84 inch portable interactive whiteboard.In early concepts, infrared touch screens had technical limitations such as low resolution, limited touch methods, and susceptible to environmental interference and malfunction, so they once faded out of the market. After that, the second generation of infrared screens partially solved the problem of anti-light interference. The third and fourth generations also improved the resolution and stability performance, but they did not make a qualitative leap in key indicators or comprehensive performance. However, anyone who knows touch screen technology knows that infrared touch screens are not affected by current, voltage and static electricity and are suitable for harsh environmental conditions. Infrared technology is the ultimate development trend of touch screen products. Touch screens using acoustic and other materials technologies have their insurmountable barriers, such as damage and aging of a single sensor, fear of contamination of the touch screen interface, destructive use, and complicated maintenance. As long as the infrared touch screen truly achieves high stability and high resolution, it will certainly replace other technical products and become the mainstream of the touch screen market.
