First embodiment
Referring to Fig. 1, the first embodiment of the present invention provides a kind of display brightness method of adjustment, including：
Step 101, during mobile terminal light modulation is detected, current light modulation brightness is through default automatic electric ductility limit
During ACL switching points processed, the first input GTG of the first pixel of the display interface of mobile terminal is obtained；Wherein, ACL switching points
For the switching point that ACL is opened and closed.
Wherein, the brightness is conditioned by the brightness control function that brightness is mobile terminal is dimmed, it is generally the case that existing shifting

Step 102, according to the first corresponding relation between input GTG set in advance and readjustment brightness, determines and first
The corresponding first readjustment brightness of input GTG.
Wherein, in the first corresponding relation, different input GTGs correspond to different readjustment brightness.Readjustment brightness is to open
With the light modulation brightness that currently input GTG matches after opening ACL, and when the current dimming process of mobile terminal is figure from low to high
The output GTG of picture gradually increases, and in order to offset the growth of output GTG, readjustment brightness is set below current light modulation
Brightness, to offset the GTG mutation that the change of light modulation brightness brings；When the current dimming process of mobile terminal is figure from high to low
The output GTG of picture is gradually lowered, and is set above currently dimming brightness readjustment brightness, to offset changing for light modulation brightness
Become the GTG mutation for bringing.
Step 103, according to second pair between the display brightness of readjustment set in advance brightness and the pixel of display interface
Should be related to, determine the first display brightness corresponding with the first readjustment brightness；Wherein, in the second corresponding relation, adjust back brightness and show
Show brightness into curvilinear correlation, and the corresponding display brightness of higher readjustment brightness is not less than the corresponding display of relatively low readjustment brightness
Brightness.
Wherein, display brightness is the actual displayed brightness of mobile terminal display screen curtain.In second corresponding relation, brightness is adjusted back
With display brightness into curvilinear correlation and into positive correlation.GTG and readjustment will be input into by the first corresponding relation and the second corresponding relation
Relation between brightness, readjustment brightness and display brightness, changes into the corresponding relation between input GTG and display brightness, also
Be brightness to be adjusted back as an intermediate variable, complete the transformation being input between GTG and display brightness, make display brightness and input
GTG is related, and not only related to light modulation brightness, to offset the jump in brightness in ACL switching points.
Step 104, according to the first display brightness, adjusts the display brightness of display interface.
Wherein, in order to avoid dimming process, the switching dot image opened and closed in ACL shows that GTG has saltus step,
When brightness is dimmed through ACL switching points, the first display brightness is determined by GTG is input into, and according to the first display brightness, adjustment is aobvious
Show the display brightness at interface, to offset GTG saltus step and jump in brightness in ACL switching points.
Preferably, during the light modulation brightness of mobile terminal is turned down, current light modulation brightness is through ACL switching points

<An, the display brightness with a1 curvilinear correlations are L1, and the display brightness with a1 curvilinear correlations is L2 ..., with a128 curvilinear correlations
Display brightness is L128.As now brightness is raised, in order to offset the change of brightness, readjustment brightness now is less than original tune
Brightness (b points).
According to the second corresponding relation, the correspondingly higher readjustment brightness of higher input GTG, if include 128 readjustments put and
ACL is opened after input GTG is more than 127, now the corresponding a1 of the maximum 255 of input GTG, input GTG 254 is corresponding
A2 ..., the corresponding a128 of input GTG 128.
So, during the light modulation brightness of mobile terminal is turned down, light modulation brightness is input into ash when b points, now
It is L1 that rank is the 255 corresponding display brightness of pixel, and it is L2 ... to be input into the corresponding display brightness of pixel that GTG is 254,
It is L128 (Ln) that input GTG is the 128 corresponding display brightness of pixel, is below the corresponding display brightness of b points, and higher
The corresponding display brightness of input GTG lower, turn down the impact to screen display brightness to offset brightness, it is to avoid cause vision
On mutation.

First display brightness is generated display brightness collection, then concentrates one preset data of acquisition, or average or maximum from display brightness by this
Or minima, to obtain suitable target display brightness, according to the display brightness that target display brightness adjusts display interface.
Alternatively, after step 104, the method includes：
When the light modulation brightness for detecting mobile terminal changes, the display brightness of display interface is updated.
Wherein, when light modulation brightness changes, degree of lightening and display brightness are renewed back to, bright with the display for keeping suitable
Degree.
