IDT Introduces Single-Layer Multi-Touch Controller

Where would be without Multi-Touch? It's hard to imagine, given that the vast majority of today's smartphones utilize some form of multi-touch, and many new all-in-one PCs, monitors and tablets do as well. Multi-touch has effectively revolutionized how we interact with displays, and Integrated Device Technology (IDT) has just created a major step forward in the multi-touch world. They're introducing the industry's first single-layer multi-touch capacitive touch screen controller, which doesn't require cross-over isolation points that other solutions require.

The catch is that even though it's a single-layer solution, it still maintains full multi-touch capability. The result is a lower-cost total solution that does not sacrifice features or performance. As you'd probably guess, the typical applications include mobile handsets, personal navigation devices, and handheld gaming platforms with screen sizes up to five inches. The IDT LDS7000 and LDS7001 are high-performance, multi-touch, full resolution touch screen controller ICs featuring up to 30 and 35 sensor channels, respectively. Both controllers operate at a speedy 8ms data rate for quick response to touch inputs to improve the user’s experience and enable advanced applications that require fast response times. The IDT LDS7000 family’s proprietary algorithms eliminate undesired multi touch ghosting, providing accurate individual X and Y coordinates in dual touch mode, a critical requirement for customers using host-interpreted custom gestures to differentiate their end product. The devices’ analog front-end design provides a high level of noise rejection performance that negates the need for a separate touch screen shield layer for most applications, lowering the overall solution cost even further.


That's a pretty deep explanation, but the gist of this is that our future multi-touch products could be slimmer, smaller and more more compact. The IDT LDS7000 and LDS7001 devices 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. In addition, the single-layer solution offers improved backlight transmittance, while the devices’ low power modes maximize battery life in portable electronics.

IDT is currently shipping samples to certain manufacturers, and hopefully it'll start popping up in products soon.

IDT Introduces Industry’s First Single-Layer Multi-Touch Capacitive Touch Screen Controller

PureTouch™ Controller IC Offers High-Performance, Multi-Touch Gesture Capability Optimized for IDT’s Single-Layer Touch Screen Technology

SAN JOSE, Calif.--(BUSINESS WIRE)--Integrated Device Technology, Inc. (IDT®) (NASDAQ:IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the industry’s first touch screen controller IC optimized for IDT’s proprietary single-layer multi-touch projected capacitive touch screen technology. This new touch screen technology and controller solution revolutionizes the market by offering a true single-layer solution, not requiring cross-over isolation points that other solutions require, yet still maintaining full multi-touch capability. The result is a lower-cost total solution that does not sacrifice features or performance. Typical applications include mobile handsets, personal navigation devices, and handheld gaming platforms with screen sizes up to five inches.

“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.”

The IDT LDS7000 and LDS7001 devices 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.

Very nice solution to this. I just hope no one sues them for having a pre-existing patent on multi-touch, as far as I know it has been somewhat coveted especially in the smart phone market. However; this is a hardware solution which may make a big difference. Not that a software solution cannot handle it, but I always go for direct hardware if I can get it personally.

Interesting.... a professor from waterloo was talking about how this is possible.... then he spent the other 45 mins of his lecture talking about inexpensive bendable lcd's that are shatter proof and how they can be used in the real world.

I understand that slimmer devices would be cooler.... but for now, the only problem i see is..... Bueller..... Bueller.....

The headphone jacks and what not.... they're still pretty thick. Heck... and i hate using the ipod touch as an example.... its only mm's thicker than the actual width of the headphone jack. I'm pretty sure apple can make it even more skinnier, but the i/o ports might cause some problems
