Start with an old display such as an old cell phone LCD, Find the leads that power the screen back light. Solder an old USB cable to the leads, plug other cable into powered USB port, find a conveniently sized magnifier lens. Find a polarized film or 1/4 wave film (you could cut the polarizer off an old cell phone, lap top or LCD display), Place polarizing film above magnifier and the cell phone screen below lens.
