SONY BACKLIGHT MASTER DRIVE
The award winning technological breakthrough for 4K HDR TVs.
LCD TVs have come a long way with Ultra High-Definition 4K TVs a standard feature and High Dynamic Range (HDR) being the next big thing. However, while panel technologies have grown leaps and bounds, there has been little improvement to backlighting.
All modern LCD TVs make use of an array of LED backlights to illuminate all those pixels that make up the image you see on your TV. Some are edge lit, where LEDs are placed along the sides of the screen. Some feature a full array of LEDs at the back of the panel. But whichever the design, all LCD TVs have an inherent problem of the LED backlights leaking across the screen causing patches of uneven brightness and dark tones that are always more grey than black.
Sony’s Backlight Master Drive™ is the first real step to revolutionise LED backlight technology and has even won the coveted Editor’s Choice Innovation Award at the 2017 HWM+ HardwareZone.com Tech Awards.
In simpler terms, Backlight Master Drive is a full-array local dimming system taken to another level. It employs a denser LED structure compared to other backlight systems, and is able to discretely control each LED, as opposed to the usual way of controlling LEDs in a group or zonal arrangement. Backlight Master Drive LEDs also have a unique optical structure that focuses each LED to prevent leaking.
The result is one of the most advanced 4K HDR TVs ever made. The Sony BRAVIA™ Z9D with Backlight Master Drive is by far the best TV you can get for 4K HDR viewing, capable of incredible brightness with crystal clear distinction between vivid lights and the darkest blacks. No other LCD TV technology comes close.
