LCD Connection Types

Hi,

Am exploring different LCD connection types for a design the ones I have found are:
1. Elastomer / Zebra strip connector
2. Pin connection Thru hole / SMD

I wanted to know if there are any other connection types that are suited to mass production and quick assembly. Also I have seen that some IC drivers for LCD's offer a "Chip on Glass" option. In this case how does the chip connect with the actual LCD?

Thanks.
Looking for additional LCD resources? Check out our LCD blog for the latest developments in LCD technology.
 
Displays with a COG controller have the chip connected to the LCD by metallized tracks on the glass. The external connections are typically brought off thru a flex tail, which mates with a SMD type ZIF connector. The flex tail & ZIF method is well suited for production.

The Crystalfontz CFAX displays are a good example of that technology (although they aren't COG, the CFAX have the chip on the flex tail, but the effect is the same).

Thanks for that cosmicvoid, much appreciated.

Could a COG solution also be used in conjunction with a zebra strip. Just trying to explore all the options.

Thanks
