OPTICAL TOUCH MODULE AND OPTICAL TOUCH COMPONENT STRUCTURE

摘要

An optical touch component structure includes multiple optical touch modules and multiple L-shaped connection boards, which are assembled to form a frame body. Each optical touch module includes an LED circuit board and a control circuit board. The L-shaped connection boards are respectively connected to two ends of the control circuit boards. At least one first and second connector are disposed on correspondingly overlapping sections of the LED circuit board and the control circuit board and vertically mated with each other. Two outermost ends of the control circuit boards have two third connectors horizontally mated with fourth connectors of the L-shaped connection boards. A space exists between the LED circuit board and the control circuit board and between the LED circuit board and the L-shaped connection board. Electronic components are disposed in the space and an extension section of a filter member extends into the space.

主权项

1. An optical touch module comprising:
an LED circuit board having a first top face and a first bottom face, multiple LED components being disposed on the first top face, the first bottom face having at least one first connector; and a control circuit board positioned under the LED circuit board, the control circuit board having a second top face and a second bottom face, the second top face facing the first bottom face of the LED circuit board and having at least one second connector corresponding to the first connector and two third connectors respectively positioned at two outermost ends of the second top face of the control circuit board and misaligned from the first connector, the first and second connectors being vertically mated with each other so as to connect the control circuit board under the LED circuit board, a height gap existing between the LED circuit board and the control circuit board, whereby a space is positioned between correspondingly overlapping sections of the first bottom face of the LED circuit board and the second top face of the control circuit board, the first and second connectors being positioned in the space.
