Abstract: The LED display system includes an array of LEDs and a driver circuit. The driver circuit has a PWM engine, an adder, an accumulator, a multiplier, and a frame butter. The multiplier multiplies an image data of a first bit depth (PWM) with a multiple (M) to produce an input data (PWM_M) having a second bit depth.

The input data has an integer section (PWM_MI) and a fraction section (PWM_MF). The adder adds a value of PWM_MF of a current input data with a value of a remainder in an accumulator. The PWM engine receives PWM data from the frame buffer and generates PWM pulses to drive the LED array.
