A deep learning model was built to optimize the phase flicker performance for given pulse width modulation (PWM) driving patterns of a liquid crystal on silicon (LCOS) device. 10-bit phase modulation was physically realized with a phase flicker of 0.055% over 1024 addressed phase levels in respect to the total modulation range of <svg xmlns="http://www.w3.org/2000/svg" id="M1" style="vertical-align:-0.1876698pt" height="8.92284pt" version="1.1" viewBox="-0.0498162 -8.73517 14.312 8.92284" width="14.312pt">
