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.
