Gamma correction circuit, display drivers, electro-optical devices, and electronic equipment

A display driver for driving a plurality of data lines of an electro-optical device, the display driver comprising:

• gamma correction circuits for first to p-th color components provided for first to p-th (p is an integer equal to or more than two) color components, respectively, the first to p-th color components constituting one pixel, a gamma correction circuit for an i-th (1≦i≦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 selects a reference voltage corresponding to the converted gray-scale data of each color component among reference voltages of 2j types and outputs the reference voltage as a data voltage for each color component;
• and
• a driving circuit which drives the data lines based on a data voltage of each color component for each color component;
• wherein the gamma correction circuit for an i-th color component generates the converted gray-scale data of j bits so that the voltage selection circuit selects and outputs, as the data voltage, one of the reference voltages of 2j types to which a gray-scale value corresponding to ki bit gray-scale data is allocated.
