A single chip widescreen capacitive touchscreen controller supports thinner displays and enhances users' experience, according to STMicroelectronics.
The S-Touch FingerTip controller has been designed to offer true multitouch capability with unlimited simultaneous touches. ST says it also enhances multitouch actions such as pinch to zoom and supports stylus operations.
The controller's analogue IP is said to provide high signal to noise ratio performance with high scan speed. According to ST, it also offers the industry's greatest number of channels, allowing higher touch resolution, while its low power consumption delivers longer battery life.
ST claims that its advanced noise cancellation makes this it the first device of its kind to support the latest on-cell lcd technology without requiring a ground shielding layer between the display and the touch sensor. This feature allows smartphones to have thinner touchscreen lcd modules with enhanced image quality.
The S-Touch Fingertip comes in a 3 x 3mm low profile chip size package, which ST says makes it the industry's smallest multitouch controller.
