Advantages of COG LCD Display
Compact Design
The display driver IC is mounted directly onto the glass substrate, eliminating the need for a separate PCB, which reduces the overall module thickness and footprint.
Fewer Components
Since there's no extra PCB or long connector between the IC and the glass, fewer parts are involved, resulting in better durability and easier assembly.
Low Power Consumption
COG LCDs consume very little power, making them ideal for handheld devices, meters, and battery-operated instruments.
High Integration
Many COG modules come with built-in controller/driver ICs, support for standard interfaces like SPI/I2C/parallel, and sometimes include flash memory.
High Contrast & Sharpness
Excellent optical performance due to short signal paths and direct drive. FSTN or STN options are available to optimize contrast and viewing angles.
Backlight Optional
Optional LED backlight can be added as needed. Reflective or transflective polarizers are also available for low-power applications without a backlight.
Long Life & High Reliability
The structure is simpler, with fewer soldering joints and connections, resulting in stable long-term performance and fewer failure points.
Cost-Effective for Medium-Volume Customization
Especially suitable for custom segment or graphic displays with moderate MOQ. No need for expensive driver boards or additional hardware.
Considerations When Buying COG LCD Display
Display Type & Resolution
Character, Graphic, or Segment: Choose based on your application (e.g. 128x64 graphic, or 16x2 character). FSTN / STN / VA Options: FSTN = better contrast and viewing angles. STN = economical and reliable. VA = high-contrast, black-background style.
Glass Size and Viewing Area
Review the outline dimensions, active area, and thickness. Ensure it fits within your device’s housing and bezel window.
Driver IC & Interface Compatibility
Common ICs: ST7565, UC1609, SSD1309, etc. Confirm interface type: SPI, I2C, or Parallel. Make sure your MCU supports the display's protocol and timing.
Voltage & Operating Conditions
Operating Voltage (VDD): Usually 3.0V or 3.3V. LCD Driving Voltage (Vop): Confirm based on contrast performance. Temperature Range: Choose between commercial (0~50°C), industrial (-20~70°C), or extended (-30~80°C).
Backlight & Polarizer Selection
Polarizer Types: Reflective (no backlight), Transflective (sunlight-readable), Transmissive (requires backlight). Backlight Options: White, Blue, Green, RGB; check brightness and power rating.
FPC Layout & Connector Requirements
Check: FPC length, pin pitch (e.g. 0.5mm, 1.0mm). Connection method: ZIF, hot bar soldering, or custom connector. Pad alignment for your mainboard design.
Viewing Angle & Display Direction
Typically defined in clock angles (e.g. 6 o’clock, 12 o’clock). Match to product orientation for optimal readability.
Touch Panel Integration (Optional)
Some COG modules support integration with resistive or capacitive touch panels. Confirm signal routing and bonding method if needed.
Customization Options
Many COG LCDs can be customized for: Glass outline, Icon/logo printing, Custom backlight or pin layout, Wide viewing or extended temperature.
Certifications & Reliability Standards
Verify with supplier: RoHS / REACH compliance, ISO9001 certified factory, Display lifetime, contrast ratio, response time, aging tests.
FAQ
COG (Chip-On-Glass) integrates the driver IC directly onto the glass, allowing for a thinner profile, smaller footprint, and better shock resistance compared to COB (Chip-On-Board), which uses a separate PCB.
We provide a recommended Vop, bias, and duty ratio based on your display’s duty cycle and structure. Custom adjustment is possible upon request.
Absolutely. We offer custom LED backlight integration with selectable color, brightness, structure (edge/array), and mechanical height.
We support SPI, I2C, 6800/8080 parallel, and custom interfaces via FPC design with specific PIN definitions.
Our process supports dot gaps as low as 0.015mm, allowing for high-density custom dot matrix layouts.
Yes. We can tailor glass outline, pixel resolution, viewing direction, and interface (SPI/I2C/Parallel) based on your system requirements.
