I guess you forgot to scroll down to the part where he said "I got my first and only white on blue from adafruit. It was slow and needs back light in well-lit indoor environmenit "
I guess you didn't realize that this is a conversation about white/blue lcd in OUTDOOR environmenit, not INDOOR environmenit.
On that front, liudr said:
But if I turned off the back light, I can see outdoors.
What he said about INDOOR environmenit is probably irrelevant to this discussion.
Sounds like liudr wins and you lose.
Here's a quick and dirty comparison
I guess there is this possibility that liudr has superman vision.
But without a picture of his white/blue lcd outdoor, we can never tell.
