Hi there. If there is to be a back projector system behind a screen (such as a car instrument panel), in order for the information to be displayed in the correct sequence I'm thinking some sort of horizontal/convex lens will need to be used in order to invert the information in the horizontal plane so that it is displayed in the correct sequence to the user on the other side of the screen. Is there anything else (or any comment on the description above) that should be considered in order to produce the correct sequence of information? Any help is appreciated. Thanks!
