One magnitude of voltage is adjusted to the second magnitude of voltage, N >=2.
In the parameter adjusting method that the embodiment of the present invention provides, as it is shown on figure 3, can pass through
Display Controller configures still image detector unit (Still Picture Detect, SPD),
In order to monitor whether Display Controller reads consecutive identical N frame from Frame Buffer
Image, i.e. in order to monitor the two field picture that Display Controller currently reads from Frame Buffer
The most identical with the most front N-1 two field picture of the current two field picture read.
Wherein, due in the output procedure of image, Display Controller originally seek to from
Frame Buffer reads the image that will export of each frame, therefore, in the embodiment of the present invention
