9. display data adjustment method as claimed in claim 6, which is characterized in that in the step S4, the APL algorithm mould Multiple adjustment nodes corresponding with multiple node APL values are bright according to the APL value of original data (RGB) and respectively for block (30) Degree obtains the corresponding concrete mode for adjusting brightness:When the APL value of original data (RGB) is equal to multiple node APL values In one when, using corresponding adjustment node brightness as adjustment brightness;When the APL value of original data (RGB) is less than more When the smallest one in a node APL value, using the corresponding adjustment node brightness of the smallest APL value as adjustment brightness; When the APL value of original data (RGB) is greater than in multiple node APL values maximum one, by a maximum APL value Corresponding adjustment node brightness is as adjustment brightness;When the APL value of original data (RGB) is located at neighbouring two of any number When between a APL nodal value, corresponding adjustment brightness is calculated by way of interpolation.
10. display data adjustment method as claimed in claim 6, which is characterized in that the data grayscale regulation coefficient calculates Formula is k=Lumi/255;
Wherein, k is data grayscale regulation coefficient, and Lumi is adjustment brightness.
