Hi all,

I am using OS128064PK27MY0B00 OLED i had a confusion in using internal VCC.
Is it necessary to use external supply for VCC or is it possible to use internaly.If so how to use 12V by internal supply.

Regards,
Vinu
 

Hi

For OLED display you need to use dual power supply low volatge for the logic circuit and high voltage(12-18V) for the LED driver.

Some OLED driver ic have internal boost converter who you can use to create the high voltage ,otherwise you need to produce high volatge externaly by using a boost converter (see TI site for OLED boost converter)

All the best

Bobi
