sorry for being so late, i was on my business trip for the whole week.
@Progen, actually i was in ShangHai last week, i’m just for fun, i have worked for many years, 
, i’m very interested in the new staff and i worked in electronic buiness. by the way i’m in Shenzhen.
i have tried PVA & water solution to glue the projection screen to acrylic, seems fine, but i’m afraid the long term reliability, i just got the PVA glue from the stationary store, also i got a tube of liquid glue for paper gluing, seems better adhesive strength. any way, it worked and i got a really sharp projection image than frosted glass or window film. sorry i can’t post the picture because i just left all of the staff in one of my friend’s apartment. i will start to do a new final products.
