Abstract:
A device driver which includes an input driver configured to produce a sequence of uncompensated drive signals along with compensation circuitry connected to receive the uncompensated drive signals and to produce corresponding compensated drive signals. The compensation circuitry is capable of storing two or less control points that define a single compensation curve such as a Bezier curve, with the compensation circuitry converting the uncompensated drive signals to the corresponding compensated drive signals utilizing the control points. An output driver is configured to drive a device such as one or more light emitting diodes to be connected to the output driver with the compensated drive signals.
