OPTICAL TOUCH DISPLAY

摘要

An optical touch display includes a display panel, a lens module disposed at a corner of the display panel, and a processing unit. The lens module includes a circuit board, a first light receiving unit disposed on the circuit board, and a second light receiving unit disposed on the circuit board. The first light receiving unit has a first coordinate. The images provided by the first light receiving unit and the second light receiving unit are sent to the processing unit, and a distance between an object and the first light receiving unit is calculated by the processing unit, such that a second coordinated of the object on the display panel is obtained according to the first coordinate, the distance, and an angle defined by a line connecting the object to the first light receiving unit and an top edge of the display panel.
