You needn't bother. Having repaired a considerable number of displays with dead backlight inverters, I can say from experience that you won't be able to see anything.
(Light has to pass through an LCD in order to produce a perceptible image. Watch displays, pre-backlight Palm devices, non-backlit e-ink displays, and the like do this by reflecting back light that arrives through the screen. Computer displays all but universally do it with a backlight; without one, and without a reflective layer behind the LC layer, you see a blank black rectangle no matter what the crystal layer is doing.)

You'd be surprised. Getting good light reflection without also producing an image of the surroundings to conflict with the display is harder than it seems.
