OPTICAL MULTI-TOUCH DEVICE AND ITS OPTICAL TOUCH MODULE

摘要

An optical touch module and an optical multi-touch device are disclosed. The optical touch module includes a glass panel, a control board unit and plural optical sensing sets. The glass panel is divided into a sensing zone and a peripheral zone surrounding the sensing zone. The control board unit is disposed on a rear surface of the glass panel and located completely within the peripheral zone. The optical sensing sets are disposed at intervals within the peripheral zone of the glass panel. The optical sensing sets are electrically connected to the control board unit, and the optical sensing sets and the control board unit jointly form a single-row serial connection structure.
