1. A multiple channel programmable gamma correction voltage generator, comprising: a reference voltage applied across a resistor ladder; said resistor ladder including M adjustable tap resistors distributed along said resistor ladder, each providing a corresponding one of M tap voltages distributed according to a gamma correction value, wherein M is a positive integer; M buffers, each having an input receiving a corresponding one of said m tap voltages and an output providing a corresponding one of m gamma correction voltages; select logic that selects a tap point of each of said m adjustable tap resistors to select each of said m tap voltages based on corresponding select values; and a programmable non-volatile memory device, coupled to said decoder logic, that provides said select values indicative of said gamma correction value.
