Designing with TFT LCD Column Drivers
About the Presentor: Dick McCartney is responsible for strategic technology development for display applications. He has more than 20 years of experience, 8 display-related patents and a number of published papers. He received the H.W. Sweat Scientist and Engineer Award and other honors for his work on the Boeing 777 flat-panel designs. He has lectured on LCD displays extensively at university and industry forums both in the U.S. and Asia. Dick is an active member of the Society for Information Display (SID), where he has served as past-program chair and guest editor of the Journal of SID. McCartney is the general chair for the International SID 2005 Symposium.
This Seminar discusses the present useful information to successfully design with TFT-LCD column rivers. This includes a discussion of asymmetric gamma curves, static and dynamic Vcom characteristics, content specific gamma, output offset issues and proper routing and layout of differential pairs.
About the Instructor: Craig Zajac is a Staff Applications Engineer for the Displays Division located in Chandler, AZ. After graduating with a Masters in Material Science from Stanford University in 1996, he has held various positions within the semiconductor industry, including three as a column driver applications engineer with Vivid Semiconductor and National Semiconductor.

Reading Assignment:
- RSDS interface is used between the Timing Controller and Column Drivers. When designing with RSDS, it is important to design with EMI considerations in mind. To evaluate EMI for RSDS interfaces, use the basic equation:
EMI ~ N * I * A * f^2
N = number of loops
I = loop current
a = loop area
f = signal frequency
- To see more guidelines for designing the RSDS Bus Interface, read AN-1234, "RSDS Flat Panel Display Design Guidelines Part 1."
- To learn more about charge sharing, read AN-1235, "Using Smart Charge Sharing to Reduce Power and Boost Column Driver Performance."
