Quoted from Purpledrilmonkey:This is news to me. No Stern I've seen comes standard with white DMDs to my knowledge. AFAIK only Xpin makes white LED DMD displays.
The red lighting gel helps obscure the segmentation of the LED blocks and softens the lighting from each LED. Without the gel it looks exactly like what is - a bunch of ugly LED blocks soldered to an equally ugly board.
No it's not white. It's orange. My IMVE had a red filter over an orange display. It's not red on white. He's wrong. But hey, say a wrong thing with enough conviction and people might believe you.
Oh I forgot to add, Duh
