Claim 11:
12. A method used in a detection circuit for controlling a display controller, the display controller being configured to generate a plurality of backlight data according to a plurality of image data, the method comprising:
receiving the plurality of image data and converting the plurality of image data into a plurality of region data;
receiving at least one first region data among the plurality of region data;
receiving at least one first backlight data corresponding to the at least one first region data among the plurality of backlight data from a backlight data processing circuit of the display controller;
comparing the at least one first region data with the at least one first backlight data to generate a comparison result, wherein one of the at least one first region data corresponding to a first region of a display panel is compared with one of the at least one first backlight data in the first region; and
outputting a control signal to control an output setting of the display controller according to the comparison result.
