0.96 Inch Blue I2C OLED LCD Module 4pin is an organic light-emitting diode (OLED or organic LED). Also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) is which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes and at least one of these electrodes is transparent.

- 0.96 Inch Blue I2C OLED LCD Module 4pin works without a backlight in a dark environment, OLED display is higher compared to that of LCD display. The Driver chip of this OLED is SSD1306, which is compatible with IIC or SPI communication. So this module can be controlled by SPI or I2C.
- There are 2 resistors at the back of the module and sick-screen to remind you how to set the communication mode, the default mode is 4-wires SPI mode.
- That is, except the VCC and GND, 4 wires would be needed when using 4 wires SPI mode.
- You can also set to the I2C mode in which mode 2 control wires is needed.
- There is also a simple switch – cap charge pump that turns 5v into a high voltage drive for the OLED’s, making this module the easiest ways to get an OLED into your project.
Product Applications
OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles and PDAs.
A major area of research is the development of white OLED devices for use in solid-state lighting applications.
