2.3 cm (0.91″) 128×32 Blue OLED Display Module with I2C/IIC Serial Interface OLEDs are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCDs and LEDs.The most attractive thing about using 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 0.91″ 128×32 Blue OLED Display Module offers 128×32 pixel resolution. They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors. This OLED Display Module is very compact and will add a great ever user interface experience to your microcontroller project. The connection of this display with microcontroller is made through the I2C(also called as IIC) serial interface. The 0.91″ 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 offer a very wide viewing angle. This product knows as I2C Interface, Display, OLED, OLED Display, 128×32, 0.91″ OLED, OLED, OLED Display Module, 0.91″ I2C Serial 4-Pin OLED Display Module.
