The adjustable grayscale of display screen is adjusted on default gamma curve by IC so that the gamma value institute specified is transferred in the brightness of adjustable grayscale
Corresponding brightness.The operation can make grayscale transition more smooth.
Step 120, carry out full grayscale scanning to display screen.
Exemplary, the grayscale of display screen can be 32 grades of grayscale or 256 grades
Grayscale, for 256 grades of grayscale, its full grayscale is expressed as 0~255 grayscale, wherein 0 grayscale is lowermost level grayscale, table
To show completely black, 255 grayscale are highest grayscale, represent complete white, from 0 grayscale to 255 grayscale i.e. from rudimentary grayscale to advanced grayscale, ash
Rank brightness gradually increases.The operation can with the display picture of automatic identification display screen grayscale transition, further identify display screen 0~
The brightness of 255 grayscale, completes the full grayscale scanning to display screen.
Step 130, judge whether full grayscale scanning times exceed preset times.If full grayscale scanning times are not less than default

The brightness value of grayscale can be adjusted by gray scale voltage, and the gray scale voltage of only adjustable grayscale can be direct
Adjust, by adjusting the gray scale voltage of adjustable grayscale, change the voltage of the internal resistance distribution of Driver IC, to adjust other indirectly
The gray scale voltage of grayscale, so as to adjust the brightness value of other grayscale.
Exemplary, which can include：The gray scale voltage of the advanced adjustable grayscale of the closest abnormal grayscale of increase,
Or/and reduce the gray scale voltage of the rudimentary adjustable grayscale closest to abnormal grayscale.Wherein, closer to the grayscale of adjustable grayscale, its
Brightness value increases or reduces more.For example, 1~5 grayscale, 1 grayscale and 5 grayscale are adjustable grayscale, 4 grayscale are scanned as exception
Grayscale, its 3 grayscale of brightness ratio are low.At this point it is possible to increase the gray scale voltage of 5 grayscale, correspondingly, the brightness value of 4 grayscale is increased
It is more increased than 3 grayscale more, finally reach the brightness value of even more than 3 grayscale；The gray scale voltage of 1 grayscale can also be reduced, accordingly
, 4 grayscale of ratio that the brightness values of 3 grayscale reduces reduces more, finally less than the brightness value of 4 grayscale.Furthermore it is also possible to increase 5
The gray scale voltage of grayscale, while reduce the gray scale voltage of 1 grayscale, improve the efficiency of adjustment gray-scale intensity.
Step 160, end operation.
The method of adjustment for the grayscale transition that the embodiment of the present invention one provides, by carrying out full grayscale scanning to display screen, knows
Do not go out abnormal grayscale, then the adjustable grayscale near abnormal grayscale is adjusted, the brightness of abnormal grayscale is also changed correspondingly, most
