2014 Display Week Short Course 1 - Fundamentals of Projected-Capacitive Touch Te - 4070
Projected-capacitive (P-Cap) touch technology has become dominant in the CE/IT space (up to 27 in.) and is beginning to penetrate large-format applications. The other touch technologies (resistive at 9% of forecasted 2014 unit shipments and everything else at only 2%) have become much less relevant, so this short course focuses exclusively on p-cap. Topics include basic principles, sensor configurations, ITO and ITO-replacement materials, controllers, module construction and integration, the p-cap touch system, embedded p-cap (on-cell, hybrid in-cell/on-cell, and in-cell), multi-touch, OS support, middleware, large-format p-cap, active stylus, and future trends and directions.
