Integrated Device Technology has declared the development and demonstration of a first-of-its-kind timing controller (TCON) based on touch-over-AUX Embedded DisplayPort 1.3 (eDP) with built-in touch screen controller.
Integrated Device Technology Demonstrates Embedded DisplayPort-Based Timing Controller with Integrated Touch Sensor Controller
The innovative TCON processes and sends touch sensor data through the eDP auxiliary channel, resulting in the elimination of additional USB interface and touch screen controller, which in turn reduces prices and saves space in tablet, ultrabook and notebook applications.
The TCON’s built-in touch controller is created to send touch sensor data through the already available DisplayPort auxiliary channel, helping system manufacturers to avoid the use of an expensive USB interface and minimizes the count of wires that must traverse the hinge of a display.
The eDP-based LCD TCON’s touch sensor controller helps display panel producers to reduce the cost and size of devices by facilitating whole system design and minimizing the number of components. It features an entrenched serial peripheral interface and microcontroller unit to transmit with the touch sensor.
Integrated Device Technology’s new TCON is developed based on a prototype demonstrated at the Consumer Electronics Show in January 2011. The Director of Marketing for Integrated Device Technology’s Video and Display Operation, Jason Lu stated that the demonstration of its eDP TCON having touch-over-AUX is another testament of the company’s dominance in the eDP market. The new product is a win-win solution for system and LCD panel manufacturers, he said.
