I originally had a 20x4 green backlit with black character lcd display. In daylight I could not see the backlight but the display was readable. I need more information on the display so I was thinking of switching to 128x64 green backlit with black character GLCD display. But have found other altern…

Here we go, not in the brightest of sunlight, its winter here, and there was a slight bit of haze in the air. First is display pointing at sun, displaying is text as you cannot see. Second is display pointing away from sun so in shade. [Pointing at Sun] [Shaded from Sun]

I still have several of those TFT displays, do you want me to count how many I have ?

I would be thankful to you if you could post a pic of working display in daylight, a demo program would be okay

Are these photos with backlight LED on?
