Can you handle mounting OLED display within 2 seconds?

Mounting of a small graphic display EA OLEDS102 which is mounted only by soldering into PCB or plugging into a socket is not only fast and reliable but also cheap.

Are you also dissuaded by relatively laborious mounting of common display modules by screws or tapes/glue? Solution is a well-known series EA DOG. In addition, company Electronic Assembly also introduced 2 types with the same mechanical advantages but in OLED technology.

You are probably familiar with the OLEDL128-6GGA module from our recent article and newly it has a new sibling.

It is the OLEDS102-6LGA which, as a younger member, is naturally also smaller : )

It is only 2.4 mm thick. Resolution of 102x64pix enables to display 8 rows with 17 characters or 4 rows with 12 characters of a bigger format. Control is handled by SSD1306B controller and it enables to control the display via SPI or I²C interface. The content is yellow and as we know it from other OLED displays, the black is really “black”.

OLEDS102-6LGA maintains mechanical compatibility with EA DOGS series. Pins usage is however naturally different.

An alternative in a form of an OLED display brings another benefits, mainly:

- great contrast of approx. 2000:1
- extreme viewing angles on the border of physics laws
- reliable operation and fast response (microseconds) even in frosts

Although OLED displays don´t technically belong to displays with extremely low power consumption, they still have advantages in comparison to standard LCD displays with backlight, because only pixels which are ON consume power. In case of standby operation of your device when only a few characters/ icons will be displayed, overall power consumption of the display is also relatively very low.

Displaying of the new OLED EA OLEDL128-6GGA can be tested using the  EA USB9781-USB testing board and the EA startoled.exe software (free).
