<p><P>PROBLEM TO BE SOLVED: To provide an information input/output system for a liquid crystal display device that can use a laser beam pointer as an input system similar to a touch panel by displaying a position to be pointed on a liquid crystal display screen. <P>SOLUTION: The information input/output system for a large liquid crystal display device comprises a large liquid crystal display device 11, the laser beam pointer 21 opposed to a screen 12 of the liquid crystal display device 11 so as to point an arbitrary pointing position 13 of the liquid crystal display device 11, a detection means (detection plate) 25 for detecting the position to be pointed by the laser beam pointer 21, and a pointing display means for displaying the pointing position 13 of the liquid crystal display device 11 in response to the output signal from the detection means (detection plate) 25. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
