I am looking for a display that is similar to the Nokia 5110 but bigger.
I have the following requirements (edited):
The display has to be around 3 inches.
It should be readable in the sun.
It should have a low power consumption.
It should have a refresh rate of at least 1Hz.
I do not really care about the resolution, from what I have read is that everything that has a resolution of 128x64 or lower is cheap. This resolution is fine.
Color is also something I do not care about, a monochrome display is fine.
I hope someone can help me with this!
Edit:
I realise now that I should have been a little more specific. What I want to do is make a 'rowing coach'. It should show the current speed of the boat, the stroke rate, distance travelled and the heart rate. I want to divide the display in four sections, in each section I show one of the types of datas measured. The data measured should update at least every second on the display.
I made a quick sketch that shows what it would look like on a 128x64 display:
1 second updates will be quite annoying though, I bet. Would be ok if it's 10 second updates or so.
Does it have to do graphics or would for instance a 20x04 LCD also work (you can of course create a limited set of custom characters to fake simple graphics)?
I've been working with a wide variety of displays and can recommend two different ones for this use case. Not quite 3", but there's the Sharp memory LCD (2.7" 400x300) and a lower cost 2.13" 250x122 ST7302. Both use very little current while active (<25uA) and look great in any light. Pictured below is the ST7302.
I agree with post#2, e-paper or e-ink displays for low power and my Kindle works very well in bright sunlight.
I'm using a 4" e-ink display with one project. An Uno will be hard pressed to drive an e-ink/e-paper display as they are quite ram intensive and the libraries are big.
