MULTI-TOUCHABLE MODULIZED INFRARED TOUCH SCREEN MODULE

摘要

PURPOSE: A multi touchable modularized infrared touch screen is provided to raise accuracy by forming receiving sensors and transmitting LEDs as one module. CONSTITUTION: A primary module line(200) is formed by arranging modules(100) including ten or more receiving sensors and a transmitting LED on a front side of a board in a line. A secondary module line(250) corresponds to the first module line. The board senses a difference of a resistance value between the receiving sensors. The number of the receiving sensors on the front side of the board is from 30 to 35. The primary and secondary module lines are bilaterally symmetrical to each other.
