Capacitive Touchscreen Controller Enables Accurate Navigation

Patented capacitive sensing technology provides robust noise immunity for flawless operation in noisy RF and LCD environments.

TechInsight’s Teardown.com is reporting that Cypress Semiconductor’s TrueTouch controller is driving the touchscreen of the Qualcomm Toq smartwatch. The Qualcomm Toq teardown survey report identifies the Cypress TMA140 capacitive touchscreen controller in the ToqSW1 model, noting its fast, accurate touchscreen navigation. The ToqSW1 can be linked to a smartphone via Bluetooth, adding the ability to receive notifications and other content to standard watch functionality. Cypress’s TrueTouch technology boasts the industry’s best noise immunity, highest SNR, best waterproofing, fastest refresh rates, lowest power consumption, and world’s best accuracy and linearity. The robust noise immunity necessary for flawless operation in noisy RF and LCD environments is provided by the patented capacitive sensing technology of TrueTouch devices. Viable for innovative mechanical designs ranging from flat to curved surfaces of varying thickness, the TMA140 TrueTouch capacitive touchscreen controller also eliminates the need for turnkey modules and offers developers a choice of using touch sensors (glass or film) and LCDs from preferred partners.
