Programmable chip enables flexible touchscreen

LG Electronics has implemented Cypress's CapSense capacitive touch sensing solution for the user interface in the new LG LA-N131 consumer air cleaner.

LG Electronics has implemented Cypress's CapSense capacitive touch sensing solution for the user interface in the new LG LA-N131 consumer air cleaner.

The CapSense solution requires only one chip to enable the touch panel for the LA-N131, whereas multiple components would have been required with competing technology.

The LG LA-N131 air cleaner is the newest product in LG's air cleaner portfolio utilising the world's first platinum catalytic system.

Its luxury and sophisticated design match any interior, and its compact design allows it to fit in rooms of all size.

The LA-N131's touch screen interface and wide LED display offer easy operation by any user.

It also features a washable HEPA (high efficiency particulate air) filter, eliminating the need to exchange air filters.

Cypress's Programmable System-on-Chip (PSoC) mixed-signal array with CapSense technology implements the touch screen interface that is one of the remarkable features in the LA-N131.

A single chip (the CY8C21534) enables this reliable CapSense-based interface with smarter appearance and more robust operation than mechanical switches or buttons.

The Flash-based PSoC architecture enabled LG to make changes in the design late in the design cycle.

The result was fast time to market as well as BOM and cost reduction.

This is the second application for which LG has selected Cypress CapSense technology.

LG Electronics Mobile Communications Company previously selected the CapSense solution for the new LG-KV5900 Cyon mobile phones.

"Cypress's CapSense technology offers attractive styling, durability, fast design cycles and lower component costs", said a spokesperson for LG Electronics.

"These factors, along with superior local design support, contributed to the successful launch of the LA-N131 air cleaner".

"The LA-N131 is an excellent showcase for the CapSense solution", said George Saul, Vice President of Cypress's PSoC Business Unit.

"It demonstrates the aesthetic and design benefits that CapSense delivers to home appliances, a large market for capacitive sensing implementations".

"We are also pleased that LG has validated the technology by choosing a second product in which to use our CapSense solution".
