11, and y12 is greater than y11.Like this, these two points have formed the touch area of described the first control strip.As shown in Figure 2, when touch point coordinate (x, y) on touch-screen being detected meets x11≤x≤x12 and y11≤y≤y12, this touch point (x, y) is positioned at the first tune control strip.
The second control strip is set on mobile terminal touch screen, and the length of described the second control strip represents with R2, and the upper left corner coordinate of described the second control strip is (x21, y21), the coordinate in the lower right corner of described the second control strip is (x22, y22), wherein, x22-x21=R2.In like manner, the touch area of the second control strip is that upper left corner coordinate is the rectangle that (x22, y22) forms for (x21, y21) with the coordinate in the lower right corner.As shown in Figure 2, when touch point coordinate (x, y) being detected and meet x21≤x≤x22 and y21≤y≤y22, this touch point (x, y) is positioned at the second control strip.
In described step S100, also that the backlight brightness values L of mobile terminal is associated with the length of described the first control strip.Specifically, identical with control strip control volume and the brightness size of existing mobile terminal, by the length linear dependence of the backlight brightness values L of mobile terminal and described the first control strip.When the point of the touch of user on described the first control strip more left, backlight brightness values is less, more to the right, backlight brightness values is larger, until the position of touch point is in shown in horizontal ordinate x12(Fig. 2) time, while being namely described the first control strip the rightest, the backlight brightness values of mobile terminal is adjusted to maximum, i.e. Lmax.
