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, and wide viewing angles over 160°—ensuring the display remains readable from virtually any angle .
This module features a PH2.0 connector on the back for easy cable management, keeping the front of your project clean. 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, Raspberry Pi, 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 132×64-bit SRAM display buffer (128×64 visible) and support for I2C interface
-
PH2.0 Connector (Back-Mounted): Convenient JST connector on the back 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
-
Wide Operating Temperature: Rated for -40°C to +70°C, suitable for industrial and outdoor applications
-
Onboard Pull-up Resistors: Built-in pull-ups on SDA and SCL lines – no external resistors required
