Sunlight viewable LCD display?
« on: January 28, 2020, 10:34:10 pm »
I was wondering if anyone had experience with retrofitting a normal 20-odd inch computer LCD display with an eye-scorching LED backlight.
I was trying to use a normal 20-odd inch LCD for a public display.
Even in the shade a stock LCD isn't that visible.
I think the one that I'd try is using CCFLs right now.
The uniformity of ilumination wouldn't be that critical.

I've had LCDs apart before, checking the image when the backlight died.
I've thought about making it open back to directly use sunlight, but that gets messy.

Not done that... But I've bought sunlight readable panels before.
As a rough figure, I'd say 1000 cd/m2 is the very minimum to get something usable.

Mmm, I'll bet those are more expensive than the displays that I pick up at a charity shop. :P

Definitely.
The only reasonably priced ones I bought were 7", but still not cheap. The larger ones were very expensive.
