easily viewable cheap LCD in bright glaring sunlight? Answered
I recently bought the cheapest screen I could on amazon for around 20 or so dollars for use on my quadcopter, it is a really crap quality display (only 480 x 272 resolution, and very poor color reproduction, viewing angles, and contrast) but it does serve the purpose of a FPV display for my quadcopter.
However, I remember my old faithful flip mino camera as well as my old palm centro phone which had some type of semi-reflective LCDs on them! The displays could easily be seen in direct sunlight even with the brightness set to the minimum! They seemed to work a bit like calculator LCD displays, where they work on a basis of reflection, but also have backlights in them. To verify that the display on that flip camera does indeed reflect light back, I charged it up and turned it on with my 2000 lumen LED torch shining directly at it. images on my GS3's AMOLED panel would only be visible with the brightness cranked wayyyy up, and similarly on most LCD displays. They just could not handle the same way the flip camera did! You could clearly make out a picture on the flip camera display even when it was charging and the backlight was 100% off!
What would I be searching for to find a display with a composite video input capible of being viewable in direct sunlight like this? Might it be possible to modify my current LCD to make it more viewable in direct sunlight?
