Abstract: A display driving integrated circuit (IC) and a driving parameter adjustment method thereof are provided. The display driving IC includes a control circuit and a driving parameter determination circuit. The control circuit controls a current driving circuit and a scanning circuit according to a driving parameter, wherein the current driving circuit is suitable for driving multiple driving lines of a light emitting diode (LED) array, and the scanning circuit is suitable for driving multiple scanning lines of the LED array. The driving parameter determination circuit is coupled to the control circuit to provide the driving parameter. The driving parameter determination circuit dynamically adjusts the driving parameter for a target LED in the LED array according to a grayscale value of the target LED.
