I took apart a giant projection TV and there were a bunch of these lining the screen mount. (lemmy.world)

I feel like they probably have something to do with light level detection or infrared signal receiving but I genuinely have no idea. They could just as likely be part of the sound system for all I know.

IR receivers for the remote

I just wonder why they are covered and face inward. The shiny part is pointed towards the inside of the unit.

I guess I should find out what voltage they operate on and see if I can use them in some tiny project.

Edit: thanks!

Why would you need more than one IR receiver for a remote control?
