COG LCD Displays
Chip-on-Glass. Ultra-Compact. Design Flexibility.
Explore our range of COG LCD displays — liquid crystal modules built using Chip-on-Glass technology, where the driver/controller IC is mounted directly onto the LCD glass. This construction eliminates the need for a separate PCB in many designs, enabling ultra-thin, compact, and lightweight modules that are ideal for space-constrained and portable applications.
What Is a COG LCD Display?
A COG (Chip-on-Glass) LCD display is a liquid crystal module in which the driver/controller IC is bonded directly onto the LCD glass and connected via fine conductive traces, rather than being mounted on a separate PCB as in COB construction. This approach reduces overall thickness and weight, saves space, and allows greater flexibility in module shape and size. COG LCDs are widely used in compact character, graphic, and segment displays for portable and embedded devices.
