Point taken. Any suggestions on how I can fix this? My guess is the system-gschemrc file is a type mismatch. However, I don't want to guess anymore. On 8/9/07, DJ Delorie <[EMAIL PROTECTED]> wrote: > > > A could of quick pointers... > > > And here's the directories I created in my home director

On the subject of displays. Life time is not only measured to half brightness it is also measured to where non-uniformities become obvious. So a color display's life can be over when one color fades quicker then another or where the screen image starts to become blotchy. Humans tend to be very sen

The contrast ratio also has to take into effect ambient light. So unless the oled absorbes all incomming photons (no reflections) then it isn't infinite. Ok maybe in a cave. Steve Meier DJ Delorie wrote: >> How is this possible, when OLEDs have been shown to last longer than >> incadescent lightb

The problem with using LCD-based displays is that this is going to be in a dark room next to the bed I sleep in. I really don't want the glowing grey rectangle effect that LCDs have. The OLED display was ideal because it's LED based - the black is *black* and the digits are only as bright as nee

I hooked up the bigger OLED to the protoboard today, and it didn't work. Much panic ensued. It turned out I had SDI and SCK swapped in the symbol. A simple wire switch and it worked fine, tweak the schematics and board and continue. Had I not done this test, I would have fabbed the board and h
