Patent ID: 8730274

Claim:
A liquid crystal display (LCD) system comprising: a liquid crystal (LC) panel; an LC panel controller configured to send output code values to the LC panel; a backlight configured to illuminate the LC panel; a backlight controller configured to control the backlight; and a display controller configured to control the backlight controller and the LC panel controller and receive input code values from an image source, wherein the LCD system uses a dynamic knee point determination of soft clipping to provide output code values to the LC panel by: obtaining a hard clip reference point using a backlight dimming ratio; and selecting the dynamic knee point and a soft clip portion using the hard clip reference point by: obtaining a first knee distance corresponding to a distance of input code values between the dynamic knee point and the hard clip reference point; and obtaining a second knee distance corresponding to a distance of input code values between the hard clip reference point and a hard clip point where the soft clip portion ends.
