Patent ID: 7564450

Claim:
An apparatus for driving a liquid crystal display device comprising: a timing controller; a data buffer for storing first and second data control signals from the timing controller, the data buffer having a first buffer and a second buffer, each of the first and second buffers capable of storing an equal number of data control signals, wherein the first buffer stores the first data control signals and the second buffer stores second data control signals; a liquid crystal display panel having a first display area and a second display area, each display area having data lines; and a data driver having a first data driver portion for supplying the first data signals to the data lines in the first display area in a first horizontal direction and a second data driver portion for supplying the second data signals to the data lines in the second display area in a second horizontal direction opposite to the first horizontal direction, wherein the first buffer includes a first data storage register for storing the first data control signals and a first data read register for reading the first data control signals from the first data storage register and supplying the first data control signals to the first data driver portion, wherein the second buffer includes a second data storage register for storing the second data control signals and a second data read register for reading the second data control signals from the second data storage register and supplying the second data control signals to the second data driver portion, wherein the first data read register stores the first data control signals from the first data storage register in a first sequence and then supplies the stored first data control signals, in a sequence inverse to the first sequence, to the first data driver portion in the first horizontal direction.
