And it's really complicated to do that because if you think about it, I'm going to show you an image and you have, you know, 2000 backlight regions and you know what color every pixel is supposed to be.

But for like the one inch by one inch region or the one centimeter by one centimeter region that's behind this particular set of pixels in this like, you know, drawing of a landscape or something.

What color should that RGB backlight be?

Because you just got one R, one G and one B for that little tiny region of the backlight.

What color should we make it?

Well, if most of the pixels are blue, you can just make the backlight blue and then you get super duper blue and it'll be really bright with lots of color volume because you've got a blue backlight going through a blue filter.

It'll be great.

But what if there's like tons of different colors in that little one centimeter region on your screen?

What color should the backlight be?

Now, do you average them?

Like anyway, that's what that's why it's computationally tricky to do that.

But what it gives these screens is more color volume.

Instead of just having a blue backlight with color filters that are imperfect, now we can crank up the color volume with these RGB backlights.

In fact, some of them don't just have RGB behind there.

They have RGB backlights and some of them add a yellow RGBY or a cyan RGBC backlight regions.

very complicated.

Uh, the, the war of words at CES was very hot because some people are like, well, if you do that, like then you, you have your RGB backlight region and you decided this backlight is going to be orange, but now you have some pixels that didn't need any orange.

And then we're getting a little bit of orange bleed through.

So your colors are all muddied because you're not able to control the colors, the individual pictures you're just putting this back.

Anyway, it's very complicated.
