Display driving device for reducing power consumption and operating method thereof

Abstract

A display driving device is disclosed. The display driving device comprises: a reception circuit for receiving first display data including data values of a first group; a transmission control circuit that outputs the first display data or outputs second display data including data values of a second group, according to a result of comparing the data values of the first group with target data values; and a data processing circuit for processing the first display data or the second display data output from the transmission control circuit, wherein the transmission control circuit comprises an inverting circuit that: if the data values of the first group are not the same as the target data values, respectively, bypasses the first display data to the data processing circuit; if the data values of the first group are the same as the target data values, respectively, converts the data values of the first group respectively into the data values of the second group, which have values complementary to the data values of the first group, respectively; and outputs the second display data including the data values of the second group to the data processing circuit.
