Optimal local dimming for LC image formation with controllable backlighting
IEEE Transactions on Image Processing, 2013 Light emitting diode (LED)-backlit liquid crystal displays (LCDs) hold the promise of improving image quality while reducing the energy consumption with signal-dependent local dimming. However, most existing local dimming algorithms are mostly motivated by simple implementation, and they often lack concern for visual quality.

Adaptive local backlight dimming algorithm based on local histogram and image characteristics
SPIE Proceedings, 2013 Liquid Crystal Display (LCDs) with Light Emitting Diode (LED) backlight is a very popular display technology, used for instance in television sets, monitors and mobile phones. This paper presents a new backlight dimming algorithm that exploits the characteristics of the target image, such as the local histograms and the average pixel intensity of ...

Investigating subjective attributes of quality for videos displayed with local backlight dimming
2014 Sixth International Workshop on Quality of Multimedia Experience (QoMEX), 2014 This paper investigates what composes the quality of videos displayed on LCD with local backlight dimming. In a subjective experiment, participants assessed the level of nine attributes defined using the Qualitative Descriptive Analysis method. Results show that three attributes (Contrast, Change over time and Grain) vary significantly depending on the

Deep CNN-based local dimming technology
Applied Intelligence, 2021Local dimming is a feature on light-emitting diode (LED) TVs that dims the backlight behind parts of the screen that are displaying black and brights the backlight behind parts of the screen that are displaying white. To improve contrast ratios (CRs) and reduce power consumption for liquid crystal displays (LCDs), local dimming technology has been ...

Local Dimming Design for LCD Backlight
2019The local-dimming backlight has recently been presented for use in LCD TVs. However, the image resolution is low, particularly at weak edges. In this work, a local-dimming backlight is developed to improve the image contrast and reduce power dissipation. The algorithm enhances low-level edge information to improve the perceived image resolution.

Pixel compesation for locally dimmed backlight displays
2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU), 2011This paper proposes a novel pixel compensation technique for Led backlight displays. The proposed technique explicitly computes the screen intensity distribution using the point spread function (PSF) of the individual Leds to calculate per-pixel-based intensity decrease due to the dimmed Leds.
