LCDs are often supplied as LCD modules which have built-in driver circuitry that simplifies installation and improves reliability. However, the addition of packaged driver circuitry in Instrument Clusters LCD modules also results in a number of disadvantages because it:

Increases the thickness of the display

Raises the costs

Creates greater vulnerability for failures of the modules

All of these drawbacks are important considerations when it comes to displays for industrial, automotive and portable equipment. That’s why designers in these areas should strongly consider using Chip-on-Glass (COG) LCD modules. Chip-on-Glass (COG) LCD modules offer a very thin profile, enhanced reliability, and a reasonable price.

In comparison, COG modules have the LCD driver mounted directly on an overlapping edge of one of the glass plates that make up the LCD. The resulting module is an integrated display, less than 3 mm thick, with all connections from the LCD driver to the LCD completely isolated from the environment. With COG modules, each connection requires only one bond, which ensures optimal reliability of the module.

As the pioneers of chip-on-glass LCD technology, we have worked closely with leading manufacturers for years to lower costs, simplify PCB layouts, and improve the upgradeability, flexibility and reliability of their LCD displays using COG designs. Bringing accurate, reliable solutions for on-board displays replacement, which also builds on our proven capacity of delivering high quality COG LCD product units to the automotive aftermarket.
