NDTG128128001 | 128×128 COG LCD Module 2.1 Inch FSTN Transflective Display UC1617 Controller White LED Backlight 8-bit Parallel for Arduino
The NDTG128128001 2.1″ 128×128 COG LCD Module is a compact and reliable display solution designed for embedded and handheld applications. Built with chip-on-glass (COG) technology, it offers a slim profile (only 4.3mm thickness) while maintaining excellent durability and performance.
This 128×128 transflective FSTN+ positive LCD delivers clear, high-contrast visuals under both indoor and outdoor lighting conditions. Powered by the UC1617 controller (or equivalent), it supports 6800/8080 8-bit parallel interfaces for smooth data transfer and easy integration.
With a white LED backlight, wide operating temperature range (-20°C to 70°C), and flexible voltage options (3V/5V), this module is well-suited for industrial control devices, portable instruments, and consumer electronics. Its 22-pin connection ensures stable integration with Arduino, Raspberry Pi, and similar development boards, making it an ideal choice for developers who need a reliable COG LCD display.
