Crosstalk between the left-eye and right-eye images is one of the main artifacts affecting the visual quality of stereoscopic liquid crystal display (LCD) systems. In this paper, a novel technique, called Optimal Backlight Modulation (OBM), is proposed to reduce crosstalk by taking the advantage of newly emerged light-emitting diode (LED) backlight panel. Unlike most existing techniques which solely aim at eliminating the effect of crosstalk, ignoring image brightness and contrast, OBM strikes a better balance by maximizing the output luminance while confining the crosstalk within a given level. A simple closed-form approximation of the optimization problem can be easily employed and solved in real time on LCD control hardware. Simulation results show that the proposed OBM algorithm provides the same or higher luminance while reducing the crosstalk by 60% compared with the other tested methods.
