This is the 1.3-inch blue OLED display module. Using I2C protocols, the display module can communicate with any microcontroller. It has 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. This 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 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 combine to form a multi-layered thin film that includes the Hole Transporting Layer (HTL), Emission Layer (EML), and Electron Transporting 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.
If you want to use this 1.3 inch OLED display module in your Arduino project, that you will need a few essential components like
The Organic Light-Emitting Diodes (OLEDs) are a type of display device. These Displays are self-lighting displays made up of a thin, multi-layered organic film sandwiched between an anode and a cathode. OLED does not require a backlight, unlike LCD technology.
2. What is a I2C OLED display?
Because of the high contrast these displays are small (about 1" diagonal) but very readable. The controller chip turns on or off each of the 128x32 individual OLED pixels in this display. No backlight is required because the pixels itself generates light. It with I2C communication protocol and only requires just 4 wires to connect: VCC, GND, SCL, SDA
3. Is this display good for the eyes?
There is currently no evidence to suggest that stroboscopic high-frequency PWM dimming is not safe for the eyes.
4. Which is better OLED or LED?
These are lighter and thinner, consumes less energy, has by far the best viewing angle, and, while still more expensive, has come down significantly in price.
