    I picked up basic white LEDs ... am I better off using colored ones such as yellow?

    As an update .... I've tried lighting the LED from different angles with different types of light, as well as using different filters as a last ditch effort (polarizing and different colors) ... with no luck. I picked up some LEDs and a transformer and will try the DIY makeshift backlighting approach as suggested and will let everyone know what happens.

    I'll look into the LED option which could work ... any suggestion on the type of LED's to use? In terms of zooming, I've tried but the glare effect is still present. Thanks!

    Unfortunately there is no backlighting available on the display

    make that a 7-segment monochrome display (black segments)

    Hi everyone, Thanks for all of the questions and thoughts. I should have clarified upfront that this is a 7 segment LCD display (black segments) that is house in a control box which manages a piece of equipment. (I mention this last part only because I don't have the skills to tap the source which is feeding the display ... it's on a control board). I've tried different viewing angles of looking at the display, but it's not working. (Trying different did work on another display, but not this one) What I'm going to try next is to apply some anti-glare film to see if it helps. I'll reply back with the results Thanks again!

    Slight type ...near the end it should read "camera is looking at the LCD display" instead of "camera is looking at the LED"

    Hello everyone. I have a bit of a tricky situation. I would like to use a remote camera to read the LCD display on a piece of equipment in an unlit room. The characters on the display are about 3/8" tall and 3/8" wide, and are in the dark. I've tried using the built in IR illuminators on the camera as well as some ambient lighting (which I can remotely turn on), but everything is washing out the display (please see attached image, the display looks more recessed behind the front window than it actually is). In other cases, I've had luck by changing the angle of incidence in which the camera is looking at the LED, but it's not working in this situation. Is there a filter I could use? Any other suggestions? Regards, Raymond
