Abstract
A local dimming system includes a light shape imitation (LSI) unit that receives a pulse-width modulation (PWM) value generated according to content of an image, the LSI unit generating luminance gain according to the PWM value; and a pixel compensation unit that performs pixel compensation on the image according to the luminance gain, thereby resulting in a compensated image. The LSI unit performs LSI computation by multiplying profile data with corresponding PWM values, and adding products of multiplication, thus resulting in a light shape.
