IDT’s Embedded DisplayPort TCON with Integrated Touch Controller Utilizes Auxiliary Channel to Eliminate USB Interface and Reduce System Cost in Notebooks, Ultrabooks, and Tablets
November 10, 2011

SAN JOSE, Calif., November 10, 2011 – Integrated Device Technology, Inc. (IDT®; NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced that it has 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.

        “Touch-over-AUX technology mitigates many of the cost adders associated with touch screen functionality in portable devices,” said Jason Lu, director of marketing for the Video and Display Operation at IDT. “Our demonstration of the industry’s first eDP TCON featuring touch-over-AUX is another example of IDT’s leadership in the eDP market. We are able to minimize LCD display panel costs and dimensions by integrating the touch controller into the TCON and also eliminate the touch data communication wire to the host by leveraging the existing DisplayPort AUX channel. This results in a win-win for LCD panel and system manufacturers.”

          IDT’s new device 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.
