Interface standard for large screen LCD drivers

Samsung Electronics has announced the availability of a new interface standard for LCD driver ICs (LDIs). The CICC (Current Mode Interface Cascade COG/COF) standard uses a new technology for data transfer where the LDI is interfaced with the timing controller.
The standard operates on a lower current swing method (DI=200µA, DV=10mV) and adopts a serialized, cascade data transfer method that allows data to directly flow between adjacent LDIs. The technology also reduces EMI caused by the increased size in LCD monitors and TVs.



Samsung's interface standard uses improved technology for data transfer.

According to Samsung, the data bus line can be halved from 18 lines to 9 in a 6-bit LDI using the CICC standard, minimizing EMI and reducing power consumption by 20%. Samsung will apply the CICC standard to its devices for notebook PCs and large LCD TVs.
