Hi all,
I am fascinated by the project of turning TVs into "Realistic Artificial Daylight"
https://www.youtube.com/watch?v=8JrqH2oOTK4
They use old LCD TVs with a Fresnel lens to create parallel light, which apparently gives off the effect of very realistic daylight.
I might be able to get a broken 65 inch LCD TV from a friend (panel glass seems ok).
But before I take all the effort of transportation and disassembly, I wanted to double-check: do all LCD TVs contain the Fresnel lens? The guy in the video says that very old or very big might not.
The TV is quite big with 65 inches, and it also has an "HDR" feature, which - as I understand - means it must have bright background lighting.
I'm wondering if it still has the LED backlight from the side of the frame, or if it might have lots of LED strips on the back - but might leave out the Fresnel lens, and would be unsuitable for the project.
Any insights are highly appreciated.
Thanks,
Holger
