The award win­ning tech­no­log­i­cal break­through for 4K HDR TVs.

HWM (Singapore) - - Sony Special -

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+ Hard­ 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.
