A Chip-On-Glass Display Modules (abbreviation COG) is a display with an integrated display driver. This driver chip is located directly on the glass of the display, therefore "Chip-On-Glass".

Chip-on-glass technology is a modern technology for the cost-effective production of high-quality displays. All EA DOG displays are manufactured using chip-on-glass technology. These displays are very flat and can be combined with a wide variety of lighting (including RGB). Thanks to pins, our COG displays are easy to assemble and versatile (also as a single piece). The test board with USB interface enables simple testing of these COG displays. The DOG series is available for a long time and can be delivered from stock, distributed worldwide in industrial and medical products.
