0.91 inch Blue OLED Display Module This 0.91 inch Blue OLED Display Module has a resolution of 128x32 pixels. They are much thinner than LCD displays with good brightness and produce more accurate and true colors. This OLED Display Module is very compact and will enhance your Arduino project's user interface experience. This is an I2C OLED display, The I2C (also known as IIC) serial interface is used to connect this display to Arduino. OLEDs are the future of displays because they have some of the most significant advantages over both conventional display technologies, LCDs and LEDs. The most appealing aspect of using OLED displays is that they do not require a backlight like conventional LCD/LED screens. Electroluminescence (EL) is a property of organic materials that causes them to "glow" when stimulated by a current or an electric field. The most energy-efficient displays ever!!! When powered by a DC 2.8V supply, the 0.91 inch 128x32 Blue OLED Display Module produces White text on a Blue background with excellent contrast. The OLED Display Modules have a very wide viewing angle as well. If you want to use this OLED display module in your Arduino project, for that you will need few essential components like Jumper wires Breadboard Batteries or power supply Pin Description: GND: Power ground VCC: Power positive SCL: Clock Line SDA: Data Line

0.96in 6 pin OLED Display This is the 0.96 inches (2.44 cm) OLED Display Module is a precise small, This OLED module can be interfaced with any microcontroller using SPI protocol. It is having a resolution of 128x64. OLED (Organic Light-Emitting Diode) is a self-lighting technology that consists of a thin, multi-layered organic film sandwiched between an anode and a cathode. OLED, unlike LCD technology, does not require a backlight. OLED has a wide range of applications and is widely regarded as the ultimate technology for the next generation of flat-panel displays. The basic structure of an OLED Display Module is made up of organic materials sandwiched between the cathode and the anode, which is made of electric conductive transparent Indium Tin Oxide (ITO). The organic materials form a multi-layered thin film that includes the Hole Transporting Layer (HTL), Emission Layer (EML), and Electron Transport Layer (ETL) (ETL). By applying the appropriate electric voltage, holes and electrons from the anode and cathode are injected into the EML. Inside the EML, holes and electrons combine to form excitons, which cause electroluminescence. The key factors that determine the quality of OLED components are the transfer material, emission layer material, and electrode selection. It can be used with either an SPI or a USB interface, which can be selected by soldering two jumpers on the back. The design is entirely 5v-geared, with an onboard regulator and built-in raise converter. It's now easier than ever to connect your 3v or 5v microcontroller without the use of a stage shifter. If you want to use this OLED display module in your Arduino project, for that you will need few essential components like Jumper wires Breadboard Batteries or power supply
