    Unfortunately, the high ambient light fidelity of current transmissive modulatory LC displays is unlikely to increase significantly in the short term due to ambient light diffusion and contrast between voltage-on and off pixels. (the backlight still transmits even when all orthogonal liquid crystals are in the voltage -off state..)

    Apple currently uses an LED backlit in-plane switching tft transmissive lc display for it's mobile products. Sunlight readability could be improved slightly if Apple switched to an emissive display, such as OLED, like Samsung's active matrix and "super" active matrix display technologies, but fidelity would still not be comparable to a transflective or reflective display.

    I'm reasonably certain at least part of that post was in English.... LOL As if I didn't feel out of touch with regards to technology before.....thanks TDM! LOL
    Unfortunately in science what you believe is irrelevant.

    There are a couple simple things that you can do depending on where the device is located. I run into this as well with any device I have mounted to the yoke of my plane (Piper Archer II). While I don't have one on my iPad, an antireflective screen protector helps. Works well on my iPhone, for sure.

    The other thing I noticed, direct sunlight not withstanding, is that if I'm wearing a light colored shirt, the light shining on the screen keeping me from seeing it as well is actually being reflected off my shirt. I found that if I wear a darker shirt (one fellow I know of actually has a black "bib" that he wears while flying to minimize glare - not for me, though) the reflection is greatly minimized.

    I realize that if you fly in a fishbowl-type aircraft like an RV, CX-4, or anything else with a bubble canopy, the last thing you're probably going to want to do is dress in black! My iFly 700 has a nice sunshade available for it, but I'm not sure how feasible that kind of device would be for an iPad, though. A quick Google search turned up this guy:

    Seems a little (lot) bulky for an aircraft application, but wonder if something similar could be fashioned.
