A LIGHT GUIDE PLATE FOR SYSTEM INPUTTING COORDINATE CONTACTLESSLY, A SYSTEM COMPRISING THE SAME AND A METHOD FOR INPUTTING COORDINATE CONTACTLESSLY USING THE SAME |
摘要 |
<p>Disclosed are a light guide plate for a non-contact type coordinate input system, a system including the same, and a non-contact type coordinate input method using the same. More particularly, the present invention relates to a light guide plate for a non-contact type coordinate input system, which eliminates inconvenience of a conventional contact-type coordinate input system inputting coordinates through direct contact, and which can reduce use of sensors and optical loss as much as possible. The present invention also relates to a system including the same, and a non-contact type coordinate input method using the same.</p> |
