Changed:
Under inside conditions, black on white looks great, with widest viewing angle range... I'd compare it to VFD. In direct sunlight however, the transflective black on white display looks better, and it doesn't matter how bright the sun gets - I've ordered another one so I can check it with a working backlight. In the car at night, I expect most folks (at least, those who don't drive convertibles) would prefer the white on black... but it's always a compromise.

In direct sunlight however, the transflective black on white display looks better, and it doesn't matter how bright the sun gets. For most folks, the transmissive STEP display looks best (green backlight is also an option). If you expect direct, bright, sunlight, transflective is tops: it's great in direct light, and is still very readable even if 50% bright and 50% shaded.

Also, Read The Fine Manual - I assumed 5V Optrex LCD had a 5V LED backlight like the standard display, but it didn't. So no test of the backlight on the transflective STEP display (it looked good for the 15 seconds before it burned out)
There could be room for subjective improvement by adjusting the contrast and brightness too.

Also, Read The Fine Manual - I assumed first Optrex transflective LCD had a 5V LED capable backlight like the standard display, but it didn't (it looked good for the 15 seconds before it burned out). I used a simple potentiometer the 2nd time, but a voltage divider is a better solution.
