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.
