COG (Chip-On-Glass) displays are monochromatic, passive- or active-matrix LCD displays that can display information as text or in a dot matrix pattern. Unlike typical LCD displays, COG displays do not have a built-in PCB board. Instead, the IC is directly mounted on the glass of the display. COG displays are perfect for less demanding applications since they require less power than VFDs, are smaller in size and are typically less expensive than other display technologies.
