The perpendicular infrared ray matrix intersected.A circle is often scanned through, green light sensible if all of infrared tube represents to all go well.
When there is touch, finger or other things will block the infrared ray anyhow by the position, and touch-screen is sent out when scanning
Now and after having firmly believed that an infrared ray is obstructed, when red indicates that infrared ray is obstructed, and may have touch, while changing at once another
One coordinate is scanned again, if finding that an other axle also has an infrared ray to be obstructed again, amber light is bright, represents to find to touch, and by two
The individual infrared tube position for finding barrier is reported to main frame, judges touch point in the position of screen by calculating.
If but the antijamming capability of infrared touch panel currently on the market compares, so influencing whether infrared touch
The use of screen, so needing to be improved existing infrared touch panel.
