I have a similar question:
Which display has (in general) more contrast in normal daylight and indoor lighting. The transflective or the reflective display?
Can I use the transflective display in "reflective mode" by switching off the backlight? Will the contrast of the display be similar to that of a reflective display? Or will I loose contrast?
It seems to be quite difficult to find a reflective display for my requirements.
(see

Therefore I am thinking about useing a transflective display. What are the disadvantages? Higher current consumption?
