According to Sony it is edge lit but with a proprietary new bit of tech called Slim Backlight Drive. Sony has taken the traditional single row of LED's and doubled them. Then like Samsung they have added 'Quantum Dots' but unlke Samsung's using the Quantum Dots in the LCD panel, Sony has put their Quantum Dots in tubes that the LED's shine through. The Quantum Dot technology helps increase contrast levels and make colors pop. And along with the two rows of LED's shining through Quantum Dots, Sony is using two additional panels to direct the LED's light into 'zones' that allow for localized dimming, helping make blacks look close to OLED black and increasing the bright areas of the image to increase contrast range.
Sorry, there was a problem. Please try again later.A little more info on the Slim Backlight Drive+ ..... For last years 930D Sony put the two rows of LEDs along the left and right edge. Prior models of edge lit LED TV's, Sony's and others, offered a single row of LED's along the sides. But remember one of the features of these sets are the Slim Backlight Drive+ panels that allow for better localized dimming by creating lighting zones. One of the upgrades for the 2017 E models is the two rows of calibrated beam LEDs have been moved to the top and bottom and the Slim Backlight Drive panels have been reoriented to allow more lighting zones with better control. Just a guess (Sony's keeping the nuts and bolts technology of Slim Backlight Drive+ a secret) but it's likely that shooting the LED beams across the shorter axis (top to bottom) allows more light to reach the center of the screen and of course using many more LEDs along the length provides more lighting zones and better overall brightness. Not a big deal but because the question specifically referred to edge lighting technology and the E models are now unique in that regard it seemed worth while to point it out.
Sorry, there was a problem. Please try again later.It's a hybrid back lit television. Sony calls it slim drive back lit. So neither.
