Abstract: An optical touch module includes an LED circuit board and a control circuit board. Multiple LED components are disposed on one face of the LED circuit board. The other face faces the control circuit board. The other face of the control circuit board is connected with the at least one L-shaped connection board. A first connector and a second connector are positioned in a space between overlapping sections of the LED circuit board and the control circuit board and mated with each other. The control circuit board has at least one third connector mated with a fourth connector of the L-shaped connection board. Electronic components and/or an extension section of a filter member are positioned in the space.

Abstract: A touch detection device for touchscreen includes a frame and at least one printed circuit board mounted on one face of the frame. The printed circuit boards have a plurality of transmitters, a plurality of receivers, and a wireless signal transmission unit mounted thereon. By using the transmitters and the receivers to detect touched positions on a touchscreen, and using the wireless signal transmission unit to transmit a touch signal, the touch detection device can be conveniently installed on the touchscreen with simplified cable wiring and avoid the risk of being undesirably pulled by an external force to adversely affect the signal transmission thereof.

Abstract: An optical touch device includes multiple optical touch modules and multiple L-shaped connection boards, which are assembled to form a frame body. Each L-shaped connection board is connected between two adjacent optical touch modules. Each optical touch module includes an LED circuit board and a control circuit board. Multiple LED components are disposed on one face of the LED circuit board. The other face faces the control circuit board. The other face of the control circuit board is connected with the L-shaped connection board. A first connector and a second connector are positioned in a space between overlapping sections of the LED circuit board and the control circuit board and mated with each other. The control circuit board has at least one third connector mated with a fourth connector of the L-shaped connection board. Electronic components and/or an extension section of a filter member are positioned in the space.

Abstract: 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.

Abstract: An optical touch assembly includes a plurality of optical touch modules connected to one another via L-shaped coupling plates to form a frame. Every optical touch module includes a light-emitting-diode (LED) circuit board having a plurality of LED elements mounted thereto and a control circuit board located below and overlapped with the LED circuit board. The L-shaped coupling plates connected to two opposite ends of each optical touch module are located below and overlapped with the LED circuit board. First connectors are provided on a bottom surface of the LED circuit board for correspondingly vertically connecting to second and third connectors provided on the control circuit board and the L-shaped coupling plates, respectively, so that intermediate spaces are formed in overlap areas between the LED circuit board and the control circuit board and the L-shaped coupling plates for mounting electronic elements and an extended section of a filter therein.
