Sunlight readable displays
Sunlight readable displays
(OP)
There are many display panels that claim to be sunlight readable. They give the display intensity ranging from ~ 700 nits to 2100 nits. However, I have not yet found a specification that defines sunlight readable.
What are the parameters and levels that define sunlight readable?
Do display reflectivity or light intensity from the surrounding area play a role?
Is there a specification?

RE: Sunlight readable displays
Chapter 6 is about contrast enhancement.
I use reflective LCD displays in a recent application. They have a fantastic contrast, but the ones I use cannot be read in total darkness. But, then again, it is difficult to work in darkness, too.

RE: Sunlight readable displays
Were you able to find an answer to your question? Reflections and refractions cause LCDs to be useless in bright ambient light. Some manufacturers will add AG or AR to improve sunlight readability but the only solution is to use direct optical bonding. There are lots of standards for measuring the quality of direct optical bond. Resistance to UV light, operating temperature, fog, etc.
I can help in that department, let me know if it is still an issue.
