Claim 2:
3. The display driving integrated circuit according to claim 1, wherein the at least one driving parameter comprises a pulse amplitude modulation multiplier parameter and a pulse width modulation multiplier parameter,
when the grayscale value of the target light emitting diode falls within a low grayscale interval, the driving parameter determination circuit dynamically decreases the pulse amplitude modulation multiplier parameter of the target light emitting diode and dynamically increases the pulse width modulation multiplier parameter of the target light emitting diode; and
when the grayscale value of the target light emitting diode falls within a high grayscale interval, the driving parameter determination circuit dynamically increases the pulse amplitude modulation multiplier parameter of the target light emitting diode and dynamically decreases the pulse width modulation multiplier parameter of the target light emitting diode.
