Neonode Intros Low-Power Optical Touch Controller
Neonode today announced the NN1001, a single-chip optical touch controller for smartphones and tablets that it developed in collaboration with Texas Instruments. Neonode says that the NN1001 scans at 1000Hz with latency as low as 1 millisecond. The controller uses less than 1mW at 100Hz, which Neonode says puts the NN1001 in a class above most current touch solutions. The controller interacts with multi-touch sources such as fingers, gloved fingers, passive pens, and can power screens up to 20 inches in size. The NN1001 uses Texas Instruments' analog signal chain and power management technologies, which reduces the controller's power requirements and offers a low signal-to-noise ratio. Last, the NN1001 uses Neonode's AlwaysON tech, which lets touch screens register input even with the device it is built into is in sleep mode. The controller is sampling to customers now, and will reach mass production by the second quarter of 2012.
