Sony Backlight Master Drive Technology

According Sony it combines the deep blacks of OLED panels with 4000 nits of peak brightness. The technology incorporates more than 1000 Local Dimming zones of high-desity LED backlighting and other techniques to deliver high dynamic range (HDR). In real world environments, consumers won't see a difference between OLED's black levels and Master Drive's black levels.

Sony Backlight Master Drive Technology Prototype


Sony Slim Backlight Drive Technology
which is also mentioned in the previous clip, uses a unique grid array local dimming backlight structure to distribute the backlight source more precisely to each specific zone of the screen while maintaining a slim display.. Only the X930D Edge Lit uses this technology.


Sony (75 inch X940D) FALD is also slimmer than in previous years photo's

Cool to see Sony with another prototype of a product they almost certainly have no intention of ever producing. Very exciting.

Nothing new here. 2010 the Toshiba XZ1 has in 55"! 512 dimming zones and peak brightness of 1000cd/m². So it seems 1000 zones for I guess, a 75" panel with near 3 times the area of 55", is not really spectacular and even the Toshiba was not OLED quality. FALD LCD will still remain the same issues about discoloration because of limited sweet spot, even at front viewing. How bigger the screen and closer the viewing distance, than bigger the issue and for viewing angle the often used VA panels in Sony LCDs are even worse than this IPS panel.

Uh huh. On one hand, they are flaunting 1000 zones of hot (physically) and thick electronic gizmo designed to appeal nerds and nerds only. On the other hand, their actual shipping products are prioritizing thinness yet again. Fitting their prototype's name is "Backlight Master Drive" while their consumer products are called "Slim Master Drive"

Like i said somewere else, someone who has seen the LCd said that the TV's light output was hurting his eyes yet the blacks remain black. Don't think that we have seen that before..FALD thickness is also something manufacturers have been struggling with for years, Slim Backlight Drive seems to have solved that issue.

As impressive as the numbers are, and they really are, I'm not sure what extra of value is brought to the table by making taking a very bright number and increasing it even more to where viewers would actually mention that the output was hurting their eyes. Making FALD slim, that seems to be the real news here.

According HDGURU, the main function of the prototype was to demonstrate the Backlight Master Drive technology which will be included in some models this year.

Let me get this straight then...

Sony, which keeps making one, single model of full array TV every year in a giant size at an astronomical price, intends to make a 1000-zone backlight unit for "several models" this year?

Color me skeptical.

Saw Sony's demo yesterday at CES, was a mixed bag - the scenes (don't know the movie) inside the helicopter very nice, but when it cut away to the outside (and the comparison picture of what I'm sure was a dumbed down display to make the tech look better), was an overly bright and blown out (IMO) image.

All this HDR stuff, and again, my opinion, great for photo, mixed bag for video. Welcome to blown whites and crushed blacks, at least with all the demos I saw.

.. well. that is what HDGURU says..send them a mail.. Tom's Guide has a different story..They stated that sony has no immediate plans to incorporate the technology into its TVs, or take a stab at how much doing so might cost (Company representatives explained that it's investigating the technology as one possible way to offer consumers something on the level of OLED screens, and push the boundaries of what LCD screens can accomplish).

..so..being honest, folks at sony do not think that even their best LCd's are on the level of OLED screens

They made some of the first OLEDs, so they should know that.

I'm going to just go with Tom's here and skip my e-mail to Gary saying, "WTF Gary, why did you post such nonsense?"

Maybe I'm wrong, but I doubt it.

I still remember the DAY that I set up the demo of the XEL-1 at Best Buy. We ran a continuous loop of Disney's Dinosaur Blu-ray on it (even though the display was only 960x540 or something). I remember thinking that I would wait until it was discontinued and then try to buy it using my discount, but then when it was finally discontinued, the price didn't drop and we had to send them all back to Sony.

This guy is still using one as a PC display 9 years later:

Sony's main TV rep handled the question pretty well:


Sports Car == A1E (OLED)
Luxury Car == Z9D

Your statement I quoted begs the same question in ways is all. Sony's PR response pretty much states that OLED and LCD both have their pros and cons.

So, with that analogy, is it safe to say that the A1E will outperform the Z9D? Because in my experience is sports cars are built for performance, whereas luxury cars are built to include all the bells and whistles, usually with pretty good performance (but still behind a true sports car).

Seriously, the Z9D is not an OLED killer and the OLEDs are not a Z9D killer. Two different sets for different people with varying preferences. Both have their place and market; both have their inherent technological drawbacks.

That statement i made is the logical consequence of a Sony statement which was ''Sony wants to offer consumers something on the level of OLED screens'' In other words all Sony LCd TVs prior to the ZD9 are not on the level of OLED screens according Sony.

Folks high -up in the Sony hierachy, CEO/president Sony Electronics claim that the ZD9 is better at doing HDR than the A1E OLED, that is why the ZD9 is the 2017 flagship ...
