Abstract

The invention discloses an optical touch display which 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. Fields of views of the first light receiving unit and the second light receiving unit cover the display panel. The processing unit is electronically connected with the lens module. The processing unit calculates a coordinate on the display panel via images sent back through the first light receiving unit and the second light receiving unit.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to an optical touch panel. Background technique [0002] The touch technology combines the screen of the electronic device with the input module, and the user only needs to use a finger to press on the screen to operate. Touch devices can be classified into resistive, capacitive and optical. Because the optical touch device does not need to bury wires under the entire screen panel, it has a cost advantage in large-sized panels. [0003] However, the optical touch panel requires additional space for installing the light emitter and the light receiver. Therefore, how to reduce these extra space configurations so as not to affect the appearance of the product and take into account the advantages of the optical touch panel has become an important issue. subject. Contents of the invention [0004] Therefore, the object of the present invention is to provide an optical touch panel, which ...
