Abstract
A local dimming system adaptable to a backlight of a display includes a light shape imitation (LSI) unit that receives a pulse-width modulation (PWM) value and provides a profile data for each block of the backlight; a profile analysis unit that generates an analytic mean value according to the profile data; and a diffusion compensation unit that compares the analytic mean value with a target mean value and compensates the PWM value for light diffusion according to a result of the comparison, thereby generating a compensated PWM value.
