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.
