What is COG?
http://www.highlystarelec.com COG stands for Chip on Glass. There are many different types of displays. COB (Chip on Board), COF (Chip on Flex), TAB (Tape automated bonding) and COG. This is an LCD technology where the controller chip used to drive the LCD is mounted directly onto the LCD glass. Mounting the controller directly onto the LCD glass allows the module to be built without the need for a PCB. The three main components of a chip on glass is the glass, the controller driver chip, and the cable. As a general rule the cost of a COG is less than that of a COB. Without being mounted to a circuit board, COG displays do not come equipped with mounting holes. Instead the COG display is mounted to the chassis if the manufacturer’s product uses double-sided tape.

By Flip Chip technology, a gold bumped IC chip is connected to the ITO of LCD panels with ACF as a m
