Smartphone Demand is Growing
Worldwide handset sales to end users totaled 1.75B units in 2012
Smartphones account for over 50% of all new U.S. mobile subscribersSmartphone sales grew by 38% worldwide in 2012
Smartphones unlock access to an ecosystem of Apps
Over 675k Apps available with over 25B downloads in Google Play
Over 800k Apps available with over 40B downloads in iOS App Store
Mobile traffic represents 13% of all internet traffic….and growing
“Gartner predicts that sales of worldwide smartphone sales to end users will be close to 1 billion units in 2013, and overall mobile phone sales to end users are estimated to reach 1.9B units.” – Research firm Gartner
“Mobile devices are changing from being an adjunct for occasional remote usage to being the primary way that a broad swath of workers handle information.” – Rhomobile
TrueTouch-powered devices enable faster, more accurate mobile phone designs that perform under arduous conditions

Terms You May Hear from Engineers
Accuracy (mm)Distance along a straight line between the actual touch object position and the reported object position
Linearity (mm)Deviation of the position data from the best-fit straight line
Refresh Rate (Hz)Average time between two consecutive frames of touchscreen data available in a data buffer
Jitter (mm)Maximum deviation of the reported position when a stationary touch object is on the touchscreen
Response Time (ms)Time from a touch down event while the touchscreen controller is in active or lower power mode to the touchscreen controller generating an interrupt signal
Signal to Noise Ratio (SNR)Measurement that compares the level of a desired signal to the level of background noise

TrueTouch Terms
TrueTouch Host Emulator (TTHE)Design, configure, debug, and tune all-in-one development tool for simulating
touchscreen applications
Install software directly to your PC
Integrate tuning/testing wirelessly using TTHE Mobile Tuner
Include Android and Windows OS drivers
Manufacturing Test Kit (MTK)Test prototype performance with mobile device before production
Validate final panel design prior to mass production
Charger ArmorConfigurable solution for touchscreen interference from cell phone chargers
Charger noise is caused by poor charger electronics design
Signal interference can register false touches, reduce input accuracy and cause touchscreens
to stop functioning completely
TrueTouch Charger Armor

Design Problems Engineers Face
1. Accurate touch detection on panel when liquid is present; IP-67 CompliantFalse touches on capacitive touchscreen surfaces when liquid is present
Inaccurate registration of touch location on wet panel surfaces
Touchscreen must be reset before recalibration (baseline error)
2. Charger noise significantly degrades accuracy and linearity Noise injected from mobile phone chargers can render it unusable
Charger noise creates false touches, positional jitter and discontinuous touches
Low cost aftermarket chargers have poor noise shielding and are dominating worldwide charger market
3. Touch data processing needs to be done on the host core for optimum performanceLow performance CPU, less Flash and RAM limits data processing
Host processor requires sufficient power to support touch registration and advanced features simultaneously
Resulting in slower response time and limits opportunity for feature enhancement
TrueTouch solves these problemsWaterproofing technology delivers water-rejection, wet-finger tracking, and baseline recalibration; IP-67 Compliant
Charger Armor increases noise immunity up to 10vpp
A 32-bit ARM M0 CPU with 64k Flash and 8k RAM delivers the highest performance
Only Gen4 delivers best-in-class noise immunity and our patent-pending waterproofing capability
