Patent ID: 7940242

Claim:
A driving circuit for driving a liquid crystal display device, said driving circuit comprising: a first timing controller for receiving a first part of digital image data; a second timing controller for receiving a second part of said digital image data; and a plurality of data drivers, each data driver is directly connected to the first timing controller and the second timing controller and configured to receive said first part and said second part of said digital image data through said first timing controller and said second timing controller, respectively, for driving said liquid crystal display device; wherein each said data driver includes: a first shift register for receiving a first enable signal and a first clock signal; a second shift register for receiving a second enable signal and a second clock signal; a first line buffer for receiving a first digital image data, wherein said first shift register utilizes said first enable signal and said first clock signal to input a corresponding portion of said first part of said digital image data as said first digital image data into said first line buffer: a second line buffer for receiving a second digital image data, wherein said second shift register utilizes said second enable signal and said second clock signal to input a corresponding portion of said second part of said digital image data as said second digital image data into said second line buffer; a third line buffer for receiving and combining said first digital image data stored in said first line buffer and said second digital image data stored in said second line buffer; and a D/A converter for receiving said combined first and second digital image data stored in said third line buffer and converting said combined first and second digital image data into analog image data for subsequent use by the liquid crystal display device.
