Design capacitive touch screen displays using single-layer multi-touch controller from IDT

Integrated Device Technology has unveiled what is calls the industry's first touch screen controller IC optimized for IDT's proprietary single-layer multi-touch projected capacitive touch screen technology. This single-layer touch screen technology does not need cross-over isolation points that other solutions require but still maintain full multi-touch feature. Suggested applications include mobile handsets, personal navigation devices, and handheld gaming platforms with screen sizes up to five inches.

The other key features of IDT LDS7000 and LDS7001 include:

Offer native support for a 10-bit resolution (1024 x 1024) with the ability to scale the touch values of the X and Y axes, offering the flexibility to apply this solution to different resolution LCD and AMOLED panels
Features up to 30 and 35 sensor channels, respectively.
Operate at a speedy 8ms data rate for quick response to touch inputs.
IDT LDS7000 family's proprietary algorithms eliminate undesired multi touch ghosting, providing accurate individual X and Y coordinates in dual touch mode.
The devices' analog front-end design provides a high level of noise rejection performance eliminating the need for a separate touch screen shield layer for most applications
.
"The new LDS7000 family of touch controllers enables our customers to take full advantage of IDT's true single-layer touch screen technology," said Alvin Wong, general manager of the Advanced User Interface group at IDT. "Our innovative design and multi-touch capabilities allow touch screen manufacturers to simplify their manufacturing processes, yet maintain the critical feature set that is required for today's most advanced consumer devices. IDT continues to extend its presence in breakthrough capacitive touch technologies and designs that improve the user experience, so our customers can deliver winning products to the market."

"The market for multi-touch capable controllers continues to expand based on increasing adoption rates across the globe of smartphones, and since 2010, an exploding market for media tablet PCs," said Randy Lawson, Principal Analyst, Display Electronics at iSuppli Corporation. "As screen resolutions and application processor data rates continue to climb in these applications, the ability to discern and reject injected noise at the controller has become a more compelling feature for device manufacturers when selecting their touch screen controller IC provider."
