Character LCD Display
COG (Chip-on-Glass) Character LCD Displays are ultra-slim, lightweight alphanumeric display modules designed for modern compact electronic devices. By bonding the driver IC directly onto the glass substrate, COG technology significantly reduces module thickness, minimizes component count, and enhances overall reliability compared with traditional COB (Chip-on-Board) solutions.
This product category includes popular character display formats such as 16×2 and 20×4, making them ideal for a wide range of applications including handheld devices, industrial instruments, medical equipment, smart appliances, and consumer electronics. The optimized outline dimensions and viewing areas help manufacturers build compact yet highly readable user interfaces.
These modules integrate advanced driver ICs such as ST7032i and SSD1803, offering stable performance, adjustable contrast, and efficient power management. Multiple communication interfaces—Parallel, SPI, and I²C (IIC)—ensure easy integration with various microcontrollers and embedded systems.
COG Character LCD Displays deliver crisp, high-contrast characters within well-defined active areas, ensuring excellent readability even in small display windows. Their low power consumption and slim design make them an excellent choice for portable and battery-powered products.
Key Features:
- Ultra-thin COG structure with IC mounted directly on the glass
- Character formats available: 16×2, 20×4
- Driver IC options: ST7032i, SSD1803
- Flexible interfaces: Parallel / SPI / I²C
