Factory supply 85''Optical touching boards  

Features:

1. Positioning sensor technology:Optical Imaging Technology

2 Dual touch and dual user writing supported,

3.Fit for roduct size:78'',84'' and 88''

4.Resolution: ≥32768×32728

5.Very easy to maintain and repair  (just have 2 CCD cameras to replace if any problem.)

Applicantions:

1. Designed as an overlay on the LCD TV and functions like a LCD interactive whiteboard. This solution is also known as touch screen panel or simply touch panel.

2.Offered as SKD solution for regular interactive whiteboards.

 How does it work?

The solution kit includes the touch panel frame (with or without glass).

There are two major circuits on the left and right side of the solution kit. The CMOS sensor and the infrared diode lay almost back to back at each side.

In real life operation, the diodes emit invisible infrared light. The other three borders have light reflective tapes. The diodes emit invisible lights, when hitting objects it will reflects and detects by CMOS sensors via complex algorithm like Gaussian elimination of the coordination axis. The CMOS detection is analogous with a camera phone, grab a camera phone and a TV remote, press any key on the remote and take a shot, we can see the invisible light!
