Hello all,

I think I may have run into a problem. I was taking apart my LED TV that I plan to use for a 46” DSI setup when I discovered that my TV is edge lit. I definitely could have looked at the specs before hand and seen this, but now it is done. Is there a way to still use the TV in the setup? If so, then I don’t seem to understand exactly how my layers would look.

I can try and take some photos if it helps.

Thanks in advance!

photos would help. I imagine you can still use the lcd matrix. You’d just need to lose the reflector panel behind it and get a back light for it.

Thank you for your response.

I have attached a couple photos here. I took pictures of the parts I thought were relevant, but let me know if you’d like to see other parts.

One photo shows the whole inside (everything beneath the outer polarized glass). The second photo shows the leds that surround the top and bottom edges, and appear to shine into the top sheet of acrylic (or whatever material that is on the top in the first photo).

What confused me is the white sheet behind the acrylic. Would this be the “reflector panel”? Also, what type of backlight would you recommend for replacement? I have a backlight from a broken 42” LCD that seems to still work, would that be useful for my situation?

Thanks!

The type of backlight shouldn’t make the TV more or less capable in being used for a camera-based tracking setup.  Most people discard or add additional lights to their backlight setup anyway as distancing it from the LCD matrix diminished its brightness.  To increase the brightness just add some white LEDs and make sure it is all diffused with one or two of the white layers on the backlight currently.

Hi,

Can someone please tell me if I have to remove the white paper behind the acrylic? Camera won’t see through this paper.

No, that is the diffuser and you need that. There may be multiple sheets though so you should experiment to see which layers produce the best results.
