Q & A

什么是CRT电视，它是如何工作的？

CRT电视，也被称为管式电视，是电视技术的起点。它使用阴极射线管(CRT)来发射电子，这些电子打在涂有荧光粉的屏幕上产生图像。CRT电视从1934年开始生产，经历了从黑白到彩色，从小到大尺寸的演变，直到2000年左右逐渐被淘汰。

后投影电视有什么特点？

后投影电视以其巨大的尺寸而闻名，它们使用三个颜色的光源（光炮）从屏幕背后投射图像。虽然提供了非常大的画面，但需要不断调整光源的对齐和汇聚，否则会出现模糊的彩虹色图像，且亮度和对比度表现不佳。

等离子(Plasma)电视的工作原理是什么？

等离子电视使用屏幕上的微小气体像素袋，当电流通过时，气体变成等离子体并点亮荧光体。等离子电视是当时非常先进的技术，提供了非常薄的机身和16:9的屏幕比例。

什么是LCD电视，它与等离子电视有何不同？

LCD电视是使用液晶显示技术的电视，它们最初在背后使用紧凑型荧光灯作为背光。与等离子电视相比，LCD电视更轻，更容易移动，并且可以轻松地挂在墙上。但最初LCD电视在产生黑色方面表现不佳。

LED电视与LCD电视有何区别？

LED电视实际上是使用LED作为背光的LCD电视。LED背光相比传统的荧光灯背光可以使电视更薄，亮度更高。尽管市场上将它们称为LED电视，但实际上它们仍然是LCD技术的一种。

OLED电视与LED电视在技术上有何不同？

OLED电视使用的是有机发光二极管技术，每个像素都能自发光，不需要背光。这使得OLED电视比LED电视更轻、更薄，并且能够提供更准确的颜色和更好的对比度。

QLED电视是如何改进LED电视的？

QLED电视使用量子点技术，这是一种高效的发光纳米颗粒，可以提高LED背光的性能，使电视更亮，颜色更丰富。QLED电视在亮度和色彩表现上有所提升，但仍然存在背光泄漏的问题。

Mini LED电视与普通LED电视有何区别？

Mini LED电视使用更小、更密集的LED作为背光，这样可以更好地控制黑色水平，减少光晕和背光泄漏，提供更好的对比度和HDR性能。它们是目前基于LCD技术的最高端电视。

什么是Micro LED电视，它与OLED有何不同？

Micro LED电视是一种自发光显示技术，使用微小的LED作为像素，提供极高的亮度和对比度。与OLED相比，Micro LED可以更亮，但目前成本较高，且在常规屏幕尺寸上实现4K分辨率较为困难。

量子点显示技术未来的发展方向是什么？

量子点显示技术未来可能会发展成为独立的自发光显示技术。如果实现，它可能会提供与现有技术不同的优势，但目前仍处于早期阶段，需要时间来观察其性能和成本效益。

如何选择合适的电视类型？

选择合适的电视类型取决于个人需求和预算。考虑因素包括画质、对比度、色彩准确性、运动处理能力、价格以及房间的照明条件。每种电视类型都有其优势和局限性，了解这些可以帮助做出更明智的购买决策。

LED qled OLED mini LED micro LED so many

LEDs hey if you're confused about all

the different TV types out there I get

it I've been at this for over 23 years

and all those acronyms still make my

head spin not to worry though I'm about

to explain every TV type in terms that

are super easy to understand

[Music]

welcome back everyone I'm Caleb Dennison

and I suppose this video was a long time

coming I'm super excited to create this

sort of crash course that explains every

TV type what makes them work and

therefore how they are different a few

advantages and disadvantages to each

also you can make more informed purchase

decisions or you know maybe you want to

pocket some knowledge to pull out at a

cocktail party I don't know maybe that's

just my life anyway for those TV

enthusiasts out there who are just here

for some fun maybe to see if I screw

anything up or for anyone who might be

worried that I'm about to get deep in

the technical weeds and lose you just

understand that I'm gonna make this the

most understandable guide I know how

which will involve intentionally not

getting into the weeds and just

providing the most essential information

and from there if you want a deeper dive

well I'll make some new videos doing

that as well if you want me to which

brings me to my final talking point

before diving in if you have questions

or want to request a video the comment

section down below is the place to do it

I love reading your comments well most

of them plus it helps me meet you where

your needs are so get typing and while

you're down there slap this video with a

like maybe subscribe if you do like and

want to see more business done now let's

do this

[Music]

so to understand where we are and where

we're going it helps a lot to know where

we've been right so let's take a quick

trip back in time work our way through

modern day and then maybe take a peek

into the crystal ball and see what might

be coming in the near future with that

in mind we'll start with the CRT TV also

known as the tube TV this is what

started it all and we were all pretty

happy with it for a little over 65 years

yeah the first CRT TV was made in 1934

by Telefunken in Germany and these TVs

evolve from black and white to color

from Tiny to relatively large and

eventually we're phased out around the

year 2000 give or take they used a

cathode ray tube hence CRT to beam

photons at a screen that was coated with

phosphorus to make a picture they were

very heavy relative to their size and as

we later learned not particularly great

for the environment now along with the

CRT TV we also later got the rear

projection to which back in their day

were more simply known as big screen TVs

these huge boxes used three color light

cannons to project an image on a screen

from behind hence rear projection and

while they provided a very big picture

they were generally a huge pain in the

because you had to keep the three light

cannons in perfect alignment or

convergence or you got this blurry

rainbow looking image and also they

weren't especially bright the contrast

was terrible but we loved it because

they were huge and made it feel like

being at the movies at home then came

the plasma TV and along with it the term

flat screen TV and this is when TVs

basically divorced the 4x3 square like

aspect ratio and moved squarely into the

16x9 rectangular screen shape moved

squarely into a rectangle that didn't

come out the way I meant it to they went

from squares to rectangles okay anyway

plasma TVs had tiny little pixel pockets

of gas in the screen and when you put

electricity to the cast the gas turned

into plasma and lit up phosphors and I

mean plasma TVs were about as futuristic

as it got at the time this whole flat

screen TV thing was a big deal and even

though all TVs today are flat screens

that term still kind of holds on but the

flat screen part of the plasma became

kind of a distraction from what was

really cool about the technology it was

an emissive display so okay time for a

very quick terminology explainer because

this is going to matter as we go forward

an emissive display is a screen whose

picture comes from each pixel lighting

up individually a transmissive display

for the purposes of this discussion is

one that has a backlight or a light

system at the back of the TV that has to

shine through a bunch of layers in order

to get lit up pixels as you can imagine

transmissive displays one with some sort

of backlight tend to be thicker while

emissive displays which don't need any

backlight at all tend to be thinner

anyway when last we left our new friend

the plasma TV it was the flat panel

Pioneer but a lot of work was being done

with LCD screens to make them usable for

TV applications LCD TVs were also flat

panels but but they were way way lighter

easier to move around and generally

considered the coolest thing ever to hit

the TB Market because they were a piece

of cake to mount on the wall now at

first LCD TVs had a compact fluorescent

light bulb in the back shining through

all those different layers so that you

got a nice image on the screen and they

were pretty great they got brighter than

plasma TVs and were just generally so

cool that the public didn't really

notice that they couldn't produce blacks

very well or at all things that were

supposed to be black were really just

kind of a Milky grape but nobody cared

because look how cool it is but then

someone figured out that using the same

kind of light bulb in our TVs that we

used in our lamps was Antiquated and

that is when the LED came into Play We

ditched the light bulbs for LEDs and

suddenly the race to make the thinnest

possible TV was on but also LEDs could

get a lot brighter than old-school light

bulbs so the so-called LED TVs were All

the Rage for multiple reasons and they

still are today now keep in mind this

was still an LCD TV with a backlight

it's just that the backlight changed to

LED so we started calling them LED TVs

instead of LCD TVs much to the annoyance

by the way of dudes like me I am also

annoyed at the term instapot but that's

I'm just going to leave that alone I

already did that rant okay so now at

this point we are more or less at modern

day we've got LED TVs we have plasma TVs

and then Along Comes OLED this was

actually about 11 years ago almost

modern day anyway OLED stands for

organic light emitting diode and in many

ways they were like a plasma TV but

instead of using gas they used organic

compounds that would light up when you

put electricity to them OLED TVs were

way lighter and ridiculously thin

because they didn't need phosphorus or

even glass to contain everything they

were also quite a bit brighter than

plasma TVs if not quite as bright as LED

TVs and the colors were unlike anything

we'd seen on a TV before because the red

green and blue light that they made were

more exact so you could come up with all

these new color combinations and since

then OLED TVs have been at the Forefront

of TV tech routinely winning best TV

Awards year after year from just about

everyone also they started out really

expensive and even though they've come

down in price over time they're still

expensive compared to many LCD based TVs

anyway OLED TVs were so Superior in just

about every way except perceived motion

that plasma TVs died a very quick and

rather unceremonious death rip plasma I

still have one though by the way the

story goes that LG was the only OLED

panel producer around so they pretty

much owned OLED entirely until just last

year I mean you could get a Panasonic or

a Sony or a Vizio OLED TV but LG made

the panels Samsung meanwhile was tired

of LG cleaning their clock with this

OLED business Samsung and LG if you're

not aware are bitter South Korean Rivals

I mean to many of us it's kind of funny

but it is no laughing matter to them

corporate Espionage is a real thing

anyway Samsung was like you know what we

know our LED LCD TVs are brighter and

we're getting better and better at the

black levels we just need to take the

color to the next level so we can claim

that our TVs are better than OLED TVs

and then we'll get a bunch of other

brands on board with using it and then

it'll be everyone against LG and thus

the qled TV or qled TV was created the Q

in qled stands for Quantum dots Quantum

dots are tiny nanoparticles that glow

with great efficiency when you shine

light on them and Samsung uses them to

make its LED backlights even more

powerful so qled TVs got brighter more

colorful with brighter colors and then

Samsung marketed the crap out of qled

and said you know anyone else can do

this if they want to to you can use the

term qled too let's just take the TV

Market over with these things well that

didn't exactly work because as bright

and colorful as qled was it still had

this one Achilles heel that reviewers

and critics like me just could not get

over and that was backlight blooming

Halo and generally not great black

levels so OLED being enemies of display

is more or less perfect in those areas

those are all transmissive display ones

with a backlight problem so then how do

we make the backlight better mini LED

yes let's take the area backlights that

we're using in qled TVs and make them

way tinier and then use way more of them

we will Master black levels eliminate

blooming and Halo through sheer brute

force of numbers and so we have the mini

LED TV it's still in LCD TV it's still

backlit it's just a much more refined

backlighting system also Quantum dots

are still involved so they are mini LED

qled TVs I know I know I'm sorry don't

shoot the messenger okay so let's just

like frame this as in where we are today

so we have LED TVs which are decent

quality TVs that are ridiculously

affordable but don't have especially

great performance when it comes to color

contrast and motion then we have qled

TVs which are more premium with higher

overall brightness more accurate color

as well as brighter color decent motion

resolution and generally solid contrast

and backlight control but you still get

a little halo effect or blooming around

bright objects on dark backgrounds then

we have mini LED qled TVs which are at

the top of the LCD TV or transmissive TV

food chain these are the most premium

LCD based TVs they can get incredibly

bright have excellent HDR performance

and the best contrast and backlight

control available along with Vivid

colors and very good color accuracy

still there backlit so you may see

backlight fluctuations a tiny little bit

of blooming or Halo but usually not much

now as the industry is increasingly

embracing mini LED backlighting as the

norm we may see more variations in how

many LED TVs perform right now they're

mostly just premium but generally

they're the best you can buy when it

comes to a backlit TV then in the other

camp we have OLED which requires no

backlight at all offers excellent

contrast near perfect black levels

incredible color accuracy and saturation

and can get sufficiently bright for most

situations these have been and continue

to be the preferred TV for dedicated

movie rooms or entertainment spaces

where you can control the lighting in

the room or if you just want the best

looking TV but now we have two new kinds

of OLED TVs to get familiar with there

is the new MLA OLED and QD OLED both of

these are basically brighter OLED TVs

and they come at a premium them as

regular OLED TVs continue to drop in

price I'll have another video soon on

how MLA OLED and QD OLED are different

and what the advantages and

disadvantages are for each but to keep

things simple just understand that OLED

now comes in three flavors all of them

very premium they're standard OLED MLA

OLED and QD OLED so if we're adding them

all up that's six types of TVs to choose

from so okay we're done now right we're

good for a bit nothing more to worry

about learning well yeah you're good

until next year maybe yeah sorry TVs are

still evolving so if you want to have

the latest and greatest we've got a

couple more Technologies coming down the

pipe in the coming years slowly making

its way onto the scene now is micro LED

you're welcome now you might think this

is another backlit display because it

says LED where the back lights are even

tinier than mirror mini LED but that's

not the case like OLED micro LED is

another kind of emissive display makes

its own light no backlight but it is the

brightest emissive display of all so it

has the perfect wax and amazing contrast

but that contrast is cranked up to 11

because micro LED can get so incredibly

bright like almost blindingly right the

downside to micro LED for now and the

reason you're not likely to see it for

sale on the floor of your preferred

electronic store is that it is super

expensive and it's really hard to get 4K

resolution at normal screen sizes

because the pixels aren't as Tiny as

they are on the other types of TVs we

talked about the other interesting thing

about micro LED displays at least for

now is that they're modular which has

its upsides and downsides see again just

for now anyway micro LED panels are

these smaller squares and you can stitch

them together to make a display of

varying sizes and shapes that's

flexibility and that's a good good thing

but the downside is that there are seams

and while you can't really see these

seams between these panels when the TVs

are super bright at least not from a

normal viewing distance you can see them

when they're dimmer at least if you look

closely enough now until this last

January most micro LED displays were

basically the size of an entire wall but

they're being scaled down to normal TV

sizes like 55 inch and 65 inch screen

sizes so we'll see where micro LED goes

this year but I still think we're a year

or two out until these become

competitive with qled or OLED and

finally if you dig deep enough while

doing TV research you could hear about

emissive quantum dot displays these Go

by different acronyms I'm not going to

run through them all but the idea is

that the quantum dots that are currently

used to enhance existing TV Technologies

might become an emissive display Tech

all on their own and if they do

wow they could be really amazing but

like all new TV tech will want to see

how they perform and we'll need them to

come down in price for a few years

before you would ever want to consider

buying one unless you're just made of

money and like to show off having the

latest and greatest stuff which if

that's you no judgment just just say it

so that's my little history lesson and

state of the TV industry all wrapped up

into one video I hope you enjoyed it if

you need to refresh your memory on

anything we'll have timestamps down

below for each TV type so that you can

easily review Thanks as always for

watching everyone hope you found this

video both fun and informative if you

did and even if you didn't would you let

me know down in the comments below then

I'll know that you actually watch the

whole thing and might like to be able to

say things don't forget to like And

subscribe while you're at it I'll see

you on the next one and until then

here's two other videos I think you
