Shenzhen Jinghua Displays Co. Ltd has started marketing chip-on-glass (COG) LCD panels.

COG is a high-tech mounting method that uses gold bump or flip chip ICs and is implemented in most compact applications. First introduced by Epson, COG IC technology reduces a mounting area and is suitable for handling high-speed or high-frequency signals. It is used to produce advanced LCD modules for high-end electronic products such as mobile phones and PDAs.

In flip-chip mounting, the IC is not packaged but is mounted directly onto the PCB as a bare chip. Because there is no package, the mounted footprint of the IC can be minimized, along with the required size of the PCB.
