Patent ID: 7965286

Claim:
A timing controller, comprising: a line pattern detector configured to divide received data into a plurality of unit blocks and to detect a line polarity of each of a plurality of horizontal lines included in each of the unit blocks; and a frame pattern detector to generate a polarity control signal to control a data inversion method based on a frame image pattern detected based on line polarities of the respective horizontal lines, the frame pattern detector comprising: a frame image detection block to determine the frame image pattern based on a result of line polarity detection; and an inversion method controller to generate the polarity control signal to control the data inversion method based on the frame image pattern, wherein the frame image detection block comprises: a block image detector to detect an image pattern of each of the unit blocks based on the result of the line polarity detection; a second adder configured to count image patterns coinciding with a first data inversion method among image patterns of the respective unit blocks so as to obtain a third sum and to count image patterns coinciding with a second data inversion method among the image patterns of the respective unit blocks so as to obtain a fourth sum; and a frame image detector to compare the third sum with the fourth sum and to determine the frame image pattern.
