Enclosure for blind display
Enclosure for blind display
(OP)
Hi,
Context - The produuct that I am working on currently requires a blind display. They have LEDs on the back side with stencil on top of it, that creates graphics and projects them on to the white plastic. The display is visible only when the unit is turned ON. Else, it is a plain white plastic top cover.
Here are some example images.
Most commonly these are seen in Air conditioning units.
My question - What type of platic can we use for this top layer (ABS, PP, PMMA or other)? Will painting the part make it opaque to LED lights?

That aside the effect is optical so it doesn't care what material you use, it just has to be properly opaque to make the effect work.
I believe many different plastics would fit that requirement which is good. Select the plastic for other mechanical and cost reasons.

Your part will not work unless it is translucent. You can use translucent paint, possibly on a transparent part.
After this, you need to ask practical questions.
