Title: OLED display works!
Post by: 6581punk on April 19, 2012, 06:56:24 PM
I've swapped my LCD for an OLED and it worked fine. So fast and clear. The only downside is the bezel is much smaller, so I need to have a new one made.

Only one other tiny downside, the LCDs show a blank pattern on start up, this is completely black and shows nothing. So for a few seconds it looks like the Preen isn't working.

I got it here:

Nice  :D
I've never seen an OLED character display execpt on pictures.
I may order one at some point.

I cannot find its size on the PDF.
If you put the thin blue part around the LCD, is there an empty space ? Or doesn't it fit at all ?

They are well worth it. The viewing angle is brilliant, if you can see the screen then you can read it. Plus you don't notice how slow LCDs are until you've seen OLED.

Here's the difference, OLEDs are much thinner and the bezel is smaller as there's no backlight.

Nice.  Time for me to build some preenage.  Anyone game for some black acrylic cases with windows? This uses the same scheme as shruthi so there will be enough space with an OLED

I had a red translucent case made, but a screwed up the measurements slightly so had to file it.

But you are right, probably no need to have the display angled with OLED.

Same tacts/buttons/encoder heights as the shruthi and sammich stuff so it will fit.  Happen to have a bunch of 4x20 Newhaven parts that were destined for MB6582s but they dont seem to work in 4 bit mode so I never used them

Upgraded here too, well worth the while.

Just ordered a yellow OLED display !  :D

Seems like i'll have to make new plastic parts to fit the new screen size.

I don't think I would include one in the kit. Plus they're also supposedly shorter in life, they burn out like old CRTs did. But that's not really a problem on a DIY kit.
