00:00:00.000 --> 00:00:03.760
Many versions of things have historically proven to be pretty popular.

00:00:03.760 --> 00:00:07.680
The iPod mini, mini muffins, mini me.

00:00:07.680 --> 00:00:10.700
But a new one called mini LED could have a big time effect

00:00:10.700 --> 00:00:15.200
on the way we watch TV or use our computers. But before we go any further,

00:00:15.200 --> 00:00:20.640
you guys gotta know that mini LED is not the same thing as micro LED.

00:00:20.640 --> 00:00:23.800
They are completely separate. Micro is also cool,

00:00:23.800 --> 00:00:28.280
and you can learn more about it right up here. But mini is the one that you might actually be able

00:00:28.320 --> 00:00:31.780
to get your hands on for an affordable price in the near future.

00:00:31.780 --> 00:00:35.680
As for why it matters, well it first helps to understand how it relates

00:00:35.680 --> 00:00:39.880
to other kinds of TV technology. If you've ever been to a big box store

00:00:39.880 --> 00:00:44.820
and seen how striking OLED TVs are next to non OLED models,

00:00:44.820 --> 00:00:50.080
the difference is due to the fact that OLEDs have a very high contrast ratio

00:00:50.080 --> 00:00:53.400
because individual pixels can be turned completely off,

00:00:53.400 --> 00:00:57.680
producing deep blacks without light bleed from nearby bright objects.

00:00:57.680 --> 00:01:02.880
Non OLED TVs, on the other hand, rely on backlighting that is always turned on.

00:01:02.880 --> 00:01:06.680
To create images then, an LCD layer in front of the backlight

00:01:06.680 --> 00:01:10.120
selectively blocks the light in different areas of the screen.

00:01:10.120 --> 00:01:15.600
But it can't block the light completely, meaning that blacks can end up looking closer to gray.

00:01:15.600 --> 00:01:19.120
To improve this, LCDs use a trick to improve their contrast

00:01:19.120 --> 00:01:23.680
called local dimming. The idea is that the backlight can selectively dim

00:01:23.680 --> 00:01:26.680
or even switch off in certain areas of a screen

00:01:26.680 --> 00:01:31.840
where the image is dark or black. And local dimming can definitely help,

00:01:31.840 --> 00:01:36.280
but it is far from a perfect solution. You see TVs that have this feature

00:01:36.280 --> 00:01:39.320
typically have their backlight split into zones

00:01:39.320 --> 00:01:44.040
that dim or turn off as a group. But for the effect to work well,

00:01:44.040 --> 00:01:49.840
you need lots and lots of zones, which means lots of LEDs adding cost, heat,

00:01:49.840 --> 00:01:52.920
and power consumption. That's where many LEDs come in.

00:01:52.920 --> 00:01:57.760
Thanks to some recent technological advances, LEDs have not only become more efficient,

00:01:57.760 --> 00:02:03.080
but also smaller, which is exactly the idea behind a mini LED display.

00:02:03.080 --> 00:02:07.280
Mini LEDs are often less than a 10th of a millimeter across,

00:02:07.280 --> 00:02:11.600
meaning that you can fit many more of them in the backlight layer of a TV,

00:02:11.600 --> 00:02:15.720
allowing much smaller zones of lighting control. To put this in context,

00:02:15.720 --> 00:02:18.880
a traditional local dimming TV from the last couple of years

00:02:18.880 --> 00:02:23.240
might have dozens or maybe a few hundreds of zones.

00:02:23.240 --> 00:02:31.160
While these recently released mini LED displays from ASUS and TCL have about 1,000 individual zones.

00:02:31.160 --> 00:02:35.480
This should help them do a much better job of preventing that blooming effect

00:02:35.480 --> 00:02:40.200
that you sometimes see with local dimming where bright objects in a dark scene

00:02:40.200 --> 00:02:46.240
have this aura or halo glowing around them because the zone that's lighting the bright object

00:02:46.240 --> 00:02:50.560
is simply too large to be confined to the area where it's supposed to be.

00:02:50.560 --> 00:02:53.720
Of course, mini LED is a newer technology right now

00:02:53.720 --> 00:02:59.280
so you can expect to pay more for it, but it's well positioned to be more affordable than OLED,

00:02:59.280 --> 00:03:02.800
especially after the early adopter tax wears off.

00:03:02.800 --> 00:03:07.360
And with micro LED being quite a ways off from hitting the mass consumer market

00:03:07.360 --> 00:03:12.160
due to high costs and manufacturing complexity, mini LED looks to be an appealing option

00:03:12.160 --> 00:03:15.540
to tide us over until then. Now if you'll excuse me,

00:03:15.540 --> 00:03:20.040
I've got to go to Tim Hortons because I've got a sudden hankering for some mini donuts.

00:03:20.040 --> 00:03:23.640
So thanks for watching guys. Like, dislike, check out our other videos

00:03:23.640 --> 00:03:27.840
and leave a comment if you have suggestion for a future fast as possible.

00:03:27.840 --> 00:03:31.760
I might even do the whole thing instead of leaving out a word like I did a second ago.

00:03:31.760 --> 00:03:34.960
