Description
Product Overview
The 1.3-inch White OLED Display Module is a high-contrast, energy-efficient graphic display designed for embedded systems, IoT devices, and portable electronics . Powered by the SH1106 driver IC and featuring a crisp 128×64 pixel resolution, this larger-format display delivers bright white text, detailed graphics, and custom icons on a true black background.
OLED (Organic Light Emitting Diode) technology requires no backlight, as each pixel emits its own light. This self-emissive design provides true blacks (inactive pixels are completely off), an exceptional contrast ratio of 2000:1, and wide viewing angles over 160°—ensuring the display remains readable from virtually any angle .
The module features a convenient PH2.0 connector on the front, making it easy to connect using standard 4-pin JST cables. It uses the I2C (IIC) interface, requiring only two data lines (SDA and SCL) to connect to your microcontroller. This preserves valuable I/O pins for other sensors and peripherals .
With support for both 3.3V and 5V logic, it is directly compatible with Arduino, ESP32, ESP8266, STM32, and most other development boards – no level shifters required . The larger 1.3-inch active area offers noticeably more space for UI elements, dashboards, and menus than the 0.96-inch version while maintaining the same simple 4-wire I2C hookup .
Key Features
-
Larger 1.3-Inch Active Area: 29.42 × 14.7mm display area offers significantly more screen real estate than 0.96″ displays while maintaining 128×64 resolution
-
White Monochrome OLED: Clean white pixels on true black background provide excellent contrast and professional appearance
-
SH1106 Driver IC: Industry-standard controller with built-in 128×64-bit SRAM display buffer and support for I2C interface
-
PH2.0 Connector (Front-Mounted): Convenient JST connector on the front for easy plug-and-play installation using standard 4-pin cables
-
I2C Interface: 4-pin connection (VCC, GND, SCL, SDA) with default address 0x3C – requires only 2 data lines
-
Wide Voltage Compatibility: Operates on DC 3.3V – 5V, compatible with both 5V (Arduino) and 3.3V (ESP32/ESP8266) systems
-
Ultra-Low Power Consumption: ~20mA typical operating current (all pixels on), with no power consumed by unlit pixels – ideal for battery-powered projects
