Touch controller support gloved fingers, thin stylus and also feature prox. Sensor

Cypress Semiconductor has launched new touchscreen controller chips TrueTouch Gen4 with the below new features: 1. Supporting gloved fingers: The Gen4 TMA467 controller tracks up to 10 fingers in thin gloves and two fingers with thicker gloves, such as those used by skiers. It automatically switches between glove and finger tracking without any intervention. A video demonstration of this capability is available at www.cypress.com/touch. 2. Passive Stylus support: The Gen4 TMA468 controller supports passive styli with tips as small as 2 mm, enabling touchscreens to capture characters as small as 7 mm. This capability is important for writing in languages that require enhanced character recognition for reliable text input, such as Chinese and Japanese. The controller delivers a high degree of accuracy and linearity, along with the fast refresh rates required for handwriting and signature capture, claims Cypress. 3. Proximity Sensor: Proximity detection that senses an object approaching the touchscreen and powers down the display before contact to avoid accidental touches. The Gen4 TMA466 controller’s proximity sensing detects objects such as a user’s face up to 25 mm away from the screen and disables detection when a user is on a call in case their face touches the screen. It also instructs the host to turn off the display to save power and prolong ...
