1.54-inch OLED Display Module – Ultra-Low Power, Wide Temperature, SPI Interface, Customizable
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:
- Crisp Monochrome OLED Display
128 × 64 pixel resolution with white OLED emission delivers sharp contrast and excellent readability in both dim and bright environments.
- Wide Operating Temperature Range
Rated for -40°C to +70°C, making it suitable for outdoor, automotive, and industrial applications where temperature stability is critical.
- Extremely Low Power Draw
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.
- Simple 4-Wire SPI Interface
Easy to interface with common microcontrollers (STM32, ESP32, Arduino, Raspberry Pi Pico) with minimal pin count and full command support.
- High Reliability & Long Lifespan
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.
- Custom Touch & Design Flexibility
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 Integration
Saef’s 1.54-inch OLED module is built with the system designer in mind:
-
Robust power sequencing circuitry protects the OLED panel and extends operational life

Pin Interface Definition
| PIN | SYMBOL | Descriptions |
| 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”. |
