Touch-controller til store skærmstørrelser

Atmel lancerer første ultra-low power, single-chip touch controller til skærmstørrelser på op til 15.6” (in english).

Atmel has announced the maXTouch T Series, its next-generation family supporting touchscreens up to 23 inches for applications such as handsets, tablets, Ultrabooks, notebooks and all-in-one computers.

The first device in the family, the mXT2952T, is the world’s first ultra-low power single-chip device that supports Windows 8-certified touchscreens up to 15.6 inches and optimized to support touchscreen cover glass as thin as 0.4mm.

The new T Series delivers a revolutionary adaptive-sensing architecture featuring both mutual and self capacitance to optimize performance. The maXTouch T Series automatically selects the best sensing architecture, seamlessly switching to enable higher performance and lower power consumption.

Mutual capacitance enables true multitouch tracking while self capacitance offers benefits including idle power consumption, moisture immunity, glove tracking, and hover capability which detects a finger or an object not in contact with the screen.

The new maXTouch T Series enhances noise immunity with an industry-first capacitive touch dual analog and digital filtering architecture to deliver the best signal-to-noise (SNR) ratio and power consumption. The new features in the maXTouch T Series deliver improved responsiveness and a more intuitive user interface with additions such as hover that allow users to pre-select icons, letters, links and other images without physically touching the screen.

With the increasing popularity of active stylus on touchscreens, the maXTouch T Series natively supports Atmel’s maXStylus, a solution that requires no additional sensor layer to enable thinner stack-ups and lower overall bill of materials (BOM). The award-winning maXStylus offers a Window 8-compatible solution with better touch performance, lower power consumption and lower overall system cost than other capacitive active stylus solutions on the market today.

- Flawless touch performance, longer battery life and thinner screens for mobile devices are key features for today’s touchscreen designs, says Jon Kiachian, Vice President of Touch Marketing, Atmel Corporation.

- As a leader in touch technologies, the maXTouch T Series is Windows 8 compatible, Intel Ultrabook-ready, and supports both active stylus and sensor hub. We are a leader in this space, and excited to deliver the mXT2952T, the world’s first single-chip controller for Windows 8-certified touchscreens up to 15.6 inches.

To better support Ultrabook and notebook touch sensors, the mXT2952T has specific circuitry to take advantage of ITO (indium tin oxide) alternative sensor materials such as Atmel’s XSense flexible touch sensor. This allows system designers to build more innovative designs with faster operation, lower power, borderless and even flexible touchscreens.

The maXTouch T Series integrates Atmel’s proprietary maXFusion sensor hub management technology that enables designers to manage both the touch interface and all the sensor intelligence in a single chip. This technology enables lower bill of materials and higher performance.
