IDT Develops and Demonstrates Industry’s First Touch-Over-AUX Embedded DisplayPort 1.3 (eDP)-Based Timing Controller (TCON)
Integrated Device Technology developed and successfully demonstrated the industry’s first touch-over-AUX Embedded DisplayPort 1.3 (eDP™)-based timing controller (TCON) with integrated touch screen controller. The new TCON processes and transmits touch sensor data over the eDP auxiliary channel, eliminating a supplemental touch screen controller and USB interface to save space and lower costs in notebook, Ultrabook, and tablet applications.
IDT’s new eDP 1.3 TCON features an integrated touch controller designed to transmit touch data over the existing DisplayPort auxiliary channel, allowing system makers to eliminate a costly USB interface and reduce the number of wires that must pass through a display’s hinge. Integration of a touch sensor controller alongside the eDP-based LCD TCON allows display panel manufacturers to reduce component count and simplify overall system design, resulting in lower cost and smaller physical dimensions. The IDT device includes an embedded MicroController Unit (MCU) and Serial Peripheral Interface (SPI) for communication with the touch sensor.
IDT’s new eDP 1.3 TCON is the result of a development following a prototype demonstration announced in January at the 2011 Consumer Electronics Show (CES). The successful demonstration of a single-chip solution is a testament to IDT’s system-level engineering approach and strong mixed signal design capabilities.
