OCELL is a 0.5 inch OLED module designed as a Arduino shield and also available for other micro controllers . It is the smallest Arduino display module you can find so far.
You could connect it to Ardunio micro directly without doing any PCB layout and also available for other controllers . It is a good choice for a DIYer to make a project which need a tiny COOL OLED display.
The smallest size in all Arduino display modules so far.
Very high contrast and brightness.
Very low power consumption
No backlight required
Supported by U8glib library
These OLED displays are small, only about 0.5" diameter, but very readable due to the high contrast (450cd/m^2 brightness). This display is made of 60x32 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast and very low power consumption.
This is a very nice display, enclosure of the project under construction
Very Delicate Be very careful with these displays. I bought 2 and neither one works anymore. Near as I can tell it was probably my handling of the display itself. I did not permanently attach the display to the board right away. I wanted the ability to install it under other circumstances but I think the connection between the controller (metal can) and the glass display lost its connection. I was able to temporarily get the display to work by squeezing it at the connection. If I buy more I will have to try and secure the connection with epoxy (between the little rectangular block and the metal can to the right of the flat cable) before subjecting the display to movement.
