Classification: CPC G | IPC G

Claim 0:
1. A detection circuit for a display controller, the display controller being configured to generate a plurality of backlight data according to a plurality of image data, the detection circuit comprising:
a resize circuit, configured to receive the plurality of image data and convert the plurality of image data into a plurality of region data; and
a comparison circuit, coupled to the resize circuit, configured to:
receive at least one first region data among the plurality of region data from the resize circuit;
receive 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;
compare 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
output a control signal to control an output setting of the display controller according to the comparison result.
