Claim 0:
1. A display driving integrated circuit, comprising:
a control circuit, configured to control a current driving circuit and a scanning circuit according to at least one driving parameter, wherein the current driving circuit is suitable for driving a plurality of driving lines of a light emitting diode array, and the scanning circuit is suitable for driving a plurality of scanning lines of the light emitting diode array; and
a driving parameter determination circuit, coupled to the control circuit to provide the at least one driving parameter, wherein the driving parameter determination circuit dynamically adjusts the at least one driving parameter for a target light emitting diode in the light emitting diode array according to a grayscale value of the target light emitting diode, wherein the driving parameter determination circuit comprises:
a multiplexer, having a plurality of selection terminals respectively coupled to different parameter values of the at least one driving parameter, wherein a common terminal of the multiplexer is coupled to the control circuit to provide the at least one driving parameter; and
a distinguish logic circuit, coupled to a control terminal of the multiplexer, wherein the distinguish logic circuit controls the multiplexer according to the grayscale value of the target light emitting diode, so that the multiplexer selects one of the parameter values as the at least one driving parameter of the target light emitting diode.
