Each of the white LEDs along the edge of the screen is controlled to suit image brightness. LEDs near dark image areas are dimmed, and only those by bright areas are lit, which saves energy and enhances contrast.

Backlighting and local dimming in the HX850 series works through independently controlled LEDs along the edges of the screen. Brightness by dark image areas is suppressed, which reduces energy consumption by up to 20%* while producing deep blacks for a vibrant, high-contrast picture. The HX750 series incorporates Dynamic Edge LED backlighting and another dimming technology that optimizes backlight brightness of the screen as a whole in response to the current image, which helps avoid consuming more power than needed.

*Compared to sets with local dimming turned "OFF". Note that local dimming is actually not a feature that can be turned "ON" and "OFF".

What defines the best picture quality usually depends on what you're watching, whether it's sports, musical performances, or other programming. The ideal level of backlighting also varies. That's why the HX750/850 series sets automatically switch to the optimal level of LED backlighting to suit the type of program, through Scene-Optimized Energy Saving technology. The televisions automatically recognize the type of program and adjust the backlight accordingly. This careful control of backlighting based on programming can reduce power consumption by about 30%*.

*Compared to when this backlight control is manually deactivated.

Other features that save energy include an ambient light sensor that adjusts screen brightness to suit the room brightness. The sets also enter standby mode automatically after a certain period of inactivity. In these ways, the HX750/850 series offers an enjoyable viewing experience with minimal power consumption.
