Chi Mei has many different Touch panels, from 12.1″using a photo sensor, to a 23.6″Out-Cell touch solution. The optical sensor can detect up to 10 points on the screen simultaneously. The Out-cell solution uses two points for multi-touch. The In-cell touch solution on the 10.1″screen caters for more touch points. The out-cell solution is ideal for monitors already on the market, whereas the In-cell technology will be integrated into the new monitors.
Multitouch screen from CTO demonstrated at Display Taipei 2009, using the optical type of sensor where an unlimited number of touch points can control your PC desktop environment. With Windows 7 multitouch software imminent, the multitouch screens will do very well and should be featuring in alot of future notebooks and PC screens.
The notebook screens can have only 2 or 3 points on the touch screens, which can be adjusted to accept more points should developers need it.
