1.54-Inch OLED Display Module – Ultra-Low Power, High Reliability for Embedded & Portable Designs
Saef Technology Limited introduces a high-performance 1.54-inch OLED display module, designed for engineers and developers who demand clarity, efficiency, and ruggedness in compact form factors. Ideal for wearable tech, medical monitors, industrial handhelds, and IoT devices, this monochrome OLED panel combines exceptional optical performance with ultra-low power consumption—all in a small, easy-to-integrate package. Key Features & Technical Advantages:
128 × 64 pixel resolution with white OLED emission delivers sharp contrast and excellent readability in both dim and bright environments.
Rated for -40°C to +70°C, making it suitable for outdoor, automotive, and industrial applications where temperature stability is critical.
Consumes only 90µA (VDD) and 450µA (VCC) in full ON mode, with sleep mode current under 10µA—ideal for battery-operated and energy-sensitive devices.
Easy to interface with common microcontrollers (STM32, ESP32, Arduino, Raspberry Pi Pico) with minimal pin count and full command support.
Rated for up to 16,000 hours at optimized brightness settings. Tested under thermal shock, high/low temperature operation, and humidity per industry reliability standards.
We offer free semi-customization—add resistive or capacitive touch panels, modify connectors, adjust firmware, or tailor mechanical outlines to fit your product perfectly. Engineered for Real-World IntegrationSaef’s 1.54-inch OLED module is built with the system designer in mind:
Whether you’re developing a fitness tracker, a portable diagnostic tool, a smart sensor display, or a compact control panel—this module delivers reliable performance in a minimal footprint. Why Partner with Saef Technology?

| 1 | GND | Ground of Logic Circuit |
| 2 | VDD | Power Supply for Logic |
| 3 | SCK | Serial clock input. |
| 4 | SDA | Serial data input. |
| 5 | RST | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
6 | DC | This pin is Data/Command control pin. When the pin is pulled high and serial interface mode is selected, the data at SDIN will be interpreted as data. When it is pulled low, the data at SDIN will be transferred to the command register. |
| 7 | CS | Chip Select. Chip is selected when CS0 = “L”. |
