There are two sorts of reflectors. A specular reflector (mirror) preserves any image in the light that falls on it. A diffuse reflector (paper) destroys any image information. So, if there's not already one there, a reflecting layer of white paper would help. A mirror-like sheet of mylar would help too, but might cause some ghosting. A lot will depend on the distance between the LCD and the reflector plane. -- Dave's Engineering Page: http://www.dvanhorn.org Got a need to read Bar codes? http://www.barcodechip.com Bi-directional read of UPC-A, UPC-E, EAN-8, EAN-13, JAN, and Bookland, with two or five digit supplemental codes, in an 8 pin chip, with NO external parts. ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
