OLEDs are the future of displays, as they possess some of the greatest advantages over both the conventional display technologies of LCDs and LED.
The most attractive thing about using the OLED display is that they don't need a back-light like conventional LCD & LED screens. The organic material itself has a property known as Electroluminescence (EL), this causes the material to “glow” when stimulated by the current or an electric field. This is the Best energy-saving displays ever!!!
Here 0.91 inch 128×32 Blue OLED Display Module offers 128×32 pixel resolution. They feature much less thickness than LCD displays with good brightness and also produce better and true colors.
These OLED Display Module are very compact and will add a great ever user interface experience to your Arduino projects. The connection of this display with Arduino is made through the I2C(also called IIC) serial interface.
Here 0.91 inch 128×32 Blue OLED Display Module 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 which is best in the industry.
