More options for infra-red touch screen systems

Edited by the Electronicstalk editorial team Jun 30, 2003

The latest additions to the CarrollTouch family of infra-red touch technology products include a USB controller board, low-profile screens, a ruggedised tempered glass filter and a controller chipset.

Elo TouchSystems has expanded its family of CarrollTouch infra-red touch technology products with the addition of a new USB controller board (4000U), three new, low-profile screens (10.4, 15.0 and 17.0in), a new ruggedised tempered glass filter for vandal-resistant protection, and a controller chipset that will provide volume users with greater design flexibility and cost saving solutions.

The new 4000U controller provides a USB interface to the host PC.

The new touchscreen sensors retain the low profile and slim form factor and continue to provide a high optical beam density of 22 points per inch.

When compared with an average industry density of 8 to 14 points per inch, Elo's low-profile infra-red sensors deliver a more precise performance.

In addition to the filter options of glass, acrylic and no filter, the new 6mm-thick tempered glass filter is ideal for applications that require protection in a rugged environment.

Other applications for Elo's CarrollTouch family include indoor/outdoor kiosks, ticketing machines, medical equipment, industrial automation and point of sale.

"CarrollTouch infra-red touch technology is now an even more affordable optical technology for the broadest range of indoor and outdoor applications", says Michael Bartelmess, Elo's European Director of Product Management.

"It is the perfect solution for those applications that require the highest clarity and durability in a broad range of environments, including direct sunlight".

According to Bartelmess, CarrollTouch's standard 10.4, 12.1, 15.0, 15.1 and 17.0in touchscreens remain the most popular sizes.

CarrollTouch lowprofile sensors provide a slim form factor that allows for easy integration in areas where space is at a premium.

The sensors are available with four filter options: no filter for maximum optical clarity, glass or acrylic filter for standard protection, and the new tempered glass filter for use in rugged environments.

Elo's CarrollTouch infra-red touch technology provides one of the highest light transmission rates in the market - up to 100%, based on filter option - so there is no compromise of image quality or colour purity.

The glass, acrylic, and tempered glass filters protect the display with minimal loss of image clarity.

"The new 4000U USB controller board has the same form factor and 4096 x 4096 resolution as the 4000S serial controller it complements", says Bartelmess.

"It increases the flexibility of connection to the host computer".

According to Bartelmess, Elo's new chipset provides support for either a USB or serial interface now combined in a single chip offering an economical solution to OEMs who seek design flexibility.
