Adaptive Stepping-Control System and Method for Dynamic Backlight Control

摘要

An adaptive stepping-control system and method for dynamic backlight control (DBLC) is disclosed. A stepping-control unit adjusts output of a dynamic backlight control (DBLC) device, such that the backlight luminance generated from a backlight unit may change smoothly. The amount of change of the backlight luminance per unit time (or stepping rate) varies according to the content of the image data.
