An infrared touchscreen is characterized by a touch frame mounted in front of the display. This frame contains a printed circuit board equipped with a series of infrared LEDs and phototransistors hidden behind a bezel. The bezel protects these components from the external environment while allowing the infrared beam to pass through, creating a grid of invisible beams in front of the display.

Principle Of Operation
Infrared Frame: The commercial Infrared Touch Monitor is Surrounded By A Frame With Integrated Infrared Light-emitting Diodes (IR-LEDs) And Phototransistors (sensors).
IR Grid: The IR-LEDs Emit An Infrared Beam That Creates A Grid Of Invisible Light On The Surface Of The Screen.
Touch Detection: When A Finger Or Any Object Touches The Screen, The IR Beam Is Blocked. The Phototransistor Detects This Masking.
Position Mapping: The Sensor Calculates The Exact Position Of The Touch Based On Where The IR Beam Is Blocked. This Data Is Then Sent To The Device's Controller, Which Translates It Into The Appropriate Action On The Screen.
