Infrared touch screens, while useful in certain applications, have several notable disadvantages:Environmental Sensitivity:

一：Dust and Debris: Accumulation of dirt or moisture on the bezel can block infrared beams, impairing functionality.

二：Durability and Maintenance:Sensor Vulnerability: Damage to the infrared LEDs or photodetectors around the bezel can render the touchscreen inoperable.

三：Ambient Light Interference: Strong infrared sources, such as sunlight, can disrupt the sensor grid, leading to false touches or reduced accuracy.
