A data driver includes gamma correction circuits for first to p-th color components for first to p-th (p is an integer equal to or more than two) color components constituting one pixel, a gamma correction circuit for an i-th (1.ltoreq.i.ltoreq.p, i is an integer) color component converting ki-bit (k1 to kp are integers) gray-scale data to converted gray-scale data of j (j>ki, j is an integer equal to or more than two) bits; a voltage selection circuit which outputs a data voltage corresponding to the converted gray-scale data of each color component among reference voltages of 2.sup.j types; and a driving circuit which drives the data lines based on a data voltage of each color component. The gamma correction circuit for an i-th color component generates the converted gray-scale data of j bits so that one of the reference voltages of 2.sup.j types to which ki bit gray-scale data becomes allocated is the data voltage.       Recently Added Patents Dinitropyrazole derivatives, their preparation, and energetic compositions comprising them Optical information recording/reproducing device, optical information reproducing device, and optical information recording medium Method and apparatus for affecting the autonomic nervous system Cleaning robot and control method thereof Buckle for center occupant for bench seat with extended travel Semiconductor device and manufacturing method thereof Encoding adjustments for animation content   Randomly Featured Patents Apparatus for generating software logic rules by flowchart design Brush handles Method to identify analyte-binding ligands Pipelined instruction processor capable of reading dependent operands in parallel Momentary contact switch having pivoting actuator mounted on switch base Sleep system Sand muller bowl liner Systems, methods, and apparatus for measuring capacitance in a stator component Peroxyacid bleach composition Method for forming a contact intermediate two adjacent electrical components © 2006-2008 PatentGenius.
