ChipMOS' Chip On Film (COF) package provides both mechanical and electrical support to the display driver semiconductors between the display panel and the driving module for the application in flat panel displays. Furthermore, the driving module can be manufactured by using COF technology with finer inner lead pitch and more lead counts. Turn-key services for COF packages, from gold bumping to final test, are available in current ChipMOS assembly lines.
Applications
Main applications are for driving display panel in LCD/OLED TV/monitor, NB, cellular phone, fingerpint sensor… etc.
Features
- Fine pitch COF
- COF with module
