Assembly of LCD Modules

With ever-increasing demands for reduction in size and weight of flat panel display devices such as liquid crystal display (LCD), electrical and physical interconnections between electronic components and a substrate are made using surface mounting technologies, including Chip-on-Glass (COG) and Chip-on-Film (COF). For Chip-on-Film, an LCD driver chip is mounted on a flexible circuit which is attached to the contact edge of the LCD glass. In Chip-on-Glass; an LCD driver chip is mounted directly on the surface of the display glass, resulting in a thinner and lighter LCD.

More and more LCD makers select COG as one of the most cost-effective technologies for small and medium size displays. COG interconnections allow for finer pitch to handle smaller and more numerous pixels, and the integration of more functionality on driver IC chips. For mobile devices in particular, the trend is to incorporate row and column drivers for multiple displays into a single chip. Another factor pushing to finer pitch is silicon die size reduction in order to reduce the cost of the display.

This application note will describe how the OmniCure® S2000, along with a High Power Fiber Light Line, can be used to improve the assembly process of small LCD modules such as those on mobile handsets.
