LG Electronics has selected Cypress Semiconductor Corp.'s TrueTouch touchscreen solution to implement a capacitive touchscreen interface in its new KS360 mobile handset. With the programmable TrueTouch solution, based on the PSoC architecture, LG designers had a wide variety of touchscreen and LCD materials, and vendors to choose from to create the design. The projected capacitive touchscreen provides a next-generation user interface for optimal management of applications.

The KS360 phone has a sliding QWERTY keypad and specialized messaging application features. To make messaging easier, the screen automatically rotates 90 using accelerometer technology once the full length keypad has been opened. The KS360 also comes with a 2Mpixel camera and MicroSD card slot.

Cypress's TrueTouch touchscreen solution enables OEMs to use a full portfolio of Cypress-developed single-touch and multitouch gestures such as tapping an application to open, panning through photo albums, scrolling down an e-mail, and rotating and pinching pictures. Cypress also provides multitouch capability for up to 10 fingers for more complex applications including virtual keyboard and gaming. This capability provides touchscreen designers with the freedom to create new interfaces for mobile handsets, portable media players, GPS systems and other products.

"The compact size and sliding capability of the KS360 required a flexible touchscreen solution," said Ji Hoon Jeong, project leader at LG. "Cypress Semiconductor's TrueTouch touchscreen solution allowed us to work with the touchscreen and LCD vendors of our choice to get the exact look and feel we wanted."

"With increasing demand for a wide variety of touchscreens, we believe the flexibility of the Cypress TrueTouch solution is ideally positioned to enable the next generation of touchscreen products," said Dhwani Vyas, VP of PSoC CapSense and touchscreen business unit at Cypress.
