5 Minute explanation - How does an LCD projector work?

[@borayurt66]

Yeah, I knew there was a tiny but high res LCD screen inside, but I always thought it would be a full color one. Never knew about this. Good info. Thanks!

[@AlluringPegasu13]

So it isn't? Does each lcd only show their respective colours? Or they don't have colours?

[@usamimizuki]

POV: you search this because you can't sleep thinking about this.

[@mikekaye3874]

Enjoy it? I freaking loved it. Finally...in like 5 mins, you explained what most who take 20 and still never fully understood how it was done. I still have some fine detailed questions but wow. Thanks bud. You know what it is, it's the last step, how the three colour separated images are combined into one as it goes to the lens. That's what I would like to see how it's done. This is great. - Toronto, Canada.

Thank you Kris. I am watching this video with my IGCSE Computer Science Class. We learned so much and enjoyed your jokes.

[@KrisCochrane]

Ha! Brilliant. Where are you located in the world?

[@phonvyr]

@@KrisCochrane Morocco. I hope you are safe!

[@zxshark8651]

Kris Cochrane it’s weird that you ask people where they are lol

[@KrisCochrane]

Didn't really think it was weird - I was curious as I'd never heard of an IGCSE before.

[@romanyrashed9689]

me too

[@mikebedford8494]

nicely done - showing the splitting of the 3 colours was really good.

[@childscraig]

Cool vid, have never opened one of these, have always wondered how it was done, cheers for enlightening me!

[@PRKPHMUHAMMEDAFSERN]

WOW! That was a lovely one. Thank You So Much!

[@budiononfs2117]

Thanks for the great explanation

[@saemranian]

Perfect, Thanks for sharing.

[@AtOddsAlways]

Best explanation I've seen to date and nice and simple! Good work, Mate!

[@samuellin9217]

Excellent explanation

[@ficinoninovillaflores8614]

nice explanation

[@okapinoodlepiper5417]

Thanks for the video

[@KrisCochrane]

No worries!

[@maas1728]

Nice explanation bro thanku

[@whitigir5019]

So better light source and better panels will make a better projector ?

[@verndexter]

THIS IS SO COOL!!!

[@BRENDAN28]

So how does this project a certain image? So if you get a transparent LCD screen and shine a light at the back of it and then send the screen your image is how it would project it?

[@lucelxebinog]

Explain thh3 "almost like a metamaterial" color Collimator. Show it.

[@sugiyarti9409]

please explain about the polarization of light hitting the lcd panel... why is there no or very few youtube channels that discuss it why?? because it is useful for those who want to repair the damage to the projector..because without polarization 3 lcd will not work

[@waynestewart1919]

That was great. So they are just monochrome LCDs with the light filtered coming to them. {Admires Scottish accent realizing it actually helps in attention as-well-as retention.}

[@malcolmhollett8638]

Cool vid

[@ludiezhu5314]

Would you please tell me what company and brand of projector is used in this video, I want to buy one to do some experiments，thanks 。

[@theempowerer5718]

he said it was an old Mitsubishi

[@nexus1g]

"Now of course we don't want to just watch blue footage..." *_Picasso has left the chat._*

[@Ziggerzzz]

Why can't they use a single rgb lcd ? Heat maybe

[@korishan]

I imagine it's due to density. After all, they are taking a 2 inch (thereabouts) screen and turning it into 16 ft. If they incorporated all the leds into 1 screen, the resolution wouldn't be as sharp. With this method, each pixel truly is 1 pixel, not 3 separate pixels that are so close together they look like one on a small scale. Blow that up onto a huge screen, you'd probably see each of the 3 led pixels. That's my best guess at the moment.

[@dharan.5285]

I have a Cannon LV-7265, there is a background flicker of red but no red on the image. What can i do here?

[@davelongworth361]

I'm going to make an led conversion, any tips?

[@PhoxUwU]

great video! just so you know though, green is not a primary colour ;)

[@KrisCochrane]

You're right!

[@NautilusCrypto]

Love the accent!

[@NehemiahDC]

So there isn't a tiny bird making shadow puppets and saying "It's a living"?

[@MuhammadYaseen-vx5hw]

video is heart touching. but some problems having with my projector so please can i write a email to you? for resolving them.

[@trendyprojectors4743]

But general people can't understand the circuit board you shown.... the person needs to be tech savvy...

[@sebdouse6970]

People invented this...what
