Description
128×64 Display Product Introduction
This high-performance 128×64 Display is a dot-matrix monochrome LCD module featuring FSTN Transflective technology, ensuring excellent contrast and clarity in both indoor and sunlight conditions. Integrated with the ST7567 driver IC and supporting a 3.3V power supply, it is the perfect visual solution for compact embedded systems requiring low power consumption and high reliability.
Key Features
- Superior Visual Clarity: The 128×64 Display resolution with a precise 0.37×0.37mm dot pitch delivers crisp text and detailed graphics.
- Wide Temperature Range: Engineered for industrial use, it operates stably between -20°C and 70°C, making it suitable for harsh environments.
- Streamlined Interface: Utilizing a serial interface (SCLK/SDA) to minimize MCU I/O usage and simplify PCB routing.
- Ultra-Thin COG Design: The Chip-on-Glass (COG) construction combined with a flexible FPC connection reduces the overall footprint for handheld devices.
- Low Power Backlight: Equipped with a white LED backlight that maintains high brightness while drawing only 45mA of current.
Application Scenarios
- Industrial Instrumentation: Pressure calibrators, power monitoring meters, and thermostat control panels.
- Smart Home Systems: Security alarm interfaces and smart control hubs.
- Portable Devices: Infrared thermometers, handheld POS terminals, and diagnostic testers.
- Medical Equipment: Pulse oximeter displays and control interfaces for portable nebulizers.
Selection Guide for 128×64 Display
When selecting the right model for your project, consider these core specifications:
- Display Mode: Choose FSTN for high contrast or STN for budget-sensitive projects.
- Operating Voltage: This model is optimized for 3.3V systems; check your MCU compatibility.
- Dimensions: Verify the 65.26 x 43.96 mm physical size and viewing area against your enclosure design.
- Connection: This unit uses a 10-pin FPC with a 1.0mm pitch.

Asked Questions
Q1: How to select the right 128×64 Display for your project?
Answer: When choosing a 128×64 Display, first evaluate the physical dimensions and viewing area to ensure it fits your device housing. Next, consider the communication interface, such as SPI or Parallel. For lighting conditions, if your product is used outdoors, a Transflective 128×64 Display is highly recommended because it remains clearly visible under both direct sunlight and internal backlight. Finally, always verify the logic voltage to prevent electrical mismatch that could damage the driver IC.
Q2: Is this 128×64 Display compatible with 5V systems?
Answer: The standard operating voltage for this specific 128×64 Display is 3.3V. If your main controller, such as a traditional 51 MCU or certain Arduino boards, operates at 5V, it is best to use a level shifter or series current-limiting resistors on the signal lines (CS, RES, SCLK, SDA). This precaution ensures the long-term stability and safety of the 128×64 Display.
Q3: Why is the backlight working but no content is shown on the 128×64 Display?
Answer: This common issue is usually caused by one of three factors. First, bias voltage settings: the ST7567 driver requires a specific V0 bias voltage, so please check if the external capacitors on the V0 pins are connected correctly according to the datasheet. Second, initialization code: ensure the contrast or electronic volume commands in your software are not set to an extreme value. Third, connection reliability: inspect the 10-pin FPC connector to ensure it is properly seated and free from oxidation.
