Custom & OEM 2.9-Inch COG Monochrome LCD With 240×128 FSTN Dual Interface Versatility COG Dot Matrix Display
1. Definition and Principle
COG Dot Matrix Display refers to a type of display technology that uses a Chip - on - Glass (COG) packaging method for dot - matrix - style displays. Here is a detailed introduction:
Principle
It consists of a matrix - arranged array of pixels, and each pixel can be independently controlled to display different colors or grayscale levels. By controlling the on - off state and brightness of these pixels, various images, text, and graphics can be presented.
2.Product Key Features and Advantages
(1) FSTN Clarity for Monochrome Display:
2.9-inch FSTN dot matrix LCD (240×128 resolution, ash-colored) delivers superior contrast and sharp text/graphic rendering, outperforming standard STN in readability—ideal for data-intensive applications (e.g., meters, gauges).
(2) Dual Interface Versatility:
Supports Parallel/Serial interfaces, enabling seamless integration with diverse microcontroller systems. Reduces design complexity for engineers building industrial, portable, or automotive devices.
(3) Rugged Environmental Endurance:
Operates in -20℃~+70℃ (stores in -30℃~+80℃), surviving extreme temperatures (outdoor, industrial, automotive use). 40,000-hour LED backlight ensures long-term reliability.
(4)Compact COG Design:
Ultra-slim module (71.50×48.20×5.30mm) with COG (Chip-On-Glass) packaging saves space, perfect for portable gadgets (e.g., handheld testers, wearable monitors) and space-constrained setups.
(5) Certified Quality & Compliance:
ISO 9001:2015/GB/T19001-2016 certification guarantees consistent manufacturing. REACH & RoHS compliance ensures global market access (eco-friendly materials).
