Abstract
A control module for reducing power dissipation is connected to a column driving unit and a row driving unit. The control module includes a memory for storing display data temporarily and an arithmetic/logic unit connected to the memory. The arithmetic/logic unit takes grayscale image data of a current conducted row as a base row to compare with the grayscale image data of n rows that are temporarily stored in the memory and waiting to be scanned, so as to select the row with a minimum gray level difference as a next conducted row.
