This is one of those times when we get to pit two of the best TVs available against each other.
We have the Sony Bravia 9 — the most advanced mini-LED QLED TV made to date — and the Sony A95L , regarded by many as the best OLED TV made to date.
The Bravia 9 is a mini-LED TV, which means there are lots of tiny lights. The light emitted by those glorified light strips goes through a diffuser layer so the light gets spread out. It then goes through a polarizer that controls light waves, and then the light goes through a color filter. And then, finally, that now-colored light is either allowed through or mostly blocked out by the LCD — or liquid crystal — layer.
Because each pixel in an OLED TV emits light — or not — they are extremely good at contrast. Colors are brighter, and blacks are totally black. And when you start from pure black, you set the stage for infinite contrast. It’s just a question of how bright you can get on the other side of the spectrum.
So TV manufacturers had to get clever. If the LCD cell isn’t good at blocking light, then the best way to get closer to black is by not having any light behind the LCD cell in the first place. And, thus, local dimming was born. The TV shuts off the LEDs behind the LCD, and the TV gets better blacks. But there was still an opportunity to make this backlighting even more precise. That’s where mini-LEDs come in. By using much smaller LED lights, the TVs have even more precise control of the backlight, illuminating much smaller areas of the screen. And break down the massive number of mini-LEDs into an equally massive number of zones that could be dimmed, there’s now an even more precise backlight. That’s when the halo and blooming gets so minute that it’s really tough to see it at all.
But the lingering difference — the reason this OLED looks more contrasty than this mini-LED LCD TV — is hiding at the micro level. Which means to show you, we need to use a microscope and really zoom in on what’s going on. So what happens is the contrast in these tiny areas on this mini-LED TV simply cannot be as good as the contrast in those same areas on an OLED.
So if OLED is the undisputed king of contrast, then why aren’t all TVs OLED TVs? There are two primary reasons. One is that OLED TVs are more expensive to make, and thus they are expensive to buy. But the other reason is just as important: OLED TVs struggle to get as bright as LCD TVs. And while true blacks deliver a higher-impact display of contrast, there is something to be said for brightness, too.
