2.32 cm (0.91 inch) I2C/IIC 128x32 OLED Display Module - Blue Color offers 128×32 pixel resolution. They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors. 

OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.

The most attractive thing about using the OLED displays is that they do not need a back-light like conventional LCD/LED screens. The organic material itself has a property known as Electroluminescence (EL), which causes the material to “glow” when stimulated by a current or an electric field. Best energy saving displays ever!!!

This OLED Display Module is very compact and will add a great ever user interface experience to your Arduino project. The connection of this display with Arduino is made through the I2C(also called as IIC) serial interface.

The 2.32 cm (0.91 inch) I2C/IIC 128x32 OLED Display Module - Blue Color produces blue text on black background with very good contrast when supplied with DC 2.8V supply. The OLED Display Modules also offers a very wide viewing angle.
