The output grayscale of picture gradually increases, and in order to offset the growth of output grayscale, readjustment brightness is set below current light modulation
Brightness, to offset the change bring grayscale mutation of light modulation brightness；When the current dimming process of mobile terminal is figure from high to low
The output grayscale of picture gradually decreases, and readjustment brightness is set above current light modulation brightness, to offset changing for light modulation brightness
Become the mutation of bring grayscale.
Step 103, according to second pair between preset readjustment brightness and the display brightness of the pixel of display interface
It should be related to, determine the first display brightness corresponding with the first readjustment brightness；Wherein, it in the second corresponding relationship, adjusts back brightness and shows
Show brightness into curvilinear correlation, and the corresponding display brightness of higher readjustment brightness is not less than the corresponding display of lower readjustment brightness
Brightness.
Wherein, display brightness, that is, mobile terminal display screen curtain actual displayed brightness.In second corresponding relationship, brightness is adjusted back
It at curvilinear correlation and is positively correlated with display brightness.Grayscale and readjustment will be inputted by the first corresponding relationship and the second corresponding relationship
Relationship between brightness, readjustment brightness and display brightness, the corresponding relationship being converted between input grayscale and display brightness, also
It is readjustment brightness as an intermediate variable, completes the transformation between input grayscale and display brightness, make display brightness and input
Grayscale is related, and not only related to light modulation brightness, to offset the jump in brightness in ACL switching point.
Step 104, according to the first display brightness, the display brightness of display interface is adjusted.
Wherein, in order to avoid showing that grayscale has jump in the switching point image that ACL is opened and closed in dimming process,
When dimming brightness by ACL switching point, the first display brightness is determined by input grayscale, and according to the first display brightness, adjustment is aobvious
Show the display brightness at interface, to offset in the grayscale jump of ACL switching point and jump in brightness.

< an, the display brightness with a1 curvilinear correlation are L1, and the display brightness with a1 curvilinear correlation is L2 ..., with a128 curvilinear correlation
Display brightness is L128.Since brightness is raised at this time, in order to offset the change of brightness, readjustment brightness at this time is lower than original tune
Brightness (b point).
According to the second corresponding relationship, higher input grayscale corresponds to higher readjustment brightness, if include 128 readjustment points and
Be more than to open ACL after 127 in input grayscale, input the corresponding a1 of maximum value 255 of grayscale at this time, input grayscale 254 corresponds to
A2 ..., the corresponding a128 of input grayscale 128.
So, during the light modulation brightness of mobile terminal is turned down, when b point is passed through in light modulation brightness, input is grey at this time
The corresponding display brightness of the pixel that rank is 255 is L1, and the corresponding display brightness of pixel that input grayscale is 254 is L2 ...,
Inputting the corresponding display brightness of pixel that grayscale is 128 is L128 (Ln), is below the corresponding display brightness of b point, and higher
The corresponding display brightness of input grayscale it is lower, turn down influence to screen display brightness to offset brightness, avoid vision
On mutation.
