0.96 Inch SPI OLED LCD Module 6pin (with GND VCC) Blue SSD1306 Chip

0.96 Inch SPI OLED LCD Module

The 0.96-inch Blue OLED Display Module is a versatile and efficient display solution that can easily interface with any microcontroller using SPI/I2C protocols. With a 128×64 resolution, it provides clear and detailed visuals. The module package includes the display board, the OLED display unit itself, and a pre-soldered 6-pin male header for convenient and hassle-free connectivity.

OLED (Organic Light-Emitting Diode) technology is a self-emitting display technology that uses a thin, multi-layered organic film placed between an anode and cathode. Unlike LCD displays, OLEDs do not require a backlight, leading to thinner designs, lower power consumption, and improved energy efficiency. OLED technology has great potential for a wide range of applications and is considered the leading technology for next-generation flat-panel displays.

The OLED structure consists of organic materials between the cathode and anode, with the anode typically made of transparent, electrically conductive Indium Tin Oxide (ITO). These organic materials form a multi-layered thin film, including the Hole Transport Layer (HTL), Emission Layer (EML), and Electron Transport Layer (ETL). When a voltage is applied, electrons and holes are injected into the EML from the cathode and anode, respectively, where they combine to form excitons. This process results in electro-luminescence, generating light emission.

The choice of materials for the transport and emission layers, as well as the selection of electrodes, plays a critical role in determining the performance and quality of OLED displays. With its numerous advantages, OLED technology provides superior display quality, energy efficiency, and design flexibility, making it an ideal choice for a variety of display applications.

Setting up SPI/I2C Connection with GMS096A OLED Module

Being a new entry to the market, only limited resources are available on this small piece of miracle (GMS096A). I2C/SPI configuration always demands helpful resources as in any case. For the SPI setup, the module comes in 4 wire SPI configuration by default and to make it work with the arduinos you can use these libraries from Adafruit.

For the I2C setup it demands a little bit of work on the module. Actually it was one of our customers who shared these simple configuration steps with us, start with resoldering the resistor from position R3 to R1 and then short the R8 resistor with some solder tin (0 Ohm resistor). The R6 and R7 pullup resistors are already soldered, nothing to do there. Once done, the module is ready for I2C communication! The CS Pin is not necessarily needed, so just connect it to GND. The DC Pin selects the address. For standard address wire it to GND. The RES-pin needs a low pulse at startup and high voltage during operation (as in SPI mode), a 100nF capacitor to GND and a 10k res to VCC would be ideal!
