Abstract
By embedding optical sensors onto a TFT substrate in a display, a flat
panel can sense images projected by infrared (IR) light. Light pens which
can project Multi-
${\rm
T}$
-mark including out-mark and in-mark of IR images were
utilized to calculate the 3-axis information (
$x$
,
$y$
, and
$z$
) of the tip of the light-pen and achieve
accurate user identification accordingly. Therefore, a 3-dimensional virtual
touch display for 3-axis information with multi-user/multi-touch system can
be achieved.
