Optics Express, 2019 Local dimming techniques have been widely studied to achieve a high contrast ratio and low power consumption for liquid crystal displays. The luminance of a backlight is reduced according to some characteristics of an input image and the pixel data are boosted to compensate for the dimmed backlight. In addition, because a backlight block is affected by
