How it works

The sensor: the multi-touch panel

The touch panel is a transparent overlay that allows touch sensing. It is placed on top of the display monitor.

Here is how Stantum-type touch-panels are manufactured:

1. Two thin and transparent (glass or plastic) overlays are covered with conductive material
2. The material is patterned in rows on one side and columns on the other, transforming the layers into a matrix of conductive tracks.
3. The two layers are assembled superposed, the conductive sides facing each other and separated by a spacing material (transparent dots, air, etc.).

When one or multiple touches occur on such touch-panel, the top layer slightly bends, thus creating contact between the two layers right below the touches. The controller chip detects the electrical contacts and determines the exact location of the touches.

The multi-touch controller

The multi-touch controller chip is the core of the multi-touch technology. Powered by intelligent algorithms, it handles the scanning of the touch-panel, the touch detection and the cursor tracking.

The multi-touch module: sensor + controller

The multi-touch controller chip can be connected to the touch-panel either:

• Directly on the touch panel (chip on glass or COG)
• On the flex that is connected to the tracks (chip on flex or COF)
• On the board of the device, connected to the touch panel with a flex (chip on board or COB)

The resulting touch-module (touch-panel + controller) is integrated into the device, with the touch-panel on top of the display monitor.
