Product Description
Key Characteristics of a 128x64 COG Graphic LCD Display:
-
Resolution: 128 x 64 pixels, offering higher detail than the 128x32 LCD. This makes it suitable for displaying more complex images, text, and graphics.
-
Monochrome Display: Typically, a 128x64 COG graphic LCD is monochrome, meaning it displays a single color (often black on a white or gray background). This is suitable for applications where color is not necessary but the crisp and clear display of graphics or text is required.
-
COG Technology: The COG (Chip-on-Glass) approach integrates the driving IC (integrated circuit) directly onto the glass substrate, making the display more compact, cost-effective, and reliable. It reduces the space taken by external components, which is ideal for compact devices.
-
Communication Interface: These displays usually use serial interfaces like SPI (Serial Peripheral Interface) or I2C, though some might also support parallel communication.

This LCD monitor (LCD) features small size, low power consumption, high contrast (FSTN characteristics), and simplified integration (COG process). It is mainly targeted at electronic device scenarios where display requirements are streamlined and power consumption and installation space are sensitive. Its specific applications can be classified into four major categories: "Industrial Control, Consumer Electronics, Medical Equipment, and Smart Hardware".
The following is a detailed explanation:
Equipment Status Monitoring Screen
Used for small industrial controllers (such as PLC auxiliary screens, local screens of frequency converters), sensor data terminals (such as temperature and humidity sensors, pressure sensors, current and voltage monitors), it displays real-time data (such as "Temperature 25℃", "Pressure 0.8MPa"), and equipment operation status (such as "Running / Standby / Fault" icons or text).
Advantages: 128x64 graphic resolution can simultaneously display "value + simple icon" (such as using "√" to represent normal and "×" to represent fault), 3.3V low voltage compatible with the power supply system of industrial Internet of Things devices (mostly 3.3V/5V DC power supply).
IoT Terminal Display
Used for local displays of smart water meters, electricity meters, and gas meters, it displays cumulative usage, remaining quota, communication status (such as "Connected" "Disconnected"); it can also be used for small environmental monitoring nodes (such as machine room temperature and humidity screens, agricultural greenhouse sensor terminals), presenting environmental data intuitively.
Advantages: 26PIN FPC (flexible wiring) design suitable for the compact internal space of metering equipment (can be bent to fit into narrow installation areas), blue backlight can still clearly read the numbers in dim environments (such as underground pipe wells, machine room corners).
Small appliance control panel
Used for "functionally streamlined" household appliances such as dehumidifiers, desktop humidifiers, and small ovens, it displays working modes (such as "dehumidification / ventilation"), set parameters (such as "humidity target 50%"), and running duration.
Advantages: The 128x64 resolution can meet the display requirements of "text + simple graphics" (such as using water droplet icons to represent dehumidification), the blue backlight conforms to the modern minimalist design style of household appliances, and the COG technology (the chip is bonded to the glass) reduces external components and reduces the size of the appliance motherboard.
Medical auxiliary terminal
A local display for small infusion alarms and bed callers, showing the remaining infusion time, call status (such as "Call from Bed 3"), and device battery level.
Advantages: The flexible connection of 26-pin FPC can adapt to the irregular shapes of medical equipment casings, and the high reliability of COG technology (reducing contact failures) meets the stability requirements of medical equipment.
Smart wearables and portable terminals
For small smart keychains (displaying time, Bluetooth connection status), mini voice recorders (showing recording duration, remaining storage space), outdoor compasses (displaying direction, altitude), etc.
Advantages: Small size (2.7 inches) and lightweight design are suitable for wearable devices. The blue backlight can still clearly display in outdoor low-light environments (such as cloudy days, dusk), and the low power consumption can extend the device's battery life (such as keychain-type devices can go months without battery replacement).
