Best Display under hard direct sunlight?

by dreamstarusa on Tue Jan 09, 2018 4:56 am

Hey guys,

I am working on a speedometer for motorcycles which will require roughly a 3.5" display (I'm flexible on this). I'd like to know which display is best under hard CA direct sunlight. I have done tests with small OLEDs and it was very good in broad day light, but when I went under direct sunlight, it was not good enough. I'm assuming reflection is also an issue.

I just saw your E-paper displays and right away I thought it would be amazing for my use, but then I searched and realized you cannot do real-time displaying such as of a speedometer. Is this correct? If so, do we expect the technology to improve to do real time soon?

What display would you guys recommend for my application?

I have not decided on the micro-controller yet, so this should not be considered at this point. I will pick the controller after picking the display.

Any comments is dearly appreciated.

Max

I've got a Papirus on order so no direct experience. Still, check out the final two animations in the video below. Depending on how your wants it might be fast enough.

Dear Mike,
Thank you very much for the link. It does look good at 100. I am assuming they are milliseconds? Yes, I am a complete newbie and I am learning slowly. If so, 100ms (1/10th of a second) would be fast enough for me.

So, now the only question is : what is considered PARTIAL? or rather is 100ms possible for 40% to 60% of the screen utilized for example? In the case of my speedometer, the numbers displayed (the SPEED) will be really big - as to be seen by a motorcycle rider in fast and dangerous motion. So if the rider is going 65 MPH, the number 65 would be really big and probably take a fair amount of the screen size.

What are your thoughts?
